Description

Technical Field

[0001] The utility model relates to the technical field of bridge supports, in particular to a one-way sliding ball-shaped steel support. Background Art

[0002] Spherical steel bearings are an indispensable engineering part in the design and construction of contemporary bridges. Bridge bearings are important structural components that connect the superstructure and substructure of bridges. They are devices that are erected on piers and support the superstructure of bridges on the top surface. Their function is to fix the superstructure to the piers, bear various forces acting on the superstructure, and reliably transmit them to the piers; under the action of load, temperature, concrete shrinkage and creep, the bearings can adapt to the rotation angle and displacement of the superstructure, so that the superstructure can be deformed freely without generating additional internal forces. Spherical bearings refer to a new type of bridge bearing developed on the basis of pot-type rubber bearings. Their rotation performance in all directions is consistent, which can adapt to the needs of large rotation angles and reliable force transmission. They not only have the characteristics of strong bearing capacity and large horizontal displacement of pot-type rubber bearings, but also can adapt to the needs of large rotation angles, and are suitable for wide bridges, slope bridges, curved bridges, etc.; and because the pressure-bearing parts do not use rubber blocks, there is no influence of rubber low-temperature brittleness, so they are particularly suitable for low-temperature areas.

[0003] Today's transmission spherical bearings can only rotate, cannot move or can only move a short distance, which cannot meet the needs of some special bridges. At the same time, the stress state of the steel bearing base and the steel bearing top is relatively complex and cannot slide in one direction better. Utility Model Content
