Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hull shape.

[0002]

[Prior Art]

 Generally, the conventional hull shape is as shown in FIG. 6 (a), in which the bow 1a and the stern 1b of the hull 1 are located above the bottom 1c of the bows 1a and 1b for the purpose of reducing the wave-making resistance. The outer plate 4 extending to the deck 1d has a curved shape with a continuous smooth curve, and the bow 1a and the stern 1b have a rounded bow end 3 as shown in Fig. 6 (b). The stern end 3a is configured to be connected to the outer plate 4 which is bent into a smooth continuous curved surface. The outer plate 4 is integrated by providing a welding joint according to the size or thickness of the steel plate.

[0003]

[Problems to be solved by the device]

 However, in the case of the conventional hull shape described above, the part connecting from the curved portion near the bow end 2 and near the stern end 2a of the hull to the roundness R of the bow end 3 and the stern end 3a has a complicated curved surface over a wide range. However, this part is the most bent part of the steel plate, it is a difficult place to work, and it is a place that requires skill, so the bending range of the steel plate is large, and the curvature is not constant and it is suitable for three-dimensional processing. It requires skill, the bending process takes time accordingly, and the bending accuracy is also required, which requires more time for processing. There are problems such as difficulty in bending, and lack of small rounded curved surfaces at the bow and stern edges due to plate thickness.

Therefore, the present invention minimizes bending work of thick steel plates in the range from near the bow end or near the stern end to the end, so that even a skilled worker can easily improve the working accuracy while improving the working accuracy. It provides a hull shape that can be processed.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a knuckle on the outer plate of one or both of the vicinity of the bow end and the stern end of the hull, and from the knuckle to the bow end and / or the stern end. The outer plate that reaches is linear in a plan view.

A round bar may be used at the bow end and / or the stern end.

Further, one or both ends of the bow side and the stern side of the hull may be cut, and a block made of a easily workable material may be attached to the cut surface.

Further, the block may be composed of an outer plate made of a thin steel plate and a filler that fills a space between the outer plate and the cut surface on the hull side.

[0009]

[Action]

 If a knuckle is provided on one or both of the outer plates near the bow end and the stern end of the hull, and if the outer plate is straight from the knuckle to the bow end and / or the stern end, the bending range of the steel plate will be Since the amount is reduced, the processing becomes easier, the processing time can be shortened, and the working accuracy can be easily improved. In addition, if a block made separately of a material that is easy to process is attached as an additive to the end of either or both of the bow side and the stern side of the hull to form the hull, bending work of thick steel plate will be performed as described above. This reduces the amount of time spent, and the time spent on machining work can be greatly reduced, improving work efficiency.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

1 to 5 show an embodiment of the present invention. FIG. 1 shows a knuckle 5 provided on an outer plate 4 near a bow end 2 and a stern end 2a of a hull 1, and each knuckle 5 Therefore, the outer plate 4a which is processed linearly is arranged from the bow end 3 and the stern end 3a, which intersect with the center line CL of the hull, to form a sharp bow-shaped bow and a stern-shaped bow. The knuckle 5 has an angle θ of 15 degrees or less with respect to the virtual extension line of the outer plate 4 in FIG. If a knuckle 5 is provided on the outer plate 4 near the bow end 2 and near the stern end 2a, and the straight outer plate 4a extends to the bow end 3 and the stern end 3a, the bending portions of the bow 1a and the stern 1b are Since there are no curved shapes in many places that are difficult to process, and the sharpened bow 1a and stern 1b have a two-dimensional surface structure, the bending range and amount of bending of the hull 1 can be reduced. Moreover, the machining becomes easier, the machining time can be shortened, and the machining accuracy can be improved. Further, since the knuckle 5 is set at 15 degrees or less with respect to the virtual extension line of the outer plate 4 extending in a curved shape, the hull resistance can be reduced. The knuckle 5 and the bow end 3 or the stern end 3a are usually constructed by welding joints.

FIG. 2 shows another embodiment of the present invention. In a configuration similar to that of FIG. 1, a metal round bar 6 having a small radius is used at the bow end 3 and the stern end 3a to make the bow and tail ends. 3,3a is processed.

In this embodiment, the round bar 6 and the outer plate 4a are joined by welding.

Next, FIG. 3 shows still another embodiment of the present invention, in which the knuckle 5 is provided in the vicinity of the bow end 2 and the vicinity of the stern end 2a of the hull 1 in each of the embodiments described above. In place of the hull shape that facilitates the processing of the a and the stern portion 1b, each of the bow 1a and the stern portion 1b of the hull 1 is cut into a shape such that the cut surface 7 is made of a rubber that is easily workable. The block 8 is made by separately processing with materials such as cement, wood, FRP, plastic, clay, cork, and thin steel plate, and is attached as an additional structure.

As described above, when the curved portions of the bow 1a and the stern 1b are separately processed by using a material having a simple processability, the block 8 is attached to form the stern end. Not only does this improve the machining accuracy of the parts that are often bent, but it also significantly reduces the amount of time that was conventionally spent in 3D machining.

FIG. 4 shows a modified example of FIG. 3, in which the block 8 is an outer plate 4 b having a curved shape made of a thin steel plate which is easy to process, and the block 8 is provided between the outer plate 4 b and the cut surface 7. The space 9 thus formed is reinforced by filling it with a filling material such as cement or plastic, and the block 8a is attached to the bow 1a and the stern 1b as an additive.

Further, FIG. 5 shows still another modified example, in which the outer plate 4a using the thin steel plate forming the block 8a is processed into a nearly straight line so that the bow end 3 and the stern end 3a are formed. The shape is changed from an arc shape to a sharp shape.

It should be noted that the present invention is not limited to the above-described embodiment, and for example, the case where one knuckle 5 is provided on each of the bow portion 1a and the stern portion 1b is shown. However, in each embodiment, the knuckle 5 is provided on both the bow 1a and the stern 1b, or the block 8 or 8a is attached, but only one of the bow 1a and the stern 1b is shown. However, it goes without saying that various changes can be made without departing from the scope of the present invention.
