CENTERING METHOD OF REINFORCEMENT BAR AND CENTERING INSTALLATION JIG FOR SEISMIC ISOLATION FRAME
To provide a centering method of a reinforcement bar and an installation jig excellent in rationality, work efficiency, and profitability to precisely install the reinforcement bar forming seismic isolation frame at a pinpoint on a target position by temporarily fixing it after centering on upper and lower parts and carrying it thereat.SOLUTION: A reinforcement bar 7 forming frame B constructed on a base A to install a seismic isolation device C is installed in an appropriate position after preliminary centering is performed using a centering installation jig comprising: a reinforcement bar supporting body 1 arranged with engaging means 51 freely engaging an upper centering member 2 on an upper surface plate 5; an upper centering member 2 detachably supporting an upper part 70 of the reinforcement bar 7 to be inserted in a through hole 50 in a determined centering state; and a lower centering member 3 detachably fixing a lower part 71 of the reinforcement bar 7 to be inserted in a through hole 60 in a determined centering state, after a plurality of the through holes 50, 60 are bored for appropriate positions P of the reinforcement bars 7 in the upper surface plate 5 and a lower surface plate 6 connected on a column part 4.SELECTED DRAWING: Figure 1
【課題】免震装置用架台をなす鉄筋棒を、上下で芯出しして仮固定して搬入し、目標位置にピンポイントで精度よく設置できる合理性と作業効率性、経済性に優れた鉄筋棒の芯出し設置工法と設置治具を提供する。【解決手段】柱部４で接続する上面板５と下面板６に鉄筋棒７の適正位置Ｐとなる貫通孔５０、６０を複数穿設し、上面板５には更に上部芯出し部材２を係止自在な係止手段５１を設けた鉄筋棒支持体１、及び貫通孔５０に挿通される鉄筋棒７の上部７０を芯出し状態で着脱自在に支持する上部芯出し部材２、並びに貫通孔６０に挿通される鉄筋棒７の下部７１を芯出し状態で着脱自在に固定する下部芯出し部材３とより成る芯出し設置治具を用いて、免震装置Ｃを設置するために基礎Ａ上に構築する架台Ｂをなす鉄筋棒７を、予め芯出しして適正位置に設置する。【選択図】図１
