Suspended cylindrical shear brace connection structure for precast pier and precast plate

Abstract

The invention relates to a suspended cylindrical shear brace connection structure for a precast pier and a precast plate. A precast concrete beam plate and a precast concrete pier are connected through a cylindrical shear brace and connecting bolts, a partition is arranged in a pier top cavity, the lower end of the cylindrical shear brace is suspended above the partition in the pier top cavity, the cylindrical shear brace is composed of a bottom brace plate, a pored cylinder and a flange plate through welding, the bottom brace plate and the flange plate are parallel, the pored cylinder is welded between the bottom brace plate and the flange plate, the flange plate is arranged parallel to the precast concrete beam plate, the connecting bolts penetrate bolt holes, the upper ends of the connecting bolts are anchored on the top of the precast concrete beam plate, the lower ends of the connecting bolts are anchored on the flange plate, concrete is cast in the bolt holes in place, concrete is cast above the partition in the pier top cavity in place, and thus the precast pier and the precast plate are quickly connected. Compared with the prior art, the connection structure is simplified,the on-site workload is greatly reduced, the quick connection of the factory precast concrete members is realized, and the development of highway industrialization construction technologies is promoted.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a prefabricated pier and plate suspension type tubular shear brace connection structure. 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...

[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
