Bridge integrated cast-in-place anti-collision guardrail and special formwork for hanging board and its construction method

Abstract

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.

Description

technical field [0001] The invention relates to the construction field of urban bridge anti-collision guardrails, in particular to a special formwork used in the construction of bridge integrated cast-in-place anti-collision guardrails and hanging boards and a construction method thereof. Background technique [0002] Traditional anti-collision barriers include prefabricated hanging panels on the outside and cast-in-place parts on the inside. The production is complicated, the cost is high, there are many separate construction procedures, the construction speed is slow, and the colors of the external hanging panels and the anti-collision barriers are uneven. The design of pouring anti-collision guardrail and hanging board is novel and beautiful in appearance, which can better solve the problem of traditional split construction process, slow construction speed, uneven color of external hanging board and anti-collision guardrail, and pollution of external hanging board caused b...

Problems solved by technology

[0003] The purpose of the present invention is to provide a bridge integrated cast-in-place anti-collision guardrail and a special formwork for hanging panels, which solves the problem that the size of the existing integrated formwork is fixed, and the vertical length of the inner side of the hanging plate needs to be determined based on the thickness of the bridge wing plate. The thickness of the wing plate is uneven, the line shape of the bottom is not smooth, or the height of the bottom surface is different due to installation errors. The load-bearing of the formwork is relatively large, but the existing technology lacks special fixing components, and the size of the inner side of the hanging board formwork is limited. If it exceeds the limit, it will easily cause damage to the bottom formwork and cause poor safety of the formwork; at the same time, it also solves the problem of existing formwork The problem of poor stability and short service life; in addition, the present invention proposes a standardized construction method for this kind of bridge construction template, which solves the problems of lack of standardization, poor applicability, and inability to guarantee construction quality in the existing anti-collision guardrail construction operation
