Cylindrical shear brace connecting structure for precast pier and precast plate

Abstract

The invention relates to a cylindrical shear brace connecting structure for a precast pier and a precast plate. According to the connecting structure, the precast concrete beam plate and the precast concrete pier are connected through a cylindrical shear brace and connecting bolts; the lower end of the cylindrical shear brace is arranged in a pier top cavity and is composed of a backing board, a porous cylinder and a flange plate in a welding mode; the backing board and the flange plate are arranged in parallel; the porous cylinder is welded between the backing board and the flange plate; theflange plate is arranged parallel to the precast concrete beam plate; the connecting bolts penetrate through bolt holes; the upper ends of the connecting bolts are anchored to the top of the precast concrete beam plate, and the lower ends of the connecting bolts are anchored to the flange plate; and after the bolt holes and the periphery of the cylindrical shear brace are plugged, concrete is poured, so that the precast pier and the precast plate can be quickly connected. Compared with the prior art, the connecting structure has the advantages that connecting construction is simplified, the on-site workload is greatly reduced, quick construction site connection of precast concrete members of a factory is realized, and the development of a highway industrial construction technology is promoted.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a connection structure of prefabricated piers and plate-tube shear braces. Background technique [0002] At present, adopting a structural point of view and an industrialized model to implement the construction of less soil, no soil, high efficiency, and low-cost projects at the level of scale and serialization is becoming the development direction of my country's green road construction. Among them, the complete set of technology for small and medium-sized structures is a key part of the implementation of green road construction and road industrialization. After years of exploration, although this technology has been greatly developed and the demonstration effect is good, there are still many shortcomings: such as insufficient large-scale construction, absence of key structures, lagging control structures, and lack of theoretical breakthroughs.

After years of exploration, although this technology has been greatly developed and the demonstration effect is good, there are still many shortcomings: such as insufficient large-scale construction, absence of key structures, lagging control structure and lack of theoretical breakthroughs

[0003] The fast and efficient connection between precast concrete components has always been a difficult problem in domestic design and construction, especially for precast concrete components of different shapes: using traditional cast-in-place connection methods, there are many temporary facilities, and the workload is too large; using traditional dry joints or glue Connection methods such as joints need to be used in conjunction with various connectors, and prefabrication and installation deviations of precast concrete components often make the alignment of connectors very difficult, making prefabrication and construction difficult, reducing the advantages of industrial construction, and difficult to connect. ensure
