[0019] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1-2As shown together, this embodiment is about the reinforced ship side structure, which is essentially the two side walls in the hull connecting the bottom and the deck. Different from the traditional transverse frame side and longitudinal frame side, the side structure is re-optimized and designed to increase the cabin capacity utilization while maintaining the hull's excellent resistance to lateral and longitudinal forces.

[0021] The present embodiment comprises a side outer plate 1, a longitudinal member arranged along the length direction is welded to the inner side of the side outer plate 1, the longitudinal member comprises a side longitudinal bone 3 and a side longitudinal girder 4, a bracket 9 is connected to the connecting position of the end side of the side longitudinal girder 4, a transverse frame is also welded to the inner side of the side outer plate 1, the transverse frame comprises a main rib 5, a side rib 6 and a side rib 10 arranged at intervals in the longitudinal member, and the side rib 6 is connected to the side outer plate 1 through a T-shaped composite material 7 and an L-shaped composite material 8.

[0022] Preferably, the side outer plate 1 is based on the external tire frame and is implemented by segmented welding, that is, Figure 1 The structural schematic diagram shown is a single-section structure during assembly and welding.

[0023] Furthermore, the maximum length of the side longitudinal bones 3 of each section of the side outer plate 1 is slightly longer than the maximum length of the side longitudinal girders 4. The number of the side longitudinal bones 3 and the side longitudinal girders 4 are both multiple and the two are arranged alternately from the bottom of the ship to the deck. That is to say, from the bottom of the ship to the deck, the odd-numbered longitudinal members are the side longitudinal bones 3, and the even-numbered longitudinal members are the side longitudinal girders 4.

[0024] Furthermore, the size of the side longitudinal bone 3 below and above the waterline is the same, one end of the side longitudinal bone 3 extending in length is flush with the discontinuity of each section of the side outer plate 1, and the other end of the side longitudinal bone 3 extending in length is welded to the side end surface of the main rib 5. At the same time, based on the technical feature that the maximum length of the side longitudinal bone 3 is slightly longer than the maximum length of the side longitudinal girder 4, it can be understood that the side of the side longitudinal bone 3 flush with the discontinuity of each section of the side outer plate 1 passes through the gap between the side rib 6 and the side outer plate 1.

[0025] Preferably, the web width of the side longitudinal girder 4 is greater than the width of the main rib 5. This design increases the rigidity of the side and transfers part of the load on the side outward. At the same time, it can also reduce the cross-sectional size of the main rib 5 and increase the cabin capacity utilization rate. One end of the side longitudinal girder 4 extending in length is welded to the main end face of the main rib 5, and the other end of the side longitudinal girder 4 extending in length is welded to the main end face of the side rib 6. That is to say, the two ends of the side longitudinal girder 4 in the length direction are welded between the main rib 5 and the side rib 6, and since the side rib 6 is not directly welded to the main body and the side outer plate 1, it can be understood that the web width of the side longitudinal girder 4 is also greater than the web width of the side longitudinal rib 3.

[0026] Preferably, the bracket 9 is welded to the lower surfaces of both ends of the side longitudinal girder 4 at the positions where they are connected to the main ribs 5 and the side ribs 6 on their respective sides. The bracket 9 is used to increase the structural strength of the connecting position, that is, the connecting node, thereby increasing the integrity of the longitudinal members and the transverse members.

[0027] Compared with the traditional structure, the present embodiment innovatively adds a side rib 10 between the side longitudinal bone 3 and the side longitudinal girder 4, the upper end of the side rib 10 is welded to the middle position of the side longitudinal bone 3 on its upper side, and the lower end of the side rib 10 is welded to the middle position of the side longitudinal girder 4 on its lower side, and the side rib 10 is perpendicular to the side longitudinal bone 3 and the side longitudinal girder 4 respectively. Through the arrangement of the side rib 10, the longitudinal impact resistance of the hull is enhanced, the continuity of the longitudinal components is ensured, and the stress concentration phenomenon is reduced. In particular, when the hull is longitudinally bent, the side is subjected to tension, pressure and shear force, and the lateral force transmitted locally is actively borne by the side rib 10, thereby improving the strength and stability of the side.

[0028] Furthermore, the side rib 10 includes a reinforcing base 11 welded to the side longitudinal girder 4, and also includes a first reinforcing material 12 and a second reinforcing material 13 hinged to each other. When the side rib 10 is subjected to force, a slight deformation actively occurs through the hinged form between the first reinforcing material 12 and the second reinforcing material 13, thereby relieving the shear stress of the side rib 10.

[0029] In addition, there are two L-shaped composite materials 8, which are respectively located at the upper and lower ends of the side ribs 6. There are several T-shaped composite materials 7, which are all located between the upper and lower L-shaped composite materials 8 and correspond to the positions where the side longitudinal girder 4 and the side ribs 6 are welded.

[0030] Reinforcement ribs 2 are formed at positions of the side outer plate 1 corresponding to the side longitudinal girder 4 .

[0031] In this way, the reinforced ship side structure disclosed by the utility model breaks the traditional stereotyped distinction between transverse frame side and longitudinal frame side, and specifically divides the side structure into transverse members and longitudinal members. The transverse members are equipped with main ribs 5 and side ribs 6 that cooperate with each other to increase the transverse strength of the side, and creatively arrange side ribs 10 between the longitudinal members to ensure the continuity of the longitudinal members, reduce stress concentration, actively bear the locally transmitted lateral forces, improve the strength and stability of the side, and limit the web width of the side longitudinal girders 4 and the side longitudinals 3 to ensure strength while increasing the cabin capacity utilization.

[0032] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
