Conventional construction is mostly conducted in the field at the building job site. People in various trades (e.g., carpenters, electricians, and plumbers) measure, cut, and install material as though each unit were one-of-a-kind. Furthermore, activities performed by the trades are arranged in a linear sequence. The result is a time-consuming process that increases the risk of waste, installation imperfections, and cost overruns. One approach to improving efficiency in building construction may be modular construction. In the case of buildings with multiple dwelling units (e.g., apartments, hotels, student dorms, etc.), entire dwelling units (referred to as modules) may be built off-site in a factory and then trucked to the job site. The modules are then stacked and connected together, generally resulting in a low-rise construction (e.g., between one and six stories). Other modular construction techniques may involve the building of large components of the individual units off-site (e.g., in a factory) and assembling the large components in the field to reduce the overall construction effort at the job site and thereby reducing the overall time of erecting the building. However, shortcomings may exist with known modular building technologies and improvements thereof may be desirable.
Techniques are generally described that include systems and methods relating to building construction and more specifically relating to building assemblies for constructing a building using pre-assembled floor-ceiling panels and walls. The pre-assembled floor-ceiling panels may form part of a diaphragm of the building while one or more of the pre-assembled walls may be coupled to the diaphragm such that they are non-loadbearing.
A building assembly according to some embodiments of the present disclosure may include at least one diaphragm beam having opposite ends connected to an external structural frame of a building, at least one pre-assembled floor-ceiling panel adjacent to a vertical side of and coupled to the diaphragm beam, and at least one pre-assembled wall adjacent to a horizontal side of and coupled to the diaphragm beam. In some embodiments, the diaphragm beam may be filled with a mineral-based material, for example concrete. In some embodiments, the diaphragm beam may include at least one reinforcing member embedded in the mineral-based material. For example, the reinforcing member may be an elongate metal rod (e.g., rebar) which extends along at least a portion of, and in some cases along the full length, of the diaphragm beam. The diaphragm beam may provide support for a diaphragm, which may be constructed using one or more pre-assembled floor-ceiling panel and one or more diaphragm beams, and may thus provide a load path for transmitting load from the diaphragm to an external structural frame of a building. The one or more pre-assembled floor-ceiling panels may each include a plurality of joists extending perpendicular to the diaphragm beam, a floor-panel including at least one metal layer attached to the joists on a floor side of the pre-assembled floor-ceiling panel, and a ceiling panel including at least one layer comprising mineral-based material attached to the joists on a ceiling side of the pre-assembled floor-ceiling panel.
In some embodiments, the ceiling side of the at least one pre-assembled floor-ceiling panel may be above the lower horizontal side of the diaphragm beam. In some embodiments, the floor side of the at least one pre-assembled floor-ceiling panel may be above the upper horizontal side of the diaphragm beam. In some embodiments, the building assembly may include at least two pre-assembled floor panels, each of which is adjacent to an opposite vertical side of the diaphragm beam. Each of the two pre-assembled floor panel may be coupled to an upper horizontal side of the diaphragm beam. In some embodiments, each of the two pre-assembled floor panel may be supported by a horizontally extending bracket attached to the respective vertical side of the diaphragm beam.
In some embodiments, the building assembly may include at least two pre-assembled walls adjacent to opposite horizontal sides of the diaphragm beam. In some embodiments, the at least two pre-assembled walls may be interior walls. In other embodiments, the at least two pre-assembled walls may be envelope walls. In some embodiments, the at least two pre-assembled walls, whether interior or exterior (envelope) walls, may be non-loadbearing walls. As described herein, building or structural loads may be carried by in part by the external structural frame and the diaphragm and not by the walls which define the units or rooms of the building.
In some embodiments, the one or more pre-assembled walls may include a plurality of studs extending perpendicular to the diaphragm beam and a pair of wall panels attached to opposite sides of the studs, brackets attached to an outer side of at least one of the pair of wall panels and configured to support an interior finish layer in a spaced arrangement from the respective outer side, and a sprinkler conduit extending through a cavity defined between the wall panels and protruding beyond the outer side of the at least one of the pair of wall panels to which the brackets are attached. In some embodiments, the pre-assembled wall may include an interior finish layer on each of the outer sides of the pair of wall panels, for example in the case of the pre-assembled wall being an interior or demising wall. The outer sides of the pair of wall panels may define a first distance therebetween, which is narrower than a width of the diaphragm beam, and the interior finish layers may define a second distance therebetween, which is wider than the width of the diaphragm beam and or wider than the distance between the opposing floor panels. In this manner, the finish side of the interior wall may be coupled with the floor side of the floor-ceiling panel in an aesthetically pleasing manner.
In some embodiments, the one or more pre-assembled walls may be non-rigidly coupled to the diaphragm beam, which may avoid or reduce the transference of structural loads to a non-loadbearing wall. In some embodiments, the non-rigid connection between the diaphragm beam and the wall may be achieved using a compressible material and/or a slidable joint between the pre-assembled wall and the diaphragm beam. For example, the diaphragm beam may include at least one bracket extending vertically from a lower horizontal side of the diaphragm beam, the bracket having a slot for forming a non-rigid connection with an upper portion of the pre-assembled wall. In some embodiments, such as in the case of an interior wall, the diaphragm beam may include at least two brackets extending vertically from a lower horizontal side of the diaphragm beam, each of the two brackets arranged to be positioned on opposite sides of the studs of the wall. That is, each of the brackets may be coupled to the diaphragm beam such as to accommodate a stud of the pre-assembled wall therebetween.
In some embodiments, the pre-assembled wall may be a first pre-assembled wall and the building assembly may include a second pre-assembled wall, which is coupled perpendicularly to first pre-assembled wall. The second pre-assembled wall may be an envelope wall (e.g., include exterior cladding material on one side and an interior finish layer on the opposite interior side). This second pre-assembled wall may also include plumbing conduits and may thus be referred to as a utility wall. In some embodiments, two such utility walls may be arranged on opposite sides of an interior or demising wall. The interior or demising wall may extend between the two utility walls, for example through a portion or substantially all of a space defined between two adjacent utility walls, which may improve the acoustic insulation between adjacent units or rooms. The interior wall may include one or more layers of insulation and may be additionally configured to accommodate insulative material in the space between the interior wall and the opposing sides of the two utility walls, which may further improve the acoustic insulation between the units or rooms located on the opposite sides of the demising wall.
