Construction method for cast-in-place structure joist column replacement unloading
The invention belongs to the technical field of constructional engineering construction, and discloses a construction method for cast-in-place structure joist column replacement unloading. A working scaffold is erected on the periphery of a seriously-damaged replacement column; load calculation is carried out on the seriously-damaged replacement column; slenderness ratio checking calculation is carried out on steel supports on the periphery of the replacement column; pressure intensity checking calculation is carried out on steel used by supporting column foot base plates; steel support installation is carried out on cross beams on the periphery of the replacement column; defective concrete of the damaged replacement column is removed in a manual or small electric bush hammer chiseling mode; embedded steel bars are welded to original main bars beside main bars of the damaged replacement column; a concrete interface of the replacement column is treated; concrete pouring is carried out on a replacement column formwork through a grouting method; and after the newly-poured column is maintained, radar detection defect inspection is carried out on the compactness of the newly-poured concrete, radar detection quality detection is carried out on the joint face between the two times of concrete pouring, and the problems that the replacement column is seriously damaged and overloaded inthe construction process are solved.
本发明属于建筑工程施工技术领域，公开了一种现浇结构托梁换柱卸荷的施工方法，在受损严重的置换柱周边搭设工作脚手架；对受损严重的置换柱进行荷载计算；对置换柱四周的钢支撑进行长细比验算；对支撑柱脚垫板所使用的钢材进行压强验算；在置换柱四周的横梁上进行钢支撑安装；采取人工或小型电动凿毛机凿除的方式进行剔凿受损置换柱的缺陷混凝土；将剔凿受损置换柱主筋旁边进行植筋与原主筋进行焊接；对置换柱的混凝土界面进行处理；采用注浆法对置换柱模板进行混凝土浇筑；新浇筑的柱子进行养护后，对新浇筑混凝土密实度进行雷达检测缺陷检查和对两次浇筑混凝土之间的结合面进行雷达检测质量检测，解决了施工中置换柱受损严重、超荷载的问题。
