Abstract
The utility model relates to a lead core high-damping rubber seismic mitigation and absorption support seat. A restraint spring or a carbon fiber fabric wraps the outer wall of a lead core, a high-damping rubber layer and a reinforcing steel plate are arranged on the periphery of the lead core in a laminating mode, a damping ratio can reach more than 30%, and therefore small horizontal shearing deformation is needed for exerting the damping and energy consuming effect, the deformation amount of the support seat is small in an earthquake, the requirement on expansion amount of a bridge end expansion joint is small, the manufacturing cost of the expansion seam can be lowered, displacement of a bridge is lowered, the spring and the high-damping rubber layer assist restoration of deformation of the lead core together, time for restoration of the deformation of the support seat is shortened, residual deformation after an earthquake is small, and restoration of the support seat and restoration of the bridge supported by the support seat can be achieved without jacking of a jack and other methods.
Description
Technical field
The utility model belongs to bridge and subtracts the seismic isolation technology field, particularly relates to a kind of lead for retractable pencil high-damping rubber vibration absorption and isolation support.
Background technology
Domestic bridge vibration absorption and isolation support mainly contains lead core rubber support and high-damp rubber support at present.This two classes vibration absorption and isolation support is mainly the seismic forces that recently increases energy-dissipating property and reduce bridge construction itself by improving damping.
Lead core rubber support is by adding highly purified lead for retractable pencil to improve the damping ratio of bearing in common laminated rubber bearing, and high-damp rubber support is to utilize the higher high-damping rubber material of damping ratio to replace General Purpose Rubber to improve the damping ratio of bearing.
The damping ratio of lead core rubber support and high-damp rubber support is only 15% left and right, need to be out of shape to bring into play its damping energy dissipation effect by larger horizontal shear, during earthquake, the deflection of bearing itself is large, bridge construction is when installing above-mentioned two kinds of bearings, and the stroke that needs to strengthen the beam-ends shrinkage joint adapts to its larger horizontal shear distortion.
During earthquake, utilize metallic lead to recover distortion in the characteristic that normal temperature can recrystallization after lead core rubber support surrender, but because the elastomeric material modulus of elasticity of parcel around lead for retractable pencil is little, effect of contraction is low, the recovery deformation time of lead core rubber support is slower, permanent set after causing shaking is bigger than normal, need to adopt the mode auxiliary support such as jack pushing tow with and the bridge that supports reset.
The utility model content
In order to overcome the existing deficiency of lead core rubber support of the prior art, the utility model provides a kind of deflection of bearing and supporting bridge thereof can significantly improve the bearing damping ratio and reduce earthquake the time, and after shake the lead for retractable pencil high-damping rubber vibration absorption and isolation support of self-resetting fast.
The technical scheme of technical solution problem is: in the inboard of upper junction plate, paste upper junction plate and be provided with upper sealing plate, be provided with the lower connecting plate with the upper junction plate symmetry below lower shrouding, in the inboard of lower connecting plate, lower shrouding is set, be processed with the lead for retractable pencil hole at the center of upper sealing plate and lower shrouding, be provided with lead for retractable pencil high-damping rubber assembly between upper sealing plate and lower shrouding;
The two ends that above-mentioned lead for retractable pencil high-damping rubber assembly is lead for retractable pencil extend to respectively in the lead for retractable pencil hole of upper sealing plate and lower shrouding, outer wall at lead for retractable pencil is enclosed with restraint layer, be provided with the put more energy into steel plate vertical with the lead for retractable pencil central axis in the restraint layer periphery, sulfuration has the high-damping rubber layer around the steel plate of putting more energy into.
Above-mentioned restraint layer is restricted spring or carbon fibre fabric.
The above-mentioned steel plate of putting more energy into is at least 2 layers.
The high-damping rubber layer edge at two ends, above-mentioned up and down extends to the periphery of upper sealing plate and lower shrouding, aligns with upper sealing plate and lower shrouding respectively.
Above-mentioned upper sealing plate and lower shrouding connect with upper junction plate and lower connecting plate respectively by threaded fastener.
The damping ratio of above-mentioned high-damping rubber layer 〉=10%, and≤18%.
lead for retractable pencil high-damping rubber vibration absorption and isolation support of the present utility model, by parcel restricted spring or carbon fibre fabric on the outer wall of lead for retractable pencil, and be with the high-damping rubber layer and put more energy into the stacked setting of steel plate at the outer of lead for retractable pencil, damping ratio can reach more than 30%, and only need just can bring into play its damping energy dissipation effect by less horizontal shear distortion, during earthquake, the deflection of bearing itself is little, stroke demand to bridge end shrinkage joint is also little, can reduce the cost at shrinkage joint, reduce the displacement of bridge, and spring and the distortion recovery of auxiliary lead for retractable pencil jointly of high-damping rubber layer, accelerated the time of bearing deformation-recovery, permanent set after shake is little, do not need to adopt the mode auxiliary support such as jack pushing tow with and the bridge that supports reset.
