Abstract
A shear-resistant and torsion-resistant stiffness-variable pot rubber bearing is characterized by consisting of an upper bearing plate, a rubber plate and a lower bearing plate. The rubber plate is arranged between the upper bearing plate and the lower bearing plate, an upper limiting plate is fixed on the periphery of the upper bearing plate, a lower limiting plate is fixed on the periphery of the lower bearing plate, and an alloy steel plate is disposed in the rubber plate and provided with a plurality of holes. The shear-resistant and torsion-resistant stiffness-variable pot rubber bearing has the advantages of capabilities of saving materials and meeting requirements of stiffness of bridges, simple structure, simplicity in procedure, low processing cost and fine fixing effect, accordingly is high in operability, and is suitable to be widely popularized and used.
Description
Technical field
The utility model relates to bridge pad, specifically is a kind of anti-shearing, torsion proof change rigidity pot rubber bearing.
Background technology
The operating principle of pot rubber bearing is to utilize to be closed in the Intrapelvic elastic rubber slab of steel; The characteristics that under triaxial stress state, have the volume Incoercibility of fluid; The counter-force of bridge superstructure is delivered on the pier reliably, and realizes the rotation of bridge beam-ends; The horizontal movement that polyfluortetraethylene plate in the middle of relying on simultaneously on the steel liner plate and the low-friction coefficient between the corrosion resistant plate on the bearing top board are realized superstructure; The suffered shear stress of bearing is no longer undertaken the whole thing by rubber tile; And indirectly-acting is in the slippage between base-plate and polyfluortetraethylene plate and the corrosion resistant plate, thereby guarantees the safe in utilization of bridge.So pot rubber bearing can satisfy big bearing reaction, big horizontal movement, and big corner requirement.Not enough below but these bearings exist: as 1, to be prone to produce lateral restriction, 2, construction requirement is high: both sides guide type bearing when mounted, guide pad must guarantee parallelly up and down, the angle of the crossing must not be greater than 5 °, otherwise are prone to when sliding stuckly, it is flexible to hinder the beam body; 3, upper plate use cast steel manufacturing so own wt are very heavy.
The utility model content
The purpose of the utility model is the deficiency that overcomes above-mentioned existence, provides a kind of property simple in structure, easy to use, safe good, rotates anti-shearing flexibly, torsion proof change rigidity pot rubber bearing.
The technical scheme that the utility model is adopted to achieve these goals is: a kind of anti-shearing, torsion proof change rigidity pot rubber bearing; It comprises upper bracket plate, polytetrafluoroethylene (PTFE) slide plate, middle steel plate, rubber tile, lower support plate and guide pad; It is characterized in that said polytetrafluoroethylene (PTFE) slide plate is arranged between upper bracket plate and the middle steel plate; Middle steel plate and rubber tile are positioned at lower support plate, also are provided with sealing ring between said middle steel plate and the rubber tile, and said guide pad is arranged on the center of polytetrafluoroethylene (PTFE) slide plate and middle steel plate and passes through bolt; Be provided with alloy-steel plate in the said rubber tile, this alloy-steel plate is provided with some holes.
Anti-shearing, torsion proof according to described in the utility model become the rigidity pot rubber bearing, it is characterized in that said guide pad center is provided with bolt hole.
Become the rigidity pot rubber bearing according to anti-shearing, the torsion proof described in the utility model, it is characterized in that being connected through bolt between said upper bracket plate and the lower support plate.
Anti-shearing, torsion proof according to described in the utility model become the rigidity pot rubber bearing, it is characterized in that said alloy-steel plate is more than one and spacing is arranged on rubber tile inside uniformly.
Become the rigidity pot rubber bearing according to anti-shearing, the torsion proof described in the utility model, it is characterized in that the hole on said adjacent two alloy-steel plates is dislocatedly distributed.
The utility model is a kind of anti-shearing, torsion proof change rigidity pot rubber bearing; This bearing has solved the restriction of existing bearing intersecting angle, and when having overcome installation, guide pad must guarantee technical problems such as parallel up and down; Alloy-steel plate evenly is set in rubber tile simultaneously; Thereby therefore can change the rigidity of the rigidity change bearing of rubber tile according to the practice of construction demand, satisfy the bridge demand, some holes are set on alloy-steel plate simultaneously; Therefore make to contact more firmly between alloy-steel plate and the rubber tile, increased the shearing resistance degree and the torsional rotation force degree of bearing.Advantages such as therefore to have property simple in structure, easy to use, safe good for this bearing, and shear resistance, antitorque commentaries on classics property are strong are fit to be widely used.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-upper bracket plate, 2-polytetrafluoroethylene (PTFE) slide plate, 3-bolt, 4-middle steel plate, 5-sealing ring, 6-rubber tile, 7-lower support plate, 8-guide pad, 9-alloy-steel plate, 10-hole.
The specific embodiment
To combine accompanying drawing that the technical scheme of the utility model is done below further describes:
As shown in Figure 1: a kind of anti-shearing, torsion proof change rigidity pot rubber bearing; It comprises upper bracket plate 1, polytetrafluoroethylene (PTFE) slide plate 2, middle steel plate 4, rubber tile 6, lower support plate 7 and guide pad 8; It is characterized in that said polytetrafluoroethylene (PTFE) slide plate 2 is arranged between upper bracket plate 1 and the middle steel plate 4; Middle steel plate 4 is positioned at lower support plate 7 with rubber tile 6; Also be provided with sealing ring 5 between said middle steel plate 4 and the rubber tile 6, said guide pad 8 is arranged on the center of polytetrafluoroethylene (PTFE) slide plate 2 and middle steel plate 4 and passes through bolt.Said guide pad 8 centers are provided with bolt hole.Be connected through bolt 3 between said upper bracket plate 1 and the lower support plate 7.Wherein rubber tile 6 inside evenly are provided with the alloy-steel plate 9 more than; The number of alloy-steel plate can confirm according to the demand of practice of construction, thereby satisfies the requirement of bridge, and secondly several holes 10 is set on alloy-steel plate 9; And the hole 10 on the adjacent alloy-steel plate 9 is dislocatedly distributed; Thereby make closely to contact between alloy-steel plate and the rubber tile 6, increase the dynamics that is connected firmly between the two, thereby increased anti-shearing, the torsional rotation force degree of bearing.
