Prefabricated modular concrete foundation wall systems and methods of constructing prefabricated modular concrete foundation wall systems

DETAILED DESCRIPTION OF THE DRAWINGS Referring now more particularly to the drawings, and in the first instance to FIG.
1, wherein a preferred embodiment of the invention is disclosed, it is to be understood that the concrete form boards 10 are cast at the factory and installed in position so that the concrete footings can be cast on the job, and the form boards 10 left in position.
The excavated earth level is shown at E and, at the time the form boards 10 are placed in position, a layer of pea stone aggregate S is installed, as are the footing surrounding drain tiles T.
Once the footings 11, with appropriate steel reinforcement members in position, are poured and cured, the site is ready for the installation of the modular floor or floor system or assembly, generally designated F, with its floor modules or segments generally designated 12, and for installation of a composite wall structure or system, generally designated W, which is comprised of modular wall sections, segments, modules or panels 13 in the form of shells having dry wall paneling 14 covering insulation boards 15 which fit between the concrete end and interior studs or ribs R of each modular wall panel.
The studs or ribs, including the end studs or walls R, project inwardly from the reinforced concrete outer walls OW of each shell and are connected by similarly projecting upper sills UL and lower sills LS.
It is to be understood that the steel wire mesh reinforced floor modules 12 and the steel mesh reinforced wall modules 13 will be more particularly described later.
It is further to be understood that the wall panels 13 are connected and interlocked by mesh integrated wall connector or locking assemblies, generally designated WC, as shown more particularly in FIGS.
6-8.
In FIGS.
6 and 7, an interlocking structure for abutting panels is disclosed in which it will be noted that there is a wedge-shaped tongue and groove joint, generally designated J, provided in the abutting wall panels or shell segments 13a and 13b, the panel 13a having a vertically extending tongue portion or wall section end 13c and the panel 13b having a vertically extending recess portion or end 13d in an endmost wall section of panel 13b for receiving the tongue portion 13c
