Description
Technical field:
The utility model relates to the damping field that builds a bridge, and is a kind of viscoplasticity lead for retractable pencil damper.
Background technology:
In order to reduce the huge disaster that earthquake brings the mankind, both at home and abroad to building with bridge mainly from antidetonation with subtract shock insulation two aspects and carried out a large amount of research and practice, wherein subtract the shock insulation field and obtained bigger achievement.This is mainly because of the use of dissimilar damping energy dissipation dampers.Viscoelastic damper is made up of three block plates and the viscoelastic material that is clipped in the steel plate, its horizontal rigidity is little, energy consumption and displacement little (general maximum displacement only is 60mm) are not suitable for the big power consumption of increasing highrise building and long-span bridge beam and the needs of big displacement quantity.And fracture appears in lead damper easily under the situation of cyclic reverse loading and big displacement, finally loses damping action.At present, be that viscoelastic damper or lead damper and visous damping device all exist the shortcoming that is difficult for being used in combination.
The utility model content:
The purpose of this utility model is in order to overcome the deficiency of above-mentioned damper, to provide a kind of simple in structure, and damping energy dissipation is clear and definite clear, and use capable of being combined, realizes the viscoplasticity lead for retractable pencil damper of big displacement, big damping demand.
The utility model is achieved in that
The utility model viscoplasticity lead for retractable pencil damper, comprise upper sealing plate, following shrouding, be positioned at, at least two layers of compound with it viscoelastic layer between following shrouding, the compound with it steel plate layer of putting more energy into is arranged between viscoelastic layer and viscoelastic layer, through last, at least one through hole of following shrouding and each viscoelastic layer and the steel plate layer of putting more energy into, press-fit the lead for retractable pencil in through hole, viscoelastic layer can adopt natural rubber or neoprene or acrylonitrile-butadiene rubber to make, on, following shrouding is used for linking to each other with junction plate, the at least two layers of viscoelastic layer and the steel plate layer of putting more energy into make damper can bear certain vertical pressure, and play the sealing lead for retractable pencil purpose, allow the lead for retractable pencil can shear failure simultaneously, the restoring force of multilayer rubber has good facilitation to the recrystallization of lead for retractable pencil, the thickness and the number of plies that increase rubber can realize bigger displacement deformation, and diameter by adjusting lead for retractable pencil and quantity and a plurality of damper are used in combination and can increase damping and increase power consumption.
Above-mentioned viscoplasticity lead for retractable pencil damper be shaped as cylinder.
Above-mentioned viscoplasticity lead for retractable pencil damper be shaped as cuboid.
The periphery of above-mentioned upper and lower shrouding protrudes in the elastic layer and the steel plate layer of putting more energy into respectively, with build a bridge easy to connect.
Have in the above-mentioned damper and upper and lower shrouding and viscoelastic layer and the compound anti-aging elastic protective layer of steel plate layer periphery that puts more energy into.
The utility model damper structure is succinct, and damping energy dissipation is clear and definite clear, and damping energy dissipation can directly be realized by diameter and the quantity of adjusting lead for retractable pencil.And can be used in combination by a plurality of dampers, realize the demand of the big damping of big displacement, have good economy and social value.
