Abstract
Abstract An improved building system of the type having modular sections comprised of a foam-type insulation between skins is made by extending the skins beyond the end of the insulation and forming flanges upon such extensions. The flanged extensions of two wall sections to be joined are brought together and a resilient extrusion is installed around the flanges, thus forming a channel defined by the ends of the insulation, the flanged extension and the extrusion itself. This channel is ''''foamed-in'''' with more insulating material to form a rigid structure.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
276 words
In a building construction formed at least in part of thermally insulating panels each formed of a pair of parallel skins and an intervening layer of insulating material, means for joining two such panels in edge-to-edge relationship comprising in combination, a flange at each edge of said skin interiorly of the panel and formed by the folding of said edge back upon the skin at an acute angle relative thereto, a pair of separate resilient joining members each adapted to engage the Adjoining skins on a respective one of the sides of the two panels to be joined, each said resilient joining member extending over the full length of the edges of said panels being joined, each said resilient joining member comprising: a. a central core portion of outwardly diverging cross section lying between and abutting over at least a portion of its opposed surfaces the opposed flanges of the skins on the respective panels to be joined, said central core portion being provided on its outwardly diverging sides with at least one protruding cam element for forcing said joining member inwardly of said joined panels when the panels to be joined are urged toward each other, b. a first end portion integrally formed with said central core portion at one end thereof and adapted to flushly fit against the juxtaposed skins on the outside of the panels being joined, c. and a pair of wing portions each also integrally formed with said central core portion at the other end thereof and each adapted to slide and fit behind a respective one of the flanges of the juxtaposed skins internally of the panels to be joined.
Claim 2
Dependent Claim

In a building construction formed at least in part of thermally insulating panels each formed of a pair of parallel skins and an intervening layer of insulating material, means for joining two such panels in edge-to-edge relationship comprising in combination, a flange at each edge of said skin interiorly of the panel and formed by the folding of said edge back upon the skin at an acute angle relative thereto, a pair of separate resilient joining members each adapted to engage the Adjoining skins on a respective one of the sides of the two panels to be joined, each said resilient joining member extending over the full length of the edges of said panels being joined, each said resilient joining member comprising: a. a central core portion of outwardly diverging cross section lying between and abutting over at least a portion of its opposed surfaces the opposed flanges of the skins on the respective panels to be joined, said central core portion being provided on its outwardly diverging sides with at least one protruding cam element for forcing said joining member inwardly of said joined panels when the panels to be joined are urged toward each other, b. a first end portion integrally formed with said central core portion at one end thereof and adapted to flushly fit against the juxtaposed skins on the outside of the panels being joined, c. and a pair of wing portions each also integrally formed with said central core portion at the other end thereof and each adapted to slide and fit behind a respective one of the flanges of the juxtaposed skins internally of the panels to be joined.
Claim 3
Dependent Claim
47 words
The combination of claim 1 wherein the space between said skins at the region of the joint between two adjoining panels is filled with polyurethane foam which exerts a force against said wing portions to bring them into intimate contact with the respective flanges of said skins.