In some embodiments, for example when the diaphragm beam is arranged to support an envelope wall, a water-impermeable elongate member may be coupled to the diaphragm beam in a manner to cover the vertical side of the diaphragm beam opposite the vertical side to which the floor-ceiling panel is attached. The water-impermeable member may thus be used to seal the envelope, e.g., by waterproofing and/or thermally sealing the joint between upper and lower exterior or envelope walls. The water-impermeable member may extend substantially along the full length of the diaphragm beam. In some examples, the water-impermeable member may be fabricated as an extrusion or a pultrusion formed of a plastic or composite material (e.g., a fiber reinforced plastic (FRP)). In some embodiments, the elongate member may cover at least a portion of the upper and/or lower horizontal sides of the diaphragm beam. In some embodiments, the elongate member may include a vertically extending flange configured to be received between an exterior cladding layer and a stud of the pre-assembled wall. In some embodiments, the elongate member may be coupled to the diaphragm beam such that it defines a cavity between the elongate member. The cavity may provide thermal insulation. For example, the cavity may contain a thermally-insulative material such as semi-rigid mineral wool, a thermal blanket material or the like.
A building assembly in accordance with further embodiments of the present disclosure may include a pair of diaphragm beams, each filled with a mineral-based material and each having opposite ends connected to an external structural frame of a building, a pre-assembled floor-ceiling panel arranged between and coupled to the pair of diaphragm beams, a first pre-assembled wall coupled to a horizontal side of one of the first and second diaphragm beams, wherein the first pre-assembled wall is an interior wall of the building, and a second pre-assembled wall coupled to a horizontal side of the other one of the first and second diaphragm beams, wherein the second pre-assembled wall is an envelope wall of the building. In some embodiments of the building assembly, the pre-assembled floor-ceiling panel may be one of a plurality of pre-assembled floor-ceiling panels extending between the first and second pre-assembled walls. In some embodiments, the building assembly may further include another pre-assembled wall connecting the first and second pre-assembled walls and which includes one or more plumbing conduits. In yet further embodiments, the pair of diaphragm beams may be a first pair of diaphragm beams and the building assembly may include at least one second pair of diaphragm beams coupled to the external structural frame at a vertical location above the first and second pre-assembled walls, for example to define another story of the building. In some such embodiments, the pre-assembled utility wall may be tall enough to span more than a singly story, e.g., it may extend from below the first pair of diaphragm beams to above the second pair of diaphragm beams.
The foregoing summary is illustrative only and is not intended to be in any way limiting. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features will become apparent by reference to the drawings and the following detailed description.
The foregoing and other features of the present disclosure will become more fully apparent from the following description and appended claims, taken in conjunction with the accompanying drawings. Understanding that these drawings depict only several embodiments in accordance with the disclosure and are, therefore, not to be considered limiting of its scope, the disclosure will be described with additional specificity and detail through use of the accompanying drawings, in which:
all arranged in accordance with at least some examples of the present disclosure.
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are implicitly contemplated herein.
This disclosure is drawn, inter alia, to methods, systems, products, devices, and/or apparatus generally related to pre-assembled panels (e.g., pre-assembled floor-ceiling panels, pre-assembled walls) for use in a building and to building systems which include a diaphragm provided by one or more pre-assembled floor-ceiling panels and in which vertically extending pre-assembled walls may be coupled to the diaphragm to define the envelope of the building and/or divide the interior of the building into units (e.g., a dwelling or commercial unit or a room within such dwelling or commercial unit). A building assemblies according to the present disclosure may be a single building components, such as a pre-assembled panel, or an assembly of a plurality of components (e.g., beams and/or panels), not necessarily a fully assembled building.
In some examples, the pre-assembled panels may be assembled off-site in a shop and then transported to the building site for assembly into the building system. At the building site, the pre-assembled panels may be attached directly or indirectly to a building frame. The building frame may be an external frame. The term external frame, also referred to as external structural frame, will be understood to refer to a structural frame of a building which is arranged generally externally to the envelope of the building. This is, in contrast to other types of structural frames that include vertical and horizontal load bearing members located within the perimeter defined by the building envelope, as is typical in timber construction for example, the external frame is arranged outside the perimeter of the building envelope. As is generally known in the field of structural engineering, the structural frame is the load-resisting or loadbearing system of a building which transfers loads (e.g., vertical and lateral loads) into the foundation of the building trough interconnected structural components (e.g., load bearing members, such as beams, columns, loadbearing walk, etc.). The design and construction of a building with an external frame may have advantages over internally framed buildings but may also bring new challenges, some of which may be addressed by examples of the present disclosure.
For example, building regulations in countries around the world impose requirements for the design and construction of buildings to ensure the safety to occupants of the building. In many countries, these regulations (also referred to as building codes), require that a building be designed and constructed such that, for example in case of a fire, the stability of the building (e.g., its load bearing capacity) is maintained for a reasonable period of time (e.g., a time sufficient to allow the occupants to egress the building). Therefore, typically, building codes in many countries impose fire proofing requirements to any load bearing structure (e.g., vertical and horizontal load bearing members). Modern steel framed buildings are sometimes constructed with external structural frames, i.e., where the structural frame on the outside of the façade, that is external to the building's envelope. In the event of a fire, an external structural frame may thus be heated only by flames emanating from windows or other openings in the building façade and the fire exposure to the external steelwork may thus be much less severe as compared to what the steel inside the building experiences. In some such cases, and depending on the design of the building and frame, the external frame, or at least some components thereof, may not need to be fire-proofed as is generally required any steel frame members located within the interior to the building, which may reduce material (e.g., spray on fire resistive materials and/or intumescent paint) and/or construction costs.
The diaphragm of a building system in accordance with some embodiments of the present disclosure may be provided by one or more, and typically a plurality, of pre-assembled floor-ceiling panels. The use of pre-assembled floor-ceiling panels may obviate the need for using concrete slab construction as is typically done, e.g., in mid- and high-rise construction. That is, in examples of the present disclosure, the diaphragm, which may provide a floor system of a building such as building 101 discussed further below, may be constructed from pre-assembled floor panels without the use of a concrete slab, which may further improve the cost/efficiency of erecting the building by removing a step in a conventional building construction process (e.g., the concrete slab pouring/curing step). Additionally, the pre-assembled floor-ceiling panels may be arranged in a manner that reduces the overall use of structural steel needed to support and transfer loads from the diaphragm to the external frame and consequently may reduce cost for erecting and generally conforming the building to code (e.g., fireproofing structural steel). Pre-assembled panels for use in a diaphragm according to the present disclosure may define part of or the whole of a floor and part of or the whole of a ceiling in the building, such as part of or the whole of a floor and ceiling of a building unit. Thus, in some examples, such pre-assembled panel may interchangeably be referred to herein as a floor and ceiling panel, a floor-ceiling panel, or a floor ceiling sandwich (ITS) panel. The floor may be a portion of a story of the building above the panel, and the ceiling may be a portion of a story of the building below the panel.
