Vertical connection structure for prefabricated hollow shear wall

Abstract

The invention discloses a vertical connection structure for a prefabricated hollow shear wall. The vertical connection structure comprises an upper-layer prefabricated hollow wall body with embedded columns, a lower-layer prefabricated hollow wall body with embedded columns and a middle floor slab, wherein the upper-layer prefabricated hollow wall body with the embedded columns, the lower-layer prefabricated hollow wall body with the embedded columns are oppositely connected up and down. The four faces of the prefabricated hollow wall bodies with the embedded columns connected through the connecting structure are free of ribs, so that standardized production and transportation are easy; the width of the prefabricated hollow wall bodies is easy to change, and good adaptability is achieved,so that the connecting structure has a great positive effect on promotion of building industrialization and residential industrialization; on the basis that the bearing capacity and the lateral stiffness of a common prefabricated concrete wall body are not reduced, the dead weight of the prefabricated hollow wall bodies is reduced, so that the earthquake action is reduced, and a great breakthroughis made in the performance-based earthquake-resistant design; and meanwhile, due to the light dead weight of the prefabricated hollow wall bodies, hoisting is easy in the construction process, and the construction cost is reduced.

Description

technical field [0001] The invention belongs to the field of building structures, in particular to a vertical connection structure of an assembled hollow shear wall. Background technique [0002] Shear wall structure buildings have the advantages of good integrity, high bearing capacity, no protruding interior columns and high lateral rigidity, so they are widely used in the construction field. The hollow shear wall structure system is based on the traditional shear wall system, and a series of vertical holes are opened inside the wall along the height direction of the wall. It has the advantages of small effect and has very broad application prospects in low-rise and multi-storey residential buildings. Traditional cast-in-place shear walls have a series of problems such as huge amount of wet work on site, large demand for labor force, and serious environmental pollution. Therefore, the country puts forward the development slogan of building industrialization and housing in...

AI Technical Summary

Problems solved by technology

[0003] The development of prefabricated buildings is mainly limited by the connection nodes with the core concept of being equivalent to cast-in-place, while the prefabricated hollow shear wall structure mainly bears horizontal loads, and the mechanical properties of its vertical connection nodes are particularly important; prefabricated shear walls The connection methods of vertically distributed reinforcement mainly include sleeve grouting connection and grouting anchor lap connection; sleeve grouting connection has the disadvantages of high alignment accuracy of components, difficult quality inspection and high price, and the cost of grouting anchor lap The quality of the hole should not be guaranteed and it is easy to form a weakened area of ​​stiffness
