The present invention relates to a modular partition system for forming a partition and parts therefor. In particular, but not exclusively, the partition may be a thermally insulating or sound insulating partition. The partition may, for example, form part of a building and may be a roof, a wall or a floor.
Structurally insulating panels (SIPS) provide an alternative to more traditional forms of construction. SIPS comprise an insulation board or panel which is sandwiched between two structural panels, SIPs may be used in the construction of roofs, walls and even floors.
One benefit of construction that uses SIPs is that it aids in the facilitation of offsite construction wherein buildings are fabricated in a factory before being shipped to site. Another benefit of construction that uses SIPs is that it may aid in the construction of a well-insulated and sealed building since generally SIPs are generally manufactured as large sheet materials which may result in fewer joints and less opportunity for air leaks.
Although this type of construction (using SIPs) has various benefits it is not universally adopted because it can be more expensive than other more traditional forms of construction. Therefore, construction that uses SIPS is mainly used where either speed of build or envelope performance are the overriding factors.
It is desirable to provide a system for constructing a partition that at least partially addresses one or more of the problems of the prior art, whether identified herein or elsewhere.
According to a first aspect of the present invention there is provided a modular partition system comprising: a plurality of panels, each of the plurality of panels comprising two support members extending generally perpendicularly to a plane of the modular partition system and a central panel extending between said two support panels, the plurality of panels being arranged such that the central panels of each of the plurality of panels are generally mutually parallel and one support member of each of the plurality of panels is adjacent to a support member of an adjacent panel; and at least one connecting strip; wherein the at least one connecting strip cooperates with a support member from each of two of the plurality of adjacent panels so as to connect said two of the plurality of adjacent panels.
It will be appreciated that as used herein the terms panel, sheet and board are intended to mean a relatively thin, generally flat three-dimensional object or body. It will be further appreciated that by relatively thin it is meant that one dimension of the object or body is smaller than the other two dimensions of the object or body. The smallest dimension of the object or body may be referred to as its thickness. The two dimensions generally perpendicular to the smallest dimension of the object or body may define a plane (or family of parallel planes). Such panels, sheets and boards may, for example, be generally rectangular.
The first aspect of the invention provides a particularly versatile and cost effective system for constructing a partition which provides a number of advantages over the prior art, as now discussed.
In particular, the first aspect of the invention provides a system for constructing a partition which is self-supporting. In particular, the system forms a self-supporting structure which can bear a load such as, for example, a roof, a wall or a floor of a building. Generally, the system comprises a plurality of panels and a pair of connecting strips arranged to cooperate with a support member from each of two adjacent panels. The bulk of each panel is non-load bearing in use and may provide thermal or sound insulation. The support members of two adjacent panels, along with two connecting strips co-operate to form a self-supporting, load bearing I beam.
The modular partition system of the first aspect provides an alternative to prior art construction panels such as, for example, structurally insulating panels (SIPs). Within an SIP the insulation is sandwiched between two structural panels (i.e. two panels placed on the inside and outside surfaces of the construction panel). SIP panels are not only used for roofs but also generally for construction building walls and floors. Furthermore, SIPs are generally manufactured as large sheet materials that may form an entire, or at least a significant portion of, a partition. This is an intentional feature of prior art SIP systems which is intended to reduce the number of joints in the hope that this will provide less opportunity for air leaks.
Advantageously, the system according to the first aspect of the invention uses panels wherein the support members are disposed on the sides of the central panels extending generally perpendicularly to a plane of the modular partition system. As a result, the modular system according to the first aspect may use significantly less structural support material than is required for an equivalent SIP panel. As a result, the system according to the first aspect is significantly lighter and is significantly cheaper to produce. In addition, since the support members of the panels extend generally perpendicularly to a plane of the modular partition system, there is no need for any load to be transmitted through the central panel (in contrast to SIPs). Therefore, any connection (for example adhesive bonding) between the support members and the central panel does not need to be of high integrity. This further reduces the manufacturing costs of the system of the first aspect relative to the prior art.
Furthermore, contrary to the teachings of the prior art, the modular partition system of the first aspect lends itself better to an arrangement with a larger number of panels and, consequently, a larger number of joins. This has been allowed, at least in part, due to the provision of the at least one connecting strip which cooperates with a support member from each of two of the plurality of adjacent panels so as to aid a structural connection between two adjacent panels. Since the system of the first aspect allows such smaller panels, it can result in a further cost benefit since the quantity of waste material, for example at apertures in the partition (e.g. doors and windows) and at the joins between partitions (e.g. the corner of a room) can be significantly reduced or even eliminated completely.
Furthermore, because the system of the first aspect allows such panels, it can be significantly easier to install. For example, it may be easier for the panels of the system of the first aspect to be manually installed, removing the need for lifting apparatus (e.g. a crane or the like), which can be costly and can lead to costly delays on construction sites (e.g. if the lifting apparatus is temporarily unavailable).
The central panel of each of the plurality of panels may comprise any suitable material.
In some embodiments, the central panel of each of the plurality of panels may comprise a thermally insulating material. For example, the material may be a rigid insulation material such as, for example, expanded polystyrene (EPS), extruded polystyrene (XPS), rigid polyurethane (PUR), polyisocyanurate (PIR). The material may be either closed cell or open cell. Such embodiments, wherein the central panel of each of the plurality of panels comprises a thermally insulating material, may be particularly suitable when the partition forms part of a roof or an external wall of a building.
Alternatively, particularly for embodiments when the partition forms part of an internal wall or floor of a building, the central panel of each of the plurality of panels may comprise a cheap material that merely provides a connection between the two support members of the panel. For example, the material may comprise cardboard.
In some embodiments, the central panel of each of the plurality of panels may comprise a sound insulating material. Such embodiments may be particularly suitable when the partition forms part of an internal wall or floor of a building.
Each of the support members of the plurality of panels may comprise: a support panel extending generally perpendicularly to a plane of the central panel.
The support panels may be formed from any suitable material. Suitable materials may include hardboard and high density fibreboard (HDF).
The support panels may be bonded to the central panels using a suitable adhesive. This may keep the elements of the panel together thus making transportation of the panel (for example to a construction site) easier.
Each of the support members of the plurality of panels may comprise a protruding portion which extends beyond at least one of the surfaces of the central panel.
That is, the panels are arranged such that on each of four edges of the panel, a protruding portion of one of the support members stands proud of the central panel. This offers a further benefit over prior art arrangements (for example SIPs), as now explained. Since each of the support members extends beyond at least one of the surfaces of the central panel the partition does not have a smooth, flat surface. Rather, the protruding portions of the support members from each pair of adjacent panels form a ridge on each surface of the partition (which is generally defined by the generally mutually parallel surfaces of the central panels).
With prior art arrangements, for example SIPs, battens need to be added to the internal surface of the construction panel for fire and electrical cabling reasons. Typically, an internal board (for example plasterboard) is fixed to said battens. When used as a roof, on the external surface of a SIP, battens are attached for supporting roof tiles. However, these battens are required to be held off the external surface of the SIP with a counter batten to aid water drainage. With the system according to the first aspect, the internal battens and the additional external counter battens are not required (due to the ridges on each surface of the partition formed by the protruding portions of the support panels from each pair of adjacent panels).
Each of the support members of the plurality of panels may comprise a flange portion extending generally parallel to the plane of the central panel.
Such an arrangement provides a greater surface area at each end of the support members, which is beneficial for a variety of reasons. First, with this arrangement the profile of the support member is generally half of an I shape. That is, the two support members from two adjacent panels which are in contact together are generally of the form of an I beam. The increased surface area of the support members provided by the flanges better distributes any load carried by the modular partition system. Second, the increased surface area may make it easier for an internal or external cladding to be fixed to the partition.
The modular partition system may further comprise a resilient between each pair of adjacent panels.
For example, a side surface of either or both of the two support members may be provided with a sealing material (for example a foam tape or the like).
In at least one direction the at least one connecting strip may extend beyond the support members from the two adjacent panels which it is arranged to cooperate with.
This allows the connecting strip to extend beyond the plurality of panels and over, for example, a beam to help with the connection of the modular partition system to the beam and provide a counter batten on a top surface of the beam.
The at least one connecting strip may be provided with one or more engagement features for engagement with a batten and/or a wall tie.
