Background technique

With the development of modern industrial technology, prefabricated buildings have begun to attract people's interest. Prefabricated buildings have the advantages of short construction period, low energy consumption, green environmental protection, etc., and prefabricated buildings can carry out standardized production and industrialized construction, which can save materials. It is very convenient and fast to reduce waste and improve the quality of buildings. Prefabricated buildings have become the development trend of the construction industry. Part or all of the components of the building are prefabricated in the factory, then transported to the construction site, and the building is assembled by reliable connection, which is called a prefabricated building.

In the current prefabricated buildings, steel plate shear walls are often involved. Steel plate shear walls have good mechanical properties and seismic performance, and play a pivotal role in prefabricated buildings. Steel plate shear walls and reinforced shear walls Similarly, there are two types of joint connection forms: one is the horizontal joint connection connecting the upper and lower steel plate shear walls; the other is the vertical joint connection connecting two adjacent walls on the same floor.

The mechanical performance of the assembled steel plate shear wall mainly depends on the quality of the connection joints of the two prefabricated steel plate shear walls. The gusset plate with holes is welded on the steel plate of the shear wall, the upper and lower gusset plates are anchored by bolts, and then the formwork is placed at the joint and concrete is poured to complete the connection of the upper and lower steel plate shear walls. Although this connection method is relatively common, it has the following disadvantages: 1. During the installation of the gusset plate, the lifting equipment needs to hang the upper steel plate shear wall all the time, and the upper steel plate shear wall needs to use additional brackets and other devices to fix it initially, and then the relevant staff can start the construction to connect the upper and lower steel plate shear walls; 2. The position of the gusset plate is located below the shear wall, and the workers need to squat down to operate. The construction is difficult and the quality of the connection is not easy Control, and the staff squatting work is prone to physical fatigue, and squatting work for a long time will also cause physical damage to the staff; 3. After the gusset plate is installed, it is necessary to support the formwork and pour concrete on site. This method is a wet connection. There are many construction procedures, and the sanitation of the site cannot be guaranteed.
