Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cell guide for a container ship.
[0002]
[Prior art]
When loading and unloading containers, cell guides are stood in the container ship's hold and are guided by guiding the four corners of the containers along the cell guides so that blocks are stacked.
[0003]
FIG. 5 is a container ship, (A) is a side view of the container ship, and (B) is a cross-sectional view.
In the figure, 1 is a container ship. The size of the container ship 1 is generally designed with a ship width of 32.2 m or less so that the Panama Canal can pass through (Panamax type). Recently, an overpanamax type large container ship with a width of 32.2m or more has been built. Reference numeral 2 denotes a container stored in the hold of the container ship 1 and on the upper deck. The dimensions of the container 2 are standardized by international standards, but those having a length of 20 feet and 40 feet are mainly used. The container 2 in the hold is guided and stored by a cell guide described later, and the container 2 on the upper deck is fixed to the container ship 1 by a lashing device (not shown). In general, in the case of a container ship having a ship width of 32.2 m, 10 containers are stored in the ship width direction.
[0004]
FIG. 6 is a perspective view showing a conventional cell guide and a container. FIG. 7 is a partially enlarged view of FIG. FIG. 8 is a front view of the entry guide.
In the figure, reference numeral 3 denotes a cell guide, which uses an angle steel 3a. 3b is a flange of the angle steel 3a. The cell guide 3 is erected vertically in the hold of the container ship 1, and an entry guide 3A is provided at the upper end thereof as shown in FIG. The entry guide 3A smoothly guides the four corners of the container 2 to the angle steel 3a of the cell guide 3 when the container 2 is suspended in the hold. The container 2 is guided along the cell guide 3 and stored so as to overlap blocks. Reference numeral 4 denotes a horizontal rib having a projection 4a at the center, which is fitted between both flanges 3b of the adjacent angle steel 3a of the cell guide 3 and welded to the outer surface of the angle steel 3a on the back side. A plurality of horizontal ribs 4 are welded at predetermined intervals in the vertical direction on the back side of the angle steel 3 a of the cell guide 3, and the horizontal ribs 4 from the container 2 generated due to the lifting and lowering of the container 2 and the hull motion of the container ship 1 are It is a reinforcing material that prevents the flange 3b of the angle steel 3a from being deformed by a load.
[0005]
FIG. 9 is a diagram showing the distance between the cell guides.
In the figure, A is an interval between containers 2 which are guided and stored by the cell guide 3. When the container 2 is brought close to the cell guide 3, gaps s 1 and s 2 of about 10 mm are usually provided between the container 2 and the cell guide 3. B is the internal dimension of the flanges 3b of the adjacent angle steels 3a of the cell guide 3. As the cell guide 3, for example, an angle steel 3a having a cross-sectional dimension C × D = 150 × 150 mm of JIS standard and t = 12 mm is used. Usually, from a welding work or a painting work for attaching a horizontal rib, At least B dimension is about 70 mm. Reference numeral 6 denotes a connecting material in which the flanges 3b of the angle steel 3a are connected to each other.
[0006]
[Problems to be solved by the invention]
In the case of the above-mentioned Panamax type container ship, it has been the maximum to store 10 containers in the width direction of the ship so far, but recently there has been a demand for storing 11 containers. However, in order to store 11 containers in the Panamax type container ship, the space between the ship side skin and the inner wall must be narrowed, and the space between the containers to be loaded must be narrowed. Narrowing the gap between the two is difficult in terms of strength design, and in order to narrow the gap between the containers to be loaded, it is difficult to narrow the cell guides because of welding work or painting work.
[0007]
The present invention was devised in order to solve the above-described problems, and by narrowing the space between the angle steels of the cell guide and accommodating containers as close as possible to each other, the ship side skin plate and It is an object of the present invention to provide a cell guide for a container ship that can facilitate the strength design of the container ship by widening the distance from the inner wall.
[0008]
[Means for Solving the Problems]
According to the present invention, a flat steel having a width shorter than the width of the flange is sandwiched and welded in the longitudinal direction between the outer surfaces of adjacent flanges of two angle steels constituting the cell guide, There is provided a cell guide for a container ship in which a groove portion is formed on the back side of the steel plate, and a projection of a horizontal rib having a projection at the center is fitted into the groove portion and welded to the outer back surface of the angle steel.
[0009]
The width of the flat steel is larger than the width of the flange of the angle steel, a part of the flat steel protrudes from the back of the angle steel, and a recess that fits into the protrusion of the flat steel is formed at the center of the horizontal rib. You may have.
[0010]
The flat steel has the same width as the flange of the angle steel, and the back side of the angle steel and the end surface of the flat steel may be welded flush with each other.
