[0023] In industrial and civil buildings, fixed vertical ladders are widely used as vertical transportation facilities. These ladders are installed vertically at a 90-degree angle to the exterior wall of the building, using a steel structure, and primarily serve maintenance work on rooftops or platforms. However, traditional fixed vertical ladders have significant limitations: their length is not adjustable, and the overlap direction between the top and the platform or roof is completely fixed, meaning users can only access the work surface from the climbing direction. In complex building layouts, such as irregular platform locations or obstructions in the walls, fixed-direction ladders may not be able to be directly overlapped, limiting the choice of installation location and making it difficult to flexibly adjust according to actual needs, thus affecting the rational utilization of building space.

[0024] Therefore, such as Figures 1 to 9As shown, the multi-directional splicing straight climbing ladder 200 proposed in this utility model includes: a climbing ladder assembly 100, a climbing ladder 200, and a protective assembly 300. The climbing ladder assembly 100 includes multiple ladders. These ladders are detachably connected together. Each ladder includes a pair of opposing ladder beams and treads positioned between the beams. The treads have a circular cross-sectional shape. The climbing ladder assembly 100 is composed of multiple detachable ladders, allowing for flexible adjustment of the total length according to building height, enabling rapid adaptation to different floor height requirements. The climbing ladder 200 is detachably connected to the climbing ladder assembly 100. The climbing direction of the climbing ladder 200 may be the same as or different from that of the climbing ladder assembly 100. In buildings with complex layouts, the angle of the climbing ladder 200 can be adjusted to achieve barrier-free connection, reducing worker movement in hazardous areas, flexibly adapting to various application scenarios, and improving equipment flexibility. The protective assembly 300, together with the climbing ladder assembly 100, forms a climbing passage, providing reliable protection for climbers and improving operational safety.

[0025] In some embodiments of this utility model, considering factors such as construction, stress performance, and material conservation, the cross-sectional shape of the tread can be a hollow triangle, the cross-sectional shape of the ladder beam is rectangular, the inner side of the rectangular tube of the ladder beam is provided with tread mounting holes opened according to the shape of the tread, the tread is a hollow rod with a triangular cross-section, the surface of the tread is provided with anti-slip texture, and the two sides of the tread are provided with assembly holes. During installation, the tread is directly inserted into the tread mounting holes of the ladder beam and the two are fixed with fasteners, such as bolts, nuts, and screws.

[0026] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 8 As shown, the ladder includes a first ladder component 120 and a platform 130. The platform 130 has a regular rectangular structure and is vertically mounted on top of the first ladder component 120. One side of the platform 130 is used to install the climbing ladder assembly 100, and the other side is used to install the climbing ladder 200. The platform 130 is provided with a through groove 131, and the first ladder component 120 is fixedly connected to the groove wall of the through groove 131. The protective assembly 300 includes a first cover 320. The length of the first cover 320 is less than or equal to the length of the first ladder component 120. The top of the first cover 320 is fitted around the outside of the through groove 131, which can improve the safety of the first ladder component 120. The first cover 320 is located on the side of the first ladder component 120 facing the through groove 131, which is conducive to the climber's passage up and down.

[0027] In some embodiments of this utility model, such as Figure 3As shown, the platform 130 has multiple first positioning holes 150 around its perimeter, and the ladder 200 has two second positioning holes at its bottom, spaced apart. The first positioning holes 150 are grouped in pairs, with the first and second positioning holes corresponding to each other. At least two of the first positioning holes 150 cooperate with fasteners to secure the ladder 200.

[0028] In some embodiments of this utility model, such as Figures 1 to 5 As shown, the protective component 300 includes multiple guardrails 340. The bottom of each guardrail 340 is provided with a third positioning hole, which corresponds to the first positioning hole 150. The bottom of the guardrail 340 is fixedly connected to the climbing ladder component 100. Multiple guardrails 340 together form a protective structure. The protective structure has an opening on one side for avoiding the climbing ladder 200.

[0029] Specifically, in some embodiments of this utility model, such as Figure 3 As shown, guardrail 340 is installed around the platform 130, with an opening on the front for clearance. Ladder 200 is installed on the platform 130, and the climbing direction of ladder 200 is the same as that of ladder assembly 100. This means that climbers can climb upwards along ladder assembly 100, and upon reaching the top, can directly ascend the platform or building without turning around. In some applications, this is suitable for conventional building platforms, where ladder assembly 100 can contact the wall, and ladder 200 is attached to the top of the building platform.

[0030] In other embodiments of this utility model, such as Figure 4 As shown, the guardrail 340 is installed around the platform 130, with a clearance opening on the left. The ladder 200 assembly can be installed facing left, allowing climbers to turn left after ascending from the ladder assembly 100 and climb the ladder 200 to the platform or building. Climbers can smoothly transition from the ladder assembly 100 to the ladder 200 and then to the platform or building without complex turning or large body adjustments, facilitating rapid access to the designated location. The guardrail 340 provides reliable support and grip points for climbers, reducing the risk of falls due to instability when turning at heights.

[0031] In other embodiments of this utility model, such as Figure 5As shown, guardrail 340 is installed around platform 130, with an opening on the right side for clearance. Ladder 200 can be installed facing right, allowing climbers to turn right after ascending ladder component 100 and climb ladder 200 to the platform or building. Climbers can smoothly transition from ladder component 100 to ladder 200 and then ascend to the platform or building without complex turning or large body adjustments, facilitating rapid access to designated locations.

