Problems solved by technology

[0004] For example, the Chinese patent document CN103510464A adopts a double spherical structure. In the case of a double spherical surface, there are three friction structures in the vertical direction. The stability will be reduced, and when there are many friction structures, the bridge bearings are relatively easy to overturn
[0005] Chinese patent document CN101705722A discloses a hyperboloid shock-absorbing tensile support, which has multiple spherical friction structures. In order to ensure the stability of multiple spherical friction structures, it is equipped with components with tensile functions, which can Pressing on the uppermost spherical surface can make the stability of the support better, but its individual height, and the structure for maintaining stability is more complicated

Embodiment Construction

[0027] Bridge supports generally have an up-and-down structure, wherein the upper support plate 4 and the lower support plate 1 can be considered as two seat plates, wherein the upper support plate 4 is generally fixed to the girder body of a bridge by bolts 11 of the upper support plate Connection, the lower bearing plate 1 is generally fixedly connected with, for example, a bridge pier through the lower bearing plate bolts 2 . A friction structure is generally constructed between the upper support plate 4 and the lower support plate 1 to provide a moving or rotating function.

[0028] It is known that if the connection between the beam body and the pier column is only a fixed connection, the connection stability is relatively good, but the response ability to the deformation of the beam body or to vibration is relatively poor. How to use sliding parts for connection can correspond to the deformation of the beam body or the response ability of vibration is relatively strong, ...

Abstract

The invention discloses a bridge support which comprises a lower support plate, a steel liner plate and an upper support plate. A protruding part is arranged in the middle of a lower spherical surface. A first spherical crown protruding upwards is arranged at the top end of the protruding part, the steel liner plate is a second spherical crown with the upper surface being a cut plane, a central blind hole is formed in the middle of the crown part of the second spherical crown, the hole type of the central blind hole is a spherical hole and the central blind hole is provided with an upper spherical surface. The spherical surface of the crown part of the second spherical crown is matched with the lower spherical surface to form a first spherical surface friction structure. The upper spherical surface is matched with the first spherical crown to form a second spherical surface friction structure. The lower surface of the upper support plate is matched with the cut plane. The bridge support is strong in slipping capacity and high in stability.

Description

technical field [0001] The invention relates to a bridge support. Background technique [0002] At this stage, there are mainly three types of bridge bearings commonly used in the market, namely plate rubber bearings, pot rubber bearings, and spherical bearings. Among them, the basin-type rubber bearing realizes the horizontal displacement of the bearing through the plane slide plate, and uses the elastic deformation of the rubber to realize the micro-rotation of the bearing; the ball-type bearing is developed on the basis of the basin-type rubber bearing, which is different from the basin The difference between the type rubber bearing is that the spherical bearing realizes the rotation of the bearing through the sliding of the spherical sliding plate on the spherical crown liner. [0003] At the outer piers of wide bridges or in some special working conditions, the bearings are required to have greater rotational performance and sliding capacity in a certain direction. Ge...
