CONNECTION STRUCTURE AND CONNECTION METHOD OF STEEL PIPE
To provide a connection structure of steel pipes using easily procurable members, which can be simply installed at low cost.SOLUTION: A connection structure (10) comprises a backing material (16) comprising steel bars disposed in a circumferential shape so as to cover an inside of a joint of one steel pipe (12) and the other pipe (14). The steel bars forming the backing material are one or a plurality of steel bars processed so as to have a predetermined curvature that substantially matches an inner face of one steel pipe. A gap between end portions of the bending-processed steel bars is closed by welding or steel piece disposition.SELECTED DRAWING: Figure 2
【課題】安価で簡単に設置することができ、調達も容易な部材を用いた鋼管の接続構造を提供する。【解決手段】一方の鋼管（１２）と他方の鋼管（１４）との継ぎ目の内側を覆うように円周状に配置された鋼棒からなる裏当て材（１６）を備えている接続構造（１０）が提供される。裏当て材を形成する鋼棒は、１本又は複数本の鋼棒を一方の鋼管の内面にほぼ合致する所定の曲率を有するように加工されたものである。曲げ加工した鋼棒の端部間の隙間は、溶接又は鋼片配置により閉塞されている。【選択図】図２
