This invention relates to the construction industry; more particularly, this invention relates to certain building elements useful in construction, especially for the building of internal walls and partitions, although the invention is not necessary limited to this application.
For many years it has been the normal practice in the construction industry to construct internal walls from plasterboard, attached to wooden or metal studs. To install plasterboard walls with an acceptably smooth finish, and to set the joints between adjacent plasterboard panels, it is necessary to employ skilled plasterboard “setters”. This not only increases costs, but influences the building timetable; to achieve maximum efficiency, a building should be prepared to the stage where all plasterboard walls can be installed at one time, so that the setters are on site for the minimum time necessary. A significant cost drawback is the fact that it is unavoidable that this work must be carried out on site.
Once the plasterboard walls have been installed, they need to be sanded before being painted. The sanding procedure creates a significant amount of gypsum dust, with a consequent effect on all articles and material on the site. Moreover, because it is necessary to paint plasterboard, the cost of painting is a significant part of building.
Should it become necessary to repair a plasterboard wall, if a professional finish is required, it is necessary to call in a plasterboard setter and to endure the dust created during the sanding procedure. In addition, it is necessary to repaint the wall after repair.
There is a further problem associated with plasterboard walls, which arises during demolition. Demolition of internal plasterboard walls is frequently necessary in commercial buildings, for example, when a tenant leaves the building. Demolition of plasterboard walls is usually also necessary during refurbishment. Plasterboard walls cannot be dismantled without substantial damage to the plasterboard, to the extent that the plasterboard is not reusable. Even more significantly, substantial gypsum dust is created. It is believed that the inhalation of gypsum dust may have a deleterious effect on health. Consequently, in some jurisdictions, safe work practices require that adjacent areas are evacuated during the demolition of plasterboard walls. This can result in loss of rent for a landlord and interruption of business and loss of profits for a tenant.
After plasterboard walls have been demolished, the plasterboard has a “negative” value in that it is necessary to pay for its removal and disposal. Plasterboard and its framing is not recyclable on an economic basis. It is an aim of the present invention to provide a construction system which can avoid the use of plasterboard panels and hence the difficulty and cost involved in construction, repair and demolition involving plasterboard panels.
It is a further object of this invention to provide a building system which can permit wall panels to be reusable.
It is a further object to provide, in one aspect of the invention, a system which can use wall panels already finished in the factory, so that painting on site is not required.
When wall panels, plasterboard or otherwise, are transported to a building site, damage frequently occurs. In many cases, the damage is relatively minor, and one side of the panel is usable.
It is an object of this invention, in one aspect, to provide a building element which will permit a panel to be erected with either side outermost.
During occupation of buildings, damage is occasionally caused to wall panels. Rather than obtain a replacement panel, it would be desirable to be able to detach the panel and reverse it so that the damaged side is concealed in the wall cavity. This invention, in one aspect, aims to provide that capability.
It is yet a further object of this invention to provide a building system which can be integrated with furniture, especially office furniture, such as work stations.
Accordingly, this invention provides a building element being a stud, characterised in that the stud has a plurality of channels, each channel being adapted to receive a cooperating means for the purpose of mounting a panel or bracket on the stud.
Preferably, the stud has three longitudinal channels, which ideally are set out side by side. Even more preferably, the stud has a first side and a second side opposing the first, and there is one set of three longitudinal channels arranged on the first side and a second set of three longitudinal channels arranged on the second side.
The cross-sectional shape of each channel can be determined by the way in which it is intended to receive the cooperating means. In one preferred embodiment, rather than being “U” shaped, it is preferred that each channel is formed with return rims, so that the channel is “C” shaped in cross-section; however, it is greatly preferred that the base of the channel is flat.
The stud may be manufactured from any suitable material; it has been found that aluminium is acceptable, and has the added advantage that aluminium is recyclable. However, the stud may be made from other materials.
The co-operating means for mounting panels or brackets to the stud is preferably a joining clip, which is also novel.
Consequently, this invention also provides a building element being a joining clip adapted to mount a panel or bracket to the stud of the invention, the joining clip having means for cooperating with a channel of the stud and means for connecting the joining clip to a panel or bracket.
