DRAINAGE COLLECTION PIPE FOR LOWEST FLOOR
To provide a resin-made drainage collection pipe for the lowest floor that can exhibit an optimal fire spread prevention effect.SOLUTION: A drainage collection pipe 1060 for the lowest floor includes a standard upper pipe 1100 and a lower pipe 1560 for the lowest floor. The standard upper pipe 1100 includes an upright pipe connection part 1110 that connects an upright pipe and at least one horizontal branch pipe connection part 1120 that connects a horizontal branch pipe. The lower pipe 1560 for the lowest floor includes a reduced diameter part 1660 and a joint connection part 1570 that connects a leg joint that drains drainage to a horizontal main pipe directly or through another pipe, and is covered by an outer layer member 1703. A thermal-expansion fire-resistant material 1712 is provided on an innermost layer of the outer layer member 1703, and a height position thereof is above the upper end of the lower pipe 1560 for the lowest floor (the upper end of a lower pipe socket) and below an upper end of the outer layer member 1703 (the upper end of a sound insulation cover 1730). Only an upper pipe or an extension pipe exists on an inner periphery of the thermal-expansion fire-resistant material 1712.SELECTED DRAWING: Figure 9
【課題】最適な延焼防止効果を発現し得る樹脂製の最下階用排水集合管を提供する。【解決手段】最下階用排水集合管１０６０は、標準上部管１１００と最下階用下部管１５６０とを含み、標準上部管１１００は上立管を接続する上立管接続部１１１０と横枝管を接続する少なくとも１つの横枝管接続部１１２０とを含み、最下階用下部管１５６０は縮径部１６６０および横主管へ排水を流出させる脚部継手を直接または他の配管を介して接続する継手接続部１５７０を含み、外層部材１７０３により覆われている。外層部材１７０３の最内層には熱膨張性耐火材１７１２が設けられ、その高さ位置は、最下階用下部管１５６０の上端（下部管受口の上端）より上で、かつ、外層部材１７０３の上端（遮音カバー１７３０の上端）よりも下であって、この熱膨張性耐火材１７１２の内周には上部管のみまたは延長管のみが存在する。【選択図】図９
