Description

Technical Field

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

[0002] The low-altitude economy is a comprehensive new economic form that takes civilian manned and unmanned aircraft as the main body and low-altitude flight activities in multiple scenarios such as carrying people, cargo and other operations as the driving force, and promotes the integrated development of commercial activities or public service sectors.

[0003] With the booming development of the low-altitude economy and the continuous expansion of its application scenarios, short-haul helicopter travel has become increasingly common. Meanwhile, the use of drones for cargo delivery services such as express delivery and medical supply transport has become more convenient and efficient. This new mode of transportation requires the construction of platforms capable of vertical takeoff and landing for small manned helicopters and drones, which is an indispensable infrastructure guarantee for meeting the needs of low-altitude flight.

[0004] However, most vertical take-off and landing platforms currently used for manned or unmanned aerial vehicles adopt traditional reinforced concrete roof structures, which have obvious drawbacks: on the one hand, concrete itself is heavy, which puts higher demands on the building's load-bearing structure; on the other hand, concrete construction has a long cycle, which affects the progress of low-altitude economic infrastructure construction projects; in addition, platforms built with reinforced concrete also have the problem of environmental pollution. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a roof structure for vertical take-off and landing platforms.

[0006] The technical solution of this utility model to solve the above technical problems is as follows: A roof structure for a vertical take-off and landing platform includes a roof body, the roof body is set on the top of the building of the vertical take-off and landing platform, the roof body is reserved with a well opening for the aircraft lift platform, and the roof body includes a support beam and a roof panel set on the support beam. The roof panel includes a base plate and a protective layer disposed on top of the base plate. The base plate includes a plurality of open-type floor decks connected to each other. The protective layer includes a first waterproof layer, a polyurethane mesh layer and a second waterproof layer disposed sequentially on the base plate from the inside out.

[0007] The beneficial effects of this utility model are as follows: The roof panel adopts an open-type floor deck, and the combination of the supporting beam and multiple open-type floor decks provides strong load-bearing capacity, meeting the structural strength requirements of the roof structure under high loads, reducing the self-weight of the roof structure. The open-type floor deck can be assembled on-site, eliminating the need for traditional concrete pouring, simplifying the construction process, and greatly shortening the construction cycle of the roof structure, providing strong support for the rapid construction of low-altitude economic infrastructure. The double-layer waterproof layer and the intermediate polyurethane mesh layer enhance the waterproof performance of the roof structure. The addition of the polyurethane mesh layer improves the toughness and durability of the waterproof layer, extending the service life of the roof structure. This utility model has a simple structure, and the combination of the open-type floor deck and the supporting beam makes installation convenient and quick, meeting the load-bearing capacity requirements of the roof structure. The combination of the double-layer waterproof layer and the polyurethane mesh layer provides reliable waterproof protection for the roof. This roof structure generates less waste during construction, reducing environmental impact and conforming to the current concepts of green building and sustainable development.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the open-type floor deck has a U-shaped cross-section, and the closed surface of the open-type floor deck is the floor deck surface.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the open-type floor deck has a U-shaped structure, which can further enhance the support strength of the open-type floor deck, thereby better bearing the load generated during the take-off and landing of the aircraft and ensuring the stability of the roof structure.

[0011] Furthermore, the open-type floor deck is provided with an outward hook on one side and an inward flange on the other side. The outward hook of the open-type floor deck can accommodate the inward flange of the adjacent open-type floor deck, and the adjacent open-type floor decks are fastened together.

[0012] The beneficial effects of adopting the above-mentioned further solution are that the inner flange can be placed in the outer hook of the adjacent open-type floor deck, and the outer hook and the inner flange are connected by a snap fastener, which makes it convenient to connect the adjacent open-type floor decks and facilitates subsequent spot welding. The connection between the adjacent open-type floor decks is stable, which effectively enhances the stability and reliability of the roof structure. This snap fastening method is easy to install and can significantly shorten the construction cycle of the roof structure.

[0013] Furthermore, adjacent open-type floor decks are welded together, and the open-type floor decks are welded to the supporting beams.

[0014] The advantages of adopting the above-mentioned further solutions are that spot welding can be performed between the open-type floor deckings, and the open-type floor deckings near the supporting beams can be welded to the supporting beams. Welded connections enhance the overall stability and robustness of the roof structure, ensuring the safety and reliability of the vertical lift platform during use. In addition, welded connections have the advantages of simple construction and high efficiency, which can shorten the construction cycle and reduce construction costs.

[0015] Furthermore, the roof panel also includes a silicone PU surface layer, which is disposed on the outer surface of the second waterproof layer.

