FIXING STRUCTURE OF EXPANSION JOINT
To provide a fixing structure of an expansion joint capable of easily fixing the expansion joint even in a range where anchor bolts cannot be driven.SOLUTION: A fixing structure of an expansion joint 20 comprises a pressing member that is applied to an anchoring portion 23c of an expansion joint 23 that straddles a joint portion 22 between concrete structures 21 and is sandwiched between the concrete structures 21; a fixing member whose intermediate portion is fixed by an anchor bolt driven outside the anchoring portion 23c, whose base end is in contact with the concrete structure 21, and whose tip presses the pressing member to fix the anchoring portion 23c; an auxiliary pressing member fixed by the fixing member adjacent to the non-driving range of the anchor bolt; a connection pressing member 27A in the non-driving range; an auxiliary fixing member for the auxiliary pressing member provided with an auxiliary fixing bolt; an auxiliary support member 33 bridged and fixed between auxiliary fixing members; and an auxiliary pressing member 34 that presses the connecting pressing member 27A and presses and fixes the anchoring portion 23c within the non-driving range of the auxiliary pressing member 33.SELECTED DRAWING: Figure 4
【課題】アンカーボルトを打設できない範囲に対しても簡単に伸縮継手を固定できる伸縮継手の固定構造を提供する。【解決手段】伸縮継手の固定構造２０は、コンクリート構造物２１間の目地部２２に跨る伸縮継手２３の碇着部２３ｃに当てられてコンクリート構造物２１で挟む押え部材と、碇着部２３ｃの外側に打設したアンカーボルトで中間部が固定され基端部をコンクリート構造物２１に当て、先端部で押え部材を押圧し碇着部２３ｃを固定する固定部材と、を備え、アンカーボルトの非打設範囲に隣接して固定部材で固定される補助押え部材と、非打設範囲の連結押え部材２７Ａと、補助固定ボルトが設けられる補助押え部材の補助固定部材と、補助固定部材間に架け渡されて固定される補助支持部材３３と、補助支持部材３３の非打設範囲内に、連結押え部材２７Ａを押圧し碇着部２３ｃを押圧固定する補助押圧部材３４と、を備える。【選択図】図４