[0032] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 6 As shown, the ladder includes a second ladder member 110, which is positioned below the first ladder member 120. The protective assembly 300 includes a second cover member 310, which is fitted onto the top of the second ladder member 110. The length of the second cover member 310 is less than the length of the second ladder member 110. In some applications, since the first ladder member 120 is closer to the ground, the protective assembly 300 does not need to be installed at the bottom of the first ladder member 120 to prevent obstruction to the climber. The climber can climb up the first ladder member 120 from the ground and then to the top of the climbing assembly 100.

[0033] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 7 As shown, the ladder includes multiple third ladder members 140, and the protective assembly 300 includes multiple third cover members 330. The length of the third cover member 330 is less than or equal to that of the third ladder member 140. The multiple third ladder members 140 are detachably connected between the second ladder member 110 and the first ladder member 120. The top of the second ladder member 110 is connected to the bottom of the third ladder member 140, and the top of the second cover member 310 is connected to the bottom of the third cover member 330, thus forming a stable protection. The bottom of the first ladder member 120 is connected to the second ladder member 110, and the bottom of the first cover member 320 is connected to the top of the second cover member 310, thus forming a stable protection. It can be understood that the number of third ladder members 140 can be flexibly adjusted according to the height of the building to adapt to different application scenarios. In some climbing scenarios with a relatively small height, the first ladder member 120 can also be directly connected to the second ladder member 110 without the need for a third ladder member 140 in between.

[0034] In some embodiments of this utility model, such as Figures 1 to 8 As shown, the first cover component 320, the second cover component 310, and the third cover component 330 are all cage hoops. The cage hoops are made of flat steel. Flat steel has a certain strength and toughness, and can withstand external impact to ensure the safety of climbers. The first cover component 320 can be integrally formed by bending and shaping or welding and fixing processes. The integral forming method can enhance the structural stability.

[0035] Furthermore, in some embodiments of this utility model, the first cover 320 can also be formed by splicing two symmetrically arranged cage hoops together with fasteners. The first cover 320 can be disassembled into independent components during transportation, effectively reducing the transportation volume, and can be quickly assembled during installation. The modular structure facilitates disassembly and maintenance, improving installation flexibility. The formation methods of the second cover 310 and the third cover 330 are the same as those of the first cover 320, and will not be repeated here.

[0036] In some embodiments of this utility model, such as Figure 9 As shown, the ladder 200 includes an inclined fourth ladder member 210 and a horizontally positioned connecting platform 220. The inclined design reduces the concentrated stress at the connection between the ladder 200 and the platform 130, enhances structural stability, and allows for flexible installation by avoiding obstacles such as pipes and cable trays. The fourth ladder member 210 is equipped with a step, and handrails are provided around the fourth ladder member 210 and the connecting platform 220. The bottom of the handrails is fixedly connected to the fourth ladder member 210 and the connecting platform 220 by fasteners, which improves the safety performance of the ladder 200.

[0037] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the climbing ladder assembly 100 includes multiple fasteners 170. The fasteners 170 can be made of high-strength alloy steel, stainless steel, or aluminum alloy, and possess certain strength, corrosion resistance, and wear resistance. Multiple first connecting holes 171 are spaced apart along the length of each fastener 170. Each ladder has multiple second connecting holes 160, which correspond one-to-one with the first connecting holes 171. Adjacent ladders are fixedly connected via the fasteners 170, thus ensuring the stability of the connection.

[0038] Specifically, there are four first connecting holes 171. Two second connecting holes 160 are provided at the bottom of the first ladder member 120, and two second connecting holes 160 are provided at the top of the third ladder member 140. The two first connecting holes 171 on the upper side of the fixing member 170 correspond to the two second connecting holes 160 of the first ladder member 120, and the two first connecting holes 171 on the lower side of the fixing member 170 correspond to the two second connecting holes 160 of the third ladder member 140. The fixing member 170 cooperates with the fastener to fix the first ladder member 120 and the third ladder member 140 together. The connection method between the second ladder member 110 and the third ladder member 140 is the same as that between the first ladder member 120 and the third ladder member 140, and the connection method between the second ladder members 110 is also the same as that between the first ladder member 120 and the third ladder member 140.

[0039] In some embodiments of this utility model, the surface of the climbing ladder assembly 100 has an anti-corrosion coating. The anti-corrosion coating may be a hot-dip galvanized coating, an epoxy zinc-rich primer coating, or a polyurethane coating, etc., which can effectively isolate the contact between air, moisture and the metal substrate, and has a certain degree of wear resistance, can resist minor scratches in daily use, reduce the risk of corrosion caused by coating damage, and enhance the service life of the climbing ladder assembly 100.

[0040] In some embodiments of this utility model, such as Figures 3 to 5 As shown, the tread surface of ladder 200 is provided with anti-slip texture, and the tread surface of platform 130 is also provided with anti-slip texture. By increasing the roughness of the tread surface, friction is improved to prevent climbers from slipping while walking or climbing, thereby improving the safety performance of the multi-directional spliced ​​straight ladder.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
