Description

Technical Field

[0001] The invention relates to the field of container ship structure design, and is a bulwark support bracket design scheme which takes into account the bulwark support and box column functions and has the advantage of improving the loading capacity of the container ship. Background Art

[0002] In recent years, as the technology of large-scale and ultra-large container ships continues to mature, the carrying capacity of container ships has gradually increased. In 2021, the Hercules series ship type 23000TEU designed by the China Ship and Ocean Engineering Design Institute was successfully launched. The maximum container capacity of container ships has increased nearly five times in the past 20 years. How to make better use of deck space and load more containers has been the focus of container ship design optimization in recent years.

[0003] The bow of a container ship is often designed with bulwarks to block the waves, but the presence of bulwarks and their supporting brackets makes the container layout area at the bow of the ship, which is already narrow due to the shrinkage of the ship's lines, even more compact. The current container ship design often chooses to arrange at least two rows of containers on both sides of the stacking area near the bow to ensure the normal layout of the bulwarks.

[0004] like Figure 1 As shown, the bow container stacking area (right) has two fewer rows of containers on each side of the deck compared to the container stacking area near the bow (left).

[0005] Therefore, the above technology has the problem that the space of the bow deck of the ship is not fully utilized and the number of containers is small. The existing bulwarks and their supporting brackets and the ship lashing system are independently designed by the structural professionals and the outfitting professionals respectively, which has the problem that the space of the bow deck of the ship is not fully utilized and the number of containers is small. Summary of the invention

[0006] The purpose of the present invention is to provide a new type of integrated structural design of bulwark support bracket and box column, which considers from the overall level that a single bracket structure not only meets the function of supporting the bulwark, but also has the function of box column. By comprehensively considering the shape and reinforcement form of the bulwark support bracket, it can meet the functional requirements of the box column and combine the corresponding under-deck reinforcement structure. This structural design, firstly, saves the bow layout space by simplifying the structure, so that the number of boxes is increased; secondly, the number of components is reduced by structural fusion, which is beneficial to shipyard construction.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the present invention provides a bulwark supporting bracket structure with box column function, the bracket structure is located at the bow of the ship, on the inner side of the bow bulwark, and is arranged symmetrically on the left and right. The main body includes a bulwark supporting side one and a box column side. The bulwark supporting side one and the box column side are connected and fixed by a supporting beam and a connecting bracket to meet the functional requirements of both bulwark support and box column lashing.

[0008] Preferably, the container support platform is mounted between the bulwark support brackets.

[0009] Preferably, the container support platform and the lashing bridge column support platform are supported on the upper deck through the bulwark support bracket and the platform support plate.

[0010] Preferably, the container support platform and the lashing bridge column support platform are reinforced by platform support bracket 1 and platform support bracket 2 and the bulwark support bracket.

[0011] Preferably, the subsequent box feet are installed at the areas where the platform support bracket 1 and the platform support bracket 2 are reinforced.

[0012] Preferably, the bulwark support bracket panel one can be enlarged to provide support for the platform.

[0013] Preferably, the shapes of the platform support bracket plate 1 and the platform support bracket plate 2 can be deformed according to the specific installation position.

[0014] Preferably, the bulwark supporting side one and the bulwark supporting side two can be deformed, and the bulwark supporting bracket panel two and the bulwark supporting bracket panel three can be adjusted in shape.

[0015] Preferably, the specific shape, plate thickness and anti-tilt bracket position of the bulwark support bracket panel 2 and the bulwark support bracket panel 3 can be adjusted by adding stress fatigue analysis at the corner.

[0016] Preferably, the web height of the upper part of the bulwark supporting bracket in the adjacent area is compressed, and the height of the bulwark supporting side 2 at the lower part of the bulwark supporting bracket and the thickness of the bulwark supporting bracket panel 3 are increased so that the needs of bulwark support can still be met.

[0017] The present invention proposes a novel bulwark support bracket and box column integrated structure design scheme, which can not only realize the bulwark support function, but also has the box column lashing function, and the beneficial effects are mainly as follows:

[0018] 1. By installing this new bracket, the bow deck space can be used more effectively. The saved space can be used to add one row of stacking containers on the left and right of the original stacking state of the bow deck of the ship, thereby increasing the number of containers on the ship. Moreover, the added stacking containers are high-value-added spaces that can be used to load dangerous goods.

[0019] 2. Through structural integrated design, the number of parts is reduced, which is beneficial to shipyard construction.

[0020] 3. The integrated design reduces the complexity of the reinforced structure, which is beneficial to ship weight reduction.

[0021] Therefore, the above-mentioned novel bulwark support bracket structure design scheme has an improving effect on the comprehensive performance of container ships. BRIEF DESCRIPTION OF THE DRAWINGS
