Abstract
Abstract This disclosure relates to a building module and to a building system wherein the module is used in the construction of low cost housing units. The module includes a fiber reinforced plastic shell having a rectangular center portion with upturned edges forming a recess which receives a lightweight foam concrete filler material. The module has window and doorway openings therethrough, and suitable reinforcing members are embedded in the foam concrete material to provide the structural strength required to meet building code specifications and for handling purposes. Preformed building modules are used to construct the exterior walls of an enclosure in the building construction system, the modules being positioned so that the plastic shell faces outwardly, thus providing a weatherproof outside surface for the enclosure. The building system further includes a foundation upon which the modules rest and to which they are secured, prefabricated interior walls and a roof, which permit the structure to be easily assembled.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
206 words
A structural building module comprising: a. a glass fiber reinforced resin shell shaped to form in a single piece an entire wall of a building enclosure, said shell having a first substantially planar surface portion and upturned peripheral edge portions defining a recess having a depth which, when added to the thickness of said shell, is equal to the desired thickness of said wall; b. aggregate means secured to the interior of said shell to provide a rough interior surface; c. means on the exterior surface of said shell forming a pattern to simulate a selected building material; d. reinforcing members secured to the interior surface of said shell; and e. a foamed cellular concrete material having a density substantially less than that of ordinary concrete filling said recess and surrounding said aggregate means so as to be bonded to said shell, said cellular concrete material and said shell forming an enclosure wall of the desired thickness to provide a structural wall module having improved strength and reduced weight, said shell forming a weather-resistant exterior surface, the upturned peripheral Edges of said shell providing the ends, top and bottom edges and the surface of said concrete material forming the interior surface of the modular wall structure.

A structural building module comprising: a. a glass fiber reinforced resin shell shaped to form in a single piece an entire wall of a building enclosure, said shell having a first substantially planar surface portion and upturned peripheral edge portions defining a recess having a depth which, when added to the thickness of said shell, is equal to the desired thickness of said wall; b. aggregate means secured to the interior of said shell to provide a rough interior surface; c. means on the exterior surface of said shell forming a pattern to simulate a selected building material; d. reinforcing members secured to the interior surface of said shell; and e. a foamed cellular concrete material having a density substantially less than that of ordinary concrete filling said recess and surrounding said aggregate means so as to be bonded to said shell, said cellular concrete material and said shell forming an enclosure wall of the desired thickness to provide a structural wall module having improved strength and reduced weight, said shell forming a weather-resistant exterior surface, the upturned peripheral Edges of said shell providing the ends, top and bottom edges and the surface of said concrete material forming the interior surface of the modular wall structure.
Claim 3
Dependent Claim
23 words
The building module of claim 1, wherein said foamed cellular concrete material has a density of approximately 50 percent that of ordinary concrete.
Claim 4
Dependent Claim
24 words
The building module of claim 1, wherein said reinforcing members secured to the interior surface of said shell are embedded in said concrete material.
Claim 5
Dependent Claim
22 words
The building module of claim 1, further including at least one opening formed in said shell and extending through said concrete material.
Claim 6
Dependent Claim
87 words
The building module of claim 4, wherein said shell further includes second upturned edge portions around the periphery of said opening and extending inwardly from said first planar surface portion to cooperate with said first-named peripheral edge portion and said first planar surface portion to define said recess, and wherein said edge portions terminate in a common plane substantially parallel to said first planar surface, said cellular concrete material filling said recess whereby the exposed surface of said concrete material is substantially coplanar with said common plane.
Claim 7
Dependent Claim
21 words
The building module of claim 5, wherein said reinforcing members substantially surround said opening and are embedded in said concrete material.
