Description
Technical Field

Background
The main function of the support is to reliably transmit the counterforce of the upper pier to the lower pier and simultaneously complete the deformation requirements required by the bridge structure, and in order to meet the requirements, the support needs to have enough rigidity in the vertical direction, so that the support can only generate small deformation under the maximum vertical load.
Because the internal structure of the spherical support adopts a metal part as a pressure bearing structure, and particularly adopts the friction between the metal spherical crown lining plate and the curved surface polytetrafluoroethylene plate to realize the rotation, the anti-corrosion of the metal spherical crown lining plate and parts inside the spherical support is very important. Particularly, in the pressure bearing process of the spherical support, silicone grease which is pre-stored in the assembly process can be gradually extruded, so that the metal spherical crown lining plate on the contact surface of the spherical support and the polytetrafluoroethylene plate has no anti-rust measure. The rust-resistant measure that current ball-type support adopted usually is to paint rust-resistant treatment to outside steel spare, but lies in the inside steel spare of ball-type support basin type (including metal spherical crown welt) and can not provide effectual rust-resistant measure yet, and in ball-type support maintenance process, whether inside corrosion appears is also be convenient for arrange in addition. More importantly: once the inside of the spherical support is rusted, the rust can greatly influence the friction coefficient of a polytetrafluoroethylene plate inside the spherical support and seriously influence the service life of the spherical support; therefore, the market needs to seek a technical scheme for solving the rust prevention problem of the spherical support adopting the pressure-bearing metal piece inside.
In addition, the steel plate base internal structural member of the spherical support rotates by adopting the pressure bearing principle of a metal part and particularly adopting the friction between the bottom of the metal spherical crown lining plate and the curved polytetrafluoroethylene plate. Because the spherical support only bears pressure at the bottom through rotation, the existing spherical support has poor performance on bearing performance when being applied to engineering application of wide bridges, curve bridges, ramp bridges, inclined bridges and large-span bridges.
