Description
Technical Field
The utility model relates to the technical field of ships, in particular to a vertical groove type bulkhead structure.
Background
Bulk carriers are divided into several cargo holds for loading cargo respectively, and the vertical tank bulkheads are used for separating the cargo holds of the ship body and are usually formed by connecting wavy pressed flat steel plates in a welding or bending mode.
In the conventional vertical channel bulkhead, all channel panels are equal in size, and the plate thickness of a single channel is determined by the plate thickness requirement of the maximum area.
For the storm cabin of a bulk cargo ship, the storm cabin is stressed and pulled, the stressed surface bears larger buckling load, the thickness of the groove strip is determined by the size requirement of the stressed surface, and the conventional design has larger design allowance of the stressed surface, so the phenomenon of weight waste exists.
For solving the buckling problem of the vertical tank type bulkhead, two methods are realized, namely, the width of the panel of the tank strips is uniformly reduced, but the number of the tank strips is increased, so that the weight of the ship is increased; the second is to reduce the length of the channel strips, but this increases the volume of the bottom or top piers, which in turn leads to a reduction in the hold capacity of the hold and an increase in the weight of the ship.

FIG. 2 is a schematic sectional view taken along line A-A in FIG. 1.
Detailed Description
The present invention will be more clearly and completely described in the following description of preferred embodiments, taken in conjunction with the accompanying drawings.
As shown in fig. 1 and 2, a vertical channel bulkhead structure includes a web 10 and panels provided on both sides of the web; the web and the panel form vertically distributed groove strips. The number of the groove strips is multiple.
The panels include compression panels 20 and tension panels 30.
The face plate on one side of the web is a compression face plate 20 which mainly receives external compression force, and the face plate on the other side of the web is a tension face plate 30 which mainly receives external tension force.
The width of the tension panel 30 is greater than that of the compression panel 20. The width of the compression panel 20 is greater than half of the width of the tension panel 30.
The angle between the web 10 and the tension panel 30 is not less than 55 °; the compression panels 20 are parallel to the tension panels 30. The angle between the web 10 and the compression face plate is the same as the angle between the web and the tension face plate.
The thickness of the compression panel 20 is the same as that of the tension panel 30.
The compression and tension panels 20 and 30 are provided in plurality, all of which are located on the same plane, and all of which are located on the same plane.
The connecting lines of the web 10 and the compression panel 20 are vertically distributed; the connecting lines of the web 10 and the tension panel 30 are vertically distributed. The connection line of the web 10 and the compression panel 20 is parallel to the connection line of the web 10 and the tension panel 30.
The width of the notch formed by the compression face plate 20 and the two webs connected to both ends of the compression face plate is smaller than the width of the notch formed by the tension face plate 30 and the two webs connected to both ends of the tension face plate.
The two webs connected to the two ends of the compression panel are symmetrical about the perpendicular bisector of the compression panel. Two webs connected to both ends of the tension panel are symmetrical about a perpendicular bisector of the tension panel.
In this embodiment, the web, the compression face plate, and the tension face plate are integrally formed.
In the case of bulk freighters, the vertical channel walls are subjected to a certain pressure when they are loaded with bulk cargo, but are small relative to the pressure of the ballast water that the storm ballast tanks may be subjected to, the latter often being dominant in the structural design, i.e. the vertical channel walls adjacent to the storm tanks, the panels on that side of the storm tanks are subjected to pressure and the other side panels are correspondingly subjected to tension.
The vertical groove-shaped bulkhead is provided with the panels with different widths between the bottom plate of the top pier and the top plate of the bottom pier. On the side that is subjected to the pressure, a panel of narrower dimensions is used, while on the other side, which is in tension, a panel of wider dimensions is used.
The thickness of the tank bulkhead is proportional to the width of the panel, and the thickness of the panel is thicker as the width of the panel is larger. In the present invention, the pressed panel has a small width, and the panel thickness determined according to the pressed panel is small. The panel thickness of the tank bulkhead is determined only by the pressed panel with small width, and the panel thickness is not determined by the pulled panel with large width, so the plate thickness of the vertical tank bulkhead is greatly and effectively reduced, and the weight of the tank bulkhead is further reduced.
The utility model improves the prior vertical groove type bulkhead structure, adopts the groove strip form of the panels with different widths, does not increase the construction difficulty compared with the prior proposal, and simultaneously can obviously reduce the weight of the groove type bulkhead structure and reduce the manufacturing cost on the premise of ensuring the strength of the vertical groove type bulkhead.
While specific embodiments of the utility model have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and that the scope of the utility model is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the utility model, and these changes and modifications are within the scope of the utility model.
