Reinforcing structure of light steel structure roof purline and construction method
The invention relates to a reinforcing structure and a construction method of a light steel structure roof purline, and the reinforcing structure comprises an original roof purline which is a C-shaped steel purline; the purline reinforcing plate is arranged at the bottom of the midspan of the C-shaped steel purline and is fixedly connected with the web of the C-shaped steel purline; the tensioning anchorage devices are symmetrically installed at the two ends of the lower flange of the C-shaped steel purline, and penetrating holes are reserved in the tensioning anchorage devices in the length direction of the C-shaped steel purline; the tensioning clamps are symmetrically arranged on the side, away from the end of the C-shaped steel purline, of the tensioning anchorage device, tensioning screws are arranged on the tensioning clamps, one ends of the tensioning screws are fixedly connected to the tensioning clamps, and the other ends of the tensioning screws are suitable for penetrating through the penetrating holes and are fixed through nuts; and the prestress tensioning strip is arranged on the lower surface of the purline reinforcing plate, the two ends of the prestress tensioning strip are clamped and fixed to the tensioning clamp, and prestress can be applied to the purline reinforcing plate and the original roof purline when the prestress tensioning strip is tensioned. The bearing capacity and deformation requirements of the original roof purline after the load is increased can be met without dismantling the original structure, and the safety of the structure is guaranteed.
本发明涉及一种轻钢结构屋面檩条的加固构造、施工方法，该加固构造包括原屋面檩条，为C型钢檩条；檩条加固板，设置在C型钢檩条跨中的底部，并且与C型钢檩条腹板固定连接；张拉锚具，对称安装在C型钢檩条下翼缘的两端部，张拉锚具上沿C型钢檩条的长度方向预留有穿设孔；张拉夹具，对称设置在张拉锚具远离C型钢檩条端部一侧，张拉夹具上设有张拉螺杆，张拉螺杆一端连接固定于张拉夹具，另一端适于穿过穿设孔并由螺母固定；预应力张拉条，布设于檩条加固板的下表面，其两端被夹持固定于张拉夹具，能够在被张拉时对檩条加固板及原屋面檩条施加预应力。本发明无需拆除原有结构即可满足增加荷载后原屋面檩条的承载能力和变形要求，保证结构的安全性。
