Definitions
- This invention relates to building panels and in particular cementitious prefabricated building panels such as cementitious Structural Insulated Panels (SIPs).
- SIPs cementitious Structural Insulated Panels
- Example embodiments provide prefabricated panels for achieving desired performance characteristics and methods for constructing buildings with the prefabricated panels.
- Constructing a building is typically an extensive project involving significant amounts of time and/or resources (labour, energy, materials, etc.). Moreover, the carbon footprint of a building built using existing systems and methods can be large.
- Reducing the amount of time and/or resources required to construct a building can be desirable. Reducing the carbon footprint of a building can also be desirable. With more environmentally stringent building codes being passed regularly, reducing the amount of resources used to construct a building and the carbon footprint of the building is increasingly becoming a requirement to be in compliance with new building codes.
- This invention has a number of aspects. These include, without limitation:
- FIG. 1 A is a perspective view of a panel according to an example embodiment of the invention described herein.
- FIG. 1 B is a cross-sectional view of the panel of FIG. 1 A .
- FIG. 1 J is a partial cross-sectional view of a panel according to an example embodiment of the invention described herein.
- FIG. 3 is a block diagram illustrating a method for constructing a building according to an example embodiment of the invention.
- FIG. 4 B is a side view and FIG. 4 C is a perspective view of a connector according to an example embodiment of the invention described herein.
- FIG. 4 D is a perspective view and FIG. 4 E is a back view of a structural post according to an example embodiment of the invention described herein.
- FIGS. 4 F to 4 I are perspective views of example couplings of a panel to a structural post according to example embodiments of the invention described herein.
- FIG. 4 J is a schematic illustration showing example movement of a structural post relative to a panel which is coupled to the post during a seismic event (or other exertion of force).
- FIGS. 4 K to 4 M are perspective views of example couplings of panels to an underlying structure of a building according to example embodiments of the invention described herein.
- FIG. 5 B is a front view of the panel of FIG. 5 A .
- FIG. 5 E is an exploded perspective view of the panel of FIG. 5 A .
- FIG. 6 A is a perspective view of a roof panel according to an example embodiment of the invention described herein.
- FIG. 6 C is a perspective view of Q-deck sheeting of a prefabricated panel according to an example embodiment of the invention described herein.
- One aspect of the technology described herein provides an exterior cladding panel.
- a plurality of panels may be used to quickly and efficiently assemble exterior walls of a building under construction.
- the cladding panel is coupled to an underlying structure that has been assembled on site (e.g. a steel I-beam structure).
- the cladding panel is coupled to other pre-fabricated panels which form part of the structure of the building under construction.
- the cladding panel described herein may be coupled flush against structural posts, beams and/or the like.
- the exterior cladding panel is preferably plant finished (e.g. fully manufactured at a factory).
- a plurality of the exterior cladding panels may also preferably be easily and quickly shipped to a construction site (e.g. on a flatbed truck, within shipping containers, on railway cars, etc.). Once the panels arrive at the construction site they may be easily and quickly assembled together.
- FIG. 1 A is a perspective view and FIG. 1 B is a cross-sectional view of an example cladding panel 10 .
- Example panel 10 comprises an insulative core 12 having opposing faces 12 A and 12 B.
- Insulative core 12 provides a thermal break between face 10 A and face 10 B of panel 10 .
- Insulative core 12 may also at least partially structurally support panel 10 .
- Insulative core 12 may also at least partially dampen sound transmission through panel 10 .
- Insulative core 12 preferably comprises a single piece of insulation. However, this is not necessary. In some embodiments insulative core 12 is made of two or more pieces of insulation.
- insulative core 12 comprises rigid foam insulation.
- insulative core 12 comprises expanded polystyrene (EPS), polyisocyanurate (polyiso), extruded polystyrene (XPS) and/or the like.
- insulative core 12 at least partially comprises mineral fiber rigid insulation.
- insulative core 12 is at least about 3 inches thick (e.g. for warmer climates, etc.). In some embodiments insulative core 12 is at least about 24 inches thick (e.g. to comply with passive housing standards, for cold climates, etc.). In some embodiments insulative core 12 is between 3 and 24 inches thick.
- Insulative core 12 typically has an insulative R-value of about R4 per inch. In some embodiments insulative core 12 has an insulative R-value of at least R12. In some embodiments insulative core 12 has an insulative R-value of at least R96. In some embodiments insulative core 12 has an insulative R-value between R12 and R96.
- one or both of surfaces 12 A and 12 B are covered by two or more different cementitious layers.
- the different cementitious layers may have different properties.
- one or both of surfaces 12 A and 12 B may each be covered with two or more different cementitious layers.
- a first one of the cementitious layers may be more fire resistant (e.g. comprises a more fire resistant cementitious material thereby increasing fire resistance of panel 10 ) while a second one of the cementitious layers may be structurally stronger (e.g. comprises a higher strength cementitious material thereby increasing structural strength of panel 10 ).
