Description

Technical Field

[0001] The utility model relates to the technical field of C-shaped steel components, in particular to a highly fastened C-shaped steel component. Background Art

[0002] C-shaped steel is the main material for making light steel structures. It is made of cold-bent steel plates or steel strips. Not only can its wall thickness be made very thin, but it also greatly simplifies the production process and improves production efficiency. It can produce various profiles and C-shaped steels of different materials with uniform wall thickness but complex cross-sectional shapes that are difficult to produce by general hot rolling methods. In addition to being used in various building structures, C-shaped steel is also widely used in vehicle manufacturing, agricultural machinery manufacturing and other aspects.

[0003] For example, the authorization announcement number "CN220814228U" is named as a high-strength C-shaped steel component. Although the connection between the two C-shaped steels is strengthened by the fixing plates on the front and rear sides of the splint to prevent deformation of the connection, the high-strength C-shaped steel component, the connection between the two C-shaped steels, adopts horizontal bolts that penetrate the two sides of the splint to connect the two different C-shaped steels. However, the force direction of the bolts that penetrate the splint horizontally is the same as the force direction of the C-shaped steel. This results in that the two C-shaped steel connection positions in the vertical direction need to bear the tensile force and stress of the C-shaped steel connection, and also need to bear a part of the external vertical pressure acting on the C-shaped steel connection. This causes the bolt connection point to easily exceed the bearing range, and thus the compressive capacity of the high-strength C-shaped steel component is greatly reduced. As the use time continues to pass, the bolts at the connection position of the high-strength C-shaped steel component are prone to deformation and bending, which ultimately affects the overall tightness of the high-strength C-shaped steel component.
