STRUCTURE FOR CUTTING OFF NOISE BETWEEN FLOORS OF APARTMENT HOUSE BY CONSTRUCTING SOUND ABSORPTION MATERIAL WITH HEIGHT OF FINISHING CONCRETE BETWEEN FINISHING CONCRETE LAYER AND WALL BODY

摘要

Purpose a: structure, for cutting away sound between one apartment of floor, it is arranged to absorb the noise of vibration and impact transmitting from a cover a to wall body, by installing a sound-absorbing material among the cover that is formed on a slab, the slab edge being connect with 4 method wall bodies, wall body. Construction: in the slab (30) and a wall body made of the concrete for an apartment (32) that sound insulation and one are insulated, a sound-absorbing material (31) for constant thickness is laid on floor slab and the four direction far from the metope in a constant distance (d). Sound-absorbing material is inserted into the identical height that constant distance arranges concrete layer (35) to poured on the sound-absorbing material that slab is paved on floor one, arranges concrete layer and wall body is separable.
