PIPE STRUCTURE BODY, AND METHOD FOR MANUFACTURING PIPE MATERIAL
To provide a pipe structure body capable of restraining deformation of pipe joint in the case of fire breaking, and reliably blocking a block penetration part by expansion of a pipe material, although heat expansion starting temperature of the pipe material is high and the pipe material is easy to be manufactured.SOLUTION: A pipe structure body 1 according to the present invention comprises a pipe joint 10 having a socket 11a, and a pipe material 20. The socket 11a and the pipe material 20 are connected to each other in a block penetration part 2a of a floor slab 2 or a wall. The pipe joint 10 contains a resin composition (A) including polyvinyl chloride base resin and a heat absorbent, and the pipe material 20 contains a resin composition (B) including polyvinyl chloride base resin and heat-expansion graphite with the heat expansion starting temperature of 240°C or more.SELECTED DRAWING: Figure 1
【課題】配管材の熱膨張開始温度が高く、配管材を作製しやすいにもかかわらず、火災発生の際には管継手の変形を抑制でき、配管材膨張によって区画貫通部を確実に閉塞できる配管構造体を提供する。【解決手段】本発明の配管構造体１は、受口１１ａを備えた管継手１０と、配管材２０とを備え、床スラブ２又は壁の区画貫通部２ａ内で受口１１ａと配管材２０とが接続されており、管継手１０は、ポリ塩化ビニル系樹脂と吸熱剤とを含む樹脂組成物（Ａ）を含有し、配管材２０は、ポリ塩化ビニル系樹脂と熱膨張開始温度が２４０℃以上である熱膨張性黒鉛とを含む樹脂組成物（Ｂ）を含有する。【選択図】図１
