Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a cross-sectional structure of a hull, and more particularly, to a sea deck which constitutes a part thereof.

[Conventional technology]

In a ship, seawater driven into the exposed deck is guided to both sides by arcs, trapezoids, and other cambers of various shapes, and then discharged to the outside.

In particular, a ship's hull may be provided with a sea shield deck over the work space to protect the work space from wind, rain, and waves.This sea shield deck, like other exposed decks, must be installed from both sides. Discharging seawater.

As a cross-sectional structure of a ship having such a sea deck, for example, one shown in FIG. 6 is known.

In the figure, reference numeral 21 indicates the starboard side, and reference numeral 22 indicates the port side. An opening 23 is provided for work on the starboard side 21.

An upper deck 24 is bridged between the starboard side 21 and the portside 22.
A work space S is formed above the upper deck 24 and
A workbench 25 is provided on the right side of 24. Starboard side 21
Between the upper part 21A of the opening 23 and the upper end 22A of the port side 22 is laid a sea deck 26 having a camber C formed,
The sea-blocking deck 26 is provided to protect against wind and rain and waves when working on the upper deck 24, and is arranged in a certain range behind the forehand deck (not shown).

Further, water discharge ports 27, 27 are provided on the starboard side 21 and the port side 22 above the sea-blocking deck 26, respectively. Therefore, the opening 23 is located immediately below the water discharge port 27 provided on the starboard side 21.

Then, the waves struck on the sea deck 26
Guided to both sides 21 and 22 by Camber C of
It is discharged to the outside via 27.

[Problems to be solved by the device]

However, in the above-mentioned cross-sectional structure of the hull, the opening 23 for the working space S is provided on the starboard side 21 at the water outlet.
Since it is located immediately below 27, the seawater discharged from the water outlet 27 to the outside of the starboard side 21 enters the work space S through the opening 23 on the starboard side 21 and deteriorates the work environment.

The present invention was made in order to solve the above-mentioned problems, and the purpose thereof is that seawater discharged from the discharge port to the outside of the port side is passed through the opening on the port side to the working space under the sea deck. It is an object of the present invention to provide a cross-sectional structure of a ship that prevents intrusion.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention forms an opening on one port side, and bridges a sea-blocking deck between a part on one port side on the upper side of this opening and the other port side, In a cross-sectional structure of a hull having a water outlet on the upper side of the sea deck, part or all of the sea deck is inclined downward from only one port side to the other port side, and the other port side. It has a water outlet on the upper side of the barge deck.

[Action]

In the present invention, part or all of the sea-block is sloped downward from one port side to the other port side only, so seawater driven onto the sea-block will open on the sea-block. It flows down from one port side with a part toward the other port side, and is guided to the outside of the port side via the water outlet on the other port side.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

A cross-sectional structure of a hull according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4.

In the figure, 1 is a starboard side, and an opening 2 is provided on the starboard side 1.
Is provided, and the opening 2 can be shielded if necessary. 3 is a port side, and a water discharge port 4 is provided at an upper end 3A of the port side 3. No water outlet is provided at the upper end 1A of the starboard side 1.

An upper deck 5 is laid between the starboard side 1 and the portside 3
A work space S is formed above the upper deck 5, and a work table 6 is provided on the right side portion of the upper deck 5. Starboard side 1
Between the upper part 1A of the opening 2 of the ship and the port side 3
The sea-blocking deck 7 is provided to protect against wind and rain and waves when working on the upper deck 5, and is arranged behind the foreclosure deck 8 over a certain range.

And the above-mentioned water discharge port 4 is located in the upper part of the port side 3 above the sea-blocking deck 7, and all of the sea-blocking deck 7 is on the starboard side 1.
From the port side to the port side 3, the line is inclined downward in a straight line.

In this embodiment, however, since the entire sea-blocking deck 7 is inclined downward from the starboard side 1 to the port-side 3, the seawater that has been driven onto the sea-blocking deck 7 is It flows upward from the starboard side 1 toward the portside 3, and is guided to the outside of the portside 3 via the water discharge port 4 of the portside 3. Even if the seawater is discharged to the outside of the port side 3, the seawater does not enter the work space S because the opening is not provided.

As a result, seawater does not flow down from the sea-block deck 7 along the starboard side 1, and even if there is an opening 2 on the starboard side 1, the seawater discharged from above the sea-block deck 7 as described above is used as the work space S.
It is possible to prevent the water from being flooded, and thus improve the working environment.

In addition, in this embodiment, all of the sea-blocking deck 7 is inclined downward from the starboard side 1 to the port-side 3, but as shown in FIG. 5, the sea-blocking deck 17 is connected to the starboard-side 1 It is also possible to form a horizontal portion 17B and a portion 17A that is inclined downward from the port side 3 to the port side 3.

Further, in the present embodiment, the case where the opening portion 2 is provided on the starboard side 1 has been described, but when the opening portion is provided on the port side 3, the blocking deck 7 moves from the port side 1 to the starboard side 3. It may be configured so as to be inclined downward.

Further, in the present embodiment, the sea shield deck 7 is linearly downwardly inclined, but it may be curved and downwardly inclined.

Further, in the present invention, as shown in the above-mentioned embodiment, the wave shield deck is inclined only from one port side toward the other port side, and an inclined surface descending from the other port side toward the one port side. Does not include.

[Effect of device]

As described above, according to the cross-sectional structure of the hull according to the present invention, a part or all of the sea deck is inclined downward only from one port side to the other port side, so that the sea deck is The seawater that has been hammered up flows from the port side with the opening toward the port side on the other side on the barge deck, and is guided to the outside of the other port side via the water discharge port on the other port side. Even if seawater is discharged to the outside of the other port side, seawater does not enter the working space because the opening is not provided on the other port side.

As a result, seawater discharged from above the sea-block deck as described above does not flow down from the sea-block deck along one of the port sides with an opening, and even if there is an opening on one port side, seawater is not available in the work space. Can be prevented from inundating, and the working environment can be improved.
