Description

Technical Field

[0001] This utility model relates to a vertical take-off and landing platform for aircraft, belonging to the technical field of aircraft take-off and landing platforms. Background Technology

[0002] Currently, with the rapid development of the low-altitude economy, it has become possible to travel by short-distance small helicopters. Using drones for cargo delivery services such as express delivery and medical supply transportation has also become more convenient and efficient. Building platform structures that can accommodate the take-off and landing of small helicopters and drones is an indispensable infrastructure guarantee for realizing low-altitude flight.

[0003] Based on the environmental requirements of vertical takeoff and landing (VTOL) aircraft, not only is a landing platform necessary, but also the absence of any obstructions above it. Especially in urban environments, the landing platform typically needs to be 10 meters above the ground, which can be achieved by elevating the platform using a building. This building usually uses its roof platform as the landing platform. Since regulations require that no area within at least 3 meters of the VTOL aircraft be more than 25 centimeters above the landing plane, fencing around the landing platform is not feasible. This necessitates a sufficiently large landing platform to accommodate small helicopters and drones, while also considering the safety of operators working at height. This places demands on the roof platform of the building, requiring not only a landing platform sufficient for parking but also a safety platform on its outer side for operators working at height. While simply making the building large enough would naturally create a large enough roof platform that meets both parking and operator safety requirements, this approach is uneconomical and, in some cases, limited by ground space constraints. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a vertical take-off and landing platform for aircraft.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A vertical take-off and landing aircraft platform includes a platform body installed on the top of a building, at least a portion of the exterior facade of the building is a glass curtain wall, the building is provided with columns, and the platform body is installed on the columns; the platform body includes a platform main surface and a platform outer surface, the outer contour of the platform main surface is consistent with the outer contour of the building, and at least one section of the outer contour of the platform main surface is provided with the platform outer surface; The bottom of the platform's outer surface is provided with a cantilever beam, which corresponds to and is connected to the column. The outer perimeter of the glass curtain wall is also provided with a suspended purlin, which is connected to the cantilever beam or column via a lower hanging column. A diagonal brace is provided between the cantilever beam and the suspended purlin.

[0006] The beneficial effects of this utility model are: the platform body is located on the top of the building. The platform body not only has a main platform surface, but also has an extension on the top of the building to form an outer platform surface, which effectively expands the usable space on the top of the building. This not only meets the parking requirements of small helicopters and drones, but also provides a safe activity area for the main platform surface through the outer platform surface. The platform's main surface aligns with the building's outer contour, eliminating the need to enlarge the building's base dimensions and resolving the issues of uneconomical expansion and space constraints. The platform's outer surface is securely connected to the columns via cantilever beams. However, due to the presence of the glass curtain wall on the building, the lower part of the newly added outer surface cannot be directly connected to the existing structural columns. Therefore, suspended purlins, lower columns, and diagonal bracing are added around the glass curtain wall. The suspended purlins are connected to the cantilever beams via the lower columns, and the diagonal bracing increases the connection strength between the suspended purlins, cantilever beams, and lower columns, making the connection between the suspended purlins and cantilever beams more reliable. The combination of diagonal bracing, lower columns, and suspended purlins does not damage the original glass curtain wall on the building and provides support for the lower part of the newly added outer surface. This invention features a simple structure, achieving aesthetic appeal, aircraft take-off and landing, and safe operation for high-altitude workers without requiring a larger building or damaging the original building facade, while also significantly reducing construction costs.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, a reinforcing rod is provided between the lower hanging column and the suspension purlin.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the reinforcing rod can enhance the connection strength between the lower hanging column and the suspension purlin, ensure the stable load-bearing capacity of the suspension purlin, and enable the lower part of the platform extension surface to be shaped without damaging the original glass curtain wall.

[0010] Furthermore, there are two reinforcing rods, which are symmetrically arranged on both sides of the lower hanging column.

[0011] The beneficial effect of adopting the above-mentioned further solution is that a reinforcing rod is provided on each side of the lower hanging column, the force between the lower hanging column and the suspension purlin is more balanced, the support stability of the platform's outer surface is enhanced, and a more reliable guarantee is provided for the safety of the platform body.

[0012] Furthermore, the platform's outer surface is formed by overlapping the main surface of the platform.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the outer surface of the platform is connected to the main surface of the platform by cantilever beams, thereby expanding the overall area of ​​the platform body and providing a more spacious platform space for the safe activity area of ​​vertical take-off and landing aircraft and operators working at heights.

[0014] Furthermore, the surface of the platform's outer extension is no more than 25 centimeters higher than the surface of the platform's main body.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, as the landing platform of the vertical take-off and landing aircraft, according to safety regulations, no buildings higher than 25 centimeters above the surface of the landing platform are allowed within a distance of at least 3 meters around the aircraft's take-off and landing. Therefore, guardrails are not allowed to be set up around the main surface of the platform. However, there will be safety hazards when operators work at height on the platform body. The addition of the outer surface of the platform can meet the safety requirements of operators working at height on the main surface of the platform.

