Fabricated UHPC-LP steel-concrete composite beam bridge capable of being quickly disassembled and construction method of fabricated UHPC-LP steel-concrete composite beam bridge
The invention discloses an assembly type UHPC-LP steel-concrete composite beam bridge capable of being quickly disassembled and a construction method thereof. Prefabricated UHPC bridge deck slabs are longitudinally and transversely connected through transverse wet joints and cast-in-place common concrete bridge deck slabs respectively, and the prefabricated UHPC bridge deck slabs and LP steel main beams form a composite structure through high-strength bolt connecting pairs. The connecting mode of the steel beam and the bridge deck slab is innovated, and the bridge deck slab is rapidly disassembled and replaced; two high-performance materials of UHPC and LP steel are adopted in the steel-concrete composite structure at the same time, according to the effective working width of the structure, the material utilization efficiency is fully exerted, weld joints in steel beam manufacturing are reduced, lightweight and economical design of the height of the steel-concrete composite bridge is achieved, and meanwhile transportation and installation are convenient; the structure has the remarkable advantages that the bearing performance and durability are excellent, the economic performance is good, construction is convenient and fast, replacement is convenient, and the current sustainable development low-carbon construction concept is met.
本发明公开了一种可快速拆卸的装配式UHPC‑LP钢混组合梁桥及其施工方法，预制UHPC桥面板之间分别通过横向湿接缝和现浇普通混凝土桥面板进行纵向连接和横向连接，并通过高强螺栓连接副与LP钢主梁形成组合结构。本发明所创新了钢梁和桥面板连接方式，实现了桥面板快速拆卸和更换；本发明在钢混组合结构中同时采用UHPC和LP钢两种高性能材料，根据结构有效工作宽度，充分发挥材料利用效率，减少了钢梁制作中的焊缝，实现了钢混组合桥梁高度的轻量化和经济化设计，同时便于运输、安装；本发明结构具有承载性能和耐久性优异，经济性能良好，施工便捷，更换方便，符合当前可持续发展的低碳建造理念等显著优点。
