Abstract

The invention relates to the field of buildings, in particular to an eddy-current damping wall and a building. The eddy-current damping wall comprise a first transmission shaft, at least one eddy current assembly and a transmission mechanism. The eddy current assembly comprises conductor plate back iron rotationally connected with the first transmission shaft, the outer side of the conductor plateback iron is sleeved with a conductor plate and permanent magnet back iron in sequence, at least two permanent magnets are arranged on the inner wall of the permanent magnet back iron, and the at least two permanent magnets are arranged in the circumferential direction of the permanent magnet back iron at intervals. The transmission mechanism is in driving connection with the first transmission shaft, and is used for converting linear motion into rotation of the first transmission shaft. According to the eddy-current damping wall, the eddy current assembly and the transmission mechanism are adopted as a main structure, an oil leakage phenomenon rarely happens or is avoided, the later maintenance charge is low, and the durability is good; and the eddy-current damping wall only generates damping, and therefore the eddy-current damping wall can also be suitable for the situation that the structural rigidity cannot be improved.

Description

technical field [0001] The invention relates to the building field, in particular to an eddy current damping wall and a building. Background technique [0002] Under the action of wind and earthquake loads, the building vibrates greatly, which seriously affects the safety and durability of the building. Measures should be taken to reduce the vibration (vibration) of the building. The damping wall is a passive energy-dissipating component, which uses the relative movement between the structural layers and is installed as a wall between the building layers to increase the damping of the structure to achieve energy dissipation and shock absorption. Compared with other energy dissipation and shock absorbing devices, the damping wall has the following advantages: [0003] (1) Easy to manufacture and install without complicated devices; [0004] (2) The wall area is larger and consumes more vibration energy; [0005] (3) Install the damping wall on the wall of the building with...
