Abstract
Abstract A building structure module in the form of a wall panel capable of load bearing constructed of glass fiber reinforced plastic resin, semicylindrical structural members for load bearing and reinforcement and foam plastic for insulation purposes with the module having fire-retardant properties and a peripheral edge channel member to enable adjacent modules to be readily interconnected. The module is constructed by employing a procedural method so that the sequential steps are performed in a production line technique to facilitate construction of the modules.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
184 words
(Amended) A building structure module comprising a facing panel of plastic material, a plurality of reinforcement members attached to the inner surface of the facing panel, foam plastic insulating material on the inner surface of the facing panel, said reinforcement members being in the form of semitubular members having the longitudinal edges thereof secured to the facing panel and having a central portion spaced away from the facing panel to rigidify the facing panel and provide loadbearing characteristics to the module, said reinforcement members being arranged in a grid pattern with the reinforcement members extending in one direction on the facing panel being continuous, said reinforcement members being filled with foam plastic insulating material, the foam plastic insulating material being disposed throughout the enclosed areas defined by the grid work of the reinforcement members and having a depth slightly less than the depth of the reinforcement members so that the crest of the reinforcement members will be exposed above the foam plastic, and a layer of glass fiber reinforced resin plastic overlying the foam plastic insulating material and tHe crest of the reinforcement members.
Claim 2
Dependent Claim

(Amended) A building structure module comprising a facing panel of plastic material, a plurality of reinforcement members attached to the inner surface of the facing panel, foam plastic insulating material on the inner surface of the facing panel, said reinforcement members being in the form of semitubular members having the longitudinal edges thereof secured to the facing panel and having a central portion spaced away from the facing panel to rigidify the facing panel and provide loadbearing characteristics to the module, said reinforcement members being arranged in a grid pattern with the reinforcement members extending in one direction on the facing panel being continuous, said reinforcement members being filled with foam plastic insulating material, the foam plastic insulating material being disposed throughout the enclosed areas defined by the grid work of the reinforcement members and having a depth slightly less than the depth of the reinforcement members so that the crest of the reinforcement members will be exposed above the foam plastic, and a layer of glass fiber reinforced resin plastic overlying the foam plastic insulating material and tHe crest of the reinforcement members.
Claim 3
Dependent Claim
38 words
The combination of claim 1 together with a peripheral channel-shaped member integral with the facing panel and the other components of the module, said channel having an outwardly facing groove for receiving a connector for connecting adjacent modules.
Claim 4
Dependent Claim
49 words
The structure as defined in claim 2 wherein said facing panel includes a gel coat layer and a layer of glass fiber reinforced plastic resin, the gel coat layer having a finish and shape to provide a desired exterior appearance to a module for use in a building structure.
Claim 5
Dependent Claim
27 words
The structure as defined in claim 3 in which said gel coat is shaped to provide a shiplap finish to the exterior surface of the facing panel.
Claim 6
Dependent Claim
30 words
The structure as defined in claim 4 wherein the interior surface of said module is formed by an interior panel flush with the inner surface of the peripheral channel member.