In a preferred embodiment, the joining clip is made of plastic such a polyvinyl chloride (PVC) or other suitable material. If desired, the joining clip may have parts of varying resiliency, formed for example by multi-moulding.
Certain preferred configurations of the cooperating means are illustrated in the accompanying drawings, but the invention is not necessarily limited to these configurations.
As will be seen from the examples in the drawings, the joining clip can perform the function of providing a neat finish to the ends of panels. The clip preferably extends along the length of an edge of each panel for this reason and also to provide maximum strength and stability to the assembled wall.
The means for connecting the clip to a panel may follow, inter alia, either of two methods of construction. In the first method, the panel may be provided with a longitudinal groove in at least one edge (preferably also in the edge opposite the first), in which case the joining clip may have a protrusion, especially a saw-toothed protrusion, which is a push-fit into the groove. This method is illustrated in the drawings. In the second method, the panel end is tapered or shaped to fit within a complementary channel formed in the joining clip. In both cases, it is intended that the material of the clip and the close fit with the panel provides a stable arrangement under normal conditions, but that the use of appropriate force will separate the clip from the panel when required, for example, so that the panel can be reversed.
It is to be understood, however, that it is not an essential part of this invention that the joining clip can be removed from the panel, bracket or the like. In some applications, for example, in wet areas, the panel may be waterproof on one side only and there will be no need to be able to strip the joining piece from the panel.
In addition, the means for connecting the joining clip to a panel may be adhesive, or other suitable means.
In the case of panels around internal or external corners, a new joining element has been devised, which also forms part of the present invention. The joining element of the invention is adapted to annex a first panel to a second panel, and has first means for connecting the joining element to the first panel, second means for connecting the joining element to the second panel and hinge means located between the first and second connection means, the hinge means comprising a resilient bridge.
The connection means may be any of those described in relation to the joining clip, or any other suitable means.
The joining element may also perform the function of providing a neat and functional finish to the ends of panels, like the joining clip. The joining element preferably extends along the length of each panel end for this reason and can also provide maximum strength and stability to the assembled wall.
As indicated, a channel of the stud of the invention may be adapted to receive a cooperating means for the purpose of mounting a bracket, rather than a panel, on the stud. The bracket in turn may serve to connect furniture or panels to the stud, or may be used for other purposes.
Preferably, the bracket to be used in this context takes one of two forms. Both are provided by this invention.
Accordingly, this invention provides in one form a bracket for mounting on the building element, being a stud, of the present invention, the bracket comprising a screw-threaded shaft and a sleeve therefor, the sleeve having at one end a cooperating means adapted to be inserted in a channel of the stud, the channel having first and second ends, wherein the cooperating means is shaped so as to be capable of insertion in the channel at any location between the first and second ends and capable of manipulation to a position where the cooperating means cannot be withdrawn from the channel except at the first or second end, and wherein screwing of the shaft within the sleeve in a direction towards the channel is adapted to lock the bracket in the channel.
Preferably, the channel of the stud is “C” shaped in cross-section, except that it has a flat base. In this context, the cooperating means is preferably generally rectangular in cross-sectional shape, except that one pair of opposing corners of the rectangle are cut off or one corner is rounded off.
The longer dimension of the rectangle complements the width of the base of the channel. The shorter dimension of the rectangle enables the cooperating means to be inserted in the channel between the upstanding arms and flanges forming the channel with the base. Rotation of the cooperating means through 90 degrees, so that the longer dimension of the rectangle lies transversely to the length of the channel prevents withdrawal of the bracket from the channel. The cut-off corners (or the single rounded off corner) of the rectangle permit this rotation to take place. The bracket may then be locked into position in the channel by screwing the shaft in a direction towards the base of the channel.
In another form, this invention provides a bracket for mounting on the building element, being a stud, of the present invention, the bracket comprising a shaft having first and second arms forming an angle between them, the first arm having at one end a cooperating means adapted to be inserted in a channel of the stud, the channel having first and second ends, wherein the cooperating means is shaped so as to be capable of insertion in the channel at any location between the first and second ends and capable of manipulation to a position where the cooperating means cannot be withdrawn from the channel except at the first or second end, and wherein the first arm is adapted to fit substantially within the channel.
