STEEL PIPE JOINT MECHANISM AND CONNECTION METHOD
PROBLEM TO BE SOLVED: To simplify a connecting structure of a pair of steel pipes and reduce cost.SOLUTION: A joint mechanism of a pair of steel pipe piles 1A, 1B comprises: an inner joint 10A, which is disposed on the steel pipe pile 1A; an inner joint 10B; an exterior joint 20, which is installed around the inner joint 10A of the steel pipe pile 1A and an inner joint 10B of the steel pipe pile 1B; and a key member 30, which prevents the pair of steel pipe piles 1A, 1B from moving relative to each other in longer direction of the steel pipe pile 1. On the exterior joint 20, openings 22 (22A, 22B) are formed in order to insert split key members 31 composing a key member 30 into key grooves. The key groove comprises: outward peripheral grooves 13 (13A, 13B), which are formed on circumferences of the inner joint 10A and the inner joint 10B, respectively, from the outer peripheral surface of the exterior joint; and inward peripheral grooves 23 (23A, 23B), which are disposed on inner periphery of the exterior joint 20 so as to face the outward peripheral grooves 13 (13A, 13B).SELECTED DRAWING: Figure 1
【課題】一対の鋼管を連結する構成の簡素化と、コストの低減を図る。【解決手段】一対の鋼管杭１Ａ，１Ｂの継手機構は、鋼管杭１Ａに設けられた内側継手１０Ａと、内側継手１０Ｂと、鋼管杭１Ａの内側継手１０Ａと鋼管杭１Ｂの内側継手１０Ｂとに跨って周設される外側継手２０と、一対の鋼管杭１Ａ，１Ｂどうしが鋼管杭１の長手方向に相対移動することを防止するためのキー部材３０とを備え、外側継手２０にはその外周面から内側継手１０Ａ及び内側継手１０Ｂのそれぞれの外周に備えられた外向き周溝１３（１３Ａ，１３Ｂ）と外側継手２０の内周に備えられた外向き周溝１３（１３Ａ，１３Ｂ）と対向する内向き周溝２３（２３Ａ，２３Ｂ）とで構成されるキー溝にキー部材３０を構成する分割キー部材３１を挿通するための開口部２２（２２Ａ，２２Ｂ）が備えられている。【選択図】図１
