AI Technical Summary
The existing steel structure stair treads are insufficient in terms of load-bearing capacity and deformation resistance, resulting in poor performance.
Weld "T"-shaped iron strips under the treads of the stair treads and angle irons at the inside corners. At the same time, add lining plates and sound insulation cotton between the stair treads. The treads and the front panel are connected by hooks to form a reinforced structure.
This improved the load-bearing capacity of the steel structure staircase, reduced deformation, and enhanced the stability and durability of the structure.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure technology, specifically to steel structure staircases. Background Technology
[0002] The steel structure staircase includes a staircase frame on which multiple stair treads are installed. Each stair tread includes horizontally arranged steps and vertically arranged facing panels. The steps and facing panels are integrally formed, creating a structure with externally convex corners.
[0003] In the existing technology, the stair slabs on steel structure staircases are made of bent steel plates without any supporting parts. This results in disadvantages such as low load-bearing capacity and easy deformation, which affects the usability of steel structure staircases. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a steel structure staircase that is strong in load-bearing capacity and not easily deformed.
[0005] The technical solution of this utility model is implemented as follows: A steel structure staircase includes a staircase frame, on which multiple stair treads are installed. Each stair tread includes a horizontally arranged step and a vertically arranged facing plate. The step and facing plate are integral and form a structure with external convex corners. The feature is that multiple T-shaped iron bars with a T-shaped cross-section are welded under the step, and the length direction of the T-shaped iron bars is parallel to the length direction of the stair tread.
[0006] Furthermore, below the external corner is the internal corner, where an angle iron is welded, with the length of the angle iron parallel to the length of the stair tread.
[0007] Furthermore, there is a lining board underneath the stair tread, and a layer of sound insulation cotton between the stair tread and the lining board.
[0008] Furthermore, the tread has an upward extension, which is a tread extension. The extension has a hook, which is an upper hook. The lower part of the facing panel has a lower hook that matches the upper hook. The upper hook on one stair tread is hooked to the lower hook of the adjacent stair tread.
[0009] The beneficial effects of this utility model are: such a steel structure staircase has the advantages of strong load-bearing capacity and is not easily deformed. Attached Figure Description

[0014] The components include: 1. Staircase frame; 2. Staircase slab; 21. Step tread; 211. Step tread extension; 2111. Upper hook; 22. Front panel; 221. Lower hook; 23. External corner structure; 3. "T" shaped iron strip; 4. Angle iron; 5. Lining plate; 6. Sound insulation cotton. Detailed Implementation
[0015] The present invention will be further described below with reference to the accompanying drawings.
[0016] like Figure 1 , 2 As shown, a steel structure staircase includes a staircase frame 1, on which multiple stair treads 2 are installed. Each stair tread includes a horizontally arranged step tread 21 and a vertically arranged facing tread 22. The step tread and the facing tread are integrally formed, and the step tread and the facing tread form a structure 23 with an externally convex corner. The staircase is characterized by having multiple T-shaped iron bars 3 with a T-shaped cross-section welded to the bottom of the step tread. The length direction of the T-shaped iron bars is parallel to the length direction of the stair tread.
[0017] Furthermore, below the external corner is the internal corner, and an angle iron 4 is welded at the internal corner, the length of which is parallel to the length of the stair tread.
[0018] Furthermore, there is a lining board 5 underneath the stair tread, and a layer of sound insulation cotton 6 between the stair tread and the lining board.
[0019] Furthermore, the tread has an upward extension, which is a tread extension 211. The extension has a hook, which is an upper hook 2111. The underside of the facing panel has a lower hook 221 that matches the upper hook. The upper hook on one stair tread is hooked to the lower hook of the adjacent stair tread.
[0020] The above description is only a specific embodiment of the present utility model, but the structural features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