- a cementitious material which covers at least one of surfaces 12 A or 12 B of insulative core 12 comprises a lower density (e.g. 5-35 megapascals (MPa)) cementitious material.
- the lower density cementitious material may provide high fire protection characteristics (e.g. at least 2 hours at 1800 degrees Fahrenheit, is compliant with fire resistant standards (e.g. CAN/ULC-S101 Fire-Resistance Ratings, etc.) and/or the like). Additionally, or alternatively the lower density cementitious material may provide high amounts of sound dampening (e.g. at least 50 STC (sound transmission class)).
- a cementitious material which covers at least one of surfaces 12 A or 12 B of insulative core 12 comprises a higher density (e.g. 35-90 p MPa) cementitious material.
- the higher density cementitious material may provide increased amounts of structural strength (e.g. a compressive strength in the range of about 120 to 160 Pound-force per Cubic Foot (PCF)).
- the higher density cementitious material has a density in the range of about 90 to 200 MPa and provides even higher amounts of structural strength.
- At least one of surfaces 12 A and 12 B of insulative core 12 is covered by both a lower density cementitious layer and a higher density cementitious layer.
- a cementitious material which covers at least one of surfaces 12 A or 12 B (or any other portion) of insulative core 12 is curable.
- the cementitious material may be poured or cast over at least one of surfaces 12 A or 12 B (or any other portion) of insulative core 12 and cured. As the cementitious material cures, the cementitious material may bond directly to insulative core 12 (e.g. forming a “wet bond”).
- one or more side or peripheral edges 16 of panel 10 may comprise one or more embedded elements 14 .
- Side or peripheral edges 16 may, for example, extend between surfaces 10 A and 10 B of panel 10 .
- embedded elements 14 extend along all peripheral edges 16 of panel 10 (e.g. embedded elements 14 enclose the peripheral edges of core 12 ). In some embodiments embedded elements 14 extend only along some edges 16 of panel 10 .
- the one or more embedded elements 14 may structurally couple opposing faces 10 A and 10 B together with insulative core 12 thereby increasing overall strength of panel 10 . Additionally, or alternatively, the one or more embedded elements 14 may provide a thermal break between opposing faces 10 A and 10 B. Additionally, or alternatively, the one or more embedded elements 14 may enclose insulative core 12 preventing leakage of insulative core 12 thereby improving fire resistance of panel 10 (e.g. insulative core 12 may be flammable in liquid form).
- connectors for coupling panel 10 to structural elements of a building, to adjacent panels, and/or the like are coupled directly to one or more of the embedded elements 14 .
- panel 10 comprises a connector in each corner of panel 10 .
- panel 10 comprises a connector in at least two corners of panel 10 .
- one or more of the connectors are hidden (e.g. a person cannot readily see the connector when the panel is finished or installed).
- one or more of the connectors are flush with one or more surfaces of a panel (e.g. panel 10 ).
- one or more hoisting points for lifting panel 10 may be directly coupled to at least one embedded element 14 .
- one or more hoisting points are coupled to at least one embedded element 14 A.
- one or more hoisting points are coupled to at least one embedded element 14 B.
- one or more hoisting points are coupled to at least one embedded element 14 A and at least one embedded element 14 B.
- the one or more embedded elements 14 may comprise (non-limiting):
- An embedded element 14 may span an entire edge of panel 10 . However this is not mandatory. In some embodiments an embedded element 14 only partially extends along an edge of panel 10 . In some embodiments panel 10 comprises no embedded elements 14 .
- an embedded element 14 has a low thermal conductivity (e.g. maintains thermal break between faces 10 A and 10 B of panel 10 ).
- the example panel 10 shown in FIG. 1 B comprises embedded elements 14 comprising an extruded fibreglass channel 14 A and a steel channel 14 B.
- panel 10 comprises both a fibreglass channel and a steel channel
- connectors for connecting panel 10 to other elements of a building under construction may be coupled directly to steel channel 14 B.
- both fibreglass channel 14 A and steel channel 14 B extend along all peripheral edges of panel 10 .
- FIG. 1 C is a side view of example panel 10 .
- one or more pins, fasteners, rods, etc. extend through an embedded element 14 into cementitious material that is bonded (directly or indirectly) to insulative core 12 .
- the one or more pins, fasteners, rods, etc. may, for example, increase the strength of the coupling between the embedded element 14 through which the pin, fastener, rod, etc. extends through, the cementitious material and/or insulative core 12 .

Description
- This application claims the benefit under 35 U.S.C. § 119 of U.S. application No. 63/212604 filed 18 Jun. 2021 and entitled PREFABRICATED INSULATED BUILDING PANELS AND METHODS OF CONSTRUCTING BUILDINGS which is hereby incorporated herein by reference for all purposes.
