[0003] The sealing rubber belt of the current bridge expansion joint device is easy to fall off, and it is difficult to reinstall it. In addition, once the local section steel is deformed or broken, the concrete at the expansion joint notch at the end of the bridge beam body must be chiseled out. The entire maintenance process is costly and requires prolonged traffic interruption
Moreover, the length of the expansion joint profile steel is the same as the width of the bridge deck. When transporting, the profile steel on both sides of the expansion joint needs to be temporarily fixed according to the expansion joint width, and then the expansion joint is transported to the construction site by a special vehicle for installation. It is not easy to transport and the installation is more complicated.

The invention relates to the field of bridge buildings, in particular to a detachable buckling and pressing type sealing rubber belt bridge expansion device which comprises an expansion joint reserved notch. A profile steel base and detachable profile steel are arranged in the reserved notch. Lock nuts and bolts capable of closely anchoring the profile steel base and the detachable profile steel together are arranged in the reserved notch. Rubber pads are arranged between the profile steel base and the detachable profile steel. Bolt holes are formed in the profile steel base. A bolt closing box is arranged under the profile steel base. The profile steel base is provided with grooves and protrusions. Bolt holes are formed in the detachable profile steel. Sealing rubber belt buckling and pressing slots are formed in the lower portion of one end, close to an expansion joint, of the detachable profile steel. Protrusions are arranged at the two ends of a sealing rubber belt and can be closely buckled and pressed under the buckling and pressing slots of the detachable profile steel. The device further comprises an automatic monitoring and detecting system. The device has the advantages that the sealing rubber belt is directly buckled, pressed and installed and never falls off; after an alarm is given automatically, the sealing rubber belt can be disassembled directly so that the damaged expansion joint structure can be maintained in time, the installing time is short, replacing is convenient, and complete interruption of traffic is not needed.
Description
technical field [0001] The invention relates to the field of bridge construction, in particular to a detachable buckle-type sealing rubber belt bridge telescopic device. Background technique [0002] The defective of prior art is: [0003] The sealing rubber belt of the current bridge expansion joint device is easy to fall off, and it is difficult to reinstall it. In addition, once the local section steel is deformed or broken, the concrete at the expansion joint notch at the end of the bridge beam body must be chiseled out. The entire maintenance process is costly and requires Prolonged interruption of traffic. Moreover, the length of the expansion joint section steel is the same as the width of the bridge deck. During transportation, the section steel on both sides of the expansion joint needs to be temporarily fixed according to the expansion joint width, and then the expansion joint is transported to the construction site for installation by a special vehicle, which is ...
