Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of securing a plurality of containers stacked on a deck of a ship.

[0002]

2. Description of the Related Art It has been customary to stack a large number of containers in multiple stages and transport them by ship.

In transporting containers such as those mentioned above,
Many containers are stacked in the hold and on the deck.
Containers stacked in the hold are supported by cell guides, so they have good stability and do not require lashing.

On the other hand, in the containers stacked on the deck, the stacked containers are tilted due to the left and right shaking of the hull, and the tilt changes the position where the upper container pushes down the lower container, and the lower container moves. If the container is deformed into a rhombus and is greatly deformed, the container may be damaged.

The deformation of the container into a rhombus is called racking, and in order to prevent the racking, the containers stacked on the deck are normally stabilized by lashing.

[0006] FIG. 12 shows an example of lashing of containers stacked on the deck 2. In this example, between the corner metal fittings A provided at the upper four corners of the bottommost container C ₁₁ stacked on the deck 2 and the deck 2, the expansion and contraction-adjustable binding tool 10 is attached to the end surface of the container C ₁₁ . The two lashing tools 10 arranged on the side are slantingly crossed so that a part of the lashing tools 10 cross each other, and the fastening of each lashing tool 10 stabilizes the lowermost container C ₁₁ .

[0007] Further, a securing device 10 which is adjustable in expansion and contraction is arranged on the end face side of the container between the corner fittings A provided at the lower four corners of the container C _{12 of} the next stage and the container C ₁₃ of the uppermost stage and the deck 2. A part of the lashing tool 10 to be crossed is obliquely crossed over, and each lashing tool 10 is tightened to stabilize the next-stage container C ₁₂ and the uppermost container C ₁₃ .

Here, as the fastening tool 10, FIG.
As shown in (I) and (II), each container C ₁₁ , C ₁₂ ,
A lashing rod 1 having at one end an engaging head 12 capable of engaging with an engaging hole formed in a C ₁₃ corner fitting A.
1 and a turnbuckle 13 having one end connected to the other end of the lashing rod 11 and the other end detachably connected to a connecting fitting provided on the deck 2.

[0009] In recent years, for the purpose of reducing the transportation cost of containers, it is becoming more common to transport the containers by stacking them in four or more stages on the deck. At this time, the height of one container is 8 feet (2438 mm) or more, and if the containers are stacked in four or more steps, the uppermost container becomes extremely tall, and the uppermost container cannot be secured. It will be extremely difficult.

Therefore, as shown in FIG. 13, in a container transport ship that transports containers stacked in four or more stages, a lashing bridge 3 extending on the deck 2 in the port side direction of the hull is extended from the length of the container in the longitudinal direction of the hull. Containers C ₁₁ , C ₁₂ , C ₁₃ , C ₁₄ are stacked between the lashing bridges 3 at long intervals, and the containers C ₁₂ , C positioned above the upper surface of the lashing bridge 3 are stacked.
The fastening tool 10 is slanted across the corner fitting A of ₁₃ and C ₁₄ and the upper part of the lashing bridge 3, and each container C ₁₂ , C ₁₃ and C ₁₄ is stabilized by tightening the fastening tool 10. ing.

[0011]

By the way, in the lashing of the container shown in FIGS. 12 and 13, by tightening the lashing tool 10 extending in the diagonal direction, the corner metal fitting A is pulled in the diagonal direction, and the container C ₁₁ In order to stabilize C to C _14, the horizontal tensile load applied to the corner fitting A is small, and the lateral movement of the containers C _{11 to} C _{14 in} each stage cannot be effectively prevented. for that reason,
The lower stage container, which is the base, has low supporting rigidity, and the uppermost containers C ₁₃ and C ₁₄ also need to be secured by the securing tool 10.

In this case, the lashing rod 11 of the lashing tool 10 for lashing the uppermost containers C ₁₃ and C ₁₄ needs to be long and have a large diameter and a large tensile load. For this reason, the workability is extremely poor, it takes a long time for lashing, and the operator is also fatigued.

If the turnbuckles 13 used for securing the containers C _{11 to} C _{14 at} the respective stages have different tightening lengths, the turns suitable for securing the containers C _{11 to} C _{14 at} the respective stages. Since it becomes necessary to select and use the buckle, the workability of securing the containers C _{11 to} C _{14 in} each stage is significantly reduced. Therefore, conventionally, the same type of turnbuckle 13 is used to perform lashing.

In this case, as the turnbuckle 13,
A turnbuckle 13 having a long tightening length and a heavy weight that enables the uppermost containers C ₁₃ and C ₁₄ to be secured is required. For this reason, the workability of tightening and loosening is poor, and it takes time to tie the containers C _{11 to} C ₁₄ at each stage, and the ship staying time becomes long.

An object of the present invention is to provide a container lashing method capable of shortening the container lashing operation time and reducing operator fatigue.

[0016]

In order to solve the above problems, in the first aspect of the present invention, lashing bridges extending long in the port side direction of the hull are provided on the deck of the hull at intervals in the longitudinal direction of the hull. , A plurality of containers are stacked on the deck between the front and rear lashing bridges in a multi-tiered manner so that the length direction thereof is in the front-back direction of the hull, and the lower surface is held at substantially the same level as the upper surface of the lashing bridge.

It is possible to obtain a stable supporting state with extremely high supporting rigidity. As a result, it is possible to eliminate the need for lashing for the uppermost container, eliminating the need for long and heavy lashing rods and turnbuckles with a large amount of tightening, which were required in the past, and improving the workability of lashing. As a result, the lashing time can be significantly shortened and the fatigue of the operator can be reduced.

[0019] Here, a lashing tool that is adjustable in expansion and contraction is arranged on one side of the container between each corner metal fitting on the upper ends of the container and the upper part of the lashing bridge where the lower corner metal fitting is substantially horizontal lashing.

As shown in FIG. 1, a plurality of lashing bridges 3 extending in the lateral direction of the hull 1 are provided on a deck 2 of the hull 1 at intervals in the front-rear direction of the hull 1. The distance between the front and rear lashing bridges 3 is large enough to accommodate the container in the longitudinal direction. Further, the height of the lashing bridge 3 is set to be an integer multiple of the height of a commonly used container. As shown in FIG. 2, in the embodiment, the height of the lashing bridge 3 is substantially equal to the height of the container.

As shown in FIG. 2, the first container C _{1 to} the fourth container C ₄ are stacked on the deck 2 between the front and rear lashing bridges 3, and the stacked containers are the lengths of the lashing bridges 3. It is provided in multiple rows in the direction.
