Description

Technical Field

[0001] The utility model belongs to the technical field of bridge supports, and particularly relates to a bridge support bracket. Background Technique

[0002] Highway bridge projects include the main bridge project and the auxiliary engineering facilities in the overall bridge location. There are many auxiliary engineering facilities, such as structures for regulating water flow like revetments and guide dikes to maintain the stability of the river channel at the bridge location, approach bridges connecting the bridgehead to the highway, railings on the bridge deck to prevent wheel collisions, sidewalk railings to ensure pedestrian safety, as well as bridge signals, navigation signs under the bridge, and bridge deck lighting equipment. In addition, bridges located in earthquake-prone areas are also equipped with earthquake prevention devices, additional devices for preventing wind-induced resonance are installed on the stay cables of cable-stayed bridges, mechanical devices are installed on movable bridges, and ice-breaking devices are installed on bridges over glaciers. Therefore, bridge engineering is related to structural engineering, foundation engineering, hydraulic engineering, and traffic engineering, and is also related to disciplines such as meteorology, hydrology, engineering geology, building materials, testing technology, construction machinery, aesthetics, and environmental protection. It is a highly comprehensive engineering technology.

[0003] In order to ensure the stability of the bridge, a support bracket device is usually required to support the bridge. However, when the existing support brackets support the bridge, due to the fact that there is a certain slope at the bottom of some bridges, most of the existing bridge support brackets can only support in the vertical direction, which is not convenient for adjusting the support according to the slope of the bridge bottom, and the flexibility is low. To solve the above problems, a bridge support bracket is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a bridge support bracket to solve the problem that when the existing support brackets support the bridge, due to the fact that there is a certain slope at the bottom of some bridges, most of the existing bridge support brackets can only support in the vertical direction, which is not convenient for adjusting the support according to the slope of the bridge bottom, and the flexibility is low.
