Abstract
The present invention relates to a lever viscoelastic damper. Viscoelastic damping material layers 3, 4 are respectively and fixedly connected to both sides of the lower end of a lever pendulum 5, constraint steel plates 1, 2 are respectively and fixedly connected to both sides of the two viscoelastic damping material layers, a fulcrum hole 7 is arranged at the middle of the upper part of the lever pendulum, the top of the lever pendulum is provided with a sliding groove 8, and one end of a sliding rod is inserted in the sliding groove. The present invention can magnify the relative deformation at a triangular steel piece 10 on a roof plate severalfold, the magnification energy is transferred to a viscoelastic damping material which consumes the energy, the wind-shock response and the earthquake response of buildings are further reduced, and the shock-proof performance of the buildings is enhanced. The present invention also has the advantage of simple installation.
Description
Technical field: the invention belongs to the device that reduces to be subjected to dynamic excitation and cause building deformation.
Background technique: the effectiveness in vibration suppression of existing viscoelastic damper is not good, reason is that relative deformation that its viscoelastic material is experienced is the relative deformation between damper links to each other a little with structure, the distortion size is limited, has limited giving full play to of viscoelastic material energy dissipation capacity.
Summary of the invention: the objective of the invention is to develop a kind of lever viscoelastic damper, relative deformation between this damper can link to each other a little with structure damper is amplified, make the viscoelastic material energy dissipation capacity give full play to, and then the wind that more effectively reduces structure shake reaction and earthquake response.The present invention is made up of constraint steel plate, visco-elastic damping material layer, lever pendulum, slide bar.The visco-elastic damping material layer is cemented in the both sides, lower end of lever pendulum respectively, and two blocks of constraint steel plates are cemented in the both sides of two visco-elastic damping material layers respectively.Top at the lever pendulum has a fulcrum hole, has a chute at the top of lever pendulum, and an end of slide bar is inserted in the chute.Give under the top board of building frame during application and be embedded with the triangle steel part, the other end of slide bar is fixed on three angle members, and the fulcrum hole of lever pendulum is fixed on the summit of herringbone.The present invention can amplify several times with the relative deformation at triangle steel part place on the top board, this amplification quantity is passed to visco-elastic damping material, visco-elastic damping material falls this energy dissipation, and then the wind that has reduced fabric structure shake reaction and earthquake response, has improved the antivibration ability of building.The present invention also has rational in infrastructure, and good damping result is installed simple advantage.
Description of drawings: Fig. 1 is a plan view of the present invention, and Fig. 2 is its side view, and Fig. 3 is the structural representation that itself and building are installed.
Embodiment: present embodiment is made up of constraint steel plate 1, constraint steel plate 2, visco-elastic damping material layer 3, visco-elastic damping material layer 4, lever pendulum 5, slide bar 6.Visco-elastic damping material layer 3,4 is cemented in the both sides, lower end of lever pendulum 5 respectively, constraint steel plate 1,2 is cemented in the both sides of two visco-elastic damping material layers 3,4 respectively, lever pendulum 5 is a trapezium structure, in the middle of the top of lever pendulum 5, have a fulcrum hole 7, top at the lever pendulum has a chute 8, and an end of slide bar 6 is inserted in the chute 8.Lever viscoelastic damper gives for 9 times at the top board of building frame when using and is embedded with triangle steel part 10, the other end of the slide bar 6 of lever viscoelastic damper is fixed on the triangle steel part 10, and the fulcrum hole 7 of the lever of lever viscoelastic damper pendulum 5 is fixed on the summit of herringbone 11.