The pre-assembled panel(s) used in a diaphragm according to some embodiments may include a floor-panel frame, a floor panel, and a ceiling panel. The floor and ceiling panels may be spaced from one another by the floor-panel frame. The floor-panel frame may separate the floor panel from the ceiling panel. The floor-panel frame may include a plurality of joists positioned between the floor panel and the ceiling panel. The floor-panel frame may define one or more joist cavities between adjacent joists. In some examples, the one or more joist cavities may accommodate plumbing, cabling, wiring, or other conduits or other elements that may support dwelling or commercial units in the buildings. An insulative material may be located in the one or more joist cavities. In some examples, cross members may be provided in or operatively arranged relative to the one or more joist cavities, for example for increasing the lateral stability of the panel. In some examples, the cross members may be implemented in the form of straps, such as metal straps, connected between opposite corners of a joist cavity. Sound dampener material (also referred to as sound insulative material) may be positioned between the floor-panel frame, the floor panel, and the ceiling panel to reduce sound transmission through the floor and ceiling panel.
The floor panel may be attached to an upper side of the frame, also referred to as floor side of the frame. The floor panel may support a floor material (e.g., a floor finish such as tile, hardwood, manufactured wood, laminate or others) of an upper story. The floor panel may be formed of one or more layers of non-combustible material and may include a radiant heating element. The ceiling panel may be formed of one or more layers of non-combustible materials and may be attached to a lower side of the frame, also referred to as ceiling side of the frame. The ceiling panel may support a ceiling material (e.g., a ceiling finish such as ceiling tiles or other type of finish as may be desired) of a lower story. In some embodiments, the floor-ceiling panels may be implemented in accordance with any of the examples described in co-pending international patent application PCT/US17/21168, titled “Floor and Ceiling Panel for Slab-free Floor System of a Building,” which application is incorporated is incorporated herein by reference in its entirety for any purpose.
A pre-assembled wall used in a building assembly according to some embodiments herein may include an interior or demising wall or an exterior or envelope wall. The pre-assembled wall may be pre-assembled (in a factory) to include some or all of the conduits, insulation, and other components typically provided between the wall finish materials in conventional construction, such as any components as may be desired or need to support use of the building unit. In some embodiments, the pre-assembled wall may be pre-assembled to include one or more of the plumbing conduits (e.g., water and sewer pipes) needed to supply plumbing services to the unit. Such pre-assembled walls may be interchangeably referred to as utility walls. In some embodiments, a pre-assembled wall according to some embodiments herein may include a wall-panel frame including a plurality of studs, wall-boards disposed on opposite sides of the studs and defining a wall cavity, and finish materials attached to each side of the wall. For an interior wall, interior finish panels may be pre-assembled to the wall, one or more of which may be removable temporarily for installation of the wall. For exterior walls, one side of the wall may be pre-assembled to include interior finish panels and the other side of the wall may be pre-assembled to include exterior finish materials (also referred to as cladding).
In some embodiments, the material composition of the floor-panel and/or the wall-panel frame may be predominantly metal, for example and without limitation aluminum, steel, or alloys thereof. In some embodiments it may be predominately aluminum. In still other embodiments, floor-ceiling panel components (e.g., floor panels, ceiling panels, and/or floor finish materials) and wall components (e.g., wall-boards and/or or interior and exterior finish layers) may be made from a variety of building suitable materials comprising metals, to wood and wood polymer composites (WPC), wood based products (lignin), other organic building materials (bamboo) to organic polymers (plastics), to hybrid materials, or earthen materials such as ceramics. In some embodiments cement or other pourable or moldable building materials may also be used. In other embodiments, any combination of suitable building material may be combined by using one building material for some elements of the panel and other building materials for other elements of the panel. Selection of any material may be made from a reference of material options (such as those provided for in the International Building Code), or selected based on the knowledge of those of ordinary skill in the art when determining load bearing requirements for the structures to be built. Larger and/or taller structures may have greater physical strength requirements than smaller and/or shorter buildings. Adjustments in building materials to accommodate size of structure, load and environmental stresses can determine optimal economical choices of building materials used for all components in the system described herein. Availability of various building materials in different parts of the world may also affect selection of materials for building the panel described herein. Adoption of the International Building Code or similar code may also affect choice of materials.
Any reference herein to “metal” includes any construction grade metals or metal alloys as may be suitable for fabrication and/or construction of the system and components described herein. Any reference to “wood” includes wood, wood laminated products, wood pressed products, wood polymer composites (WPCs), bamboo or bamboo related products, lignin products and any plant derived product, whether chemically treated, refined, processed or simply harvested from a plant. Any reference herein to “concrete” includes any construction grade curable composite that includes cement, water, and a granular aggregate. Granular aggregates may include sand, gravel, polymers, ash and/or other minerals.
In referring now to the drawings, repeating units of the same kind or generally fungible kind, are designated by the part number and a letter (e.g. 214n), where the letters “a”, “b” and so on refer to a discrete number of the repeating items. General reference to the part number followed by the letter “n” indicates there is no predetermined or established limit to the number of items intended. The parts are listed as “a-n” referring to starting at “a” and ending at any desired number “n”.
The building 101 may include two or more stories or levels 103. The envelope of the building 101 may be defined by exterior walls and windows, e.g., by end walls 108, window panels 104, which may include floor to ceiling window panels defining a window wall, and/or utility walls (not shown in this view). These walls may be referred to as the building's exterior or envelope walls. The interior of the building 101 may be divided into one or more dwelling or commercial units 105 and/or one or more rooms of a unit using interior walls, also referred to as demising walls 106. In embodiments of the present disclosure, the various walls (e.g., demising walls 106, end walls 108, and window walls) of the building 101 may not be load bearing walls. Rather, loads may be transferred to and carried by the external structural frame 110. Loads (e.g., lateral loads from wind and/or earthquakes) may be transferred to the external structural frame 110 via the diaphragm 120, as will be further described.
The building 101 may be classified as a low-rise, mid-rise, or high-rise construction depending on the number of stories (each city or zoning authority may define building heights in any fashion they deem proper). The building 101 may include, as part of the diaphragm 120, one or more floor-ceiling panels 122. A floor-ceiling panel as described herein may be suitable for use in a building of any number of stories (levels), including a mid-rise building and a high-rise building. In some embodiments, the building may be a residential multi-dwelling building having six, seven, eight or more stories, and in some example twenty five, thirty five, fourth five, or more stories (e.g., as in high-rise or skyscraper construction).
