MODULAR BUILDING SYSTEM

Abstract

A manufactured building system is described. The building system can include modular components such as floor panels, roof panels, window walls, demising walls, utility walls, end walls, and/or corbel beams.

Description

BACKGROUND

Conventional construction is 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.

Traditional building construction continues to be more and more expensive and more and more complex. Changing codes, changing environments, and new technology have all made the construction of a building more complex than it was 10 or more years ago. In addition, trade labor availability is being reduced significantly. As more and more craftsmen retire, fewer and fewer younger workers may be choosing the construction industry as a career, leaving the construction industry largely lacking in skilled and able men and women to do the growing amount of construction work.

DETAILED DESCRIPTION

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. 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 contemplated herein.

This disclosure is drawn, inter alia, to methods, systems, products, devices, and/or apparatuses generally related to modular building systems and components including floor panels, demising walls, end walls, utility walls, and window walls. The embodiments address, among other things, the factors described above and other considerations that are pushing more and more of the construction processes to be completed off-site and to happen in more of a manufacturing environment than a construction site environment.

In some embodiments, a building may have units, residences, rooms, etc. that have pre-manufactured modular wall, ceiling and floor panels. In some embodiments, when the building is being constructed, the wall, ceiling and floor panels may be installed. The wall, ceiling and floor panels may provide a portion of an interior and/or exterior of the building. In some embodiments, the wall, ceiling and floor panels may be coupled to one or more structural frame members of the building. In some embodiments, the wall, ceiling and floor panels may be attached to structural frame members, such as the corbel beams described herein.

In some embodiments, the material composition of the wall, ceiling and floor panels and/or corbel beams may include steel. In some embodiments, the material composition may include aluminum. In still other embodiments, the wall, ceiling and floor panels may be made from a variety of building suitable materials ranging from metals and/or metal alloys, to wood and wood polymer composites (WPC), wood based products (lignin), other organic building materials (bamboo) to organic polymers (plastics), to hybrid materials, earthen materials such as ceramics, or any other suitable materials or combinations thereof. In some embodiments, cement, grout, 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 wall, ceiling and floor panels and other building materials for other elements of the wall, ceiling and floor panels. 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 components in the wall, ceiling and floor panels described herein. Availability of various building materials in different parts of the world may also affect selection of materials for building the system 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 wall, ceiling and floor panels, corbel beam, and/or components thereof 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” or “grout” 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.

Some implementations can permit users to construct an apartment or hotel with a kit of manufactured components (e.g., wall, ceiling and floor panels) that can help reduce labor costs, reduce time for completion, and reduce first cost. Some implementations of a modular building system can include a kit of components that are sufficiently flexible to meet many different requirements, e.g., the same system can be used to make bedroom walls, living room walls, kitchen walls, and bathroom walls.

Some implementations of the manufactured systems described herein can meet the above requirements, among other things. In some implementations, a foundation of the finishes can include a cold formed steel hat channel that can be attached to any standard wall (e.g., a demising wall). The face of the hat channel can carry a simple aluminum extrusion or fiberglass reinforced pultrusion. A pultrusion is a member having a constant cross section and formed by a continuous process for manufacture of composite materials with constant cross-section, where the process involves the pulling of material. The extrusion or pultrusion can permit a very wide range of finishes to be attached to the wall and removed from the wall, and can provide a finish system that can be repaired with few or no tools. In some implementations, a closure extrusion simply captures the panel edge and snaps into the hat channel extrusion. In some implementations, panels can be various sizes and thicknesses. In some implementations, the wall system can include shelf brackets. In some implementations, the same extrusion and pultrusion slightly modified can be used in the bathroom for shower walls, bathroom walls, etc.

Some implementations can include a flexible design that accommodates many different finish material types. For example, wood, metal, and quartzite all can be accommodated. Some implementations can include low cost standardized components.

Using an implementation, apartment or hotel room walls can be constructed with a few different configurations resulting in large scale, low cost manufacturing techniques. In some implementations, wet or dry systems allow shower walls and living room walls to be accommodated with the same standardized components.

Some implementations can include an accessible design that permits electrical devices, plumbing pipes, and HVAC duct work to be easily accessed behind the finished panel system. In some implementations, the snap closure angles can include drilled holes (e.g., at 12 inches on center) to permit hanging televisions, paintings, etc. Some implementations can include a vertical shelf extrusion that permits placement of shelving, cabinets, and countertops.