This further simplifies constructions which use the modular partition system. When used as a roof, a plurality of battens may be provided on an external surface of the modular partition system to support roof tiles. When used as a wall (for example the inner leaf of a cavity wall), a plurality of wall ties may be provided on an external surface of the modular partition system to connect it to an outer leaf of the cavity wall (for example a brick wall).
According to a second aspect of the invention there is provided a panel for a partition, the panel comprising: a central panel; and two support panels disposed on opposed sides of the central panel, each of the two support panels extending generally perpendicularly to a plane of the central panel.
The panel may be suitable for use in the modular partition system of the first aspect of the invention.
The second aspect of the invention provides a construction panel wherein structural support is provided by the two support panels placed on opposite sides of the central panel, which may, for example, be formed from a thermally insulating material. This is in contrast to prior art insulated construction panels such as, for example, structurally insulating panels (SIPS) wherein where the insulation is sandwiched between two structural panels (i.e. two panels placed on the inside and outside surfaces of the construction panel).
Advantageously, a panel according to the second aspect of the invention may use significantly less structural support board than is required for an equivalent SIP panel. Furthermore, the support boards may be thinner than the structural support board that is used in SIP panels. As a result, the panel according to the second aspect is significantly lighter and is significantly cheaper to produce.
In some embodiments, the central panel may comprise a thermally insulating material. For example, the material may be a rigid insulation material such as, for example, expanded polystyrene (EPS), extruded polystyrene (XPS), rigid polyurethane (PUR), polyisocyanurate (PIR). The material may be either closed cell or open cell. Such embodiments, wherein the central panel comprises a thermally insulating material, may be particularly suitable when the panel forms pa part of a roof or an external wall of a building.
Alternatively, particularly for embodiments when the panel forms part of an internal wall or floor of a building, the central panel may comprise a cheap material that merely provides a connection between the two support members of the panel. For example, the material may comprise cardboard.
In some embodiments, the central panel may comprise a sound insulating material. Such embodiments may be particularly suitable when the panel forms part of an internal wall or floor of a building.
The support panels may be formed from any suitable material. Suitable materials may include hardboard and high density fibreboard (HDF).
The support panels may be bonded to the central panel using a suitable adhesive. This may keep the elements of the panel together thus making transportation of the panel (for example to a construction site) easier.
A protruding portion of the each of the two support panels may extend beyond at least one of the faces of the central panel.
That is, the panel is arranged such that on each of four edges of the panel, a protruding portion of one of the support panels stands proud of the central panel. This offers a further benefit over prior art arrangements (for example SIPs), as now explained. A partition may be formed from a plurality of panels according the second aspect, the plurality of panels being arranged in a row such that a support panel of each panel is adjacent to, and in contact with, a support panel of an adjacent panel. Since each of the support panels extends beyond at least one of the sides of the central panel, such a partition formed from a plurality of panels according to the second aspect does not have a smooth, flat surface. Rather, the protruding portions of the support panels from each pair of adjacent panels form a ridge on each surface of the partition (which is generally defined by the surfaces of the central panels).
With prior art arrangements, for example SIPs, battens need to be added to the internal surface of the construction panel for fire and electrical cabling reasons. Typically, an internal board (for example plasterboard) is fixed to said battens. When used as a roofing panel, on the external surface of a SIP, battens are attached for supporting roof tiles. However, these battens are required to be held off the external surface of the SIP with a counter batten to aid water drainage. With the panel according to the second aspect, the internal battens and the additional external counter battens are no required (due to the ridges on each surface of the partition formed by the protruding portions of the support panels from each pair of adjacent panels).
The panel may further comprise a flange extending from at least one protruding portion of the two support panels, said flange extending generally parallel to the plane of the central panel.
Each support panel and the flanges extending therefrom together provide a support member. It will be appreciated that such a support member may be formed from separate support panel and flange members, which are structurally connected. Alternatively, the separate support panel and flange members may be integrally formed.
Such an arrangement provides a greater surface area at each end of the support panels, which is beneficial for a variety of reasons. First, with this arrangement the profile of the support member is generally half of an I shape. That is, in use, when the two support members from two adjacent panels are in contact, together they are generally of the form of an I beam. The increased surface area of the support members provided by the flanges better distributes any load carried by a partition formed from the panels. Second, the increased surface area may make it easier for an internal or external cladding to be fixed to a partition formed from the panels.
The or each flange may be provided by a flange member which is formed from a metal material and which is structurally connected to the support panel.
For example, each flange member may comprise a rolled light gauge steel strip which is mechanically attached to the support panel (which may be formed from a better thermally insulating material such as hardboard). Optionally, each flange member may comprise a timber about which the light gauge steel strip is rolled.
A side surface of either or both of the support panels may be provided with a resilient sealing material.
For example, a foam tape or the like may be applied to one or both sides of the panel. In use, this can enhance the sealing of adjacent panels.
According to a third aspect of the invention there is provided a connecting strip for use in the modular partition system of the first aspect of the invention, the connecting strip comprising: an elongate body defining a groove for receipt of a portion of a support member from each of two of a plurality of adjacent panels: wherein the elongate body is provided with one or more engagement features for engagement with a batten and/or a wall tie.
The engagement features may be provided at any convenient separation along the connecting strip.
Each engagement feature may comprise at least one pair of protrusions, each of the protrusions defining a guide channel for at least part of a batten, the guide channels of the pair of protrusions facing each other.
Each protrusion may be generally L shaped and may comprise a first portion which extends generally perpendicularly from a surface of the connecting strip and a second portion, distal from said surface of the connecting strip which extends generally parallel to said surface of the connecting strip so as to define the guide channel.
Each engagement feature may comprise two pairs of protrusions.
In use, a batten may be installed by sliding it in a direction generally parallel to the batten (and generally perpendicular to the connecting strip) so that a side portion of the batten is received in each of the guide channels formed by the at least one pair of protrusions.
Each engagement feature may comprise at least one generally L shaped protrusion defining a guide channel for receipt of a batten.
In use, the connecting strip is installed such that the guide channels defined by the protrusions face generally upwards (for example towards a ridge beam).
A timber batten or the like may be installed by sliding it into the guide channels of a plurality of said connecting strips in a direction generally perpendicular to the batten (and generally parallel to the connecting strips).
On either side of the groove the elongate body may define a plurality of pairs of features for engaging the ends of a wire wall tie.
According to a fourth aspect of the invention there is provided a building comprising the modular partition system of the first aspect of the invention.
The modular partition system may form any of the following; a roof partition, a wall or a floor within the building.
According to a fifth aspect of the invention there is provided a kit of parts for a modular partition system comprising: a plurality of panels, each of the plurality of panels comprising two support members extending generally perpendicularly to a plane of the modular partition system and a central panel extending between said two support panels, the plurality of panels being arranged such that the central panels of each of the plurality of panels are generally mutually parallel and one support member of each of the plurality of panels is adjacent to a support member of an adjacent panel; and at least one connecting strip arranged to cooperate with a support member from each of two of the plurality of adjacent panels so as to connect said two of the plurality of adjacent panels.
Each of the plurality of panels may comprise a panel according to the second aspect of the invention.
The at least one connecting strip may comprises a connecting strip according to the third aspect of the invention.
The kit of parts may further comprise at least one resilient seal for sealing a gap between each pair of adjacent panels.
For example, a side surface of either or both of the two support members may be provided with a sealing material (for example a foam tape or the like).
According to a sixth aspect of the invention there is provided a support beam comprising: a web panel having first and second opposed surfaces; a first flange attached to the web panel proximate a first edge of the web panel; and a second flange attached to the web panel proximate to the second edge of the web panel, wherein the first and second flanges are formed from a metal material; and wherein the first and second flanges are each attached to the first and second opposed surfaces.
The support beam is generally of the form of an I beam. The support beam may be suitable for use as a joist in part of a surface such as a floor, wall or ceiling.
The support beam according to the first aspect of the present invention is advantageous over known support beams, as now discussed.
Traditional floor joists are formed from solid timber beams. It has become increasingly common to use an I beam construction for floor joists. One known type of I beam that is used as a floor joist in the construction of buildings comprises a web formed from oriented strand board (OSB) and two solid flanges formed from timber. The OSB web is partially received in a groove in each of the solid timber flanges and attached thereto using adhesive to provide a connection which can resist shear forces.
