Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a gunwale structure for a ship, and particularly to a gunwale structure for a small ship such as a high-speed boat made of light alloy.

[Conventional technology]

In the conventional gunwale structure of a small vessel such as a high-speed boat, as shown in FIG. Because it sticks out from 1,
In order to prevent the ship's side shell 4 from being easily distorted by physical external forces such as being hit by objects, and from the risk of the rope used for holding etc. being cut by the edges of the ship's side shell 4, A round bar 6 is joined to the upper end of the ship's side skin 4. In addition, in order to provide a fender 7 with a semicircular cross section on the side of the ship in order to soften the impact when berthing or to protect the ship's side skin 4 from impact force,
A half-shaped pipe material is joined to the upper part of the ship's side outer plating 4.

[Problem that the invention attempts to solve]

For this reason, there was a problem in that the conventional gunwale structure required time and effort to work.

The present invention attempts to solve these problems and provides a gunwale structure for a ship that integrates the fender and the round bar provided at the upper end of the outer skin of the ship.

[Means for solving problems]

For this reason, in the ship gunwale structure of the present invention, the gunwale part where the upper deck and the ship's side skin are joined is formed of a continuous pipe material in the longitudinal direction, and the ship's side skin plate is connected to the pipe material approximately on the center line below the pipe material. The left and right ends of the upper deck are welded together, and the left and right ends of the upper deck are welded to the pipe material on the right side for the port side pipe material and on the left side for the starboard side pipe material at a position that passes approximately through the center of the cross-sectional circle of the pipe material. It is said that

[Effect]

In the ship gunwale structure of the present invention described above, the outer half of the tube forming the gunwale functions as a fender, and since it is a tube, the upper arc prevents distortion and rope breakage. do.

〔Example〕

The gunwale structure of a ship as an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a central sectional view of a high-speed boat having the structure of the present invention.

The upper deck 1 is located at the center 3 of the cross-sectional circle of the gunwale pipe material 2.
It is welded to the tube 2 from the inboard side near a line passing through the tube 2, and the side skin 4 is similarly welded to the tube 2 near the center line of the lower part of the tube 2.

Portion 5 of pipe material 2 overhanging from the ship's side shell plating
Since the pipe also serves as a fender, there is no need to rejoin a half-shaped tube material on the side outer plate as a fender. Further, the upper part of the tube member 2 has an arcuate shape, which prevents the rope, etc. taken from the inside of the ship to the outside of the ship from being frayed, and also prevents personal injury due to the edge of the upper part of the outside of the ship. In addition, since the number of welding points is reduced, the number of man-hours required for this installation can be significantly reduced compared to conventional ones, and distortion of the hull outer plating 4 and upper deck 1 is reliably prevented by using highly rigid pipe materials. be able to.

[Effect of idea]

As detailed above, the gunwale structure of a ship according to the present invention has a simple structure in which the pipe material is arranged at the joint between the hull outer plating and the upper deck, and the upper deck and the ship's side outer plating are joined to the pipe material. At the same time, a gunwale structure that forms a fender is obtained, and even when the gunwale part is hit by a rope, etc., the outside is a pipe material, so
This has the advantage of providing a gunwale structure with less risk of rope breakage, etc., with fewer man-hours.

Claims (1)

[Scope of utility model registration request] The gunwale section where the upper deck and side shell of the ship are joined is formed of a pipe material that continues in the longitudinal direction, and the ship's side shell plating is welded to the pipe material approximately on the center line below the pipe material, and the port side pipe material A ship's gunwale structure characterized in that the left and right ends of the upper deck are welded to the pipe material at a position passing approximately through the center of the cross-sectional circle of the pipe material on the right side of the starboard side pipe material and on the left side of the starboard side pipe material.
