Sound insulation construction method for concrete floor

Abstract

The present invention relates to a concrete floor, and particularly relates to a sound insulation construction technique for a concrete floor. A sound insulation construction method for a concrete floor comprises: a concrete base cleaning step; a floating sound insulation cushion block placing step comprising isolating walls from the floor using 20 mm thick isolation plates along the walls, and placing floating sound insulation cushion blocks in a form of a 600*600 mm grid along the walls at a distance 150 mm away from the walls; a glass sound absorbing cotton laying step: densely packing gaps between the floating sound insulation cushion blocks placed in advance to satisfy the requirements of32 kg / m<3> and 50 mm thickness; a steel plate laying step: treating slots between steel plates by means of spot welding; a waterproof film laying step: sealing lap joint positions of films using plastic adhesive tapes, wherein the plastic film at the positions of sidewalls should be upturned over a concrete pouring surface, and superfluous plastic film is cut off after concrete is poured and set; and a concrete pouring and maintaining step. The sound insulation construction method for a concrete floor is conducive to creating a relatively quiet working or living environment.
