Description

Technical Field

[0001] The invention belongs to the technical field of bridges and relates to a shock-absorbing bearing for a road bridge with a reminder function and a construction method thereof. Background Art

[0002] Bridges generally refer to structures erected over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are erected to cross mountain streams, poor geology, or meet other transportation needs to make travel more convenient. Bridges are generally composed of superstructures, substructures, supports, and ancillary structures. The superstructure, also known as the span structure, is the main structure for crossing obstacles; the substructure includes abutments, piers, and foundations; the supports are force transmission devices installed at the supporting locations of the span structure and piers or abutments; and the ancillary structures refer to the bridgehead slabs, conical slope protection, revetments, diversion projects, etc.

[0003] The base of the rail bridge needs to be installed with a buffer device to protect the bridge. However, the existing buffer device has insufficient supporting capacity and a single function. Most of them are primary buffers. When the bridge is subjected to pressure exceeding the device's tolerance range or a large vibration, the bridge is prone to tilt. In extreme cases, the bridge may collapse, with disastrous consequences. In addition, in extreme cases, it is impossible to remind passing vehicles. Therefore, we propose a shock-absorbing bearing for road bridges with a reminder function and a construction method thereof to solve the above-mentioned problems. Summary of the invention

[0021] S5. When the vibration exceeds the bearing range of the bridge, the upper mounting plate drives the first push rod to move vertically downward, the first push rod drives the sliding plate to move vertically downward, the sliding plate squeezes the second spring and presses the travel switch, the travel switch causes the sound and light alarm to sound an alarm to remind passing vehicles and improve safety, the sliding plate releases contact with the support block, the support block moves laterally under the elastic force of the first spring, the support block drives the support rod to move laterally, the support rod moves to the bottom of the upper mounting plate to protect the bridge and the device and extend the service life of the device.
