1. A concrete building structure comprising:
a first cross-brace section, including a plurality of equidistant and spaced apart, pre-cast concrete blocks connected in series by at least one rebar, extending generally a length of a floor in the building structure; a second cross-brace section, including a plurality of equidistant and spaced apart, pre-cast concrete blocks connected in series by at least one rebar, extending generally perpendicularly to said first cross-brace section and spanning a width of the floor in the building structure, such that said first cross-brace section and said second cross-brace section form a grid understructure; a first channel surrounding at least a portion of adjacent blocks of the first cross-brace section and a second channel surrounding at least a portion of adjacent blocks of the second cross-brace section, the adjacent blocks of the first cross-brace section oriented perpendicular to the adjacent blocks of the second cross-brace section, wherein an intersection is formed at a location where the first channel intersects the second channel, whereby said grid understructure includes the first and second channels running along a length and width of the grid understructure into which concrete may be poured at a building site, each of said plurality of blocks positioned within respective first and second channels; a plurality of pre-cast concrete slabs resting atop said blocks in said grid understructure, wherein each of said pre-cast concrete slabs is supported by the first cross-brace section and by the second cross-brace section, said pre-cast concrete slabs spaced apart from each other such that concrete may be poured between adjacent concrete slabs; and, poured concrete filling each of said first and second channels and the space between adjacent concrete slabs to complete a generally flat floor of the building structure. |