As shown and described, the building 101 may include an external structural frame 110. The external frame 110 may serve as a structural exoskeleton of the building 101. The external frame 110 may include multiple columns 112 (also referred to as frame columns), beams 114 (also referred to as frame beams), and/or cross braces 116. The columns 112 are oriented vertically, the beams 114 are oriented horizontally, and the cross braces 116 may be oriented horizontally or obliquely to the columns 112. For example cross braces may be horizontally oriented (e.g., as the frame beams 114) connecting adjacent columns, or they may be obliquely oriented to the columns and/or beams, e.g., as the cross-braces 116 illustrated in the example in
The building 101 may include multiple units or modules 105 disposed internally of the external frame 110. The units 105 may be commercial, residential (such as dwelling units), or a combination thereof (e.g., live-work units). The units may be standardized and repetitive, or unique and individualized. Mixed units of standard size and shape may be combined with unique units in the same floor, or in independent arrangement on separate floors. In some embodiments, a unit may encompass more than one floor. The units 105 may be assembled at the building site using multiple pre-assembled or pre-assembled components (e.g., pre-assembled floor-ceiling panels 122, prefabricated walls, etc.). The pre-assembled components may be assembled independent of one another remotely from the building site and transported to the building site for installation. The pre-assembled components may include, as delivered to the building site, most or all of the components to support the commercial or residential use of the units, e.g., electrical and/or plumbing conduits, heating and air conditioning ducting, etc. Thus, installation of sub-systems in the field may be reduced, thus again reducing the overall cost and construction timeline. The pre-assembled components may be attached to the external frame 110, to adjacent components, or both at the building site to erect the building 101 and form the individual units 105. In some embodiments, the building 101 may include internal support (e.g., loadbearing) structures. For example, the diaphragm 120 may include one or more support beams (see e.g., transverse beams 230 in
Pre-assembled components according to the present disclosure may include one or more pre-assembled or pre-assembled floor-ceiling panels 122 and one or more pre-assembled or pre-assembled walls (e.g., demising wall 106, end wall 108). The floor-ceiling panels 122 are oriented substantially horizontally to define the floor of an upper unit and the ceiling of a lower unit. Individual floor-ceiling panels 122 may be arranged horizontally and adjacent to one another along their longitudinal direction. The longitudinal direction may be the direction of longer length of a rectangular panel. The longitudinal direction may be the direction along which the joists run. The transverse direction may be direction of shorter length of a rectangular panel, i.e., the direction perpendicular to the longitudinal direction. The longitudinal and transverse directions refer to the planform shape of the panel, each panel also having a thickness direction which is perpendicular to the longitudinal and transverse directions. In some examples, the panels may be generally square in shape in which case the longitudinal direction may be the direction along which the joists run. Individual floor-ceiling panels 122 may be attached to one another, one or more columns, one or more beams, or any combination thereof. The individual floor-ceiling panels 122 may be coupled to and supported by diaphragm beams, which in turn may be coupled to the external frame, such as via a coupling between a respective diaphragm beam and one or more beams 112 and/or columns 114 of the external frame 110 to transfer loads from the diaphragm 120 to the external frame 110. The walls (e.g., demising walls 106 and end walls 108) may be oriented substantially vertically to define the envelope of the building and/or partition each story into multiple units, a single unit into multiple rooms, or combinations thereof. The walls may be attached to the floor-ceiling panels 112 with fasteners and then caulked, sealed, or both. In some embodiments, some of the walls of building 101 may additionally or alternatively be attached to the diaphragm beams that support the floor-ceiling panels 112.
The floor system 202 may be part of a multi-story building (e.g., building 101 in
In the case of an external frame, the columns 212 (e.g., columns 212-1, 212-2, 212-3, and 212-4) may be arranged around the perimeter of the building. The beams 114 may connect adjacent columns and the columns and beams 212, 214, respectively, of the structural frame 210 may define, when viewed in plan as shown in
In the illustrated example in
Referring now further to
To assemble the panels 222 into the diaphragm 220, the panels 222 may be supported by diaphragm beams 230 along their transverse edges. In some embodiments, the panels 222 may be supported only along their transverse edges. In some examples, each panel may include one or more second mounting components (e.g., one or more angle or L-shaped brackets) which may be rested against and joined (e.g., mechanically fastened, welded or otherwise joined) to a diaphragm beam 230. For example, the lateral edges 262-1 of the panels 222 may be joined to diaphragm beam 230-1 and the opposite lateral edges 262-2 of the panels 222 may be joined to another diaphragm beam 230-2. The diaphragm beam 230-1 may be arranged near and extend between end columns 212-1a and 212-1b. The diaphragm beam 230-2 may be arranged to extend between columns 212-2a and 212-2b. The diaphragm beams 230 may be joined to the external frame and may thereby transfer load from the diaphragm to the frame. For example, opposite ends of the diaphragm beam 230-1 may be joined to each of the pair of frame beams 212-2a and 214-22b. In other embodiments, the diaphragm beam 230-1 may be joined to directly to the columns or another component of the external frame. In some embodiments, the diaphragm beam 230-1 may be adjacent to (e.g., parallel to) a frame beam 214-1a that connects the end columns 212-1a and 212-1b. While the diaphragm beam 230-1 may be fire-rated, the frame beam 214-1a may or may not be fire-rated. The term fire-rated in the context herein is generally used to imply that the component is configured to meet the relevant fire code. In some examples, both of the adjacent beams (e.g., the diaphragm beam 230-1 and the frame beam 214-1) may be configured such that they meet the fire code. In some embodiments, the diaphragm beams (e.g., beams 230-1, 230-2) may be filled with a mineral-based material such as concrete (see e.g.,
In some embodiments, the diaphragm beam 230-2 supporting the opposite transverse edges of the floor-ceiling panels may be joined directly to the columns 212-2a and 212-22b (e.g., as shown in
The diaphragm may not be joined to a load bearing member along its longitudinal edges 221-1 and 221-2. Rather all loads from the diaphragm may be transferred to the external frame via the diaphragm beams 230, e.g., via the coupling assemblies 240 between the diaphragm beams 230 and the external frame 210, for example by following the load path diagrammatically illustrated by arrows A-C. As shown, load may be transferred along the diaphragm towards the transverse edges 262-1, 262-2 of the panels 222 as shown by arrows A. The load may be transferred to the diaphragm beams 230 (e.g., by the joints between the floor-ceiling panels and the diaphragm beams) and may then be transmitted along the diaphragm beams 230 toward the external frame 210 as shown by arrows B. The load may be transmitted from the diaphragm 220 to the external frame 210 via the coupling assemblies 240 between the diaphragm beams 230 and the external frame 210. For example, load may be transmitted to the beams (e.g., beams 214-2a and 214-2b) and then the columns (e.g., columns 212-1a and 212-1b), as shown by arrows C, or directly to a column (e.g., columns 212-2a, 212-2b) of the external frame 210, which then transfer the load to the foundation.
