Fabricated shear-wall vertical-joint tooth-space-type energy-consuming connecting device

Abstract

The invention provides a fabricated shear-wall vertical-joint tooth-space-type energy-consuming connecting device. The joint edge of a prefabricated shear wall piece is prefabricated to be a tooth-space-type edge, viscous-elastic materials are pre-pasted or site filled in a joint, and the prefabricated shear wall piece is pulled and tied in the horizontal direction by using pull rods on the two sides of the shear wall surface at the vertical joint to keep the integrality of the shear wall in the horizontal direction; anchor bearing plates are welded at the ends of the pull rods, vertical long round bolt holes are reserved in the anchor bearing plates, so that the pull rods only transmit the internal force in the horizontal direction but release the vertical shear force, and thus the energy dissipation capacity of the viscous-elastic materials can be more effectively developed. According to the fabricated shear-wall vertical-joint tooth-space-type energy-consuming connecting device, the performance of a traditional cast-in-place belt rigid connection is improved, the energy-dissipating capacity of the prefabricated concrete shear wall structure is enhanced, and wet construction of a construction site is cast off; and an energy-dissipation device and the prefabricated shear wall are combined, industrialized production is facilitated, and the fabricated shear-wall vertical-joint tooth-space-type energy-consuming connecting device can be widely applied to the prefabricated concrete shear wall structure.

Problems solved by technology

[0003] The connection of vertical joints between prefabricated shear walls is a key technology in the prefabricated concrete shear wall structure. At present, the commonly used vertical joint connection method is mainly cast-in-place concrete connection. The workload of wet work on site in this way Large, complex construction, difficult to guarantee quality, and not conducive to energy conservation and environmental protection, so prefabricated prefabricated shear wall structures need to propose a more efficient and quick vertical joint connection method

In general, the integrity and rigidity of the prefabricated shear wall structure is lower than that of the cast-in-place shear wall structure, and the seismic performance of the prefabricated shear wall structure is lower than that of the cast-in-place shear wall structure

Due to the poor performance of prefabricated shear wall structures in previous earthquakes, people lack confidence in the seismic performance of prefabricated shear wall structures, and the proportion of prefabricated shear wall structures in my country's construction industry is not very high
