WOODEN SOUND INSULATION FLOOR
To provide a wooden sound insulation floor that can improve sound insulation performance of heavy floor impact noise and can use underfloor space as an equipment piping path without increasing the overall height.SOLUTION: A wooden sound insulation floor 100 comprises a wood structural floor 10 and a double floor 20. The wood structural floor is located between upper and lower floors, and the double floor is supported on the top surface of the wood structural floor. The wood structural floor comprises small beams 12, lower floor materials 14, and upper floor joists 16. The small beams are fixed to a frame 1, 3 at both ends, extend horizontally, and are positioned parallel to each other with a first spacing W1 in the width direction. The lower floor materials are fixed to the upper surface of the small beams 12 and extend horizontally. The upper floor joists are fixed to the upper surface of the lower floor materials, extend horizontally perpendicular to the small beams, and are located parallel with a second spacing W2 separating them in the width direction. The total length of the upper floor joists is set longer than bending wavelength λb of the lower floor materials. Both ends of the upper floor joists are used as equipment piping paths separated by a third spacing W3 from the ends of the frame 1, 2 or adjacent upper floor joists.SELECTED DRAWING: Figure 1
【課題】木質系であって、重量床衝撃音遮断性能を向上でき、かつ全高を増やすことなく床懐を設備配管経路として用いることができる木造遮音床を提供する。【解決手段】木造遮音床１００は、木質系構造床１０と二重床２０を備える。木質系構造床は上下階の間に位置し、二重床は木質系構造床の上面に支持される。木質系構造床は、小梁１２、下部床材１４、及び床上根太１６を有する。小梁は、両端が躯体１，３に固定され、水平方向に延び、幅方向に第１間隔Ｗ１を隔てて平行に位置する。下部床材は、小梁１２の上面に固定され水平に延びる。床上根太は、下部床材の上面に固定され、小梁と直交する水平方向に延び、幅方向に第２間隔Ｗ２を隔てて平行に位置する。床上根太の全長は、下部床材の曲げ波長λｂより長く設定されている。床上根太の両端は躯体１，２又は隣接する床上根太の端部から第３間隔Ｗ３を隔て設備配管経路として用いられる。【選択図】図１
