Abstract

PURPOSE:To increase container stowage load to the hull, by dispersing load on a topmost stage container in a broadside container train via a short beam. CONSTITUTION:A short beam 1 is engaged and connected to a strut 5 pivotally supported on a hull structure, and engaged to a container train in an inside part adjacent to a broadside part container train with a stacking cone 16a of a stacker 7. At the broadside container train side of the stacker 7, the stacking cone on the bottom surface is engaged with a topmost stage container, and the top stacking cone 16a is fitted in a fitting hole. At the inside part container train side adjoining to the broadside container train, each of these upper and lower stacking cones is engaged with the topmost stage container and the lower container, respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container stowage method on a discharge ship, which appropriately disperses the load 1 at the top of the container caused by the ship's shaking during container stowage without using a cell guide, and reduces the stowage load of the container. It is intended to increase the size of the .

Industrial applications Container stowage technology on bulk carriers.

BACKGROUND OF THE INVENTION The use of structurally supported struts for loading containers on bulk carriers is conventional.

That is, when loading busy containers such as in the hold of a bulk carrier, since the hinge 21 of the hatch cover 20 protrudes downward as shown in FIG. The topmost container (phantom) is often unable to be loaded, and in such cases, the load of the containers in each row of containers pushed into the hold acts on the container (A) located below the container (B) above. , #container (A) is transmitted through the strut 5.

In addition, when the above container (B) is stacked on top of the container (A), the load caused by the oscillation is absorbed by the container (
It is held so that it is received by the top of container (A) and the bottom of container (B). Furthermore, it is clear that the load is generally applied to the bottom of a container rather than the top, and it is well known that the strength of the bottom is greater.

Problems to be Solved by the Invention However, in the conventional system as described above, when the container (11) is not present, the load of the full stop container (B) is reduced compared to when the container (B) is present. There is a disadvantage, that is, the permissible load at the bottom of the container (B) mentioned above is
B, and if the allowable load at the top of container (A) is taken as the back, then when container (B) is loaded, strut 0 will be able to transmit a load equivalent to the total of these loads, whereas when container B is not loaded, In some cases, only that WT is available, so the number has to be reduced.For example, Lloyd's Register (LR8) uses the WT-22,5t.

Since the weight is WB-35t, the cargo load will inevitably be significantly reduced.

Structure of the Invention Means for Solving the Problems The present invention was devised in 5&C to solve the above-mentioned problems of the conventional type. Equipped with a single short beam used between adjacent inner container rows,
A method for stowing containers on a bulk ship, characterized in that the short beam is moored and coupled between the strut engaged with the upper surface of the uppermost container in the side container row and the upper part of the inner container row. .

The load on the nine uppermost containers in the side container row, which occurs when the ship is rocking, is dispersed through the short beam.

Therefore, the container stowage load on the bulk ship is not limited to the permissible load of the uppermost container in the side container row, increasing the container stowage load on the ship.

Example 1
'The embodiment of the present invention as described above will be explained with reference to the attached drawings.In the present invention, the short beam 1 as shown in detail in Figs. 2 and 3 is used in the case described above. There are many attempts to solve this problem and also to obtain advantageous stowage in other cases.

That is, in the present invention, a short beam 1 having a strength corresponding to the allowable load WB at the bottom L&C of the container (B) during loading as shown in FIG. 1 is used, and the short beam 1 is attached to the strut 5. An example of a specific structure of such a short beam 1 is shown in FIG. 2.3. That is, the beam 1 is provided with a fitting hole 16 so that one end thereof is attached and engaged with the stacking cone 6 portion of the strut 5, and consists of beam parts 2 on both sides integrally connected by a connecting part 3. A bent part 12 is formed in the middle part of the beam 1 to provide a cushioning effect against compression and tension. A fitting hole 6a is formed to engage with a stacking cone 16m of a stacker T interposed between the abutted corners of the upper container in the inner container row adjacent to the container row and the upper container in the side container row. . Beam 1! /c has a suspension part 9 formed thereon so that it can be handled and operated by a crane, etc. For details of the part where the fitting holes 6, 6a for the stacking cones 16, 1eaK as described above are formed, Second
As shown in the figure, it is provided on the bottom surface of an end socket 8 attached to both ends of the short beam 1.

The specific structure of the strut 5 is as shown in FIG. 4, in which the guide portion 5c and the stacking cord/1
A stacker portion 5d having stacker portions 6 arranged vertically opposite each other is provided in a protruding manner, and a pin 5, which is attached to an eye grating 4 or the like of the hull structure, is inserted into the clevis portion 5aK.

One of the specific embodiments of the method of the present invention using the short beam 1 according to the present invention as described above is as shown in No. In the row group, the uppermost part of the row of containers on the side of the ship is in a state where there is one less container than the row of containers on the inner side due to the hatch cover hinge section as described above, and such container rows on the side A front station short beam 1 is attached to the top of the top container (B) in the row, and such a short beam 1 is attached to the strut 5 which is supported by the hull structure.
The stacking cone 16 & of the stacker 1 as described above is engaged with the container row on the inner side which is set back from the container row on the side. On the side container row side of the stacker T, the bottom stacking cone engages with the uppermost container (B), and the upper stacking cone 1Bm is fitted into the fitting hole 6aK, but the adjacent inner container row As shown in the figure, the upper and lower stacking cones of the side are engaged with the uppermost container and the lower container, respectively. That is, by stacking containers in this manner, the load is effectively transmitted through the short beam 1, and the overall container cargo load is not reduced.

As shown in Fig. 5, even when the top tier is loaded with the same load on the side as on the inside, the above-mentioned short beam 1 can be used to transfer the load caused by the ship's oscillation to the top of the top container in the row of side containers. By increasing the load when loading containers, it is possible to obtain the same effect as when the strength of the top of the topmost container in the row of side containers is significantly reinforced.
Furthermore, short beam 1 is placed in the 5-side container row as shown above! ! It is possible to connect not only the rows of containers that are in contact with each other, but also the rows 2 and 3 that are adjacent to each other, and thereby increase the allowable load of the containers from 1* to 0. Yuh b= v *U.
1 "Effects of the Invention" According to the present invention as explained above, the load on the top of the container that occurs when the ship sways can be appropriately distributed, and the load carried inside the container can be effectively increased, This invention has a great effect on container stowage on cargo ships.