In contrast to such known I beams or I joists, the support beam according to the first aspect of the present invention uses first and second flanges which are formed from a metal material. This offers a significant advantage over the known arrangement since, unlike timber, metal materials may be formed to arbitrary lengths, for example using a range of continuous processes. Therefore, the support beam according to the first aspect of the present invention can be easily manufactured to a range of different lengths. This allows the support beam to be manufactured to the required length for each purpose with substantially no waste.
Furthermore, there are a number of additional advantages of using metal flanges as opposed to timber flanges, including cost, weight and formability.
In addition, the support beam is formed from three parts (the web panel, the first flange and the second flange), which are attached together (the first and second flanges being attached to the first and second opposed surfaces of the web panel). This provides significant advantages over, for example, a typical rolled steel joist (RSJ) which is typically formed entirely from solid steel. This construction, whereby the support beam is formed from three parts which are attached together, advantageously, allows the use of more economical and lighter materials to be used for the web panel. Furthermore, it allows the first and second flanges to be formed as generally tubular or hollow structures, providing further cost and weight savings.
The support beam according to the first aspect comprises first and second flanges which are metal and which are attached to the first and second opposed surfaces of the web panel. It will be appreciated that the attachment of the first and second flanges to the web panel is an attachment which provides resistance to shear forces (the shear plane of the support beam being the plane of the web panel).
It will be further appreciated that as used herein the terms panel, sheet and board are intended to mean a relatively thin, generally flat three-dimensional object or body. It will be further appreciated that by relatively thin it is meant that one dimension of the object or body is smaller than the other two dimensions of the object or body. The smallest dimension of the object or body may be referred to as its thickness. The two dimensions generally perpendicular to the smallest dimension of the object or body may define a plane (or family of parallel planes). Such panels, sheets and boards may, for example, be generally rectangular.
It will be appreciated that the first and second flanges extend beyond the first and second surfaces of the web panel in a direction generally perpendicular to a plane of the panel.
The web panel may comprise engineered wood.
For example, the web panel may comprise a composite material board or panel. For example, the web panel may comprise OSB, hardboard, mdf, chipboard, plywood or the like.
The web panel may comprise a single panel.
Such embodiments may be preferred over, for example, embodiments comprising two or more panels since such arrangements with two or more panels would require some physical connection that can tie them together so as to resist shear forces (in the plane of the web panel).
In cross section the first and/or second flanges may be of the form of a hollow or tubular structure.
In cross section the first and/or second flanges may comprise a continuous loop of material from the first surface to the second surface.
In cross section the continuous loop of material from the first surface to the second surface may be generally uniform in cross section.
The continuous loop of material may comprise a first portion that is in contact with the first surface and a second portion that is in contact with the second surface.
The first and/or second flanges may be formed from sheet metal.
For example, the sheet metal may be formed by a light gauge steel strip. The sheet metal may, for example, be folded or rolled to form the first and second flanges.
Alternatively, the first and second flanges may be formed using another process, for example a continuous process such as extrusion.
As previously discussed, the attachment of the first and second flanges to the first and second surfaces of the web panel is an attachment which provides resistance to shear forces (the shear plane of the support beam being the plane of the web panel).
The attachment of the first and second flanges to the first and second surfaces of the web panel may prevent movement of the first and second flanges relative to the web panel. The attachment of the first and second flanges to the first and second surfaces of the web panel may be sufficient to resist shear forces of the order of 2.5 kN or more.
It will be appreciated that the attachment of the first and second flanges to the first and second surfaces of the web panel may be achieved in a variety of different ways.
The attachment of the first and/or second flanges to the first and second surfaces of the web panel may be via surfaces of the first and/or second flanges which are complementary to and in engagement with the first or second surfaces.
It will be appreciated that such an engagement may be achieved via plastic deformation of the mutually engaging surfaces (which may be flat prior to said plastic deformation). Such plastic deformation may be achieved, for example, by using a punch to crimp the two surfaces together. For example, a punch may be used to cause the first and second flanges to bite into the web panel.
Alternatively, the attachment of the first and second flanges to the first and second surfaces of the web panel may be achieved using screws, nails, rivets or other mechanical fixing.
The first and/or second flanges may comprise: a wall portion which is generally perpendicular to a plane of the web panel.
The wall portion may be provided with a feature for engagement with the first or second edge of the web panel.
Such an engagement feature may, for example, be formed on an interior surface of the first and second flanges.
The support beam may further comprise a resiliently deformable member provided on the wall portion of at least one of the first and second flanges.
Such a resiliently deformable member may provide some reduction in the amount of sound that is transmitted through a structure formed using the support beam. For example, the support beam may form a joist for a floor. For example, the resiliently deformable member may be provided on one of the first and second flanges that in use will form a top of the joist (and which may support floorboards or the like). The resiliently deformable member can absorb some sound and therefore at least partially prevent sound from being transmitted through the floor.
The resiliently deformable may comprise a foam material.
The support beam may further comprise at least one elongate metal member, the elongate member being movably connected to the first or second flange and the resiliently deformable member being disposed between the elongate metal member and the first or second flange.
For example the elongate metal member may be formed from a light gauge steel strip that is shaped such that it can engage over the first or second flange using a snap fit type coupling such that the resiliently deformable is held captive between the elongate metal member and the first or second flange. Advantageously, this provides an integrated arrangement that aids the ease of installation of such soundproofing solutions.
A known and currently used method to prevent sound transmission through an intermediate floor is to screw resilient bars, in the form of a light gauge steel Z-section, to the bottom surface of timber floor joists. A ceiling substrate (for example plasterboard) is then attached to the resilient bars, which reduce the transmission of sound from the floor to a space there below.
The support beam may further comprise one or more engagement features for connection to a resilient bar, the one or more engagement features being provided on the wall portion of at least one of the first and second flanges.
For example, the engagement features for connection to a resilient bar may be of the form of one of more generally L-shaped protrusions from the wall portion, said protrusions forming a groove for receipt of a portion of a resilient bar. Including these engagement features, for example on one of the first and second flanges that in use will form a bottom of the support beam will improve compliance and speed up installation. The ease of provision of such features on the first and second flanges is a further advantage of the support beam according to the first aspect of the invention, which uses metal flanges.
The support beam may further comprise one or more hanging features for connection to a supporting structure that is generally perpendicular to the support beam, the one or more hanging features being provided on at least one of the first and second flanges.
Steel joist hangers are used to support the ends of a beam at a supporting structure that is generally perpendicular to the beam (for example a wall or a perpendicular supporting beam). Light gauge steel is used and requires many fixings between the joist hanger and the beam to ensure the structural performance. It is common in construction for installers to not put enough in fixings in (saving time). The one or more hanging features are integrally formed with the support beam and therefore facilitate quick and safe installation.
According to a seventh aspect of the invention there is provided a support beam comprising: a plurality of the support beams according to the sixth aspect of the invention, the plurality of support beams being arranged so as to be mutually adjacent and parallel; a first elongate connection member arranged to connect to the first flanges of the all of the plurality of support beams; and a second elongate connection member arranged to connect to the second flanges of the all of the plurality of support beams.
For example the first and second elongate connection members may be formed from a light gauge steel strip that is shaped such that it can engage over the first or second flanges of all of the plurality of support beams using a snap fit type coupling. Additional fixings may be provided between the first and second elongate connection members and the first or second flanges of all of the plurality of support beams.
In the design of an intermediate floor or similar a beam may be required to carry several other beams or joists. The support beam according to the second aspect of the invention provides an arrangement having increased strength and second moment of area suitable for such applications.
According to an eighth aspect of the invention there is provided a method of forming the support beam according to the sixth aspect of the invention, the method comprising: providing a web panel; providing a first flange formed from a metal material; providing a second flange formed from a metal material; attaching the first flange to the web panel proximate a first edge of the web panel; and attaching the second flange to the web panel proximate to a second edge of the web panel; and wherein the first and second flanges are each attached to first and second opposed surfaces of the web panel.
Attaching the first flange to the web panel proximate a first edge of the web panel may comprise: positioning the first flange adjacent to the first edge of the web panel such that a first portion of the first flange is adjacent the first surface of the web panel and a second portion of the first flange is adjacent the second surface of the web panel; and using a punch to crimp the first portion of the first flange to the first surface of the web panel in at least one position; and using a punch to crimp the second portion of the first flange to the second surface of the web panel in at least one position.
