Abstract

(57) [Summary] [Purpose] In the cargo hold structure of a cargo ship that transports solid bulk cargo such as coal, cereals, ores, and earth and sand. The purpose is to prevent the solid bulk cargo from accumulating in the gap and to secure a large cargo hold volume and a large load capacity. A U-shaped vertical corrugated stiffener 4 is provided between the top side tank bottom plate 6 and the bilge hopper top plate 3 inside the ship side skin 1. A cargo hold structure for a bulk cargo ship, characterized in that a bulk cargo is prevented from accumulating between the ship side skin 1, the top plate 3 of the bilge hopper, and the ship side skin stiffener.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cargo hold structure of a cargo ship that transports solid bulk cargo such as coal, cereals, ores and earth and sand.

[0002]

[Prior art]

 Conventionally, in the cargo hold structure of this type of bulk carrier, as shown in FIGS. 2 and 3, the bilge hopper top plate 33 and the top side tank bottom plate 32 on the inner surface of the ship side outer plate 31 are shown. A structure in which a transverse rib 34 with a face material 35 is welded between them, and a tripping bracket 36 is fixedly provided between the transverse ribs 34, or an inner side of a ship side outer plate 31 and a top plate of a bilge hopper. It is known to have a double hull structure in which a vertical partition wall 38 is fixed between the top plate 33 and the topside tank bottom plate 32.

[0003]

[Problems to be solved by the device]

 In the former of those described in the prior art, although the volume of the bulk cargo freight can be secured sufficiently large, the bulk cargo 37 is placed at the position where the horizontal rib 34 with the face material 35 abuts the top plate 33 of the bilge hopper. The accumulated bulk cargo requires a great deal of labor to be removed, or if it is not completely removed, it will be mixed with the rear cargo and the cargo will be mixed, resulting in a commercial value of the rear cargo. Had the problem of lowering the

Further, in the latter case, although the cargo does not stay, the volume of the cargo hold is extremely reduced, and there is a problem that the weight of light coins of the ship is increased and the loading amount is decreased.

The present invention has been made in view of such problems of the conventional technology, and an object of the invention is to secure a large cargo hold volume and a large load amount, and to carry a bulk cargo. The purpose is to provide a cargo hold structure that does not accumulate.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the shape of the cargo hold of the bulk carrier in the present invention is the inside of the outer shell of the ship, and has a U-shaped vertical direction between the top side tank bottom plate and the bilge hopper top plate. Type corrugated stiffeners are arranged so that bulk cargo does not accumulate between the outer shell of the ship, the top plate of the bilge hopper, and the vertical corrugated stiffeners. Is.

For the same purpose, instead of the U-shaped vertical corrugated stiffener, a trapezoidal vertical corrugated stiffener that forms a divergent space toward the inside of the cargo hold is formed. Material may be provided.

[0008]

[Action]

 The vertical U-shaped or trapezoidal vertical corrugated stiffener is a reinforcing material for the outer shell of the ship, and prevents bulk cargo from accumulating on the top plate of the bilge hopper.

[0009]

【Example】

 Examples will be described with reference to the drawings. In FIG. 1, the structure of the cargo hold of the bulk cargo ship is the inside of the cargo hold 7 of the outer shell 1 of the ship, and is between the top side tank and the bottom plate 6 inclined downwardly toward the outer shell 1 of the ship. And a vertical U-shaped corrugated stiffener as a reinforcing material for the ship side skin 1 between the top plate 3 of the bilge hopper having a downward slope from the ship side skin 1 toward the inside of the cargo hold 7. Set up.

[0010]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

The stiffener of the outer shell of the ship is made of a U-shaped vertical corrugated steel plate, and the top plate of the bilge hopper has a downward slope at an angle of about 45 degrees toward the bottom plate of the cargo hold. As a result, the bulk cargo does not stay on the top plate of the bilge hopper, and the cargo hold volume and load capacity are not reduced compared to those of conventional bulk carriers.

Claims (1)

[Scope of utility model registration request] 1. A cargo hold structure for a cargo ship that transports solid bulk cargoes such as coal, grains, ores, and sand, which is inside a side plate of a ship, and which is a top side tank bottom plate and a top of a bilge hopper. A U-shaped vertical corrugated stiffener is placed between the plates to prevent bulk cargo from accumulating between the outer plate of the ship and the top plate of the bilge hopper, and the stiff plate of the ship side. The cargo hold structure of a bulk carrier that is characterized by
