To improve the settlement of a pipe according to the slab thickness while suppressing the cost increase and facilitate the construction management in a drain pipe structure provided in a lowermost floor slab.SOLUTION: There is provided a drain pipe structure 1 to be installed in a lowermost floor slab 20, comprising: an assembly joint 2 having a branch pipe connection portion 8 connectable to a lateral branch pipe 23 arranged above the lowermost floor slab 20 and a cylindrical lower connection portion extending downward; a curved tubular leg joint 5 connected to a horizontal main pipe 21; a connection vertical pipe 3 buried in the lowermost floor slab 20 and having a lower end connected to the leg joint 5; and a connecting joint 4 buried in the lowermost floor slab 20 and connecting the assembly joint 2 and the connecting vertical pipe 3. The outer diameter of the connecting vertical pipe 3 is smaller than the outer diameter of the lower connecting part of the assembly joint 2. The assembly joint 2 and the connecting joint 4 are connected at a position embedded in the lowermost floor slab 20, and a heat-expandable sheet is wound around the connecting joint 4.SELECTED DRAWING: Figure 1
【課題】最下階スラブに設けられる排水配管構造において、コスト上昇を抑えつつスラブ厚に応じて配管の納まりを向上させ、且つ、施工管理を容易にする。【解決手段】最下階スラブ２０に設けられる排水配管構造１である。最下階スラブ２０の上側に配置される横枝管２３と接続可能な枝管接続部８と、下方に延びる円筒状の下側接続部と、を有する集合継手２と、横主管２１と接続される曲管状の脚部継手５と、最下階スラブ２０に埋設されるとともに、下端部が脚部継手５と接続される接続縦管３と、最下階スラブ２０に埋設されて、集合継手２と接続縦管３とを接続する接続継手４と、を備え、接続縦管３の外径は、集合継手２の下側接続部の外径よりも小さく、集合継手２と接続継手４とは、最下階スラブ２０に埋設される位置で接続され、接続継手４には、熱膨張性シートが巻き付けられている。【選択図】図１
