Prefabricated wall panels connecting system

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The invention will be described with reference to drawing figures wherein like numerals represent like elements throughout.
Referring to FIG.
1, there is shown an integrated prefabricated concrete wall system 1 made in accordance with the teachings of the present invention.
The wall system 1 includes a plurality of prefabricated concrete wall panels 10, 12, a prefabricated concrete corner finishing piece 14, and a supporting concrete slab 29.
Slab 29 is typically six to twelve inches (6"-12") in thickness.
The thickness of the slab 29 varies depending on the size of the finished structure and the makeup of the underlying ground support.
Slab construction techniques are known in the art and are very common in the Southern part of the United States.
As shown in FIG.
1, the concrete corner piece 14 has a plurality of metal fastening straps 20 projecting from the surface 15.
In the final construction, wall panels 10 and 12 are closely abutted and connected to provide a stable corner connection for the structure as shown in FIG.
2.
When abutted with the connected concrete wall panels 10 and 12, the corner piece 14 is secured by affixing the straps 20 to the interior faces of the panels 10 and 12.
Concrete screws or nails 22 are used to attach the corner piece 14 to the wall panels 10 and 12.
As shown in FIG.
2, the exterior facing portions of wall panels 10 and 12 are secured together by a plurality of L-shaped base plates 23 and 25.
The base plates 23 and 25 are bolted into preformed threaded portions molded in the side of wall panels 10 and 12.
The preformed threaded portions are integrated into the concrete form used to construct the wall panels 10 and 12 as will be discussed in greater detail later herein.
As shown in FIG.
3, in phantom, the strap 20 which secures the concrete corner piece 14 to the wall panels 10 and 12 is positioned around the vertical concrete reinforcing bar 26.
This placement of the strap 20 about the reinforcing bar 26 not only secures the strap 20, but it prevents removal of the concrete corner piece 14 from the outside
