Construction platform for span closure of continuous rigid frame bridge

Abstract

The invention discloses a construction platform for span closure of a continuous rigid frame bridge, and relates to the technical field of bridge engineering. The construction platform for the span closure of the continuous rigid frame bridge comprises a bottom plate, wherein the bottom plate is fixedly connected with perforated angle steels through screws; the bottom plate is fixedly connected with side plates and baffles through the perforated angle steels; the top of the bottom plate is provided with finish rolling thread steels; and the number of the finish rolling thread steels is four, and the finish rolling thread steels are divided into two groups. According to the construction platform for the span closure of the continuous rigid frame bridge, through the cooperation of the bottomplate, the side plates, the baffles, the perforated angle steels and other components, the project quality of the span closure of the continuous rigid frame bridge can be well ensured, the safety ofoperators is enhanced, the overall lifting and descending of the operation platform are improved, the construction time is greatly saved, various steel plates forming the operation platform can be flexibly assembled and disassembled, can be repeatedly used, and have good economic benefits, and the influence of the overall linear shape and the attractiveness of the bridge caused by large construction error is avoided.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a construction platform for closing the midspan of a continuous rigid frame bridge. Background technique [0002] In the construction of high-grade highways and municipal roads, continuous rigid frame bridges are an important form of continuous girder bridges. Because their main girders and piers are consolidated and their overall seismic performance is good, they are widely used. When the multi-span continuous rigid frame bridge is constructed by the hanging basket method, the stress system before and after the bridge is closed changes. Therefore, the closing of the mid-span is the focus of construction control, which has an important impact on the overall alignment and aesthetics of the bridge. [0003] In the prior art, only mechanical operation and manual alignment are used for construction, and there is no corresponding construction platform to ensure the quality ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a construction platform for closing the mid-span of a continuous rigid frame bridge, which solves the problem that in the prior art, construction is carried out only by mechanical operation and manual alignment, and there is no corresponding construction platform to Ensure the quality and work efficiency of the construction, increase the cost and increase the difficulty of the construction, and at the same time, it is easy to affect the overall alignment and aesthetics of the bridge due to large construction errors
