Technical Field

[0001] The invention relates to the technical field of bridge bearings, and in particular to a bridge bearing capable of monitoring deformation in real time. Background Art

[0002] Bridge bearings are important components of bridges, and they play a connecting role in the process of bridge load transfer. During the construction of bridges, it is often necessary to measure the top surface of each bearing to ensure that the bearing remains horizontal after installation. For example, in a bridge bearing with a real-time horizontality monitoring function as shown in Chinese patent application number CN202121820604.2, the top plate is installed on the bottom basin through an arc-shaped connection structure, and a number of monitoring structures for measuring horizontality at all times are also installed on the top plate; the monitoring structure is installed at the bottom of the top plate near the side, and the monitoring structure is fixed in a notch opened at the bottom of the top plate by screws.

[0003] However, when using the monitoring structure to intuitively determine the rotation state of the bearing and thus the state of the bridge, since the monitoring structure is installed on the top plate, the monitoring structure cannot be stored, which may easily cause the monitoring structure to stand upright and expose the outside of the top plate when the bridge bearing is not in use, thereby causing the monitoring structure to be damaged by external forces. Summary of the invention

[0004] In order to solve the problem raised in the above background technology that the monitoring structure is installed on the top plate and cannot be stored, which easily causes the monitoring structure to stand upright and expose the outside of the top plate when the bridge bearing is not in use, thereby causing the monitoring structure to be damaged under external forces, the present invention provides the following technical solutions: A bridge bearing capable of real-time monitoring of deformation comprises a bridge pier, wherein the bridge pier comprises a bridge bearing body arranged on the top of the pier, wherein a monitoring device for monitoring the bridge is arranged in the bridge bearing body, and wherein a storage device for folding and storing the monitoring device is arranged in the bridge bearing body.
