Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a support bracket with high safety performance for bridge construction. Background Art

[0002] Bridges generally refer to structures erected over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern, rapidly developing transportation industry, bridges are also extended to buildings that are erected across mountain streams, poor geology, or to meet other transportation needs to make travel more convenient. In the process of bridge construction, the bridge deck needs to be supported, and the support bracket is a special device that performs this support work. Some existing support brackets on the market use a main support column and multiple secondary support columns to connect in the form of a reinforcing arm to support the bridge deck. Because of their structure, they can share the force they bear to ensure that they have sufficient bearing capacity to ensure safety during the construction process. However, the reinforcing arms for force transmission and auxiliary support are not easy to assemble and install due to their own structural factors and equipment volume factors.
