Description

Technical Field

[0001] The utility model relates to the technical field of angle steel flanges, and more specifically, to an angle steel flange connection structure. Background Technique

[0002] An angle steel flange refers to an angle steel or angle iron that is bent through a special device. After processing, the two sides of the angle steel still remain perpendicular at 90°, without flanging and without wrinkles.

[0003] After retrieval, an angle steel flange structure device for rectangular air duct connection with the existing publication number CN208764513U includes a rectangular flange structure formed by welding two long angle steels and two short angle steels; long circular holes are opened on both the long angle steels and the short angle steels to meet the requirements of bolt connection errors brought by mass production; the widths of the long angle steels and the short angle steels are both B1, the length of the long angle steel is L1, and the length of the short angle steel is L2; the length of the long side of the rectangular air duct is a, and the length of the short side of the rectangular air duct is b; aiming at the problem that each group of flanges needs to be paired and positioned once during processing, the interchangeability and mass production problems of rectangular flanges are solved. Moreover, long circular holes are opened on the angle steels to meet the interchangeability requirements of angle steel flanges, and a punching machine is used for punching to meet the requirements of mass production.

[0004] An angle steel flange will be installed at the port position of the air duct. When connecting the air ducts at adjacent positions, the end face position of the air duct is fixed through the angle steel flange and a locking member. However, the commonly used angle steel flange has a single structure and low structural strength, which affects the service life. Therefore, we propose an angle steel flange connection structure to solve the above existing problems. Content of the Utility Model
