STEEL PIPE JOINT
PROBLEM TO BE SOLVED: To provide a steel pipe joint which enables smooth positioning of a steel pipe pile and a steel pipe sheet pile at low cost.SOLUTION: A steel pipe joint comprises: a box joint 30; a pin joint 20; a rotation suppressing key 50; a bolt 15; and nuts 60, 61. The rotation suppressing key 50 is arranged in a key arranging portion 40 constituted of a box side cutout portion 40A formed in an outer peripheral edge of the box joint 30 and a pin side cutout portion 40B, and restrains the box joint 30 and the pin joint 20 from relatively rotating around a pipe axis. The bolt 15 includes: a head 16 which cannot be inserted into through holes 25, 52 formed so as to communicate in a pipe-radial direction with each other respectively in the key arranging portion 40 and the rotation suppressing key 50; and a shank 17 which can be inserted into the through holes 25, 52. The nuts 60, 61 are attached to a tip of the shank 17 penetrating the through holes 25, 52 in a state in which the nuts 60, 61 cannot be inserted into the through holes 25, 52. The bolt 15 is inserted in a manner in which the shank 17 is inserted into the through holes 25, 52 from the inside to the outside in the pipe-radial direction. The bolt 15 has a head height of 2 mm to 6 mm.SELECTED DRAWING: Figure 3
【課題】鋼管杭や鋼管矢板の円滑な建て込みを安価に可能とする鋼管継手を提供する。【解決手段】ボックス継手３０と、ピン継手２０と、ボックス継手３０の外周縁に形成されたボックス側切欠部４０Ａと、ピン側切欠部４０Ｂとから構成されるキー配設部４０に配設され、ボックス継手３０とピン継手２０とが管軸周りに相対回転することを抑止する回転抑止キー５０と、キー配設部４０及び回転抑止キー５０のそれぞれに管径方向に連通可能に形成された貫通孔２５，５２に挿通不可能な頭部１６と貫通孔２５，５２に挿通可能な軸部１７を有するボルト１５と、貫通孔２５，５２を通り抜けた軸部１７の先端部に、貫通孔２５，５２に挿通不可能な状態で取り付けられるナット６０，６１と、を備え、ボルト１５は軸部１７が、貫通孔２５，５２に対して管径方向の内から外に向けて挿通される鋼管継手であって、ボルト１５は、頭高が２ｍｍ以上６ｍｍ以下である。【選択図】図３
