Abstract
Abstract A two-span wall panel construction includes a plurality of spaced, horizontal structural girts with liner panels secured between each three adjacent girts. Horizontally extending subgirts are attached to the liner panels and exterior panels are secured to the subgirts. The adjacent, vertical liner panels are positioned in slightly spaced relationship at the end girts and the exterior panels are positioned in overlapping and unattached relationship at the end girts. Clips for holding the liner panels are secured to the end girts between the adjacent liner panels. These clips have angular flanges which pinch the adjacent liner panels against the end structural girts. External forces of predetermined magnitude cause the liner panels to deform about the middle girt as the liner panels pivot about and release from the clip flanges while the overlapping exterior panels simultaneously pivot and release at their overlapping end. An explosion release fastener can be employed to attach the liner panel to the middle girt.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
184 words
A wall panel construction comprising: A. a plurality of spaced, horizontal structural girts secured to vertical, structural columns; B. liner panels extending between each three girts with vertically adjacent panels terminating at end girts of the three in slightly spaced relationship; C. a plurality of spaced, horizontal subgirts secured to the liner panels with certain of the subgirts positioned on either side of the end girts; D. exterior panels extending between each of said three girts and connected to the subgirts with vertically adjacent panels overlapping in unattached relationship; E. a clip having angular flanges and secured to said end girts between the adjacent spaced liner panels, the flanges of said clip pinching the adjacent liner panels against the end girts; F. means to attach the liner panels to a middle girt of the three girts; whereby an external force of predetermined magnitude against the wall panel construction causes the adjacent liner panels to deform about the middle girt as the liner panels pivot about and release from the clip flanges while simultaneously the overlapping, exterior panels pivot and release at their overlapping ends.
Claim 2
Dependent Claim
184 words
A wall panel construction comprising: A. a plurality of spaced, horizontal structural girts secured to vertical, structural columns; B. liner panels extending between each three girts with vertically adjacent panels terminating at end girts of the three in slightly spaced relationship; C. a plurality of spaced, horizontal subgirts secured to the liner panels with certain of the subgirts positioned on either side of the end girts; D. exterior panels extending between each of said three girts and connected to the subgirts with vertically adjacent panels overlapping in unattached relationship; E. a clip having angular flanges and secured to said end girts between the adjacent spaced liner panels, the flanges of said clip pinching the adjacent liner panels against the end girts; F. means to attach the liner panels to a middle girt of the three girts; whereby an external force of predetermined magnitude against the wall panel construction causes the adjacent liner panels to deform about the middle girt as the liner panels pivot about and release from the clip flanges while simultaneously the overlapping, exterior panels pivot and release at their overlapping ends.
Claim 3
Dependent Claim
33 words
The wall panel construction of claim 1 wherein the attaching means comprises an explosion release fastener with a release strength from an internally applied force less than the holding strength of the clip.
Claim 4
Dependent Claim
15 words
The wall panel construction of claim 1 wherein the attaching means comprises a self-tapping fastener.
Claim 5
Dependent Claim
17 words
The wall panel construction of claim 1, said clip having a planar surface connecting the angular flanges.
Claim 6
Dependent Claim
25 words
The wall panel construction of claim 4, said clip 4, said clip secured to said end girts by a fastener extending through said planar surface.
Claim 7
Dependent Claim
24 words
The wall panel construction of claim 1, said angular flanges of said clip forming an included angle of approximately 10° with said end girts.
Claim 8
Dependent Claim
20 words
The wall panel construction of claim 1, the angular flanges of said clip joining each other at a bend line.
Claim 9
Dependent Claim
18 words
The wall panel construction of claim 1, including insulation positioned between the liner panel and the exterior panel.
Claim 10
Dependent Claim
22 words
The wall panel construction of claim 1, said exterior panels including broad, flat, exposed surfaces to precipitate failure at the predictable load.
Claim 11
Dependent Claim
98 words
In a two-span wall panel construction, including a plurality of spaced, horizontal girts, liner panels secured between each two end girts and a center girt, a plurality of spaced subgirts secured to the liner panels and exterior panels extending between said three girts, the improvement comprising: adjacent vertical liner panels positioned in slightly spaced relationship at the end girts, vertically exterior panels positioned in overlapping and unattached relationship at the end grits and clips having angular flanges secured to the end girts between adjacent spaced liner panels, said flanges pinching the adjacent liner panels against the end girts.
