SHORT STRUT RETAINER AND BRIDGE PIER REINFORCING METHOD EMPLOYING THE SAME
PROBLEM TO BE SOLVED: To provide a short strut retainer which improves durability without the need to be removed even in a salt damage area after a concrete structure is hardened, and a bridge pier reinforcing method employing the same.SOLUTION: A short strut retainer is fitted to an end portion or an intermediate portion of a short strut to be used for an earth retaining construction method or a cofferdam construction method, and configured to transfer an axial force of the short strut to a support structure. The short strut retainer comprises a precast mortar or precast concrete retainer body. The retainer body includes a groove in which a reinforcing-bar is buried in one direction, of which both ends protrude for a predetermined distance, which can be integrated with a new concrete structure by being added with a mechanical joint or the like and of which the end portion is opened orthogonally with the buried reinforcing-bar.SELECTED DRAWING: Figure 1
【課題】塩害地域であってもコンクリート構造物の硬化後に撤去する必要がなく、耐久性の高い切梁受け具及びそれを用いた橋脚補強工法を提供する。【解決手段】山留工法や仮締切工法に用いられる切梁の端部又は中間部に取り付けられ、前記切梁の軸力を支持構造体に伝達する切梁受け具において、プレキャストモルタル製又はプレキャストコンクリート製の受け具本体を設け、この受け具本体に、一方向に沿った鉄筋を埋設するとともに、両端を所定距離突出させ、機械式継手などで継ぎ足して新設のコンクリート構造物と一体化可能とし、且つ、この埋設された鉄筋と直交する方向に沿って端部が開放された溝を設ける。【選択図】図１