[0011]
It is preferable to have an appropriately shaped aperture in the middle of the flat steel.
[0012]
Next, the operation of the present invention will be described.
Since the two angle steels constituting the cell guide are firmly welded with the flat steel sandwiched therebetween, sufficient strength can be obtained even if the angle between the angle steels is narrow, and the gap is sealed. Therefore, it does not rust and no painting in the gap is necessary.
[0013]
[Embodiments of the Invention]
Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a partial perspective view of a cell guide for a container ship according to the first aspect of the present invention. The same parts as those shown in FIG. 4 to FIG. 6 are described with the same reference numerals, and redundant description is omitted.
[0014]
In the figure, 3 is a cell guide, 3a is an angle steel constituting the cell guide 3, 3b is a flange of the angle steel 3, 4A is a horizontal rib, and 4b is a protrusion provided at the center of the horizontal rib 4A. 5 is a flat steel. Reference numeral 7 denotes a welded portion where the flat steel 5 and the flange 3b are welded. Reference numeral 9 denotes a groove provided on the back side of the angle steel 3.
[0015]
The cell guide 3 sandwiches a flat steel 5 having a width shorter than the width of the flange 3b over the entire length in the longitudinal direction between the outer surfaces of the adjacent flanges 3b of the two angle steels 3a constituting the cell guide 3. And forming the groove 9 on the back side of the angle steel 3a, and fitting the protrusion 4b of the horizontal rib 4A having the protrusion 4b in the center to the groove 9 to weld the back side outer surface of the angle steel 3a, A plurality of the horizontal ribs 4A are welded at predetermined intervals in the vertical direction of the two angle steels 3a.
[0016]
FIG. 2 is a partial perspective view of a cell guide for a container ship according to a second aspect of the present invention. The same parts as those shown in FIG. 1 will be described with the same reference numerals.
1 is smaller than the width of both flanges 3b of the cell guide 3, whereas the flat bar 5A is larger than the width of both flanges 3b, and a part of the flat bar 5A is on the back side of the angle steel 3a. It protrudes. In addition, the horizontal rib 4A in FIG. 1 has a protrusion 4b in the center, whereas the center of the horizontal rib 4B has a recess 4c that fits into the protruding portion 5a of the flat steel 5A.
[0017]
FIG. 3 is a partial perspective view of a cell guide for a container ship according to a third aspect of the present invention.
The width of the flat steel 5B is the same as the width of the angle steel 3a, the back side of the angle steel 3a and the end surface of the flat steel 5B are welded flush with each other, and the horizontal rib 4C has neither protrusions nor recesses. . 8 is a groove for welding, and 7 is a welded portion (one-dot chain line).
[0018]
FIG. 4 is a partial perspective view of a flat steel.
If an appropriately shaped opening 5a as shown in the figure is provided in the middle of the flat steels 5, 5A, 5B, the weight of the flat steels 5, 5A, 5B can be reduced.
[0019]
Next, the operation of this embodiment will be described.
Since the two angle steels 3a constituting the cell guide 3 are firmly welded with the flat steel 5 interposed therebetween, sufficient strength can be obtained even if the interval between the angle steels 3a is narrow, and there is no gap. Since it is sealed, it does not rust and does not require painting in the gap. The effect of the present invention will be specifically described. As described with reference to FIG. 9, the angle steel of C × D × t = 150 × 150 × 12 mm used in a normal container ship is designed to satisfy s1 = s2 = 10 mm. Further, a gap of at least B = 70 mm is provided between the flanges 3b of the angle steel 3a. For example, if a flat steel 5 having a thickness of 25 mm is used, the gap is only 25 mm and can be reduced by 45 mm. Therefore, if 11 rows of containers are loaded, the gap of 45 mm × 10 = 450 mm can be reduced in all cell guides. Accordingly, the distance between the outer surfaces of the outermost cell guides (ie, closest to the inner wall on the ship side) is at least 450 mm shorter, so that the inner wall can be moved inward by a half (225 mm) dimension, Since the distance from the inner wall can be increased, the strength design is facilitated.
[0020]
The present invention is not limited to the above-described embodiment, and various changes can be made without departing from the scope of the present invention. For example, a groove portion may be provided on each of the back side of the angle iron and the front end side of the flange, or a groove portion may be provided on one of them, and a protrusion may be provided on the other side.
[0021]
【The invention's effect】
As described above, according to the present invention, since the space between the angle steels of the cell guide is narrowed, the containers can be accommodated close to each other, and accordingly, the space between the ship side skin and the inner wall can be increased accordingly. It has excellent effects such as widening and making it easy to design the strength of container ships.
