[0034] Reference below Figure 1-Figure 4 The present invention is described in detail with reference to a multi-purpose marine ship deck beam structure according to an embodiment of the present invention.

[0035] like Figure 1-Figure 4 As shown, the deck beam structure of the marine engineering multipurpose ship includes a lower deck cross beam 110, a lower deck longitudinal beam 120, an upper deck cross beam 130 and an upper deck longitudinal beam 140. The cross beam and the longitudinal beam are respectively arranged on the upper and lower sides of the deck 100. Specifically, the ship includes multiple decks 100, and the upper and lower adjacent decks 100 are supported and connected by columns 200.

[0036] The lower deck cross beam 110 is arranged below the deck 100, and the lower deck cross beam 110 extends to the position of the column 200. The lower deck longitudinal beam 120 is arranged below the deck 100, and the lower deck longitudinal beam 120 extends to the position of the column 200. The upper deck cross beam 130 is arranged above the deck 100, and the upper deck cross beam 130 extends to the position of the column 200. The upper deck longitudinal beam 140 is arranged above the deck 100, and the upper deck longitudinal beam 140 extends to the position of the column 200. The upper and lower sides of each deck 100 are provided with cross beams and longitudinal beams.

[0037] The lower deck cross beam 110 and the lower deck longitudinal beam 120 are arranged perpendicular to each other, and the upper deck cross beam 130 and the upper deck longitudinal beam 140 are arranged perpendicular to each other. The lower deck cross beam 110, the lower deck longitudinal beam 120, the upper deck cross beam 130 and the upper deck longitudinal beam 140 form a mesh reinforcement structure, and the position where the column 200 is connected to the deck 100 is connected and supports the upper and lower decks 100 through the mesh reinforcement structure, and the force is transmitted through the mesh reinforcement structure.

[0038] Specifically, mesh reinforcement structures are respectively arranged on the upper and lower layers of each deck 100 to enhance the structural strength of the deck 100 between the columns 200 and the deck 100, thereby improving the fatigue life of the ship structure. The design of the upper and lower beam structures effectively connects the associated structures, optimizes the force transmission between the structural members, and improves the force of the distribution structure of the deck 100. This enables a single deck 100 to carry more cargo and improves the space utilization of the deck 100.

[0039] The mesh reinforcement structure panel is welded to the web of the column 200 to form a lateral connection structure, which effectively increases the supporting contact surface of the side surface of the column 200 and effectively transfers the force between the decks 100 of each layer.

[0040] In some embodiments of the present invention, Figure 1-Figure 4 As shown, the lower deck cross beam 110, the lower deck longitudinal beam 120, the upper deck cross beam 130 and the upper deck longitudinal beam 140 all adopt the same bulb-flat steel structure.

[0041] Specifically, the deck 100 is supported by columns 200 between each layer, and the lower deck cross beam 110, the lower deck longitudinal beam 120, the upper deck cross beam 130, and the upper deck longitudinal beam 140 constitute the overall mesh reinforcement structure of the deck 100. The lower deck cross beam 110, the lower deck longitudinal beam 120, the upper deck cross beam 130, and the upper deck longitudinal beam 140 adopt a single steel structure profile specification, and use Class A steel materials of the classification society and bulb flat steel profiles to effectively transfer the forces between each layer of the deck 100.

[0042] In some embodiments of the present invention, Figure 1 and 3 As shown, a fence 300 is provided on the deck 100 , and the fence 300 is provided on the deck cross beam 130 and the deck longitudinal beam 140 .

[0043] Specifically, a fence 300 is designed and arranged on the surface of the deck 100, and the deck cross beam 130 and the deck longitudinal beam 140 are both the mesh reinforcement structure of the deck 100 and the structural base of the fence 300. The mesh reinforcement structure is a multifunctional beam structure of the deck 100. The deck longitudinal beam 140 and the deck cross beam 130 can also serve as the deck 100 surface fence structure and are connected to the fence 300 as a whole.

[0044] In some embodiments of the present invention, Figure 2 As shown, the spacing between adjacent under-deck beams 110 is 0.5m to 0.8m, and the spacing between adjacent upper-deck beams 130 is 0.5m to 0.8m. The transverse spacing between the under-deck beams 110 and the upper-deck beams 130 is a2, and the design value of a2 is 0.5 to 0.8m. Specifically, the spacing between the under-deck beams 110 and the upper-deck beams 130 is adjusted according to the scale of the ship deck 100.

[0045] In some embodiments of the present invention, Figure 2 As shown, the spacing between adjacent under-deck longitudinal beams 120 is 1.2m to 2.0m, and the spacing between adjacent upper-deck longitudinal beams 140 is 1.2m to 2.0m. The longitudinal spacing between the under-deck longitudinal beams 120 and the upper-deck longitudinal beams 140 is a1, and the design value of a1 is 1.2 to 2.0m. Specifically, the spacing between the under-deck longitudinal beams 120 and the upper-deck longitudinal beams 140 is adjusted according to the scale of the ship deck 100.

[0046] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the column 200 adopts a square steel pipe structure. Specifically, the column 200 is designed between the decks 100 as a supporting structure, and the material of the column 200 is a classification society profile and a steel plate. It can effectively support each layer of the deck 100 and effectively transfer the force between each layer.

[0047] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the upper and lower mesh reinforcement structures are respectively welded to the web of the column 200 to form a rigid structure and a lateral connection structure.

[0048] Specifically, the upper deck cross beam 130 and the upper deck longitudinal beam 140 are simultaneously connected and fixed to the lower end of the column 200 to form an overall rigid structure. The lower deck cross beam 110 and the lower deck longitudinal beam 120 are simultaneously connected and fixed to the lower end of the column 200 to form an overall rigid structure. The lower deck longitudinal beam 120 and the upper deck longitudinal beam 140 are respectively distributed above and below the deck 100, and the upper and lower positions of the structure correspond to each other. At the same time, the web of the longitudinal beam is respectively welded to the side of the web at the end of the column 200, which increases the welding contact area and correspondingly enhances its structural strength, which can ensure the force balance of the column 200.

[0049] In some embodiments of the present invention, Figure 1-3 As shown, the height of the column 200 is 2.5m to 3.0m, and the spacing between adjacent columns 200 is 1.5m to 3.2m. Specifically, the spacing between the columns 200 is a3, and the design value of a3 is 1.5 to 3.2m. The height value of the column 200 is b1, and the design value of b1 is 2.5 to 3m. The design value is determined according to the ship design specifications.

[0050] In some embodiments of the present invention, Figure 1-4 As shown, in response to the needs of special ship types, the deck 100 stiffener structure is designed to adopt an upper and lower beam structure, both of which are the main deck 100 stiffener structures, effectively connected to the deck 100, and at the same time can reduce the height of the stiffener structure, can provide more effective area of ​​the deck 100 and increase the height between decks 100, thereby providing a larger effective cargo area and space.

[0051] Under the condition that the height of deck 100 remains unchanged, the clearance height between deck 100 layers is directly increased to improve the cargo space between deck 100 layers, but the overall height of the ship is not increased, so as to ensure the safety value of the ship design.
