[0021] Among them, the drawings are only used for illustrative explanations, and they only represent schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the utility model, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0022] The same or similar numbers in the drawings of the embodiments of the present invention correspond to the same or similar parts; in the description of the present invention, it should be understood that if the terms "upper", "lower", "left", "right", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0023] like Figure 1 As shown, a corrugated steel reinforced steel member includes a corrugated steel 1, a plurality of first connection holes 2 are provided at the trough position of the corrugated steel 1, and a row of first connection holes 2 is provided in each trough, and the first connection holes 2 in the same row are arranged evenly spaced. The corrugated steel 1 is also matched with a lower flange 3. In this specific embodiment, the lower flange 3 is a flat plate structure, and a plurality of second connection holes 4 are provided on the lower flange 3. The second connection holes 4 correspond to the first connection holes 2 one by one, and can be connected by a bolt assembly, so that the lower flange 3 is combined with the corrugated steel 1. An upper flange 7 is supported above the lower flange 3 by a side web 5 and / or a middle web 6. The upper flange 7 is arc-shaped, and the arc shape of the upper flange 7 is consistent with the waveform of the corrugated steel 1. The upper flange 7 is supported below the crest of the corrugated steel 1. The contact area between the upper flange 7 and the corrugated steel 1 is greatly increased, which will not cause stress concentration. The side webs 5 and / or the middle webs 6 play a supporting role to ensure the stability of the waveform. The lower flange 3 is a flat plate. After being connected to the corrugated steel 1 through the first connecting hole 2 and the second connecting hole 4, since the transverse hole spacing is the hole spacing of the standard waveform, after installation, the wave spacing distance can be controlled to limit its deformation.

[0024] like Figure 1 , 2As shown, as one of the specific embodiments of the corrugated steel reinforced steel member, the upper flange 7 is supported by the side webs 5 above the lower flange 3, one upper flange 7 corresponds to two side webs 5, the upper ends of the two side webs 5 are respectively welded to the two sides of the upper flange 7, and the lower ends are welded to the upper surface of the lower flange 3, that is, one upper flange 7 plays a supporting role through the two side webs 5 to ensure the stability of the corrugated steel 1, and is pressed under the crest of the corrugated steel 1 to ensure that stress will not be concentrated.

[0025] like Figure 1 , 3 As shown, as another specific embodiment of the corrugated steel reinforced steel member, the upper flange 7 is supported by the middle web 6 above the lower flange 3, one upper flange 7 corresponds to one middle web 6, the upper end of a middle web 6 is welded to the middle part of the upper flange 7, and the lower end is welded to the upper surface of the lower flange 3, and a middle web 6 supports the upper flange 7 in a vertical state to ensure the stability of the corrugated steel 1, and is placed under the crest of the corrugated steel 1 to ensure that stress will not be concentrated.

[0026] like Figure 1 , 4 As shown, as another specific embodiment of the corrugated steel reinforced steel member, which is also the one with the strongest supporting force, the upper flange 7 is supported by the side webs 5 and the middle webs 6 above the lower flange 3, and one upper flange 7 corresponds to two side webs 5 and one middle web 6. The upper ends of the two side webs 5 are respectively welded to the two sides of the upper flange 7, and the lower ends are welded to the upper surface of the lower flange 3; the upper end of a middle web 6 is welded to the middle part of the upper flange 7, and the lower end is welded to the upper surface of the lower flange 3. That is, the upper flange 7 plays a supporting role through a middle web 6 and two side webs 5 to ensure the stability of the corrugated steel 1, and it is pressed under the crest of the corrugated steel 1 to ensure that the stress will not be concentrated.

[0027] The above three support methods can be selected according to different loads. The side webs 5 and / or the middle webs 6 are combined with the corrugated steel 1 to increase the contact surface and will not cause stress concentration. The lateral hole spacing of the second connecting holes 4 of the lower flange 3 corresponds to the wave spacing of the corrugated steel 1, which can effectively limit the deformation of the corrugated shape after installation. The material of the lower flange 3, the side webs 5 and / or the middle web 6 and the upper flange 7 is also steel. After being combined with the corrugated steel 1, the moment of inertia is greatly increased (more than 1 times), which greatly improves the bearing capacity. The installation is simple. After the installation is completed, the inner wall or outer wall of the corrugated steel 1 becomes a flat surface, which is beneficial to improve its aesthetics and is also convenient for installing other components (such as welding other hanging parts).
