Description

Technical Field

[0001] The utility model belongs to the technical field related to dampers, and specifically relates to a wall type composite damper. Background Art

[0002] The wall-type damper is a damper made of low-carbon steel with low yield strength as an energy-absorbing element. Its basic principle is that when the structure is shaken by an earthquake, certain types of components in the building structure (both ends undergo relative deformation, and drive the energy-absorbing elements of the damper installed in between to undergo reciprocating plastic deformation, so that the deformation first occurs in the energy dissipation and shock absorption device, consuming most of the earthquake energy, thereby reducing the damage to the main structure. The shear damper is a displacement damper, and the general connection forms are support type and wall type. When using a wall-type shear damper, the embedded parts are generally arranged in the concrete walls at the upper and lower ends. Patent No. CN201821819193.3 publishes a wall The present invention relates to a viscous damper, which mainly consumes and reduces vibration through the cooperation of two shear steel plates and a partition plate, and the damping viscous liquid. Both the shear steel plates and the partition plates are flat plate structures. The tonnage and performance of the damper are changed mainly by changing the thickness, size and number of the shear steel plates and the number of partition plates. For installation locations with relatively small wall thickness, it is not convenient to increase the thickness of the shear steel plates and the number of partition plates, and the use requirements of increasing the tonnage of the damper cannot be met. The relative plate surfaces of the two shear steel plates 9 are respectively provided with limit blocks 5, which abut against and contact the corresponding partition plates 10 to limit the horizontal direction, so that the damper cannot effectively dissipate energy and reduce vibration in the horizontal direction.

[0003] In view of this, the present utility model is proposed. Utility Model Content

The positions of the matching convex ribs 21 and the matching grooves 1 20 correspond to each other, and the positions of the matching convex ribs 16 and the matching grooves 17 correspond to each other, so as to cooperate with each other to realize energy dissipation and shock absorption.

[0026] Among them, there are spacing gaps between the corresponding surfaces of the matching convex rib 16 and the matching groove 2 17, and there are spacing gaps between the corresponding surfaces of the matching convex rib 21 and the matching groove 1 20. The accommodating chamber 5 and the spacing gaps are filled with damping viscous liquid to dissipate vibration energy.
