FALSE WALL STRUCTURE
To provide a false wall allowing sound insulation performance to be improved and constraint for facilities to be installed in a space part to be reduced.SOLUTION: A false wall structure 1 is provided with partition walls 2, substrate material 3 fixed on outer sides of the false walls 2, and false walls 4 arranged on both side of the partition wall with a space therebetween through the substrate material 3. A plurality of resonance pipes 5 with a unique resonance frequency having a plurality of holes 8 formed along a longitudinal direction are attached along the substrate material 3 in a space 6 surrounded by the partition walls 2, the substrate material 3, and the false walls 4, configuring to occupy 5 to 50% cubic volume of the space 6 with the resonance pipes 5 and allowing sound insulation performance to be improved and constraint for facilities to be installed in the space 6 to be reduced.SELECTED DRAWING: Figure 1
【課題】遮音性能を向上させると共に、空間部に設置する設備の制約を少なくすることができるふかし壁構造を提供する。【解決手段】間仕切り壁２と、この間仕切り壁２の外側に固定された下地材３と、間仕切り壁の両側に間隔をあけた状態で下地材３を介して設置されたふかし壁４とを備えるふかし壁構造１である。間仕切り壁２、下地材３及びふかし壁４に囲われた空間６に、固有の共鳴周波数を有し、かつ長手方向に沿って形成された多数の孔８を有する断面円形の複数の共鳴管５を下地材３に沿わせるように取り付け、空間６に対する共鳴管５の体積専有率を５～５０％として、遮音性能の向上と共に、空間６に設置する設備の制約を少なくする。【選択図】図１
