For example, Patent Document 1 describes a structure in which a plurality of plate-like members are connected to ensure sufficient strength at the bow and stern of a ship. The ship described in Patent Document 1 includes an oblique plate member, an inboard vertical plate member, and a horizontal plate member that are arranged at an angle close to the vertical with respect to the outer plate of the bow portion. In this marine vessel, the slanted plate member is arranged at an angle close to the vertical with respect to the outer plate, so that the load acting from the outer plate can be effectively transmitted to the vertical plate member and the horizontal plate member in the ship. As a result, this ship has a sufficient strength against the load received by the bow.

  By the way, in addition to intensity | strength, it is necessary to satisfy | fill the request | requirement regarding a radar reflective cross section (Radar Cross-Section, RCS), or to provide the structure for flowing a wind in ship. In such a case, for example, the front wall facing the bow side of the structure provided in the upper part of the ship body is arranged so as to be inclined with respect to the bow-stern direction. As a result, there may be an acute angle between the front wall of the structure and the hull outer plate constituting the shore side.

Can be made. Therefore, the stress level generated between the upper structure side wall and the upper structure front wall can be reduced.

  In the ship according to the third aspect of the present invention, in the second aspect, the interposition part may have a third interposition wall that connects the second interposition wall and the upper structure side wall. .

  According to such a structure, the load which works in the direction pressed against the side wall of the upper structure is distributed to the first interposed wall and the third interposed wall via the second interposed wall. Therefore, the deformation of the interposition part can be suppressed. That is, the rigidity of the interposition part can be improved as compared with a structure in which the first interposition wall and the second interposition wall are simply connected.

  Further, in the ship according to the fourth aspect of the present invention, in the third aspect, the interposition part has a distance in the bow-stern direction between the first interposition wall and the third interposition wall on the side wall of the upper structure. You may be away as you get closer.

The bulwark connected may be provided, and the interposition part may be provided at an end of the bow side of the upper structure side wall.

  According to such a configuration, even if the space between the upper structure front wall and the upper structure front wall becomes narrow due to the continuous formation of the upper structure side wall and the bulwark, a narrow space is formed by the interposition part. The region that is formed can be reduced.

  Further, the ship according to the seventh aspect of the present invention is the ship according to any one of the first to fifth aspects, wherein the ship continues upward from the hull outer plate and is in the bow-stern direction with respect to the upper structure side wall. A bulwark provided on the bow side of the upper structure, and the interposition part may be provided at an end of the bow side of the upper structure side wall.

  According to such a configuration, since the bulwark and the upper structure side wall are separated from each other, it is possible to suppress the stress between the upper structure side wall and the interposition part from affecting the bulwark. In addition, since the interposition part is provided at the end of the bow side of the upper structure side wall, it can be arranged independently of the bulwark and the interposition part, and the connection part between the upper structure side wall and the interposition part Space becomes easier to secure.

  Further, the ship according to the eighth aspect of the present invention is the surface according to any one of the sixth and seventh aspects, wherein the interposition portion faces upward of the bulwark when viewed from the ship width direction. It may be arranged below.

  According to such a configuration, when the main hull is viewed from the outside, it is possible to prevent the intervening portion from being seen by the bulwark. Therefore, it can prevent that an interposition part affects the external appearance of a ship.

  According to the present invention, weldability can be improved.

  According to the ship 1 of the first embodiment as described above, an angle larger than an angle formed by a surface facing the bow side of the upper structure front wall 22 and a surface facing the inner side in the ship width direction of the upper structure side wall 21. The first interposition wall 51 is connected to the upper structure side wall 21 so as to form the following. By having such a first interposition wall 51, a narrow space is formed even if the upper structure side wall 21 and the upper structure front wall 22 are arranged so that the angle between them is an acute angle. Can be reduced.

  For example, if a narrow portion where a space that can be welded by appropriately arranging a welding torch or the like cannot be secured is formed, it becomes difficult to ensure the soundness of the weld bead. Specifically, it becomes difficult to ensure reliable penetration and sufficient smoothness. As a result, the fatigue strength of the welded portion may not be ensured. In particular, the side wall 21 of the upper structure that is continuous with the hull outer plate 11 is greatly affected by the longitudinal bending of the main hull 10 with respect to the direction of the main hull 10 as the ship 1 sails. As a result, high stress is repeatedly generated between the upper structure side wall 21 and the upper structure front wall 22 which are structurally discontinuous.

Can do. Therefore, the stress level generated between the upper structure side wall 21 and the upper structure front wall 22 can be reduced.

  Further, the second interposed wall 52 is connected to the upper structure side wall 21 by the first interposed wall 51 and the third interposed wall 53. Therefore, the load acting in the direction pressed toward the upper structure side wall 21 is distributed to the first interposed wall 51 and the third interposed wall 53 via the second interposed wall 52. Therefore, deformation (for example, buckling) of the interposition part 5 can be suppressed. That is, the rigidity of the interposition part 5 can be further improved as compared with a structure in which the first interposition wall 51 and the second interposition wall 52 are simply connected.

  Moreover, the box-like structure closed between the 1st interposition wall 51, the 2nd interposition wall 52, the 3rd interposition wall 53, and the upper structure side wall 21 can be formed with the interposition top plate 54. FIG. Therefore, the rigidity as the interposition part 5 can be improved.

That is, the interposition part 5 is provided facing the connection part of the upper structure side wall 21 and the bulwark 30. Therefore, since the upper structure side wall 21 and the bulwark 30 are formed continuously, the space between the upper structure front wall 22 is narrower than the state where the bulwark 30 is not formed. However, the region where a narrow space is formed by the interposition part 5 can be reduced. Furthermore, the rigidity of the connection part between the upper structure side wall 21 and the bulwark 30 can be improved, and the stress level generated in the connection part between the upper structure side wall 21 and the bulwark 30 can be reduced.

  Moreover, when the interposition part 5 is seen from the ship width direction, it is arrange | positioned below rather than the surface which faces the upper direction of the bulwark 30. FIG. Therefore, the bulwark 30 can prevent the interposition part 5 from being seen when the main hull 10 is viewed from the outside. Therefore, it is possible to prevent the interposition part 5 from affecting the appearance of the ship 1.