Attaching the second flange to the web panel proximate a second edge of the web panel may comprise: positioning the second flange adjacent to the second edge of the web panel such that a first portion of the second flange is adjacent the first surface of the web panel and a second portion of the second flange is adjacent the second surface of the web panel; and using a punch to crimp the first portion of the second flange to the first surface of the web panel in at least one position; and using a punch to crimp the second portion of the second flange to the second surface of the web panel in at least one position.
Various aspects and features of the invention set out above or below may be combined with various other aspects and features of the invention as will be readily apparent to the skilled person.
Embodiments of the invention will now be described, by way of example only, with reference to the accompanying schematic drawings in which corresponding reference symbols indicate corresponding parts, and in which:
A novel panel 2 for a partition according to an embodiment of the invention is shown in
It will be appreciated that as used herein the term panel is intended to mean a relatively thin, generally flat three-dimensional object or body. It will be further appreciated that by relatively thin it is meant that one dimension of the object or body is smaller than the other two dimensions of the object or body. The smallest dimension of the object or body may be referred to as its thickness. The two dimensions generally perpendicular to the smallest dimension of the object or body may define a plane (or family of parallel planes).
In
The insulation panel 4 may comprise any suitable insulation material. For example, the material may be a rigid insulation material such as, for example, expanded polystyrene (EPS), extruded polystyrene (XPS), rigid polyurethane (PUR), polyisocyanurate (PIR). The material may be either closed cell or open cell. The thickness of the insulation panel 4 may be determined by bearing in mind building regulations or codes to which it is desired for buildings incorporating the panel 2 to meet. There is a general trend in the construction industry for increasing thicknesses of insulation to be installed in partitions. Merely as an example, the insulation panel 4 may have a thickness of the order of 175 mm.
The support panels 6 may be formed from any suitable material. Suitable materials may include hardboard and high density fibreboard (HOF).
As can be best seen in
Therefore, the panel 2 is arranged such that on each of four edges of the panel 2, a protruding portion 8 of one of the support panels 6 stands proud of the insulation panel 4.
The panel 2 further comprises a flange extending from each protruding portion 8 of the two support panels 6, said flange extending generally parallel to the plane of the insulating panel 4. In the embodiment shown in
Each timber batten 16 is disposed adjacent to the protruding portion 8 of one of the support panels 6 and one of the faces 10, 12 of the insulating panel 4. Each steel strip 14 comprises a first portion which is adjacent to an external face of the one of the support panels 6 (that is a face of the support panel 6 which is opposed to the insulating panel 4) and a second portion which extends generally parallel to the plane of the insulating panel 4. The second portion of the steel strip 14 may be wrapped round the timber batten 16 so as to retain it in place.
The first portion of each steel strip 14 is mechanically attached to one of e support panels 6 by one or more fixings 18 (see
Each support panel 6 and the flanges extending therefrom together may be considered to provide a support member. That is, one support panel 6, two steel strips 14 and, optionally, two timber battens 16 may be considered to form a support member.
In
The panel 2 may be of any width. The width of the panel 2 may be selected bearing in mind both: the amount of support required for the overall structural stability of the panel and/or the requirements of any substrate which, in use, the panel 2 is intended to support. For example, in use the panel may support plasterboard (on an interior surface thereof) which is typically supported at a maximum of 600 mm centres. Therefore, in one embodiment, the panel 2 may have a width of around 600 mm to accommodate this. The support panels 6 may have a thickness of around 6 mm. In order for the overall thickness of the panel 2 to be 600 mm, the width of the insulation panel 4 will be 588 mm. Therefore, across the width of the panel 2 there will be 12 mm of support panel material (for example hardboard) and 588 mm of insulation, i.e. 2% structure and 98% insulation.
The panel 2 shown in
Advantageously, the panel 2 uses significantly less structural support board than is required for an equivalent SIP panel. Furthermore, the support boards 6 may be thinner than the structural support board that is used in SIP panels. As a result, the panel 2 is significantly lighter and is significantly cheaper to produce.
The provision of a protruding portion 8 of the each of the two support panels 6 that extends beyond the faces 10, 12 of the insulating panel 4 offers a further benefit over prior art arrangements (for example SIPs), as now explained. A partition may be formed from a plurality of the panels 2, the plurality of panels being arranged in a row such that a support panel 6 of each panel 2 is adjacent to, and in contact with, a support panel 6 of an adjacent panel 2. Since each of the support panels 6 extends beyond at least one of the sides of the insulating panel, such a partition formed from a plurality of the panels 2 does not have a smooth, flat surface. Rather, the protruding portions 8 of the support panels 6 from each pair of adjacent panels 2 form a ridge on each surface of the partition (which is generally defined by the surfaces of the insulating panels 4).
With prior art arrangements, for example SIPs, battens need to be added to the internal surface of the construction panel for fire and electrical cabling reasons. Typically, an internal board (for example plasterboard) is fixed to said battens. When used as a roofing panel, on the external surface of a SIP, battens are attached for supporting roof tiles. However, these battens are required to be held off the external surface of the SIP with a counter batten to aid water drainage. With the panel 2 shown in
The provision of a flange extending from each protruding portion 8 of the two support panels 6 (as provided by the rolled light gauge steel strip 14 and the timber batten 16) provides a greater surface area at each end of the support panels 6, which is beneficial for a variety of reasons. First, with this arrangement the profile of the support member is generally half of an I shape. That is, in use, when the two support members from two adjacent panels 2 are in contact, together they are generally of the form of an I beam. The increased surface area of the support members provided by the flanges better distributes any load carried by a partition formed from the panels 2. Second, the increased surface area may make it easier for an internal or external cladding to be fixed to a partition formed from the panels 2.
The support panels 6 may be bonded or adhered to the insulation panel 4. This may be convenient since it may make each panel 2 a more easily transportable assembly. However, since the support panels 6 of the panel 2 extends generally perpendicularly to a plane of the panel 2, there is no need for any load to be transmitted through the insulating panel 4 (in contrast to SIPs). Therefore, any connection (for example adhesive bonding) between the support members 6 and the insulating panel 4 does not need to be of high integrity. This further reduces the manufacturing costs of the system of the first aspect relative to the prior art.
The support panels 6 will not have the same thermal performance as the insulation panel 4 and will typically reduce the thermal performance of the overall assembly in comparison to a construction with insulation alone. To reduce this effect the thickness of the support members 6 may be minimised and the material from which they are formed may be chosen to maximise the thermal performance of the panel fulfilling the structural roll.
The panel 2 may have any length as desired. It has been found that a panel with the features as described above may be able to span distances of around 6.5 m. It is envisaged that the construction of the panel may be such that it will only be cut to length by order. It is expected that this may reduce material waste significantly.
For embodiments wherein the panel 2 is intended to be used to span a pitched roof, one end of the panel 2 is provided with an end support panel 20. The end support panel 20 may be bonded or adhered to the insulating panel 4. Additionally or alternatively, the end support panel 20 may be attached to the timber battens 16 via fixings 22. The fixings 22 may be, for example, punches, rivets, screws, nails or the like.
As can be seen in
As explained above, the support panels 6 may be bonded or adhered to the insulation panel 4, which may make each panel 2 more easily transportable assembly. An alternative arrangement is now described with reference to
The flanges extending from each protruding portion 8 of the two support panels 6 generally parallel to the plane of the insulating panel 4 comprise a modified rolled light gauge steel strip 28.
Each steel strip 28 comprises a first portion which is adjacent to an external face of the one of the support panels 6 (that is a face of the support panel 6 which is opposed to the insulating panel 4) and a second portion 32 which extends generally parallel to the plane of the insulating panel 4.
The second portion 32 of the steel strip is rolled or folded so as to be generally of the form a box beam. To achieve this, the steel strip 28 is rolled or folded such that the second portion 32 of the steel strip comprises: a portion 32a which extends generally parallel to, and is spaced apart from, a surface of the insulating panel 4; a portion 32b which extends generally towards a surface of the insulating panel 4; a portion 32c which extends generally parallel to, and adjacent to, a surface of the insulating panel 4; and a portion 32d which extends generally away from a surface of the insulating panel 4. It will be appreciated that the steel strip 28 may be formed by rolling or folding a sheet of steel at the intersection between each adjacent portion.
