管材の接続方法または接続構造

Connecting method or connecting structure of pipe material

Abstract

【課題】管材の接続において止水・防水する。 【解決手段】 長尺状のFEP管8の外側に挟持外筒11を螺合して、挟持外筒11の端からFEP管8を露出させて、これを支持壁1の貫通穴2内に入れ、挟持外筒11が貫通穴2の周囲の支持壁1に当接する。貫通穴2の反対側から、内筒3が入れられて上記FEP管8の内側に挿通螺合され、内筒3の端の内フランジ部4で、貫通穴2が塞がれる。この内フランジ部4の貫通穴2に面する面に、吸水して膨張する吸水膨張パッキン7が取り付けられている。上記内筒3がFEP管8に螺合したまま回転移動して、挟持外筒11の先端と内フランジ部4とで貫通穴2の周囲の支持壁1が挟持される。これにより、FEP管8の先端が、内フランジ部4の吸水膨張パッキン7に強く押しつけられ、FEP管8の先端と内フランジ部4の吸水膨張パッキン7との間が密封され止水される。支持壁1の外側のFEP管8側が地中となる。 【選択図】図1
PROBLEM TO BE SOLVED: To stop water and to perform waterproofing in connection of a pipe material.SOLUTION: A holding outer casing 11 is engaged to an outer side of a long FEP pipe 8, and the FEP pipe 8 is exposed from an end of the holding outer casing 11. The pipe is inserted into a through hole 2 of a support wall 1 and the holding outer casing 11 abuts on the support wall 1 at the periphery of the through hole 2. An inner tube 3 is inserted from an opposite side of the through hole 2, and is inserted and engaged into an inner side of the FEP pipe 8. The through hole 2 is blocked by an inner flange portion 4 at an end of the inner tube 3. A water absorption/expansion packing 7 which absorbs water and expands is attached to a face facing the through hole 2 in the flange portion 4. The inner tube 3 rotates and moves while it is engaged with the FEP pipe 8, and the support wall 1 at the periphery of the through hole 2 is sandwiched between a tip of the holding outer casing 11 and the inner flange portion 4. Thus, the tip of the FEP pipe 8 is strongly pushed to the water absorption/expansion packing 7 and a part between the tip of the FEP pipe 8 and the water absorption/expansion packing 7 of the inner flange portion 4 is sealed, and water is stopped. An FEP pipe 8-side on an outer side of the support wall 1 is in the ground.
