Abstract
A building construction panel in which first and second generally parallel and transversely opposed metal sheets are fastened together by at least two stiffeners which extend between the sheets' parallel opposed inward surfaces. The stiffeners are spaced apart from and extend generally parallel to one another over substantially the entire length of each sheet. The panel's laterally opposed edges are fastened together by separate edge closure members which extend generally parallel to the stiffeners. One end of each closure member is fastened along the laterally opposed edges of the first sheet, and the closure members' transversely opposed ends are fastened along the laterally opposed edges of the second sheet. The closure members are formed with at least one step extending between the closure members' transversely opposed ends. The closure member steps are sized and shaped for flush mating engagement with one another. Accordingly, any two panels can be connected together along their adjacent edges by flush mating engagement of the closure member step on one panel's edge with the closure member step on the other panel's edge.
Description
BUILDING CONSTRUCTION PANEL
Technical Field This invention pertains to metal-skinned foam-filled building construction panels having at least two internal stiffeners which are spaced apart to allow the panel to be notched without substantially impairing the panel's structural integrity.
Background Metal-skinned foam-filled panels are commonly used in building construction. One of two different framing techniques are conventionally employed in constructing a multi-storey building such as a house or condominium. In the "non-balloon" framing technique illustrated in Figure 1, a first horizontally extending truss l0A is laid on top of two or more upright, laterally opposed prior art construction panels 12 (only one of which is shown). Additional upright prior art construction panels 14 (only one of which is shown) are placed on top of truss 10, then a second horizontally extending truss lOB is laid on top of panels 14, etc. Building code regulations require that a vapour barrier 16 be applied over the entire internal surface of each construc-tion panel 12, 14 constituting an outer wall of the building. This non-balloon framing technique makes it difficult to reliably seal vapour barrier 16 against air and/or moisture penetration at the butt joints 18 between the ends of panels 12, 14 and trusses 10A, IOB.
The present invention overcomes the foregoing disad-vantage by providing a building construction panel 20 (Figure 2) having sufficiently high structural integrity that panel 20 may be notched as shown at 22 to receive truss lOC along the entire length of truss IOC. Thus, instead of using two or more vertically aligned panels 12, 14 as in the non-balloon framing technique, one may employ a single notched panel 20 to span two or more stories via a "balloon" framing technique. The notched panel-truss joint 24 can easily be sealed against air and/or moisture penetration by inserting a specially formed metal trim piece 26 into notch 22 before the end of truss lOC is inserted into notch 22. Such trim pieces have been used in prior art vapour barrier systems to provide the desired sealing functionality with respect to vapour barrier 16 which is overlaid on the internal surface of panel 20.
Summary of Invention The invention provides a building construction panel in which first and second generally parallel and transversely opposed metal sheets are fastened together by at least two stiffeners which extend between the sheets' parallel opposed inward surfaces. The stiffeners are spaced apart from and extend generally parallel to one another over substantially the entire length of each sheet.
The panel's laterally opposed edges are fastened together by separate edge closure members which extend generally parallel to the stiffeners. One end of each closure member is fastened along the laterally opposed edges of the first sheet, and the closure members' transversely opposed ends are fastened along the laterally opposed edges of the second sheet. The closure members are formed with at least one step extending between the closure members' transversely opposed ends. The closure member steps are sized and shaped for flush mating engagement with one another. Accordingly, any two panels can be connected together along their adjacent edges by flush mating engagement of the closure member step on one panel's edge with the closure member step on the other panel's edge.
Advantageously, the stiffeners can be perforated to allow foam insulation material injected between the sheets in liquid form to flow throughout the spaces between the sheets, stiffeners and edge closure members prior to hardening. The transversely opposed ends of the stiffeners and the closure members preferably extend generally parallel to the sheets.

Description Figures 3-5 depict a building construction panel 30 in accordance with the present invention. Panel 30 incorporates first and second metal sheets 32, 34 which extend generally parallel and in transverse opposition to one another. Either or both of sheets 32, 34 may be stiffened by roll-formation of corrugations therein, as shown in the case of sheet 34. The corrugations are formed such that angle 8 (Figure 3) is about 110°. At least two, and preferably three stiffeners 36, 38, 40 are fastened to and extend between the parallel, opposed inward surfaces 42, 44 of first and second sheets 32, 34. Stiffeners 36, 38, 40 are spaced apart from and extend generally parallel to one another over a substantial length portion 46 (Figure 5) of each of sheets 32, 34.
The laterally opposed gaps between the transversely opposed outward ends of sheets 32, 34 are closed by first and second edge closure members 48, 50. More particularly, first edge closure member 48 is formed with transversely opposed first and second ends 52, 54 which extend generally parallel to first and second sheets 32, 34. At least one step or tier 56 is formed in first edge closure member 48 between first and second ends 52, 54. First end 52 extends gen-erally parallel to stiffeners 36, 38, 40 in length direction 46 along first edge 58 of first sheet 32. Second end 54 is fastened (for example, by stitch welding) to and extends generally parallel to stiffeners 36, 38, 40 in length direction 46 along first edge 60 of second sheet 34. First edge 60 of second sheet 34 is transversely opposed to and positioned laterally inwardly of first edge 58 of first sheet 32, by a distance equivalent to the dimension between first edge closure member's first and second ends 52, 54.
