SHEATH CONNECTION PIPE FOR PC STEEL PROTECTION AND ITS MANUFACTURING METHOD
To allow a selection between a water cut-off method of winding a tape around the circumference and a water cut-off method of attaching a seal material to an inside surface by one sheath connection pipe for PC steel protection.SOLUTION: On at least either side, an irregular shape part 2a capable of engaging with an irregular shape of a sheath for PC steel protection 10 is provided and in a seal attachment part 4 which is a connection end, a flat surface 4a on which a seal member in a ring shape 5 can be attached is formed. A notch 6 is formed in a connection side end corresponding to the flat surface 4a and the irregular shape part 2a. When the seal attachment part 4 on which the flat surface 4a is formed is cut by this notch 6, its end consists of a continuing irregular shape part 2a.SELECTED DRAWING: Figure 4
【課題】外周にテープを巻く止水方法と、内面にシール部材を貼り付ける止水方法とを１つのＰＣ鋼材保護用シース接続管で選択できるようにする。【解決手段】少なくとも一方側にＰＣ鋼材保護用シース１０の凹凸形状と係合可能な凹凸形状部２ａを有し、接続端部であるシール貼付部４には、リング状のシール部材５を貼付可能な平坦面４ａを形成する。平坦面４ａと凹凸形状部２ａとの間に対応する接続側端部には、切込用ノッチ６を形成する。この切込用ノッチ６で平坦面４ａが形成されたシール貼付部４が切断された場合、その端部は、連続する凹凸形状部２ａで構成される。【選択図】図４
