Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a watertight structure of a fastening portion of a cabin component in a hull of a fishing boat, etc., and is particularly concerned with a watertight structure of a fastening portion of a cabin component in a hull of a fishing boat, etc. The interior of the cabin is completely protected from rainwater, seawater, etc.

[Conventional technology]

Recently, aluminum materials, which have excellent corrosion resistance and are lightweight, have been used for the cabins of ships, such as fishing boats, and are assembled using a welded structure. Dissimilar metal members cannot be connected by welding, and there is a problem that electrochemical reactions will occur and corrosion will occur if they come into direct contact with each other, so an aluminum cabin configuration is used, as shown in Figure 6. An insulating material c is interposed between the member a and a base member b made of steel, copper, etc., and the member is fastened by a fastener d such as a screw.

[Problem that the invention seeks to solve]

However, in the conventional fastening structure of this type, the fastening tool d is exposed to the outside, so there is a risk that seawater, etc. may enter the cabin through the fastening tool d, and the aluminum component may be exposed to seawater. There were problems such as corrosion and inability to maintain water solubility.

[Means for solving problems]

This invention has been made in view of the above circumstances, and is made of aluminum having a mounting part with a substantially U-shaped cross section that is open at the top for use with a component, and a connecting member protruding from a protrusion from the bottom of the mounting part. In the case where an insulating material is interposed between a connecting member made of aluminum and a base member that is made of a material different from that of the connecting member and is connected by a fastener, The outwardly protruding end of the fastener is surrounded by a long covering that engages with the engaging portion, and a watertight filler is filled between the covering and the fastening. The present invention proposes a watertight structure for a component fastening part characterized by having a watertight structure, or an intervening part.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Polyurethane may be foamed and injected between them, and it is sufficient that the space between the covering body 9 and the bolt head 7a' is filled and sealed as a result. Further, without filling the entire inside of the covering body 9 with the watertight filler 8, it is also possible to fill only the vicinity of the engaging portion 10a like a sealing material and to completely seal only both ends. Note that 4a is a drain hole formed in the attachment part 4.

As described above, the outwardly protruding end portion of the fastener 7 that fastens and fixes the connecting member 3 and the base member 2, that is, the bolt head 7a', is surrounded by the covering member 9, and the covering member 9 and the bolt head A watertight filler 8 is placed between the part 7a' and the part 7a'.
By filling and sealing many fasteners 7
Since the externally exposed portions of the screws can be completely and quickly covered, there is no possibility of seawater or the like entering the fastening portions.

Note that a draining piece 9' is provided at the lower end of the covering 9 and extends downward along the outer surface of the covering 9, so that seawater, rainwater, etc. can be transmitted along the outer surface of the covering 9 to the fastening part side. to prevent attempts to infiltrate the
It is made to fall downward.

FIG. 2a shows a modification of the embodiment shown in FIG. 2. In this case, instead of filling the filler 8 in FIG. Sealing is achieved by interposing a caulking material 8' between them.

3 to 5 show another embodiment of the present invention, and FIG. 3 shows the attachment part 4 of the connecting member 3.
An engaging portion 10b having a circular concave shape is formed at the outer lower end of the connecting leg 5, and an engaging claw 10c protruding outward is formed at the lower end of the outer surface of the connecting leg 5. The circular convex engaging portion 9b is the engaging portion 10.
b, the covering body 9 is rotated counterclockwise using the engaging parts 9b and 10b as fulcrums, and the engaging part 9c provided at the lower end of the covering body 9 is engaged with the tip of the engaging claw 10c. In addition to the structure shown in FIG. 3, in addition to the structure shown in FIG. A support part 11 is formed on the fishing boat floor B' at a position directly below the mounting rib 4', and an interior plate 12 is provided that connects the upper and lower ends to the mounting rib 4' and the support part 11. Covering the end portion, that is, the nut 7b side,
This prevents corrosion of the inwardly exposed portion of the fastener 7 and enhances the aesthetic appearance of the interior of the cabin. Note that the interior board 12 is made of a corrosion-resistant member such as a vinyl board. Further, in the embodiment shown in FIG. 5, an engaging pawl 10e facing the connecting leg 5 is formed at the outer end of the attachment portion 4 of the connecting member 3, and the engaging pawl 10e and the connecting leg 5 are connected to each other. Engaging portions 10f, 10f are formed at the lower end opposing portions, and the covering 9 is inserted from below to form the engaging portions 9 of the covering 9.

〔Effect of the invention〕

As explained above, the watertight structure of the present invention connects the connecting member made of aluminum shapes to which the cabin components are attached, and the foundation member made of dissimilar metals such as steel and standing on the ship. The outwardly protruding end of the fastener to be fixed and fixed is surrounded by a covering, and a watertight filler is filled or sealed between the covering and the fastening tool, so it is particularly protected against wind and rain. Even under adverse conditions such as being exposed to splashes from waves, it is possible to completely prevent seawater, rainwater, etc. from entering the cabin through the fastenings, and since the fasteners are completely covered, The fasteners themselves do not need to be made of expensive materials such as stainless steel with excellent corrosion resistance, and fasteners such as bolts, nuts, or rivets made of ordinary materials can be used, and they are easy to assemble. Even if multiple fasteners are arranged at uneven intervals and vertically shifted, many fasteners can be quickly and easily fixed with one covering.
It has excellent effects such as being able to securely cover the fastener and easily construct a waste-free fit by using a cover with an arbitrary cross-sectional shape depending on the installation height of the fastener. Since it is covered with a covering, the design value of the appearance can be increased, and its utility value is remarkable. Note that this invention can be applied to structures other than ships, if necessary.
