Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] like Figures 1 to 7 As shown, this application provides a dedicated aluminum alloy deck structure for a helipad. The main deck body 100 includes a panel 10, a base 20, and a support plate 30. The support plate 30 is located in the middle of the panel 10 and the base 20. Two sets of pressure-reducing plates 40 are connected above the support plate 30 located in the middle of the panel 10 and the support plate 30. Positioning components 50 are disposed on both sides of the panel 10. The positioning components 50 include inserts 51 connected to one side of the panel 10, and inserts that are adapted to the inserts 51 are provided on the other side of the panel 10. The bottom of the panel 10 near the slot 52 is connected to a compression box 53, and the inside of the compression box 53 is provided with a moving hole 54, which passes through the panel 10 and connects to the slot 52. The inside of the moving hole 54 is provided with a positioning block 55, and the bottom of the positioning block 55 is connected to a linkage plate 56. The bottom of the linkage plate 56 is connected to a support spring 57 and a pull rod 58. The upper end of the insert 51 is provided with a 510. Anti-slip serrations 60 are provided at the upper end of the panel 10. Streamline grooves 70 are provided between two adjacent sets of anti-slip serrations 60.

[0035] By adopting the above technical scheme, the three groups of support plates 30 and the two groups of pressure relief plates 40 support the panel 10 and the base 20, and the three groups of support plates 30 can buffer the impact force when the panel 10 is impacted, and the deck main body 100 is in the form of an arch bridge structure, thereby increasing the strength of the deck main body 100.

[0036] During the installation of the plurality of deck main bodies 100, the user inserts the insertion bar 51 on the outer side of one group of panels 10 into the insertion slot 52 on the outer side of another group of panels 10, extrudes the rounded corner of the positioning block 55, and extrudes the positioning block 55 into the inside of the compression box 53 along the movement hole 54, thereby driving the linkage plate 56 to extrude the support spring 57 and the pull rod 58 to move downward along the inside of the positioning hole 59. When the end of the positioning block 55 is completely inserted into the inside of the movement hole 54, the insertion bar 51 can be smoothly inserted into the inside of the insertion slot 52. When the insertion bar 51 is positioned in the insertion slot 52, the linkage plate 56 is lifted up by the elastic potential energy of the plurality of support springs 57, and the positioning block 55 is indirectly lifted up into the inside of the insertion bar 51, thereby positioning the insertion bar 51 in the insertion slot 52 and ensuring the stable connection between the two deck main bodies 100. Then, the deck main body 100 is installed and fixed to the foundation through the bolt installation hole 80. During the assembly and use, the deck main bodies 100 are embedded and combined with each other, and each deck main body 100 is tightly combined to effectively prevent loosening and the occurrence of gaps.

[0037] It should be noted that the number of anti-skid sawteeth 60 is multiple, which can achieve the anti-skid effect. The streamline groove 70 has the functions of preventing water accumulation and sound absorption and noise reduction, thereby reducing the influence of the noise of the helicopter on the building. The unique arch bridge-like patent design structure makes the stress performance of the deck main body 100 more outstanding.

[0038] In an optional embodiment, the number of support plates 30 is three, and the middle support plate 30 and the two groups of pressure relief plates 40 are in an integrated structure, and the two groups of pressure relief plates 40 and the panel 10 are in an integrated structure, thereby improving the overall strength and relieving the defect that the helicopter landing is prone to hard impact.

[0039] In an optional embodiment, the included angle between the support plate 30 on any one side and the base 20 is between 60° and 70°, thereby conforming to the principle of dynamics and reducing the maximum dynamic load coefficient to 1.86, which is reduced by 38% compared with the domestic and foreign regulation of the dynamic load coefficient of 3.0. The impact load is greatly reduced, which is beneficial to the strength safety of the helipad and the supporting building and prolongs the service life of the helicopter.

[0040] In an optional embodiment, the height between the top of the panel 10 and the bottom of the base 20 is 120 cm, and the width of the panel 10 is 240 cm, which better conforms to the installation standard of the low-altitude helipad.

[0041] In an alternative embodiment, the upper end of the base 20 is provided with bolt mounting holes 80 for bolt fixation of the base 20, and the bolt mounting holes 80 pass through the middle part of the base 20, so as to facilitate fixation of the base 20 on the roof and ensure the installation strength.

[0042] In the embodiment, the length of the insertion strip 51 is equal to that of the panel 10, the moving holes 54 are in communication with the interior of the compression box 53, and the number of the moving holes 54 is three groups and is distributed in an array, the positioning blocks 55 are adapted to the moving holes 54, and the number of the positioning blocks 55 is opposite to that of the moving holes 54, and the side edge of the positioning blocks 55 away from the insertion strip 51 is provided with a round corner, so as to facilitate extrusion of the positioning blocks 55 during connection of the insertion strip 51 and the insertion slot 52, and the side edge of the positioning blocks 55 away from the round corner is a right angle structure after positioning between the positioning blocks 55 and the 510, so as to facilitate positioning and avoid extrusion between the positioning blocks 55 and the 510.

[0043] In an alternative embodiment, the bottom of the compression box 53 is provided with positioning holes 59 adapted to the pull rods 58, and the positioning holes 59 are in communication with the interior of the compression box 53, so as to facilitate disassembly between the insertion strip 51 and the insertion slot 52, and the linkage plate 56 drives the positioning blocks 55 to move downward along the interiors of the moving holes 54 and the 510 by pulling the pull rods 58 along the interiors of the positioning holes 59, so as to separate the positioning blocks 55 from the 510, and then disassemble the insertion strip 51 and the insertion slot 52, and further disassemble the two deck main bodies 100, which is convenient to operate, and only needs to insert for installation and only needs to pull the pull rods 58 for disassembly, so as to facilitate quick positioning between the two deck main bodies 100.

[0044] It should be noted that the deck main body 100 is a high-performance deck based on aluminum-magnesium alloy profiles, which is specially designed for helicopter take-off and landing in low-altitude economic industries;

[0045] It adopts lightweight and high-strength materials and a patented arch bridge structure, has a sawtooth anti-slip surface layer and a streamline groove body design, can effectively prevent water accumulation, reduce noise, and disperse impact load;

[0046] Through flexible dynamic optimization, the dynamic load coefficient is as low as 1.86 (38% lower than the industry standard), which significantly relieves the risk of hard impact and prolongs the service life of the helicopter;

[0047] The structure has the advantages of convenient construction and strong corrosion resistance, and is one of the core components of urban air transportation UAM infrastructure.

[0048] The aluminum alloy deck of the structure adopts A6061 material, has high strength and good corrosion resistance, and is weldable;

[0049] 6061 aluminum alloy takes magnesium and silicon as main alloying elements, forms Mg2Si phase, and in heat treatment state, Mg2Si is dissolved in aluminum to give the alloy artificial aging hardening characteristics;

[0050] Thus, the deck body 100 is very suitable as a structural element of an air-helicopter parking apron.
