Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 — Figure 11 As shown, the parallel single-column pier bridge non-contact connection reinforcement device provided by the present invention is arranged between two parallel single-column box girders 1, including footing reinforcement bolts 2, steel plates 4, support beams 5, diagonal braces 6, Cylindrical pins 10, conical pins 11 and cotter pins 12; wherein, the support beam 5 is an inverted L-shaped I-shaped steel bar composed of vertical bars and horizontal bars, and the vertical bars on the multiple support beams 5 are spaced apart by foot reinforcement bolts 2 The distance is fixed in parallel on the pier of each single-column box girder 1 close to the inner surface of another single-column box girder 1, and the horizontal bar located under the flange of the single-column box girder 1 extends to the direction of t...

Abstract

The invention relates to a non-contact connection reinforcing device for a parallel single-column pier bridge. The non-contact connection reinforcing device for the parallel single-column pier bridgeis arranged between two parallel single-column box girders and comprises footing reinforcement bolts, steel plates, support beams, diagonal braces, cylindrical pins, conical pins and split pins. According to the invention, the non-contact connection reinforcing device for the parallel single-column pier bridge has the following beneficial effects: when one side of the parallel single-column pier bridge overturns, the overturning of this side can be can be restrained by the parallel single-column pier bridge at the other side in a non-contact connection mode, so that the problem of lateral overturning stability of the parallel single-column pier bridge is effectively solved, and the parallel single-column pier bridge has definite stress, simple structure, no influence on the space under thebridge and the beautiful appearance of the bridge, and is beneficial to popularization and use in the anti-overturning reinforcement engineering of the parallel single-column pier bridge.

Description

technical field [0001] The invention belongs to the technical field of reinforcement of single-column pier bridges, in particular to a non-contact connection reinforcement device for parallel single-column bridges. Background technique [0002] With the rapid development of transportation, China has built a large number of bridges, especially the rapid development of expressways and urban viaducts, so bridges have become the throat of transportation. However, due to the common situation of overloading, individual overloading even reaches 200% to 300%, so it is very unfavorable to the stability of the lateral overturning structure, and accidents caused by it are not uncommon. [0003] For a single-pillar bridge supported laterally by a single pier, because it uses a single fulcrum for support, if the vehicle cannot travel along the centerline of the bridge, especially, when the vehicle is in an overloaded state, the structural components in the bridge are very The force may ...
