[0030] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, in the absence of conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] Example 1

[0032] like Figure 3 As shown, a modular composite plate 1 of the utility model comprises a metal brazing plate 1-1 and a metal reinforcing plate 1-2 at least arranged on one side of the metal brazing plate 1-1.

[0033] Specifically, a metal reinforcing plate 1 - 2 is disposed on each of the two sides of the metal brazing plate 1 - 1 ; and metal pressure strips 1 - 3 are disposed around the modular composite plate 1 .

[0034] like Figure 4 As shown in FIG. 1 , as a specific embodiment, the metal bead 1-3 is provided with a first bead insertion protrusion 1-31 for inserting into the first side groove 1-11 and a second bead insertion protrusion 1-32 for inserting into the second side groove 1-12. Figure 5-6 As shown, the metal brazing plate 1-1 is provided with a first side groove 1-11 around it; the modular composite plate 1 is surrounded by two metal reinforcing plates 1-2 and the metal brazing plate 1-1 to form a second side groove 1-12.

[0035] In order to meet the requirements of light weight, large load-bearing capacity and impact resistance, the modular composite board 1 uses the metal brazing plate 1-1 as the base plate, which has the advantages of light weight, large load-bearing capacity and impact resistance. However, after the metal brazing plate 1-1 is brazed, the strength of the material will decrease.

[0036] To further improve the strength, rigidity and bearing capacity of the metal brazing plate, metal reinforcing plates 1-2 are added on both sides of the metal brazing plate 1-1, and the metal reinforcing plates 1-2 maintain the high strength performance of the metal plate in the rolled state. To prevent slipping, the metal reinforcing plates 1-2 can be made of anti-skid metal plates.

[0037] In order to increase the bearing capacity around the metal brazing plate 1 - 1 , metal pressure strips 1 - 3 are arranged around the modular composite plate 1 .

[0038] The modular composite plate 1 inherits the superior properties of the metal brazing plate and the rolled metal plate, and while meeting the lightweight requirements, achieves a significant increase in surface strength, solving the problem of low strength of the metal brazing plate after welding.

[0039] The metal brazing plate 1-1 is provided with a first side groove 1-11 on all sides, and the modular composite plate 1 is surrounded by two metal reinforcing plates 1-2 and the metal brazing plate 1-1 to form a second side groove 1-12;

[0040] Among them, the metal brazing plate 1-1 uses patent number 2021220133694, and the patent name is: a decking plate in a stackable combination pallet with stable transportation, the decking plate has a three-layer structure, the middle layer is a honeycomb core, and the upper and lower plates are fixedly connected on both sides of the honeycomb core. The upper and lower plates are both aluminum plates, and the honeycomb core is a metal honeycomb core. The lower aluminum plate, the metal honeycomb core and the upper aluminum plate are laid in a bottom-up order to form a three-layer structure, and then placed in a heat treatment furnace for brazing and fixing.

[0041] Example 2

[0042] On the basis of Example 1, Figure 1 As shown, the present application provides a specific embodiment of a modular quick-disassembly and assembly apron, wherein the modular quick-disassembly and assembly apron comprises a plurality of square modular composite panels 1 assembled together, wherein the modular composite panels 1 are provided with a connecting seat 2 for fixing the two modular composite panels 1 by a locking buckle 3 on at least one side of the modular composite panel 1 connected thereto.

[0043] When in use, the number of modular composite panels 1 to be spliced ​​is selected according to the size of the apron required by the aircraft, which may be 2, 4, 9 or more.

[0044] In the prior art, aluminum alloy profiles or polymer materials (fiber reinforced resin) are generally used as road panels, and threaded or latched fittings are used to achieve assembly and connection. Firstly, aluminum alloy profiles or polymer materials (fiber reinforced resin) are used as road panels, which are limited by the characteristics of the materials themselves and will result in insufficient load-bearing capacity. At the same time, they are not conducive to multiple disassembly and assembly. Secondly, threaded or latched fittings are used to achieve assembly and connection, which makes disassembly more complicated and is prone to increased difficulty in disassembly due to deformation under stress.

[0045] like Figure 2 As shown, in order to solve the problem of rapid assembly, as a specific implementation scheme, the connecting seat 2 includes a locking hole 2 - 1 for locking two adjacent modular composite panels 1 when the locking buckle 3 is inserted.

[0046] Specifically, the locking hole 2-1 of the connection seat 2 is provided with a locking portion 2-4 for rotationally locking the insertion pin 3-1 after insertion. Figure 2 As shown, the connecting seat 2 includes an edge sealing portion 2-2 and a locking hole seat 2-3; the locking hole 2-1 is formed on the locking hole seat 2-3; the edge sealing portion 2-2 is provided with a first edge sealing insertion protrusion 2-21 for inserting into the first edge groove 1-11 and a second edge sealing insertion protrusion 2-22 for inserting into the second edge groove 1-12.

