Fabricated shear wall horizontal connection structure and construction method

Abstract

The invention relates to the technical field of building engineering, in particular to a fabricated shear wall horizontal connection structure and a construction method. The fabricated shear wall horizontal connection structure comprises a horizontal plate, two first connection plates in opposite arrangement are arranged on the upper portion of the horizontal plate, a plurality of bolt holes are formed in each first connection plate, two second connection plates in opposite arrangement are arranged on the lower portion of the horizontal plate, a plurality of second bolt holes are formed in each second connection plate, and a bolt is connected in each of the first bolt holes and the second bolt holes; an upper shear wall is arranged between the first connection plates, third bolt holes corresponding to the first bolt holes are formed in the upper shear wall, a lower shear wall opposite to the upper shear wall is arranged between the second connection plates, and fourth bolt holes corresponding to the second bolt holes are formed in the lower shear wall. The fabricated shear wall horizontal connection structure has the advantages that the shear walls are connected together quickly and firmly through a connector and a horizontal plate, so that construction efficiency is ensured, and integral performance and anti-seismic performance of a building are enhanced; high-strength bolts are utilized for connection, so that horizontal connection reliability of the shear walls is further improved.

Description

Technical field [0001] The invention relates to the technical field of construction engineering, in particular to a horizontal connection structure of an assembled shear wall and a construction method. Background technique [0002] The fabricated shear wall is prefabricated and maintained in the factory before being transported to the construction site for installation and connection. The quality of the connection will affect the seismic performance, integrity and stability of the overall structure. There are mainly horizontal joints and vertical direct joints in the structure of prefabricated shear walls. In the prior art, the horizontal joints are mainly connected in two ways: one is to set embedded parts in the concrete components, and use them during assembly. Welding connection; the second is to set shear teeth at the connection of the shear wall, pre-connect by welding, and then grouting into the shear teeth of the two prefabricated shear walls. The first method is fast an...

Problems solved by technology

The first method is fast and efficient, but the overall structural stability is poor, and the anti-seismic effect is not satisfactory. The second method is adopted. Although the anti-seismic performance of the overall structure is improved, the construction is more difficult, and maintenance time is required after grouting, resulting in a longer construction period.
