Abstract

PROBLEM TO BE SOLVED: To provide a loading structure of a long container in a container ship to enable many long containers to be loaded without overlapping with short containers. SOLUTION: Intervals between opposing support plates 21 which sandwich hatches 12 of lashing bridges 20 are set so as to be able to support both ends of a 45ft container 33 in the longitudinal direction. Further, support seats 22 are provided at predetermined intervals widthwise of the ship so as to correspond to the both side end portions of the 45ft container. The structure is such that the 45ft container 33 is able to be loaded between the lashing bridges 20, supporting at its four corners by the support seats 22.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for loading containers on an upper deck of a container ship, and more particularly to a structure for loading long containers.

[0002]

2. Description of the Related Art A container ship has an opening (hatch 12) formed in an upper deck 11 as shown in FIG.
The container 30 is housed in the hold 1A via the
The hatch 12 is closed by a hatch cover 14 and a plurality of layers are stacked to mount a container 30.

A hatch combing 13 having a predetermined height is provided upright at an opening edge of the hatch 12.
Is placed on the hatch combing 13.

[0004] The hatch 12 is set to have an opening length that allows a 40 ft container to be inserted into the hold 1A.
A lashing bridge 20 is provided upright on each of the front and rear sides of 2.

The lashing bridge 20 has a height substantially equal to that of the container 30, and a container mounted on the hatch cover 14 is secured to the lashing bridge 20 by a container securing hardware.

The container 30 has four lower corners engaged with a container receiving member 14A provided on the upper surface of the hatch cover 14, so that one 40 ft container 31 and two 20 ft containers 32 are stacked in series. ing.

[0007] In recent years, the circulation volume of long containers of 40 ft or more, such as 45 ft containers, has been increasing. When such a long container is to be loaded on a container ship in which containers are stacked on the hatch cover 14 between the lashing bridges 20 as described above, the upper surface of the long container is separated from the lashing bridge 20 in order to avoid interference with the lashing bridge 20. 40 ft or 20 ft containers 31 and 32 are stacked in two layers so as to be higher, and a long container 33 is stacked thereon.

[0008]

However, in the above-mentioned conventional configuration, 40 ft is stored in a container loaded on the upper deck.
Alternatively, there is a problem that long containers cannot be loaded unless the number of 20 ft containers is a predetermined number.

Also, since 40 ft or 20 ft containers are stacked so that the upper surface is higher than the lashing bridge and long containers are loaded thereon, a large number of 40 ft or 20 ft containers are required, and The loading ratio of the long container to the container was small.

The present invention has been made in view of the above problems, and provides a structure for loading a long container in a container ship capable of loading more long containers without overlapping the short container. With the goal.

[0011]

According to the present invention, there is provided a container ship having a long container loading structure in which a lashing bridge extending in the width direction of a ship is provided on an upper deck with a hatch opening therebetween. The short containers are stacked on the hatch cover arranged so as to close the hatch opening, and the long containers are supported on the lashing bridge at both ends in the longitudinal direction. It is characterized by being constituted so that.

[0012]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a partial side view of a container ship to which a configuration example of a long container loading structure in a container ship according to the present invention is applied, and FIG. 3 is a sectional view taken along line BB of FIG.

In the illustrated container ship, a hatch 12 of a predetermined length capable of inserting a 40 ft container into a hold is arranged in the ship length direction, and a lashing bridge 20 extending in the ship width direction is provided between the hatches 12. Have been.

An opening edge of the hatch 12 is bordered by a hatch combing 13 erected on the upper deck 11, and a lashing bridge 20 is erected on the hatch combing 13.

The hatch 12 is closed by a hatch cover 14 placed on the upper edge of the hatch combing 13.
On this hatch cover 14, one 40 ft container 31 or two 20 ft containers 32 can be stacked in series, and if all the loading containers are 40 ft containers 31 or 20 ft containers 32, a predetermined They are stacked in layers.

The lashing bridge 20 has support plates 21 erected on both front and rear sides thereof.
2, and an eye plate 23 for securing containers is provided at a predetermined position.

The distance between the support plates 21 facing each other across the hatch 12 of the lashing bridge 20 is set so as to support both longitudinal ends of a long container (45 ft container 33 in the present configuration example). The support seat 22 is 45
The ft containers 33 are provided at predetermined intervals in the boat width direction so as to correspond to both end portions. Thereby, the 45 ft container 33 can be loaded between the lashing bridges 20 with its four corners supported by the support seats 22.

The height of the support seat 22 is set to be higher than the upper surfaces of the containers 31 and 32 loaded on the hatch cover 14 by a predetermined amount. There is a predetermined gap between the lower surface 32 and the lower surface of the container 33 loaded on the lashing bridge 20.

In the container ship constructed as described above, the containers 31 and 32 of 20 ft or 40 ft are loaded on the hatch cover 14 covering the opening of the hatch 12, and the containers 31 and 32 are loaded on the hatch cover 14. The 45 ft container 33, which is a long container that cannot be used, is loaded on the lashing bridge 20.

That is, the containers 31 and 32 of 20 ft or 40 ft are stacked on the hatch cover 14, while the long 45 ft container is stacked on the containers 31 and 32 stacked on the hatch cover. Instead, the container is loaded while being supported by the lashing bridge 20, so that a long container can be loaded even if there is no 40ft or 20ft container in the container loaded on the upper deck. Yes, and 20 ft
Alternatively, since 45 ft containers can be loaded without stacking the 40 ft containers 31 and 32 in two stages, more long containers can be loaded with respect to the total number of loaded containers.

In the above configuration example, four lashing bridges are used.
Although the configuration is such that a 5 ft container is loaded, the container is not limited to this, and a container of another size may be loaded on the lashing bridge.

[0023]

As described above, according to the structure for loading a long container in a container ship according to the present invention, a lashing bridge extending in the width direction of the ship is provided on the upper deck with the hatch opening therebetween. Provided at intervals corresponding to
The short containers are stacked on the hatch cover arranged to close the hatch opening, and the long containers are supported and loaded on the lashing bridge at both ends in the longitudinal direction. A short container can be loaded on the hatch cover covering the opening of the hatch, and a long container that cannot be loaded on the hatch cover can be loaded on the lashing bridge.

That is, there is no need to stack short containers on the hatch cover higher than the lashing bridge and to stack long containers on top of each other, so that a predetermined number of short containers are not loaded on the upper deck. However, it becomes possible to load long containers and also to load more long containers with respect to the total number of containers.