- This invention relates to building panels and in particular cementitious prefabricated building panels such as cementitious Structural Insulated Panels (SIPs). Example embodiments provide prefabricated panels for achieving desired performance characteristics and methods for constructing buildings with the prefabricated panels.
- Constructing a building is typically an extensive project involving significant amounts of time and/or resources (labour, energy, materials, etc.). Moreover, the carbon footprint of a building built using existing systems and methods can be large.
- Reducing the amount of time and/or resources required to construct a building can be desirable. Reducing the carbon footprint of a building can also be desirable. With more environmentally stringent building codes being passed regularly, reducing the amount of resources used to construct a building and the carbon footprint of the building is increasingly becoming a requirement to be in compliance with new building codes.
- One way the amount of time and/or resources required can be reduced is by constructing the building using prefabricated panels. Existing prefabricated panels however are heavy, cannot provide the required performance characteristics, etc. Additionally, existing prefabricated panels may be difficult to maneuver into place and to couple together.
- There remains a need for practical and cost effective ways to construct prefabricated building panels using systems and methods that improve on existing technologies.
- This invention has a number of aspects. These include, without limitation:
-
- non-load bearing prefabricated panels;
- load bearing prefabricated panels;
- prefabricated roofing panels;
- methods for constructing a single story building;
- methods for installing a roof of a building; and
- methods for coupling prefabricated panels to a structure of a building, such as a foundation and a metal framework installed on the foundation.
- Further aspects and example embodiments are illustrated in the accompanying drawings and/or described in the following description.
- It is emphasized that the invention relates to all combinations of the above features, even if these are recited in different claims.
- The accompanying drawings illustrate non-limiting example embodiments of the invention.

- One aspect of the technology described herein provides an exterior cladding panel. A plurality of panels may be used to quickly and efficiently assemble exterior walls of a building under construction. In some cases the cladding panel is coupled to an underlying structure that has been assembled on site (e.g. a steel I-beam structure).

For example,surface 12A may be covered by acementitious layer 13A andsurface 12B may be covered by acementitious layer 13B (see e.g.FIG. 1 B). In embodiments where both ofsurfaces surfaces surface 12B). - In some embodiments one or both of
surfaces surfaces - In some embodiments a cementitious material which covers at least one of
surfaces insulative core 12 comprises a lower density (e.g. 5-35 megapascals (MPa)) cementitious material. The lower density cementitious material may provide high fire protection characteristics (e.g. at least 2 hours at 1800 degrees Fahrenheit, is compliant with fire resistant standards (e.g. CAN/ULC-S101 Fire-Resistance Ratings, etc.) and/or the like). Additionally, or alternatively the lower density cementitious material may provide high amounts of sound dampening (e.g. at least 50 STC (sound transmission class)). - In some embodiments a cementitious material which covers at least one of
surfaces insulative core 12 comprises a higher density (e.g. 35-90 p MPa) cementitious material. The higher density cementitious material may provide increased amounts of structural strength (e.g. a compressive strength in the range of about 120 to 160 Pound-force per Cubic Foot (PCF)). In some embodiments the higher density cementitious material has a density in the range of about 90 to 200 MPa and provides even higher amounts of structural strength. - As described above, in some embodiments at least one of
surfaces insulative core 12 is covered by both a lower density cementitious layer and a higher density cementitious layer. - In some embodiments a cementitious material which covers at least one of
surfaces insulative core 12 is curable. For example, the cementitious material may be poured or cast over at least one ofsurfaces insulative core 12 and cured. As the cementitious material cures, the cementitious material may bond directly to insulative core 12 (e.g. forming a “wet bond”). - As shown in
FIG. 1 B, which is an example cross-sectional view ofpanel 10, one or more side orperipheral edges 16 ofpanel 10 may comprise one or more embeddedelements 14. Side orperipheral edges 16 may, for example, extend betweensurfaces panel 10. In some embodiments embeddedelements 14 extend along allperipheral edges 16 of panel 10 (e.g. embeddedelements 14 enclose the peripheral edges of core 12). In some embodiments embeddedelements 14 extend only along someedges 16 ofpanel 10. - The one or more embedded
elements 14 may structurally couple opposingfaces insulative core 12 thereby increasing overall strength ofpanel 10. Additionally, or alternatively, the one or more embeddedelements 14 may provide a thermal break between opposingfaces elements 14 may encloseinsulative core 12 preventing leakage ofinsulative core 12 thereby improving fire resistance of panel 10 (e.g. insulativecore 12 may be flammable in liquid form). - In some embodiments connectors for
coupling panel 10 to structural elements of a building, to adjacent panels, and/or the like are coupled directly to one or more of the embeddedelements 14. In someembodiments panel 10 comprises a connector in each corner ofpanel 10. In someembodiments panel 10 comprises a connector in at least two corners ofpanel 10. In some embodiments one or more of the connectors are hidden (e.g. a person cannot readily see the connector when the panel is finished or installed). In some embodiments one or more of the connectors are flush with one or more surfaces of a panel (e.g. panel 10). - Additionally, or alternatively, one or more hoisting points for lifting panel 10 (e.g. with a crane) may be directly coupled to at least one embedded
element 14. In some embodiments one or more hoisting points are coupled to at least one embeddedelement 14A. In some embodiments one or more hoisting points are coupled to at least one embeddedelement 14B. In some embodiments one or more hoisting points are coupled to at least one embeddedelement 14A and at least one embeddedelement 14B. - The one or more embedded
elements 14 may comprise (non-limiting): -
- an extruded fibreglass channel (e.g. a C-shaped channel);
- a custom fibreglass extrusion (e.g. shaped to incorporate additional elements such as a dry seal gasket);
- a steel or other metal channel (e.g. a C-shaped channel);
- a structural steel or other metal (e.g. HSS, etc.) element;
- a custom steel or other metal element;
- custom aluminum, vinyl, PVC, steel, fibreglass, carbon fiber, basalt or the like extrusions (preferably low or no thermal conductivity);
- combinations of any two or more of the above;
- etc.
