Embodiment 1

[0032] Example 1, such as Figure 1 to Figure 4 As shown, the vertical multi-hinge connection structure between the prefabricated shear walls of the present invention includes the first prefabricated shear wall 1, the second prefabricated shear wall 2 and the embedded connector 3;

[0033] The first prefabricated shear wall 1 and the second prefabricated shear wall 2 are arranged vertically, and the first prefabricated shear wall 1 is connected to the second prefabricated shear wall 2 through at least two embedded connectors 3;

[0034] The gap between the first prefabricated shear wall 1 and the second prefabricated shear wall 2 is filled with grouting material 7 .

[0035] Further: the pre-embedded connector 3 includes two lug assemblies 4 and bearing rods 5, one of which is pre-embedded on the bottom end surface of the first prefabricated shear wall 1, and the other lug assembly 4 is pre-embedded On the top end surface of the second prefabricated shear wall 2; the two lug ...

Embodiment 2

[0039] Embodiment 2, the construction method of the vertical multi-hinge connection structure between the prefabricated shear walls, comprises the following steps:

[0040] Step 1: Prefabrication of the shear wall; place the prefabricated two ear plate assemblies 4 on the same side of the shear wall formwork 6, and fix them with the steel bars inside the shear wall by spot welding; Concrete is poured in the center to complete the production of the shear wall;

[0041] Step 2: Preliminary connection of the first prefabricated shear wall 1 and the second prefabricated shear wall 2; at the construction site, first hoist the second prefabricated shear wall 2 in place, and then hoist the first prefabricated shear wall 1 to The top of the second prefabricated shear wall 2, and make the bearing hole 404 position on the upper and lower lug assembly 4 correspond, then insert the bearing rod 5 in the bearing hole 404, complete the first prefabricated shear wall 1 and the second Prefabr...

Abstract

The invention relates to a vertical multi-hinge connection structure between assembled shear walls and a construction method, belongs to the technical field of assembled concrete structures, and in order to solves the problems that alignment connection of steel bars is needed in vertical connection construction of the existing assembled shear walls, the processing and mounting accuracy and the technical requirements for workers are high, and the strength is difficult to reach the standard. The left and right ends of the bottom end surface of a first pre-cast shear wall are connected with the top end surface of a second pre-cast shear wall through pre-buried connecting pieces; two pre-buried connecting pieces are defined as a first pre-buried connecting piece and a second pre-buried connecting piece; each pre-buried connecting piece comprises two lug plate components and a bearing rod; and the two lug plate components of the first pre-buried connecting piece are respectively pre-buriedat the left ends of the lower end surface of the first pre-cast shear wall and the upper end surface of the second pre-cast shear wall. The vertical multi-hinge connection structure between the assembled shear walls and the construction method have the advantages of simple connection construction process, high construction speed, reliable force transfer and high strength.

Description

technical field [0001] The invention relates to a vertical connection structure of a shear wall, in particular to a vertical multi-hinge connection structure and a construction method between prefabricated shear walls, and belongs to the technical field of prefabricated concrete structures. Background technique [0002] The prefabricated structure has the advantages of high production efficiency, energy saving, green environmental protection, easy to ensure the quality of construction projects, etc., and has become one of the important development directions of future buildings. The vertical connection technology of prefabricated shear wall structures is one of the important issues in the development of prefabricated concrete structures. The connection between prefabricated shear wall components must effectively connect individual structural components to each other into a unified whole, so that the entire building structure is coordinated and the internal force can be trans...
