JOINT STRUCTURE OF TUBULAR MEMBER, TUBULAR MEMBER, AND CONSTRUCTION METHOD OF TUBULAR MEMBER
To provide a joint structure of a tubular member which can easily be connected on a job site and which has high drainage property when used as a drain pipe.SOLUTION: A joint structure 1 of a tubular member comprises: a first connection portion 20 formed at an end portion 10a of a tubular member 101; and a second connection portion 30 formed at an end portion 10b of a tubular member 102 and connected to the first connection portion 20. The first connection portion 20 includes: a plurality of first outer surface crest portions 24 protruding from an outer peripheral surface 11 of the tubular member 101 and disposed spirally; and first outer surface valley portions 25 formed between the first outer surface crest portions 24 adjacent in a pipe circumferential direction W and arranged in line in a pipe axis direction X. The second connection portion 30 includes: a plurality of second inner surface crest portions 34 protruding from an inner peripheral surface 12 of the tubular member 102 and disposed spirally; and second inner surface valley portions 35 formed between the second inner surface crest portions 34 adjacent in the pipe circumferential direction W and arranged in line in the pipe axis direction X. The first connection portion 20 is inserted into the second connection portion 30, and the second inner surface crest portion 34 is engaged with the first outer surface crest portion 24.SELECTED DRAWING: Figure 12
【課題】現場で容易に連結することが可能となり、排水パイプとして用いる際も排水性のよい管状部材の継手構造を提供する。【解決手段】管状部材の継手構造１は、管状部材１０１の端部１０ａに形成される第１連結部２０と、管状部材１０２の端部１０ｂに形成されて第１連結部２０に連結される第２連結部３０とを備える。第１連結部２０は、管状部材１０１の外周面１１から突出されて螺旋状に配置される複数の第１外面山部２４と、管周方向Ｗで隣り合う第１外面山部２４の間に形成されて管軸方向Ｘに並べて配置される第１外面谷部２５とを有する。第２連結部３０は、管状部材１０２の内周面１２から突出されて螺旋状に配置される複数の第２内面山部３４と、管周方向Ｗで隣り合う第２内面山部３４の間に形成されて管軸方向Ｘに並べて配置される第２内面谷部３５を有し、第１連結部２０が挿通されて、第２内面山部３４が第１外面山部２４に嵌合される。【選択図】図１２
