Abstract
The utility model relates to a shock-absorbing rubber supporting base capable of supplying bigger displacement and belongs to the field of highway bridge accessory equipment. The shock-absorbing rubber supporting base is composed of a shock-absorbing rubber supporting base main body, a sliding pair and upper and lower connecting steel plates, wherein the sliding pair is composed of a stainless steel plate and a polytetrafluoroethylene plate and is arranged between the upper connecting steel plate and the shock-absorbing rubber supporting base main body; the upper surface of the stainless steel plate of the sliding pair is connected with the lower surface of the upper connecting steel plate; the lower surface of the polytetrafluoroethylene plate of the sliding pair is connected with the upper surface of the shock-absorbing rubber supporting base main body; the lower surface of the shock-absorbing rubber supporting base main body is connected with the upper surface of the lower connecting steel plate; and under a normal running condition of a bridge, the deformation generated by a horizontal force is endured by the sliding pair. When an earthquake happens, the bridge generates a great deformation under the influence of the earthquake force and the deformation is endured by the sliding pair and the supporting base. The problem that the supporting base is differently deformed under the effects of the horizontal forces in different magnitudes is solved by the shock-absorbing rubber supporting base, so that the design is widely applied to various shock-absorbing rubber supporting bases, such as, the supporting base free from core supporting base, the supporting base having the core supporting base and the supporting base made of high-damping rubber.
Description
Technical field
A kind of shock insulation rubber bearing that subtracts that big displacement can be provided of the utility model belongs to highway bridge ancillary service field.
Background technology
Earthquake is the unavoidable a kind of natural phenomena of human society, and ruinous earthquake brings great harm and loss to the people's lives and property.Construct a bridge in the earthquake prone areas and must consider geological process, adopt subtract shock insulation rubber bearing after, when earthquake takes place, can alleviate or isolate earthquake intensity, the loss that minimizing brings owing to earthquake.Subtracting shock insulation rubber bearing has good distortion (displacement), resets and supporting capacity; Thereby be used for bridge and have the good shock insulation function that subtracts.
But receive (beam body) on the bridge, the restriction of following (bridge pier) portion physical dimension and the influence of job practices; The common shock insulation rubber bearing that subtracts is satisfying under the homeostatic prerequisite; And in normal use because the influence of factors such as the temperature difference, concrete shrinkage and creep; Make bearing under the situation that earthquake does not take place, just produce yield deformation; Cause bearing to be in fatigue state for a long time, and the moderate finite deformation (displacement) that superstructure produces when when earthquake takes place, being difficult to satisfy earthquake and taking place, so that can not reach the desirable isolating affection that subtracts.
Therefore; Need the existing shock insulation rubber bearing that subtracts is promoted and innovates; Can not only overcome in the normal use because of the temperature difference, contingent surrender when concrete shrinkage and creep produces distortion; Avoid bearing to cause fatigue failure, and when earthquake takes place, can have stronger deformability, play the due isolating affection that subtracts.
The utility model content
The purpose of the utility model provides a kind of shock insulation rubber bearing that subtracts that big displacement can be provided, and bearing can be satisfied do not produce fatigue failure when deforming under the normal operating condition, can when earthquake takes place, have stronger deformability again.
The utility model purpose realizes through following technical scheme:
The utility model is by subtracting the shock insulation rubber bearing body; Sliding pair be connected steel plate up and down and form; Characteristics are that sliding pair is arranged on and connects between steel plate and the seat body, and this sliding pair is made up of corrosion resistant plate and polyfluortetraethylene plate, the corrosion resistant plate upper surface of sliding pair with on be connected surperficial connection under the steel plate; The polyfluortetraethylene plate soffit of sliding pair with subtract the shock insulation rubber bearing body on the surface is connected, seat body soffit with under be connected the connection of steel plate upper surface.
There is positive stop in the outside of above-mentioned corrosion resistant plate.
The distortion that horizontal force produces under the normally operation situation of the design's bridge is born by sliding pair; When earthquake, receive influencing bridge and will producing moderate finite deformation (displacement) of seismic forces, this distortion is born by sliding pair and bearing jointly.The utility model bearing can satisfy and not produce fatigue failure when deforming under the normal operating condition, can when earthquake takes place, have stronger deformability again.
Therefore, the utility model has solved bearing and has produced the problem of different distortion owing to suffered horizontal force varies in size.The utility model is widely used, be applicable to as the centreless bearing, have core bearing and high damping rubber all types of subtract shock insulation rubber bearing.

The specific embodiment
How further specify the utility model in conjunction with accompanying drawing implements:
The utility model comprise by multilayer rubber plate and steel sheet and up and down shrouding sulfuration all-in-one-piece prop up seat body 3, on connect steel plate 1, following connection steel plate 5, sliding pair and positive stop 4.And sliding pair is made up of corrosion resistant plate 2 and polyfluortetraethylene plate 6, is arranged on to connect between a steel plate 1 and the seat body 3, and corrosion resistant plate 2 is welded on the soffit that connects steel plate 1, and polyfluortetraethylene plate sticks on the upper surface of a seat body 3.Positive stop 4 is arranged on the outside of corrosion resistant plate, is welded on the soffit that connects steel plate 1.(as shown in Figure 1)
Under the normally operation situation of bridge, the X that under horizontal force Fc effect, will deform connects steel plate and slides with the beam body on this moment, as shown in Figure 2.The size of this deflection X is provided by bridge design department.
During earthquake; Brisance Fz significantly (Fz＞＞Fc) effect under; At first sliding pair slides earlier; Because the deformation values of sliding pair can not satisfy the requirement of distortion far away, reach deformation values Y (displacement) and produce surrender at larger earthquake power effect undersetting, the size of this deformation values Y is provided by bridge design department.
In order to prevent to put in place in larger earthquake power effect lower slider distortion, and the bearing surrender when being in the starting stage beam body skid off bearing, so be out of shape the correspondence position that puts in place and be provided with positive stop 4 sliding.
Claims (2)
1. one kind can provide the shock insulation rubber bearing that subtracts than big displacement; By subtracting the shock insulation rubber bearing body; Sliding pair be connected steel plate up and down and form; It is characterized in that sliding pair is arranged on connects between steel plate and the seat body, and this sliding pair is made up of corrosion resistant plate and polyfluortetraethylene plate, the corrosion resistant plate upper surface of sliding pair with on be connected surperficial connection under the steel plate; The polyfluortetraethylene plate soffit of sliding pair with subtract the shock insulation rubber bearing body on the surface is connected, seat body soffit with under be connected the connection of steel plate upper surface.
2. a kind of shock insulation rubber bearing that subtracts that big displacement can be provided according to claim 1 is characterized in that there is positive stop in the corrosion resistant plate outside of sliding pair.
