することができる。 In Figures 1 and 2, the reference numeral 6 indicates the synthetic resin inner tube 1.
This is an intermediate layer such as a synthetic resin foam material interposed between the outer tube 2 made of an inorganic coagulant and the outer tube 2 made of an inorganic coagulant, and is adhered to the synthetic resin inner tube 1 with a synthetic resin adhesive. The intermediate layer, such as the foamed material, absorbs the expansion and contraction of the inner pipe in the radial direction, but the intermediate layer can be omitted when the degree of expansion and contraction of the inner pipe during use as a sewage drainage pipe is small.

Instead of joining the inner pipe with adhesive, apply a lubricant made of metal soap, water, aliphatic alcohol, etc. to the outer surface of the straight pipe insertion port and the inner periphery of the rubber ring inside the pipe joint socket. All you need to do is insert the straight pipe into the socket of the joint F.
本発明の耐火性管継手構造は上記の構成である
ので、次のような効果を有する。 Since the fire-resistant pipe joint structure of the present invention has the above configuration, it has the following effects.
耐火性管状構造体の合成樹脂製内管の温度差
に基づく軸方向の伸縮を吸収することができ
る。 It is possible to absorb expansion and contraction in the axial direction due to temperature differences in the synthetic resin inner tube of the fire-resistant tubular structure.

継手構造は破損することがなく、耐震効果があ
る。 Since the fire-resistant pipe joint structure has a pipe joint, even if there is a small bend in the axial direction at that part, for example, an angular displacement of about 5 degrees, this displacement will be absorbed, and the fire-resistant pipe joint structure will not be damaged. It has an earthquake-resistant effect.