Second edge closure member 50 is formed with transver-sely opposed first and second ends 62, 64 which extend generally parallel to first and second sheets 32, 34. At least one step or tier 66 is formed in first edge closure member 50 between first and second ends 62, 64. First end 62 extends generally parallel to stiffeners 36, 38, 40 in length direction 46 along second edge 68 of first sheet 32.
Second end 64 is fastened (for example, by stitch welding) to and extends generally parallel to stiffeners 36, 38, 40 in length direction 46 along second edge 70 of second sheet 34. Second edge 70 of second sheet 34 is transversely opposed to and positioned laterally outwardly of second edge 68 of first sheet 32, by a distance equivalent to the dimension between second edge closure member's first and second ends 62, 64.
As best seen in Figure 4, first and second edge closure members 48, 50 are sized and shaped for flush mating engagement with identical edge closure members provided on additional panels 30A, 30B identical to panel 30. Thus, the right (as viewed in Figure 4) edge of panel 30A can be connected to the left edge of panel 30 by positioning panel 30A's edge connector SOA in flush mating engage-ment with panel 30's edge connector 48. Self tapping screws (not shown) can then be driven through first end 52 of edge connector 48 into the adjacently overlapped portion of edge connector SOA to secure panels 30, 30A along their adjacent edges. Similarly, the left (as viewed in Figure 4) edge of panel 30B can be connected to the right edge of panel 30 by positioning panel 30B's edge connector 48B in flush mating engagement with panel 30's edge connector 50. Self tapping screws (not shown) can then be driven through first end 62B
of edge connector 48B into the adjacently overlapped portion of edge connector 50 to secure panels 30, 30B along their adjacent edges.
The above-described "shiplap" type edge interconnection of panels 30A, 30, 30B provides improved stress resistance in com-parison to prior art panels having tongue-and-groove type inter-connections, particularly improving the capability of panels 30A, 30, 30B to resist stresses imposed by movement of the panels under load without adversely increasing the weight of the panels or impairing the panels' ability to span substantial horizontal distances (at least eighteen feet) .
If desired, stiffeners 36, 38, 40 can be perforated by providing a plurality of apertures (not shown) through web portions 72 which extend between transversely opposed ends 74, 76 of each stiff ever. Such perforation facilitates even distribution throughout the space between sheets 30, 32 stiffeners 36, 38, 40 and edge closure members 48, 50 of liquid foam insulation material injected into such space using techniques and foam materials which are well known to persons skilled in the art. Stiffener ends 76 are fastened to inward surface 44 of second sheet 34 (for example, by stitch welding) prior to foam injection as aforesaid. Neither first ends 52, 62 of first and second edge closure members 48, 50 nor any of stiffener ends 74 need to be welded to inward surface 42 of first sheet 32, since the foam material's adhesive characteristic is sufficient to fasten inward surface 42 against first ends 52, 62 of first and second edge closure members 48, 50 and against stiffener ends 74 (as well as against first sheet 30, stiffeners 36, 38, 40 and first and second edge closure members 48, 50) upon curing of said liquid foam insulation material; upon curing of the foam material.
Spaced apart stiffeners 36, 38, 40 provide panel 30 with sufficient structural integrity to facilitate notching of panel 30 as shown at 78 in Figure 6. Notch 78 is cut in second sheet 34 and preferably has a depth no greater than the depth of the corrugations formed in second sheet 34. Although notch 78 transversely intersects and partially severs each of stiffeners 36, 38, 40 the stiffeners are not fully severed, thus ensuring that panel 30 retains sufficient structural integrity after notching to minimize impairment of the panel's load bearing capability.
As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifications are possible in the practice of this invention without departing from the spirit or scope thereof. For example, different gauges of galvanized or paint-coated metal can be used to fabricate first and second metal sheets 32, 34 and/or stiffeners 36, 38, 40 and/or edge closure mem-bers 48, 50 to alter the structural characteristics of panel 30 and thereby adapt panel 30 to different load bearing and building require-merits. Similarly, the depth of panel 30 (i.e. the transverse displace-ment between first and second metal sheets 32, 34) can be varied to adapt the structural characteristics and load bearing capabilities of panel 30 to different building requirements. Although three stiffeners 36, 38, 40 are preferably employed, only two stiffeners need be used in some cases without impairing the panel's structural characteristics and load bearing capabilities, having regard to the particular building into which panel 30 is to be incorporated. As a further example, one may optionally rivet second sheet 32 to each of stiffener ends 74 and/or to each of first ends 52, 62 of first and second edge closure members 48, S0. The scope of the invention is to be construed in accordance with the substance defined by the following claims.
