Structure at the opening of a ship structure

Abstract

The present invention relates to a structure at an opening of a ship structure, comprising: a pair of stiffeners that are parallel to each other in the vertical direction and continuously penetrate through a ship platform, and a first platform member that horizontally covers the area between the pair of stiffeners; a second platform member that has a first notch conforming to the shape of the first platform member and a second notch conforming to the shape of the opening of the ship structure opening. In the present invention, the stiffener part and the opening part of the platform are designed as two independent components. The stiffeners do not need to be disconnected, nor are there any strengthening brackets required; since a through hole is formed in the first platform member itself, there is no need to separately provide a stiffener through hole on the platform either; while ensuring the continuity of the stiffeners, the support requirements of the opening and the platform for the stiffeners are also met.

Description

Technical Field

[0001] The present invention relates to a structure at an opening of a ship structure, belonging to the technical field of ship design. Background Art

[0002] In ship structure design, there are openings designed for passages and through holes designed for the penetration of stiffeners on the platform at the same time.

[0003] Sometimes, the openings and the through holes of the stiffeners are very close. The existing technology is to disconnect the stiffeners, cancel the through holes of the stiffeners, and add gussets at both ends of the stiffeners to improve the welding requirements at the ends of the stiffeners, so as to meet the opening requirements and the strength requirements of the stiffeners at the same time. The above-mentioned existing technology practices have technical problems such as high cost, low efficiency, high energy consumption, and inconvenient use. Summary of the Invention

[0004] The purpose of the present invention is to provide a ship structure opening structure, which designs the stiffener part and the opening part of the platform as two independent components. The stiffeners do not need to be disconnected, and while ensuring the continuity of the stiffeners, it also meets the support requirements of the opening and the platform for the stiffeners.

[0005] The present invention adopts the following technical solutions:

[0006] A structure at an opening of a ship structure, comprising: a pair of stiffeners 2 that are parallel to each other in the vertical direction and continuously penetrate through the ship platform, and a first platform component 4 that horizontally covers the area between the pair of stiffeners 2; a second platform component 5 that has a first notch 501 that is shaped like the first platform component 4 and a second notch 502 that is shaped like the opening of the ship structure opening.

[0007] Preferably, after the first notch 501 and the second notch 502 are connected, they form a larger notch.

[0008] Furthermore, the first notch 501 and the second notch 502 have a common side.

[0009] Preferably, the first notch 501 is rectangular, and the second notch 502 is rectangular with rounded corners.

[0010] Preferably, the stiffeners 2 are made of bulb flats.

[0011] Preferably, the first platform component 4 and the second platform component 5 are welded and fixed.

[0012] Furthermore, the second platform component 5 and the main body part of the platform are welded and fixed.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1) Design the girder part and the opening part of the platform as two independent components. The girder does not need to be disconnected, nor is it necessary to set reinforcing brackets.

[0015] 2) Since a through-hole is formed at the first platform component itself, there is no need to separately set a through-hole for the girder on the platform.

[0016] 3) While ensuring the continuity of the girder, it also meets the support requirements of the opening and the platform for the girder. Description of the Drawings

[0023] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0024] Embodiment 1 (Comparative Embodiment):

[0025] See Figure 1 , Figure 1 which shows a partial view in a planar perspective of the ship platform. In the figure, the position of the girder 2 is close to the opening on the platform, and a through-hole 1 for the girder needs to be opened around the girder 2. When the distance between the through-hole 1 for the girder and the opening on the platform is too small, it will affect the local strength and may not meet the strength requirements.

[0026] Embodiment 2 (Comparative Embodiment):

[0027] See Figure 2 , to solve the problems existing in Embodiment 1, in this comparative embodiment, the girder at the platform is disconnected, the design of the through-hole is cancelled, and brackets are added to both ends of the girder (such as Figure 3As shown, the welding requirements at the end of the structural member are increased to simultaneously meet the opening requirements and the strength requirements of the structural member. The method in this embodiment has technical problems such as high cost, low efficiency, high energy consumption, and inconvenient use.

[0028] Embodiment 3:

[0029] To solve the problems existing in Embodiment 2, refer to Figures 4-5 ,:

[0030] A structure at the opening of a ship structure, comprising: a pair of structural members 2 that are parallel to each other in the vertical direction and continuously penetrate through the ship platform, and a first platform member 4 that horizontally covers the area between the pair of structural members 2; a second platform member 5 that simultaneously has a first notch 501 that conforms to the shape of the first platform member 4 and a second notch 502 that conforms to the shape of the opening of the ship structure opening.

[0031] Combined with Figures 4-5 , a larger notch is formed after the first notch 501 and the second notch 502 are connected.

[0032] Continuing to combine Figures 4-5 , the first notch 501 and the second notch 502 have a common side.

[0033] In this embodiment, refer to Figure 5 , the first notch 501 is rectangular, and the second notch 502 is rectangular with rounded corners.

[0034] Refer to Figure 4 , the structural member 2 is made of bulb flat steel, Figure 4 What is shown is the cross-section of the bulb flat steel.

[0035] Refer to Figure 4 , the first platform member 4 and the second platform member 5 are welded and fixed.

[0036] Continuing to refer to Figure 4 , the second platform member 5 and the platform main body part are welded and fixed.

[0037] In this embodiment, the platform is segmented to ensure the opening and the strength of the structural member. Specifically:

[0038] The structural member part and the opening part of the platform are designed as two independent components. The structural member does not need to be disconnected, nor is it necessary to set up a reinforcing bracket; since a through hole is formed in the first platform member itself, there is no need to separately set up a through hole for the structural member on the platform; while ensuring the continuity of the structural member, the support requirements of the opening and the platform for the structural member are also met.

[0039] The above Example 3 is a preferred embodiment of the present invention. Those of ordinary skill in the art can also make various transformations or improvements on this basis. Without departing from the general concept of the present invention, these transformations or improvements should fall within the scope of protection required by the present invention.