As illustrated, the panels 222 that form part of the diaphragm are not directly joined to the structural frame along at least one longitudinal edge (also referred to as unsupported longitudinal edge) and thus no load is transferred to the structural frame trough the interface of any other building components arranged along the unsupported longitudinal edge. Rather structural loads are transmitted from the panels to the diaphragm beams (e.g., via the internal structure of each panel such as the joists) and then the load is transmitted to the external frame via the coupling assemblies 240. In this regard, the panels 222 may be said to be unsupported along at least one of their longitudinal edges. In some embodiments, non-loadbearing walls may be joined to the floor-ceiling planes 222 along the longitudinal unsupported edges, such as a window wall or a utility wall. In some embodiments, one or more of the non-load bearing walls (e.g., end wall 108, window walls, utility walls) may be continuous walls that span the full distance between two columns of the external frame. For example, in the illustrated embodiment in
The individual layers of the floor panel 226 and the ceiling panel 228 may be formed using discrete (e.g., separable) pre-manufactured construction elements (e.g., boards of non-combustible materials, such as cement board, magnesium oxide (MgO) board, fiber-cement board, gypsum board, fiberglass-clad cement or gypsum board, metal-clad cement or MgO board, and other suitable mineral-based materials), which may be joined to the floor-panel frame 224 off-site (e.g., in a factory or other location remote) prior to delivery of the floor-ceiling panels 222 to the building site, thus reducing on-site construction time/costs. The floor panel 226 may include at least one layer 225 made substantially from non-combustible material (e.g., cement board, magnesium oxide (MgO) board, etc.) and at least one metal diaphragm layer 213 (e.g., a sheet of steel such as a 22 gage steel sheet or another). The metal diaphragm layer 229 may be attached to (e.g., bonded or mechanically fastened) the non-combustible material and/or to the floor-panel frame 224. In some embodiments, the metal diaphragm layer may be simply sandwiched between layers of the floor panel 226 and/or the floor-panel frame 224 (e.g., between a layer of non-combustible material and the frame or between two layers of non-combustible material) without being otherwise attached thereto. In some embodiments, the floor panel 226 may include a radiant heating element 219, which may be provided in a layer (e.g., foam or other type of insulative layer 227) of the floor panel 226. The ceiling panel 228 may include at least one layer (e.g., layers 228-1, 228-2) made substantially from non-combustible material (e.g., cement board, magnesium oxide (MgO) board, fiber-cement board, gypsum board, fiberglass-clad cement or gypsum board, metal-clad cement or MgO board, and other suitable mineral-based materials).
In some embodiments, the panel frame 224 (e.g., joists 215) may be formed of metal, such as aluminum or steel. In some embodiments, the panel frame 224 may be formed of a non-metallic material, such as wood, plastic, or composite materials such as fiber reinforced composites. In the illustrated example, the joists 215 are implemented using metal C-channels, e.g., of lightweight steel as manufactured by Steelform Building Products Inc. (marketed under the name Mega Joist). A variety of other types of joists, for example and without limitation I-shaped, or closed, box shaped joists may be used in other embodiments. The insulation 217 provided in the panel 222 may include thermal and/or sound insulation. For example, sound dampening materials (e.g., sound strips) may be provided between the individual layers of the floor panel 226 and the ceiling panel 228 and/or between these panels and the frame (e.g., between the panels and the joist). The floor-ceiling panels 222 may define a generally enclosed space by the floor-panel frame 224 and the floor and ceiling panels 226, 228, respectively. Mounting components (e.g., angles, angle clips, L-shaped or C-shaped brackets, or brackets of other types or geometries) may be joined to the floor-panel frame 224 along the longitudinal and transverse edges of the panel 222 for joining each panel to an adjacent panel and/or to a diaphragm beam.
As described, a building assembly according to some embodiments of the present disclosure may include at least one diaphragm beam (e.g., diaphragm beam 230-1, 230-2) having opposite ends connected to an external structural frame (e.g., frame 210) of a building. The building assembly may further include at least one pre-assembled floor-ceiling panel (e.g., panel 222) adjacent to a vertical side of and coupled to the diaphragm beam, and at least one pre-assembled wall (e.g., a demising wall 106, an end wall 108, or a utility wall) which is adjacent to a horizontal side of and coupled to the diaphragm beam. In some embodiments, building assemblies according to the present disclosure may be used to implement one or more interfaces of or joints joining horizontally adjacent floor-ceiling panels and one or more interior or demising walls to a diaphragm beam, e.g., as shown and described with reference to
The building assembly 400 may include a diaphragm beam 230-2, which in some embodiments may be filled with a mineral-based material 405, e.g., concrete, and/or other type of non-combustible or fire-resistant material. The diaphragm beam 230-2 may be implemented using an elongate, closed cross-section member 403, such as a steel, hollow structural section (HSS) beam, and which encloses the mineral-based material 405 or other type of non-combustible or fire-resistant material. Filling the interior of the diaphragm beams with a mineral-based or other type of non-combustible or fire-resistant material may enable the beam meet fire code, and thus obviate the need to use other types of fire resistant treatments (e.g., intumescent paint, spray on insulation, etc.), which may be more costly or more time consuming to install. The filling of the diaphragm beam with a mineral-based material 405 may additionally provide improved load-carrying capability which may enable the construction of a diaphragm that is not supported by beams along at least some edges (e.g., the longitudinal edges) of the diaphragm. In some embodiments, the diaphragm beam 230-2 may include an at least one reinforcing member 407 embedded in the mineral-based material 405. For example, the reinforcing member(s) may include one or more elongate metal rods (e.g., rebar) which extend along at least a portion of, and in some cases along the full length, of the diaphragm beam 230-2. The closed cross-section member 403 may include upper and lower horizontal sides 408-1, 408-2, respectively, and opposite vertical sides 409-1 and 409-2.
The building assembly 400 may be used to implement the joint between two horizontally adjacent floor-ceiling panels (e.g., floor-ceiling panel 222-a and 222-b), a diaphragm beam (e.g., diaphragm beam 230-2), and one or more interior (i.e., demising) walls (e.g., walls 406-a and 406-b). Each of the floor-ceiling panels 222-a, 222-b may be implemented in accordance with any of the examples of pre-assembled floor-ceiling panels herein. For example, each of the floor-ceiling panels 222-a, 222-b may include a floor panel 226-a, 226-b, respectively, and a ceiling panel 228-a, 228-b, respectively, coupled to opposite sides of a panel frame that include a plurality of joists (e.g., joist 215-a and 215-b of panels 222-a and 222-b, respectively). The floor panels may define a floor side of a story or level of a building (e.g. an upper story of building 101) and the ceiling panels may define a ceiling side of a story or level immediately below the upper story.
Each of the panels 222-a, 222-b is adjacent to a vertical side 409-1, 409-2, respectively, of the diaphragm beam 230-2. In some examples, the panels 222-a, 222-b may be directly against (i.e., abutting) the respective vertical side of the beam 230-2. In other example, the panels 222-a, 222-b may be adjacent to but spaced from the respective vertical side of the beam 230-2, such as to accommodate additional layers 404 of material therebetween. For example, the additional layers 404 may include a thermally insulative material and/or a fire-resistant material, which may be sandwiched between the respective panel 222-a, 222-b and the respective vertical side of the beam 230-2. In some embodiments, the additional layers of material may be pre-assembled (e.g., fastened, bonded or otherwise attached) to the diaphragm beam 230-2 at the factory prior to delivery and assembly of the diaphragm beam to the building frame.
