Abstract
The utility model discloses a middle-oriented pot rubber support, which comprises an upper support plate, a polytetrafluoroethylene sliding plate, a middle steel plate, a rubber plate, a lower support plate and a guide block and is characterized in that the polytetrafluoroethylene sliding plate is arranged between the upper support plate and the middle steel plate; the middle steel plate and the rubber plate are positioned into the lower support plate; a seal ring is also arranged between the middle steel plate and the rubber plate; the guide block is arranged in the center of the polytetrafluoroethylene sliding plate and the middle steel plate and is fixed by a bolt. The utility model discloses the middle-oriented pot rubber bearing which overcomes the limit of an interleaved angle of an existing support, solves the technical problems that an upper guide block and a lower guide block have to ensure parallel and the like when the support is mounted. the middle-oriented pot rubber support has the advantages of simple structure, good safety and the like, is convenient in use and is applicable to being widely used.
Description
Technical field
The utility model relates to bridge pad, specifically is a kind of pot rubber bearing of middle guiding.
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.But these bearings have the following disadvantages: 1, easily produce lateral restriction, 2, the construction requirement height: 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 easily stuck when sliding, it is flexible to hinder the beam body; 3, employing cast steel manufacturing of upper bracket plate so own wt are very heavy.
The utility model content
The purpose of this utility model is the deficiency that overcomes above-mentioned existence, provides a kind of property simple in structure, easy to use, safe good, rotates the pot rubber bearing of middle guiding flexibly.
The technical scheme that the utility model is adopted to achieve these goals is: the pot rubber bearing of guiding in the middle of a kind of, 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 described 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 be provided with sealing ring between described middle steel plate and the rubber tile, described guide pad is arranged on the center of polytetrafluoroethylene (PTFE) slide plate and middle steel plate and passes through bolt.
Pot rubber bearing according to the middle guiding described in the utility model is characterized in that described guide pad center is provided with bolt hole.
Pot rubber bearing according to the middle guiding described in the utility model is characterized in that described guide pad is connected with middle steel plate by bolt.
According to the pot rubber bearing of the middle guiding described in the utility model, it is characterized in that described polytetrafluoroethylene (PTFE) slide plate is directed to piece and is divided into symmetrical two.
The utility model is a kind of pot rubber bearing of middle guiding, 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, have advantages such as property simple in structure, easy to use, safe is good, be fit to be extensive use of.
