CONSTRUCTION JOINT STRUCTURE OF UNDERGROUND CONTINUOUS WALL
PROBLEM TO BE SOLVED: To provide a construction joint structure of an underground continuous wall capable of transmitting shear force between elements, even when large in-plane shear force is exerted.SOLUTION: A construction joint structure of an underground continuous wall includes a recess 1A formed on an edge surface of a preceding element 1, a protrusion 2A formed on an edge surface of a succeeding element 2 and engaged with the recess 1A, a preceding element reinforcing bar arranged respectively on a front surface side and a rear surface side of the preceding element, such that to hold the protrusion 2A from both sides; a succeeding element reinforcing bar arranged respectively on a front surface side and a rear surface side of the succeeding element 2; and a connecting reinforcing bar 21 arranged inside the succeeding element 2. The connecting reinforcing bar 21 is arranged such that an edge part on the preceding element 1 side is positioned inside the protrusion 2A.SELECTED DRAWING: Figure 1
【課題】大きな面内せん断力が作用した場合であっても、エレメント間でせん断力を伝達することが可能な地中連続壁打継部構造を提案する。【解決手段】先行エレメント１の端面に形成された凹部１Ａと、後行エレメント２の端面に形成されて凹部１Ａと係合された凸部２Ａと、凸部２Ａを挟むように先行エレメントの表面側および裏面側にそれぞれ配筋された先行エレメント鉄筋と、後行エレメント２の表面側および裏面側にそれぞれ配筋された後行エレメント鉄筋と、後行エレメント２内に配筋された接合筋２１とを備え、接合筋２１は、先行エレメント１側の端部が凸部２Ａ内に位置するように配筋されている。【選択図】図１
