SOUND INSULATION FLOATING FLOOR STRUCTURE AND FLOORING MATERIALS FOR CONSTRUCTION

摘要

PURPOSE: A sound insulation floating floor structure is provided to improve soundproofing, dustproofing, vibration and sound insulating efficiencies. CONSTITUTION: The sound insulation floating floor structure is formed by installing a buffer layer(12), a lightweight cellular concrete layer(13) and a finishing mortar layer(15) on a floor concrete slab(11) of a building, wherein the buffer layer(12) contains high-density blocks(17) arranged on the concrete slab(11) at regular intervals, a plate-shaped low-density sound absorber(18) installed between the high-density blocks(17), and an isolation board(19) piled on the high-density block(17) and the low-density sound absorber(18).
