Description

Technical Field

[0001] The utility model relates to the technical field of C-shaped steel, in particular to a general-purpose cold-formed C-shaped steel. Background Technique

[0002] C-shaped steel is widely used as purlins and wall beams in steel structure buildings, and can also be self-assembled into lightweight roof trusses, brackets and other building components. In addition, it can also be used for columns, beams, arms, etc. in mechanical and light industrial manufacturing. It is widely used in steel structure workshops and steel structure projects. It is a commonly used building steel, which is processed by cold bending of hot-rolled sheets. C-shaped steel has a thin wall, light self-weight, excellent cross-sectional performance, and high strength. Compared with traditional channel steel, 30% of materials can be saved with the same strength.

[0003] After retrieval, the utility model patent with the patent publication number of CN220844385U discloses a multi-layer galvanized cold-formed C-shaped steel, which relates to the field of C-shaped steel, including side support plates. A third telescopic rod is fixed below the inner side of the side support plates. The other end of the third telescopic rod is fixed with a pulley. The other side of the pulley is fixed with a rotating rod. The other side of the rotating rod is fixed with a rotating shaft. The other end of the rotating shaft is fixed with a connecting rod. The other end of the connecting rod is rotatably connected with a transmission rod. By setting the side support plates, end support plates, shelves, rotating rods, rotating shafts, connecting rods, transmission rods, motors and pulleys, when the motor is started, the formed C-shaped steel slides from the conveyor belt to one end of the shelf and continues to slide down along the shelf to reach the groove. The motor drives the transmission rod to rotate. When the transmission rod rotates to a high position, the groove catches the C-shaped steel. The transmission rod drives the C-shaped steel to continue to rotate. When it reaches another groove on the side support plate, the C-shaped steel is stuck in the groove, and automatic blanking can be realized.
