wet furrow interlayer noise isolation and sound transmission blocking layer structure ( trench) installation and the construction method .

摘要

A noise-proof structure and method of blocking interfloor noise in a multi-story building is provided to facilitate waterproof construction and block interfloor noise. A method for blocking interfloor noise in a multi-story building comprises a first step of mixing 7 weight parts of wastes of gypsum board, wood, plywood, and medium density fiber (MDF) that are discharged from industries and homes and are pulverized into chips having a predetermined size, 1 weight part of EVA chips, and 1 weight part of Styrofoam chips, and 1 weight part of kellotin and waste paper, a second step of pressure-transporting and mixing an adhesive, in which the mixture of the first step is mixed with 3 weight parts of natural latex (rubber raw solution) and 7 weight parts of water, into a home under construction at a construction site, a third step of applying the mixture of the second step to the top of a concrete slab at a thickness of 20mm to 60mm, a fourth step of spraying, compacting and hardening a hardener of mixing glacial acetic acid and water, a fifth step of naturally hardening the hardened material for about 24 hours to form a structure of blocking noise.