It can effectively bond with the waterproof layer, and its superior abrasion resistance can meet the needs of long-term high-frequency use and protect the waterproof surface layer. It can also buffer certain impacts, providing some protection for the roof panels and extending their service life. Furthermore, the silicone PU surface layer has good weather resistance and stability, resisting the erosion of natural factors such as ultraviolet rays and rainwater, and is not prone to aging or cracking, ensuring the stability and reliability of the roof panels in various harsh environments.

[0017] Furthermore, the support beam includes multiple straight beams disposed on the top of the building.

[0018] The advantages of adopting the above-mentioned further solution are that multiple straight beams can effectively distribute the pressure on the roof structure of the vertical lift platform, enhance the overall stability of the roof structure, and prevent the roof structure from deforming or being damaged when subjected to large loads, thus ensuring the safe use of the vertical lift platform. At the same time, straight beams are easy to process, facilitate construction and installation, and reduce costs.

[0019] Furthermore, the straight beam includes a crossbeam, a longitudinal beam, and a diagonal beam, and the crossbeam, longitudinal beam, and diagonal beam work together to form a stable support frame.

[0020] The beneficial effect of adopting the above-mentioned further solutions is that the roof structure, especially at the circular well opening, can adopt a combination of horizontal beams, longitudinal beams, and diagonal beams to form a more stable support frame, strengthen and stabilize the overall roof structure, prevent the roof structure from becoming unstable under complex stress conditions, and enable the roof structure to better adapt to the various loads generated by the vertical take-off and landing platform during take-off and landing, thereby further improving the safety and reliability of the roof structure.

[0021] Furthermore, the bottom of the substrate is provided with at least one anti-rust layer.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the anti-rust layer set on the bottom of the substrate can effectively prevent the substrate from rusting due to the humid environment or contact with water, extend the service life of the substrate, ensure the stability and safety of the roof structure, and ensure that the roof structure has good durability.

[0028] 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.

[0029] like Figures 1-9 As shown, a roof structure for a vertical take-off and landing platform includes a roof body, which is disposed on the top of the building body 3 of the vertical take-off and landing platform. The roof body has a pre-reserved well opening 4 for the aircraft lift platform. The roof body includes a support beam 1 and a roof panel 2 disposed on the support beam 1. The roof panel 2 includes a base plate and a protective layer 202 disposed on the top of the base plate. The base plate includes a plurality of open-type floor decks 201, which are connected to each other. The protective layer 202 includes a first waterproof layer 2021, a polyurethane mesh layer 2022 and a second waterproof layer 2023 disposed sequentially on the base plate from the inside to the outside.

[0030] The open-type floor deck 201 has a U-shaped cross-section, and the closed surface of the open-type floor deck 201 is the floor deck surface 2011. The U-shaped structure of the open-type floor deck 201 can further enhance the support strength of the open-type floor deck 201, better withstand the loads generated during the take-off and landing of the aircraft, and ensure the stability of the roof structure.

[0031] The open-type floor deck 201 has an outward-facing hook 2012 on one side and an inward-facing flange 2013 on the other side. The outward-facing hook 2012 of the open-type floor deck 201 can accommodate the inward-facing flange 2013 of the adjacent open-type floor deck 201, and the adjacent open-type floor decks 201 are interlocked. The inward-facing flange 2013 can be placed inside the outward-facing hook 2012 of the adjacent open-type floor deck 201. The interlocking of the outward-facing hook 2012 and the inward-facing flange 2013 makes the connection between adjacent open-type floor decks 201 convenient and facilitates subsequent spot welding. The connection between adjacent open-type floor decks 201 is stable, effectively enhancing the stability and reliability of the roof structure. This interlocking method is easy to install and can significantly shorten the construction cycle of the roof structure.

[0032] The adjacent open-type floor decking slabs 201 are welded together, and the open-type floor decking slabs 201 are welded to the supporting beam 1. Spot welding can be performed between the open-type floor decking slabs 201, and the open-type floor decking slabs 201 closest to the supporting beam 1 are welded to the supporting beam 1. Welded connections enhance the overall stability and robustness of the roof structure, ensuring the safety and reliability of the vertical lifting platform during use. Furthermore, welded connections offer advantages such as simple construction and high efficiency, shortening the construction period and reducing construction costs.

[0033] The roof panel 2 also includes a silicone PU surface layer 2024, which is disposed on the outer surface of the second waterproof layer 2023. The silicone PU surface layer possesses excellent comfort, superior wear resistance, good adhesion, ease of construction, technical stability, and environmental friendliness. It effectively bonds to the waterproof layer, and its superior wear resistance meets the needs of long-term high-frequency use and protects the waterproof layer. It also buffers some impact, providing a certain degree of protection for the roof panel and extending its service life. Furthermore, the silicone PU surface layer has good weather resistance and stability, resisting erosion from natural factors such as ultraviolet rays and rainwater, and is not prone to aging or cracking, ensuring the stability and reliability of the roof panel in various harsh environments.

