[0027] like Figures 1-3 As shown, this utility model applies to roll-formed elevator top panels, including a wall panel 1, an edge portion 2, and a reinforcing portion 3. The wall panel 1 is horizontally arranged, the edge portion 2 is located at both ends of the wall panel 1, and the reinforcing portion 3 is formed by a vertical recess in the wall panel 1. Figure 1 In this context, the reinforcing part 3 is formed by the upward indentation of the wall panel 1;

[0028] The edge portion 2 includes a first connecting plate 21 and a second connecting plate 22 that are connected to each other. One end of the first connecting plate 21 is connected to the wall panel 1, and the other end is connected to the second connecting plate 22. The first connecting plate 21 is provided with a plurality of punches (not shown in the figure).

[0029] A first rounded corner 211 is formed at the connection between the first connecting plate 21 and the wall panel 1, and a second rounded corner 221 is formed at the connection between the first connecting plate 21 and the second connecting plate 22.

[0030] A third rounded corner 311 is formed at the connection between the reinforcing part 3 and the wall panel 1, a reinforcing gap 31 is formed between the inner sidewalls of the reinforcing part, and a fourth rounded corner 312 is formed at the top of the reinforcing gap.

[0031] This invention is applicable to roll-formed elevator roof panels, simplifying the manufacturing process and improving production efficiency. The edge portion 2 facilitates connection with other components, the reinforcing portion 3 enhances the structural strength of the elevator roof panel, and the designs of the first rounded corner portion 211, the second rounded corner portion 221, the third rounded corner portion 311, and the fourth rounded corner portion 312 reduce stress concentration and extend service life. Using this invention for roll-formed elevator roof panels results in high production efficiency and high structural strength.

[0032] Regarding the specific arrangement of the first connecting plate 21 and the second connecting plate 22: The first connecting plate 21 is perpendicular to the wall panel 1, and the second connecting plate 22 is parallel to the wall panel;

[0033] One end of the second connecting plate 22 is connected to the first connecting plate 21, and the other end extends toward the center of the elevator top plate;

[0034] An edge groove is formed between the second connecting plate 22, the first connecting plate 21 and the wall panel 1;

[0035] An upward-opening groove is formed between the reinforcing part 3, the wall panel 1, and the edge part 2.

[0036] It should be noted that the design of the first connecting plate 21 being perpendicular to the wall panel 1 and the second connecting plate 22 being parallel to the wall panel 1 provides a simple connection structure and improves the stability and reliability of the connection. The edge groove is formed between the second connecting plate 22, the first connecting plate, and the wall panel 1, which can further enhance the strength of the edge portion 2. The cooperation between the edge groove and the wall panel groove can provide a space for components such as wiring pipes and ventilation pipes to pass through while maintaining structural strength.

[0037] Regarding the dimensions of the first connecting plate 21 and the second connecting plate 22, the ratio of the height H2 of the second connecting plate 22 to the height H1 of the first connecting plate 21 is 0.5-1.

[0038] The height H1 of the first connecting plate 21 is 20mm-30mm, and the height H2 of the second connecting plate 22 is 10mm-20mm;

[0039] Preferably, the height H1 of the first connecting plate 21 is 25mm, and the height H2 of the second connecting plate 22 is 15mm.

[0040] It should be noted that in the actual design, the height ratio of the second connecting plate 22 to the first connecting plate 21 needs to balance the mechanical properties and weight of the elevator roof panel, making it both lightweight and sturdy, adaptable to different installation requirements. The design of a height H1 of 25mm for the first connecting plate 21 and a height H2 of 15mm for the second connecting plate 22 ensures that the elevator roof panel maintains sufficient strength while being sufficiently lightweight, suitable for weight-sensitive applications.

[0041] Regarding the dimensions of the reinforcing part 3, its height is 15mm-35mm, and the height H3 of the reinforcing part 3 is designed according to different strength requirements.

[0042] Preferably, the height H3 of the reinforcing part 3 is 25mm. Setting the height H3 of the reinforcing part 3 to 25mm is equal to the height H1 of the first connecting plate 21, which is 25mm. This ensures the impact resistance of the elevator roof while keeping the top of the reinforcing part 3 at the same height as the top surface of the edge part 2, thereby enhancing the overall appearance of the elevator roof and improving its aesthetics.

[0043] Regarding the specific dimensions of the rounded corner treatment, the rounded corner radius R1 of the first rounded corner portion 211, the rounded corner radius R2 of the second rounded corner portion, and the rounded corner radius R3 of the third rounded corner portion are 3mm-5mm, preferably 3mm;

[0044] The rounded corner design reduces the sharpness of the elevator top plate edges, improving safety. At the same time, the rounded corner transition helps reduce stress concentration, enhances the durability of the structure, and extends its service life.

[0045] Regarding the dimensions of the reinforcing gap 31, the width D3 of the reinforcing gap 31 is 3mm-5mm, and the ratio of the radius R4 of the fourth rounded corner to the width D3 of the reinforcing gap is 0.3-0.7. Preferably, D3 = 3mm and R4 = 1.5mm.

[0046] It should be noted that the reinforcement 3 can improve the bending resistance of the elevator top plate, while the reinforcement gap 31 can improve the elasticity of the elevator top plate under bending moment. In actual manufacturing, D3 should be made as small as possible to reduce stress concentration and improve the overall rigidity and strength of the structure. Through the precise design of the fillet radius and the width D3 of the reinforcement gap 31, the mechanical properties of the elevator top plate are further optimized, ensuring the stability and durability of the elevator top plate under load and improving the fatigue resistance of the elevator top plate.

[0047] like Figure 4As shown, in terms of the overall dimensions of the elevator roof panel, the thickness of the elevator roof panel is 1.2mm-5mm, the width W is 300mm-500mm, and the length H is 1500mm-2500mm.

[0048] Preferably, the width W is 500mm and the length H is 2500mm. The thickness of the elevator top plate is generally 1.2mm, and the specific value depends on the material selection and design requirements. The size range of the elevator top plate is designed to be suitable for various elevator models, which improves the versatility and market adaptability of the product, while meeting the specific size requirements of different customers.

[0050] Adjacent elevator roof panels in the elevator roof panel system are connected by the first connecting plate 21, enabling rapid installation between elevator roof panels.

[0051] Preferably, regarding the specific connection method between adjacent elevator top panels, the perforations of the elevator top panel align with the perforations of the adjacent elevator top panels, allowing the fasteners to pass through the two perforations to fix the two adjacent elevator top panels.

[0052] The fasteners are bolts and nuts. The bolts pass through the punched holes in the two elevator roof panels in sequence and are then connected to the nuts to connect the two adjacent elevator roof panels. The design of punched joints and fastener connections provides a simple and effective way to fix elevator roof panels, ensuring the firmness and stability of the elevator roof panel connection. It also facilitates the disassembly and replacement of elevator roof panels, improving the flexibility and maintainability of the elevator roof panel system.

[0053] This invention is applicable to roll-formed elevator roof panels, simplifying the manufacturing process and improving production efficiency.