To assemble the floor-ceiling panel 222-a, for example, to the diaphragm beam 230-2, the panel 222-a may be positioned adjacent to the vertical side 409-1 of beam 230-2 and may then be coupled to the beam 230-2, for example by welding or mechanically fastening the panel 222-a to the beam 230-2. To that end, the panel 222-a may include a connector bracket 270-a, which may be implemented using one or more angle brackets (e.g., a L-shaped or T-shaped bracket), or differently-shaped brackets that extend continuously or discontinuously along some or substantially the full transverse edge of the panel 222-a, with one of the legs of the bracket extending outwardly from the panel's edge. The beam 230-2 may be pre-assembled or provided at the building site with a support bracket 232. The support bracket 232 may be implemented using one or more angle bracket (e.g., an L-shaped or T-shaped bracket), or differently-shaped bracket that extend continuously or discontinuously along some or substantially the full length of the beam 230-2, with one of the legs of the bracket extending outwardly from (e.g., perpendicularly to) the vertical side 409-1 of the beam. The beam 230-2 may be provide with support brackets 232 on both of the opposite vertical sides of the beam 230-2 so as to support a respective floor-ceiling panel at each of its vertical sides. The panel 222-a may be arranged with respect to the beam such that the bottom side of the panel 222-a (e.g., ceiling side prior to assembling a ceiling finish material thereto) rests on the support bracket 232 and such that the connector bracket 270-a of the panel 222-a rests on the upper horizontal side of the beam 230-2. The panel 222-a may then be joined to the beam 230-2, for example by fastening the outwardly (i.e., horizontally) extending portion of the support bracket 232 to the ceiling panel and/or panel frame of floor-ceiling panel 222-a and also by coupling (e.g., by fastening or welding) the outwardly extending portion of the connector bracket 270-a to the beam's upper horizontal side 408-1. It will be understood that a similar process may be performed to join the other floor-ceiling panel 222-b at the opposite vertical side of beam 230-2. As will be further understood, a floor system for each unit or room located on the opposite sides of beam 230-2 may be formed using a plurality of floor-ceiling panels (e.g., as shown and described with reference to
In some embodiments, e.g., to accommodate coupling the floor-ceiling panels in the manner described, the ceiling sides of the floor-ceiling panels 222-a, 222-b may be above the lower horizontal side 408-2 of the diaphragm beam 230-2. In such embodiment, the support bracket may have a leg that is joined (e.g., welded to the vertical side of the beam and forming a ledge above the lower horizontal side 408-2 of the beam. In other embodiments, the ceiling sides of the floor-ceiling panels 222-a, 222-b may be substantially in line with the lower horizontal side 408-2 of the beam. In such examples, the L-shaped bracket may have a leg that extends outward from the beam and is substantially aligned with the lower horizontal side of the beam, and a leg that is attached to the vertical side of the beam and extend vertically upward from the other let. Other arrangements may be used, such as coupling the support bracket at any other location along the vertical sides of the beam and/or to the lower horizontal side of the beam.
In some embodiments, the floor side of the pre-assembled floor-ceiling panels may be substantially in line or, in some example, above the upper horizontal side 408-1 of the diaphragm beam. In the case of the latter, the connector brackets 270-a, 270-b of the respective floor-ceiling panels 222-a, 222-b are attached to the transverse edge of the panels at a location below the upper or ceiling side of each panel. Thus when the panels 222-a, 222-b are rested onto the upper horizontal side 408-1 of the diaphragm beam 230-2, the ceiling side of the respective panel 222-a, 222-b is at least slightly above the upper horizontal side 408-1 of the diaphragm beam 230-2. In some embodiments, the connector brackets 270-a, 270-b are arranged such that the floor panel is substantially the only portion of the floor-ceiling panels that extends vertically above the upper horizontal side 408-1. This arrangement of components may increase the ease of aligning and/or coupling wall panels into the assembly, e.g., by defining a track between the horizontally adjacent panels for receiving a demising wall (e.g., wall 406-a).
In some embodiments, the building assembly may include at least two pre-assembled walls adjacent to opposite horizontal sides of the diaphragm beam. As shown in
In some embodiments, for example as illustrated in
For example, and referring to
When installing the upper diaphragm, an upper diaphragm beam (e.g., beam 230-2) may be positioned over the demising wall 406-b such that the brackets 401 engage the upper portion of the demising wall 406-b. The distance between the brackets 401 may be selected to accommodate at least part of the upper portion of the demising wall 406-b therebetween, in this example accommodating the wall-frame and layers 305 therebetween. That is, each of the brackets 401 may be positioned relative to the diaphragm bean and coupled thereto such as to accommodate at least the studs of the pre-assembled wall therebetween. In some cases, a shim may be inserted between the brackets and the demising wall portion that is sandwiched between the brackets 401. Each bracket 401 may be provided with a slot and a fastener may be received through the slot joining the bracket 401, and thus the beam 230-2, to the demising wall 406-b while still enabling the demising wall to displace vertically with respect to the beam 230-2 (i.e., by movement of the fasteners in the slots). Additionally and optionally a non-rigid material, such as semi-rigid insulation or a compliant material, may be provided between the opposing surfaces of the demising wall 406-b and the diaphragm beam 230-2. In other embodiments, the non-rigid connection may instead be provided at the lower portion of the demising wall.
While the illustrated example of a building assembly in
As with the upper portion of the demising wall, the lower portion of a demising wall (e.g., demising wall 406-a) may be coupled to both the diaphragm beam (e.g., via brackets 412) and to the floor panel (e.g., via trim pieces 414). To couple the lower portion of a demising wall to the diaphragm beam, the demising wall may be positioned vertically over the diaphragm beam and mechanically secured thereto. The brackets 412 may be pre-installed to the diaphragm beam (e.g., in the factory or at the building side) prior to positioning the wall 406-a onto the diaphragm beam. In such examples, at least part of the lower portion of demising wall 406-a (e.g., the studs and the lower portion of the layers 305) may be seated in the track defined between brackets 412, and then mechanically secured thereto by fastening through the brackets, layers 305, and into the studs of the wall. In other embodiments, the wall 406-a may be aligned and positioned at the desired location onto the diaphragm beam and the brackets 412 may be mechanically coupled (e.g., fastened or welded) to both the wall 406-a and the beam 230-2. In yet other embodiments, the brackets 412 may be pre-installed on the wall (e.g., at the factory) before installing the wall to the diaphragm beam. In such examples, the brackets 412 may be used to align and set the wall in the desired location with respect to the beam 230-2. In some examples, the brackets 412 may be L-shaped, T-shaped, Z-shaped (e.g., with a portion extending vertically down along a vertical side of the diaphragm beam and a portion extending vertically up from the horizontal side of the beam), or otherwise suitably shaped for joining the wall 406-a to the beam 230-2.
As shown, the outer sides of the pair of wall boards or layers 305 may define a distance therebetween, which is narrower than the distance between the edges of the horizontally adjacent floor-ceiling panels. Thus, the demising wall may be configured such that the lower portion thereof can be received and may sit at an elevation below the upper or floor side of the floor-ceiling panels. The interior finish panels, on the other hand, may define a distance therebetween which is wider than the gap between the two floor-ceiling panels and thus, the finish panels may at least partially overlap the floor side of the floor-ceiling panels when installed, thereby enabling a joint between the wall and floor-ceiling panel that provides an aesthetically pleasing look.
