STEEL PIPE JOINT STRUCTURE OF STEEL SLIT DAM, AND STEEL SLIT DAM
To provide a steel pipe joint structure of a steel slit dam with high workability, strength, rigidity, economical efficiency, and maintainability, in which a new steel pipe joint structure replacing a flange joint (a flange plate and a high-strength bolt) is developed to realize a joint structure with higher strength and rigidity than those of the flange joint without using high-strength bolts, thereby eliminating the need for bolt tightening management and minimizing damage and destruction of members due to direct hits of gravel, and to provide a steel slit dam comprising the steel pipe joint structure.SOLUTION: A first joint member 1 comprising an uneven portion 11 forming uneven steps in an axial direction of a steel pipe 10 is provided at an end of the steel pipe 10. A second joint member 2 comprising an uneven portion 22 engaging with the uneven portion 11 of the first joint member 1 is provided at an end of the other steel pipe 20. A slip-off prevention member 3 is joined at an engaging portion R between the uneven portion 22 of the first joint member 1 and the uneven portion 22 of the second joint member 2.SELECTED DRAWING: Figure 1
【課題】フランジ継手（フランジプレートと高力ボルト）に代わる新たな鋼管継手構造を開発することで、高力ボルトを用いることなく前記フランジ継手よりも強度・剛性の高い継手構造を実現することにより、前記ボルト締め付け管理も無用とし、また、前記礫の直撃による部材の損傷、破壊を極力最小限に止める等、施工性、強度・剛性、経済性、およびメンテナンス性に優れた鋼製スリットダムの鋼管継手構造および前記鋼管継手構造を備えた鋼製スリットダムを提供する。【解決手段】一方の鋼管１０の端部に、前記鋼管１０の軸方向へ凹凸の段差をなす凹凸部１１を備えた第１継手部材１が設けられ、他方の鋼管２０の端部に、前記第１継手部材１の凹凸部１１に噛み合う凸凹部２２を備えた第２継手部材２が設けられ、前記第１継手部材１の凹凸部２２と前記第２継手部材２の凸凹部２２との噛み合わせ部Ｒに抜け止め部材３が接合される。【選択図】図１
