[0003] At present, the design and processing of aluminum formwork stairs in China mainly use aluminum dogtooth and step formwork. In this way, the aluminum parts are all special-shaped parts, which cannot be recycled after a project is used, and the cost is high. In addition, the quality of casting molding of aluminum step stairs is often poor due to improper reinforcement during construction (due to the aluminum material itself), and the special-shaped parts are very easy to be damaged during rough construction.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-4 , the utility model provides a technical solution: a new type of steel step, including a cover plate 1 made of steel, a first frame 2, a first panel 4, a second frame 5 and a second panel 6;

[0030] The first panel 4 has an L-shaped cross section;

[0031] The sealing plate 1 and the second panel 6 are arranged vertically on both sides of the first panel 4, the sealing plate 1 and the second panel 6 are welded to the first panel 4, the cross section of the second panel 6 is a right-angled trapezoid, the second frame 5 is arranged parallel to the inner side of the hypotenuse of the second panel 6, and the second frame 5 is welded to the hypotenuse of the second panel 6. When the steel step is installed, the sealing plate 1 and the second frame 5 can be assembled on the wall or the mounting frame by bolts, thereby eliminating the process of opening holes matching the bolts on the sealing plate 2 or the second frame 5, and at the same time, the material cost of the sealing plate 2 and the second frame 5 is also saved;

[0032] The first frame 2 is arranged vertically at the end of the first panel 4 and has the same length as the first panel 4. When adjacent steel steps are spliced, the structure can be made more compact. The first frame 2 is welded to the sealing plate 1 and the first panel 4 and the second frame 5 and the second panel 6;

[0033] A plurality of first screw holes 11 are provided on the sealing plate 1, and the first screw holes 11 are distributed along the L-shaped direction of the sealing plate 1; a plurality of third screw holes 51 are provided on the second frame 5, and the third screw holes 51 are evenly distributed along the length direction of the second frame 5; a plurality of second screw holes 21 are provided on the bearing surfaces of the first frame 2 and the first panel 4 away from the first frame 2, and the second screw holes 21 are evenly distributed along the length direction of the first frame 2.

[0034] Specifically, Figure 1 As shown, a plurality of reinforcing ribs 3 are vertically arranged on the bearing surface on one side of the first panel 4, and the reinforcing ribs 3 are welded to the first panel 4 and the first frame 2, which can effectively improve the overall structural strength and structural stability of the steel step.

[0035] Specifically, Figure 1 As shown, the cross-section of the sealing plate 1 and the reinforcing rib 3 is L-shaped with a bevel at one end, and the inclination angle of the bevel is the same as the inclination angle of the bevel on the second panel 6.

[0036] Specifically, Figure 2 As shown, a fixing block 7 corresponding to the position of the second screw hole 21 is welded and connected to the bearing surface on the side of the first panel 4 away from the first frame 2, and a fourth screw hole 71 corresponding to the second screw hole 21 is opened on the fixing block 7. The fourth screw holes 71 are evenly distributed along the length direction of the first panel 4. The fixing blocks 7 are arranged linearly on the first panel 1. When adjacent steel steps need to be installed, the fixing blocks 7 can be connected to the first frame 2 on another steel step by bolts, thereby strengthening the strength of the entire steel step and extending the service life of the steel step.

[0037] In this embodiment, multiple steel steps can be quickly disassembled and assembled, and because the second screw hole 21 and the fourth screw hole 71 are connected up and down, the connecting piece will not bear the longitudinal shear force, and the hole wall of the first screw hole 11 and the third screw hole 51 will not be worn by force to cause the structure to be misaligned, so the connection strength between the upper and lower layers of steel steps and the stability of the overall structure can be greatly improved. Even if it is damaged due to overload, it is usually only the connecting piece that is damaged. When repairing, only the connecting piece needs to be replaced, and there is no need to replace the entire steel step, which greatly reduces the maintenance cost.

[0038] Working principle: When in use, use bolts or screws to fix the closing plate 1 and the second frame 5 on the mounting frame, so that the closing plate 1 and the second panel 6 are in contact with or parallel to the walls on both sides, and the installation of a steel step is completed. After that, the next steel step is installed, and between adjacent steel steps, the second screw hole 21 of the first frame 2 on the steel step above the stairs and the fourth screw hole 71 of the fixing block 7 on the steel step below the stairs are aligned with each other, and then, the bolt is passed between the second screw hole 21 and the fourth screw hole 71 to fix the two steel steps together. According to this scheme, other steel steps are installed in turn. After all the steel steps are installed, check and clean the steel steps.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
