Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer shell in a superstructure of a ship such as a high speed ship.

[0002]

2. Description of the Related Art An outer shell of a conventional superstructure for a high-speed ship has a structure as shown in FIGS.

That is, a plurality of panel members 50 serving as ceiling walls and side walls, a plurality of transverse beam members (also referred to as small bones) 51 integrally formed inside the panel members 50, and these transverse beam members 51. Panel member 5 so that it intersects at a right angle to
A plurality of vertical girder members 52 having a T-shaped section provided inside 0
It is composed of

The panel member 50, the horizontal girder member 51 and the vertical girder member 52 are made of aluminum.
The panel members 50 and the stringer members 52 are joined together by welding.

[0005]

In the outer shell of the superstructure of the high-speed ship, the panel members 50 are joined to each other and the panel members 50 and the stringer members 52 are joined to each other by welding. Thermal distortion occurs in the panel member 50, and much time and cost are required to remove this thermal distortion.

[0006] Therefore, an object of the present invention is to provide an outer shell body in a superstructure of a ship which can solve the above problems.

[0007]

Means for solving the problems of the present invention is to mount a plurality of cross beam members and stringer members at right angles to each other, and to attach the cross beam members and stringer members respectively. On one side, a flat plate-shaped supporting portion for supporting the end portions of the panel member serving as the ceiling wall and the side wall is formed, and this panel member is fixed to the supporting portion with an adhesive, and the horizontal girder member, the vertical girder member, and At least the panel member among the panel members is formed of a thermosetting resin-based composite material.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to FIGS. As shown in the perspective view of FIG. 1, an outer shell body 2 in a superstructure of a boat 1 according to an embodiment of the present invention forms a cabin 3 and is installed on a deck 5 of a boat body 4.

As shown in the sectional view of FIG. 2 and the perspective view of FIG. 3, the outer shell body 2 is made of aluminum and is arranged in the fore-and-aft direction 6. A vertical girder member 8 welded (or fastened with bolts) so as to be orthogonal to the horizontal portion 7A of the girder member 7, and the horizontal girder member 7 and the vertical girder member 8 are respectively flanges 10 and 11 and these flanges 10. , 11 and the webs 12 and 13 which are erected from the central portion thereof are formed in an inverted T-shape in cross section.

Further, at the upper ends of the webs 12 and 13 of the horizontal girder members 7 and the vertical girder members 8, FRP (thermosetting resin-based composite material) which becomes the top wall and the side wall of the outer shell 2 are formed. Support members 16A, 1 for supporting the corners of the panel member 15
6B, each support member 16A, 16B includes a respective web 12, 13 of each transverse girder member 7 and longitudinal girder member 8.
Support portions 17a, 1 formed integrally so as to be orthogonal to
7b and an abutting portion 18 formed on an extension of each of the webs 12 and 13 and having a thickness lower than that of the panel member 15.
The panel member 15 is formed in an inverted T-shape in cross section from a and 18b, and the side surface of the panel member 15 is fixed to the abutting portions 18a and 18b with an adhesive (for example, epoxy resin) 20.

A seal material (for example, silicon rubber or the like is used) 21 is provided on the side surface of the panel member 15 and each of the abutting portions 18a and 18b where they are adhered to each other, thereby preventing water from entering the outer shell 2. In addition, the butted portions 18a and 18b are covered.

Further, as shown in the sectional view of FIG. 4, at a position where the vertical girder member 8 is not provided, the panel member 15 is supported between the pair of lateral girder members 7, and the side surface of the panel member 15 at this position. Is the butted portions 18a, 18 of the cross beam member 7.
It is fixed to b with an adhesive 20.

In order to manufacture the outer shell body 2 having such a structure, first, the horizontal girder member 7 and the vertical girder member 8 are attached to the supporting member 16.
A and 16B are manufactured together, the transverse girder members 7 are arranged side by side in the bow-stern direction 6 on the deck 5, and the longitudinal girder members 8 are provided at predetermined positions between the transverse girder members 7 (the center of the horizontal portion 7A in the figure). Weld.

Subsequently, the panel members 15 are supported by the support portions 17a and 17b so that the corner portions of the panel member 15 are brought into contact with the support portions 17a and 17b of the horizontal girder member 7 and the vertical girder member 8, respectively. The side surface of the member 15 is fixed to the abutting portions 18a and 18b with the adhesive 20, and the sealing material 21 is applied to complete the production.

According to the embodiment of the present invention, the support members 16A, 16 provided on the horizontal girder member 7 and the vertical girder member 8 are provided.
Since the abutting portions 18a and 18b of B and the side surface of the panel member 15 are fixed to each other with the adhesive 20, thermal distortion does not occur in the panel member 15 when the outer shell body 2 is manufactured,
Therefore, it is not necessary to correct the thermal strain generated by welding in the related art, so that the outer shell body 2 can be easily manufactured, and the manufacturing time and manufacturing cost can be reduced.

In the above embodiment, the panel member 15 is used.
Is formed of FRP, but is not limited to this, and may be formed using, for example, a honeycomb structure of aluminum.

[0017]

As is apparent from the above description, according to the present invention, the vertical girder members are attached to the plurality of lateral girder members, and the end portions of the panel member serving as the top wall and the side wall are attached to these lateral girder members and vertical girder members. Since a flat plate-shaped supporting portion for supporting the panel member is formed and the panel member is fixed to the supporting portion with an adhesive, no thermal strain is generated in the panel member, and therefore the correction is unnecessary. The shell body can be easily manufactured, and the manufacturing time and manufacturing cost can be reduced.
