Description
本発明は、自動車運搬船に関する。
The present invention relates to a car carrier.
自動車運搬船では、船殻内に複数の車両甲板が配置されるため、船殻の断面形状が背の高い略矩形状となる。このような自動車運搬船では、船体の横傾斜時に船殻が捩じられて船殻の断面形状が菱形に変形するラッキング変形が大きくなり、このラッキング変形により構造的不連続部に疲労損傷が発生する場合がある。そこで、このラッキング変形を抑制するために、種々の対策が講じられている。
In a car carrier, since a plurality of vehicle decks are arranged in the hull, the cross-sectional shape of the hull is a tall, substantially rectangular shape. In such a car carrier, the hull is twisted when the hull is tilted, and the racking deformation in which the cross-sectional shape of the hull is deformed into a diamond shape increases, and this racking deformation causes fatigue damage to structural discontinuities. There is a case. Therefore, various measures are taken to suppress the racking deformation.
一般的に、ラッキング変形に対する対策としては、船殻の船側外板に沿って上下方向に延びる大きな隔壁（いわゆる、ディープウェブフレーム）が船長方向に複数配列される。さらに、特許文献１には、そのディープウェブフレームをボックス状とすることによって、船殻の船側外板からのディープウェブフレームの突出代を小さくすることが提案されている。これは、船長方向の交通性を保ちつつ、ウェブフレームの剛性の低下を防ぐためである。
Generally, as a countermeasure against racking deformation, a plurality of large bulkheads (so-called deep web frames) extending in the vertical direction along the ship side skin of the hull are arranged in the ship length direction. Further, Patent Document 1 proposes that the protrusion of the deep web frame from the ship side outer plate of the hull is reduced by making the deep web frame into a box shape. This is to prevent a decrease in the rigidity of the web frame while maintaining the ship direction traffic.
しかしながら、特許文献１に開示された自動車運搬船では、ラッキング変形を抑制するのに必要な強度を得るために、ディープウェブフレームの下部が幅の大きな隔壁に連結されている。このため、この隔壁の上端部よりも低い位置に車両甲板が配置される場合に、その隔壁に自動車通過用の開口を設け、その開口を通じて自動車を走行させて自動車の積み付けおよび積み降ろし（荷役）を行う必要がある。それ故に、荷役の効率が悪いという問題がある。
However, in the car carrier disclosed in Patent Document 1, the lower part of the deep web frame is connected to a large partition wall in order to obtain the strength necessary to suppress racking deformation. For this reason, when the vehicle deck is disposed at a position lower than the upper end portion of the partition wall, an opening for passing the vehicle is provided in the partition wall, and the vehicle is driven through the opening to load and unload the vehicle (loading / unloading). ) Is necessary. Therefore, there is a problem that the efficiency of cargo handling is poor.
そこで、本発明は、ラッキング変形を抑制でき、かつ、自動車の積み付けおよび積み降ろしを効率的に行うことができる自動車運搬船を提供することを目的とする。
Therefore, an object of the present invention is to provide a car carrier that can suppress racking deformation and can efficiently load and unload cars.
前記課題を解決するために、本発明の自動車運搬船は、上甲板、二重底および一対の船側外板を含む船殻と、前記船殻内に配置された複数の車両甲板と、前記一対の船側外板の内側面に沿って上下方向に延び、下部が前記二重底と結合され、上部が前記上甲板と結合されたボックス状の一対の側部構造体と、前記一対の側部構造体同士を橋架するように前記上甲板の上面に沿って船幅方向に延びる上部構造体と、を備える、ことを特徴とする。
In order to solve the above problems, an automobile carrier of the present invention includes a hull including an upper deck, a double bottom and a pair of ship side skins, a plurality of vehicle decks disposed in the hull, and the pair of A pair of box-shaped side structures that extend in the vertical direction along the inner side surface of the ship side skin, the lower part is coupled to the double bottom, and the upper part is coupled to the upper deck, and the pair of side structures And an upper structure extending in the ship width direction along the upper surface of the upper deck so as to bridge the bodies.
上記の構成によれば、二重底の両端部から立ち上がるボックス状の側部構造体の上部同士が上部構造体で連結されるため、高強度の枠構体を形成することができる。それ故に、前述の船殻の断面形状が菱形に変形するラッキング変形を抑制することができる。しかも、上部構造体は上甲板上にあるため、船殻内の二重底から上甲板までの空間は広く開放したままとすることができる。従って、自動車の積み付けおよび積み降ろしの際に自動車の走行に障害となるものがなく、自動車の積み付けおよび積み降ろしを効率的に行うことができる。
According to the above configuration, since the upper parts of the box-shaped side structures rising from both ends of the double bottom are connected by the upper structure, a high-strength frame structure can be formed. Therefore, the racking deformation in which the aforementioned cross-sectional shape of the hull is deformed into a diamond shape can be suppressed. Moreover, since the upper structure is on the upper deck, the space from the double bottom to the upper deck in the hull can be kept wide open. Therefore, there is no obstacle to the traveling of the automobile when the automobile is loaded and unloaded, and the loading and unloading of the automobile can be performed efficiently.
前記上部構造体は、ボックス状であってもよい。この構成によれば、側部構造体および上部構造体が存する領域では船殻の全周に亘って二重殻が構成される。これにより、船体横断面の捩じり剛性を高めることができる。その結果、ラッキング変形の原因となる船殻の捩じり変形を低減させることができる。また、上部構造体内に、通常は居住区画内に設けられる各種貯蔵物の倉庫類を設ければ、居住区画の占有面積を減少させることができ、上部構造体を採用したことによる自動車運搬船全体の重量の増加を低減させることができる。
The upper structure may be box-shaped. According to this configuration, a double shell is formed over the entire circumference of the hull in the region where the side structure and the upper structure exist. Thereby, the torsional rigidity of the hull transverse section can be increased. As a result, torsional deformation of the hull that causes racking deformation can be reduced. Also, if warehouses for various storages usually provided in the living compartment are provided in the upper structure, the occupied area of the living compartment can be reduced, and the entire car carrier by adopting the upper structure can be reduced. The increase in weight can be reduced.
前記一対の側部構造体の双方は、ステアケーシングまたはベントトランクであってもよい。あるいは、前記一対の側部構造体の一方はステアケーシングであり、他方はベントトランクであってもよい。これらの構成によれば、通常の自動車運搬船に設けられるステアケーシングまたはベントトランクを合理的に利用して、上記の効果を得ることができる。
Both the pair of side structures may be steer casings or bent trunks. Alternatively, one of the pair of side structures may be a steer casing, and the other may be a vent trunk. According to these configurations, the above-described effects can be obtained by rationally using a steer casing or a vent trunk provided in a normal car carrier.
前記一対の側部構造体および前記上部構造体は、船長方向において前記船殻の中央領域内に配置されていてもよい。この構成によれば、上記効果がより高まり、船長方向における側部構造体および上部構造体の長さが短くても、ラッキング変形を十分に抑制することができる。
The pair of side structures and the upper structure may be arranged in a central region of the hull in the ship length direction. According to this configuration, the above effects are further enhanced, and racking deformation can be sufficiently suppressed even when the length of the side structure and the upper structure in the ship length direction is short.

