Abstract
The present invention relates to a lever viscoelastric damper, and is characterized by that the viscoelastic damping material are respectively fixedly connected on the both sides of lower end of the lever pendulum, and the restrained steel plates are respectively fixedly connected on the two sides of two viscoelastic damping material layers, and on the middle of upper portion of the lever pendulum a fulcrum hole is opened, and a slideway is cut on the top of the lever pendulum, and one end of the slide bar can be inserted into the slideway. Said invention can magnify the relative deformation of triangular steel piece of the top board several times, and can transfer the magnified quantity to the viscoelastic damping material, then the energy can be consumed by said damping material so as to reduce the wind-vibration effect and seismic reaction of building and raise the anti seismic behavior of building.
Description
The invention belongs to the device that reduces to be subjected to dynamic excitation and cause building deformation.
The effectiveness in vibration suppression of existing viscoelastic damper is not good, and 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, is out of shape big or small limitedly, has limited giving full play to of viscoelastic material energy dissipation capacity.
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, and makes 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 the triangle steel part, 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 utility model also has rational in infrastructure, and good damping result is installed simple advantage.
Fig. 1 is a front view of the present invention, and Fig. 2 is its lateral view, and Fig. 3 is the structural representation that itself and building are installed.
Embodiment: present embodiment is made up of constraint steel plate 1,2, visco-elastic damping material layer 3,4, 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, and 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, has a fulcrum hole 7 in the middle of the top of lever pendulum 5, has a chute 8 at the top of lever pendulum, and an end of slide bar 6 is inserted in the chute 8.Give for 9 times at the top board of building frame during application and be embedded with triangle steel part 10, the other end of slide bar 6 is fixed on the triangle steel part 10, and the fulcrum hole 7 of lever pendulum 5 is fixed on the summit of herringbone 11.
