Description

Support for bridge

Technical Field

With the high-speed growth of the economy of China, the traffic cause of China also obtains great improvement and progress. With the rapid spread of highways and expressways, the loss of bridges in some roads is also increasing. In the long-term use process of the bridge, the use performance and the safety of the structure are damaged to different degrees under the adverse working conditions of overload, overload operation and the like, and in order to judge whether the bridge structure is in a normal use state, health monitoring and early warning of the operation state of the bridge are realized, and a set of effective safety monitoring structure system needs to be arranged.

The support is an important structural component for connecting the upper and lower structures of the bridge, and can reliably transfer the counter force and deformation (displacement and corner) of the upper structure of the bridge to the lower structure of the bridge, so that the actual stress condition of the structure conforms to the calculated theoretical diagram. However, the traditional support does not have a force measuring function, and does not have the function of adjusting the height of a bridge due to construction errors and height difference of the bridge generated during use, so that the stress of each support is adjusted. In order to ensure the detection and analysis of the stress condition, a part of the supports are provided with special sensors, for example, the Chinese utility model patent with the patent number CN201220553496.1 discloses a hinged steel support with a force sensor and a curved steel support with a force sensor, the support is positioned with a horizontal force sensor with a horizontal prestress compensator at the tail end on a support top plate, the head end of the horizontal force sensor is propped against a support bottom plate, when the steel support generates poisson deformation or other deformations, the horizontal force sensor can simultaneously measure the force values generated by the interference deformations, and in the later data processing, the measured interference values can be eliminated through simple mathematical operation, thereby eliminating the influence of the interference force on the force measurement result, and improving the force measurement accuracy and authenticity.

Although the above-described sensors are capable of detecting horizontal forces, the forces experienced by the bearers are complex during use of the bridge, particularly in the turning sections of the bridge. Therefore, if the detection of the bridge support is only stopped at the traditional horizontal force detection and vertical force detection, careless leakage is easily caused, and potential safety hazards are caused.
