A modular construction system (10) which is directed toward the construction of structural walls (26). The construction system (10) employs precast wall units (12) and a variety of spacer/tensioning, spacer, tensioning, and extension assemblies (14, 16, 18, and 20). The wall units (12) contain a plurality of cavities (44) and are made of concrete with side walls (36) reinforced with prestressed tension wires (48). In the process of constructing a wall (26), the wall units (12) are stacked one upon the other onto threaded wall bars (24) that extend upwardly from a foundation (22). The spacer/tensioning assembly (14) and the spacer assembly (16) provide alignment during the stacking process and also create mortar joints (52). The spacer/tensioning assembly (14) and the tensioning assembly (18) are utilized in conjunction with the wall bars (24) to tension the wall units (12) onto lower wall units (12) and the foundation (22). When stacked, the internal structure of the wall units (12) creates vertically and horizontally extending passages (85 and 86) into which grout (84) is poured to create a monolithic wall (26).

A modular construction system comprising: a plurality of block units, each said block unit being precast of concrete, each said block unit having a length, a width, a height, a top surface and a bottom surface, the length being substantially greater than the width, each said block unit further having end walls, a pair of side walls extending the length of each said block unit, and a plurality of cavity walls disposed between the pair of side walls and integral therewith, each side wall having a width and containing a reinforcement structure, each cavity wall having a height and a top surface, at least one cavity wall having a height that is less than the height of said block units, the cavity walls and the pair of side walls defining a plurality of cavities, said block units being arranged with the bottom surface of a first said block unit opposing the top surface of a second said block unit, the cavity walls of the arranged said block units defining a plurality of first passages extending the height of said block units and one or more second passages extending longitudinally between two or more cavities; and spacer means for providing a joint space between the top and bottom surfaces of said block units for placement of bonding material.