[0016] Furthermore, the building body is provided with a maintenance layer, and an elevator platform for aircraft transfer is provided between the platform body and the maintenance layer. The platform body is provided with an elevator shaft for the use of the elevator platform.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the maintenance layer can maintain and service the vertical take-off and landing aircraft. When the aircraft needs repair or maintenance, it can be transferred from the platform body to the maintenance layer through the elevator platform and elevator shaft, making it convenient for the aircraft to be maintained indoors.

[0018] Furthermore, the top of the building is provided with multiple support beams for supporting the main surface of the platform, and the support beams are connected to the columns.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the setting of multiple support beams can effectively distribute the load borne by the main surface of the platform, enhance the structural stability of the main surface of the platform, and ensure the safety of the vertical take-off and landing aircraft during take-off and landing.

[0020] Furthermore, a roof panel is provided on the support beam, the roof panel includes a plurality of open-type buckle plates, the open-type buckle plates are connected to the support beam, and adjacent open-type buckle plates are connected to each other.

[0021] The advantages of adopting the above-mentioned further solution are that the supporting beam and multiple open-type buckle plates have strong load-bearing capacity, which can meet the high load structural strength requirements of the main surface of the platform. The self-weight is small, the open-type buckle plates can be assembled on site, adjacent open-type buckle plates can be welded, and the welding between the supporting beam and the open-type buckle plates eliminates the need for the traditional concrete pouring process, which simplifies the construction process and greatly shortens the construction cycle of the roof structure.

[0022] Furthermore, the open-type buckle is a U-shaped structure with its closed surface serving as the bearing surface. One side of the open-type buckle is provided with an outward hook, and the other side is provided with an inward flange. The outward hook can accommodate the inward flange of the adjacent open-type buckle, and the adjacent open-type buckles are fastened together.

[0023] The beneficial effects of adopting the above-mentioned further solution are that the U-shaped structure further enhances the support strength of the open-type buckle panel, ensuring the stability of the roof panel. The inner flange can be placed inside the outer hook of the adjacent open-type buckle panel, and the interlocking of the outer hook and the inner flange facilitates the splicing between adjacent open-type buckle panels, making subsequent spot welding easier. The connection between adjacent open-type buckle panels is stable, effectively enhancing the stability and reliability of the roof panel. This type of roof panel is easy to install and can significantly shorten the construction cycle of the roof structure.

[0024] Furthermore, the surface of the roof panel is provided with a waterproof layer structure.

[0025] The beneficial effect of adopting the above-mentioned further solution is that a waterproof layer can be set on the roof panel, followed by a polyurethane mesh layer, and finally another waterproof layer. The double waterproof layer and the polyurethane mesh layer in between enhance the waterproof performance of the roof structure. The addition of the polyurethane mesh layer improves the toughness and durability of the waterproof layer and extends the service life of the roof structure. Attached Figure Description

[0027] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0028] like Figures 1-9 As shown, a vertical takeoff and landing (VTOL) aircraft landing platform includes a platform body mounted on top of a building 12. At least a portion of the exterior facade of the building 12 is a glass curtain wall 14. Columns 13 are provided on the building 12, and the platform body is mounted on the columns 13. The platform body includes a platform main surface 1 and a platform outer extension surface 2. The outer contour of the platform main surface 1 is consistent with the outer contour of the building 12, and at least one section of the outer contour of the platform main surface 1 is provided with the platform outer extension surface 2. The bottom of the platform extension surface 2 is provided with a cantilever beam 3, which corresponds to the position of the column 13 and is connected to the column 13. The outer periphery of the glass curtain wall 14 is also provided with a suspension purlin 4, which is connected to the cantilever beam 3 or the column 13 through a lower hanging column 5. A diagonal brace 6 is provided between the cantilever beam 3 and the suspension purlin 4.

[0029] A reinforcing rod 7 is provided between the lower hanging column 5 and the suspension purlin 4. The reinforcing rod 7 can enhance the connection strength between the lower hanging column 5 and the suspension purlin 4, ensure the stable load-bearing capacity of the platform's outer extension surface 2, make the planar outer extension surface more stable and reliable, and provide a solid guarantee for the safety of the platform body.

[0030] Two reinforcing rods 7 are symmetrically arranged on both sides of the lower hanging column 5. With one reinforcing rod 7 on each side of the lower hanging column 5, the force between the lower hanging column 5 and the suspension purlin 4 is more balanced, enhancing the support stability of the platform's outer surface 2 and providing a more reliable guarantee for the safety of the platform body.

[0031] The platform extension surface 2 is formed by overlapping the platform main surface 1. The platform extension surface 2 overlaps with the platform main surface 1 using cantilever beams 3, thereby increasing the overall area of ​​the platform body and providing a more spacious platform space for the safe operation area of ​​vertical take-off and landing aircraft and operators working at heights.

[0032] The surface of the platform's outer extension 2 is no more than 25 centimeters higher than the surface of the platform's main body 1. As the landing platform for a vertical takeoff and landing aircraft, the main body 1 is required to have no buildings exceeding 25 centimeters in height within a 3-meter radius of the aircraft's landing and takeoff area, according to safety regulations. Therefore, guardrails are not permitted around the main body 1. This creates a safety hazard for operators working at height on the platform. The addition of the outer extension 2 ensures the safety of operators working at height on the main body 1.

