High-pier side-span cantilever beam Bailey truss structure and construction method thereof

Abstract

The invention provides a high-pier side-span cantilever beam Bailey truss structure and a construction method thereof, and relates to the technical field of cantilever beam side span construction. Thebailey truss comprises bailey truss modules, positioning assemblies, anchoring assemblies, cross beams and longitudinal beams, and the positioning assemblies are mounted at the bottoms of the baileytruss modules; the bailey truss modules are used for being erected on the bent cap of a high pier; the positioning assemblies are used for being clamped to the two side edges of the bent cap; the bailey truss modules are divided into a front end cantilever and a rear end cantilever on the two sides of the bent cap; the bailey truss modules are used for being connected with the bent cap; and the anchoring assemblies are arranged at the tail end of the rear end cantilever and used for being anchored to the bearing platform of the high pier. The cross beams are arranged between the bottoms of thecantilevers at the front ends of the bailey truss modules at intervals, the longitudinal beams are arranged on the upper end faces of the cross beams at intervals. The problems that in the prior art,many support rod pieces are adopted for a cantilever beam side span cast-in-place section, the erecting land is large, the period is long, and the mounting and dismounting process is inconvenient aresolved. The structure and the whole construction process are simple and easy to operate, mounting and dismounting are rapid, the work efficiency is high, and the material recycling rate is high.

Description

technical field [0001] The invention belongs to the technical field of side-span construction of cantilevered beams, and specifically provides a Bailey truss structure of side-span cantilevered beams with high piers and a construction method thereof. Background technique [0002] At present, the cast-in-place section of the side span of the cantilevered beam often adopts the support system of bowl button full hall frame and straight inclined column steel pipe frame. The support system also requires more fasteners, the amount of material is large, the period of erecting the support is long, the requirements for the foundation are high, and the amount of settlement generated is large. When the bridge deck and road surface are inconvenient to block traffic, the above two supports cannot be directly erected on the bridge deck and road surface. [0003] Correspondingly, there is a need in the art for a Bailey truss structure with side-span cantilevered girders with high piers an...
