Description

Technical Field

[0001] The invention belongs to the technical field of ship construction, and in particular relates to a non-watertight patching device for a through-hole of a T-shaped material of a ship. Background Art

[0002] When the continuous T-profile of a ship passes through the intersecting non-watertight main structure, in order to facilitate installation, most of the through holes are made into gate-shaped holes. These holes will not only cause the effective area loss of the main structure, but also reduce the connection area between the T-profile and the main structure, making it impossible to effectively transfer the force of the T-profile to the main structure. Therefore, in most cases, it needs to be sealed with a patch plate. There are two patches, one side is welded to the web of the T-profile at an angle, and the other side is 30 to 50 mm wider than the through hole and overlapped and welded to the main structure.

[0003] Firstly, the existing patch plate adopts the overlapping method, and the patch plate and the main structural plate with holes are not in the same plane. When subjected to stress, additional bending moment and shear force will be generated, which is prone to fatigue and insufficient strength problems.

[0004] Secondly, according to the installation process, the patch plate can only be installed after the main structure and the T-profile and the plate where the T-profile are located are assembled. Therefore, it is necessary to use the mounting or later bulk installation and welding method. When the mounting solution is adopted, the patch plate is generally welded to the structure near the through hole in the form of spot welding, which will cause the following problems: first, it will damage the paint, second, it will increase the time cost of welding and removal, and third, it will be lost during transportation due to weak spot welding; if the bulk method is adopted, manual handling is required, the labor intensity is high, and it is time-consuming and laborious to find matching parts. Moreover, the construction stage of the above two methods is generally in the middle and late stages, with poor working environment and high construction difficulty, which does not conform to the concept of green shipbuilding. Summary of the invention

[0005] The present invention provides a non-watertight patching device for a through hole of a T-shaped material of a ship, comprising:

[0006] A main structural plate, wherein the main structural plate is provided with a door-shaped opening;

[0039] like Figures 1 to 3 As shown, the present invention provides a non-watertight patching device for a through hole of a T-shaped material of a ship, which is explained below with a specific embodiment:

[0040] The main structure plate 1 is welded to the base plate 4, the bottom of the T-profile web 3 is welded to the base plate 4, the main structure plate 1 is provided with a door-shaped opening 2, the T-profile web 3 passes through the door-shaped opening 2, the left supplementary plate 6 and the right supplementary plate 5 are located in the door-shaped opening 2, the left supplementary plate 6 is located on the left side of the T-profile web 3, and the right supplementary plate 5 is located on the right side of the T-profile web 3.
