Description
Technical Field
The invention belongs to the technical field of energy consumption vibration reduction of assembled building structures, and particularly relates to a prefabricated wall energy consumption connecting device.
Background
In recent years, the assembled building is in the market due to the advantages of rapid construction, high industrialization degree, manpower and material resources saving and the like. In the traditional prefabricated wall body installation process, the two wall bodies are connected in the longitudinal direction by adopting filling sleeves, and the mechanical properties of the two wall bodies are not greatly different from those of the cast-in-situ wall bodies. However, the two walls are generally welded by embedded parts in the transverse direction, so that the connection rigidity is weak, and compared with the cast-in-situ wall, the assembled wall has poorer integrity. And a larger intersection joint is easy to generate at the transverse junction of the two walls, and the current common practice is to directly fill the wall joint simply and then seal the surface. However, the method is easy to form a cold-hot bridge, so that the heat insulation effect of the building is weakened, and the energy consumption and vibration reduction capability is insufficient, so that the wall is easy to crack under transverse vibration. Therefore, research and development of the wall connecting device with reasonable design and obvious energy consumption effect is beneficial to improving the safety, stability and shock resistance of the assembled building.

One end of the first fixing plate 4 is fixedly connected with the wall 9, the other end of the first fixing plate is fixedly connected with the I-shaped steel column 8, and the fixing plate 4 is not long and is a sectional plate;
One end of the second fixing plate 5 is fixed on the wall 9, and the other end is opposite to the short side of the outer-covered steel plate 1; the second fixing plate 5 is connected with one short side of the groove plate 3 through the viscoelastic material 2 and fixedly connected with the wall 9 in a through length manner;

The prefabricated wall energy consumption connecting device is characterized in that two prefabricated walls with the energy consumption devices are required to be accurately butted and inserted.
The flange thickness of the I-shaped steel column 8 meets the depth requirement of the flange clamping groove.
