Quick connecting structure for prefabricated pier and slab

Abstract

The invention relates to a quick connecting structure for a prefabricated pier and a prefabricated slab. The quick connecting structure comprises a prefabricated concrete beam slab and a prefabricatedconcrete pier, wherein the bottom part of the prefabricated concrete beam slab is provided with an embedding and fixing groove; a vertical communicating hole is formed in the top part of the prefabricated concrete beam slab, and is communicated with the embedding and fixing groove; the prefabricated concrete pier is provided with a pier top cavity; anchoring steel bars are vertically arranged inthe pier top cavity; an anchoring steel bar skeleton is arranged around the anchoring steel bars; when the prefabricated concrete pier is spliced, the prefabricated concrete pier is embedded into theembedding and fixing groove, and the anchoring steel bars penetrate through the pier top cavity, the embedding and fixing groove, the communicating hole and the upper surface of the prefabricated concrete beam slab; after the embedding and fixing groove is blocked by concrete, the concrete is filled via the communicating hole, and the concrete fill the pier top cavity, the embedding and fixing groove and the communicating hole, so as to form the quick connecting structure for the prefabricated pier and the slab. The quick connecting structure has the advantages that the connecting structure issimplified, the usage amount of material is reduced, the workload at site is greatly reduced, and the development of industrialized construction technique of highways 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 quick 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 rapid and effi...

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 rapid 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 wet joint connection methods, there are many temporary facilities, and the workload is too large; using traditional notches, teeth Blocks and other connection methods, the structure is complex, the steel bars are more damaged, prefabrication and construction are difficult, the advantages of industrialization are reduced, and the connection effect is difficult to guarantee
