Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a small-sized ship structure such as a boat.

[Conventional technology]

Generally, when building a ship's hull, the outer shape of the ship is constructed by combining supporting aggregates and vertical aggregates, and then the bottom and side shell plates are attached along both aggregates.

[Problem that the invention seeks to solve]

However, in this method, a great deal of labor and time is required for processing and joining the aggregates, processing and pasting of the outer panels, etc., which is not at all preferable in terms of extended delivery times, high costs, and energy savings. .

[Means for solving problems]

This invention was made in view of the above circumstances,
A joint groove is provided along one joint side of the joint sides of a plurality of hollow shapes that integrally have connecting pieces that connect these face plates between a pair of facing face plates, and this joint groove is provided on the other side. It is characterized by having a joining protrusion that can abut or fit into the groove, and a plurality of reinforcing ribs that also serve as fins protruding from the outer surface of the outer surface plate of the hollow member that makes up the bottom of the ship. By constructing the bottom and sides using multiple hollow extruded sections molded into the same shape, it is possible to reduce labor and time during assembly work, as well as reduce costs and improve energy savings. In addition, by the presence of reinforcing ribs that also serve as fins and protruding from the outer surface of the bottom of the ship, the hollow shape that makes up the bottom of the ship can be reinforced, and in some cases, the inside of the hollow shape can be used as an oil tank or oil piping. The present invention aims to provide a hull structure that is characterized by enhanced cooling effect during use.

Embodiment Furthermore, in general, it is necessary to make the bow 7 and the stern 8 have variations, or to curve the bottom 1, so in this invention, when making the bow 7 and the stern 8 vary in width, For example, in contrast to the normal connection of the bottom constituent members 5 shown in FIG. 6, as shown in FIG.
After cutting the g side to a predetermined size and fitting the joint protrusion 5h of the adjacent member 5 into the cut hollow chamber 5d or abutting the side ends of the member 5, welding 6 is performed.
By doing this, the width of the bottom of the ship can be varied. In addition, in order to give the bottom 1 a curve, as shown in FIG. By shortening the length (Δl in the figure), adjacent members 5 are connected in an inclined manner at a slight angle Δθ, and by similarly connected in an inclined manner at each joint, the entire ship bottom can be formed into a curved shape. This is possible.

FIG. 9 shows an oil cooling section provided when the hollow chamber 5d of the member 5 is used as an oil tank or oil piping.The central chamber can be fully utilized as it is as an oil cooling section, but in this case, The reinforcing ribs 5j, .

On the other hand, as shown in FIGS. 3 and 10, the side 2 is formed by joining together a plurality of side members 5' formed of hollow shapes similar to the bottom member 5. The side 2 is connected to the bottom 1 via a corner member 9 forming a corner part 3, and a side handrail is provided at the top of the side 2. 10 is attached. In this case, the bow 7
Although it is necessary to vary the height of the side 2 from the stern to the stern 8, this can be done using the same construction method as for changing the bottom width described above. That is, by cutting the end of the uppermost side component 5' to a predetermined width, the height of the side 2 can be set arbitrarily. It should be noted that since the side component 5' and the bottom component 5 have the same form, the same parts are given the same reference numerals and dots and their explanation will be omitted.

〔Effect of the invention〕

The hull structure of the present invention configured as described above allows the bottom and sides to be constructed using hollow extruded shapes, so the structural members can be simplified and processed more easily than conventional ship structural members. In addition, the number of welding points during assembly can be reduced, and the workability of welding work is improved by making the welding points flat, and distortion caused by welding is eliminated. As a result, it is possible to reduce labor and time in assembly work, shorten delivery time, and improve energy savings. Moreover, since the bottom and side of the ship are made of double-walled hollow members, it is possible to improve the ship's performance by providing latent buoyancy, and it also maintains safety even in the event that cracks or damage occur on the inner or outer surface. In addition, the hollow space can be used to install hydraulic piping, electrical wiring, etc., or storage tanks for fuel oil, machine oil, drinking water, etc., making it possible to use the limited space inside the ship. Furthermore, by providing a plurality of reinforcing ribs 5j, . When the inside is used as an oil tank or oil piping, it has excellent effects such as increasing the heat exchange rate between oil and seawater and efficiently cooling the oil, and its utility value is remarkable.
