CONSTRUCTION OF MAT FOUNDATION BY CONNECTING PRECAST CONCRETE FOUNDATION BEAM MEMBER AND PRECAST CONCRETE FOUNDATION BEAM JOINING MEMBER TO CONSTRUCT RISING PART OF FOUNDATION, AND INTEGRATING BOTTOM SLAB WITH JOINT PART BY CAST-IN-PLACE CONCRETE

摘要

PROBLEM TO BE SOLVED: To maintain the minimum dimensions of a precast concrete foundation beam member to reduce weight while observing statute requests for positional dimensions of material, covering depth of reinforcements, etc. and securing the specified level of allowable stress as a beam member. SOLUTION: Predetermined reinforcements are embedded in longitudinal and lateral grated shape in a precast concrete body formed in longitudinal sectional shape, and bound by binding. Particularly the reinforcements in the lateral direction are horizontally projected from both end side faces of concrete to secure a lap joint length that guarantees continuous integration by the entanglement of the reinforcements projected from both precast concrete end side faces adjacently facing when installed. The lower end projection of vertical reinforcements and shear-reinforcing bars is treated within a flattened form trowel surface, and concrete legs are provided in suitable positions to simplify the whole shape.
