Abstract

Abstract A modular building construction system of three interrelated phases: (1) a new method for precasting monolithic concrete building modules utilizing a plurality of essentially solid or uninterrupted internal mold members which shift vertically relative to the cast structure for release; (2) a new resulting precast monolithic building module provided by said method of high strength-to-weight ratio comprising ceiling structure with integral depending wall structure that is open at the bottom, the wall structure including both external and internal walls arranged in any desired horizontal-sectional wall plan not restricted by the casting method; and (3) a multi-story building comprising a plurality of these precast modules provided by said method in stacked relationship with the ceiling structure of each but the uppermost module serving as the floor of the next module above, the monolithic relationship between the ceiling-floor structures and both external and internal walls providing a total cellular construction wherein substantially all parts of the building contribute to its structural strength.
