Abstract
The utility model discloses a variable -stiffness plate rubber support, including connector plates, shrouding, middle glue film, steel core, solid steel sheet and protection rubber, connector plates passes through countersunk screw and is connected with the shrouding, the setting of protection rubber is peripheral at the shrouding, middle glue film and solid steel sheet are each other at a distance from piling up to be located inside the protection rubber, what the steel core was even arranges between two connector plates. The setting of protection rubber is around the support to protection shrouding, middle glue film, solid steel sheet do not receive pollutions such as air and ultraviolet ray. The utility model discloses overcome the not enough of active standard support, can make the bridge at operation or the during the earthquake common even atress of each pier, improve the security and the life of bridge, simultaneously the utility model has the advantages of being simple in structure and convenient in operation, economical and practical has higher economic benefits and social.
Description
Technical field
This utility model relates to supporting bridge technical field, is specifically related to a kind of variation rigidity laminated rubber bearing.
Background technology
Bridge increasingly tends to lightness, economy, and the application of flexible pier is exactly one of classic approach.Aseismic Design Theory is thought: if each bridge pier same in beam structure undertakes horizontal earthquake active force the most equably, then can be substantially reduced the antidetonation to anchor block to rely on, reduce the construction cost of bridge, also can be promoted on the aesthetic property of bridge simultaneously.In order to make each bridge pier shared horizontal applied force, then need the horizontal rigidity of each pier is controlled.If to accomplish further uniformly to undertake, then require that the combined horizontal rigidity of each pier reaches unanimity.The combined horizontal rigidity of pier is " pier shaft horizontal rigidity+bearing horizontal rigidity ".
The laminated rubber bearing selected according to existing industry standard JT/T663-2006, bearing to vertical bearing capacity of the same race, when highly consistent, it is vertical, horizontal rigidity is consistent or basically identical, if needing to change one of them parameter (vertical bearing capacity, vertical rigidity or horizontal rigidity), another two parameters then can change, and the most linear.
For the bridge consistent across footpath, pier shaft height is identical, such bearing can meet use demand, and they either vertical bearing capacity, vertical rigidity or horizontal rigidities, it is unanimously correct for being designed between each pier.But under more topographic features, same bridge may have the pier shaft of differing heights, and the bridge especially for area, mountain area is all the more so.To this, pier shaft height consistent across footpath same bridge pad not etc., its demand is, vertical bearing capacity is identical with vertical rigidity requirement, and in order to integrin pier shaft horizontal rigidity is designed to identical, to meet the Aseismic Design demand of each pier shared horizontal force, in the case of the horizontal rigidity of pier shaft own is inconsistent, then needs to adjust the horizontal rigidity of bearing, make combined horizontal rigidity reach consistent.
Utility model content
The purpose of this patent is the deficiency overcoming working standard bearing, a kind of stiffness variable laminated rubber bearing is provided, this bearing can make bridge common uniform stressed of each bridge pier when operation or earthquake, improve safety and the service life of bridge, this utility model simple in construction, easy to operate simultaneously, economical and practical, there are higher economic benefit and social benefit.Described steel core is arranged between two junction steel plates uniformly, and required for this utility model, horizontal rigidity is relatively big, uses structure of steel pole to adjust, and steel core quantity requires relevant to steel core diameter with horizontal rigidity.
This utility model is realized in; a kind of variation rigidity laminated rubber bearing of structure; it is characterized in that: include junction steel plate, shrouding, intermediate gelatine layer, steel core, solid steel plate and protection rubber; described junction steel plate is connected with shrouding by sunk screw; it is peripheral that described protection rubber is arranged on shrouding; described intermediate gelatine layer and the spaced stacking of solid steel plate, and be positioned at inside protection rubber, described steel core is arranged between two junction steel plates uniformly.Protection rubber is arranged on around bearing, to protect shrouding, intermediate gelatine layer, solid steel plate not to be polluted by air and ultraviolet etc..
According to variation rigidity laminated rubber bearing described in the utility model, it is characterised in that: described junction steel plate is connected by anchor bolt sleeve.
According to variation rigidity laminated rubber bearing described in the utility model, it is characterised in that: described intermediate gelatine layer and the spaced stacking of solid steel plate, and and protect rubber to form entirety, referred to as a support body through sulfuration.
According to variation rigidity laminated rubber bearing described in the utility model, it is characterised in that: the height of described steel core is consistently less than the end face distance of two shroudings.This utility model increases bearing horizontal rigidity by solid steel plate with steel core combination；Thus reach the demand of bridge stiffness and make the effect of bridge each bridge pier all stress.
This utility model has the advantages that this utility model passes through to improve and provides a kind of variation rigidity laminated rubber bearing; including junction steel plate, shrouding, intermediate gelatine layer, steel core, solid steel plate and protection rubber; by reasonably design; not only can reach to make bridge common uniform stressed of each bridge pier when operation or earthquake; and bridge construction construction cost can be substantially reduced, effectively reduce the overall cost of bridge.Simultaneously because each pier face profile size can be accomplished unanimously so that bridge also can get certain lifting on aesthetic property.
After improvement, described steel core is arranged between two junction steel plates uniformly, and required for this utility model, horizontal rigidity is relatively big, uses structure of steel pole to adjust, and steel core quantity requires relevant to steel core diameter with horizontal rigidity.This utility model has simple in construction, easy to operate feature.Under the conditions of overall dimensions, bearing capacity, vertical rigidity are immovable, the combined horizontal rigidity of bridge pier is reached to change by changing bearing horizontal rigidity, make cross section bridge pier horizontal rigidity identical, the most not etc. consistent, to reach jointly to participate in bridge to subtract function of shock insulation, greatly reduce bridge construction construction cost, economical and practical, there are higher economic benefit and social benefit, are suitable for promoting the use of.
