A BUILDING MATERIAL OF FLOATING FLOOR STRUCTURE HAVING SOUND-PROOFING FUNCTION IN MULTIHOUSING

摘要

According to the present invention, a sound absorbing fiber board (synthetic fiber board) having excellent sound absorption and heat insulating performance is provided on the upper and lower portions of a plastic double board as a center substrate having an air layer formed thereon, by means of a rivet fastening member made of elastic rubber. Floating floor structure that maximizes the soundproofing and insulation performance by the vibration absorption by the vibration of the floor and the sound insulation and sound insulation. It relates to the floor impact sound absorbing material between the floors of the multi-family housing.;The present invention is manufactured by extrusion molding a high-density plastic resin raw material, the center board member having a first air layer in the middle portion to block the impact sound flowing from the upper layer and at the same time have a heat insulating function; It is bound to the upper and lower surfaces of the center board member, the synthetic fiber board that absorbs and extinguishes the first impact sound flowing from the upper layer; Bonding means which firmly bonds between the center board member and the synthetic fiber board, and partially protrudes from the lower synthetic fiber board to a predetermined height so as to space between the lower synthetic fiber board and the slab layer to form a second air layer. Including, but the floor plastering mortar layer and the slab layer is separated by the first air layer and the second air layer of the center board member to form a floating floor structure such that the floor is floating in the air Provide a cushioning material.;Dustproof, Soundproof, Insulation, Center Board Member, Synthetic Fiber Board, Air Layer, Floating Floor
