Modular hinged prefabricated assembled truss composite beam structure
The invention discloses a modular hinged prefabricated assembled truss composite beam structure which comprises a main truss rod. The number of the panel assemblies is multiple, and the multiple panel assemblies are arranged in the longitudinal bridge direction; a plurality of main truss rods are arranged below the panel assembly at intervals in the transverse bridge direction, and every two adjacent main truss rods are hinged in the longitudinal bridge direction. A plurality of joints are formed in the panel assembly, the plurality of joints divide the panel assembly into a first panel and a second panel, and at least two main truss rods are arranged below each of the first panel and the second panel; a longitudinal bridge direction support assembly; a transverse bridge direction supporting assembly; the adjacent first panels and second panels are connected through the wet joints, and the two adjacent first panels and the two adjacent second panels are connected through the wet joints. According to the invention, the problem of fatigue cracking of the concrete bridge deck at each connection part caused by over-strong constraint of the concrete bridge deck and the truss rod piece of the traditional truss composite beam bridge is avoided, meanwhile, the full-factor factory prefabrication and modular rapid assembly mode of the bridge structure is realized, and the construction speed is accelerated.
本发明公开了模数式铰接预制拼装桁架组合梁结构，包括，主桁杆；面板组件，面板组件设置有若干个，若干面板组件沿纵桥向设置；面板组件下方沿横桥向间隔设置有若干主桁杆，沿纵桥向相邻的两主桁杆铰接；面板组件上开设有若干接缝，若干接缝将面板组件分割成第一面板和第二面板，且第一面板和第二面板下方均至少设置有两主桁杆；纵桥向支撑组件；横桥向支撑组件；湿接缝，相邻第一面板和第二面板、相邻两第一面板以及相邻两第二面板之间均通过湿接缝连接。本发明避免了传统桁架组合梁桥混凝土桥面板与桁架杆件因其约束过强导致的连接处处混凝土桥面板的疲劳开裂问题，同时实现了桥梁结构全要素工厂化预制、模数式快速拼装模式，加快了施工速度。