As designers and builders search for lower cost ways to meet the built environment needs of people, one of the potential solutions is an integrated solution. An integrated solution can include two (or more) components that are traditionally separate products and installations to be integrated into one product solution. Some implementations of the manufactured wall, ceiling and floor panels described herein include an integrated solution that provides a modular building system.

FIG. 1 is a cross sectional view of an example floor panel 100 in accordance with some implementations. The floor panel 100 is constructed to form the floor of an upper unit and a ceiling of a lower unit (e.g., the floor of an apartment unit on a given floor and the ceiling of an apartment unit on a floor immediately below the given floor). The floor panel 100 includes a plurality of layers. In the description of layers and other components herein, reference is made to field panel installed, field finish installed and factory installed. In some implementations, field panel installed can refer to panels that are installed in the field by a panel erection crew (e.g., at a building site to install panels in a building) during a construction process. In some implementations, field finish installed can refer to layers or components that are installed in the field by a finish crew (e.g., at a building site on panels that have been installed in a building) during a construction process. In some implementations, factory installed can refer to layers or components that are installed in a factory setting during a manufacturing process, where the factory setting is different from the field or building site setting.

The floor panel 100 layers include, from top to bottom relative to the floors of a building, a finished flooring layer 102 (e.g., a ⅜″ finished floor that is field finish installed), an acoustical mat layer 104 (e.g., a ⅜″ acoustical mat that is field finish installed), a first cement board layer 106 (e.g., a ½″ cement board layer that is factory installed), a hydronic foam layer 112 (e.g., a 1″ hydronic foam layer that is factory installed) with hydronic piping 110 within the hydronic foam layer 112, a second cement board layer 114 (e.g., a ½″ cement board layer that is factory installed), and a first sheet metal layer 116 (e.g., a 22 ga galvanized steel sheet metal layer that is factory installed).

At the factory, the first cement board layer 106 is secured to the first sheet metal layer 116 using first fasteners 108 (e.g., #8×2.375″ self drilling screws at 12″ on center max). Also at the factory, the second cement board layer 114 is attached to the first sheet metal layer 116 via second fasteners 118 (e.g., #8×1¼″ self drilling screws).

Now, proceeding from the bottom of the floor panel 100 upwards, the layers include an aluminum light rail 136 (that is factory installed) extending below a ceiling panel layer 134 (e.g., a 1″ acoustical ceiling panel tile that is field finish installed) that is held in place by a track 128 (e.g., a pultrusion track that is factory installed) that is attached via a track clip 130 (e.g., an aluminum track clip that is field finish installed). Above the track clip 130 are one or more gypsum board layers 126 (e.g., two ⅝″ type ‘X’ fiberglass mat gypsum sheathing boards that are factory installed with staggered joints). The track clip 130 is attached to the one or more gypsum board layers 126 via third fasteners 132 (e.g., #6×1.1875″ self drilling screws).

Above the one or more gypsum board layers 126 is a second sheet metal layer 124 (e.g., a 22 ga galvanized steel sheet metal layer that is factory installed). The third fasteners 132 also extend through the second sheet metal layer 124.

The first sheet metal layer 116 and the second sheet metal layer 124 are joined by at least one metal joist 120 (e.g., a 10″ 14 ga metal joist with a 2½″ flange that is factory installed). Also, disposed in the space between the first sheet metal layer 116 and the second sheet metal layer 124 is one or more insulation layers 122 (e.g., two layers of 3½″ semi-rigid mineral wool batt insulation that are factory installed).

Thus for the floor panel 100, in some implementations, the layers or components that are field finish installed include the finished floor 102, acoustical mat 104, track clip 130, and ceiling panels 134. The remaining layers and components of the floor panel 100 may be factory installed to minimize labor in the field.

FIG. 2 is a cross sectional view of an example roof panel 200 in accordance with some implementations. The roof panel 200 would form the topmost horizontal panel in a building and comprise the ceiling panel of a top floor unit from the interior and the roof from the exterior of the top of the building. The roof panel 200 includes a plurality of layers.

Beginning from the top, exterior inward, the layers making up the roof include a roofing layer 202 (e.g., a single ply roofing membrane layer), a protection board layer 204 (e.g., a ½″ protection board layer), and a roof insulation layer 206 (e.g., a rigid insulation layer). In some implementations, the roof insulation and roof membrane can be field installed.

