PIPING STRUCTURE AND PIPE JOINT
To reduce propagation of vibration to a building by increasing sound insulation performance and anti-vibration performance.SOLUTION: The present invention relates to a piping structure comprising a resin pipe joint 7 inserted into a slab through hole portion 15 of a floor slab 3 and a drainage pipe member (standing pipe 5) connected to a lower end of the pipe joint 7. The pipe joint 7 has an upper main body portion 21 that protrudes upward from an upper end of the slab through hole portion 15 and has a lateral branch pipe connecting portion 14, a main body intermediate portion 22 arranged in the slab through hole portion 15, and a lower main body portion 23 protruding from a lower end of the slab through hole portion 15 and connected to the drainage pipe member. The main body intermediate portion 22 and the lower main body portion 23 are covered with an inorganic fiber layer 42. The lower main body portion 23 located below a lower surface of the slab through hole portion 15 and the vicinity of an upper end of the drainage pipe member are covered with a sound insulating sheet 61. A lower portion of the inorganic fiber layer 42 on an outer peripheral surface of the lower main body portion 23 is covered with the sound insulating sheet.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のスラブ貫通孔部１５へ挿入配置される樹脂製の管継手７と、管継手７の下端部と接続された排水用管部材（立管５）と、を備えた配管構造に関する。管継手７は、スラブ貫通孔部１５の上端よりも上側へ突出し、横枝管接続部１４を有する上部本体部２１と、スラブ貫通孔部１５内に配置される本体中間部２２と、スラブ貫通孔部１５の下端から突出して排水用管部材と接続される下部本体部２３と、を備える。本体中間部２２と下部本体部２３が無機質繊維層４２で覆われる。スラブ貫通孔部１５の下面よりも下側に位置する、下部本体部２３、および、排水用管部材の上端部周辺が遮音シート６１で覆われる。下部本体部２３の外周面の無機質繊維層４２の下部が、遮音シートで覆われる。【選択図】図３
