Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated housing technology, specifically a highly durable steel structure for prefabricated housing. Background Technology
[0002] Staircase steel treads play a crucial role in prefabricated housing. In existing technology, the two ends of the steel treads are welded to the side beams of the staircase (the longitudinal support structure of the staircase).
[0003] However, after a period of use, weld cracks are prone to appear due to the small welding area. In addition, steel pedals are prone to bending and deformation after a period of use, resulting in poor durability and significant safety hazards in humid or slippery environments.
[0004] Therefore, we propose a highly durable prefabricated steel structure for houses. Utility Model Content

[0009] Preferably, a countersunk hexagonal bolt is provided between the anti-slip pad and the steel plate, and the anti-slip pad is installed on the upper outer surface of the steel plate by means of the countersunk hexagonal bolt.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] This embodiment is a highly durable prefabricated steel structure for housing.
[0026] like Figure 1-4 As shown, the device includes a steel plate 1, with support plates 4 at both ends of the lower outer surface of the steel plate 1, reinforcing ribs 5 installed on the front and rear sides of the lower outer surface of the steel plate 1, an anti-slip pad 2 on the upper outer surface of the steel plate 1, and limiting grooves 7 at both ends of the upper outer surface of the support plate 4. Mounting holes 6 are provided at the four corners of the upper outer surfaces of the steel plate 1 and the anti-slip pad 2.
[0027] An internal hexagon countersunk bolt 3 is provided between the anti-slip pad 2 and the steel plate 1. The anti-slip pad 2 is installed on the upper outer surface of the steel plate 1 through the internal hexagon countersunk bolt 3. The two ends of the reinforcing rib 5 are inserted into the limiting groove 7. The outer wall of the reinforcing rib 5 is welded to the support plate 4. The upper outer surface of the reinforcing rib 5 is welded to the lower outer surface of the steel plate 1. The internal hexagon countersunk bolt 3 is threaded to the mounting hole 6.
[0028] It should be noted that this utility model is a highly durable prefabricated steel structure. It includes two sets of steel plates 1 and support plates 4. One side of each support plate 4 is welded to both ends of the steel plate 1 and attached to the side beams of the staircase (the longitudinal support structure of the staircase). The support plates 4 increase the welding area of the steel plate 1 during installation. A larger welding area means stronger connection force, thereby reducing the risk of shaking or deformation due to vibration or impact during use, making the stair treads more stable and reliable. The reinforcing ribs 5, fixed between the support plates 4 and the lower outer surface of the steel plate 1, not only significantly improve the load-bearing capacity of the stair treads and ensure safety during use, but also further enhance the durability of the structure, allowing the stair treads to withstand greater loads without easily being damaged. The anti-slip mats 2, installed on the steel plate 1, effectively reduce the risk of slipping and increase friction during walking, making the stair treads safer and more reliable.
[0029] It should be noted that, in this document, relational terms such as first and second (number one, number two), etc., are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
