TEMPORARY STRUCTURE DURING BASE-ISOLATION WORK FOR EXISTING BUILDING
PROBLEM TO BE SOLVED: To provide a temporary structure during a base-isolation work for an existing building, capable of reducing installation of post-installed anchors for joining the temporary structure to existing beams, by rationally dispersing a vertical pull-out force generated through a brace for bearing a horizontal external force.SOLUTION: A temporary structure during base-isolation work for an existing building, which supports a horizontal external force acting on a column-beam frame 1 while supporting a vertical column axial force, includes: a rectangular temporary brace frame 7 arranged and fixed to a pair of upper and lower existing beams 4a, 4b while leaving gaps from existing columns 3, for supporting the horizontal external force acting on the column-beam frame; temporary support posts 5 vertically arranged between the temporary brace frame and the existing columns, for supporting the vertical column axial force; and extending parts 14a, 14b provided on the temporary brace frame while being extended between the upper and lower both end parts 5a, 5b of the temporary support posts and the existing beams, for transmitting a vertical pull-out force generated by the horizontal external force in the temporary brace frame to allow the force to be supported by the temporary support posts.
【課題】水平外力を負担するためのブレースを通じて発生する上下方向の引き抜き力を合理的に分散させることにより、仮設構造を既存梁に接合するための後施工アンカーの施工を軽減することが可能な既存建物の免震化施工中の仮設構造を提供する。【解決手段】上下方向柱軸力を支持しつつ柱梁架構１に作用する水平外力を支持する既存建物の免震化施工中の仮設構造であって、既存柱３から間隔を隔てて、柱梁架構の上下一対の既存梁４ａ，４ｂに定着して設置され、柱梁架構に作用する水平外力を支持する長方形状の仮設ブレース架構７と、仮設ブレース架構と既存柱との間に立設され、上下方向柱軸力を支持する仮設支柱５と、仮設ブレース架構に、仮設支柱の上下両端部５ａ，５ｂと上下一対の既存梁との間へ延長して設けられ、水平外力によって仮設ブレース架構に生じる上下方向引き抜き力を伝達して仮設支柱に支持させる延設部１４ａ，１４ｂとを備えた。【選択図】図１
