Conveniently-assembled steel box girder for curved landscape bridge and hoisting construction process of conveniently-assembled steel box girder

Abstract

The invention discloses a conveniently-assembled steel box girder for a curved landscape bridge and a hoisting construction process of the conveniently-assembled steel box girder, and relates to the technical field of box girder hoisting. In each steel box girder, a bottom plate and a top plate are oppositely arranged, and first webs are located on the two sides of the bottom plate in the length direction; second webs are located at two ends of the bottom plate in the length direction, and the first webs and the second webs are fixedly connected with the bottom plate and the top plate respectively; a plurality of limiting grooves are formed in the opposite wall surfaces of the bottom plate and the top plate, and the two ends of the supporting block are embedded into the limiting grooves correspondingly; a plurality of connecting pipes are connected to the peripheral wall of a grouting pipe and inserted into the side wall of a supporting block; a containing cavity is formed in the supporting block, the grouting pipe, the connecting pipes and the containing cavity are communicated, and one end of each connecting pipe is blocked. According to the invention, the problem of low construction efficiency of direct on-site construction is solved, and the steel box girder has the effects that constructors can conveniently and quickly pre-assemble the steel members into the steel box girder in the prefabrication field, the aerial work time can be shortened, and the overall construction efficiency of the bridge body is improved.

Description

technical field [0001] The invention relates to the technical field of box girder hoisting, in particular to an easy-to-assemble steel box girder for a curved landscape bridge and a hoisting construction process thereof. Background technique [0002] At present, in order to pursue the coexistence of beauty and practicality, there are more and more water conservancy facilities combining function and form. Landscape bridges often appear in water conservancy projects at the junction of embankments and cities. The artistry and aesthetics of a bridge mainly depend on its superstructure expression. As an architectural artwork, the landscape bridge is different from ordinary bridges in plane curve and bridge section, with different shapes and unique styles. [0003] Most of the existing curvilinear landscape bridges in water conservancy projects adopt the method of on-site construction and construction. First, according to the construction progress, the corresponding construction ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the method of direct construction on site is adopted, and the equipment and materials enter the site in batches, and the turnover time of materials and equipment is long, which easily leads to a long period of installation and construction of the steel box girder; and the box girder In the process of beam hoisting, there are many high-altitude operations, and the total time of high-altitude operations is relatively long by adopting the method of hoisting while construction is being carried out on site.

In summary, the existing landscape bridge hoisting and high-altitude operations take a long time, and the equipment and material turnover time is relatively long, which easily affects the construction efficiency of steel box girder hoisting and construction, and also leads to a longer overall construction time
