TEMPORARY SUPPORT STRUCTURE FOR AXIAL FORCE OF EXISTING COLUMN AND METHOD FOR BASE ISOLATION WORK
PROBLEM TO BE SOLVED: To provide a temporary support structure for an axial force of an existing column capable of reducing the size and weight compared with the case of making it with a section steel, and supporting a large axial force applied to the existing column at the time of base isolation work.SOLUTION: A temporary support structure of an axial force of an existing column 11 existing above the portion into which a base isolation device 20 of an existing building 10 is inserted, comprises a pair of coupling brackets 40 connected in a state in which a tensile force is applied by a PC steel rod 51 and the existing column 11 is sandwiched from both sides and the PC steel rod 51 passing through the outside in a direction orthogonal to the sandwiching direction of the existing column 11 is passed through a projecting portion 41d located on both outer portions in the direction orthogonal to the sandwiching direction. Each of the coupling brackets 40 comprises a plurality of concrete blocks 41 vertically coupled to each other, and each block 41 has a cutout portion 41b recessed toward the existing column 11 in the direction orthogonal to the sandwiching direction of the projecting portion 41d.SELECTED DRAWING: Figure 1
【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４１ｄ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５１がそれぞれ挿通されて、ＰＣ鋼棒５１により緊張力がかけられた状態で連結された一対の結合ブラケット４０からなり、結合ブラケット４０は、それぞれ、複数のコンクリート製のブロック４１が垂直方向に結合されてなり、各ブロック４１は、突出部４１ｄ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４１ｂを有する。【選択図】図１