[0047] The lock hole 2-1 may have various forms, such as a "convex" lock hole, etc. The present application provides a specific implementation of the lock hole 2-1, such as Figure 2 In the L-shaped lock hole shown in the figure, the lock hole 2-1 has a protruding lock portion 2-4, which can meet the requirement that the insertion pin 3-1 can be rotated and locked at the position where the lock portion 2-4 is located after being inserted.

[0048] As a specific implementation, the lock buckle 3 includes an insertion pin 3-1 for inserting into the lock hole 2-1 of the adjacent connection seat 2. As a specific implementation of the lock buckle 3, Figure 7 As shown in a-7b, the end of the insertion pin 3-1 is provided with a locking protrusion 3-2 for use with the locking portion 2-4 for rotational locking after the insertion pin 3-1 is inserted into the lock hole 2-1. The lock buckle 3 also includes a rotating portion 3-3, and the insertion pin 3-1 is fixedly connected to the rotating portion 3-3. When in use, the rotating portion 3-3 is rotated to determine whether the locking protrusion 3-2 is engaged with the locking portion 2-4, thereby achieving the locking of the lock buckle 3 or unscrewing and removing it from the lock hole 2-1.

[0049] When in use, there can be a variety of combinations of the connection seats 2 according to the number of assembled modular composite panels 1. For example, when two modular composite panels 1 are assembled, two adjacent connection seats 2 are spliced ​​to form a semicircular structure. Accordingly, the lock 3 also has a semicircular structure adapted to the two connection seats 2. Figure 8 As shown, if four modular composite panels 1 are assembled, adjacent connection seats 2 are spliced ​​to form a circular structure, and accordingly, the lock buckle 3 also has a circular structure adapted to the four connection seats 2. The present application provides a specific implementation of the connection seat 2, and the connection seat 2 is arranged at the four corners of the modular composite panel 1, and in actual application scenarios, it can also be arranged on the straight edge of the modular composite panel 1, and the setting position can be selected according to the changes in the application scenario.

[0050] like Figure 8-9 As shown, the modular quick-disassembly apron of the present application also includes a step buffer pad 4 provided on the outer edge of the outermost modular composite panel 1 when multiple modular composite panels 1 are assembled to provide a slope buffer for the apron. Here, the outer edge refers to Figure 4 The outer boundaries of multiple modular composite panels 1 in the assembled state.

[0051] Specifically, the present application provides a specific embodiment of a step buffer pad 4, wherein the step buffer pad 4 includes a straight-edge step buffer pad 4-1 and a corner step buffer pad 4-2 for forming an enclosed area; the step buffer pad 4 is provided with a pad connecting seat 5 which is fixed to the adjacent modular composite panel 1 by a lock 3.

[0052] The setting position of the pad connecting seat 5 on the step buffer pad 4 includes the following situations:

[0053] 1. If Fig.10 As shown, a pad connecting seat 5 is provided on the inner corners of both ends of the straight-edge step buffer pad 4-1. At this time, the turning angle of the pad connecting seat 5 is 90°. When splicing, the two pad connecting seats 5 and the two connecting seats 2 are spliced ​​together to form a circular splicing portion;

[0054] 2. If Fig.11 As shown, a pad connecting seat 5 is provided in the middle of the straight-edge step buffer pad 4-1. At this time, the rotation angle of the pad connecting seat 5 is 180°. When splicing, one pad connecting seat 5 and two connecting seats 2 are spliced ​​together to form a circular splicing portion;

[0055] 3. If Fig.12 As shown, a pad connecting seat 5 is provided on the inner corner side of the corner step buffer pad 4-2. At this time, the rotation angle of the pad connecting seat 5 is 270°. When splicing, a pad connecting seat 5 and a connecting seat 2 are spliced ​​together to form a second circular splicing part.

[0056] On the basis of the above solution, the setting position of the pad connector 5 on the step buffer pad 4 can be adaptively selected according to the number of modular composite panels 1 to be spliced, while ensuring stability.

[0057] The assembly process of the entire apron is to lay the modular composite board 1 and the step buffer pad 4 in place, and then twist the lock 3 at the corner joint to the corresponding position. When disassembling, the lock 3 is twisted and removed, and the modular composite board 1 and the step buffer pad 4 can be transported and packed; the entire disassembly and assembly process is fast, efficient, and convenient to use.

[0058] The helipad of the utility model adopts modular composite panels, connecting seats and step buffer pads during assembly. The entire helipad can be quickly and conveniently assembled and disassembled, and is not prone to the problem of unchanged disassembly due to deformation during use. At the same time, each component of the helipad is light and high-strength, meeting the requirements of manual field transportation. In addition, the helipad has a strong carrying capacity, which not only meets the parking requirements of low-altitude aircraft such as helicopters, but also meets the requirements of engineering vehicles getting on and off the platform, effectively improving the efficiency of field operations.

[0059] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
