Cage for high-altitude welding construction of net frame

Abstract

The invention discloses a cage for high-altitude welding construction of a net frame. The net frame is mainly formed by connecting multiple rod pieces. The cage comprises a cage body which is ina quadrangular shape. A bottom plate is arranged on the bottom of the cage body. A first hook and a second hook are arranged on one side wall of the cage body. A third hook is arranged on the other side wall parallel to the side wall where the first hook and the second hook are located. The first hook, the second hook and the third hook each comprise a bent hook body. The bending directions of the hookbodies of the first hook and the second hook are the same. The bending directions of the hook bodies of the third hook and the first hook are perpendicular. The curvature radius of the first hook, thesecond hook and the third hook is larger than or equal to the radius of the rod pieces. The first hook, the second hook and the third hook are equal in height. The cage can adapt to the high-altitudenet frame structure, the cage can be hooked effectively, constructors can stand in the cage to carry out welding construction, the welding quality and the construction efficiency are improved, and meanwhile, the safety of high-altitude operation of the constructors is improved.

Description

technical field [0001] The invention relates to the technical field of steel structure buildings, in particular to a hanging cage for high-altitude welding construction of a network frame. Background technique [0002] With the development of large-span space structures, grid structures have been widely used, such as airport terminals, toll stations, factory buildings and other buildings, all of which have application examples of grid structures. The grid structure has reasonable force, strong rigidity, and light weight. It can give full play to the tensile and compressive properties of the material, reduce the adverse effects of bending moment and shear force on the material, and the shape is changeable, and the grid size can be adjusted according to the requirements of the building. , to meet different usage needs. At present, the material selection of this structure is mainly steel, and the application of steel structure grid is the most common. [0003] In the construc...

Problems solved by technology

[0003] In the construction of the steel structure grid workshop, it is necessary to carry out process lifting point welding on the bolt balls or welding balls of the grid roof structure to be used for welding other equipment. The grid rods are used for welding construction. Long-term construction is prone to fatigue, and the body cannot be effectively kept stable. The welding quality cannot be guaranteed, the construction efficiency is low, and the work safety of the construction personnel cannot be guaranteed, which cannot meet the requirements of on-site construction.
