Introduction
The H-shaped steel is a kind of hot-rolled section steel and a section steel, which is a common section steel for the construction structures. Its cross-section characteristics of H-shaped steel in the form of letter H can effectively improve the rigidity and bearing capacity of the members, and also make the steel sections to be compact and lightweight.
Design Principles of H-shaped Steel Holes
1. The size and position of the hole shall be determined according to the force, shape and size of the member and the design requirement, and the diameter of the hole shall not be too large.
2. The arrangement of H-shaped steel holes should be reasonable, clean and neat in order to ensure the symmetrical that is conducive to welding and the overall beauty of the structure.
3. When producing H-shaped steel holes, consider the size of the weld and the size of the weld bead. The size of the weld and the degree of the weld shall meet the requirements of the design.
4. When producing the weld hole of the H-shaped steel, the process should be fully considered to repair the welding deformation caused by punching and cutting so as to ensure the accuracy of the hole size and ensure the normal use of the structure.
5. When producing holes on both ends of the H-shaped steel, the distance of the two holes shall meet the requirements. The two holes should not be too close or too far apart to avoid welding or increasing the welding or increasing the welding deformations.
6. When the web of the H-shaped steel needs to be closed, the size of the closure and the bearing capacity of the welding seam shall be considered, and the positioning and welding shall meet the requirements of the national standard.
Conclusion
In short, the design of the H-shaped steel holes shall comply with the national standard, pay attention to the reasonable design, safe operation, and large deformation, so as to ensure the normal use of the structure and ensure the safety of the users.
