Reinforcing structure and method for lifting large-span multi-truss truss
The invention discloses a reinforcing structure and method for lifting a large-span multi-truss truss. The structure and the method are applied to the large-span multi-truss truss. The reinforcing structure comprises a plurality of reinforcing units, the reinforcing units are distributed in the length direction of the large-span multi-truss truss in a spacing manner, each reinforcing unit comprises an outer frame, each outer frame comprises a plurality of outer frame rods, the outer frame rods are used for connecting two adjacent chord rods, and in each reinforcing unit, the outer frame rods are connected end to end, or the outer frame rods are connected with web rods end to end, so that the outer frame is closed. According to the reinforcing structure for lifting the large-span multi-truss truss, the reinforcing structure for lifting the large-span multi-truss truss is mounted in the large-span multi-truss truss, all the outer frame rods can support a single-truss truss, loads generated during lifting are dispersed to the chord rods or the web rods of the single-truss truss from the lifting points, stress concentration at the lifting points can be prevented, and deformation at the lifting points is reduced.
本发明公开了一种大跨度多榀桁架提升用加固结构及加固方法，应用于大跨度多榀桁架，其中加固结构包括加固单元，设置有多个并沿大跨度多榀桁架的长度方向间隔分布，加固单元包括外框，外框包括若干外框杆，外框杆用于连接两个相邻的弦杆，每一加固单元内，多个外框杆首尾相接，或多个外框杆与腹杆首尾相接，以使外框闭合。在大跨度多榀桁架的内部安装大跨度多榀桁架提升用加固结构，各外框杆能够对单榀桁架进行支撑，将提升时的荷载由提升吊点处分散至单榀桁架的弦杆或腹杆上，能够防止提升吊点处出现应力集中，减少提升吊点处的变形。
