Description

[Detailed explanation of the invention] This invention is applicable to the cabin of a vessel such as a fishing boat,
It is related to the watertight structure of the connecting parts of hollow panels that make up the ceiling and side walls of hatch covers, bunt trucks, and other structures. It is characterized by being able to protect the

That is, the gist of this invention is to form a longitudinal hollow part between the hollow panels that are connected to each other, and to surround the outdoor connecting part from the connecting rib of one of the hollow panels in this hollow part. It is formed with a drainage gutter that protrudes outward, and protects the indoor side by blocking rainwater, etc. that tries to enter the indoor side from the hollow panel connection part. It is an object of the present invention to provide a watertight structure of a hollow panel connecting portion characterized by the following features.

Examples of this invention will be described below based on the drawings.

FIG. 1 shows a schematic perspective view of a fishing boat B equipped with a cabin A having a watertight structure according to this invention. ，
It consists of 1... In this case, as shown in FIG. 2, the hollow panel 1 constituting the ceiling section has two opposing plates 2 and 3 connected to each other by a connecting rib 4 provided between these plates 2 and 3 for reinforcement. , 5 and 6
At the connecting end of the hollow panel 1 (the left end in FIG. 2), a groove 7 with the connecting rib 4 as a wall is formed longitudinally, that is, along the longitudinal direction of the hollow panel 1. At the same time, an arcuate ridge 9 is formed at the tip of the extension part 8 on the outdoor side constituting the groove 7 to fit into an arcuate groove 12 provided in an adjacent hollow panel 1, which will be described later. At the tip of the engagement piece 10 that forms a part of the groove 7 on the inside, the indoor side plate 3 of the adjacent hollow panel 1 is attached.
A hook portion 11 is formed which engages with a stepped protrusion 13 protruding from the connecting end of. Further, an arcuate groove 12 to be fitted with the arcuate protrusion 9 is formed on the outdoor side of the other connecting end (the right end in FIG. 2), and the engagement piece 10 is formed on the indoor side. A protruding piece 13 is provided to protrude in sliding contact with one side, and a hook part 11 provided at the tip of the engaging piece 10 can be hooked onto a step 13' provided at the base of the protruding piece 13. be. A longitudinal hollow portion 14 is formed by the groove 7 of the hollow panels 1, 1 which are connected to each other and the right-end connecting rib 6 of the adjacent hollow panel 1. Further, within the hollow portion 14, a concave circle is formed outward from the connecting rib 6 to surround the outdoor side connecting portion, that is, the fitting portion between the arcuate protrusion 9 and the arcuate groove 12. An arc-shaped drainage gutter portion 15 is provided in a longitudinally protruding manner. Of course, the cross-sectional shape of the drain gutter portion 15 is not limited to an arc shape, but may be arbitrary.

When the hollow panel 1 configured as described above fits the arc-shaped ridge 9 on the left end side into the arc-shaped groove 12 on the right end side of the adjacent hollow panel 1, the ridge 9 and the groove 12 are connected to each other. While rotating between the two according to the circular arc shape, the engaging piece 10 is pushed into sliding contact with the inside of the protruding piece 13, and this engaging piece 1
The left and right hollow panels 1, 1 are connected by fitting the hook portion 11 of 0 into the stepped portion 13' of the projecting piece 13, and the hollow panels of the same shape are connected in either direction to form a cabin. The ceiling of A can be constructed. Incidentally, if necessary, the engagement portion between the hook portion 11 and the stepped portion 13' may be filled with caulking material 16.

On the other hand, the covering body 1 has a chamber 17 communicating with the hollow part 14 at the end in the longitudinal direction of the hollow panels 1, 1, which constitute the ceiling part as described above.
8 is attached through an O-ring 19 in an air- and water-tight manner. (See FIG. 3) A drain hole 20 that opens outward is provided at the lower end of the covering 18.
Rainwater, etc. sent to the chamber 17 through the drainage gutter section 15 in the hollow section 14 is discharged to the outside through the drain hole 20. That is, the intermediate panel 1 prevents seawater, rainwater, etc. that try to enter the cabin through the gap in the fitting part between the arcuate ridge 9 and the arcuate groove 12, which are the connecting parts on the outdoor side of the hollow panels 1, 1... , 1 in the longitudinal direction of the hollow panels 1, 1,... After flowing into the chamber 17 of the covering 18 attached to the end, the water is discharged to the outside through the drain hole 20.

FIGS. 4a and 4b are sectional views of main parts showing another form of the second embodiment of this invention, in which a draining piece 21 is provided protruding from the indoor side surface of the drainage gutter section 15 toward the indoor room. In this case, Fig. 4a shows the drainage gutter section 1.
FIG. 4b shows a case in which a draining piece 21 is formed at the tip of the drain gutter 15, and FIG. By providing such a draining piece 21, seawater, rainwater, etc. that have entered the hollow portion 14 from outside through the gap in the connecting portion can further cross the drain gutter portion 15 and drain into the drain gutter portion 15.
Even if the water leaks through the side of the room and invades the inside of the room, the draining piece 21 can prevent the water from entering.

FIG. 5 is a perspective view of a main part showing a third embodiment of this invention, in which drain holes 22, 22, . It is. Such a drain hole 22,2
By providing 2..., the hollow part 14' composed of the plates 2, 3 and the connecting ribs 5, 6 is communicated with the drain gutter part 15, and this hollow part 14' can be used as a drain gutter. As the drainage capacity of the drainage gutter increases, it also communicates with the hollow part 14', so the pressure difference between the outside air and the hollow part 14 is reduced, and the watertightness of the connection part can be further improved.

Although the above embodiment describes the case where a linear ceiling section is formed, a similar structure and effect can be obtained even when a semicylindrical roof section as shown in Fig. 6 is formed. Providing fine irregularities on the surface of the outdoor board 2 also prevents slipping.
The structure can be applied not only to the cabin of a ship such as a fishing boat, but also to a bunk truck or other general structures (moving or stationary). A similar effect can be obtained for vertical parts such as side wall parts.

As explained above, according to the watertight structure of this invention, the hollow panels can be easily assembled without using means such as welding to form the ceiling or side wall of the structure as appropriate, and the sealing material Since it is possible to construct a structure with an excellent waterproof effect without using any water, its utility value is remarkable.