- An embedded
element 14 may span an entire edge ofpanel 10. However this is not mandatory. In some embodiments an embeddedelement 14 only partially extends along an edge ofpanel 10. In someembodiments panel 10 comprises no embeddedelements 14. - Preferably an embedded
element 14 has a low thermal conductivity (e.g. maintains thermal break betweenfaces - The
example panel 10 shown inFIG. 1B comprises embeddedelements 14 comprising an extrudedfibreglass channel 14A and asteel channel 14B. In such embodiments wherepanel 10 comprises both a fibreglass channel and a steel channel, connectors for connectingpanel 10 to other elements of a building under construction may be coupled directly tosteel channel 14B. In some embodiments bothfibreglass channel 14A andsteel channel 14B extend along all peripheral edges ofpanel 10. - As described above, one or more of embedded
elements 14 may comprise a C-shaped channel structure or the like. In some embodiments the open end of the C-shaped channel structure may face inwards towardsinsulative core 12. In some embodiments the open end of the C-shaped channel structure may face outwards away from insulativecore 12. For example, the open ends of embeddedelements 14 which extend along the top and/or bottom edges ofpanel 10 may face inwards to create flat edges. The open ends of at least some of embeddedelements 14 may, for example, face outwards along side edges of panel 10 (for better coupling against a column or post, to accommodate bolts which are present in a column or post, etc.). In some embodiments the open end which faces outwards away from insulativecore 12 is filled with an insulative foam or the like. In some embodiments two adjacent embedded elements may have open ends which face in opposite directions (see e.g.FIG. 1B ). -
FIG. 1C is a side view ofexample panel 10. -
FIGS. 1 D-11 are schematic cross-sections ofpanel 10 illustrating different example configurations of embeddedelements 14.FIGS. 1D-1F and 11 illustrate example embodiments wherepanel 10 comprises bothfibreglass channel 14A andsteel channel 14B.FIG. 1G illustrates an example embodiment wherepanel 10 comprises just afibreglass channel 14A. In such embodiments the fibreglass channel(s) 14A may provide a structural frame forsuch panel 10.FIG. 1H illustrates an example embodiment wherepanel 10 comprises acustom fibreglass channel 14A configured to receive a sealinggasket 14C (e.g. a rubber gasket that provides a seal between two adjacent panels when they are coupled together). - In some embodiments a pin, mechanical fastener or the like may couple two adjacent embedded
elements 14 together (see e.g.FIG. 1J whereexample pin 14D couplesfibreglass channel 14A withsteel channel 14B). - In some embodiments one or more pins, fasteners, rods, etc. extend through an embedded
element 14 into cementitious material that is bonded (directly or indirectly) toinsulative core 12. The one or more pins, fasteners, rods, etc. may, for example, increase the strength of the coupling between the embeddedelement 14 through which the pin, fastener, rod, etc. extends through, the cementitious material and/orinsulative core 12. - One or more
embedded elements 14 may also extend along edges of an aperture within panel 10 (e.g. a window or door opening). For example, both afibreglass channel 14A and asteel channel 14B may extend around a window or door opening. Preferably window or door frames being coupled tosuch panel 10 are secured tosteel channel 14B due to the steel channel's increased ability to withstand shear forces (e.g. wind shear, etc.). Ifsteel channel 14B is embedded deeper than the window or door frame, the window or door frame may, for example, be coupled tosteel channel 14B using an “L” shaped angle connector. In some embodiments a window or door frame may be secured tofibreglass elements 14A (or another embedded element 14). In somesuch embodiments elements 14A may transfer load (e.g. wind shear, etc.) to a structural framework ofpanel 10. In someembodiments elements 14A transfer load toelements 14B which may be adjacent or proximate to theelements 14A. -
Panel 10 comprises reinforcing elements 15 (e.g. a mesh such as a welded wire mesh, epoxy coated wire mesh, glass mesh and/or the like) which are embedded into the cementitiousmaterial covering surface 12A and/or 12B ofinsulative core 12. Reinforcingelements 15 may extend from the cementitious material, pass under an embedded element (or elements) 14 and into cementitious material on an opposing side of the embedded element (or elements). Reinforcingelements 15 may, for example, comprise an “S-like” shape (see e.g.FIGS. 1B-1G ). In some embodiments a cementitious material encloses reinforcingelements 15. In some embodiments pins, fasteners, rods, etc. which extend through an embeddedelement 14 increase the strength of the coupling between reinforcingelement 15 and the embeddedelement 14. - In some
