Description

Technical Field

[0001] The utility model relates to the technical field of bridge supports, in particular to a spherical transverse wind-resistant bridge support. Background Art

[0002] The spherical transverse wind-resistant bridge bearing is a bearing design used for bridge structures. This bearing is usually composed of a spherical pier and a spherical bearing. Its design is intended to enhance the stability and wind resistance of the bridge structure under transverse wind loads. Compared with traditional bridge bearings, the spherical transverse wind-resistant bridge bearing is more flexible in design and can better cope with the challenges of transverse wind loads. Its spherical design allows the bridge to respond more freely under the action of wind, reduces the force concentration of the bridge structure, and improves the overall stability and safety. The application of this bearing design in bridge engineering can effectively reduce the impact of transverse wind loads on the bridge structure, improve the wind resistance of the bridge, thereby extending the service life of the bridge and reducing the maintenance and repair costs of the bridge structure.

[0003] Patent document CN216551540U discloses a spherical wind-resistant bridge bearing, "including a bridge bearing body, the bridge bearing body is composed of an upper base and a lower base, the top corners of the upper base and the top corners of the lower base are connected by a spring-type telescopic rod, a buffer layer is installed at the middle position of the top of the lower base, a middle support is installed at the top of the buffer layer, and an arc groove is opened at the top of the middle support; by providing a guide hole and a guide groove, dust or gravel in the arc groove can flow into the guide groove through the guide hole, the overall design is reasonable, and can realize the cleaning and discharge of impurities in the arc groove, avoiding long-term accumulation of impurities in the arc groove to reduce the use effect of the first buffer spring."

[0004] However, the spherical wind-resistant bridge bearing disclosed in the above-mentioned public document does not take into account that most existing bridge bearings are usually installed with a single anchor bolt for fixing. When the bridge is displaced greatly by strong winds, the connection stability between the anchor bolt and the bridge is easily reduced. Therefore, it is necessary to develop a spherical transverse wind-resistant bridge bearing that can effectively solve the above-mentioned problems. Utility Model Content

[0007] Preferably, a wind-resistant support is provided at the bottom of the upper support plate, and the bottom of the wind-resistant support is connected to the lower support plate.

The threaded hole can be used to form a rotational adjustment effect for the screw, and the screw can be driven to rotate and move at the same time by rotating the hexagonal block. The screw will drive the circular plate and the anti-skid layer to move while the screw moves up and down. When the circular plate moves up, the anti-skid layer will contact the bridge to form a support. The anti-skid layer is used to improve the stability between the bridge and the support plate, and the support plate expands the support area and improves the stability. The technical problem that the connection stability between the anchor bolt and the bridge is easily reduced when the bridge is displaced greatly due to strong winds is solved.
