[0002] A damper, also known as an energy dissipator or shock absorber, is a device that provides resistance to movement and dissipates kinetic energy. From the energy point of view, the energy input into the structure by earthquake is composed of the system's kinetic energy, deformation energy and damping energy, while the system's strain energy is composed of three parts: elastic deformation energy, plastic deformation energy and hysteresis energy. Energy dissipation and shock absorption technology is to dissipate the energy of earthquake input in a concentrated manner by increasing the damping of the structure, thereby avoiding and reducing damage to the main structure and achieving the purpose of shock absorption.

[0027] Please refer to Figures 1 to 4 , the embodiments provided by the utility model are:

[0028] A seismic energy dissipation damper for a building comprises a supporting base plate 1, a supporting top plate 2, a central damping component 3, a cross damping component 4 and a structural axis 5, wherein the supporting base plate 1 and the supporting top plate 2 are symmetrically arranged up and down, the central damping component 3 comprises a vertically arranged damping assembly 31, the damping assembly 31 comprises two seismic dampers 311 and a middle connecting member coaxially connecting the two seismic dampers 311, the cross damping component 4 comprises two damping assemblies 31 arranged in an X-shaped cross-symmetrical manner, the cross damping components 4 are two and are symmetrically arranged on the front and rear sides of the central damping component 3, the structural axis 5 coaxially hinges the cross damping component 4 and all the middle connecting members of the central damping component 3, the upper end of the damping assembly 31 is hinged to the supporting top plate 2, and the lower end is hinged to the supporting base plate 1.

[0030] Furthermore, an upper positioning hole 221 is provided on the middle top plate 22, and a lower positioning hole 121 is provided on the middle bottom plate 12. The upper positioning hole 221 is used to fix the support top plate 2 to the building, and the lower positioning hole 121 is used to fix the support bottom plate 1 to the building.

[0031] Furthermore, it also includes a bonding plate 6, which includes a structural plate 61 and a friction plate 62 that are arranged in layers and fixedly connected, and a surface of the friction plate 62 is provided with a plurality of anti-skid grooves 63 arranged in the front-to-back direction, and the bonding plate 6 is fixed to the lower surface of the supporting bottom plate 1 and the upper surface of the supporting top plate 2, and the friction plate 62 is arranged toward the outside.

[0033] Furthermore, the bonding plate 6 is divided into blocks and fixed on the left top plate 21, the middle top plate 22 and the right top plate 23, and the bonding plate 6 is divided into blocks and fixed on the left bottom plate 11, the middle bottom plate 12 and the right bottom plate 13.

During use, when the seismic energy dissipation damper as a whole is subjected to the shaking and stress of the building structure in the directions of the two sides to which it is bonded, the cross damping components 4 matched on both sides and the central damping component 3 located in the center can form energy dissipation buffers at the angles on both sides.

[0037] In summary, the anti-seismic energy dissipation damper for buildings provided by the utility model has the following beneficial effects:

[0038] 1. The cross damping components 4 are symmetrically distributed on both sides of the seismic energy dissipation damper. The cross damping components 4 are connected and hinged to the central damping component 3 through the structural axis 5. When the seismic energy dissipation damper as a whole is subjected to the shaking and stress of the building structure in the directions of the two sides, the damping components 31 on both sides cooperate with the damping component 31 vertically arranged in the center to form energy dissipation buffers at the angles of the two sides, thereby completing the seismic energy dissipation at multiple angles, thereby further improving the stability of the building structure support;

[0039] 2. The seismic energy dissipation damper can be positioned at the supporting position in the building structure through the upper positioning hole 221 and the lower positioning hole 121, and can be used after the installation is completed. During the supporting process, the central damping component 3 is used to reduce vibration and dissipate energy for the supporting top plate 2, the supporting bottom plate 1 and the supporting part of the building structure to keep the support stable;

[0040] 3. During the use of the supporting top plate 2, supporting bottom plate 1 of the seismic energy dissipation damper and the building structure, the friction plate 62 connected to the supporting top plate 2 and supporting bottom plate 1 also maintains a fit state with the surface of the building structure. During the supporting process, the anti-slip grooves 63 distributed on the surface of the friction plate 62 are used to increase the fit friction force, thereby maintaining the stable support fit between the seismic energy dissipation damper and the surface of the building structure.
