Description

Technical Field

[0001] The utility model relates to the technical field of displacement type dampers, in particular to a displacement type damper. Background Art

[0002] Reinforced concrete shear wall structures have high lateral stiffness and high bearing capacity, and are important structural components in high-rise structural systems. When designing and constructing buildings, the impact of factors such as earthquakes is taken into consideration, and a connecting beam damper is usually installed between the two connecting beams so that the deformation and energy consumption of the connecting beams during earthquakes are concentrated in the connecting beam damper, thereby protecting the wall limbs and the elastic ends of the connecting beams from serious damage.

[0003] For example, a Chinese patent (publication number: CN217811714U) discloses a displacement-amplifying viscoelastic connecting beam damper, comprising a left connecting plate, a right connecting plate and an even number of rotating connecting plates, wherein the rotating connecting plates are symmetrically arranged on both sides of the left connecting plate and the right connecting plate, and the two ends of the rotating connecting plates are respectively hinged to the left connecting plate and the right connecting plate, and viscoelastic energy-absorbing plates are bonded between the rotating connecting plates and the left connecting plates and the right connecting plates. The damper is provided with viscoelastic energy-absorbing plates between the ends of the left connecting plate and the rotating connecting plate and between the ends of the right connecting plate and the rotating connecting plate, and the rotating connecting plates drive the viscoelastic energy-absorbing plates to rotate and absorb energy, and the viscoelastic energy-absorbing plates provide damping force, so that the damper can dissipate a large amount of seismic energy under relatively small rotational deformation, and the displacement-amplifying mechanism of the rotating connecting plates can effectively improve the energy-absorbing effect.

[0004] However, the above search patent still has some shortcomings. When in use, the damper mainly relies on the friction damping between the viscoelastic energy dissipation plate and the left vertical plate and the right vertical plate to achieve the energy dissipation effect. During shock absorption, the viscoelastic energy dissipation plate and the left vertical plate and the right vertical plate will be consumed. The damper disclosed in the above search patent is not convenient for fast and efficient installation and disassembly, and is not convenient for replacement when the damper is seriously worn. It is inconvenient to use, so a displacement damper is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above-mentioned object, the utility model provides the following technical solution: a displacement damper, comprising a damper body, wherein the top surface and the bottom surface of the damper body are both equipped with mounting bins;
