Benefits of technology

[0010] The flexible sheet interlock is preferably composed of a sealing non-skinning and non-hardening material that has a useful life at least equal to that of the wall panels. In this manner, the integrity of the seal between the wall panels is maintained over the useful life of the panels. The most preferred sealing material is silicone or urethane. The flexible sheet interlock, being non-skinning and non-hardening, can move freely, in response to thermally induced movement of the wall panels, without failure of the seal.
[0011] The flexible sheet interlock can be pre-installed before erection of an adjacent wall panel to provide for ease and simplicity of wall panel installation and low installation costs. The flexible sheet interlock can be installed on the wall panel and folded back on itself during installation of the adjacent wall panel. After the adjacent wall panel is installed, the interlock can simply be unfolded to cover the joint between the adjoining wall panels.

Problems solved by technology

Penetration of terrestrial fluids behind the wall panels can cause warpage and / or dislocation of the wall panels, which can culminate in wall panel failure.
If the sealing material hardens or “sets up”, the sealing material can break or shear, thereby destroying the weather seal.
Third, the longevity of the sealing material should be at least as long as the useful life of the wall panels.
If a sufficient amount of fluids enter the weep holes, the gutter can overflow, leaking fluids into the wall interior.
Such leakage can cause severe damage or even panel failure.

fourth embodiment

[0042]FIGS. 6A and 6B depict a wall panel attachment system according to the second aspect of the present invention (this second aspect briefly described in the Summary of the Invention section hereinabove). The system uses a flexible sheet interlock 250 (FIG. 6B) to seal inline adjacent perimeter framing members (e.g., perimeter framing members 258a and 258b, which may correspond to one of the pairs of lower perimeter framing members 58a,b or 58c,d of FIGS. 1, 1A and 1C). At the joint or gap 284 between the perimeter framing members 258a and 258b of adjacent wall panels 54a,b (or 54c,d), a flexible sheet interlock 250 inhibits fluid migration along the joint defined by the adjacent ends 254a,b of the adjacent gutter segments (e.g., 83a,b in FIG. 6B) of the perimeter framing members 258a and 258b. The flexible sheet interlock 250 realizes this result by retaining fluids in the adjacent gutter segments 83a,b. Accordingly, the interface (e.g., 260, FIG. 7) between the flexible sheet i...

fifth embodiment

[0059]FIGS. 22-28 depict a fifth embodiment according to the third aspect of the present invention. The wedge-shaped member 306 of the previous embodiment of FIGS. 16-21) is replaced with a screw 404 (FIGS. 23-28, alternatively, screw 404a or 404b in FIG. 22) or other fastener to hold the perimeter framing member 304 (FIGS. 23-28, alternatively, perimeter framing member 304a or 304b in FIG. 22), and the attachment member 308 (FIGS. 23-28, alternatively, attachment member 308a or 308b in FIG. 22) in position on the panel member 54 (FIGS. 23-28, alternatively, panel 54n or 54p in FIG. 22). The fastener passes through the attachment member and perimeter framing member.

[0060] The steps to assemble each panel member assembly 300 of FIG. 22 are illustrated by FIGS. 23-28, with FIG. 23 illustrating the first step, FIG. 24 the second step, FIGS. 25-26 the third step, and FIGS. 27-28 the last step. Additionally, note that FIG. 22 depicts a somewhat different embodiment from that of FIGS. 23-...
