Diamond-like film bionic support

Abstract

The invention discloses a diamond-like film bionic support. An arranged slide plate assembly comprises a rubber plate, a polytetrafluoroethylene plate and a slide plate; the lower surface of the polytetrafluoroethylene plate is provided with a protrusion corresponding to a first groove and a protruding head corresponding to a first round pit, and the lower surface of the polytetrafluoroethylene plate and the upper surface of the rubber plate are in alignment fit to form a bionic plate; the lower surface of the slide plate and the upper surface of the polytetrafluoroethylene plate form a first friction structure, and the upper surface of the slide plate cooperates with the lower surface of a support plate; the surface of a ball socket forms a diamond-like film which is used for being in sliding fit with a spherical crown lining plate. According to the diamond-like film bionic support, the friction coefficient of the main friction surface can be greatly lowered, and the service life of the spherical bridge support can be effectively prolonged.

Description

technical field [0001] The invention relates to a bridge support, in particular to a spherical bridge support. Background technique [0002] There are many types of bridge bearings, such as spherical bearings, plate rubber bearings, pot rubber bearings, etc. There are two main functions of bridge bearings. One is to effectively load the bridge load (dynamic load and static load) The second is to overcome the beam body bias caused by the displacement of the beam body due to braking force, ambient temperature, concrete shrinkage or creep, and load action. For example, in the lateral direction of the bridge body, if the side length of the beam body is long due to changes in the ambient temperature, while the distance between the pier columns remains unchanged, if the beam body and the pier columns are rigidly connected, the rigidly connected part may be It is sheared or the beam body generates a large shear force on the connecting part. The bridge supports make the beam body ...

Problems solved by technology

[0007] The Chinese patent document CN105064205A discloses a spherical bearing, and the 48th paragraph of its description points out that by setting a movable seat between the upper bearing and the lower bearing to realize the functional separation of the rotation and sliding of the spherical bearing, it can Avoiding the stuck stress concentration caused by the superposition of local functions of the support can overcome the problem of the harsh sliding environment when the friction environment is sliding friction to a certain extent, but because the configuration of the friction structure is still between the conventional PTFE plate and the ball socket The cooperation between them has a limited effect on the improvement of the friction environment
