ANEL FOR PROTECTING NOISE BETWEEN STORIES AND BOTTOM STRUCTURE FOR NOISE-PROOF USING THE SAME

摘要

A lightweight panel and a noise-proof floor structure using the same are provided to minimize noise transmission between stories by discharging noise from a noise-absorbing path to an upper part of the lightweight panel through outlets. A lightweight panel(10') comprises a shock absorbing layer(11), a lightweight concrete layer(12), and a non-asbestos cement board(13). The shock absorbing layer, the lightweight concrete layer and the non-asbestos cement board are consecutively stacked. A gap is formed when connecting two lightweight panels. The upper part of the gap is filled with a urethane binder, and the lower part of the gap is used as a noise-absorbing path. A wall shock absorbing plate(20) is integrally attached to one side of the wall. The wall shock absorbing plate is made of foam polystyrene. The outlets are formed on the wall shock absorbing plate in a vertical direction to help noise, which is collected in the noise-absorbing path through an inlet of the wall shock absorbing plate, to be discharged from the noise-absorbing path to the upper part of the lightweight panel.
