Abstract
The invention discloses a sliding isolation bearing with friction materials replenishable. The sliding isolation bearing comprises an upper slider and a lower slider. A friction material layer is disposed between the upper slider and the lower slider. The upper slider is provided with a plurality of through holes. A friction material replenishing structure is mounted in each through hole and comprises a sleeve, a screw plug, an elastic part, a moving baffle and friction material layer stock, wherein the screw plug, the elastic part, the moving baffle and the friction material layer stock are mounted in an inner cavity of the sleeve sequentially from top to bottom. Each screw pug is connected with the corresponding sleeve in a threaded manner and blocks the upper port of the sleeve, each elastic part is compressed between the corresponding screw plug and the corresponding moving baffle, and each friction material layer stock contacts with the corresponding friction material layer. The sliding isolation bearing has long-lasting good friction performance and avoids being replaced after a quake.
Description
Technical field
The present invention relates to a kind of sliding isolated bearing, relate in particular to a kind of sliding isolated bearing that supplements friction material.
Background technology
Recently earthquake is continuous all over the world, cause great injury and loss for people and building, traditional method is to rely on the strength and stiffness of structure self to resist earthquake, rely on distortion and the damaged energy that imports superstructure into that consumes of structural element, this method often can not be accomplished no collapsing with strong earthquake sometimes, and the infringement of structure in earthquake is huge often, has greatly surpassed society and owner's tolerance range.
Seismic isolation technology is a kind of effective ways that seismic energy imports building into that reduce, and can protect superstructure, reduces the infringement of structure in earthquake, thereby effectively reduces or prevent personal damage.What application was commonplace at present is laminated rubber steel plate shock isolating pedestal, and its technology is relatively ripe, but price is also higher, and has the problems such as durability, weatherability.Sliding and shock isolation is also one of important seismic isolation technology, can effectively reduce to be input to the geological process of superstructure, reduces the stratified deformation in house, top.Sliding isolated bearing generally by upper sliding plate, down-shift board, interface friction material, connecting bolt and (or) stopping means forms, upper sliding plate on down-shift board, interface friction material in the time of between the two.With the General Purpose Rubber bearing, compare, sliding isolated bearing cheap, easy to make, overall height is little, good endurance.In sliding isolated bearing, the interface friction performance between upper sliding block is one of its important indicator.For the application type friction material on shoe surface, along with the increase of slippage number of times in earthquake, the continuous loss of friction material, and be not easy up between down-shift board to add the interface friction material, often cause the slide surface friction factor unstable, thereby affect the service behaviour of sliding isolated bearing.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of sliding isolated bearing that supplements friction material, can keep lastingly the frictional behaviour that sliding isolated bearing is good, avoided the replacing of sliding isolated bearing after the shake.
Technical scheme: for achieving the above object, the technical scheme that provides of the present invention is as follows:
A kind of sliding isolated bearing that supplements friction material, comprise top shoe and sliding block, between top shoe and sliding block, is provided with friction material layer, on described top shoe, has some through holes, and the friction material supplementing structure is installed in through hole; Described friction material supplementing structure comprises sleeve and is arranged on successively plug screw, elastic component, sideboard and the friction material layer raw material in barrel bore from top to bottom, described plug screw is connected with bush whorl, seal the upper port of sleeve, elastic component is compressed between plug screw and sideboard, and described friction material layer raw material contacts with friction material layer.
Under the effect of elastic component, make sideboard that the friction material layer raw material is pressed on friction material layer, for supplementing the friction material layer between top shoe and sliding block, kept the frictional behaviour that sliding isolated bearing is good.
Further, described top shoe and sliding block adopt lithotome, artificial stone or steel plate; Described top shoe radius is 100mm, and thickness is 50mm; Described sliding block radius is 250mm, and thickness is 50mm.
Further, the material of described plug screw, elastic component, sideboard and sleeve is steel; Described sleeve outer diameter is 20mm, and wall thickness is 4mm; Described elastic component is spring or high-elastic rubber.
Further, described friction material layer raw material adopts the mixture of molybdenum bisuphide solid, graphite solid or paraffin solid, molybdenum bisuphide solid and graphite solid as lubriation material; Described through hole is arranged on top shoe by annular array or rectangular array.
Beneficial effect: 1) with existing sliding isolated bearing, compare, the sliding isolated bearing that the friction material supplementing structure is set can keep the frictional behaviour that sliding isolated bearing is good lastingly;
2) the friction material supplementing structure is made and is installed simply, is easy to realize;
3) the friction material supplementing structure is positioned at top shoe, and environment is single, and good endurance can not affect application life of sliding isolated bearing;
4) in earthquake, loss along with relative sliding and the friction material layer of upper and lower slide block, elastic construction has a decrement in advance, extrusion friction material layer raw material is filled up into the contact surface of top shoe and sliding block, increase frictional behaviour, make the sliding isolated bearing that the friction material supplementing structure is set can continue to use, avoided the replacing of bearing.
