Steel structure factory building column drawing reinforcement construction method
The invention discloses a steel structure factory building column extraction reinforcement construction method, which adopts a newly added joist, an extraction column is changed into a three-joint on the newly added joist from a three-joint on a column foundation, only a lower column of the extraction column is cut off, an upper column of the extraction column and connection of the upper column are not influenced, and an original crane beam, an original column top joist, a roof truss beam, a roof system and the like above are not changed. Compared with the prior art, the roof system does not need to be dismantled, the workload is small, and the construction period is shortened. And indoor operation is not influenced by weather. The crane beam and the original structure do not need to be replaced, and manufacturing cost is reduced. The newly-added joists, the newly-added latticed columns, the reinforcing rib plates, the connecting cross beams and other newly-added structures can be prefabricated in a factory and do not need to be manufactured on site, the factory installation and construction time is greatly shortened, and the influence on production is reduced to the minimum.
本发明公开一种钢结构厂房抽柱加固施工方法，采用新增托梁，将抽柱从柱基础上立根改为立根于新增托梁上，仅对抽柱下柱进行切除，不影响抽柱上柱及其连接，上方原吊车梁、原柱顶托梁、屋架梁及屋面系统等均未改变。与现有技术相比，本发明无需拆除屋面系统，工作量较小，工期缩短。室内作业，不受天气影响。无需更换吊车梁及以上原结构，降低造价。新增托梁、新增格构柱、加固劲板、连接横梁等新增结构均可在工厂预制，不需要现场制作，极大地缩短了工厂安装施工时间，对生产的影响降低到最小。