[0034] The support beam 1 includes multiple straight beams installed on the top of the building body 3. These multiple straight beams effectively distribute the pressure on the roof structure of the vertical lift platform, enhancing the overall stability of the roof structure and preventing deformation or damage when subjected to large loads, thus ensuring the safe use of the vertical lift platform. Furthermore, the straight beams are easy to fabricate, facilitating construction and installation, and reducing costs.

[0035] The straight beams include a horizontal beam 101, a longitudinal beam 102, and a diagonal beam 103. The horizontal beam 101, longitudinal beam 102, and diagonal beam 103 work together to form a stable support frame. Especially at the circular well opening 4, the roof structure can utilize the combination of horizontal beam 101, longitudinal beam 102, and diagonal beam 103 to form a more robust support frame, strengthening and stabilizing the overall roof structure. This prevents instability under complex stress conditions, allowing the roof structure to better adapt to various loads generated during the vertical take-off and landing of the platform, further improving the safety and reliability of the roof structure.

[0036] The bottom of the substrate is also provided with at least one anti-rust layer. This anti-rust layer effectively prevents the substrate from corroding due to humidity or contact with water, extending its service life, ensuring the stability and safety of the roof structure, and guaranteeing its durability. In practice, anti-rust paint can be sprayed onto the bottom of the open-type floor deck 201. Depending on the required anti-rust performance, multiple coats of anti-rust paint can be applied to form the necessary anti-rust layer. For example, two coats of anti-rust paint can be sprayed onto the bottom of the open-type floor deck 201 to prevent rust from affecting the roof structure's service life.

[0037] A fireproof layer is also provided on the bottom of the substrate, and a rust-proof layer is disposed between the substrate and the fireproof layer. The fireproof layer on the surface of the rust-proof layer enhances the fire resistance of the roof structure and ensures its safety. After spraying rust-proof paint on the bottom of the open-type floor deck 201, a fire-retardant coating can be applied to form a fireproof layer, enabling the roof structure to meet fire safety requirements.

[0038] Both the first waterproof layer 2021 and the second waterproof layer 2023 are made of polyurethane waterproof coating. Polyurethane waterproof coating has excellent waterproof performance and adhesion, effectively preventing water penetration, protecting the roof structure from moisture erosion, and extending the roof's service life. At the same time, this coating also has good elasticity and weather resistance, adapting to the expansion and contraction of the roof due to temperature changes, ensuring the waterproof layer remains intact and effective for a long time.

[0039] The wellhead 4 for the aircraft landing platform is reserved for the aircraft landing platform. The aircraft lands on the aircraft landing platform, and the aircraft landing platform can carry the aircraft down into the building 3 for storage, maintenance, loading and unloading of cargo, etc. The building 3 of the vertical take-off and landing platform includes structural columns 301, and the support beam 1 is supported on the structural columns 301.

[0040] The roof panel 2 of this utility model adopts a non-cast open-type floor deck 201. The open-type floor deck 201 can be pre-cut to the corresponding size in the factory. On-site, it only needs to be assembled piece by piece. Every two to three panels can be welded to the support beam 1. Spot welding is performed between the open-type floor deck 201 panels. After the open-type floor deck 201 is laid, the bottom of the open-type floor deck 201 is first sprayed with anti-rust paint, if two coats can be sprayed, and then fireproof coating is sprayed. After that, the top of the open-type floor deck 201 is brushed with polyurethane waterproof coating twice to form a first waterproof layer 2021 and a second waterproof layer 2023. A polyurethane mesh layer 2022 is sandwiched between the waterproof layers. Finally, a silicone PU surface layer 2024 is applied. The support beam 1 and the open-type floor deck 201 are connected. The 201 floor decking has a strong load-bearing capacity, meeting the structural strength requirements of high-load roof structures while reducing the self-weight of the roof structure. The open-type 201 floor decking is assembled on-site, eliminating the need for traditional concrete pouring, simplifying the construction process and significantly shortening the construction cycle of the roof structure, providing strong support for the rapid construction of low-altitude economic infrastructure. The double-layer waterproofing layer and the intermediate polyurethane mesh layer 2022 enhance the waterproofing performance of the roof structure. The addition of the polyurethane mesh layer 2022 improves the toughness and durability of the waterproofing layer, extending the service life of the roof structure. This roof structure generates less waste during construction, reducing environmental impact and aligning with current green building and sustainable development concepts. This utility model provides a roof structure for vertical lifting platforms that is lightweight, quick to construct, environmentally friendly, has good integrity, and strong load-bearing capacity; the roof structure meets the requirements of corrosion resistance, fire resistance, waterproofing, wear resistance, and economy.
