DIFFERENT DIAMETER STEEL PIPE PILE CONNECTING MEMBER AND STEEL PIPE PILE USING THE SAME
To provide a different diameter steel pipe pile connecting member that can easily cope with various diameter differences between an upper pile and a lower pile and can be manufactured at low cost, and can be easily handled for both an expanded pile and an expanded bottom pile.SOLUTION: In a different diameter steel pipe pile connecting member 1 used when connecting a large diameter side steel pipe pile 51 and a small diameter side steel pipe pile 52 vertically when the steel pipe piles having different diameters are connected vertically, a pipe end of a large diameter short steel pipe 3, to which the large diameter steel pipe pile 51 is welded, are fixed to one side of a circular flat plate 2, which is at least not smaller than the outer diameter of the large diameter side steel pipe pile 51 by all-around welding inner and outer surfaces. A pipe end of the small diameter short steel pipe 4 to which the small diameter side steel pipe pile 52 is welded is fixed to the other side surface of the circular flat plate 2 by all-around welding the inner and outer surfaces.SELECTED DRAWING: Figure 3
【課題】上杭と下杭との種々の径差に容易に対応することが可能で安価に製作でき、かつ、拡頭杭の場合にも拡底杭の場合にも対応が容易な異径鋼管杭接続部材を提供する。【解決手段】互いに径の異なる鋼管杭を上下に接続して設置される鋼管杭である場合に大径側鋼管杭５１と小径側鋼管杭５２とを上下に接続する際に用いられる異径鋼管杭接続部材１であって、大径側鋼管杭５１の外径より少なくとも小径ではない円形平板２の片側面に、大径側鋼管杭５１が溶接接続される鋼製の大径短尺管３の管端を内外面とも全周溶接固定し、円形平板２の他側面に、小径側鋼管杭５２が溶接接続される鋼製の小径短尺管４の管端を内外面とも全周溶接固定してなる。【選択図】図３
