Description
Technical field
The utility model relates to building field, especially relates to a kind of neoprene bearing.
Background technology
Bearing refers to the weight in order to supporting container or equipment, and makes its support unit that is fixed on certain position, vibration and seismic (seismal also will bear operation time.Neoprene bearing is that rubber and steel sheet are combined closely and formed, for supporting bridge weight.Current pot rubber bearing is mainly that the steel basin that rubber bodies is placed in to sealing makes its three dimension stress and produces huge counter-force and utilize the Incoercibility of rubber to bear huge vertical lotus.Rely on the low-friction coefficient between polytetrafluoroethylene (PTFE) and stainless steel to realize the horizontal movement of bridge and the flexibility of rotation simultaneously.
Traditional neoprene bearing damping effect is poor, uses after certain hour, easily piles up dust and other impurities on movable plate, causes junction plate and upper mounted plate wearing and tearing, affects the result of use of neoprene bearing; And rubber bodies poor stability, easily oxidized, application life is short, needs to change in time bearing, waste time and energy, and maintenance cost is high; At the active force that the multiple stage of earthquake suffers horizontal and vertical direction for a long time, rotation is poor, and after shake, recovery capability is poor, causes the easy fatigue aging of rubber bodies; Installing when bridge, easily there is skew in rubber bodies, and rubber bodies discontinuity is used for a long time, and the easy fatigue aging of rubber bodies affects application life of rubber bodies.
Utility model content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of anti-oxidant, the neoprene bearing of long service life.
Realize above-mentioned purpose, the utility model is by the following technical solutions: a kind of neoprene bearing, comprise rubber bodies, be located at the upper fixed seat of rubber bodies upper end and be located at the lower fixed seat of rubber bodies lower end, between described rubber bodies and lower fixed seat, be provided with polyfluortetraethylene plate, rubber bodies soffit is provided with the protuberance of circular arc, and polyfluortetraethylene plate upper surface is provided with the recess corresponding with protuberance; Fixed seat top is provided with upper junction plate, and lower fixed seat below is provided with the upwards lower connecting plate of extension of two ends band, between lower connecting plate and lower fixed seat, is provided with movable plate, between the upwards extension at lower fixed seat two ends and lower connecting plate, is provided with damped ring; The surface of described rubber bodies is provided with topping; In described rubber bodies, be provided with polyamide fibre epithelium layer of cloth.
As preferably, described lower fixed seat two ends are provided with upwardly extending the second extension, and described polyfluortetraethylene plate is located between second extension at lower fixed seat two ends.
As preferably, described upper junction plate comprises a horizontal long slab and is located at longitudinal short slab at horizontal long slab two ends.
In sum, the utlity model has following advantage: damped ring enhanced leaktightness effect is set, avoids piling up dust and other impurities on movable plate, cause junction plate and upper mounted plate wearing and tearing, affect the result of use of neoprene bearing; The neoprene bearing shock resistance of this setting is strong, and described rubber bodies bottom arranges recess, multi-directionally flexible rotating, and after shake, recovery capability is strong, when bridge is installed, there will not be skew, and tetrafluoroethene plate is stressed evenly, not fragile, easily manufactured; Described lower connecting plate two ends are provided with upwards extension, and it is more firm that this setting is installed rubber bodies, strengthened stability; This topping is set and prevents that rubber bodies is oxidized, effect is lasting, has extended the application life of neoprene bearing, and topping can repeatedly apply, and strengthens the oxidation proof properties of rubber bodies.
