Abstract

The invention discloses an anti-overturning reinforcing and supporting device of a single-column pier girder bridge. According to the anti-overturning reinforcing and supporting device of the single-column pier girder bridge, one side of a pier (2) is provided with a pier bearing steel plate (4) in the transverse direction of the bridge, the bottom of a girder (1) on the same side is provided with a girder arc bearing steel plate (9), an H-shaped steel supporting structure (7) is hinged to the pier bearing steel plate (4) through a hinge steel plate (5), hinge balls (8) are hinged to the H-shaped steel supporting structure (7) and embedded into the girder arc bearing steel plate (9), the hinge balls (8) and the girder arc bearing steel plate (9) are in sliding / rolling contact, and thus a steel structure supporting system for connecting one side of the pier (2) in the transverse direction of the bridge with a bottom plate of the girder (1) on the same side is formed; the same reinforcing and supporting structure is established on the other side symmetrical to the pier (2), finally a single-point supporting system of the single-column pier girder bridge is reinforced and supplemented, a three-fulcrum multi-point supporting system including an original supporting seat is formed, and the purpose of anti-overturning reinforcing of the single-column pier girder bridge is achieved.

Description

technical field

[0001] The invention relates to an anti-overturning reinforcing support device for a single-column pier beam bridge. Specifically, by setting hinged I-beams between the pier and the main girder, the auxiliary support system of the main girder is added in addition to the single fulcrum of the original single-column pier, and the sliding between the main girder arc supporting steel plate and the hinged sphere is adopted. / Rolling to meet the needs of the longitudinal displacement of the main girder during the operation phase, thus forming a single-column pier girder bridge anti-overturning reinforcement support device. The anti-overturning reinforcing support device for a single-pillar pier beam bridge is suitable for structural reinforcement by adding a support system to a single-pillar pier beam bridge that already has a hidden danger of overturning, thereby preventing catastrophic collapse of the bridge and avoiding casualties.
