Embodiment Construction

[0038] like Figure 1 to Figure 8 As shown, for existing defects, the subject of protection of the present invention is as follows:

[0039] In order to fundamentally solve the problem of overturning, the present invention starts from energy consumption to consume external loads such as wind loads of the point itself, and improve the performance indicators of the bridge itself such as earthquake resistance, wind resistance, and snow pressure resistance.

[0040] The support 9 is installed between the bridge pier 10 and the crossbeam 101, at least two are arranged, generally three are installed, refer to Figure 9 .

[0041] The following is a detailed introduction to the special support:

[0042] It includes a first board 1 , a second board 2 and a third board 3 arranged from top to bottom.

[0043] Wherein, the first board 1 adopts a steel plate with a thickness of at least 20 or 30 millimeters, and a first installation part 11 is arranged on the upper surface of the first...

Abstract

The invention discloses an anti-capsizing support of a bridge. The anti-capsizing support of the bridge comprises a first plate, a second plate and a third plate, wherein the first plate, the second plate and the third plate are arranged in parallel from top to bottom. Clamping grooves are formed in the two sides of a second insertion plate vertically. Each clamping groove communicates with a channel through a square hole between the clamping groove and the channel. A movable brake pad is placed in each clamping groove. A tie piece is arranged in the channel. Wedges are arranged on the two sides of the tie piece at intervals and face the same direction, and each wedge makes contact with the movable brake pad in the corresponding position. A threaded hole is formed in the end of the tie piece, and a tension bolt is installed in the threaded hole for tensioning connection. The anti-capsizing support of a bridge is of a pure mechanical structure, and long-term maintenance-free operation can be achieved; and in addition, main friction force happens to friction plates between the insertion plates, the automobile brake pads are used as the friction plates and are free of maintenance in the whole life, and the friction force of the brake pads can be adjusted conveniently through the tension bolt.

Description

technical field [0001] The invention relates to the technical field of bridge supports, in particular to a bridge anti-overturning support with excellent anti-seismic performance. Background technique [0002] Earthquakes cause serious damage to various traffic bridges, especially high-intensity earthquakes cause devastating blows to bridges, which are the main external factors for bridge failure and even overturning. Although various supports are designed in bridges to resist this damage, The effect is not very ideal. [0003] When the magnitude of the earthquake is large or the "hard resistance" of the structure is difficult to meet the expected seismic requirements due to some reasons, the use of seismic isolation technology to reduce the input seismic energy of the structure can achieve good results. The essential function of seismic isolation is to separate the structure or components from the seismic ground motion or support motion that may cause damage, cut off the t...