[0033] The building 12 contains a maintenance layer, and an elevator platform for aircraft transfer is provided between the platform body and the maintenance layer. The platform body is equipped with an elevator shaft 8 for the elevator platform. The maintenance layer can be used for the maintenance and upkeep of vertical takeoff and landing aircraft. When the aircraft needs repair or maintenance, it can be transferred from the platform body to the maintenance layer via the elevator platform and elevator shaft 8, facilitating indoor maintenance work.

[0034] The top of the building 12 is provided with multiple support beams 9 to support the main surface 1 of the platform, and the support beams 9 are connected to the columns 13. The arrangement of multiple support beams 9 can effectively distribute the load borne by the main surface of the platform, enhance the structural stability of the main surface 1 of the platform, and ensure the safety of the vertical take-off and landing aircraft during take-off and landing.

[0035] The support beam 9 located at the elevator shaft 8 includes a crossbeam, a longitudinal beam, and an inclined beam connecting the crossbeam and the longitudinal beam. The crossbeam is located on the front and rear sides of the elevator shaft 8, and the longitudinal beam is located on the left and right sides of the elevator shaft 8. The cooperation of the crossbeam, longitudinal beam, and inclined beam ensures that the elevator platform's lifting and lowering will not interfere with the lifting and lowering of the elevator shaft, and forms a stable support structure at the elevator shaft 8, greatly enhancing the structural strength of the elevator shaft 8 and further improving the safety and stability of the vertical take-off and landing aircraft platform.

[0036] A roof panel is mounted on the supporting beam 9. The roof panel includes multiple open-type snap-fit ​​panels 10, which are connected to the supporting beam 9. Adjacent open-type snap-fit ​​panels 10 are also connected to each other. The supporting beam 9 and the multiple open-type snap-fit ​​panels 10 have a strong load-bearing capacity, which can meet the high load structural strength requirements of the platform's main surface 1. The panel is lightweight, and the open-type snap-fit ​​panels 10 can be assembled on-site. Adjacent open-type snap-fit ​​panels 10 can be welded together, and the supporting beam 9 can be welded to the open-type snap-fit ​​panels 10. This eliminates the need for traditional concrete pouring, simplifies the construction process, and greatly shortens the construction cycle of the roof structure.

[0037] The open-type buckle panel 10 has a U-shaped structure, with its closed surface being the load-bearing surface 101. One side of the open-type buckle panel 10 has an outward-facing hook 102, and the other side has an inward-facing flange 103. The outward-facing hook 102 can accommodate the inward-facing flange 103 of an adjacent open-type buckle panel, allowing adjacent open-type buckle panels 10 to be fastened together. The U-shaped structure further enhances the support strength of the open-type buckle panel 10, ensuring the stability of the roof panel. The inward-facing flange 103 can be placed within the outward-facing hook 102 of an adjacent open-type buckle panel 10. The fastening of the outward-facing hook 102 and the inward-facing flange 103 facilitates splicing between adjacent open-type buckle panels 10, making subsequent spot welding convenient. The connection between adjacent open-type buckle panels 10 is stable, effectively enhancing the stability and reliability of the roof panel. This type of roof panel is easy to install and can significantly shorten the construction cycle of the roof structure.

[0038] The surface of the roof panel is provided with a waterproof layer structure 11. A waterproof layer can be set on the roof panel, followed by a polyurethane mesh layer, and finally another waterproof layer. The double waterproof layer and the polyurethane mesh layer in between enhance the waterproof performance of the roof structure. The addition of the polyurethane mesh layer improves the toughness and durability of the waterproof layer and extends the service life of the roof structure.

[0039] The platform body of this utility model is located on the top of the building 12. The platform body not only has a main platform surface 1, but also an extension surface 2 is formed on the top of the building 12. This effectively expands the usable space on the top of the building 12, which not only meets the parking requirements of small helicopters and drones, but also provides a safe operating and activity area for the main platform surface 1 through the platform extension surface 2. The main surface 1 of the platform is consistent with the outer contour of the building body 12. The bottom dimension of the building body 12 does not need to be enlarged, and the building body 12 does not need to be made bigger. The building body 12 only needs to be able to stably support the platform body, which can solve the problem that enlarging the building body 12 is uneconomical and limited by space. The outer surface 2 of the platform forms an extended platform. Through the stable connection between the cantilever beam 3 and the column 13, a suspension purlin 4 and diagonal brace 6 structure are added to the outer perimeter of the glass curtain wall 14. The suspension purlin 4 is connected to the cantilever beam 3 through the lower hanging column 5. The diagonal brace 6 can increase the connection strength between the suspension purlin 4 and the cantilever beam 3, ensure the load-bearing capacity and safety of the outer surface 2 of the platform, and achieve stable support for the outer surface 2 of the platform, thereby meeting the safety requirements of operators working at height.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
