Transverse adjustable beam bridge reinforcing structure and construction method
The transverse adjustable beam bridge reinforcing structure comprises two steel trusses which are longitudinally arranged, the two steel trusses are fixed to a bridge floor in a left-right mode and are in central symmetry relative to the bridge floor, the top of each steel truss is provided with a plurality of bases in the longitudinal direction, and the bases on the two steel trusses directly face each other in the left-right direction; a cross beam component capable of adjusting the transverse length is transversely connected to the two bases right facing each other in the left-right direction in a bridging mode, a transverse supporting component capable of adjusting the transverse length is connected to the lower portion of each cross beam component, and the transverse supporting components and the cross beam components define two triangular frameworks which are symmetrical in the left-right direction. The left outer side and the right outer side of each base on the two steel trusses are each provided with a bearing connecting component. A new bearing structure system is formed on the upper portion of the beam bridge, the load of an original beam bridge is shared, the mid-span bending moment and shear reaction of the beam bridge are effectively reduced, the beam bridge is reinforced and repaired, and the overall rigidity and bearing capacity of the beam bridge are improved.
本发明公开一种横向可调节的梁式桥加固结构及施工方法，包括纵向布置的两榀钢桁架，两榀钢桁架一左一右固定在桥面上且相对于桥面中心对称，每榀钢桁架的顶部沿纵向设有多个底座，两榀钢桁架上的底座左右正对，左右正对的两个底座上横向跨接一个能调节横向长度的横梁构件，每个横梁构件下方连接一个能调节横向长度的横向支撑构件，横向支撑构件与横梁构件围成一左一右对称的两个三角形架构，在两榀钢桁架上的每个底座的左外侧和右外侧都设置一个支承连接构件；在梁式桥的上部形成新的承载结构体系，分担了原有梁式桥的荷载，有效降低梁式桥的跨中弯矩和剪力反应，起到对梁式桥加固和修复的作用，增加梁式桥的整体刚度和承载能力。