embodiments reinforcing element 15 and embedded element(s) 14 are together fused to insulative core 12 (each ofelements 15 andelements 14 may be individually or together fused to insulative core 12). For example, reinforcingelement 15 and embedded element(s) 14 may be fused together to insulativecore 12 with an adhesive or other bonding agent and/or cementitious material. In someembodiments reinforcing element 15 and embedded element(s) 14 are fused toinsulative core 12 with the cementitious material that covers a surface ofinsulative core 12. In someembodiments reinforcing element 15 and embedded element(s) 14 are fused together to insulativecore 12 with an epoxy resin. In some embodiments a reinforcingelement 15 is coupled to a surface (or surfaces) of an embedded element 14 (e.g. with a bonding agent (e.g. epoxy), a mechanical coupling method (e.g. fastening, weaving or sewing mesh onto surface (or surfaces) of embeddedelement 14, etc.), etc. - By fusing reinforcing
element 15 with embedded element(s) 14 andinsulative core 12 the strength ofpanel 10 may be increased in areas ofpanel 10 where reinforcingelement 15 is present. Increasing the strength ofpanel 10 in such areas ofpanel 10 facilitates having athinner insulative core 12 in those areas ofpanel 10. For example, it may be desirable to have a thinner insulative core 12 (non-limiting): -
- along an interior edge of
panel 10 to facilitate flush mounting of the panel against a structural post (e.g. as shown inFIG. 1 B insulative core 12 is thinner inregion 17 facilitating flush mounting of the panel against a structural post (the structural post may abut embeddedelement 14B proximate to region 17); - along an interior edge of
panel 10 to facilitate flush mounting of the panel against roof trusses, roofing panels or other roof assemblies and/or the like (e.g. a parapet portion ofpanel 10 which may be adjacent a plurality of roof trusses may be thinner than the remaining wall portion ofpanel 10 below the roof trusses (see e.g.FIGS. 1A and 1C which illustrateupper portion 18 ofpanel 10 having a thinner insulative core)).
- along an interior edge of
-
Insulative core 12 may, for example, be about 5%-35% thinner in areas where reinforcingelement 15 is present compared to areas ofinsulative core 12 where reinforcingelement 15 is not present. In some embodiments insulativecore 12 may be about 5%-80% thinner in areas where reinforcingelement 15 is present compared to areas ofinsulative core 12 where reinforcingelement 15 is not present. In some embodiments insulativecore 12 is about 50% thinner in areas where reinforcingelement 15 is present compared to areas ofinsulative core 12 where reinforcingelement 15 is not present. In some embodiments insulativecore 12 is about 75% thinner in areas where reinforcingelement 15 is present compared to areas ofinsulative core 12 where reinforcingelement 15 is not present. - In some embodiments an interior edge of
panel 10 is custom shaped to match the profile of a post, beam or other structural element against whichpanel 10 will be flush mounted whenpanel 10 is installed. - The cementitious layer on
face 10A ofpanel 10 may comprise a decorative pattern (see e.g.FIG. 1A which illustrates a plurality of decorative grooves 19).Face 10A of eachpanel 10 may, for example, correspond to a corresponding portion of the exterior of a building being constructed. As described elsewhere herein,panels 10 may generally be installed as exterior wall panels of a building under construction. However it is not necessary thatpanel 10 correspond to an exterior wall panel in all cases. -
FIGS. 2A and 2B are perspective views of an example single storycommercial building 20 which comprisespanels 10. Althoughpanels 10 may be used in the construction of a single storycommercial building 20,panels 10 may also be used for other buildings as well and should not be limited to the example case illustrated inFIGS. 2A and 2B . -
FIG. 3 is a block diagram illustrating anexample method 21 of erectingexample building 20. - In block 22 a plurality of prefabricated brace-bay panels (e.g. brace-bay panels 30) are coupled to a pre-built foundation 36 (see e.g.
