JOINT ERROR ADJUSTMENT MECHANISM AND JOINT
To provide an error adjustment mechanism for a joint connecting concrete members which can reduce the workload at a work site and increase the tolerance for construction error.SOLUTION: A joint 1 having an error adjustment mechanism comprises: a first member 10 embedded in a first concrete member 91;and a second member 30 embedded in a second concrete member 92. The first member 10 includes: a first shaft member 11 having a projection area 11B; a sheath 12 surrounding the outer peripheral surface of the first shaft member 11 at intervals so as to expose an exposed area 11C including the projection area 11B; a pregrout material 13 disposed between the outer peripheral surface of the first shaft member 11 and the sheath 12; and a buffer material 14 disposed so as to surround the outer peripheral surface side of the exposed area 11C adjacent to the protrusion area 11B and having a smaller elastic coefficient than the sheath 12. The second member 30 includes: a second member connection part 40 that can be connected to the protrusion area 11B of the first shaft member 11.SELECTED DRAWING: Figure 1
【課題】作業現場での作業量を低減するとともに、施工誤差の許容量を大きくすることが可能なコンクリート部材同士を接続する継手の誤差調整機構を提供する。【解決手段】誤差調整機構を備える継手１は、第１のコンクリート部材９１に埋め込まれる第１部材１０と、第２のコンクリート部材９２に埋め込まれる第２部材３０と、を備える。第１部材１０は、突出領域１１Ｂを有する第１の軸部材１１と、突出領域１１Ｂを含む露出領域１１Ｃを露出するように、第１の軸部材１１の外周面を、間隔を空けて取り囲むシース１２と、第１の軸部材１１の外周面とシース１２との間に配置されたプレグラウト材１３と、突出領域１１Ｂに隣接する露出領域１１Ｃの外周面側を取り囲むように配置され、シース１２よりも弾性係数が小さい緩衝材１４と、を含む。第２部材３０は、第１の軸部材１１の突出領域１１Ｂと結合可能な第２部材結合部４０を含む。【選択図】図１
