Arch camber reinforcing device suitable for large-span steel structure cantilever beam and construction method of arch camber reinforcing device
In order to solve the problem that an existing large-span steel structure cantilever beam is poor in reinforcing effect, the arching reinforcing device suitable for the large-span steel structure cantilever beam comprises an external prestress anchoring structure, a pair of steel strand fixing structures and a steel strand. One end of the steel strand is fixedly arranged on the steel strand fixing structure on one side of the external prestressing anchoring structure, and the other end of the steel strand penetrates through a lifting hole formed in one end of the cantilever beam and then is fixedly arranged on the steel strand fixing structure on the other side of the external prestressing anchoring structure. The overall design is reasonable, the structure is simple, construction is convenient, and the arching reinforcing device solves the quality problems of installation, impression and the like caused by too large sinking deflection of a large-span steel structure cantilever beam.
为了解决现有大跨度钢结构悬臂梁的加固效果差的问题，本发明提供一种适用于大跨度钢结构悬臂梁的起拱加固装置，包括体外预应力锚固结构、一对钢绞线固定结构和钢绞线，所述钢绞线的一端固定设置在体外预应力锚固结构一侧的钢绞线固定结构上，其另一端穿过设置在悬臂梁一端处的吊孔后固定设置在体外预应力锚固结构另一侧的钢绞线固定结构上。本发明整体设计合理、结构简单、施工方便，采用该起拱加固装置解决了大跨度钢结构悬臂梁因下沉挠度过大引起安装及观感等质量问题。
