Description

technical field [0001] The invention relates to a connection structure between a prefabricated panel and a shear wall and a construction method. Background technique [0002] The use of prefabricated structures can save energy, water, and materials, greatly reduce construction waste, reduce noise pollution, reduce labor consumption and intensity, effectively improve the construction environment, and improve project quality, so it is favored by researchers and engineering designers. , is a structure worthy of promotion. In prefabricated structures, seam connection technology is the key technology, which is the key to ensure structural integrity and seismic performance.

[0003] The prefabricated shear wall structure has many engineering applications at present. The current connection between the shear wall and the floor is mainly through cast-in-place. Most of the floors are laminated slabs. Into the shear wall, post-cast concrete to form a whole. This method has a large amount of concrete pouring, low prefabrication rate, and still has a lot of on-site wet work. The site also needs to bind the steel bars of the cast-in-place part, which cannot give full play to the advantages of the prefabricated type.

[0004] The connection between the floor slab and the shear wall is the key part of the stress. The end of the existing laminated slab is stressed. If it is strengthened at the end during construction, it can only be realized by configuring more steel bars. If no reinforcement is added to the original In the case of

[0005] After the shear wall and the floor are integrated, the connection between the lower shear wall and the upper shear wall is currently mostly through sleeve grouting. The upper shear wall is placed on the floor, so it is necessary to wait for the floor to reach a certain strength before starting construction. The reinforcement sleeve of the upper shear wall is sleeved on the reinforcement extending from the lower shear wall, and connected by sealing strips and sleeve grouting. This method has a single form and has a great impact on the quality of on-site construction. It is not easy to control and the construction is troublesome; and the shear The connection of the force wall is not all the steel bars are connected, but only a single steel bar is connected at a certain distance except the edge members. This connection is not reliable enough, and the seismic performance and ductility are not ideal.

Some scholars have also proposed some connection methods for the upper and lower prefabricated shear walls, but most of them do not consider the installation of the floor slab, which is not practical
