Description

Technical Field

[0001] The utility model relates to the technical field of roads and bridges, and particularly relates to a bridge reinforcement device. Background Technique

[0002] A bridge generally refers to a structure erected over rivers, lakes and seas to enable vehicles, pedestrians, etc. to pass smoothly. To adapt to the modern rapidly developing transportation industry, a bridge is also extended to a building that is erected across mountain streams, poor geological conditions or to meet other traffic needs to make passage more convenient. A bridge generally consists of an upper structure, a lower structure, bearings and auxiliary structures. The upper structure is also called the bridge span structure and is the main structure for crossing obstacles; the lower structure includes abutments, piers and foundations; the bearings are force-transferring devices provided at the supporting points of the bridge span structure and the piers or abutments; the auxiliary structures refer to approach slabs, conical slopes, revetments, diversion works, etc.

[0003] In the bridge reinforcement device with the publication number CN214362950U, aiming at the problems that the existing bridge reinforcement device does not have a certain adjustment device, is inconvenient to install and fix, and is time-consuming and laborious to use, the following scheme is now proposed. It includes a bridge deck and a mounting plate. A pier is fixedly installed at the bottom of the bridge deck. A first fixing plate is slidably installed on one side of the mounting plate. One side of the first fixing plate is fixedly installed with one side of a first clamping plate. The other side of the first clamping plate is fixedly installed with a second fixing plate. A third fixing plate is fixedly installed on one side of the mounting plate. An adjusting device is movably installed on the third fixing plate and the first fixing plate. One side of a second clamping plate is movably installed on the third fixing plate. The utility model is convenient to use, does not need to always hold and fix during fixation, saves time and effort, and can adjust the distance between the two clamping plates according to the installation position, so that the fixing effect is good. However, the existing device still has deficiencies. The fixing mechanism of the existing device is insufficient, and it is easy to displace and become loose when fixing at the bottom of the bridge. And the adjusting mechanism of the existing device is insufficient, and it is inconvenient to adjust the support distance when supporting the bottom end. For this reason, we propose a bridge reinforcement device to solve the above problems. Content of the Utility Model
