本発明は船舶の構造に関するものであり、更に詳しくは
バラ積貨物船の横隔壁の構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of ships, and more particularly to the structure of transverse bulkheads of bulk carriers.
一般に、無包装のバラ状にされた貨物をバラ積貨物と称

兼用船舶である。Generally, unpackaged bulk cargo is called bulk cargo, and a ship dedicated to transporting bulk cargo is called a bulk cargo ship. In this para-loading cargo ship, when it is not loaded with cargo, that is, when it is empty, its legs are shallow because the total weight of the cargo ship is light. If the ship's legs are shallow, there are various problems such as an increase in the shaking of the ship during navigation, an increase in the thrusting impact pressure at the bow and bottom of the ship, and an increase in the wind pressure that the ship receives. In order to prevent this, a suitable amount of ballast is loaded inside the hull of the vessel so that the landing gear is at an appropriate depth. (Seawater is usually used as the ballast.) The vessel on which the above-mentioned ballast is loaded is a cargo and ballast vessel that is provided inside the hull to load bulk cargo.
そして、前述のバラ積貨物船の船舶壁は、船体の長さ方
向に船側外板を有し、横方向は船体の長さ方向に対し直
角方向に配設される横隔壁と称する水密隔壁を有する。The ship wall of the bulk carrier mentioned above has a side skin in the length direction of the ship, and a watertight bulkhead called a transverse bulkhead arranged in a direction perpendicular to the length direction of the ship in the lateral direction. have

配置されている。FIG. 4 is a schematic side view showing a conventional example of such a transverse partition wall. In the figure, 2 is the upper deck, 3 is the double bottom cargo hold, and 4 is the bottom of the ship. The horizontal partition wall 6 is placed across the partition wall to watertightly partition the right side and the left side as shown in the figure.
次に、第５図（ａ）及び（ｂ）を用いて従来の横隔壁の

物の総積ｉ！量が減少する。The horizontal partition wall 7 shown in FIG. 5(a) consists of two opposing steel plates 8.
．． A plurality of reinforcing plates 12 are fixed between 10. This horizontal partition wall 7 has a void 14 (space) surrounded by the steel plates 8 and 10 and the reinforcing plate 12. this(
Although the transverse bulkhead 7 shown in a) is relatively light in weight, the void 14, which is a space, cannot of course carry cargo, so a cargo ship using this transverse bulkhead 7 has a relatively light weight. Product i! quantity decreases.
そこで、積載量を増加させるために第５図（ｂ）に示す

The distance is larger than the distance b, and the thickness t2 of the part d shown in figure (b) is thicker than the plate Kt shown in figure (a) because it has a watertight structure. As a result, there is a problem in that the total weight of the entire transverse bulkhead is heavier in the structure shown in FIG. 3B than in the structure shown in FIG.
本発明は上述従来技術の問題点に鑑みなされたものであ

This is the same as if the length were changed to 2. The same vertical steel plate 30 whose actual length has been reduced to half by the vibration isolator 22
The thickness t of the longitudinal plate 30 can be made thinner (half the thickness) than the conventional plate thickness t2 shown in FIG. 5(b) if it is made of the same material. can. This is because the distance d of the vertical steel plate 30 is halved by providing the vibration isolator 22 at the center of the vertical steel plate 30, and the rigidity of the vertical steel plate 30 is improved. And as explained above,
Since the plate thickness t of this example can be made thinner than that of the conventional one, even considering the weight increase due to the provision of the vibration isolator 22, the overall weight of the transverse bulkhead 20 according to the present invention can be reduced. It can be made lighter than the conventional transverse bulkhead 1G shown in FIG. 5(b).

で貨物の積載量を低減しなくて済む。As explained above in detail and concretely, according to the present invention, since the vibration isolator is provided in the center of the vertical steel plate constituting the horizontal bulkhead,
The thickness of the vertical steel plates can be made thinner than conventional ones, which makes it possible to reduce the weight of the entire transverse bulkhead.Also, since the transverse bulkhead according to the present invention has no voids, it is possible to reduce the weight of the transverse bulkhead. There is no need to reduce the loading capacity.
