CONSTRUCTION METHOD TO REDUCE THE FLOOR IMPACT NOISE USING MAGNESIA AND ITS HARDNER

摘要

The present invention relates to a construction method for preventing floor noises of a detached house or an apartment house using a magnesia raw material and its hardener, more specifically, to a construction method for preventing floor noises by placing the magnesia raw material, its hardener and a slurry mixed with micro bubbles into the upper part of a slab floor of upstairs using a driving means in order to form a hardened magnesium in the form of foam, which provides a soundproof effect. The construction method for preventing floor noises in the present invention includes: a step of providing the number of bubbles including micro bubbles to the inorganic magnesia raw material and its inorganic hardener; a step of providing the slurry which includes a large quantity of micro bubbles; a step of placing or constructing the slurry onto the upper part of the slab floor to prevent floor noises, which forms and hardens a massive three dimensional network structure when the large quantity of micro bubbles are included by a hydration reaction. As a result, the present invention can play a role of a soundproofing material and, at the same time, a high strength sound insulation material as it reduces noises from an external shocking sound between floors of a building through an air layer.
