PLYWOOD PANEL TYPE FLOATING FLOOR SYSTEM USING DAMPING PLYWOOD

摘要

PURPOSE: A plywood panel type floating floor system using a damping plywood is provided to reduce resonant tunneling phenomenon by forming a sound-absorbing material on an air layer. CONSTITUTION: A plywood panel type floating floor system using a damping plywood comprises a plurality of damping rubber mounts(20), a damping plywood, and an upper slab(60). The damping rubber mount is installed at the upper side of a bottom slab(50) forming the floor of a building. The damping rubber mount is formed in a short pillar shape. The damping plywood is manufactured by inserting damping materials(42) between multi-layered plywoods(41). The damping plywood is installed on the upper part of the damping rubber mount. The upper slab is poured on the upper side of the damping plywood. An air layer(30) is formed between the upper slab and the bottom slab.
