[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Figure 1 It is a schematic structural diagram of a steel structure sliding staircase for connecting different main structures according to an embodiment of the present invention.

[0023] like Figure 1As shown, the structure of the steel structure sliding staircase for connecting different main structures in the embodiment of the present invention includes a first floor beam 10, a second floor beam 20 and a staircase beam 30.

[0024] Furthermore, if Figure 1 As shown, the structure of the steel structure sliding staircase for connecting different main structures according to an embodiment of the present invention may also include treads 40 and platform plates 50, and the treads 40 and platform plates 50 may be arranged corresponding to the stair step beams 30.

[0025] For example, Figure 2 As shown, if the staircase step beam 30 includes two corresponding step beams 301 and 302, a tread plate 40 and a platform plate 50 may be arranged between the step beam 301 and the step beam 302. For example, a steel grating plate may be arranged between the step beam 301 and the step beam 302 as the tread plate 40 or the platform plate 50, wherein the steel grating plate may be fixed between the step beam 301 and the step beam 302 by welding or bolts to serve as the tread plate 40 or the platform plate 50. Specifically, connection supports may be arranged at equal distances on one side of the step beam 301 and the step beam 302, for example, bolt connection supports may be arranged at equal distances, and bolt connection holes may be correspondingly arranged on the steel grating plate, so that the steel grating plate may be bolted to the step beam 301 and the step beam 302 by connecting bolts, so as to fix the steel grating plate between the step beam 301 and the step beam 302 to serve as the tread plate 40 or the platform plate 50. Connecting the steel grating and stair beams by bolts can facilitate their assembly and disassembly, so that the steel grating can be replaced and repaired in time when it is damaged. In addition, the steel grating has good strength and light weight, which can ensure the quality of the treads and platform plates.

[0026] In addition, welding points can be set at equal distances on one side of the stair segment beam 301 and the stair segment beam 302, so that the steel grating plate can be fixed between the stair segment beam 301 and the stair segment beam 302 by welding to serve as a tread plate 40 or a platform plate 50. By fixing the steel grating plate between the stair segment beams by welding, it can be ensured that the steel grating plate is firmly connected between the stair segment beams. Therefore, the connection method between the steel grating plate and the stair segment beam can be selected according to actual needs to ensure that its practical effect is maximized, and in other embodiments of the present invention, other connection methods can also be used to achieve the connection between the steel grating plate and the stair segment beam.
