Detailed Implementation

[0023] To facilitate understanding by those skilled in the art, the following description is provided in conjunction with embodiments and appendices. Figure 1-7 The present invention will be further described below. The content mentioned in the embodiments is not intended to limit the present invention.

[0024] See Figure 1-7A modular steel ladder structure includes a steel ladder body 1, a first support column 2 and a second support column 3 vertically and parallelly fixed to the front side of the steel ladder body 1, a first steel ladder platform 5 fixed to the lower right side of the first support column 2, a second steel ladder platform 6 fixed to the left side of the middle part of the second support column 3, a ladder column 4 fixed to the top right side of the second steel ladder platform 6, and a third steel ladder platform 7 fixed to the top left side of the ladder column 4. A first connecting beam 8 is horizontally fixed between the middle part of the first support column 2 and the upper middle part of the second support column 3. A first load-bearing beam 81 is fixed to the rear side of the first connecting beam 8, and a second load-bearing beam 82 is fixed to the top rear side of the first support column 2. The first steel ladder platform... 5. The second steel ladder platform 6, the first load-bearing beam 81, the third steel ladder platform 7, and the second load-bearing beam 82 are arranged sequentially from bottom to top. The steel ladder body 1 includes a first steel ladder 11 that is inclinedly fixed between the ground and the front side of the first steel ladder platform 5, a second steel ladder 12 that is inclinedly fixed between the rear side of the first steel ladder platform 5 and the rear side of the second steel ladder platform 6, a third steel ladder 13 that is inclinedly fixed between the front side of the second steel ladder platform 6 and the front side of the first load-bearing beam 81, a fourth steel ladder 14 that is inclinedly fixed between the rear side of the first load-bearing beam 81 and the rear side of the third steel ladder platform 7, and a fifth steel ladder 15 that is inclinedly fixed between the front side of the third steel ladder platform 7 and the front side of the second load-bearing beam 82.

[0025] The modular steel ladder of this utility model adopts a first steel ladder platform 5, a second steel ladder platform 6, a first load-bearing beam 81, a third steel ladder platform 7 and a second load-bearing beam 82 arranged sequentially from bottom to top. This can reasonably distribute the pressure borne by the steel ladder body 1 and increase its structural strength. Moreover, the utility model adopts a modular design, and each component can be standardized in the factory, enabling rapid assembly on site, shortening construction time, and facilitating later maintenance.

[0026] In this embodiment, the first steel ladder 11 includes a first connecting platform 111 and two steel ladder units 112 respectively inclined and fixed to the left and right sides of the first connecting platform 111. Each steel ladder unit 112 includes two first support beams 113 inclined and opposite to each other and a first step ladder 114 welded between the tops of the two first support beams 113. By setting the first steel ladder 11, the connection between the ground and the first steel ladder platform 5 is realized. Moreover, the steel ladder units 112 can be produced in a factory in a standardized manner. During on-site installation, since the connection method between the components is relatively simple and clear, the installation time and labor costs can be reduced.

[0027] In this embodiment, the modular steel ladder structure also includes an embedded part 9, which is inverted L-shaped. Multiple fixing holes 91 are provided on the top and right side of the embedded part 9. The bottom of the first steel ladder 11 has a concave corner notch 115 that matches the external corner of the embedded part 9. An anchoring hole (not shown in the figure) is provided on the contact surface of the concave corner notch 115 corresponding to the position of each fixing hole 91. The external corner of the embedded part 9 is embedded into the concave corner notch 115. An anchor bolt 92 is inserted into each fixing hole 91, with one end of the anchor bolt 92 embedded in the corresponding anchoring hole and the other end embedded in the ground. The inverted L-shaped design of the embedded part 9 allows it to penetrate deep into the ground, forming a firm and secure connection with the ground. When the external corner of the embedded part 9 is inserted into the internal corner notch 115 at the bottom of the steel ladder, and the embedded part 9 is connected to the steel ladder body 1 by the anchor bolt 92, the steel ladder can be firmly connected to the ground with the help of the embedded part 9 when subjected to horizontal or vertical forces, effectively resisting displacement and shaking, thereby greatly enhancing the stability of the entire modular steel ladder structure on the ground and ensuring the safety of the steel ladder during use.

[0028] In this embodiment, the first steel ladder platform 5 includes a first platform steel frame 51 and a first platform steel plate 52 welded to the top of the first platform steel frame 51. The first platform steel frame 51 includes a third load-bearing beam 53 fixed to the lower rear side of the first support column 2, multiple first crossbeams 54 fixed parallel to the right side of the third load-bearing beam 53, and multiple first longitudinal beams 55 welded longitudinally between any two adjacent first crossbeams 54. The main body of the first platform is formed by the first platform steel frame 51 formed by the staggered welding of the first crossbeams 54 and the first longitudinal beams 55, which significantly enhances the rigidity of the first steel ladder platform 5, making it less prone to deformation when bearing loads, ensuring the flatness and stability of the platform, and providing reliable support for personnel walking and equipment placement. The third load-bearing beam 53 provides support for the entire first steel ladder platform 5.

[0029] In this embodiment, the second steel ladder 12 includes two opposing second support beams 121. Each second support beam 121 includes a horizontal section 122 and an inclined section 123 fixed to the left side of the horizontal section 122. A step steel plate 124 is welded between the tops of the horizontal sections 122 of the two second support beams 121, and a second step 125 is welded between the tops of the inclined sections 123 of the two second support beams 121. By setting up the second steel ladder 12, the connection between the first steel ladder platform 5 and the second steel ladder 12 platform 6 is realized. The two second support beams 121 serve as the main support structure of the second steel ladder 12. The design of its horizontal section 122 and inclined section 123 can effectively distribute and transmit the load generated by the user during climbing. The strength of the horizontal section 122 can withstand the weight of the user when standing on the platform, while the inclined section 123 can withstand the longitudinal force during climbing, so that the entire steel ladder remains stable during use and will not deform or sway due to excessive local stress.

[0030] In this embodiment, the second steel ladder platform 6 includes a second platform steel frame 61 and a second platform steel plate 62 welded to the top of the second platform steel frame 61. The second platform steel frame 61 includes a fourth load-bearing beam 63 fixed to the rear side of the middle of the second support column 3, a second crossbeam 64 fixed to the left side of the middle of the fourth load-bearing beam 63, and two outer frame beams 65 symmetrically fixed to the front and rear sides of the left end of the second crossbeam 64. The middle of both outer frame beams 65 is bent to the right and fixedly connected to the left side of the fourth load-bearing beam 63. Multiple second longitudinal beams 66 are welded between the second crossbeam 64 and the two outer frame beams 65. By setting the second steel ladder platform 6, the downward load applied by the second steel ladder 12 to the upper platform and the pressure load applied to the lower platform can be effectively reduced, thereby reducing the probability of deformation of the steel ladder body. The reliability of the steel ladder body connection is better, the stress of the overall structure is reasonable, and the safety is high.

[0031] In this embodiment, the third steel ladder 13 includes two third support beams 131 arranged at an incline and opposite angles, and a third step ladder 132 fixed between the tops of the two third support beams 131.

[0032] In this embodiment, the third steel ladder platform 7 has the same structure as the second steel ladder platform 6, and the fifth steel ladder 15 has the same structure as the first steel ladder 11. By setting the same structure, the production process can be simplified and costs reduced.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
