Abstract:
A composite building system comprising:joists supported at their ends at the same height to form a series of parallel joists, said joists having a lower flange, each of said joists spaced apart by a distance equal to or slightly greater than the length of a standard masonry block, each adjacent pair of said joists and opposing portions of said lower flanges defining a longitudinal block receiving channel; a standard masonry block laid into each of said longitudinal block receiving channels with said masonry blocks aligned transversely and defining a first row of masonry blocks, said standard masonry blocks taller than said joists with the space between adjacent transverse blocks defining a longitudinal trough; a compressible spacer having an upper support surface laid into each of said longitudinal block receiving channels against said first row of masonry blocks with the length of said compressible spacer approximately equal to the length of said standard masonry block, said compressible spacer being of a height lower than the height of said standard masonry block, said compressible spacer being of a thickness between approximately 0.375 inch and 1.000 inch; a second standard masonry block laid into each of said longitudinal block receiving channels against said first row of compressible spacers defining a second transversely aligned row of masonry blocks with the distance between said first row of standard masonry blocks and said second row of standard masonry blocks and said upper support surface of said compressible spacer defining a transverse groove, said transverse groove being of a depth approximately equal to the difference between said height of said standard masonry block and said height of said compressible spacer; a wire reinforcement disposed within said transverse grooves; and a cured grout filling said transverse grooves and said longitudinal troughs, said cured grout binding said blocks, said joists, and said wire reinforcements to form an integral concrete structure having a substantially planar upper surface.
