Problems solved by technology

[0003] At present, the commonly used spherical bearings have low pull-out resistance, which makes the bearings less effective in resisting the upward pulling force of the beam body, and cannot effectively prevent the beam body from falling off caused by external factors such as earth

Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention:

[0022] like Figure 1 ~ Figure 4 As shown, a two-way sliding anti-pullout spherical bridge bearing, which includes a bearing top plate 1, a spherical crown lining plate 2, a middle bracket 3 and a lower bearing plate 4 that are sequentially slidably connected and matched from top to bottom. The support top plate 1 and the lower support plate 4 are respectively fixed to the beam body and the bridge pier by means of anchor bolts or welding; The connection part is provided with a first friction pair 6. Specifically, a mirror stainless steel plate with a thickness of not less than 3 mm is pasted on the lower surface of the support top plate 1, and a flat wear-resistant plate with a thickness of not less than 7 mm is embedded in the top surface of the spherical crown...

Abstract

The invention discloses a bi-directional sliding anti-pulling ball type bridge bearing, which comprises a support top plate, a ball crown liner, a middle bracket and a lower support plate which are slidably connected from top to bottom. A pull-out member is added between the top plate of the support and the middle bracket, and the upper end of the pull-up member is slidably connected to the planeof the top plate of the support, and a gap is retained between the pull-out member and the rectangular block I of the support top plate, and the pull-out member is retained. The lower end is rotatablyconnected with the upper end of the middle bracket, and the lower end of the middle bracket is slidably connected with the lower support plate plane, and the middle bracket and the lower bracket plate rectangular stopper II retain a certain gap. The design can realize the sliding of the bearing in the transverse direction and along the bridge direction, and the rotation of the bearing around themain and auxiliary directions, and the bearing has good anti-pulling ability, which is suitable for various bridges in special circumstances, and has the advantages of long service life, higher safety, strong economic practicability and high popularization.

Description

technical field [0001] The invention relates to a two-way sliding anti-pull spherical bridge bearing, which belongs to the field of bridge bearings for bridge construction. Background technique [0002] The anti-pull ball bearing is a new type of ball bearing suitable for high-intensity areas and areas with many hurricanes, which can be widely used. Used in bridges or building structures. The pullout support is arranged between the bottom of the beam and the top of the pier or at the bottom of the building. It supports the upper structure and has a vertical limit function. It can effectively resist the overturning and collapse of the upper structure caused by factors such as earthquakes or structural partial loads. Therefore, , which can ensure that the upper and lower structures of the bridge will not be disjointed under the action of vertical earthquake or structural partial load, which plays a very important role in the seismic performance of the bridge. [0003] At pre...
