Description

Technical Field

[0001] The utility model relates to the technical field of bridge supports, in particular to a bridge monitoring support. Background Art

[0002] The bridge bearing is an important structural component that connects the superstructure and substructure of the bridge and is located between the bridge and the pad stone. It can reliably transfer the load and deformation (displacement and rotation) borne by the superstructure of the bridge to the substructure of the bridge, and is an important force transmission device of the bridge. There are two types of bridge bearings: fixed bearings and movable bearings. Commonly used bearing forms in bridge engineering include asphalt felt or flat plate bearings, plate rubber bearings, spherical bearings, steel bearings and special bearings. These bearing types have their own characteristics and applicable scenarios. For example, the flat plate bearing is simple in structure and easy to process, but it is only suitable for beams with small spans; the steel bearing realizes the displacement and rotation function of the bearing through the rolling, shaking and sliding of the steel parts; the plate rubber bearing is rectangular and circular, suitable for different climatic conditions; the ball crown circular plate rubber bearing is superior to the ordinary flat circular rubber bearing under certain conditions.

[0003] The current force measuring bearing only measures vertical pressure. However, in actual operation, factors such as the displacement and deformation of the bearing also need to be considered. Therefore, it is necessary to propose a bridge monitoring bearing to meet the needs of actual use. Utility Model Content