Referring now also to
Additional walls (e.g., an end wall, a window wall, etc.) may be coupled vertically to the diaphragm to seal the envelope of the building. In some embodiments, the building assembly may include one or more additional pre-assembled walls, for example one or more utility walls 501-a, 501-b as shown in
Additionally, as shown in
The building assembly 600 may include a diaphragm beam 230-1, which in some embodiments may be filled with a mineral-based material 405, e.g., concrete, and/or other type of non-combustible or fire-resistant material. Similar to diaphragm beam 230-2, the diaphragm beam 230-1 may be implemented using an elongate, closed cross-section member 403, such as a steel, hollow structural section (HSS) beam, and which encloses the mineral-based material 405 or other type of non-combustible or fire-resistant material. Filling the interior of the diaphragm beams with a mineral-based or other type of non-combustible or fire-resistant material may enable the beam 230-1 to meet fire code, and thus obviate the need to use other types of fire resistant treatments (e.g., intumescent paint, spray on insulation, etc.). Also, the filling of the diaphragm beam with a mineral-based material may provide improved load-carrying capability which may enable the construction of a diaphragm that is not supported by beams along at least some edges (e.g., the longitudinal edges) of the diaphragm. In some embodiments, the diaphragm beam 230-1 may include an at least one reinforcing member 407 embedded in the mineral-based material 405. For example, the reinforcing member(s) may include one or more elongate metal rods (e.g., rebar) which extend along at least a portion of, and in some cases along the full length, of the diaphragm beam 230-1. The closed cross-section member 403 may include upper and lower horizontal sides 408-1, 408-2, respectively, and opposite vertical sides 409-1 and 409-2. In some embodiments, one or more of the beams of the external structural frame, e.g., frame beam 214-1a, may also be filled with a mineral-based material 405, such as concrete, and/or internally reinforced by reinforcing member(s) embedded in the mineral-based material, which may enhance the loadbearing capability of the structural frame and/or provide other advantages.
The building assembly 600 may be used to implement the joint between two vertically adjacent end walls (e.g., end walls 608-a and 608-b), a diaphragm beam (e.g., diaphragm beam 230-1, which in the context of this discussion may also be referred to as end diaphragm beam), and a floor-ceiling panel (e.g., floor-ceiling panel 222-a) terminating at the diaphragm beam. The floor-ceiling panel 222-a is arranged adjacent to one of the vertical sides, in this case vertical side 409-2 of the end diaphragm beam 230-1, and the end walls 608-a and 608-b are each positioned adjacent to the respective horizontal side 408-1 and 408-2 of the end diaphragm beam 230-1. As with the example in
The water-impermeable member 710 may be an elongate member coupled to the diaphragm beam 230-1 such that it covers the outer vertical side 409-1 of diaphragm beam 230-1. The water-impermeable member may thus be used to seal the envelope, e.g., by waterproofing the joint between upper and lower exterior or envelope walls and/or thermally insulating an otherwise thermally conductive metal beams. In some examples, the water-impermeable member 710 may be an elongate member fabricated as an extrusion or a pultrusion from a plastic or composite material (e.g., a fiber reinforced plastic (FRP)). In some embodiments, the elongate member may cover at least a portion of the upper and/or lower horizontal sides of the diaphragm beam. In some embodiments, the elongate member may include a vertically extending flange configured to be received between an exterior cladding layer and a stud of the pre-assembled wall. In some embodiments, the elongate member may be coupled to the diaphragm beam such that it defines a cavity between the elongate member. The cavity may provide thermal insulation. In some examples, the cavity may contain a thermally-insulative material such as semi-rigid mineral wool, a thermal blanket material or the like.
To assemble the floor-ceiling panel 222-a to the end diaphragm beam 230-1, the panel 222-a may be positioned adjacent to the interior vertical side 409-2 of beam 230-1 and may then be coupled to the beam 230-1, for example by welding or mechanically fastening the panel 222-a to the beam 230-1. As will be appreciated, this may occur concurrently with the arranging of the floor-ceiling panel 222-a to the intermediate diaphragm beam 230-2, such as by vertically dropping the panel 222-a in the space defined by the beams 230-1 and 230-2 and resting the panel 222-a onto the support brackets of the respective beams 230-1 and 230-2. Similar to beam 230-2, the end diaphragm beam 230-1 may include a support bracket an L-shaped or T-shaped bracket, or differently-shaped bracket) that extend continuously or discontinuously along some or substantially the full length of the beam 230-1, with one of the legs of the bracket extending outwardly from (e.g., perpendicularly to) the vertical side 409-2 of the beam to support the edge of the panel 222-a. The support brackets may be pre-installed (e.g., in the factory) on the beam or installed thereto at the building site. As described with respect to the opposite side of panel 222-a, the panel 222-a may include another connector bracket 271-a (e.g., a L-shaped, T-shaped bracket, or differently-shaped bracket, that has a portion extending outwardly from the panel's edge) for coupling the panel 222-a also to the end diaphragm beam 230-1. Once the panel 222-a is placed in position (e.g., rested onto support brackets of the beams), the connector brackets 271-a, and 270-a previously described, may be joined to the beam, such as by welding or mechanically fastening the brackets, for example to the upper horizontal side of the respective beam. When multiple floor-ceiling panels form the floor system for a given unit or room, the multiple floor-ceiling panels may each be individually jointed to the end diaphragm beam in a similar manner. In the illustrated example, the ceiling side of the floor-ceiling panel 222-a is above the lower horizontal side 408-2 of the diaphragm beam 230-1, and the floor side of the floor-ceiling panel 222-a is slightly above the upper horizontal side 408-1 of the diaphragm beam 230-1, however a different arrangement may be used in other embodiments, such as by configuring the components and coupling the floor-ceiling panel 222-a at a different vertical elevation relative to the diaphragm beams.
As shown in the illustrated example in
The end walls 608-a and 608-b may be non-loadbearing and may thus be coupled to the diaphragm in a manner so as not to transmit or carry any appreciable structural loads. As described, building or structural loads may be transferred directly from the diaphragm to the external structural frame, e.g., by load paths provided by the floor-ceiling panels and diaphragm beams (see for example, the diaphragm to frame joints in
For example, the non-rigid connection may be implemented using a bracket 401 which is attached to the lower horizontal side 408-2 of beam 230-1 and includes a slot in the vertically extending portion of the bracket 401. The diaphragm beam 230-1 may be pre-assembled to include the bracket 401 or the bracket 401 may be installed to the beam at the building side. When assembling an end wall, for example end wall 608-b, to the building, the lower portion of end wall 608-b may be positioned over the diaphragm beam 230-1 and secured thereto (e.g., via brackets 412, which extend vertically upward from the upper horizontal side 408-1 of diaphragm beam 230-1). The joining of at least some of the pre-assembled walls (e.g., the end walls and demising walls) would typically occur after the supporting diaphragm (e.g., diaphragm beams and floor-ceiling panels associated with the floor system of a given story) has been installed but prior to the upper diaphragm (e.g., diaphragm beams and floor-ceiling panels associated with the ceiling system of a given story) have been installed. After certain ones of the pre-assembled walls (e.g., end walls and demising walls) have been erected and joined to the floor system, the upper diaphragm may be installed, e.g., by installing diaphragm beams over the free ends of the walls and coupling floor panels to and between the diaphragm beams.
