[0055] Figure 1 is a schematic structural view of a first profile member in a door leaf profile according to an embodiment of the present application, as shown in Figure 1 , and with reference to Figures 2 to 8 , the present application provides a door leaf profile. The door leaf profile comprises a first profile member 100.

[0056] The first profile member 100 is made of a metal material and processed by sheet metal processing, and has a first panel portion 200 extending in a first direction and a protruding portion protruding from a first panel surface 210 of the first panel portion 200. The first panel portion 200 has a first side and a second side opposite in a second direction. Therefore, the protruding portion has at least one, and at least one is connected to the first side or the second side of the first panel portion 200, or the protruding portion has at least two, and at least two are respectively connected to the first side and the second side of the first panel portion 200. The first panel portion 200 is in the shape of a flat plate extending in a first plane, and the first direction and the second direction are perpendicular in the first plane.

[0057] When the door leaf profile is used as a longitudinal beam, the first direction is the up-down direction, and of course when the door leaf profile is used as a transverse beam, that is, when the door leaf profile is arranged transversely, the first direction can also be the left-right direction.

[0058] The first side is one of the left and right sides, and the second side is the other side. Of course, in the case of the door leaf profile being used as a crossbeam, the first side and the second side refer to the upper side and the lower side, respectively.

[0059] The first plane is a plane in which the first panel portion 200 is located. In the case where the first panel portion 200 has a concave-convex structure, the extension plane is a plane in which other plane portions common to the concave-convex structure are located.

[0060] In the present embodiment, the protruding portion is formed on the first panel portion 200 of the first profile member 100, which enhances the overall strength of the first profile member 100 against flexural deformation and also improves the problem of damage due to flexural deformation when the door leaf profile encounters a collision. The arrangement of the protruding portion improves the structural strength of the door leaf profile, and thus the structural strength of the steel structure door, and reduces the likelihood of damage and deformation of the steel structure door due to a collision during transportation and assembly.

[0061] In some embodiments of the present application, as shown in Figures 1 to 6 The protruding portion has a first side wall 300 connected to the first panel portion 200. The first side wall 300 has at least one first flange portion 310 protruding toward the middle of the first panel portion 200 in the second direction. Each first flange portion 310 extends in the first direction. The at least one first flange portion 310 is in contact with or spaced apart from the first panel surface 210 in the third direction.

[0062] In the present embodiment, the first flange portion 310 is added to the first side wall 300 and protrudes toward the middle of the first panel portion 200 in the second direction, thereby forming an additional reinforcing structure on the first side wall 300 and further enhancing the strength of the first profile member 100.

[0063] When the first flange portion 310 is in contact with the first panel surface 210, a contact surface is formed between the first flange portion 310 and the first panel surface 210 to disperse external pressure, thereby further enhancing the structural strength of the first profile member 100. When the first flange portion 310 is spaced apart from the first panel surface 210 in the third direction, the manufacturing process of the steel structure door is simplified, and the production cost of the steel structure door is reduced.

[0064] In some embodiments of the present application, as shown in Figures 1 to 6 The first flange portion 310 is in the shape of a circular arc and has a first end directly or indirectly connected to the first panel portion 200 and a second end opposite to the first end. Furthermore,

[0065] The protruding part further has a second panel part 500 parallel to the first panel part 200, the second panel part 500 is spaced apart from the first panel part 200 in the third direction, and the second panel part 500 is located on the side of the first flange part 310 away from the first panel part 200 in the second direction. In addition, the first flange part 310 has at least one, and one second end of at least one of the second panel part 500, or the first flange part 310 has at least two, and one first end of at least two of the second panel part 500 indirectly connected to the second panel part 500 through the other at least one, and one second end connected to the second panel part 500.

[0066] In the embodiment, the first flange part 310 in the shape of a circular arc is convenient for forming and manufacturing, and the structure of the circular arc is beneficial to avoiding scratches on other objects or users caused by sharp corners, reducing the situation that the first profile member 100 is damaged by knocking, and improving the aesthetics, so that the ornamental value of the door leaf profile is improved.

[0067] The second panel part 500 spaced apart from the first panel part 200 in the third direction is provided, and the second panel part 500 extends in the second direction, so that the structural strength of the protruding part is higher. In addition, the first panel part 200 is arranged parallel to the first plane, so that the second panel part 500 can be arranged in a structure flush with the outer surface of the steel structure door. The structure that the second panel part 500 is flush with the outer surface of the door leaf profile improves the ornamental value of the appearance of the door leaf profile, and also avoids the situation that the protruding part is scratched on the user or other objects due to the protrusion of the surface of the door leaf profile in the third direction.

[0068] In some embodiments of the utility model, as shown in Figures 1 to 6 In the case that the first flange part 310 has one, and the first flange part 310 is spaced apart from the first panel part 200 in the third direction, the first flange part 310 opens away from the first panel part 200 in the second direction, and the first flange part 310 has a first end close to the first panel part 200 and a second end opposite to the first end.