With this form of the bracket, it is also preferred that the channel of the stud is “C” shaped in cross-section, except that it has a flat base. In this context, the cooperating means is preferably generally rectangular in cross-sectional shape, except that one corner of the rectangle is rounded off. The longer dimension of the rectangle complements the width of the base of the channel. The shorter dimension of the rectangle enables the cooperating means to be inserted in the channel between the upstanding arms and flanges forming the channel with the base. Rotation of the cooperating means through 90 degrees, so that the longer dimension of the rectangle lies transversely to the length of the channel prevents withdrawal of the bracket from the channel. The rounded off corner of the rectangle permits this rotation to take place. As an alternative to rounding off a corner, a pair of opposing corners may be cut off, as in the case of the first embodiment of the bracket described above.
In order to permit the first arm to lie substantially within the channel, it is preferred that the cooperating means is curved in the longitudinal direction as shown in the drawings. The first arm may also have an O-ring of rubber or other resilient material to assist a tight fit of the first arm in the channel.
When the first arm lies substantially within the channel and a force is exerted on the second arm, in a direction away from the first arm, the bracket in this embodiment locks into the channel.
It will be appreciated that, with either form of the bracket of the invention, items such as furniture may be hung from the stud.
The brackets of the invention have substantial advantages over prior art brackets, because they may be inserted in a channel of the stud at any point along its length, whereas prior art brackets must enter a channel at one end thereof. This creates problems in changing furniture, for example. In addition, using the brackets of the present invention, it is possible to insert new brackets above or below existing brackets without having to remove the existing brackets from the channel. Further, removal of any bracket is a simple task, in contrast to the prior art.
The present invention also provides a ceiling track which may be used in conjunction with the building elements of the present invention. Accordingly, this invention provides a track adapted to be hung from a horizontal surface, the track having a gutter adapted to receive a connecting clip attached to an end of a panel, the track also having a channel adapted to receive a masking clip adapted to conceal the end of the channel.
The horizontal surface may be a ceiling or a beam or joist, for example. The track of the invention may be hung from the horizontal surface by any suitable means, such as by screws, nails or other fixing means.
The connecting clip preferably is shaped to complement the shape of the gutter. The connecting clip may be attached to the end of the panel by any desired method, an example of which is gluing.
The channel adapted to receive the masking clip is preferably shaped so as to provide a good friction fit with the clip.
Preferably, the track of the invention has two gutters and two channels adapted to receive masking clips.
The invention will now be described in connection with the accompanying drawings, in which:

Hinge 46 connects faces 43. Because hinge 46 is resilient, it allows panels 18 to adopt a configuration that is other than 90 degrees. This is useful to form both normal corners and unusual angles; even normal corners are rarely at exactly 90 degrees, and the joining element of the invention accommodates this discrepancy.
In
The lower ends 27 of panels 18 are also covered by masking clips 64, arms 58 of which are a push-fit into channels 56 of track 51. Track 51 is attached to floor 55.
Turning now to
Sleeve 72 has at one end cooperating means 73 and at the other end a flange 76. As may be seen in
As can be seen in
The cross-sectional shape of flange 76 echoes that of cooperating means 73, so that the orientation of cooperating means in channel 12 can be ascertained.
Turning now to
O-ring 86 mounted on arm 81 helps to ensure a snug fit of arm 81 within channel 12 (refer
Cooperating means 84 is generally rectangular in shape, except that one corner is rounded off at 87. The purpose of this is so that cooperating means 84 may be inserted in channel 12 of a stud 10, in a similar manner to cooperating means 73 of bracket 70, then rotated horizontally through 90 degrees with the assistance of rounded off corner 87, trapping bracket 80 in channel 12. Bracket 80 may then be rotated vertically through 90 degrees, so that arm 81 is caused to lie substantially within channel 12, o-ring 86 serving to wedge arm 81 in this position.
It will be appreciated by one skilled in the art that a load placed on arm 82 will enhance the locking of bracket 80 in channel 12.
It will be readily appreciated by one skilled in the art that cooperating means 14 in the embodiment shown in some of the drawings (such as
The building elements, brackets and track of the invention are clearly a substantial advance in the art. The examples referred to herein are illustrative and are not to be regarded as limiting the scope of the invention.
