DRAINAGE PIPE JOINT
To provide a drainage piping joint having sufficient fireproof performance.SOLUTION: A drainage piping joint 100 includes: a pipe body 110 formed of one or more resin injection molded product, and including a straight pipe part 116 arranged in a through-hole of a floor slab S when installed in a building, and a diameter shrunk part 118; an upward vertical pipe connection part 120 to which a drainage vertical pipe 520 is connected; a drainage pipe connection part 130 to which a drainage vertical pipe 530 is connected; and a lateral branch pipe connection part 140 to which a drainage lateral branch pipe 510 is connected. On the outer periphery of the pipe body 110, an outer layer member 700 is provided so as to be wound thereon. On the outer peripheral face of the straight pipe part 116, a thermal expansion fireproof sheet 712 is provided, and on a recess 112 in the outer peripheral face of the diameter shrunk part 118, a thermal expansion fireproof material 612 is provided.SELECTED DRAWING: Figure 5
【課題】排水配管継手において、耐火性能を十分に発揮させる。【解決手段】この排水配管継手１００は、ひとつまたは複数の樹脂製の射出成形品で形成され、建築物に施工された際に、床スラブＳの貫通孔に配置され直管部１１６と縮径部１１８と備えた管本体１１０と、排水立管５２０を接続する上立管接続部１２０と、排水立管５３０を接続する排水管接続部１３０と、排水横枝管５１０を接続する横枝管接続部１４０とを備え、管本体１１０の外周には外層部材７００が巻き付けるように設けてあり、直管部１１６の外周面には熱膨張性耐火シート７１２が、縮径部１１８の外周面に備えるくぼみ１１２には熱膨張性耐火材６１２が、それぞれ設けられている。【選択図】図５
