METHOD FOR STOPPING PLACEMENT OF HIGH-FLUIDITY CONCRETE

摘要

PROBLEM TO BE SOLVED: To enhance the efficiency of constructing high-fluidity concrete at a vertical jointing part by inhibiting the leakage of the high-fluidity concrete at a vertical placing joint part. ;SOLUTION: High-fluidity concrete is poured into a column part 1 separated by a vertical jointing part 11-11. Since the mesh of a retaining form 10 is closed by steel plates 12, 12 and an air fence 15, high-fluidity concrete and mortar do not leak. The air fence 15 is located between the steel plate 12 and a stirrup 6 to serve as a spacer restraining the movement of the steel plate 12.;COPYRIGHT: (C)2000,JPO
