Abstract

The invention belongs to the technical field of bridge construction, and particularly relates to a cast-in-place box girder bailey support which comprises an upper chord and a lower chord, two vertical rods are symmetrically arranged between the upper chord and the lower chord, and the two ends of the upper chord and the two ends of the lower chord are each provided with a female head and a male head which are used for butt joint. Fixing blocks are fixedly welded to the sides, close to each other, of the two vertical rods, the same supporting rod is fixedly connected between the upper chord and the lower chord, and the supporting rod is located between the two vertical rods; the invention further discloses a construction method. According to the invention, through mutual connection among the upper chord members, the lower chord members, the vertical rods, the supporting rods and the inclined supporting rods, the connection mode is simple and easy to operate, the connection stability is high, a mutually restricted and mutually supported supporting net rack is constructed after connection, the connection nodes are not easy to break and deform, the supporting strength is greatly improved, and the supporting effect is good. And meanwhile, disassembly and transportation are facilitated, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a Bailey bracket of a cast-in-situ box girder and a construction method thereof. Background technique [0002] Bailey frame is also known as "fabricated highway steel bridge", formerly known as "321" highway steel bridge. It is my country's combat readiness highway steel bridge. The Bailey frame is a steel frame formed into a certain unit, which can be spliced ​​and assembled into many components and equipment. Bailey Bridge is the most widely used and most popular bridge in the world. It has the characteristics of simple structure, convenient transportation, fast erection and easy decomposition. At the same time, it has the advantages of large bearing capacity, strong structural rigidity and long fatigue life. It can form temporary bridges, emergency bridges and fixed bridges of various types and purposes according to the different spans of actual needs, and has t...
