Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a hemisphere and steel pipe combined structure. Background Art

[0002] The connection and fixation of the steel pipe and the hemispherical support are usually fixed by welding, but the hemisphere and the steel pipe are spherical and round. If the steel pipe and the hemisphere are directly welded, the hemisphere and the steel pipe are prone to rolling, and the steel pipe needs to be continuously supported. Once the hemisphere and the steel pipe are displaced, the position of the steel pipe welded on the hemisphere will change. Welding multiple groups of steel pipes on the surface of the hemisphere cannot ensure the fixed position of the hemisphere, resulting in the inability to assemble the connection structure between the hemisphere and the steel pipe during use. If a clamp is used to fix the steel pipe and the hemisphere, the steel pipe needs at least three fixing points during welding. Only by forming a triangular support can the hemisphere and the steel pipe be fixed firmly. The hemisphere cannot be fixed well even if a clamp is used, but the volume of the clamp itself affects the welding speed between the steel pipe and the hemisphere, and at the same time, the steel pipe and the hemisphere connection support also need to be welded with other components, and the remaining auxiliary components also need to be fixed, resulting in an increase in the types and quantities of fixing clamps used. Multiple numbers of clamps need to be operated and fixed, which will seriously affect the production speed of the hemisphere and steel pipe connection support. At the same time, the use of multiple numbers of clamps increases the production cost of the hemisphere and steel pipe connection support, and the economic benefits are low.

[0003] To this end, we propose a combined structure of a hemisphere and steel tube. Utility Model Content
