Description
Technical Field
The utility model relates to the field of civil construction engineering, in particular to a steel bridge stop block for an arc section.
Background
Along with urban modernization and aesthetic improvement of people, the requirements of viaduct landscapes are increasing. As a stop block for bridge anti-seismic construction measures, the anti-seismic bridge anti-seismic structure has wide application and various forms. Urban space restriction and view requirement, the pier becomes light and handy, succinct, often does not have sufficient position on the resulting pier, sets up reinforced concrete dog, adopts the pier side to add the mode that the steel chosen the arm and set up the dog, because space occupation is many, the view nature is relatively poor, is difficult to obtain promoting in urban construction.
The bridge with the arc-shaped section has good landscape design and is popular in the construction of viaducts. The support needs to be arranged in an arc change section, and is more convex in a steel structure ramp bridge with a small curve radius.
At present, a stop block is arranged at the bottom of a steel structure beam, a vertical steel plate of the stop block is directly welded with a steel beam bottom plate, a corresponding stiffening plate is arranged in the steel beam bottom plate, and in site construction, the position of a stiffening rib of the stop block in the steel beam bottom plate is difficult to correspond to the position of the vertical steel plate of the stop block, so that the problem of tearing and damaging the steel structure beam bottom plate occurs; in addition, the steel stop block has relatively small rigidity and large deformation.
Disclosure of Invention
The utility model aims to provide a steel bridge stop block for an arc-shaped section, which overcomes the defects of the stop block in the prior art.
In order to achieve the above object, the technical scheme of the present utility model is as follows:
a steel bridge stop block for an arc section comprises a stop block vertical steel plate, a bowl-shaped steel plate, a stop block bottom steel plate, a steel beam bottom plate and a steel structure beam bottom stiffening steel plate; the curvature of the bowl-shaped steel plate is consistent with that of the steel beam bottom plate, and the bowl-shaped steel plate and the steel beam bottom plate are welded together through side welding and plug welding; and the vertical steel plate of the stop block corresponds to the stiffening steel plate at the bottom of the steel structure beam.
Further, the vertical steel plate of the stop block and the bowl-shaped steel plate are welded to form a closed small box chamber.
Further, shear nails are welded on the vertical steel plates of the stop blocks and the steel plates at the bottoms of the stop blocks.
Further, a tank concrete hole is formed in the vertical steel plate of the stop block, and concrete is filled in the closed small tank chamber.
Further, the vertical steel plates of the stop blocks can be stuck with rubber stop blocks on corresponding vertical surfaces according to the requirements of the anti-seismic anti-falling beams.
Further, the concrete is micro-expansive concrete.
Compared with the prior art, the utility model has the following beneficial effects:
1. because arc steel sheet and girder steel arc bottom plate pass through the side welding together, the dog stiffening plate position is not corresponding in effectively having solved the vertical steel sheet of dog and the steel bottom plate, appears girder steel bottom plate and tear the damage problem, and has improved the construction progress.
2. Compared with a reinforced concrete stop block, the stop block has high shear strength; compared with the existing steel stop block, the steel concrete stop block has high shear strength, good overall rigidity and small deformation.
3. The vertical steel plate is adhered with the rubber stop block, so that the rubber stop block is high in applicability, and the stop block can be blocked on the side face of the pier, and a certain gap is reserved between the stop block and the pier; the device can also be blocked on the side surface of the support lower bolster and keep a certain gap with the support lower bolster; and the bridge pier can also extend into an inner groove preset at the top of the bridge pier, and a certain gap is reserved between the bridge pier and the fixed inner groove wall and the inner groove bottom of the bridge pier.
4. Under the prerequisite that satisfies shock resistance, this patent dog can make the volume less, and view nature is good.
