PILE CONNECTION STRUCTURE
PROBLEM TO BE SOLVED: To provide a pile connection structure, which enables two piles to be easily connected due to a mechanical structure and enables man hour for works of civil engineering work to be reduced.SOLUTION: In a pile connection structure, pile ends 2, 2 of piles 1, 1 formed of steel pipes are connected by a short cylindrical joint 3. The pile connection structure has through holes 4, 4 perpendicular to a shaft center at the pile end 2. The joint 3 has a pair of insertion cylinder parts 6, 6, which are divided by an inner flange part 10 at an intermediate part in a shaft center direction. An open hole 5 and a screw hole 7 are formed on the insertion cylinder part 6 on the same shaft center as the through holes 4, 4 in a state where the pile end 2 is inserted in the insertion cylinder part 6. When connection between the joint 3 and the pile 1 is finished, a bolt 8 is inserted in the open hole 5 and the through holes 4, 4 and the screw hole 7; a male screw part 8A of the bolt 8 is screwed in the screw hole 7; a head 8B of the bolt 8 applies a pressure Pto an outer peripheral surface 1A of the pile 1; and the head 8B is inserted in the open hole 5 in a buried manner.SELECTED DRAWING: Figure 1
【課題】本発明は、２本の杭を機械的構造により容易に接続でき、土木工事に於ける作業の工数を削減できる杭の接続構造を提供する。【解決手段】鋼管から成る杭１，１の杭端部２，２を、短筒状の継手３にて、接続する杭の接続構造であって、杭端部２に軸心直交状の貫孔４，４を有し、継手３は、軸心方向中間部の内鍔部１０をもって区画された一対の差込筒部６，６を有し、杭端部２が差込筒部６に差込まれた状態で貫孔４，４と同一軸心上に貫通孔５とねじ孔７が、差込筒部６に貫設され、継手３と杭１の接続完了状態に於て、貫通孔５と貫孔４，４とねじ孔７に、ボルト８が挿入されて、ボルト８の雄ねじ部８Ａがねじ孔７に螺着され、さらに、ボルト８の頭部８Ｂが杭１の外周面１Ａに押圧力Ｐ０を付与し、かつ、頭部８Ｂが貫通孔５に埋没状に装入されている。【選択図】図１