Continuing inward from the roof, the layers include a vapor retarder layer 208, a cement board layer 210 (e.g., a ½″ cement board that is factory installed), and a first sheet metal layer 212 (e.g., a 22 ga galvanized steel sheet metal layer). First fasteners 214 are used to attach the vapor retarder layer 208 and the cement board layer 210 to the first sheet metal layer 212.

Proceeding from the bottom of the roof panel 200 upwards, the layers include an aluminum light rail 232 (that is factory installed) extending below a ceiling panel layer 230 (e.g., a 1″ acoustical ceiling panel tile that is field finish installed) that is held in place by a track 224 (e.g., a pultrusion track that is factory installed) that is attached via a track clip 226 (e.g., an aluminum track clip that is field finish installed). Above the track clip 226 are one or more gypsum board layers 222 (e.g., two ⅝″ type ‘X’ fiberglass mat gypsum sheathing boards that are factory installed with staggered joints). The track clip 226 is attached to the one or more gypsum board layers 222 via second fasteners 228 (e.g., #6×1.1875″ self drilling screws).

Above the one or more gypsum board layers 222 is a second sheet metal layer 220 (e.g., a 22 ga galvanized steel sheet metal layer that is factory installed). The second fasteners 228 also extend through the second sheet metal layer 220.

The first sheet metal layer 212 and the second sheet metal layer 220 are joined by at least one metal joist 216 (e.g., a 10″ 14 ga metal joist with a 2½″ flange that is factory installed). Also, disposed in the space between the first sheet metal layer 212 and the second sheet metal layer 220 are one or more insulation layers 218 (e.g., two layers of 3½″ semi-rigid mineral wool batt insulation that are factory installed).

FIG. 3 is a cross sectional view of an example demising wall 300 in accordance with some implementations. A demising wall can include a wall forming a boundary that separates one tenant's space from that of another tenant and from a common corridor. A demising wall is also called a demising partition or party wall.

The demising wall 300 includes a plurality of layers and components. From exterior to interior on a first side, the layers include one or more interior finish panels 302 (e.g., a manufactured prefinished interior panel that is about 1′4″ high and is field finish installed). The interior finish panels 302 are held in place via a trim piece 304 (e.g., a fiberglass reinforced plastic pultrusion trim that is field finish installed) that includes an exterior portion and an interior portion. The interior portion of the of the trim piece 304 is attached to a hat channel 306 (e.g., a 2½″ deep by 2″ wide 20 ga hat channel with 1″ legs at 16″ on center). The hat channel 306 is screwed into a gypsum board layer 310 (e.g., a ⅝″ type ‘X’ fiberglass mat gypsum sheathing board) and on into a sheet steel 312 layer (e.g., 22 ga galvanized sheet steel) using fasteners 318. Within a space provided by the standoff of the hat channel 306 from the gypsum board layer 310, a duct 308 (e.g., a ⅛″ fiberglass reinforced plastic pultrusion duct) can be placed. In some implementations, the duct can be exhaust for kitchen, bathroom, dryer or incoming fresh air.

On a second side of the demising wall 300 opposite the first side, a mirror image set of the layers and components described above is provided. In the space between the first and second sides of the demising wall 300 are metal studs 314 (e.g., 3⅝″ 25 ga metal studs at 24″ on center). The fasteners 318 can extend through the sheet metal layer (e.g., 312) and into the metal stud 314. Also disposed in the space between the first and second sides of the demising wall 300 is an insulation layer 320 (e.g., 3½″ semi-rigid mineral wool batt insulation that is factory installed).

FIG. 4 is a cross sectional view of an example demising wall 400 at a doorway in accordance with some implementations. The demising wall 400 shown in FIG. 4 includes a bedroom wall at a doorway to a bedroom. The section view is of a horizontal section of the demising wall adjacent the doorway.

The demising wall 400 also includes two gypsum board layers 406 one disposed on each side of the demising wall 400. The gypsum board layers 406 can include a 5/8″ type ‘X’ fiberglass matt gypsum sheathing board.

The demising wall 400 also includes interior finish panels 408 disposed on each side of the demising wall 400. The interior finish panels 408 can be field installed and can be held in place by one or more trim pieces 410 (e.g., fiberglass reinforced plastic pultrusion trim).

The demising wall 440 also includes a hat channel 414 to which the trim pieces 410 are attached to via first fasteners 412 (e.g., #8½″ screws at 48″ on center). The hat channel 414 is attached to the gypsum board layer 406 via second fasteners 416 (e.g., #8 1⅝″ screws at 24″ on center). The demising wall 400 includes a door opening 418.

