Arched corrugated steel-concrete combined bridge deck slab and construction method thereof
The invention discloses an arched corrugated steel-concrete combined bridge deck slab and a construction method thereof, and mainly relates to the technical field of bridges. The arch-shaped combined bridge deck slab comprises a concrete top plate, transverse PBL stiffening ribs, an arch-shaped corrugated bottom steel plate and a cantilever end protection plate. The arched corrugated combined bridge deck is connected with the upper flanges of the main beams through PBL shear keys; transverse PBL stiffening ribs distributed at intervals are welded at wave trough positions of the arched corrugated bottom steel plate to improve transverse rigidity, and a row of studs with heads are transversely welded at wave crest positions to resist interface shearing force; l-shaped steel is arranged at the tops of the transverse stiffening ribs between adjacent plate spans to resist hogging moment; flat folding sections are arranged at arch feet of the arched corrugated bottom steel plates and are connected to the upper flanges of the main beams and the PBL shear keys; and the arched corrugated bottom steel plate is also used as a bottom template during concrete pouring. The reinforced concrete bridge deck slab is excellent in structural performance, attractive in appearance and convenient to construct, and can effectively solve the problems that an existing reinforced concrete bridge deck slab is tedious in formwork erecting and disassembling, and concrete is prone to cracking.
本发明公开了一种拱形波纹钢‑混凝土组合桥面板及其施工方法，主要涉及桥梁技术领域。拱形组合桥面板包括混凝土顶板、横向PBL加劲肋、拱形波纹底钢板和悬臂端防护板；拱形波纹组合桥面板通过PBL剪力键与主梁上翼缘连接；拱形波纹底钢板波谷位置焊接间隔布设的横向PBL加劲肋以提高横向刚度，波峰位置横向焊接一排带头栓钉抵抗界面剪力；相邻板跨间横向加劲肋顶部设置L型钢以抵抗负弯矩；拱形波纹底钢板在拱脚处设置平折段连接于主梁上翼缘和PBL剪力键；拱形波纹底钢板兼做混凝土浇筑时的底模板。本发明结构性能优越、造型美观、施工方便，能有效解决目前钢筋混凝土桥面板存在的支模拆模繁琐、混凝土易开裂等诸多问题。
