Modular building construction system

Claim 1

A modular building construction system comprising a plurality of hexagonally shaped floor members adjacently laid in an interlocking relationship, a plurality of hexagonally shaped ceiling members, a plurality of rectangularly shaped wall members which have a length corresponding to one of the hexagonal sides of said floor members, said wall members being placed on the perimeters of said floor members to support the perimeters of said ceiling members, and a plurality of U-shaped rods embedded in the sides of said hexagonal floor and ceiling members and the vertical sides of said wall members so that a loop of said U-shaped rods is exposed, said loops serving to tie adjacent wall members and adjacent floor or ceiling members together by inserting a bar through the exposed loops that overlap when two or more wall members, or two floor or ceiling members, are abutted, wherein a longitudinal space is formed between said abutting vertical sides of said wall members and between said abutting sides of said ceiling or floor members, said longitudinal space being filled with grout after said bar is inserted through said overlapped loops, whereby horizontal forces applied to said hexagonally shaped floor or ceiling members are dispersed into the various lines of connection between said hexagonal floor or ceiling members.
