Technical Field:

[0001] The present invention relates to the field of polar ship design, and particularly to a ship soft toe and a polar ship thereof. Background Art:

There are many cross structures, and conventional style structures will cause many problems. While meeting the requirements of people going up and down the ladder, it is relatively difficult to meet the requirements of structural strength, stiffness, and fatigue.

[0003] Especially for polar ships, due to the particularity of their structures, higher requirements are imposed on the overall rigidity and strength, and the existing technologies are even less able to meet their requirements for rigidity and strength.

[0010] In one embodiment, an extended deck is arranged on the other side of the inner wall. Along the extended deck, one side edge of the extended deck abuts against the inner wall, and a first longitudinal side wall is arranged on the other side of the inner wall.

[0011] In one embodiment, the starting and ending points of the first longitudinal side wall on the horizontal plane form rounded corners in different directions, and the ending point is connected to the second longitudinal side wall on the other side.

[0012] In one embodiment, an L-shaped steel is arranged at the end of the escalator, and the two ends of the L-shaped steel are respectively fixed to the vertical supports on both sides of the escalator.

[0013] In one embodiment, the first end of the long side adopts an arc transition with a long hole structure, and the second end of the long side adopts arcs with different arc radii and is perpendicular to the bulkhead.

[0014] In one embodiment, the escalator is provided below the escalator hole, and an inclined ladder is provided above the escalator hole.

[0039] Reference is made herein to the various aspects and features of the present application with reference to the accompanying drawings.

[0040] These and other features of the present application will become apparent from the following description of the preferred forms of the embodiments given as non-limiting examples with reference to the accompanying drawings.

[0041] It should also be understood that although the present application has been described with reference to some specific examples, those skilled in the art can surely implement many other equivalent forms of the present application, which have the features as described in the claims and thus are all within the protection scope defined thereby.

[0042] When combined with the accompanying drawings, the above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description.

[0043] Hereinafter, specific embodiments of the present application will be described with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of the present application and can be implemented in various ways. Well-known and / or repetitive functions and structures are not described in detail to clarify the true intention based on the user's historical operations and to avoid unnecessary or redundant details from obscuring the present application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but are merely used as a basis for the claims and a representative basis for teaching those skilled in the art to use the present application in substantially any suitable detailed structure in a variety of ways.

[0044] This specification may use the phrase "in one embodiment", "in another embodiment", "in yet another embodiment" or "in other embodiments", which may each refer to one or more of the same or different embodiments according to the present application.

[0045] The object of the present invention is to solve the problem that there are contradictions among the gangway opening, structural strength, stiffness and welding, which cannot be satisfied simultaneously, and to achieve deformation and cutting during structural cutting and avoid fillet welds and butt welds, so as to reduce the difficulty and time cost of welding, grinding and painting for welders during shipbuilding and reduce the construction cost.

[0046] In the areas of flowing water holes and stairway holes, the structural forms are relatively complex and there are many cross structures. In this case, without affecting the ladder arrangement, the ladder holes can be made into irregular soft toes to achieve a certain distance from avoiding fillet welds and butt welds, and it can also improve the fatigue life of the structure, making it easier for welding, grinding and painting. During the structural cutting stage, it is not easy to have the situation of too thin edges being prone to deformation and breakage.

[0047] The above problems will seriously affect the stiffness of the overall ship, so new structures are needed to meet the strength and stiffness requirements of the new ship type.
