[0002] The building damping wall is a safety device installed on the building to reduce earthquake damage. It is widely used in civil buildings, industrial buildings and bridges.

[0003] However, the existing damping walls for buildings still have many defects. For example, the existing damping walls have poor sealing performance, silicone oil is easily contaminated and thus affects product performance, and conventional open damping walls cannot be tilted during hoisting, making assembly inconvenient.

[0007] Furthermore, the damping wall is formed by connecting two or more viscous dampers in parallel.

[0008] Furthermore, the viscous damper inside the damping wall is anti-corrosive by hot-spraying zinc and painting, and the outer shell is anti-corrosive by hot-dip galvanizing process.

[0016] In order to further illustrate the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and embodiments, but they should not be construed as limiting the protection scope of the present invention. Example

[0017] like Figure 1-Figure 2 As shown, the utility model is a high-performance sealed viscous damping wall, comprising: a steel frame 1, a gapless ball joint 2, a bushing 3, a piston rod 4, a piston 5, a cylinder 6, an extension pipe 7, an experimental connecting hole 8, a shell 9, an ear plate 10, and an embedded part 11.

[0018] On the inner side of the steel frame 1 on both sides of a high-performance sealed viscous damping wall, more than two groups of gapless ball joints 2 are symmetrically fixedly connected, and a viscous damper is installed between each group of gapless ball joints 2. The viscous damper is anti-corrosive using hot-spray zinc and paint. A high-performance sealed viscous damping wall is sealed with an outer shell 9, and the outer shell 9 is anti-corrosive using a hot-dip galvanizing process. An experimental connection hole 8 is left on the steel frame 1, which can be directly connected to the experimental table. After the experiment is completed, it can be directly removed and used for on-site installation of the project. The outer side of the steel frame 1 is connected to the ear plate 10, and the ear plate 10 is fixed to the wall through embedded parts 11. The damping wall is rotated and tilted according to the actual situation on site. Under the action of external loads such as earthquakes or wind loads, the building wall drives the steel frame 1 to reciprocate. Since the inner side of the steel frame 1 is connected to the gapless ball joint 2 and the viscous damping wall, the purpose of realizing linkage energy consumption is achieved.

[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
