DRAINAGE COLLECTION PIPE
To provide a resin-made drainage collection pipe that can exhibit an optimal fire spread prevention effect.SOLUTION: A standard drainage collection pipe 1000 includes a standard upper pipe 1100 and a standard lower pipe 1500. 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 standard lower pipe 1500 includes a lower vertical pipe connection part 1510 that connects a lower vertical pipe and is covered by an outer layer member 1700. A thermal-expansion fire-resistant material 1712 is provided on an innermost layer of the outer layer member 1700, and a height position thereof is above an upper end of the standard lower pipe 1500 (the upper end of a lower pipe socket) and below an upper end of the outer layer member 1700 (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 1
【課題】最適な延焼防止効果を発現し得る樹脂製の排水集合管を提供する。【解決手段】標準排水集合管１０００は、標準上部管１１００と標準下部管１５００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、標準下部管１５００は下立管を接続する下立管接続部１５１０を含み、外層部材１７００により覆われている。外層部材１７００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、標準下部管１５００の上端（下部管受口の上端）より上で、かつ、外層部材１７００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１
