REINFORCEMENT STRUCTURE OF EXISTING COLUMN
PROBLEM TO BE SOLVED: To make a reinforcing layer of an existing column thinner.SOLUTION: A coupler 5x for a spiral hoop reinforcement 5b constituting a reinforcement structure part 5 is arranged between main reinforcements 5a, 5a neighboring in the circumferential direction of a bridge pier part 3. By this, the side face of the coupler 5x for the spiral hoop reinforcement 5b can be brought close to the side face of the bridge pier part 3, so that the layer thickness of the reinforcement structure part 5 can be thinner. Therefore, an impact on a structure around the bridge pier part 3 and a construction limit can be reduced. In addition, because the spiral hoop reinforcements 5b can be wound on the outer periphery of the main reinforcements 5a as the spiral hoop reinforcements are in contact with all of the main reinforcements 5a, this can increase a binding force of the spiral hoop reinforcements 5b to the main reinforcements 5a. Therefore, a shear force of the bridge pier part 3 can be improved while positions of the plurality of main reinforcements 5a are fixed firmly.SELECTED DRAWING: Figure 3
【課題】既設柱の補強層を薄くする。【解決手段】補強構造部５を構成する螺旋フープ筋５ｂ用のカプラ５ｘを橋脚部３の周方向に隣接する主筋５ａ，５ａの隣接間に配置した。これにより、螺旋フープ筋５ｂ用のカプラ５ｘの側面を橋脚部３の側面に近づけることができるので、補強構造部５の層厚を薄くすることができる。このため、橋脚部３の周囲の構造物や建築限界への影響を軽減することができる。また、螺旋フープ筋５ｂを全ての主筋５ａに接触させた状態で主筋５ａの外周に巻き付けることができるので、螺旋フープ筋５ｂによる主筋５ａに対する拘束力を増強することができる。このため、複数の主筋５ａの位置をしっかりと固定できるとともに、橋脚部３の剪断力を向上させることができる。【選択図】図３
