Description

A plug-welded structure in a narrow compartment area of ​​a ship section Technical Field

[0001] This utility model belongs to the field of shipbuilding technology, and specifically relates to a plug welding structure in a narrow compartment area of ​​a ship section. Background Technology

[0002] Car carrier hulls often feature unique structural elements such as ramps, rudders, and stern doors, with confined spaces within narrow, dead-end compartments. To meet structural strength requirements, facilitate on-site construction, and maintain aesthetics, plug welds are frequently used in these areas. Because the plug weld holes are large in thick plates, epoxy is filled between the welded edges. However, during actual use, vibrations and external factors inevitably cause the epoxy to peel off, necessitating repair. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a plug-welded structure for narrow compartment areas in ship sections. Round steel is embedded in the plug-welded holes and then electric welded. After epoxy is filled in, the stability of the epoxy itself can be improved by relying on the round steel.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A plug-welded structure for a narrow compartment area in a ship section includes a plug-welded steel plate with multiple plug-welded holes. At least one reinforcing rib and epoxy filler are provided in each plug-welded hole. The two ends of the reinforcing rib are fixedly connected to the inner sidewall of the plug-welded hole, and the reinforcing rib is located inside the epoxy filler.

[0006] Furthermore, the length direction of the reinforcing rib is arranged along the length direction of the plug weld hole.

[0007] Furthermore, the number of reinforcing ribs is one, and the central axis of the reinforcing rib coincides with the central axis of the plug weld hole.

[0008] Furthermore, the two ends of the reinforcing rib are welded to the inner wall of the plug weld hole.

[0009] Furthermore, there are multiple reinforcing ribs, which are staggered within the plug weld holes.

[0010] Furthermore, the reinforcing rib is made of round steel with a diameter of 5mm.

[0011] The plug-welded structure in the narrow compartment area of ​​the ship section of this utility model can improve the stability of the epoxy itself by relying on the round steel after epoxy is filled, reduce the damage to the epoxy caused by vibration generated by the ship itself and external interference, extend the service life of the epoxy, and extend the epoxy repair cycle.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] As shown in Figures 1-3, a plug-welded structure for a narrow compartment area in a ship section includes a plug-welded steel plate 1. Multiple plug-welded holes 11 are formed on the steel plate 1. At least one reinforcing rib 2 and epoxy filler 3 are provided within each plug-welded hole 11. The two ends of the reinforcing rib 2 are fixedly connected to the inner wall of the plug-welded hole 11, and the reinforcing rib 2 is located inside the epoxy filler 3. Specifically, the two ends of the reinforcing rib 2 are welded to the inner wall of the plug-welded hole 11.

[0018] In some embodiments, the number of reinforcing ribs 2 is one, the length direction of the reinforcing rib 2 is arranged along the length direction of the plug weld hole 11, and the central axis of the reinforcing rib 2 coincides with the central axis of the plug weld hole 11.

[0019] In other embodiments, there are multiple reinforcing ribs 2, which are staggered within the plug weld holes 11.

[0020] Furthermore, the reinforcing rib 2 is a round steel bar with a diameter of 5mm.

[0021] Those skilled in the art should understand that the above description is merely a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