FIG. 3A ). The brace-bay panels comprise a finished exterior surface as well as embedded structural elements (e.g. structural posts, beams, cross-bracing, etc.). The brace-bay panels are load bearing and may assist with dissipating shear forces (e.g. wind forces, seismic forces, etc.) which may be exerted on building 20. In some embodiments at least one brace-bay panel is placed on each side of building 20 to assist with dissipating shear forces exerted on building 20. - The more load bearing panels (e.g. brace-bay panels) a building comprises, the more uplift on a foundation of building 20 may be limited, enabling reduction of structural connections between building components and the foundation and/or the like. For example, the more load bearing panels are installed in a building the amount or size of anchor rods that are required to be installed within the foundation at points where structural posts are coupled to the foundation may be reduced (e.g. less anchor rods, smaller diameter anchor rods, shorter length anchor rods and/or the like). In some embodiments at least all of the exterior wall panels of a building are load bearing. In some embodiments all of the wall panels of a building are load bearing. In some embodiments all of the load bearing wall panels comprise brace-bay panels.
- In some embodiments building 20 comprises 10 or fewer brace-bay panels. In some embodiments building 20 comprises about 6 brace-bay panels. In some embodiments building 20 comprises 5 or fewer brace-bay panels. In some embodiments building 20 comprises at least one brace-bay panel. In some embodiments building 20 comprises greater than 20 brace-bay panels.
- In some embodiments a building comprises alternating load-bearing panels (e.g. brace-bay panels) and non-load-bearing panels (e.g. every second panel is a load-bearing panel).
Cladding panel 10 is one example of a non-load-bearing panel. In some embodiments non-load-bearing panels such ascladding panel 10 may comprise cross-bracing or other similar embedded structural elements. Such cross-bracing may increase the structural strength of the non-load-bearing panels thereby requiring less underlying support structure. In some embodiments acladding panel 10 which comprises at least one embedded structural element may at least partially support load of the building it is installed in. - The
pre-built foundation 36 may be constructed using any present or future construction practice for making building foundations. For example, concrete may be poured into forms to construct the foundation. A concrete base pad may then be poured over the foundation. As another example, a foundation may be assembled using prefabricated panels. As another example, a foundation may be based on pilings which have been inserted into the ground. - In
block 23 vertical structural posts (posts 31) are coupled to the pre-built foundation.Structural posts 31 may comprise steel posts or the like. Typically the distance between twoadjacent posts 31 matches the width of apanel 10 which will be installed between the two adjacent posts. - In
block 24 structural rim beams 32 are coupled to posts 31. Structural rim beams 32 may, for example, comprise steel beams such as steel “I” beams. Rim beams 32 may support (e.g. provide a ledge, etc.) a roof of the building and/or transfer forces from the roof onto other components of the underlying structure of a building (e.g. posts, columns, etc.) to the foundation of the building. -
FIG. 3B illustrates the coupling ofstructural posts 31 and rim beams 32 to building 20. -
Trusses 33 may be coupled to rim beams 32 in block 25 (see e.g.FIG. 3C ).Trusses 33 may, for example, comprise steel trusses. In some embodiments trusses 33 comprise wood beams or the like. The number oftrusses 33 may be dependent on the width ofroof panels 34 which will be coupled to trusses 33. Thewider roof panels 34 are, thefewer trusses 33 may be required in some cases. - In
block 26exterior cladding panels 10 are coupled tostructural posts 31 and rim beams 32 to form the exterior walls of building 20 (see e.g.FIG. 3E ). In somecases panels 10 are coupled flush againststructural posts 31 and rim beams 32 (e.g. an interior wall formed bypanel 10 is flush with an interior surface ofpost 31 and/or beam 32). In somecases panels 10 hang from one or both ofpost 31 andrim beam 32. For example, apanel 10 may comprise a header panel. The header panel may be coupled to hang from rim beam 32 (e.g. using angle connectors (e.g. L shaped connectors) or the like). - In some
cases panel 10 comprises a sill panel. The sill panel may be coupled to the pre-built foundation of building 20. For example, the sill panel may be coupled to the pre-built foundation of building 20 using angle connectors (e.g. L shaped connectors) or the like. - Although
panels 10 have been illustrated as being installed inblock 26,panels 10 may be installed at any time after rim beams 32 have been installed. In some cases installation ofpanels 10 is not continuous and other elements of building 20 may be installed intermittently. For example, trusses 33 orroof panels 34 may be installed intermittently between installation of twopanels 10. In somecases roof panels 34 are installed prior to installing cladding panels 10 (e.g. as shown inFIGS. 3D and 3E ). - A roof may be installed in block 27 (see e.g.
