Corrosion-resistant concrete guardrail permanent formwork and construction method
The invention belongs to the technical field of bridges, and relates to a corrosion-resistant concrete guardrail permanent formwork and a construction method.The first formwork, the second formwork, the third formwork and the fourth formwork are installed on a guardrail reinforcement cage through positioning bolt assemblies, and the second formwork is in lap joint with the upper portion of the first formwork and installed on the collision face of a guardrail; the third formwork is lapped above the fourth formwork and mounted on the back face of the guardrail, the formworks can be conveniently adjusted for fine adjustment and positioning in an inner and outer bolt adjusting mode, and the thickness of a concrete protection layer poured inside and outside the guardrail is strictly guaranteed; the template can be used for guardrail pouring construction, and can be conveniently popularized to concrete member pouring construction scenes in other durable environments by adopting different template types.
本发明属于桥梁技术领域，涉及一种耐腐蚀混凝土护栏永久模板及施工方法，第一模板、第二模板、第三模板和第四模板通过定位螺栓组件安装在护栏钢筋笼上，第二模板搭接在第一模板上方且安装在护栏迎撞面，第三模板搭接在第四模板上方且安装在护栏背面，通过内外螺栓调节的方式，可方便调整模板进行微调定位，严格保证护栏内外面浇筑混凝土保护层厚度；不仅可以用于护栏浇筑施工，通过采用不同的模板型式，还可以方便的推广到其他耐久性环境的混凝土构件浇筑施工场景中。
