System for active prevent concrete beam falling phenomenon and application method thereof

Abstract

The invention discloses a system for active prevent a concrete beam falling phenomenon and an application method thereof. The system involves a concrete beam main beam, wherein a blocking block A anda blocking block B are arranged on the two sides of a cover beam below the concrete beam main beam, the two blocking blocks are embedded with an electromagnet A and an electromagnet B respectively, anelectromagnet C and an electromagnet D are embedded in the positions, attached to the blocking block A and the blocking block B, of the concrete beam main beam respectively, a displacement monitoringdevice A and a displacement monitoring device B are arranged on the electromagnet A and the electromagnet B respectively, the system further comprises a single-chip microcomputer circuit system, allthe electromagnets and the displacement monitoring devices are connected with the single-chip microcomputer circuit system, the single-chip microcomputer circuit system is connected with the electromagnet A, the electromagnet B, the electromagnet C and the electromagnet D to from a circuit, according to the monitoring result of the displacement monitoring devices, the current in the circuit changes the size and orientation, the intensity of the electromagnets is controlled through the size of the current, attraction or repulsion between the electromagnets is controlled through the current direction, so that close fit and separation between the concrete beam main beam with the blocking block A and the blocking block B are realized, bridge falling is prevented, and normal and ordered use ofa bridge is guaranteed.

Description

technical field [0001] The invention belongs to the field of transportation engineering and bridge technology processing, and in particular relates to a system for actively preventing concrete beams from falling and a method for using the same. Background technique [0002] Under the action of earthquakes, explosions and impact loads, the bridge structure often undergoes large vibrations. In severe cases, it may cause the upper concrete beam body to have a lateral displacement exceeding the limit, the block to be damaged, and the beam body to fall. As a hub project on the traffic line, once the concrete beam falls, the traffic network will be paralyzed, which will bring great difficulties to the post-disaster rescue work and seriously affect the lives of the people. [0003] In the existing technical field of bridge engineering, more and more researchers are paying attention to the phenomenon of preventing bridge beams from falling.

As a hub project on the traffic line, once the concrete beam falls, the traffic network will be paralyzed, which will bring great difficulties to the post-disaster rescue work and seriously affect the lives of the people.

[0003] In the existing technical field of bridge engineering, more and more researchers are paying attention to the phenomenon of preventing bridge beams from falling. The girder is set in a multi-layer structure, which can limit the longitudinal displacement of the box girder. At the same time, there are three layers of transverse energy dissipation devices in each layer of the box girder, which can limit the lateral displacement of the box girder. However, this method is based on the main body of the bridge. Starting with the structure, the structure is complex, the economic cost is high, and it costs a lot; another example is the patent document with the publication number CN208440969U, which discloses a T-shaped cross-section beam bridge anti-seismic and anti-fall beam structure, which includes a cover beam and a cover beam The steel plate placed horizontally above, the horizontal steel plate is anchored on the cover beam through the anchor bolt embedded in the cover beam, two vertical steel plates are vertically arranged on the flat steel plate, and two rows of threaded steel bars are arranged between the two vertical steel plates. It can limit the longitudinal and lateral displacement of T-beams and avoid the hazards of T-beams falling in earthquakes. Although this method is simple in structure, once the bridge structure is completed, it cannot be changed and is not flexible enough. With the increase of the service life of the bridge, it will continue to wear out. , users cannot effectively monitor the bridge, which is far from the development direction of artificial intelligence in the new era