各側部構造体４は、船側外板２３の内側面に沿って上下方向に延びている。側部構造体４の下部は二重底２２と結合され、上部は上甲板２１と結合されている。本実施形態では、側部構造体４の下部が直接的に二重底２２に結合されているが、図３に示すように、側部構造体４の下部は、バラストタンク９などを介して二重底２２に結合されていてもよい。
Each side structure 4 extends in the vertical direction along the inner surface of the ship-side outer plate 23. The lower part of the side structure 4 is connected to the double bottom 22, and the upper part is connected to the upper deck 21. In the present embodiment, the lower part of the side structure 4 is directly coupled to the double bottom 22, but as shown in FIG. 3, the lower part of the side structure 4 is connected via a ballast tank 9 or the like. It may be coupled to the double bottom 22.
各側部構造体４は、ボックス状であり、船長方向において互いに対向する前壁および後壁と、船側外板２３と対向する内壁を含む。例えば、側部構造体４の双方は、ステアケーシングまたはベントトランクである。ステアケーシングとは、車両甲板同士および一番上の車両甲板と上甲板をつなぐ階段を取り囲むボックス状の区画であり、ベントトランクとは、各車載スペース（車両甲板同士の間のスペースおよび一番上の車両甲板と上甲板の間のスペース）の換気を行うための空気の通路となるボックス状の区画である。あるいは、側部構造体４の一方がステアケーシングであり、他方がベントトランクであってもよい。
Each side structure 4 is box-shaped, and includes a front wall and a rear wall that face each other in the captain direction, and an inner wall that faces the ship-side outer plate 23. For example, both side structures 4 are steer casings or vent trunks.

Alternatively, one of the side structures 4 may be a steer casing and the other may be a vent trunk.
二重底２２内には、側部構造体４の前壁および後壁と対応する位置に、仕切り板５が設けられている。なお、仕切り板５は、側部構造体４の前壁および後壁と対応する位置以外にも、所定の間隔で設けられる。

And the continuity of the structure can be maintained.
以上説明したように、本実施形態の自動車運搬船１では、二重底２２の両端部から立ち上がるボックス状の側部構造体４の上部同士が上部構造体６で連結されるため、高強度の枠構体を形成することができる。それ故に、ラッキング変形を抑制することができる。しかも、上部構造体６は上甲板２１上にあるため、船殻２内の二重底２２から上甲板２１までの空間は広く開放したままとすることができる。従って、自動車の積み付けおよび積み降ろしの際に自動車の走行に障害となるものがなく、自動車の積み付けおよび積み降ろしを効率的に行うことができる。