FIG. 3D ). Typically the roof comprises a plurality ofpre-fabricated roof panels 34. However, this is not mandatory in all cases. In some embodiments a conventional roof is installed (e.g. a base is built overtrusses 33 and the base is covered with a roofing material such as an asphalt membrane, shingles, a steel roof, etc.). - Windows and/or doors may be installed in
block 28. In some cases however windows and/or doors are installed upon acorresponding panel 10 being installed. In some cases windows and/or doors are pre-installed withinpanels 10. Any remaining fixtures (awnings, canopies, decorative towers (e.g.decorative tower 37 shown inFIG. 3F ), etc.) may be installed inblock 29. - As described elsewhere herein,
panels 10 may be coupled tostructural posts 31. In some embodiments apanel 10 may be coupled to acorresponding post 31 as shown inFIG. 4A . A top end ofpanel 10 pay be coupled to a top end ofpost 31 with aconnector 41.Connector 41 may comprise aslot 42 as shown inFIGS. 4B and 4C . A bolt or other fastener may pass through an aperture ofpost 31 andslot 42 to couple the top end ofpanel 10 to post 31. - As shown in
FIGS. 4B and 4C connector 41 (or any other connector of panel 10) may be coupled to one or more embeddedelements 14. For example, a connector may be coupled to embeddedelements 14B. In some embodiments a connector is coupled to an embeddedelement 14 with bolts or other fasteners (e.g. bolts 48 shown inFIG. 4C ). - A bottom end of
panel 10 may be coupled to a corresponding bottom end ofpost 31 with aconnector 43.Connector 43 may be the same asconnector 41 or different. - In some embodiments a middle portion of
panel 10 may also be coupled to post 31 with aconnector 45 as shown inFIG. 4A . This is not mandatory in all cases.Connector 45 may comprise a slot through which a bolt or other fastener may pass through to couple the middle portion ofpanel 10 to post 31. - As described elsewhere herein, in some embodiments one or more of the connectors (
e.g. connectors e.g. connectors -
FIGS. 4D and 4E illustrate anexample post 31. -
FIG. 4F illustrates an example coupling of apanel 10 to a top portion ofpost 31. As another example,FIG. 4G illustrates an example coupling of a top part of apanel 10 to apost 31.FIG. 4H illustrates an example coupling of apanel 10 to a bottom portion ofpost 31.FIG. 4I illustrates an example coupling apanel 10 to a middle portion ofpost 31. - One or more of
connectors FIG. 4H ). - A connection of
panel 10 to a post 31 (e.g. via a corresponding plate on the post and a corresponding connector on the panel) may comprise at least one bolt or other fastener passing through a slot. Such bolt and slot coupling may permit movement ofpost 31 relative topanel 10. The slot may be part of the connector ofpanel 10, part of the corresponding plate ofpost 31 or part of both the connector ofpanel 10 and the corresponding plate ofpost 31. - Advantageously, the slots of the connections between
panels 10 to an underlying structure of building 20 may permit members of the underlying structure of building 20 (e.g. apost 31, etc.) to pivot relative to panel(s) 10 during a seismic event (or other exertion of force on building 20) or the like as shown in, for example,FIG. 4J . Permitting pivoting of members of the underlying structure of building 20 relative to panel(s) 10 improves and maintains the structural integrity of building 20 during and after a seismic event (or upon the exertion of any other force (or forces) which may cause an underlying structure of building 20 to move relative to panels 10). For example, a gap (e.g. gap 47 shown inFIG. 4A ) may be intentionally left betweenpanel 10 and post 31 such that post 31 can pivot relative topanel 10. In some embodiments the gap is less than about 1 inch. In some embodiments the gap is less than about 0.5 inches. - In some
embodiments connector 43 also comprises a slot which permits movement ofpanel 10 relative to post 31. -
FIG. 4K illustrates an example of a panel 10 (e.g. a sill panel) which is coupled toposts 31 with angle connectors. As another example,FIG. 4L illustrates an example of a panel 10 (e.g. a header panel) which is coupled to an underlying structure of building 20 with angle connectors.FIG. 4M illustrates an example of apanel 10 which is coupled to apost 31 with an angle connector and an OrbiPlate™ coupling. - In some embodiments a
panel 10 comprises at least one post (e.g. post 31) embedded within the panel. In some such embodiments rim beams (e.g. rim beams 32) and/or trusses (e.g. trusses 33) are exposed elements of a building. -
FIG. 5A is a perspective view of an example load-bearing panel such as brace-bay panel 30.FIG. 5B is an exterior front view of brace-bay panel 30.FIG. 5C is an interior back view of brace-bay panel 30.FIGS. 5D and 5E illustrate cross-sectional and exploded views respectively of example brace-bay panel 30. - Brace-
bay panel 30 comprises an embeddedstructural frame 50 comprisingposts 51, aheader beam 52 and cross-bracing 53 (optional). Different embodiments ofpanel 30 may not comprise all ofposts 51,beam 52 andcross-bracing 53.Posts 51 may be like structural posts 31.Header beam 52 may be likerim beam 32. Cross-bracing 53 may comprise any cross-bracing betweenposts 51 andheader beam 52. In the illustratedembodiment cross-bracing 53 comprises two beams (53A and 53B) which are diagonally arranged relative to one another to form an “X” like shape. In some embodiments cross-bracing 53 comprises beams 53A and 53B arranged in a chevron pattern (e.g. an upside down “V”). In some embodiments cross-bracing 53 comprises a single beam. In some embodiments cross-bracing 53 comprises three or more beams. - In some embodiments cross-bracing 53 may move freely relative to any cementitious layer of panel 30 (
