[0002] In various industries in the industrial field, steel structure workshops are the most common structural forms. The bracket is one of the important components in the steel workshop structure. In the process of structural design, the conventional method is to set the steel bracket by welding in the factory on the steel column to support components such as crane beams. For new projects, the steel bracket can be welded on the steel column in a non-stressed state in the factory to achieve this. For the renovation of existing projects, it is necessary to install the steel bracket on the existing steel column in a stressed state on-site. However, the on-site groove welding in the direction of the vertical length of the steel column has a great impact on the bearing capacity of the steel column in a stressed state, and it is quite difficult to implement the welding at high altitude, and the welding quality cannot be guaranteed.
