Concrete building frame construction method

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S) The following relatively detailed description is provided to satisfy the patent statutes.
However, it will be appreciated by those skilled in the art that various changes and modifications can be made without departing from the invention.
The following description is exemplary, rather than exhaustive.
FIG.
1 illustrates not only the major aspects of a preferred embodiment of the apparatus of the invention, generally referred to in both FIG.
1 and FIG.
3 by the reference numeral 11, but also the method of use of the same.
Although specifics for the invention will be described in some detail with respect to the construction of structural slabs below grade level, it will be obvious which of these specifics are applicable to the construction of structural slabs above grade level.
The apparatus illustrated in FIG.
1 includes a deck form assembly 12 for supporting concrete for a structural slab.
Such assembly includes an upper platform 13 against which concrete for a structural slab to be made is poured.
As best illustrated in FIG.
3, such platform includes a raised central portion 13 to define a slab soffit, which portion is defined by a membrane formed, for example, from plywood supported by a frame made up primarily of 2.
times.
6 joists 14 which, in turn, are supported by steel bar joists 16.
Dropheads 17 are formed at each column.
The support portion of the assembly 12 also includes a pair of end I-beams 18 which support the remainder of such assembly.
Each I-beam 18 (only one of which can be seen in FIG.
2) terminates in a protective pocket 19, the purpose of which will be described in more detail hereinafter.
When the method of the invention is used for making slabs below grade structure, at a location in which significant egress of water is to be expected, e.
g.
, a coast site, a water barrier wall 21 is formed surrounding the site at which such slabs are to be made.
Such barrier wall 21 is simply a slurry wall, and in one realization of the invention in the construction of a multi-level underground garage, the wall 21 was a 3-foot thick slurry wall that was 100-feet deep
