[0033] Reference below Figure 1-Figure 5 The invention describes a box beam connection structure for a deck of an offshore vessel according to an embodiment of the invention.

[0034] like Figure 1-Figure 5 As shown, the box beam connection structure of the deck of an offshore engineering ship is applied at the connection between the deck 100 and the column 200 of the ship to improve the structural strength of the deck 100 and optimize the cargo capacity of the single deck 100. The ship includes multiple decks 100, and the decks 100 between the upper and lower layers are supported and connected by the columns 200.

[0035] The deck beam 110 and the longitudinal box beam 120 are respectively arranged under the deck 100. The deck beam 110 is laid along the lateral extension under the deck 100, and the longitudinal box beam 120 is laid along the longitudinal extension under the deck 100. The deck beam 110 and the longitudinal box beam 120 form a grid reinforcement structure, which is used to improve the fatigue strength and rigidity of the deck 100. The associated structures are effectively connected, and the structural forces of the deck 100 are effectively transmitted and distributed.

[0036] Among them, the deck longitudinal box beam 120 is respectively connected to the deck 100, the deck cross beam 110 and the column 200 to form a structural connection point, and the structural connection node 300 is used to enhance the structural strength of the deck 100 and the column 200, and effectively transfer the force between the connected components. Specifically, the structural connection points are distributed at the positions where the upper and lower ends of the column 200 are connected to the deck 100. Increasing the strength of the deck 100, on the existing structural form, increasing the structural strength of the deck 100, thereby increasing the cargo loading capacity of the ship. Reducing the construction cost, while effectively increasing the fatigue strength of the ship structure.

[0037] The transverse spacing of the deck beams 110 is a2, and the longitudinal spacing of the deck longitudinal box beams 120 is a1, the design value of a2 is 0.5-0.8m, and the design value of a1 is 1.5-3.2m. The height value of the column 200 is b1, and the design value of b1 is 2.5-3m, which is determined according to the ship design specifications.

[0038] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the deck cross beam 110 is made of steel structure profile, the deck longitudinal box beam 120 is made of steel structure box beam profile, and the column 200 is made of square steel pipe structure.

[0039] Specifically, the deck longitudinal box beam 120 adopts a combined steel structure box beam form, and the column 200 adopts a square steel pipe structure. The deck longitudinal box beam 120 is a stiffening material structure of the deck 100, and is effectively connected to the deck 100 and the deck beam 110. At the same time, the column 200 is designed under the deck longitudinal box beam 120 for supporting the structure, effectively supporting each layer of the deck 100, and effectively transmitting the force between each layer.

[0040] The deck cross beam 110, the deck longitudinal box beam 120 and the column 200 are made of classification society profiles and steel plates, and classification society A-grade steel materials are selected. The deck cross beam 110 is made of bulb flat steel profiles, the column 200 is made of square tube profiles, and the deck longitudinal box beam 120 is a box beam steel plate welded composite structure.

[0041] In some embodiments of the present invention, Figure 2-Figure 5 As shown, the deck longitudinal box girder 120 includes a longitudinal box girder face plate 121 and a longitudinal box girder web 122, and the longitudinal box girder face plate 121 and the longitudinal box girder web 122 are connected by fillet welding.

[0042] Specifically, the longitudinal box girder web 122 forms an effective fillet welding connection with the longitudinal box girder face plate 121 , while ensuring that the longitudinal box girder face plate 121 can effectively bear the end section of the column 200 .

[0043] In some embodiments of the present invention, Figure 2-Figure 5 As shown, the height of the longitudinal box beam web 122 is equal to the height of the deck beam 110. Specifically, the height of the longitudinal box beam web 122 is C1, where the height C1 is equal to the height of the profile deck beam 110, which can effectively control the height of the deck longitudinal box beam 120, thereby increasing the inter-layer clearance height of the deck 100 without changing the layer height, improving the inter-layer cargo space of the deck 100, and ensuring the safety value of the ship design without increasing the overall height of the ship. The height between the layers of the deck 100 is improved, thereby improving the inter-layer cargo utilization rate.

[0047] In some embodiments of the present invention, Figure 3-Figure 5 As shown, the structural connection node 300 is set at the connection between the column 200 and the deck 100. Specifically, the deck longitudinal box beam 120 is welded to the deck 100 to form a deck 100 stiffener structure, and is also welded to the end of the deck cross beam 110. The structural continuity of the structural connection node 300 is ensured, an effective grid stiffener connection structure is formed, and the strength of the deck 100 is effectively improved.

[0048] In some embodiments of the present invention, Figure 3-Figure 5 As shown, a column bottom pad 210 is provided at the position where the lower part of the column 200 is connected to the deck 100 . The column bottom pad 210 is used to increase the cross-sectional area of ​​the lower end of the column 200 and improve the force transmission path of the column 200 .

[0049] Specifically, the column bottom pad 210 designed at the lower end of the column 200 covers the deck 100, increasing the cross-sectional area of ​​the lower end of the column 200, which can ensure that the column 200 is effectively stressed.
