Abstract

The invention discloses a basin type rubber support which comprises a base, a rubber pad, a piston, a smooth wear-resisting plate, a polyfluortetraethylene plate and an upper seat plate. A cylindricalcavity is formed in the base, the rubber pad is arranged at the bottom of the cylindrical cavity, the piston is further arranged in the cylindrical cavity and located above the rubber pad and is in sealed connection with the inner wall of the cylindrical cavity, a sealed cavity is formed between the rubber pad and the piston, the upper surface of the piston is coated with the smooth wear-resisting plate, the polyfluortetraethylene plate is arranged on the lower bottom face of the upper seat plate, and the smooth wear-resisting plate and the polyfluortetraethylene plate are in sliding fit. Thesealed cavity is formed between the rubber pad and the piston and inflated and deflated through an inflation opening so that the air pressure of the sealed cavity can be changed, the effective supporting height of the whole support is adjusted, the support can be suitable for different occasions, the piston and the upper seat plate are in sliding fit through the spherical smooth wear-resisting plate and the polyfluortetraethylene plate, the upper seat plate has a large turning angle, and the requirement of the use condition for the large turning angle is met.

Description

【Technical field】 [0001] The invention relates to the technical field of bridge bearings, in particular to a pot-type rubber bearing. 【Background technique】 [0002] The bridge support is a device erected on the pier, and the top surface supports the upper structure of the bridge. Its function is to fix the superstructure to the abutment, withstand various forces acting on the superstructure, and transmit it reliably to the abutment; under the action of load, temperature, concrete shrinkage and creep, the support can adapt to the superstructure The rotation angle and displacement allow the upper structure to deform freely without generating additional additional internal force. Basin type rubber support is a kind of bridge support. It is a new type of bridge support composed of steel components and rubber. It has the advantages of large bearing capacity. [0003] At present, the height of the pot-type rubber bearings on the market is fixed after leaving the market, and the...
