TEMPORARY RECEIVING STRUCTURE FOR AXIAL FORCE OF EXISTING COLUMN
PROBLEM TO BE SOLVED: To provide a temporary receiving structure for axial force of an existing column enabling reduction of a size and weight compared to when having been manufactured using a section steel, the temporary receiving structure being capable of supporting large axial force exerted on the existing column during aseismic base isolation work.SOLUTION: A temporary receiving structure is for temporarily receiving axial force of an existing column 11 located above a portion where an aseismic base isolation device 20 of an existing building 10 is inserted. The temporary receiving structure comprises a pair of PC brackets 41 sandwiching the existing column 11 from both sides and having a PC steel bar 42 inserted respectively into a protrusion 41c located on both sides in a direction orthogonal to the sandwiching direction, the PC steel bar passing an outside of the existing column 11 in the direction orthogonal to the sandwiching direction, and the pair of PC brackets having tensile force applied by the PC steel bar 42. Each PC bracket 41 has a cutout part 41e recessed toward the existing column 11, between the sandwiching direction of the protrusion 41c and the direction orthogonal thereto.SELECTED DRAWING: Figure 2
【課題】形鋼で作製した場合と比較して、大きさ及び重量の低減を図ることが可能であり、免震工事の際に既存柱にかかる大きな軸力を支持することが可能な既存柱軸力の仮受け構造を提供する。【解決手段】既存建築物１０の免震装置２０が挿入される部分の上方に存在する既存柱１１の軸力の仮受け構造構造であって、既存柱１１を両側方から挟み込み、前記挟み込む方向と直交する方向の両外側部に位置する突出部４１ｃに既存柱１１の前記挟み込む方向と直交する方向における外側を通るＰＣ鋼棒４２材がそれぞれ挿通されて、ＰＣ鋼棒４２により緊張力がかけられた状態で連結された一対のＰＣブラケット４１からなる。各ＰＣブラケット４１は、突出部４１ｃの前記挟み込む方向と直交する方向の間に既存柱１１に向って凹んだ切欠部４１ｅを有する。【選択図】図２
