Embodiment 1

[0033] Such as Figure 1 to Figure 5 A self-resetting assembled shear wall structure connection device shown includes a prefabricated shear wall 1 and a foundation shear wall 2, and the prefabricated shear wall 1 is provided with a reinforcement cage and several longitudinal bars 6, and is characterized in that , the prefabricated shear wall 1 includes an end restraint area 3, a middle restraint area 4 and a distribution rib area 5, the middle restraint area 4 is located in the middle of the prefabricated shear wall 1, and the end restraint area 3 is located at At both ends of the wall of the prefabricated shear wall 1, the distribution rib area 5 is located between the end restraint area 3 and the middle restraint area 4; the lower end of the end restraint area 3 of the prefabricated shear wall 1 is sleeved with an end The longitudinal reinforcement connecting plate 7, the longitudinal reinforcement connecting plate 7 at the end is welded to the longitudinal reinforcement 6 a...

Embodiment 2

[0036]The rest are the same as in Embodiment 1, except that the long screw anchor backing plate 12 is provided with triangular grooves on both sides of the prefabricated shear wall 1, and the grooves are connected with the prefabricated shears below the grooves. The included angle of force wall 1 wall surface is 1°.

Embodiment 3

[0038] The rest are the same as in Embodiment 1, except that the long screw anchor backing plate 12 is provided with triangular grooves on both sides of the prefabricated shear wall 1, and the grooves are connected with the prefabricated shears below the grooves. The included angle of force wall 1 wall surface is 89 °.

[0039] The invention applies energy dissipation and shock absorption to the assembled structure. This connection method improves the energy dissipation capacity of the shear wall structure, and the shear wall has self-resetting ability under lateral load, which can reduce the anti-seismic requirements of the overall structure and improve the main structure. The anti-seismic performance of the structure; at the same time, it has the characteristics of easy industrial production, more efficient and faster, and avoids the inconvenience caused by on-site wet operations and energy consumption pollution.

Abstract

The invention provides a self-resetting fabricated shear wall structure connecting device. The connecting device comprises a prefabricated shear wall and a foundation shear wall, and the prefabricatedshear wall is internally provided with a steel reinforcement cage and a plurality of longitudinal bars. The connecting device is characterized in that the prefabricated shear wall comprises an end confined region, a middle confined region and a distributing reinforcement region, wherein the middle confined region is located in the middle of a wall body of the prefabricated shear wall, the end confined region is located at both ends of the wall body of the prefabricated shear wall, and the distributing reinforcement region is located between the end confined region and the middle confined region; the purpose is to apply energy-dissipation earthquake-reduction to the fabricated structure, according to the connecting mode, the energy dissipation capacity of the shear wall structure is improved, the shear wall has self-resetting capacity under lateral loads, the seismic demand of the whole structure can be reduced, and the seismic performance of the main structure is improved; and at thesame time, the connecting device has the characteristic of easy industrial production and is more efficient and quicker, and the problems of inconvenience and pollution of energy consumption caused byon-site wet working are avoided.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a self-resetting assembled shear wall structure connecting device. Background technique [0002] The prefabricated shear wall structure refers to the standardized production of various components of the structure, including prefabricated shear walls, prefabricated beams, prefabricated floors, etc., in the factory, and then the prefabricated components are connected by bolts, welds or post-cast concrete at the construction site. connected structure. The prefabricated shear wall structure has light weight, low rigidity and good ductility. The prefabricated components are industrially produced, and the manufacturing process can be more refined than ordinary cast-in-place components. It has the advantages of labor saving, fast construction progress, and is conducive to realizing building energy saving and facilitating industrial production. And mechanized construction ...