A distal end 34 of the second portion 32 is generally parallel to the first portion 30. Together the distal end 34 of the second portion 32 and the first portion 30 define a channel or groove 36 for receipt of the protruding portion 8 of one of the two support panels 6. Said channel or groove 36 defined by the distal end 34 of the second portion 32 and the first portion 30 may be dimensioned so as to form an interference fit with the protruding portion 8 of one of the two support panels 6. This may aid in assembly of the panel, keeping the steel strips 28 in place before retaining them with one or more fixings (in an analogous manner to the panel 2 shown in
The second portion 32 of each steel strip 28 is provided with a means for engaging with a face 10, 12 of the insulating panel 4. In particular, second portion 32 of each steel strip 28 is provided with a plurality of discrete or intermittent barbs 37 arranged to pierce or penetrate the insulating panel 4 so as to engage therewith. The barbs 37 are formed from a plurality of portions of the sheet material which are not rolled or folded when the intersection between the portion 32b which extends generally towards a surface of the insulating panel 4 and the portion 32c which extends generally parallel to, and adjacent to, a surface of the insulating panel 4 is formed.
Some embodiments of the invention relate to a modular partition system comprising: a plurality of panels (for example the panels 2, 26 described above) and at least one connecting strip arranged to cooperate with a support member from each of two of the plurality of adjacent panels. Such a connecting strip may take various different forms as now described with reference to
Each of
Generally, each type of connecting strip 38, 40, 42 shown in
It will be appreciated that, in use, generally two connecting strips 38, 40, 42 are provided for each pair of adjacent panels, the two connecting strips 38, 40, 42 being provided at opposite ends of the support members.
A further embodiment of a modular partition system comprising: a plurality of panels and at least one connecting strip arranged to cooperate with a support member from each of two of the plurality of adjacent panels is now described with reference to
The only difference between the panels 132 of this embodiment and the panel 2 shown in
As can be best seen in
The connecting strip 134 (see
The connecting strip 134 (which may be formed from rolled steel) is generally of the form of a box beam but having an aperture for receipt of part of the two support panels proximate an edge thereof and part of the steel strip 136 proximate the edges of the support panels. In particular, the connecting strip 134 comprises a central wall portion 134a and two generally U-shaped side portions 134b, 134c. The channel or groove for receipt of part of the flanges of the support members 6 of two adjacent panels 132 is formed between the two side portions 134b, 134c.
Between the second and third portions 140, 142, each steel strip 136 comprises a protrusion portion 141, which extends out away from the interior surface 6a of the support panel 6. The protrusion portions 141 are dimensioned such that the protrusion portions 141 of the two adjacent panels 132 are slightly larger than an opening of the channel or groove formed between the two side portions 134b, 134c. However, connecting strip 134 can resiliently deform sufficiently to allow the protrusion portions 141 of the two adjacent panels 132 to be received in the channel or groove. Once the protrusion portions 141 of the two adjacent panels 132 have passed the two side portions 134b, 134c, the connecting strip 134 can snap back such that the protrusion portions 141 are held captive in the groove or channel.
At a distal end of the fourth portion of the steel strip 136 is provided with a barbed portion 146, which provide with a means for engaging with a face of the insulating panel 4. The barbed portion 146 is similar to the barbs 37 of the embodiment shown in
The first portion 138 of each steel strip 136 is mechanically attached to the exterior surface 6b one of the support panels 6. Similarly, the third portion 142 of each steel strip 136 is mechanically attached to the interior surface 6a one of the support panels 6. In this embodiment, this is achieved by crimping the first portion 138 of the steel strip 136 to the exterior surface 6b one of the support panels 6 and crimping the third portion 142 of the steel strip 136 to the interior surface 6a one of the support panels 6 using tool to punch, clinch or crimp these surfaces together, as will be described further with reference to
It will be appreciated that the tool tip 150 is driven into an exterior surface of the first and third portions 138, 142 of the steel strips 136 so as to cause plastic deformation of the surfaces of both the first and third portions 138, 142 of the steel strips and the support panels 6 (which may be flat prior to said plastic deformation). As a result of this plastic deformation, the surfaces of the first and third portions 138, 142 of the steel strips 136 are complementary to and in engagement with the exterior and interior surfaces 6b, 6a of the support panel respectively.
The tool tip 150 may be generally cylindrical, having a diameter of the order of 4 to 6 mm. However, as can be best seen in
As can be best seen in
It will be appreciated that the modular partition system can be used to form a partition, with a plurality of adjacent and parallel panels (for example panels 2, 26, 132) connected together using two connecting strips (for example the connecting strips 38, 42, 134) for each pair of adjacent panels. The two connecting strips being provided at opposite ends of the support members 6 of the two adjacent panels.
In general, the support members 6 and connecting strips span between two supports (for example roof beams) and may be manufactured to the desired length (i.e. the dimension of the panels in the y-direction as shown, for example,
The panels may be of any width. The width of the panels may be selected bearing in mind both: the amount of support required for the overall structural stability of the panel and/or the requirements of any substrate which, in use, the panels are intended to support (such as, for example, floorboards, plasterboard etc.). It will be appreciated that it may be desirable for the total assembled width of the modular panel system (i.e. the dimension of the modular system in the x-direction as shown, for example,
In order to allow for a tolerance gap, one or more edging strips may be provided, as now explained. The edging strips may be suitable for engaging with the flange portion of a single panel (in contrast to the connecting strips 33, 40, 42, 134, which are each arranged to engaging with the flange portions of two adjacent panels). Therefore, the edging strips may have a profile shape that is generally of the form of half of one of the connecting strips. This is now explained for the embodiment shown in
The edging strip 154 (which may be formed from rolled steel) is generally of the form of half of the connecting strip 134. The edging strip 154 is generally of the form of a box beam and has an aperture for receipt of: part of the support panel 6 proximate an edge thereof and part of the steel strip 136 proximate the edge of the support panel 6. The edging strip 154 comprises a central wall portion 154a disposed between one generally U-shaped side portion 154b and one generally flat side portion 154c. The channel or groove for receipt of part of the flange of the support members 6 of the single panel 132 is formed between the two side portions 154b, 154c.
The central wall portion 154a has a length that is approximately half that of the central wall portion 134a of the connecting strip 134 (cf.
The edging strip 154 engages with the steel strip 136 in a similar snap fit to that between the connecting strip 134 and the pair of adjacent steel strips 136. The protrusion portion 141 is dimensioned so as to be slightly larger than an opening of the channel or groove formed between the two side portions 154b, 154c. However, the edging strip 154 can resiliently deform sufficiently to allow the protrusion portion 141 to be received in the channel or groove. Once the protrusion portions 141 of the panel 132 has passed the two side portions 154b, 154c, the edging strip 154 can snap back such that the protrusion portion 141 is held captive in the groove or channel.
An embodiment of the invention which relates to a modular partition system for use in a pitched roof is now described with reference to
The hip roof 44 comprises eaves beams 46, each running along the top of a wall 47 to define a perimeter of the hip roof 44, and a ridge beam 48 defining its top edge. The ridge beam 48 is supported by four hip beams 50, which each extends along a diagonal edge of the roof, from an end of the ridge beam 48 to a corner at which two eaves beams 46 meet.
A modular partition system 52 according to an embodiment of the invention is now described with reference to
Generally, on an interior surface of the modular partition system 52, an internal substrate 54 is connected to the panels 2 using one or more fixings (typically screws or nails or the like). The internal substrate 54 may comprise plasterboard, for example 12.5 mm foil backed plasterboard. Each of these fixings passes through a connecting strip 38 and into the flange of one of the panels (i.e. a steel strip 14 and timber batten 16).
Optionally a batten 56 may be provided between the internal substrate 54 and each connecting strip 38. This may be desirable, for example if it is desired to increase the size of the void 58 which is formed between the internal substrate 54 and the insulating panels 4 of the panels 2.
Generally, on an exterior surface of the modular partition system 52, an external substrate or roof structure is connected to the panels 2. There are various different options for such external substrates, as known in the art. In the following, two options are discussed and, from these, it will be apparent to the skilled person how the modular partition system 52 can be used with other types of external substrates. The first option comprises a layer of oriented strand board (OSB) connected to the panels 2 and a layer of roof tiles connected directly thereto. The second option comprises one or more rows of battens (generally extending perpendicular to the fall of the roof) to which roof tiles are connected.
