Abstract

The invention proposes a high pier side-span cantilevered girder Bailey truss structure and its construction method, and relates to the technical field of cantilevered beam side-span construction, including a Bailey truss module, a positioning component, an anchoring component, a beam and a longitudinal beam, and a Bailey truss The bottom of the module is equipped with a positioning component. The Bailey frame module is used to be erected on the cover beam of the high pier. The positioning component is used to be clamped on both sides of the cover beam. The Bailey frame module is divided into front The cantilever and the rear cantilever, the Bailey frame module is used to connect with the cover beam, the anchor assembly is arranged at the end of the rear cantilever to anchor to the cap of the high pier, and the beams are arranged at intervals between the bottom of the front cantilever of the Bailey frame module , the longitudinal beams are arranged at intervals on the upper end surface of the beams, which solves the problems in the prior art that the side span cast-in-place section of the cantilevered beams adopts many bracket members, the erection site is large, the period is long, and the installation and disassembly process is inconvenient. The structure and the whole construction process of the invention are simple and easy to operate, quick to install and disassemble, high in work efficiency, and high in material recycling rate.

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...
