Modular building construction and erection system utilizing selectively oriented modules

Claim 1

A modular building construction intended for human habitation comprising A. a series of substantially identical four sided one piece precast and preformed concrete building modules each of which comprises a room unit of a size sufficient to permit adult humans to move freely thereabout therein, each such module being defined by 1. a pair of opposed side walls, and 2. a pair of opposed floor and ceiling panels integral with and formed as one piece with said side walls, 3. said floor and ceiling panels being integrally connected with said side walls at opposed upper and lower generally right angled corner portions of such module, 4. opposite ends of such module being generally open and unrestricted prior to assembly thereof with other modules of said series into said building construction, 5. each of such module opposite ends being defined by a series of four generally smooth edge portions of said panels and side walls which lIe generally in a single plane so that each of such module ends may be abutted against another module of said series, 6. the outer surfaces of the panels and walls which define each of said corner portions of such module being generally smooth so that each corner portion of such module may be positioned in contacting abutting engagement with another module of said series, 7. the maximum dimensions and configuration of that portion of each of said side walls of such module which lies between the inner surfaces of said floor and ceiling panels corresponding generally to the internal dimensions and configuration of the respective open ends of such module, B. the majority of adjacent alternate modules of said series being oriented generally a right angles relative to each other with the end edges of the floor and ceiling panels of one module generally contacting and abutting upper and lower corner portions of a side wall of another module, 1. said side wall of each said other module closing off substantially completely said open end of each said one module in accordance with the predetermined architectural plan for said building construction, C. foundation structure initially separate from said series of modules upon which the respective modules of said series are supported, D. securing means including guide and positioning structure interposed between said foundation structure and the respective modules of said series for securely interconnecting said modules with said foundation structure, and E. releasable connecting means for separably securing said series of modules together horizontally into an operative building assembly, 1. said connecting means being positioned at generally abutting upper corner portions of said adjacent modules, 2. each group of four abutting modules of said series having their respective generally abutting corner portions offset relative to each other to define a generally rectangular vertically extending opening therebetween, 3. and a connector fitting positioned in said opening in alignment with said releasable connecting means of said group of modules providing structure by means of which said group of modules is releasably yet securely connected therewith and with each other.
