Prefabricated pier and plate cross-shaped shear bracing connecting structure

Abstract

The invention relates to a prefabricated pier and plate cross-shaped shear bracing connecting structure. A prefabricated concrete beam plate and a prefabricated concrete pier are connected through a cross-shaped shear bracing and connecting bolts. The lower end of the cross-shaped shear bracing is arranged in a pier top cavity, and the cross-shaped shear bracing is constituted by welding of a bottom supporting plate, perforated plates and a flange plate. The bottom supporting plate and the flange plate are arranged parallelly, the perforated plates are welded between the bottom supporting plate and the flange plate in a cross-shaped mode, and the flange plate is arranged to be parallel to the prefabricated concrete beam plate. The connecting bolts penetrate through bolt holes, the upper ends of the bolts are anchored at the top of the prefabricated concrete beam plate, and the lower ends of the bolts are fixed to the flange plate. After the bolt holes and the periphery of the cross-shaped shear bracing are blocked, concrete is poured, and prefabricated pier and plate quick connecting is achieved. Compared with the prior art, the connecting structure is simplified, the on-site workamount is reduced greatly, quick connecting of factory prefabricated concrete components is achieved on a construction site, and development of a highway industrialization building technology 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 slab cross 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
