Abstract
Abstract A building constructed from free standing precast stress bearing will modules by placing the elements in a trench, pouring a flowable material therein, and allowing the flowable material to set. Metallic elements extending from the wall into a recess in the bottom of the wall interconnect with the flowable material in the trench to form an integral unit of the set flowable material and the wall module. For subsequent stories, the free standing precast stress bearing wall modules include a pocket in their lateral wall to provide access to the interconnection for the fastening of a plate embedded adjacent the bottom thereof and a rib extending from the top of a lower building element.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
110 words
A method of construction a building comprising the step of: excavating a series of trenches to define the location of the exterior and interior walls of said building; positioning in said trenches a plurality of precast integrally formed concrete modules of right angle configuration and of sufficient height to define load bearing walls of said building; positioning in said trenches additional precast modules of planar configuration to define additional walls of said building; connecting selected additional walls selected load bearing walls; pouring flowable material into said trenches and about the module bases and allowing it to set; and interconnecting a ceiling structure and the top ends of selected precast modules.
Claim 2
Independent Claim
110 words
A method of construction a building comprising the step of: excavating a series of trenches to define the location of the exterior and interior walls of said building; positioning in said trenches a plurality of precast integrally formed concrete modules of right angle configuration and of sufficient height to define load bearing walls of said building; positioning in said trenches additional precast modules of planar configuration to define additional walls of said building; connecting selected additional walls selected load bearing walls; pouring flowable material into said trenches and about the module bases and allowing it to set; and interconnecting a ceiling structure and the top ends of selected precast modules.
Claim 3
Dependent Claim
21 words
The method of claim 1 including the step of placing a metal cage in said trenches before positioning said precast modules.
Claim 4
Dependent Claim
47 words
The method of claim 1 wherein selected precast modules include integrally formed metallic elements extending from their top, said ceiling structure being interconnected to said precast modules by receiving said metallic elements in aperture in said ceiling structure and fastening said metallic elements to said ceiling structure.
Claim 5
Dependent Claim
39 words
The method of claim 3 wherein said ceiling structure is a precast unit and said metallic elements are fastened to said precast unit by pouring a layer of flowable material onto said precast unit and allowing it to set.
Claim 6
Dependent Claim
36 words
The method of claim 1 wherein selected ones of said precast modules include integrally formed metallic elements extending therefrom adjacent their bottom and said modules are interconnected to said set flowable material by said metallic elements.
Claim 7
Dependent Claim
43 words
The method of claim 5 wherein said selected over of said precast modules have a recess in their bottom surface and said metallic elements extend into said recess, and said trench is excavated to a depth greater than that depth of said recess.
Claim 8
Dependent Claim
67 words
The method of claim 1 wherein selected ones of said precast modules include integrally formed metallic elements extending from their top and said ceiling structure being interconnected to said selected ones of said precast modules by receiving said metallic elements, and including the additional steps of positioning a second plurality of precast modules on top of ceiling structure and securing said second modules to said metallic elements.
Claim 9
Dependent Claim
37 words
The method of claim 1 wherein selected precast modules include a recess in the top edge thereof, and including the step of positioning a span in said recess between two precast modules before interconnecting a ceiling structure.
Claim 10
Dependent Claim
23 words
The method of claim 1 including leveling said trench in the area on which said load bearing wall modules are to be positioned.
Claim 11
Dependent Claim
46 words
The method of claim 1 wherein said load bearing wall modules include recesses in the top edge, and said selected additional walls include shoulder portions to mate with said recesses and connecting said load bearing wall modules to said selected additional walls at the mating point.
Claim 12
Dependent Claim
22 words
The method of claim 1 wherein the width of the trench excavated is substantially greater than the width of the wall modules.
