Special formwork for bridge integrated cast-in-situ anti-collision barrier and hanging plate and construction method thereof

Disclosed are a special formwork for a bridge integrated cast-in-situ anti-collision barrier and hanging plate and a construction method thereof. The formwork comprises an internal formwork, an external formwork and a base formwork; the internal formwork is fixed on a bridge edge plate through a supporting system; the external formwork which is hung on the external side is connected with the internal formwork through split bolts; one end of the base formwork is connected with the bottom of the external formwork and the other end is provided with a height adjustable vertical plate to be abut against the bottom surface of a bridge; the base formwork and arrangement achieved barrier internal reinforcement bars are fixedly welded through T-shaped hooks. A construction process comprises assembly, hoisting, fixation and connection of the formworks, height adjustment of the vertical plate, formwork integral quality testing and the like. According to the special formwork for the bridge integrated cast-in-situ anti-collision barrier and hanging plate, a detailed design is performed on the prior art, flexible adjustment of the formwork is achieved through the height adjustment vertical plate, support-free fixation of the bottom of the formwork is achieved through the T-shaped hooks, and accordingly preconditions are provided for integral effect formation of the anti-collision barrier and the hanging plate, the safety, the reasonability and the economic efficiency of the formwork are guaranteed, and the engineering construction quality and safety is effectively guaranteed.