The demising wall 400 includes an end cap member 420 and trim pieces 422 (e.g., angled metal trim) that cover the gap created by the hat channels 414 between the gypsum board layers 406 and the finish panels 408. A door jamb 426 is coupled to the demising wall via a fastener 424. A door 428 is installed in the door opening 418.

The end wall 500 can include a plurality of layers and components. The layers and components can include—generally from the exterior to the interior—a factory installed exterior panel 502 (e.g., a 4 mm aluminum composite material panel that is factory installed), a furring member 504 (e.g., a 1″ extruded aluminum furring that is factory installed), a weather resistive barrier layer 506 (factory installed), first and second gypsum board layers 508 (e.g., ⅝″ ‘X’ type fiberglass matt sheathing board), a first thermal insulation layer 510 (e.g., ½″ thermal insulating material adhered to stud and factory installed), first and second sheet metal layers 512 (e.g., 22 ga galvanized sheet steel screwed into studs at 12″ on center and factory installed), metal studs 514 (e.g., 3⅝″ 18 ga metal stud at 24″ on center), and a second insulation layer 518 (e.g., 3½″ semi rigid mineral wool batt insulation, factory installed).

A drip flashing 520 (e.g., a pre-finished aluminum drip flashing) can be factory installed at the joints between the exterior finish panels 502. A vapor retarder layer 532 can be factory installed between the second insulation layer 518 and the second gypsum board layer 508 (e.g., the interior gypsum board layer).

Continuing on from exterior to interior, a plurality of hat channels 522 are factory installed on the second gypsum board layer 508 using second fasteners 524.

In some implementations, the walls described herein (e.g., utility, demising, etc.) can include vertical studs within an interior thermal envelope, where the vertical studs and thermal envelope are encased with an acoustic/fire barrier. Hat channel members are attached to the outer surfaces of the thermal envelop and provide space for horizontal distribution of pipes and modular electrical components. Within the two story wall panels (e.g., utility wall panels) vertical pipes run in vertical chase section to connect between floors. By providing vertical utility runs (e.g., pipes, etc.) within the two story wall panels, the number of connection compared to single story connection is reduced by half

Also, by encasing the vertical studs and thermal envelope within the acoustic/fire barrier and moving the utilities to the space between the acoustic/fire barrier and the finish system, a need to put holes into the acoustic/fire barrier is reduced or eliminated, which can improve acoustic performance characteristics. Also, because the finish system may include a finish system that is removable without tools, inspection and repair of any utilities running in the wall in the space provided by the hat channels is made significantly easier compared to conventional construction systems.

The examples provided herein are for explanatory purposes only and should not be considered to limit the scope of the disclosure. Each example embodiment may be practical for a particular environment such as urban mixed-use developments, low-rise residential units, and/or remote communities. Materials and dimensions for individual elements may be configured to comply with one or more of the following building codes: fire, energy, handicap, life-safety, and acoustical (impact and ambient noise transfer) without departing from the scope of the principles of the disclosure. The elements and/or system may also be configured to comply with social and/or religious codes as desired. For example, materials, systems, methods, and/or apparatuses may be configured to comply with the International Building Code as it has been adopted in a jurisdiction. Furthermore, various components have been referenced above as being field panel installed, field finish installed, and factory installed for some embodiments. Other embodiments may be provided in which the installation location and/or installation method may be different than those specifically referenced above. Still further, the various dimensions, gauges, and other specifications for various components described above are for example purposes—other embodiments may be implemented with components having different dimensions, gauges, specifications, etc.

The present disclosure is not to be limited in terms of the particular embodiments described in this application, which are intended as illustrations of various aspects. Many modifications and embodiments can be made without departing from its spirit and scope. Functionally equivalent methods and apparatuses within the scope of the disclosure, in addition to those enumerated herein, are possible from the foregoing descriptions. Such modifications and embodiments are intended to fall within the scope of the appended claims. The present disclosure is to be limited only by the terms of the appended claims, along with the full scope of equivalents to which such claims are entitled. This disclosure is not limited to particular methods, which can, of course, vary. 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, the terms can be translated 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.

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.).

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, 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.). 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, the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.

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. 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, 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.

The herein described subject matter sometimes illustrates different components contained within, or connected with, different other components. Such depicted architectures are merely embodiments, and 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.

While various aspects and embodiments have been disclosed herein, other aspects and embodiments are possible. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting.
