Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a ship superstructure deck structure. Background Technology

[0002] Traditional passenger (roll-on / roll-off) ship superstructure deck structures generally employ conventional welded steel plate reinforcement structures. For example... Figure 1 As shown, the superstructure deck 30 includes plates 31 and stiffeners 32. Stiffeners 32, arranged at certain intervals, are welded below the plates 31. Stiffeners are typically made of flat steel, angle steel, or similar profiles, and are mostly made of ordinary carbon steel. This is not conducive to controlling the weight of the passenger (roll-on / roll-off) ship's top structure or the height of its center of gravity, negatively impacting stability. Even if lightweight aluminum alloy materials are used to control weight and center of gravity, significant deformation is more likely to occur during welding, damaging structural strength and severely affecting the flatness and overall appearance of the components.

[0003] Currently, the superstructure deck structure of passenger (roll-on) ships adopts a conventional welded plate reinforcement structure design, which has the following problems:

[0004] 1. Due to the small size and low rigidity of the superstructure deck structure components, they are prone to large deformations during welding and construction.

[0005] 2. The increased workload of welding construction places higher demands on shipyard production and construction (including welding processes, precision control, deformation control, etc.).

[0006] 3. It is not conducive to controlling the weight of the superstructure and the height of the center of gravity, which affects the stability and comfort of passenger (roll-on) ships. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the above-mentioned defects in the existing technology and provide a ship superstructure deck structure.

[0008] The present invention solves the above-mentioned technical problems through the following technical solution:

[0009] A superstructure deck structure for a ship, installed on a passenger ship or a ro-ro passenger ship; it includes stiffened plate units; each stiffened plate unit includes a transverse plate-shaped portion and a reinforcing rib, with a joint portion and a groove-shaped portion respectively provided at both ends of the transverse plate-shaped portion; two reinforcing ribs are provided at the bottom of the transverse plate-shaped portion, one of which is connected to the middle of the transverse plate-shaped portion, and the other is located below the groove-shaped portion; the transverse plate-shaped portion, the reinforcing rib, the joint portion, and the groove-shaped portion are integrally formed; there are multiple stiffened plate units, which are connected in sequence to form the superstructure deck; in two adjacent stiffened plate units of the superstructure deck, the joint portion of one stiffened plate unit is inserted into the groove-shaped portion of the adjacent stiffened plate unit.

[0010] Furthermore, the reinforcing ribs are T-shaped.

[0011] Furthermore, the web of the reinforcing rib is perpendicular to the transverse plate-like portion.

[0012] Furthermore, the reinforcing ribs are parallel to the transverse plate-like portion.

[0013] Furthermore, the stiffened plate unit is made of aluminum alloy.

[0014] Furthermore, the spacing between the various reinforcing ribs in the superstructure deck is equal.

[0015] Furthermore, adjacent stiffened plate units are connected by welding.

[0016] Furthermore, the transverse plate-like portions of the sequentially connected stiffened plate units form a flat deck surface.

[0017] Furthermore, the connector portion has a lateral extension end; the groove portion has a groove that can be adapted to the lateral extension end.

[0018] Furthermore, the stiffened plate unit is an extruded assembly.

[0019] The beneficial effects of this utility model are as follows: By using a deck composed of stiffened plate units instead of a deck with conventional welded plate stiffeners, this utility model can reduce welding operations, reduce welding deformation, control the center of gravity of the superstructure, and improve the stability and comfort of passenger (roll-on) ships.

[0025] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0026] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a ship superstructure deck structure is provided on a passenger ship or a ro-ro passenger ship; it includes stiffened plate units 10.

[0027] The stiffened plate unit 10 includes a transverse plate-shaped portion 11 and a reinforcing rib 12. The transverse plate-shaped portion 11 has a joint portion 13 and a groove-shaped portion 14 at both ends.

[0028] The bottom of the transverse plate-shaped part 11 is provided with two reinforcing ribs 12, one of which is connected to the middle of the transverse plate-shaped part, and the other is located below the groove-shaped part.

[0029] The reinforcing rib 12 is T-shaped. The web of the reinforcing rib 12 is perpendicular to the transverse plate-like portion 11. The face plate of the reinforcing rib 12 is parallel to the transverse plate-like portion 11.

[0030] The transverse plate-shaped portion 11, the reinforcing rib 12, the joint portion 13, and the channel-shaped portion 14 are integrally formed. The stiffened plate unit 10 is an extruded assembly. The stiffened plate unit 10 is made of aluminum alloy.

[0031] There are multiple stiffened plate units 10, which are connected in sequence to form the superstructure deck 20. In two adjacent stiffened plate units of the superstructure deck, the joint of one stiffened plate unit is inserted into the groove of the adjacent stiffened plate unit.

[0032] The connector portion 13 has a lateral extension end; the groove portion 14 has a groove that can be adapted to the lateral extension end.

[0033] The spacing between the stiffeners 12 in the superstructure deck 20 is equal. Adjacent stiffened plate units 10 are connected by welding.

[0034] The transverse plate-like portions of the sequentially connected stiffened plate units form a flat deck surface.

[0035] In this design, the stiffened plate unit is a composite structure with built-in reinforcing ribs, eliminating the need for separate welding. The plate thickness (t), rib spacing (m), and rib dimensions can be determined based on actual requirements. The stiffened plate unit can be manufactured individually through extrusion molding. The superstructure deck structure of passenger (roll-on / roll-off) ships can be constructed by butt-welding multiple stiffened plate units together to form the overall support frame of the superstructure.

[0036] This invention uses a deck composed of stiffened plate units instead of a conventional welded plate stiffener structure, which can reduce welding operations, reduce welding deformation, control the center of gravity of the superstructure, and improve the stability and comfort of passenger (roll-on) ships.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