e.g. cross-bracing 53 may freely move during a seismic event relative to the cementitious layers which may cover panel 30). Allowingcross-bracing 53 to move freely may advantageously preserve the structural integrity of building 20, avoiding damage topanel 30 and/or the like. -
Structural frame 50 is embedded within aninsulative core 54 ofpanel 30.Insulative core 54 may be likeinsulative core 12 ofpanel 10 described elsewhere herein (e.g. may comprise an EPS foam or the like).Structural frame 50 may be coupled toinsulative core 54 with a cementitious material. The same or a different cementitious material may at least partially cover one or both offaces insulative core 54. In some embodiments a cementitious material (the same or different than the cementitious material covering at least one offaces structural frame 50. Such cementitious material(s) may have any one or more of the characteristics and/or properties of cementitious materials described herein. -
Plates 55 may be coupled to bottom ends ofposts 51.Plates 55 may, for example, compriseapertures 56 through which bolts may pass through. The bolts may be inserted into corresponding apertures in the building foundation thereby couplingpanel 30 to the building foundation. - In some embodiments brace-
bay panel 30 is like claddingpanel 10 described elsewhere herein except that brace-bay panel 30 additionally comprises an embeddedstructural frame 50. - As described elsewhere herein, a plurality of
roof panels 34 may form a roof of building 20. In someembodiments roof panels 34 comprise prefabricated panels having an insulative core as described elsewhere herein (e.g. an EPS foam core or other suitable material) and at least one surface of the insulative core at least partially covered by a cementitious material. Such cementitious material may have any one or more of the characteristics and/or properties of cementitious materials described herein. In someembodiments roof panel 34 is like the panel shown inFIGS. 6A and 6B . -
FIG. 6A is a perspective view of an examplecomposite roof panel 34.FIG. 6B is a cross-sectional view ofcomposite roof panel 34. -
Panel 34 comprises an insulative core 62 (e.g. an EPS foam or other material as described elsewhere herein). Q-deck sheeting 63 may be coupled to asurface 62A ofcore 62 with acementitious material 64. In some embodiments aninner surface 63A of Q-deck sheeting 63 comprises texture features 65 (e.g. holes, bumps, ridges, etc.) as shown inFIG. 6C .Textured features 65 may facilitate bonding ofcementitious material 64 to Q-deck sheeting 63. Q-deck sheeting 63 typically comprises metal sheeting. In some embodiments Q-deck sheeting 63 comprises steel sheeting.Cementitious material 64 may have any one or more of the characteristics and/or properties of cementitious materials described herein. - In some embodiments only about ¼ inch of cementitious material between a top surface of Q-
deck sheeting 63 andsurface 62A is required to properly bond Q-deck sheeting 63 tocore 62. In some suchembodiments roof panel 34 has a total weight that is less than about 20 pounds per square foot. - In some embodiments not every trough of Q-
deck sheeting 63 is filled withcementitious material 64. For example, every second trough may be unfilled (e.g. the troughs alternate between filled and unfilled). By not filling every trough of Q-deck sheeting 63, an overall weight ofroof panel 34 may be reduced. Foam inserts (e.g. Styrofoam, EPS, etc.) or similar may be placed in the unfilled troughs.Cementitious material 64 may bond together all of Q-deck sheeting 63, the foam inserts andinsulative core 62 to form thecomposite roof panel 34. - Opposing
surface 62B ofcore 62 may be covered by a weather-resistant roofing element or roofing membrane. In some embodiments surface 62B is covered by a cementitious material. In some embodiments surface 62B is covered by a commercially available roofing membrane. In some embodiments the roofing membrane extends past outer edges ofsurface 62B of panel 34 (e.g. past two edges ofsurface 62B). Whenadjacent panels 34 are coupled together, the roofing membrane which extends past the edges ofsurface 62B may be placed oversurface 62B of theadjacent panel 34. The overlapping roofing membranes may be joined together (e.g. welded, bonded, etc.) to seal the roofing membrane. Extending a roofing element over an adjacent panel may improve the quality of the seal betweenadjacent panels 34 thereby reducing the likelihood of any leaks forming. Typically the roofing elements or portions of the membrane are sealed such that higher roofing elements or portions of the membrane are placed over lower roofing elements or portions of the membrane. In some embodiments the roofing element or membrane extends past the back and right edges of a panel 34 (not mandatory). - In some embodiments surface 62B of
insulative core 62 is shaped to direct water in a desired manner. For example,surface 62B may be sloped downwards from one end to an opposing end ofpanel 34. As another example,surface 62B may be shaped as a “V”. - In some embodiments one or
more roof panels 34 comprise one or more drainage ports to direct water away from the roof surface. In some embodiments surface 62B may be shaped to direct water towards the drainage port(s). In some embodiments surface 62B comprises a trough-like channel to direct water towards the drainage port. - In some
