FLOOR SUPPORT STRUCTURE FOR BUILDING

摘要

A floor support structure for a building having a concrete body of regular beam construction with a floor slab connected to the upper surface of the beam, wherein vibration noise added to the floor structure is distributively propagated to the body wall through a sleeper beam to increase the sound insulation effect and moreover the floor structure can be stably supported and the thickness of the floor slab can be made less than in the prior art, thereby making it possible to increase the effective height of living space, to reduce the weight of the concrete body for improving earthquake resistance and vibration control, and to reduce the cost of the building itself. To this end, a plurality of sleeper beams 5 constituting the floor structure Fr of a building are spaced side by side in a plane, with a clearance D1 defined between the sleeper beam and a floor slab Sf, and are supported at their opposite ends by a vertical body wall 2 with a clearance D2 defined between the end and the vertical body wall 2.
