DETAILED DESCRIPTION

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0025] The purpose of the present application is to provide an apron deck with good stability, large bearing capacity and large rigidity.

[0026] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0027] REFERENCE Figs. 1-2The disclosed apron deck in the embodiment comprises a first panel 1 and a second panel 2 arranged in parallel with each other, and the first panel 1 and the second panel 2 are connected by an X-shaped web, the X-shaped web comprises a first support plate 3 and a second support plate 4 connected in cross, the two ends of the first support plate 3 and the two ends of the second support plate 4 are connected to the first panel 1 and the second panel 2 respectively, the X-shaped web can disperse the load in the direction of the first support plate 3 and the second support plate 4, and can more efficiently resist multi-directional shear force such as wave impact or asymmetric load compared with unidirectional web; the cross structure forms a stable triangular grid, which can reduce the buckling risk of the X-shaped web under compression, improve the overall bending and torsional resistance of the apron deck, and improve the overall stiffness and bearing capacity of the apron deck; the cross nodes of the X-shaped web can disperse vibration energy, reduce the risk of resonance caused by the engine, waves or wind load, reduce fatigue damage, and have good stability; the two sides of the X-shaped web are respectively provided with a third support plate 5 and a fourth support plate 6, the two ends of the third support plate 5 and the two ends of the fourth support plate 6 are connected to the first panel 1 and the second panel 2 respectively, and the third support plate 5 and the fourth support plate 6 can absorb instantaneous impact through plastic deformation to effectively protect the main structure; the third support plate 5 is parallel to the first support plate 3, and the fourth support plate 6 is parallel to the second support plate 4, and by arranging the third support plate 5 and the fourth support plate 6 parallel to the first support plate 3 and the second support plate 4 respectively, the overall bending and torsional resistance of the apron deck can be further improved.

[0028] The width of the second panel 2 is smaller than the width of the first panel 1, since the third support plate 5 and the fourth support plate 6 are both inclined upward, the distance between the connection points of the third support plate 5 and the fourth support plate 6 and the second panel 2 is smaller than the distance between the connection points and the first panel 1, the width of the second panel 2 can be reduced to reduce the amount of material and save costs, and at the same time the weight of the apron deck is also reduced, facilitating the disassembly and maintenance of the apron deck.

[0029] The first panel 1 is respectively provided with a plug plate 8 and a groove 7 at both ends in the width direction, adjacent apron decks are inserted and connected through the plug plate 8 and the groove 7, the plug plate 8 and the groove 7 are convenient to insert and connect, and the rapid assembly and disassembly of the apron can be realized; in an embodiment, adjacent apron decks can also be spliced by bolt connection.

[0030] The intersection connection of the first support plate 3 and the second support plate 4 is integrally formed; the two ends of the first support plate 3 and the two ends of the second support plate 4 are integrally formed with the first panel 1 and the second panel 2 respectively; the two ends of the third support plate 5 and the two ends of the fourth support plate 6 are integrally formed with the first panel 1 and the second panel 2 respectively; the nodes are connected by integrally formed mode, which improves the connection strength of the apron deck; in an embodiment, the intersection connection of the first support plate 3 and the second support plate 4 can also be welded, and the other nodes can also be connected by bolts; in the embodiment, the thickness of the end of the support plate close to the panel gradually increases, which can further strengthen the connection strength of the nodes.

[0031] The end surface of the first panel 1 away from the second panel 2 is provided with an anti-skid groove, which can increase the friction between the helicopter and the first panel 1, and ensure the stable take-off and landing of the helicopter.

[0032] The end surface of the second panel 2 away from the first panel 1 is provided with an anti-skid groove, which can increase the friction between the second panel 2 and the main structure, and prevent the displacement of the apron deck when the helicopter takes off and lands.

[0033] The materials of the first panel 1, the second panel 2, the first support plate 3, the second support plate 4, the third support plate 5 and the fourth support plate 6 are all aluminum alloy. The light weight characteristics of aluminum alloy combined with the X-shaped web layout can make the structure light in weight while maintaining high strength. Even if the local web is damaged, the cross structure can still transfer the load through other paths, which improves the structural redundancy. At the same time, due to the high thermal expansion coefficient of aluminum alloy, the X-shaped web layout can offset the local thermal deformation through symmetry, reducing the stress concentration caused by temperature change.

[0034] The embodiment also includes an apron formed by splicing a plurality of the above apron decks.

[0036] The principles and implementation manners of the present application are described by using specific examples in the present application, and the above examples are only used for helping to understand the method of the present application and its core idea; meanwhile, for the general technical personnel in the art, according to the idea of the present application, the specific implementation manners and application ranges will be changed. In conclusion, the content of the present specification should not be understood as the limitation of the present application.