Referring again to
Each section of roof which spans between the ridge beam 48 and one of the eaves beams 46 is generally of the form of the modular partition system 52 shown in
The modular partition system 52 engages with the ridge beam 48 and one of the eaves beams 46 as will now be described with reference to
Engagement between the panels 2 of the modular partition system 52 and the ridge beam 48 is now discussed with reference to
The end support panel 20 may be formed from the same material as the support panels 6. Alternatively, in some embodiments, the end support panel 20 may be formed from a steel strip or sheet. For such embodiments, the portion of the end support panel 20 which extends beyond the protruding portions 8 of the two support panels 6 (so as to form a shoulder 23) may be curved or generally hook shaped so as to better engage with the two side portions 65 of the ridge beam 48.
It will be appreciated that in a ridge roof of the form shown in
The modular partition system 52 provides a particularly versatile and cost effective system for constructing a partition (for example a roof) which provides a number of advantages over the prior art, as now discussed.
The modular partition system 52 provides an alternative to prior art insulated construction panels such as, for example, structurally insulating panels (SIPs). Within an SIP the insulation is sandwiched between two structural panels (i.e. two panels placed on the inside and outside surfaces of the construction panel). SIP panels are not only used for roofs but also generally for construction building walls and floors. Furthermore, SIPs are generally manufactured as large sheet materials that may form an entire, or at least a significant portion of, a partition. This is an intentional feature of prior art SIP systems which is intended to reduce the number of joints in the hope that this will provide less opportunity for air leaks.
Advantageously, the modular partition system 52 uses panels wherein the support members are disposed on the sides of the insulating panels 4 extending generally perpendicularly to a plane of the modular partition system 52. As a result, the modular partition system 52 may use significantly less structural support material than is required for an equivalent SIP panel. As a result, the panels 2 are significantly lighter and are significantly cheaper to produce. In addition, since the support members of the panels 2 extend generally perpendicularly to a plane of the modular partition system 52, there is no need for any load to be transmitted through the insulating panel 4 (in contrast to SIPs). Therefore, any connection (for example adhesive bonding) between the support members and the insulating panel 4 does not need to be of high integrity. In fact, as discussed above with reference to
Furthermore, contrary to the teachings of the prior art, the modular partition system 52 lends itself better to an arrangement with a larger number of panels and, consequently, a larger number of joins. This has been allowed, at least in part, due to the provision of the novel connecting strips 38 arranged to cooperate with a support member from each of two of the plurality of adjacent panels 2 so as to aid a structural connection between two adjacent panels 2. Since the modular partition system 52 allows such smaller panels, it can result in a further cost benefit since the quantity of waste material, for example at apertures in the partition (e.g. doors and windows) and at the joins between partitions (e.g. the corner of a room) can be significantly reduced or even eliminated completely.
In some embodiments, the modular partition system 52 may further comprise a resilient seal between each pair of adjacent panels. For example, a side surface of either or both of the two support members (for example an exterior face of the support panels 6) may be provided with a sealing material (for example a foam tape or the like). Alternatively, a suitable sealing material may be manually provided during installation.
Furthermore, because the modular partition system 52 allows such panels 2, it can be significantly easier to install. For example, it may be easier for the panels 2 of the modular partition system 52 to be manually installed, removing the need for lifting apparatus (e.g. a crane or the like), which can be costly and can lead to costly delays on construction sites (e.g. if the lifting apparatus is temporarily unavailable).
For embodiments wherein the insulation used in the insulating panels 4 is closed cell (for example XPS) there may not be a need for an external (waterproof) membrane to be provided for roofs using the modular partition system 52.
If an external membrane is used with the modular partition system 52 it may be held in place by the connecting strips 38. That is, the external membrane may be applied over two adjacent panels 2 before the connecting strips 33 engage with their support members. Alternatively, an external membrane may be held in place by the steel strips 14 of the panels 2. This is particularly advantageous since the external membrane may be applied at manufacture of the panels 2 saving on installation time.
It will be appreciated that the modular partition system 52 may be provided with a modified connecting strip to allow for site tolerances. For example, due to site tolerances along a run of panels 2 there will be a pair of adjacent panels 2 that have a gap between them. This gap could be filled with expanding foam as is customary and the modified connecting strip may be provided as two separate members with extended legs such that they can overlap each other and be attached together using one or more fixings.
As explained above, at least in some embodiments, one or more rows of battens (generally extending perpendicular to the fall of the roof) are attached to the exterior of the modular partition system 52 to support roof tiles. Therefore, in some embodiments, the connecting strips may be provided with one or more engagement features for engagement with a batten, as now discussed with reference to
On an opposite surface of the connecting strip 40 to said channel or groove is provided a plurality of engagement features for a metal batten. Each engagement feature comprises two pairs of generally L shaped protrusions 80. The protrusions 80 comprise a first portion which extends generally perpendicularly from an upper surface of the connecting strip 40 and a second portion, distal from the upper surface of the connecting strip 40 which extends generally parallel to the upper surface of the connecting strip 40. The second portion of each protrusion 80 defines a guide channel for receipt of a guide flange of a metal batten. Within each pair of protrusions, the second portions extend towards each other such that the guide channels are facing each other. Furthermore, each the guide channels of the two pairs of protrusions are aligned.
As can be seen in
The engagement features may be provided at any convenient separation along the connecting strips 40.
The connecting strips 40 may be formed from a light gauge steel strip. The protrusions may be formed from a portion of the upper surface of the connecting strips 40 which has been partially separated from a main part of the upper surface of the connecting strips 40 (for example by cutting or stamping) and which has been bend out of the plane of the main surface of the connecting strips 40.
On an opposite surface of the connecting strip 40 to said channel or groove is provided a plurality of engagement features for a timber batten 62. Each engagement feature comprises two generally L shaped protrusions 86. The protrusions 86 comprise a first portion which extends generally perpendicularly from an upper surface of the connecting strip 40 and a second portion, distal from the upper surface of the connecting strip 40 which extends generally parallel to the upper surface of the connecting strip 40. The second portion of each protrusion 80 defines a guide channel for receipt of a timber batten 86. The guide channels defined by the two protrusions are aligned.
In use, the connecting strips 40 are installed such that the guide channels defined by the protrusions 86 face generally upwards (for example towards a ridge beam).
As can be seen in
The engagement features may be provided at any convenient separation along the connecting strips 40.
An embodiment of the invention which relates to a modular partition system 90 for use in a cavity wall is now described with reference to
It will be appreciated that the modular partition system 90 shares many features in common with the modular partition system 52 as shown in
As can be seen in
The modular partition system 90 forms the inner leaf of a cavity wall construction. Therefore, on an exterior surface of the modular partition system 90 an external leaf 92 of the cavity wall is provided, a space or cavity being provided therebetween.
The inner leaf of the cavity walls comprises the modular partition system 90, which are supported by the floors 94, 96 as now described with reference to
The panels 2 of the modular partition system 90 which are downstairs are supported by a sole plate 106 which is mechanically anchored to the solid floor 94 (see
In this way the load of the upstairs wall and the lower suspended timber floor 96 is transmitted through the beams 104 and the downstairs wall to the solid floor. For any apertures (for example doors and windows) 98 a lintel 110 is provided to distribute the directly above the aperture 98 to the portions of the wall on either side, in a conventional manner.
It is desirable to mechanically tie the inner and outer leaves of a cavity wall together. Therefore, in some embodiments, the connecting strips on the exterior side of the modular partition system 90 may be provided with one or more engagement features for engagement with a wall tie, as now discussed with reference to
On a flange portion of the connecting strip 40, on two opposite sides of the connecting strip 40 are provided a plurality of features 112 for engaging the ends of a wire wall tie 114. The features 112 may be provided at any convenient separation along the connecting strips 40. During construction, wall ties 114 may be connected to the connecting strip 40 where desired. Subsequently, during construction of the outer leaf brick wall 92, a portion 116 of the wall tie 114 near its distal end is set in the mortar of the brick wall, tying the two leaves together.
