Description

Technical Field

[0001] The utility model belongs to the technical direction of building equipment, and specifically relates to an anti-seismic energy dissipation damper for a building structure. Background Art

[0002] In the construction field, viscous dampers are often installed in buildings for shock absorption purposes. Viscous dampers are generally composed of a cylinder body and a piston rod. A piston is connected to one end of the piston rod, and the cylinder body is filled with silicone oil. The viscous resistance generated when the silicone oil passes through the piston consumes the energy transmitted from the outside and reduces the vibration generated by the building.

[0003] The existing technology has the following problems:

[0004] 1. The existing dampers on the market are sometimes not installed in the right position, which causes inconvenience to the workers and low work efficiency;

[0005] 2. Some existing dampers on the market have simple structures, usually with only a single spring inside. The damper structure itself is easily impacted, and the overall anti-seismic effect is poor. Utility Model Content

[0006] The utility model aims to provide an anti-seismic energy dissipation damper for a building structure in view of the existing device, so as to solve the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: an anti-seismic energy dissipation damper for a building structure, comprising a pin head, a cylinder body is arranged on one side of the pin head, a pin hole is opened on the outer surface of the pin head, L-shaped connecting frames are arranged on both sides of the pin head, and a pin shaft is arranged inside the L-shaped connecting frame.

[0008] The bottom of the L-shaped connecting frame is fixedly connected with a connecting seat, the bottom of the connecting seat is fixedly installed with a telescopic rod, and the bottom of the telescopic rod is fixedly connected with a connecting plate.

[0009] The utility model further describes that a fastening groove is provided on the outer surface of the connecting seat, and the fastening groove is symmetrically arranged with the L-shaped connecting frame as the vertical center line as the symmetry axis, and a bolt is arranged inside the connecting seat, and the structure between the bolt and the fastening groove is wedged.

[0010] The above technical solution is adopted, in which fastening grooves and bolts are provided to facilitate workers to install and fix the connecting plate by bolts.

[0011] The utility model further illustrates that a piston rod is installed on the inner wall of the cylinder body, one end of the pin head is fixedly connected to the piston rod, and the pin head is specifically made of stainless steel.

[0012] By adopting the above technical solution, the weight pressure is transmitted to the piston rod through the pin head.

[0013] The utility model further illustrates that a piston is installed on the outer wall of the piston rod, and the piston is specifically circular and fits around the inner wall of the cylinder body.

[0014] The above-mentioned technical scheme is adopted, in which the cooperation between the piston rod and the piston causes friction, bending, torsion, shearing, viscous hysteresis deformation, elastoplastic hysteresis deformation, and viscoelastic hysteresis deformation to absorb the energy generated in the vibration input structure, thereby effectively avoiding damage or collapse of the structure and achieving the purpose of shock absorption control.

[0015] The utility model further illustrates that one side of the pin head is movably connected to a first shock-absorbing spring, the bottom of the first shock-absorbing spring is movably connected to an end cover, and the bottom of the end cover is movably connected to a second shock-absorbing spring.

[0016] The above-mentioned technical scheme is adopted. The cooperation of the first shock-absorbing spring and the second shock-absorbing spring in this scheme is beneficial to preventing the rapid piston movement from causing excessive internal heat when blocking an earthquake, and the damping coefficient of the damping fluid is reduced. When the end cover moves, it will drive the first shock-absorbing spring to synchronously compress the second shock-absorbing spring, and the second spring will assist in absorbing vibrations, and the stability of the end cover when moving is improved.

[0017] The utility model further illustrates that a connector is arranged on one side of the cylinder body, a return spring is movably connected to the top of the connector, a sealing retaining ring is movably connected to the inner surface of the end cover, and a sealing ring is movably connected to the inner surface of the connector.

[0018] The above-mentioned technical scheme is adopted. In this scheme, the return spring makes the piston rod easily collide with the return spring and the end cover through the return spring to further buffer and reduce the shock to prevent the surface damage of the piston rod caused by hard collision, thereby further improving the safety factor and reducing the wear of the piston rod. Through the cooperation of the sealing retaining ring and the sealing ring, it mainly plays a sealing role to ensure that the viscous damping fluid does not flow out of the cylinder body.

When the end cover moves, it will drive the first shock-absorbing spring to compress the second shock-absorbing spring synchronously, and the second spring is used to assist in absorbing vibrations, and the stability of the end cover when moving is improved.
