ABSTRACT:
A modular precast construction block system (10) with a wall subsystem (12) and a foundation subsystem (14). The wall subsystem (12) has a number of wall units (16) having cavities (40) and prestressed tension cables (58) cast therein. The wall units (16) are vertically stacked with alignment channels (42) in the top surface (28) of one wall unit (16) receiving the key portion in the bottom surface (30) of the wall unit (16) above, to form walls (26) with vertically aligned cavities (40). Threaded wall bars (24) and extension bars (74) are threaded through the cavities with a wall tensioning assembly (22) applying downward force on the wall units (16) and providing structural strength to the wall. The foundation subsystem (14) includes a variety of precast foundation members including T footing members (126), pier members (128), grade beam members (130), and column members (132). The T footing members (126) and grade beam members (130) include complementary angled pairs for creating angled and "T" joint foundation designs.
