How to bend the deck end of a ship {Method for Knuckling Deck Edge for Ships}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of knuckleing the deck edge of a ship and is safe by eliminating narrow spaces such as decks and side shells or side shells and bulkheads generated from the bow and stern of the ship. The present invention relates to a method of bending a deck end of a ship for productivity and quality improvement by enabling work.

As long as the ship's bow or stern is highly linear and there are internal spaces such as decks and partitions at designated locations, narrow spaces occur, which can lead to reduced productivity and structural defects due to deterioration in traffic and problems in process performance. Can be.

1 is a plan view showing the deck end of the bow or stern side of the ship. As shown in the figure, the side shell 10 is inclined and the plurality of openings 30 are aligned side by side along the plurality of floors 20.

Conventionally, decks 40 (deck) are integrated into the same space, so it is not possible to use a place where a tight boundary is required, and the sewage flowing through the outer plate has to flow below deck 40, and the deck and Since the shell plates are not connected to each other, the rigidity is lowered and the deformation of the two members is increased. In all frames the brackets form hot points on the shell plate, ie points with out-of-plane thicknesses, so brackets are essential and in order to place the openings of the deck ends in one plate. Additional slope seam is needed.

FIG. 2 is a cross sectional view viewed from the deck lower stern towards the bow, with the same or similar reference numerals being assigned to the same or similar parts as FIG. In the figure, 40 is a deck and 50 is a web frame. In addition, 60 is a color plate (collar plate), and it is necessary to reinforce when it exceeds a predetermined length. In addition, 70 is a bracket. 80 is Shell Longi. (Longitudinal). Opening the deck as shown in Figure 1, as shown by ① in the drawing, the accessibility of the side shell 10 side is secured, but as shown in ②, the deck 40 lower portion is not secured time and workability is reduced. Since the deck is open, the floor end forms a hot point on the shell plate, and the bracket is necessary to avoid damage to the shell plate. In the past, there have been cases where the brackets were delivered and followed up. In the drawing, the work load increases because all frames of section 3 must be transversely stiffened in the ship, but the longitudinal rigidity is weak, and the scallops installed on web frames and brackets are long. Color plate 60 is required because it exceeds a predetermined length, and as shown in the floor plate 20 shown in FIG. 2, the shape of the floor plate 20 is too sharp so that it is easily deformed or damaged during transportation and assembly. There was. Deep deck openings reduce the cross-sectional coefficients, making the web frame impossible.

The present invention is to solve this problem, the method of bending the deck end of the ship to be able to improve the productivity and quality to reduce the narrow space by bending the deck end of the ship, to enable safety work The purpose is to provide.

In addition, another object of the present invention is that the linear change in the bow and stern of the ship is severe, so that the deck and partition at the designated position also equally solve the narrow space to perform the safety work, and contribute to the productivity improvement.

According to one aspect of the present invention for achieving the above object, the present invention is a side shell and deck or side shell and partition of a ship comprising a side shell, deck, Shell Longi. In the method for eliminating the same narrow space,
And bending the deck end of the ship by stiffening the side shell and the deck in the transverse direction of the ship.

According to the present invention, by bending the end of the deck of the ship, the narrow space is fundamentally eliminated and is accessible everywhere in all processes, the bent member serves as a girder and connect the floors to the end rigidity As it increases, it is advantageous to prevent deformation, and if the shell longage adjacent to the upper and lower parts is properly relocated based on the bent member, a large number of brackets on the upper and lower parts can be deleted, resulting in a simple but sturdy structure and reducing the amount of work. It is easy to produce and safe work can be achieved.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The same or similar reference numerals are given to parts of the same similarity throughout the drawings.

3 shows a top view of a deck end in accordance with an embodiment of the present invention. As shown in the figure, the bending member 90 is provided in parallel with the side shell 10. If there is coaming, there should be no scallop 100 in the web frame.

Since the end of the deck is bent in order to eliminate the narrow space at the source, the deck 40 can be selectively integrated with the upper and lower spaces or used as a seamless boundary. The sewage flowing through the outer plate can be flowed down or blocked under the deck, and the deck edge bending part can act as a girder, which increases the rigidity and contributes to the prevention of deformation. Can be solved. Block joints (not shown) located on the upper deck in parallel with the deck 40 can be moved to the side of the bending member, eliminating the need to install the color plate 60, and shell longage (shown with reference to the bending member 90). It is necessary to secure additional workability by adjusting the space.

4 is a transverse cross-sectional view from the stern of the deck edge toward the bow, according to one embodiment of the invention. By bending the end of the deck, the narrow space is essentially eliminated and accessible in all processes. In the drawing, the length l is within a predetermined length, unlike the prior art, so that the color plate (Fig. 2) is not necessary.

In the drawing, the triangle representation is a block butt, that is, a block and a boundary point of the block. If necessary, make a scallop 100 which is a semicircular hole. Since the bent member connects the girder role and the floors to increase the end stiffness, it is advantageous in preventing deformation. By properly rearranging the shell longage 80 adjacent to the upper and lower parts on the basis of the bent member, a large number of brackets of the upper and lower parts may be deleted, resulting in a simple but robust structure and reducing the amount of work. In addition, when the sewage flowing through the outer shell flows downward, scallops are installed at both ends and the lowest part of the bent member. Difficulty of design increases, but narrow space is solved and workability is excellent, so production is easy and safety work is possible.

5 is a view showing the construction criteria of the deck end portion, it is determined whether the knuckle according to the angle θ between the deck 40 and the side shell 10.

In FIG. 5, that is, when the side shell inclination is 25 degrees or less at the point of 1000 mm from the end of the deck when? The vertical distance between the deck and the side shell is 500mm. As shown in the figure, bending is performed even when θ is 20 degrees. As shown in FIG. 5, the bending is not performed when θ 25 degrees or more, which was determined experimentally.

6 is a view showing in more detail the construction criteria of the deck end portion.

As shown in the figure, a drain scallop 100 is provided if necessary. 5, that is, when θ ≦ 25 °, the deck is bent at an angle of 75 ° at a point about 500 mm apart to the side shell 10. As shown in the figure, the distance between the deck 40 and protrusions such as the shell longage 80 is to be at least 400 ~ 500mm. If necessary, a coaming is provided and a drain scallop 100 is provided. If the bend is at the tank boundary, scallops and coaming are not necessary. Instead, the department is notified and boundaries are reflected in the expansion and marking drawings. In the case where the bent area is vertically integrated, scallops are installed at both ends and the lower part of the knuckle member so that sewage from the shell flows and coaming is provided at the end of the deck.

One embodiment of the present invention has been described above with reference to the drawings, but the present invention is not limited thereto, and various modifications and variations are made by those skilled in the art without departing from the spirit and scope of the appended claims below. It is to be understood that such modifications and variations are intended to be within the scope of the present invention.

For example, the present invention has been described mainly to solve the narrow space of the side shell and the end of the deck, it can be applied to the elimination of the narrow space such as the side shell and partition.
