[0028] Among them, the corrugated bulkhead is connected to the deck surface and the deck girders.

[0029] At the position where the corrugated bulkhead panel intersects the deck girder, a first bracket and a patch plate are provided on the deck surface.

[0030] A second bracket is connected between the deck longitudinals on the deck surface at the connection of the corrugated bulkhead web and the deck surface.

[0031] The deck longitudinals are arranged at the position where the plane of the other panel of the corrugated bulkhead intersects the deck girder.

[0032] An opening structure is provided on the web at the intersection of the plane of the other panel of the corrugated bulkhead and the deck girder, and the opening structure is arranged between two deck longitudinals.

[0033] As Figure 3 shown, in some embodiments of the present invention, the toe end of the first bracket is prevented from terminating at the fold angle of the corrugated bulkhead panel and the web of the corrugated bulkhead, and can terminate within the range of the corrugated bulkhead panel, or can cross the panel range.

[0034] As a further optimization of this embodiment, the distance a between the toe end of the first bracket and the fold angle of the corrugated bulkhead panel and the web is greater than or equal to 50 mm. The toe end of the first bracket is designed as a soft toe structure, and the angle Ф1 of the soft toe is not greater than 20°.

In this embodiment, the opening height of the drain hole is less than or equal to 1 / 4 of the height of the bracket. The deck longitudinals within 200 mm near the soft toe of the toe end of the bracket are prevented from being opened. Within the range of 100 mm of the corrugated bulkhead fold angle, the deck stiffeners corresponding to the corrugated bulkhead panel are prevented from being opened.

[0038] As a further optimization of this embodiment, the angle Ф2 between the opening structure and the deck surface is 45° - 90°, and the opening structure can adopt the form of anti-fatigue soft toes.

[0039] Next, through an example, a ship corrugated bulkhead deck structure provided in the technical solution of the present invention will be further elaborated. As Figures 1 to 5 shown, a ship corrugated bulkhead deck structure includes a corrugated bulkhead, a deck surface, deck beams, and deck longitudinal girders.

[0040] Among them, the corrugated bulkhead is connected to the deck surface and the deck beams.

[0041] At the position where the corrugated bulkhead panel intersects with the deck beam, a first bracket and a patch plate are provided on the deck surface. The setting of the first bracket provides a stress transition effect for the connection between the corrugated bulkhead and the deck. In addition, the setting of the first bracket provides stability for the deck longitudinal girder and increases the connection area.

[0042] The second bracket is connected between the deck longitudinal girders on the deck surface at the connection of the corrugated bulkhead web and the deck surface.

[0043] The deck longitudinal girders are arranged at the position where the plane of the other panel of the corrugated bulkhead intersects with the deck beam.

[0044] As Figure 3 shown, the toe end of the first bracket is avoided from terminating at the fold angle between the corrugated bulkhead panel and the web of the corrugated bulkhead, and it can terminate within the range of the corrugated bulkhead panel or cross the panel range. The distance a between the toe end of the first bracket and the fold angle between the corrugated bulkhead panel and the web is 100 mm, and the toe end of the first bracket is designed as a soft toe structure, and the angle Ф1 of the soft toe is 20°.

[0045] As Figure 4 shown, drain holes are provided on the bracket to ensure smooth drainage and avoid water accumulation on the deck. The opening height of the drain holes is 1 / 4 of the height of the bracket. The deck longitudinal girders with a soft toe of 200 mm at the toe end of the bracket are avoided from being opened, and the deck stiffeners corresponding to the 100 mm range of the corrugated bulkhead fold and the corrugated bulkhead panel are avoided from being opened. Large weld-through holes are not allowed at the corner points where the bracket is connected to the deck longitudinal girder and the deck. See Figure 4At the asterisk. As Figure 5 shown, the distance d between the side of the opening structure and the first deck longitudinal girder is 10 mm, and the distance h between the top side of the opening structure and the first deck longitudinal girder is 10 mm; the distances between the side and the top side of the opening structure and the second deck longitudinal girder are the same as those of the first deck longitudinal girder. The end corners of the opening structure need to be rounded, and the radius r of the arc is 50 mm. The angle Ф2 between the opening structure and the deck surface is 60°, and the opening structure adopts an anti-fatigue soft toe form.

[0046] In the technical solution of the present invention, in addition to providing a ship corrugated bulkhead deck structure, a ship including the above-mentioned corrugated bulkhead deck structure is further provided.

[0047] It should be noted that all the terms indicating directionality and positional indication in the present invention, such as: "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "inner", "outer", "top", "bottom", "tail end", "head end", "center", etc., are only used to explain the relative positional relationship and connection situation between components in a specific state, and are only for the convenience of describing the present invention, rather than requiring the present invention to be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present invention. In addition, the descriptions involving "first", "second", etc. in the present invention are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or the solution where A and B are satisfied simultaneously.

[0048] In the present invention, unless otherwise clearly defined and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0049] The above are the preferred embodiments of the present invention.
