Detailed Description

The present invention will be further described with reference to the accompanying drawings 1-6 and the specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

Example 1:

this embodiment a light gauge steel of H type two-chamber structure, including first "C" type bending groove 1 and the second "C" type bending groove 2 that the symmetry set up, set up "H" type portion 3 of bending between first "C" type bending groove 1 and the second "C" type bending groove 2. The first C-shaped bending groove 1, the second C-shaped bending groove 2 and the H-shaped bending part 3 are integrally formed by bending plates. As shown in fig. 1, in this embodiment, the plate is first bent to the right by 90 degrees to form the bottom surface of the first "C" shaped bending groove 1, then bent to the lower by 90 degrees to form the right side surface of the first "C" shaped bending groove 1, then bent to the upper by 180 degrees to form the left side edge of the "H" shaped bending portion 3 closely attached to the right side surface of the first "C" shaped bending groove 1, then bent to the right by 90 degrees to form the middle beam of the "H" shaped bending portion 3, then bent to the lower by 90 degrees to form the right side edge of the "H" shaped bending portion 3, then bent to the upper by 180 degrees to form the left side edge of the second "C" shaped bending groove 2, then bent to the right by 90 degrees to form the bottom surface of the second "C" shaped bending groove 2, and finally bent to the lower by 90 degrees to form the right side edge of the second "C" shaped bending groove 2. Specifically, the bottom edges of the left side edge of the first C-shaped bending groove 1 and the right side edge of the second C-shaped bending groove 2 of the light steel keel are bent inwards to form a bending angle 6, and the bending angle 6 can increase the bending resistance of the C-shaped bending groove.
