Description
この発明の目的は、躯体スラブから床材の表面に振動が伝搬する際に生じる振動の増幅を抑えることにより、固体音の低減を図り、併せて、従来より問題とされている重量床衝撃音の増幅を抑えることにより、その低減を図ることができる乾式二重床構造を提供することにある。
前記躯体スラブの上面又は前記床材の下面に、表面形状が凹凸面となっている緩衝体を設置したことを特徴とする乾式二重床構造にある。

Claims (2)
- 躯体スラブと、この躯体スラブ上に支持脚を介して設置される床材とを備えた乾式二重床構造において、
前記躯体スラブの上面又は前記床材の下面に、これら躯体スラブ及び床材間に形成される空気層の厚みを不均一として該空気層をばねとする共振現象を抑えるための、表面形状が凹凸面となっている緩衝体を設置し、
前記緩衝体は少なくとも高さ寸法が異なる多数の緩衝ブロックからなり、これらの緩衝ブロックが配置されることにより、前記凹凸面が形成されていることを特徴とする乾式二重床構造。 - 前記床材の下面に前記緩衝体を設置する場合、前記緩衝体及び前記床材の各単位面積当たりの質量が、前記床材よりも前記緩衝体の方が十分大きく設定されていることを特徴とする請求項1記載の乾式二重床構造。