For example, an upper diaphragm beam (e.g., end beam 230-1) may be positioned over an end wall 608-b such that the bracket 401 and the vertically extending portion 701 of member 410 engage the upper portion of the end wall 608-b. The distance between the bracket 401 and portion 701 may be selected to accommodate at least part of the upper portion of the end wall 608-b (e.g., at least the upper ends of studs 606, and in some cases the upper ends of the studs and the wall panels 605) therebetween. The joints between the beam 230-1 and end walls 608-a, 608-2-b may be shimmed as needed. A vertically aligned slot may be provided in the vertically extending portion of bracket 401 such that the bracket can move relative to the upper portion of wall 608-b while remaining attached to one another (e.g., via one or more fasteners passing through the slot). The vertically extending portion 701 of member 410 may be adjacent to, and in some cases abut, the exterior side of the wall 608-b but may not be otherwise fixed to the exterior side of the wall 608-b to allow for relative movement between the beam 230-1 and wall 608-b. Additionally and optionally a non-rigid material, such as semi-rigid insulation or a compliant material, may be provided between the opposing surfaces of the demising wall 608-b and the diaphragm beam 230-1. The opposite side of the end wall, in this case the lower side of the end wall, may be rigidly joined to the supporting diaphragm beam (e.g., via a bracket such as an L-shaped, T-shaped, Z-shaped, or other suitably shaped bracket having at least a portion extending upward from the beam). In some embodiments, the location of the rigid and non-rigid connections may be reversed (e.g., the non-rigid connection may instead be provided at the lower end of the end wall).
In some embodiments, the building assembly 600 may include one or more additional pre-assembled walls, for example utility wall 501-a as shown in
A building assembly in accordance with further embodiments of the present disclosure may include a pair of diaphragm beams (e.g., diaphragm beams 230-1 and 230-2), each filled with a mineral-based material and each having opposite ends connected to an external structural frame of a building. The building assembly may further include at least one a pre-assembled floor-ceiling panel (e.g., panel 222-a) which is arranged between and coupled to the pair of diaphragm beams. The pre-assembled floor-ceiling panel (e.g., panel 222-a) may span the full distance between the diaphragm beams (e.g., have a longitudinal length which is substantially the same as the distance between the diaphragm beams), and in some embodiments, multiple such The pre-assembled floor-ceiling panel may be arranged along the transverse direction (e.g., along the length of the pair of diaphragm beams) to form a diaphragm (e.g., diaphragm section 220-1 in
In some embodiments, the building assembly may further include another pre-assembled wall connecting the first and second pre-assembled walls and which includes one or more plumbing conduits. For example,
As shown in
As described, the utility walls 501-a, 501-b may be pre-assembled to include some or all of the components (e.g., insulation 502, electrical conduits, plumbing conduits 509, etc.) as may be needed to support the use of the associated units/rooms. Some or all of these internal components may be substantially enclosed between wall panels or layers 506 that are attached to opposite sides of a wall-frame. The wall panels or layers may be formed of a variety of non-combustible or mineral-based materials, as described herein. As the utility walls 501-a, 501-b in this example are envelope wall, the exterior sides of the walls 501-a, 501-b include an exterior finish material 503 (e.g., one or more cladding layers) and the interior sides of the walls 501-a, 501-b include an interior finish material 505. The interior finish material 505 may be coupled to the interior sides of the walls 501-a, 501-b using one or more brackets 504, which may be configured to provide the interior finish material 505 in a spaced arrangement with respect to the wall panels 506. The cavity defined between the interior finish material 505 and the interior wall panels 506 may be sized to accommodate portions of the conduits that extend through the wall panels 506, such as to accommodate coupling of the conduits of vertically adjacent utility walls.
In some embodiments, the pair of diaphragm beams discussed previously (e.g., beams 230-2 and 230-1), which support a floor-ceiling panel such as panel 222-3, may be a first pair of diaphragm beams, To define another story of the building, a building assembly according to the examples herein may include at least one second pair of diaphragm beams coupled to the external structural frame at a vertical location above the first pair of diaphragm beams (and correspondingly above a first pair of pre-assembled walls that are supported by the first pair of diaphragm beams). In some embodiments, the pre-assembled utility wall may be tall enough to span more than a singly story, e.g., it may extend from below the first pair of diaphragm beams and corresponding floor-ceiling panels to above the second pair of diaphragm beams and corresponding floor-ceiling panels. For example, as shown in

It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.
It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations).
Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.
As will be understood by one skilled in the art, for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible subranges and combinations of subranges thereof. Any listed range can be easily recognized as sufficiently describing and enabling the same range being broken down into at least equal halves, thirds, quarters, fifths, tenths, etc. As a non-limiting example, each range discussed herein can be readily broken down into a lower third, middle third and upper third, etc. As will also be understood by one skilled in the art all language such as “up to,” “at least,” “greater than,” “less than,” and the like include the number recited and refer to ranges which can be subsequently broken down into subranges as discussed above. Finally, as will be understood by one skilled in the art, a range includes each individual member. Thus, for example, a group having 1-3 items refers to groups having 1, 2, or 3 items. Similarly, a group having 1-5 items refers to groups having 1, 2, 3, 4, or 5 items, and so forth.
While the foregoing detailed description has set forth various embodiments of the devices and/or processes via the use of block diagrams, flowcharts, and/or embodiments, such block diagrams, flowcharts, and/or embodiments contain one or more functions and/or operations, it will be understood by those within the art that each function and/or operation within such block diagrams, flowcharts, or embodiments can be implemented, individually and/or collectively, by a wide range of hardware, software, firmware, or virtually any combination thereof.
The herein described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected”, or “operably coupled”, to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable”, to each other to achieve the desired functionality. Specific embodiments of operably couplable include but are not limited to physically mateable and/or physically interacting components and/or wirelessly interactable and/or wirelessly interacting components and/or logically interacting and/or logically interactable components.
While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
The present application is a non-provisional application that claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Patent Application No. 62/505,703, filed on May 12, 2017, entitled “BUILDING SYSTEM WITH A DIAPHRAGM PROVIDED BY PRE-FABRICATED FLOOR PANELS,” which is incorporated herein by reference in its entirety.
