Description

[Detailed Description of the Invention] This invention relates to fiber reinforced plastics (hereinafter referred to as
This relates to the improvement of the roof structure of ships made of FRP (FRP).

Conventionally, in the roof structure of a ship made of FRP, the roof was placed on the upper end of a peripheral wall such as a bridge, and the peripheral edge of the roof was made to protrude outward from the peripheral wall. This structure had the disadvantage that the lower surface of the part that protruded outward from the peripheral wall was visible from the outside, and that this part was unsightly because it was a non-formed surface of the FRP. In addition, to eliminate this drawback, a structure has been adopted in which the top edge of the surrounding wall and the edge of the roof are overlapped with each other facing outward, and a U-shaped trim material is attached that wraps around both ends, but in this structure, the plane of the edge of the roof The drawback was that it took a lot of effort to bend it to fit the shape.

The present invention has been made to overcome these conventional drawbacks, and provides a structure that has an excellent appearance and is easy to install. That is, this invention bends the upper end of the peripheral wall of a bridge or the like outward, then bends its tip further upward, and overlaps the downwardly bent portion of the roof's peripheral edge with the outer surface of this upwardly directed portion to join the two, thereby forming the peripheral wall. A cover plate is attached to the cover plate so as to constitute an upward extension thereof, and its upper end is in contact with the inner surface of the roof, and there is a space for wiring, etc. between the bent part of the peripheral wall, the peripheral edge of the roof, and the cover plate. is formed.

Embodiments of the present invention will be described below with reference to the drawings. In Figures 1 and 2, 1 is the hull, 2
is a bridge, and the peripheral wall 3 and roof 4 of bridge 2
The joint portion with the main body is constructed as shown in FIG. That is, the upper end of the peripheral wall 3 is bent outward (projection 31), and its tip is bent upward to form the edge 32, and the peripheral edge of the roof 4 is bent downward to form the edge 42. This edge 42 is overlapped on the outside of the edge 32 and fixed together with the trim material 7 by tightening with screws 6. The trim material 7 may be extruded from aluminum into the cross-sectional shape shown in the figure, and a covering material 7 is provided on the outside of the trim material 7 to cover the head of the screw 6 and to make the external shape smooth.
0 is installed. This covering material 70 may be made of extruded plastic material such as vinyl chloride. Further, the lower end of the trim material 7 covers the lower end of the edge 42, thereby covering and hiding the end face (end) of the FRP material. A waterproof material such as a silicone sealant may be filled between the lower end of the edge 32 and the lower end of the trim member 7 to ensure complete watertightness. Further, instead of the trim material 7, a colored tape may be applied to cover the end face of the edge 42 and used as an accent line. Although FIG. 3 shows only the cross section of one side, the cross-sectional shape of other parts of the peripheral wall is also the same. Therefore, the trim material 7 is continuously provided so as to surround the entire periphery of the roof 4.

With this structure, the peripheral edge of the roof has a good appearance because the non-shaped surface of the plate is not exposed to the outside, and no particularly difficult work is required to process it. In addition, since the overlapping portions of both plates are oriented vertically, it is difficult for water to enter, making it easy to waterproof.

A core material 41 made of polyvinyl chloride foam is interposed between the FRP plates in a portion other than the peripheral edge of the roof 4 to increase rigidity. Furthermore, a leather lining 5 is adhered to the inner surfaces of the roof and the peripheral wall 3, and a cover plate 9 is attached to the connecting portion between the two. This cover plate 9 is
It is fixed by tightening screws 91 to the mounting base 8, which is a square piece fixed with FRP covering material 81, and serves as a cover for the connection to the inside of the bridge. Since an outwardly directed protrusion 31 is formed at the upper end of the peripheral wall 3, a space 10 is formed between it and the roof 4, through which electrical wiring 11 can be passed.

As explained above, in this invention, the upper end of the side wall of a bridge etc. and the peripheral edge of the roof are made to protrude outward and the vertical edges of the two are overlapped and combined, and the irregular surface of the roof is connected to the outside. Since it is not exposed to water, it has a good appearance and is easy to process. Another advantage is that a space for wiring is formed inside the periphery of the roof.
