L-shaped prefabricated composite shear wall vertical anti-seismic connection node and construction method thereof

Abstract

The invention belongs to the technical field of building structures and particularly relates to an L-shaped prefabricated composite shear wall vertical anti-seismic connection node and a construction method thereof. The L-shaped prefabricated composite shear wall vertical anti-seismic connection node comprises a composite slab type shear wall which is formed by a first prefabricated composite slab type shear wall and a second prefabricated composite slab type shear wall which are connected with each other; a first type reinforcement stirrup cage and first steel dowels are arranged in the first prefabricated composite slab type shear wall; a second type reinforcement stirrup cage and second steel dowels are arranged in the second prefabricated composite slab type shear wall; the first type reinforcement stirrup cage and the second type reinforcement stirrup cage are connected with each other; concrete is cast in situ at the positions of the first type reinforcement stirrup cage, the second type reinforcement stirrup cage, the first steel dowels, the second steel dowels and a non-prefabricated layer of the composite slab type shear wall. According to the L-shaped prefabricated composite shear wall vertical anti-seismic connection node and the construction method thereof, the shear walls can be connected into a whole at the position of the wall corner, the resistance to the seismic force is large, and the like.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to an L-shaped prefabricated laminated shear wall vertical anti-seismic connection node and a construction method thereof. Background technique [0002] Shear walls are the partition walls and enclosure walls of buildings, generally made of reinforced concrete. This kind of wall not only bears the vertical load transmitted by horizontal members, but also bears the horizontal load transmitted by wind force or earthquake. In the seismic code, the shear wall is also called the seismic wall. The shear wall structure system has good bearing capacity, and has good integrity and space, and has better lateral force resistance than the frame structure, and is suitable for building buildings with a height of 50-120 meters. At the connection between the shear wall and the shear wall, reliable joints are needed to connect the shear wall and the shear wall as a whole. Un...

Problems solved by technology

This utility model is easy to construct, and the amount of reinforcement is less, but there are only "∩" type insert bars and cast-in-place concrete with a square thickness of the shear wall at the joint between the shear wall and the shear wall. The capacity of vertical and horizontal loads is limited, and the safety performance of the structure is not high
