PIPE JOINT STRUCTURE
To allow for reduction of vibration propagation to a building by improving sound insulation and vibration isolation performance of pipe joint structure.SOLUTION: The pipe joint structure is provided that comprises a resin pipe joint 7 to be inserted into and arranged in a slab through-hole portion 15 formed in a floor slab 3 and has a thermally expandable refractory material layer 16 at least in a portion located in the slab through-hole portion 15. The outer periphery of the thermally expandable refractory material layer 16 in the resin pipe joint 7 is covered with a sound and vibration insulation sheet 41 having sound insulating property and vibration insulating property. The portion of the resin pipe joint 7 located above the slab through-hole portion 15 is covered with a sound insulation sheet 46. The lower end portion of the sound insulation sheet 46 is inserted into the slab through-hole portion 15 while the lower end portion of the sound insulation sheet 46 is laminated on the outside of the upper end portion of the sound insulation and vibration insulation sheet 41.SELECTED DRAWING: Figure 3
【課題】遮音防振性能をより高めて、建物への振動伝播を減らせるようにする。【解決手段】床スラブ３に形成されたスラブ貫通孔部１５へ挿入配置される樹脂製の管継手７を備え、少なくともスラブ貫通孔部１５内に位置する部分に熱膨張性の耐火材層１６を有する管継手構造に関する。樹脂製の管継手７における熱膨張性の耐火材層１６の外周部を、遮音性および防振性を有する遮音防振シート４１で覆い、樹脂製の管継手７の、スラブ貫通孔部１５よりも上側に位置する部分を遮音シート４６で覆い、遮音防振シート４１の上端部の外側に、遮音シート４６の下端部を積層した状態で、遮音シート４６の下端部がスラブ貫通孔部１５の内部に挿入されている。【選択図】図３