The above described panels 2, 26 for a partition comprise an insulating panel 4, i.e. a panel comprising a thermally insulating material, extending between two support panels 6. However, it will be appreciated that in alternative embodiments the insulating panel 4 may be replaced by a material that is not thermally insulating. For example, panels for use internal partitions (either walls or floors), where insulation is not required, may use a cheaper material such as, for example, cardboard. Such embodiments still enjoy many of the benefits discussed above and the cheaper filler material merely provides a connection between the load bearing support members to aid the installation of a partition comprising these panels. As a further alternative, the insulating panels 4 may be replaced with a material with other properties as may be desired for the partition such as, for example, sound insulation. Such an arrangement is shown in
The modified panel 120 is similar in construction to the panels 2, 26 described above although the insulating panel 4 which extends between the two support panels 6 has been replaced by an alternative central panel 122. In this embodiment, the central panel 122 is a composite panel comprising a filler material 124 sandwiched between two sound absorption boards 126. The filler material 124 may comprise mineral wool insulation or another sound absorbing material appropriate. The sound absorption boards 126 are provided with a plurality of through holes to aid sound absorbsion.
As can be best seen in
The connecting strip 121 is generally of the form of connecting strip 38 described above (see
As discussed above, some embodiments of the present invention relate to a modular partition system for forming a partition (for example a thermally insulating or sound insulating partition). In particular, some embodiments of the invention relate to self-supporting structures which can bear a load such as, for example, a roof, a wall or a floor of a building. Generally these embodiments may comprise a plurality of panels (for example the panels 2, 26, 132, 120 described above) and a pair of connecting strips arranged to cooperate with a support member from each of two adjacent panels. The bulk of each panel is non-load bearing in use and provides thermal or sound insulation. The support members of two adjacent panels, along with two connecting strips co-operate to form an I beam.
Some other embodiments of the invention relate to a support beam, as now discussed with reference to
The web panel 162 may comprise an engineered wood. For example, the web panel 162 may comprise a composite material board or panel. For example, the web panel 162 may comprise OSB, hardboard, mdf, chipboard, plywood or the like.
In
The first and second surfaces 168, 170 are both generally rectangular, defined by four edges of the web pan& 162. In particular, first and second edges 172, 174 of the web panel 162 are separated in the z-direction and define a height of the web panel 162. Similarly, it will be appreciated that third and fourth edges of the web panel 162 are separated in the y-direction and define a length of the web panel 162.
It will be appreciated that the dimensions of the web panel 162 may vary for different embodiments. The dimensions may be dependent on the intended use (and load) of the support beam 162. In one embodiment, the web panel 162 may have a thickness of the order of 8 to 12 mm. A height of the web panel (which may be the dimension in the z direction) may of the order of 240 mm.
The first flange 164 is attached to the web panel 162 proximate the first edge 172 of the web panel 162 and the second flange 166 is attached to the web panel 162 proximate to the second edge 174 of the web panel 162. The first and second flanges 164, 166 extend beyond the first and second surfaces 168, 170 of the web panel 162 in a direction generally perpendicular to a plane of the web panel 162.
The first and second flanges 164, 166 are formed from a metal material.
As can be best seen in
In one embodiment, the first and second flanges 164, 166 are formed from sheet metal. For example, the first and second flanges 164, 166 may be formed from a light gauge rolled steel strip, for example, having a thickness of the order of 1 mm. The sheet metal may, for example, be folded or rolled to form the first and second flanges 164, 166. Alternatively, the first and second flanges 164, 166 may be formed using another process, for example a continuous process such as extrusion.
In the present embodiment, the cross sectional profile of the first flange 164 is substantially the same as the cross sectional profile of the second flange 166. This cross sectional profile can be best seen in
In cross section the first and second flanges 164, 166 each comprise a continuous loop of material which extends from the first surface 168 to the second surface 170. In particular, the continuous loop of material comprises a first portion 176 that is in contact with the first surface 168 and a second portion 178 that is in contact with the second surface 170. Extending between the first and second portions 176, 178, the continuous loop or material comprises; a third portion 180 extending generally away from the first surface 168; a fourth portion 182 extending generally parallel to, but spaced apart from the first surface 168; a fifth portion 184 extending generally perpendicularly to a plane of the web panel 168; a sixth portion 186 extending generally parallel to, but spaced apart from the second surface 170; and a seventh portion 188 extending generally between the second and sixth portions 178, 186.
Although the third portion 180 and the fourth portion 182 are generally mutually perpendicular (the third portion 180 extending generally in the x-y plane and the fourth portion 182 extending generally in the z-y plane), the third portion 180 is inclined out of the x-y plane proximate the intersection 181 between the third portion 180 and the fourth portion 182 such that intersection 181 between the third portion 180 and the fourth portion 182 is at an acute angle. Similarly, although the seventh portion 188 and the sixth portion 186 are generally mutually perpendicular (the seventh portion 188 extending generally in the x-y plane and the sixth portion 186 extending generally in the z-y plane), the seventh portion 188 is inclined out of the x-y plane proximate the intersection 187 between the seventh portion 188 and the sixth portion 186 such that intersection 187 between the seventh portion 188 and the sixth portion 186 is at an acute angle.
In this way, the first and second flanges 164, 166 are each of the form of a hollow or tubular structure. This hollow or tubular structure has an opening, groove or channel for receipt of one of the first or second edges 172, 174 of the web panel 162.
Each of the first and second flanges 164, 166 is attached to the first and second surfaces 168, 170 of the web panel 162. This attachment provides resistance to shear forces (the shear plane of the support beam 160 being the plane of the web panel, i.e. the y-z plane). This attachment of the first and second flanges 164, 166 to the first and second surfaces 168, 170 of the web panel 162 prevents movement of the first and second flanges 164, 166 relative to the web panel 162. In some embodiments, the attachment of the first and second flanges 164, 166 to the first and second surfaces 168, 170 is sufficient to resist shear forces of the order of 2.5 kN or more.
It will be appreciated that the attachment of the first and second flanges 164, 166 to the first and second surfaces 168, 170 of the web panel 162 may be achieved in a variety of different ways.
In the present embodiment, the attachment of the first and second flanges 164, 166 to the first and second surfaces 168, 170 of the web panel 162 is via surfaces of the first and second flanges 164, 166 which are complementary to and in engagement with the first or second surfaces 168, 170. In particular, the first portion 176 of each of the first and second flanges 164, 166 is complementary to and in engagement with the first surface 168. Similarly, the second portion 178 of each of the first and second flanges 164, 166 is complementary to and in engagement with the second surface 170.
This engagement is achieved via plastic deformation of the mutually engaging surfaces of the first portions 176 and the first surface 168 (which may be flat prior to said plastic deformation) and plastic deformation of the mutually engaging surfaces of the second portions 178 and the second surface 170 (which may also be flat prior to said plastic deformation). Such plastic deformation may be achieved, for example, by using a punch to crimp the two adjacent surfaces together. For example, a punch may be used to cause the first and second flanges to bite into the web panel.
In particular, the attachment of either of the first and second flanges 164, 166 to the web panel 162 may be achieved in a similar way to the above-described process for the embodiment of the invention shown in
Accordingly, the attachment of either of the first and second flanges 164, 166 to the web panel 162 is achieved by crimping the first portion 176 of the flange 164, 166 to the first surface 168 one of the web panel 162 and crimping the second portion 178 of the flange 164, 166 to the second surface 170 of the web panel 162 using tool to punch, clinch or crimp these surfaces together, at a plurality of positions along the length of the support beam 160. As a result, a plurality of dimples or recesses 190 is visible on the exterior surface of the first and second portions 176, 178 of the first and second flanges 164, 166. Although only the first portions 176 of the flanges 164, 166 are visible in
As explained above with reference to
The tool tip may be generally as described above and may be generally cylindrical, having a diameter of the order of 4 to 6 mm. In one embodiment, the tip of the tool tip tapers to a rectangular edge, being similar in shape to a flat screwdriver. The tool tip may be driven in to a depth of the order of 3 to 4 mm. A distance between the centres of adjacent recesses 190 (formed by tool tip) may be of the order of 40 mm.
As described above with reference to
It will be appreciated that, alternatively, the attachment of the first and second flanges 164, 166 to the first and second surfaces 168, 170 of the web panel 162 may be achieved using screws, nails, rivets or other mechanical fixing.
The fifth portion 184 of each of the first and second flanges 164, 166 may be considered to be a wall portion which is generally perpendicular to a plane of the web panel 162.
