FLOOR SUPPORT STRUCTURE OF BUILDING

摘要

PROBLEM TO BE SOLVED: To minimize flexural deformation due to load applied to a floor to prevent vibration trouble of the floor while ensuring high sound insulating performance of the floor by applying bending moment in a direction to allow a sleeper beam to bend projecting upward, to the sleeper beam supported floating on a support part of a concrete skeleton in the floor support structure of a building. SOLUTION: The sleeper beam BS is unfixedly supported on upper faces of additionally placed parts 3 of a concrete skeleton F, and both ends of the sleeper beam BS are provided with horizontal support members ST. A pressing means P is provided at a lower part of each horizontal support member ST, and the pressing means P is pressed to the side face of the additionally placed part 3 through a cushioning member. Bending moment m in the direction to allow the sleeper beam BS to bend projecting upward is thereby applied to the sleeper beam BS. COPYRIGHT: (C)2005,JPO&NCIPI
