Suspension bridge plate-truss combined beam mounting method
The invention relates to the technical field of bridge installation and especially relates to a suspension bridge plate-truss combined beam mounting method. In a installation and construction processof a suspension bridge plate-truss combined beam, a steel bridge deck plate and steel trusses are separately hoisted through hoisting equipment, the steel trusses are hoisted firstly, the adjacent steel trusses are hinged, the bridge deck plate is hoisted on the steel trusses, the steel trusses and the bridge deck plate are hoisted alternately in a hoisting process, and after the hoisted steel trusses are locally linear to form a bridge line, the adjacent steel trusses are rigidly connected. According to the method, the whole bridge girder is installed through separated hoisting of the steel trusses, single-time hoisting weight is reduced, rated hoisting weight of the hoisting equipment is decreased, meanwhile, construction is facilitated, construction efficiency is improved, constructionoperation surface division is clearer, welding operation is carried out on a bridge in a centralized mode when the plate truss is separated and hoisted, operation cross is small, and aloft work is little.
本发明涉及桥梁安装技术领域，具体涉及一种悬索桥板桁结合梁安装方法，通过在悬索桥板桁结合梁安装施工过程中，通过吊装设备将钢桥面板和钢桁架分离吊装，先吊装钢桁架，相临钢桁架之间铰接，将桥面板吊装在钢桁架上，吊装过程中钢桁架和桥面板交替进行吊装，当吊装的钢桁架局部线型成桥线型后，相临钢桁架之间进行刚接。通过上述方法进行钢桁架的分离吊装安装整个桥主梁，降低了单次吊装重量,减小了吊装设备的额定吊重，同时便于施工，提高了施工效率，施工作业面划分更清晰，板桁分离吊装时焊接作业集中在桥上进行，作业交叉小，高空作业少。
