Description
Technical Field
The utility model relates to a public road bridge roof beam engineering field, concretely relates to earthquake-resistant structure based on pier is restoreed.
Background
Most of the bridges in service need to bear various acting forces, such as external forces of earthquake, unbalance loading, vehicle and ship collision and the like. The failure modes of the bridge pier under the action of earthquake mainly include shear failure, bending shear failure and bending failure. Once the foundation is damaged, the consequences are very serious, and the later repair and reinforcement become very difficult, so that it is necessary to perform targeted repair and reinforcement on the bridge and perform related research and development to alleviate the problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome not enough among the prior art, provide an antidetonation structure based on pier is restoreed.
The technical scheme of the utility model is that: an anti-seismic structure based on pier repair comprises a base station arranged at the bottom, wherein piers are symmetrically and fixedly assembled at the left end and the right end of the top of the base station, a supporting beam is fixedly assembled at the top of each pier, a cover beam is assembled at the top of the supporting beam, an upper main beam is fixedly assembled at the top end of the cover beam, pier top stop blocks extending upwards are arranged at two sides of the upper main beam of the cover beam, and a rubber base plate is arranged between the pier top stop blocks and the upper main beam; a plurality of carbon fiber cloth are uniformly distributed on the bridge pier, and each carbon fiber cloth is annularly wrapped and fixed on the outer wall of the bridge pier.
According to the further technical scheme, a buffer plate is arranged between the base station and the pier, and the buffer plate is fixed in the base station in an embedded mode.
According to the further technical scheme, the supporting beam is fixedly buckled on the pier.
The utility model has the advantages that: the utility model discloses utilize carbon cloth to have characteristics such as light weight high strength, corrosion-resistant, good elastic property, set up its bar ring package on the pier, carbon cloth's the vertical perpendicular to pier of tensile fibre this moment can provide great side direction constraining force to the pier, and oblique cracked production or further increase on the suppression pier avoid cuting destruction, the shock resistance of improvement pier that is showing. Meanwhile, the rubber base plate is additionally arranged between the stop block and the upper main beam, so that the earthquake energy can be consumed through the stop block and the rubber base plate under the action of rare earthquakes, and the aim of reducing the action of the earthquake force is fulfilled.
Drawings
FIG. 1 is a schematic structural view of the present invention,
the device comprises a base platform 1, a base platform 11, a buffer plate 2, a pier 3, a support beam 4, a cover beam 41, a pier top stop block 42, a rubber base plate 5, an upper main beam 6 and carbon fiber cloth.
Detailed Description
The invention will be further elucidated below by means of non-limiting examples, with the understanding that the invention is not limited thereto.
As shown in fig. 1, the utility model provides an antidetonation structure based on pier is restoreed, including setting up in the base station 1 of bottom, the both ends symmetry is fixed to be equipped with pier 2 about the top of base station 1, is provided with buffer board 11 between base station 1 and the pier 2, and buffer board 11 is embedded fixes in base station 1.
The top of each pier 2 is fixedly provided with a supporting beam 3, and the supporting beam 3 is fixedly buckled on the pier 2. The top of the support beam 3 is provided with a bent cap 4, the top end of the bent cap 4 is fixedly provided with an upper main beam 5, two sides of the bent cap 4, which are positioned on the upper main beam 5, are provided with pier top blocking blocks 41 extending upwards, and a rubber base plate 42 is arranged between the pier top blocking blocks 41 and the upper main beam 5; the utility model discloses an increase rubber tie plate 42 between dog and upper portion girder 5, under rare meeting earthquake effect, can consume seismic energy through dog and rubber tie plate 42, reach the purpose that reduces the earthquake effort.
A plurality of carbon fiber cloths 6 are uniformly distributed on the bridge pier 2, and each carbon fiber cloth 6 is annularly wrapped and fixed on the outer wall of the bridge pier 2. Because the carbon fiber cloth 6 has the characteristics of light weight, high strength, corrosion resistance, good elastic performance and the like, the strip-shaped ring is arranged on the pier 2 in a wrapping mode, at the moment, the tensile fibers of the carbon fiber cloth 6 are vertical to the pier 2, so that large lateral constraint force can be provided for the pier 2, the generation or further increase of oblique cracks on the pier 2 is inhibited, the shearing damage is avoided, and the shock resistance of the pier 2 is obviously improved.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
