Construction method of modified high-strength concrete corrugated top plate combined bridge deck slab
The invention relates to a construction method of a modified high-strength concrete corrugated top plate combined type bridge deck slab, which comprises the following process steps: S1, laying profiled steel sheets: after concrete curing of a bridge deck slab, web linings on two sides of a middle fulcrum and an end cross beam support at the current period is completed, firstly, respectively laying open profiled steel sheets between cantilevers and boxes of a steel box girder, and then laying the open profiled steel sheets between the cantilevers and the boxes of the steel box girder; mounting a plug plate at the end part of the opening type profiled steel sheet; s2, steel bars, anchor bearing plates and prestressed ducts are installed; s3, modified high-strength concrete is poured, and after the side formworks are installed, the modified high-strength concrete is poured; and S4, concrete curing is conducted, after concrete pouring is completed, steam at the temperature of 45-55 DEG C is introduced through a steam pipeline, curing is conducted for 6-12 h, and the air pressure is controlled to range from 1.0 Mpa to 1.2 Mpa. The corrugated top plate and the concrete structure layer are reliably connected, the possibility of fatigue cracking of the steel bridge deck slab is reduced, and the construction quality of the bridge deck slab is obviously improved.
本发明涉及一种改性高强混凝土波形顶板组合式桥面板的施工方法，包括有以下工艺步骤：S1，铺设压型钢板，当前期的桥面板、中支点两侧腹板内衬以及端横梁支撑处的混凝土养护完成后，先在钢箱梁的悬臂、箱间分别铺设开口型压型钢板，再将开口型压型钢板的端部安装堵头板；S2，安装钢筋、锚垫板和预应力孔道；S3，浇筑改性高强混凝土，侧模板安装完成后浇筑改性高强混凝土；S4，养护混凝土，混凝土浇筑完成后，通过蒸汽管道通入45～55℃的蒸汽进行养护6～12h，气压控制在1.0～1.2Mpa。本发明的波形顶板和混凝土结构层之间联结可靠，降低了钢桥面板疲劳开裂可能性，明显改善桥面板的施工质量。