The first and second flanges 164, 166 are provided with a feature for engagement with the first or second edge 172, 174 of the web panel 162. In particular, two ridges 192 are formed on the fifth portion 184 of each of the first and second flanges 164, 166. The two ridges 192 provide a location detail for the web panel 162, with is received in a groove formed between the two ridges 192.
The support beam 160 is generally of the form of an I beam. The support beam 160 may be suitable for use as a joist in part of a surface such as a floor, wall or ceiling. The support beam 160 is advantageous over known support beams, as now discussed.
Traditional floor joists are formed from solid timber beams. It has become increasingly common to use an I beam construction for floor joists. One known type of I beam that is used as a floor joist in the construction of buildings comprises a web formed from oriented strand board (OSB) and two solid flanges formed from timber. The OSB web is partially received in a groove in each of the solid timber flanges and attached thereto using adhesive to provide a connection which can resist shear forces.
In contrast to such known I beams or I joists, the support beam 160 described above uses first and second flanges 164, 166 which are formed from a metal material. This offers a significant advantage over the known arrangement since, unlike timber, metal materials may be formed to arbitrary lengths, for example using a range of continuous processes. Therefore, the support beam 160 can be easily manufactured to a range of different lengths. This allows the support beam 160 to be manufactured to the required length for each purpose with substantially no waste.
Furthermore, there are a number of additional advantages of using metal flanges 164, 166 as opposed to timber flanges, including cost, weight and formability.
In addition, the support beam 160 is formed from three parts (the web panel 162, the first flange 164 and the second flange 166), which are attached together (the first and second flanges 164, 166 being attached to the first and second opposed surfaces 168, 170 of the web panel 162). This provides significant advantages over, for example, a typical rolled steel joist (RSJ) which is typically formed entirely from solid steel. This construction, whereby the support beam 160 is formed from three parts which are attached together, advantageously, allows the use of more economical and lighter materials to be used for the web panel 162. Furthermore, it allows the first and second flanges 164, 166 to be formed as generally tubular or hollow structures, providing further cost and weight savings.
It will be appreciated that the shape of the first and second flanges 164, 166 may differ in other embodiments. By way of example,
The support beam 194 comprises a web panel 162, a first flange 196 and a second flange 198. The first and second flanges 196, 198 share a number of features in common with the above described first and second flanges 164, 166.
In cross section the first and second flanges 196, 198 each comprise a continuous loop of material which extends from the first surface 168 to the second surface 170 of the web panel 162. Furthermore, in cross section this continuous loop of material from the first surface 168 to the second surface 170 is generally uniform in cross section. In cross section the first and second flanges 196, 198 are each of the form of a hollow or tubular structure. This hollow or tubular structure has an opening, groove or channel for receipt of one of the first or second edges 172, 174 of the web panel 162.
The first and second flanges 196, 198 may be formed from sheet metal. For example, the first and second flanges 196, 198 may be formed from a light gauge rolled steel strip, for example, having a thickness of the order of 1 mm. The sheet metal may, for example, be folded or rolled to form the first and second flanges 196, 198. Alternatively, the first and second flanges 196, 198 may be formed using another process, for example a continuous process such as extrusion.
The cross sectional profile of the first flange 196 is substantially the same as the cross sectional profile of the second flange 198. However, this cross sectional profile differs from that of the first and second flanges 164, 166 shown in
In cross section the first and second flanges 196, 198 each comprise a continuous loop of material which extends from the first surface 168 to the second surface 170. In particular, the continuous loop of material comprises a first portion 176 that is in contact with the first surface 168 and a second portion 178 that is in contact with the second surface 170. Furthermore, the continuous loop of material comprises a wall portion 184 which is generally perpendicular to a plane of the web panel 162 and which is provided with two ridges 192. However, in this embodiment, the wall portion 184 is connected to the first and second portions 176, 178 by generally straight wall portions 200, 202 respectively.
Extending between the first and second portions 176, 178, the continuous loop or material comprises: a third portion 180 extending generally away from the first surface 168; a fourth portion 182 extending generally parallel to, but spaced apart from the first surface 168; a fifth portion 184 extending generally perpendicularly to a plane of the web panel 168; a sixth portion 186 extending generally parallel to, but spaced apart from the second surface 170; and a seventh portion 188 extending generally between the second and sixth portions 178, 186.
In some embodiments, the support beams 160, 194 may further comprise a resiliently deformable member provided on the wall portion of at least one of the first and second flanges, as now discussed with reference to
In particular, this embodiment further comprises an elongate metal member 204 and an elongate resiliently deformable member 206. The resiliently deformable 206 may comprise a strip of foam material. The elongate metal member 204 may be formed from a light gauge steel strip that is shaped such that it can engage over the first flange 164 using a snap fit type coupling such that the resiliently deformable member 206 is held captive between the elongate metal member 204 and the first flange 164. An internal dimension of the elongate member 204 (in the z-direction) is greater than an external dimension of the first flange 164. Therefore, the elongate member 204 is movably connected to the first flange 164 with the resiliently deformable member 206 being disposed between the elongate metal member 204 and the first flange 164.
It will be appreciated therefore that the shape of elongate metal member 204 will, in general, be dependent on the shape of the flanges of the support beam (for example a different profile of elongate metal member may be used in conjunction with the flanges 196, 198 of the support beam 194 shown in
When a compression force is applied to the central wall section 200, compression of the resiliently deformable member 206 allows the elongate metal member 204 to move towards the first flange 164 in the z-direction.
Such a resiliently deformable member 206 may provide some reduction in the amount of sound that is transmitted through a structure formed using the support beam. For example, the support beam may form a joist for a floor. For example, the resiliently deformable member 206 may be provided on one of the first and second flanges 164, 166 that in use will form a top of the joist (and which may support floorboards or the like). The resiliently deformable member 206 can absorb some sound and therefore at least partially prevent sound from being transmitted through the floor. Advantageously, the embodiment shown in
In some embodiments, the support beams 160, 194 may further comprise one or more engagement features for connection to a resilient bar, as now discussed with reference to
A known and currently used method to prevent sound transmission through an intermediate floor is to screw resilient bars, in the form of a light gauge steel Z-section 214, to the bottom surface of timber floor joists. A ceiling substrate (for example plasterboard) is then attached to the resilient bars 214, which reduce the transmission of sound from the floor to a space below.
As shown in
In some embodiments, the support beams may further comprise one or more hanging features for connection to a supporting structure that is generally perpendicular to the support beam, the one or more hanging features being provided on at least one of the first and second flanges. Sais one or more hanging features may be provided at one or both ends of the support beam (i.e. the two ends which are separated in the y-direction). it will be appreciated that these hanging features may be generally of the form of any known type of joist hanger but which is integrally formed with either or both of the first and second flanges.
Steel joist hangers are used to support the ends of a beam at a supporting structure that is generally perpendicular to the beam (for example a wall or a perpendicular supporting beam). Light gauge steel is used and requires many fixings between the joist hanger and the beam to ensure the structural performance. It is common in construction for installers to not put enough in fixings in (saving time). The one or more hanging features are integrally formed with the support beam and therefore facilitate quick and safe installation.
Some embodiments of the invention may relate to a support beam comprising: a plurality of support beams as described above (for example support beams 160, 194), as now described with reference to
The support beam 218 embodiment further comprises a first elongate connection member 220 arranged to connect to the first flanges 164 of the two support beams 160 as shown in
The first and second connection members 220, 222 are substantially the same and may be formed from a light gauge steel strip that is shaped such that it can engage over the first flanges 164 or the second flanges 166 using a snap fit type coupling. It will be appreciated therefore that the shape of the first and second connection members 220, 222 will, in general, be dependent on the shape of the flanges of the support beam (for example a different profile of elongate metal member may be used in conjunction with the flanges 196, 198 of the support beam 194 shown in
Additional fixings may be provided between the first and second elongate connection members 220, 222 and the first or second flanges 164, 166 of the two support beams 160 as shown in
In the design of an intermediate floor or similar a beam may be required to carry several other beams or joists. The support beam 218 shown in
While specific embodiments of the invention have been described above, it will be appreciated that the invention may be practiced otherwise than as described. The descriptions above are intended to be illustrative, not limiting. Thus it will be apparent to one skilled in the art that modifications may be made to the invention as described without departing from the scope of the claims set out below.
