Description

[Detailed description of the invention] This invention relates to the mounting structure for container lashing hardware, and is applicable to decks and double decks of roll-on/roll-off ships, multi-purpose ships, general cargo ships, etc. that do not have cell guides capable of loading containers. This invention relates to a mounting structure for container securing hardware installed on a bottom plate, etc. (hereinafter simply referred to as deck).

Conventionally, in order to attach container lashing hardware to the double bottom plate of roll-on/roll-off ships, multipurpose cargo ships, etc.,
Usually, as shown in Fig. 1, a notch for fitting the container lashing hardware is provided on the upper part of the girder 1 or the horizontal member, and the container lashing hardware 2 is placed on the notch of the reinforcing member 1 and fixed by welding. In addition, the upper circumferential surface of the container lashing hardware and the double bottom plate 3
The inner surface of the opening 3' is welded and fixed so that the top surface of the container lashing hardware and the top surface of the double bottom plate are on the same bottom surface, and the collar plate 4 of the container lashing hardware 2 is fixed for reinforcement.
is connected to a longitudinal frame 6 or a beam via a bracket 5.

7 is a container cone hole provided in the container lashing hardware 2.

The mounting structure of such a container lashing hardware is almost the same when the container lashing hardware is attached to a deck or the like.

However, in the case of this prior art, the following problems have occurred due to its mounting structure.

■ Container lashing hardware is restricted by the arrangement of horizontal members or stringers, making it impossible to secure an efficient loading position for containers.

On the other hand, if priority is given to container placement, it is necessary to add girders or horizontal members, which increases both weight and man-hours.

■ Container lashing hardware is attached to the beam or longitudinal frame via brackets, which complicates assembly, increases man-hours, and poses problems in weldability.

■ Part of the girder and horizontal members are cut out for container lashing hardware, resulting in insufficient longitudinal and lateral strength of the ship.

The present invention was devised in view of the various shortcomings of the prior art, and its purpose is to provide a container lashing hardware that has a simple structure, is inexpensive, is easy to install, and is capable of efficiently arranging containers. The purpose is to provide a mounting structure.

The present invention will be described in detail below with reference to FIGS. 2 to 5.

In the figure, 10 is a stringer consisting of a longitudinal frame or a girder arranged at predetermined intervals in the hull length direction, 11 is a horizontal member arranged at predetermined intervals in the hull width direction, and 12 is a deck. , 13 is an opening for burying hardware for lashing the container, which is bored at a predetermined intermediate position of the longitudinal member 10 of the deck 12 in a non-connected manner in each of the longitudinal members 10 and the transverse members 11, and 14 is the opening. This is a container lashing hardware that is welded and fixed to part 13 so that the upper surface of the hardware is flush with the deck surface.

Reference numeral 15 denotes a curling material 15 for reinforcing the deck surface, which is provided on the lower surface of the deck before and after each container lashing hardware 14 so as not to interfere with each container lashing hardware and parallel to the horizontal member 11. The deck plate near the container lashing hardware is supplemented by welding and fixing the upper surface and both end surfaces to the lower surface of the deck 12 and the side surface of the stringer 10, respectively,
This allows the container load to be received and transmitted to other structural members.

In the embodiment described above, an example was shown in which the present invention was applied to a deck, but it goes without saying that the present invention can be similarly applied to parts of the hull where containers can be placed, such as a double bottom or a part of a hatch cover.

Further, in the above embodiment, an example was explained in which the curling material 15 was arranged in the trans direction, but of course the curling material 15 is not limited to this range.
For example, when horizontal members are arranged at short intervals in the transformer direction, the same effect can be achieved by providing canong members at predetermined positions on the left and right sides of the container securing hardware in a direction perpendicular to the horizontal members.

As mentioned above, the present invention embeds and fixes container lashing hardware in areas where there is no reinforcing member, such as the deck or double bottom plate, and curls the container lashing hardware on the lower surface of the deck, etc. and on the side of the stringer near the container lashing hardware. By fixing the top and both ends of the material, the container load can be transmitted to other structural members, so the deck surface, etc. can be supplemented, and the container lashing hardware can be placed so as to compete with the hull structure as in the past. There are no restrictions such as arranging containers, making it possible to arrange containers extremely efficiently.

In addition, according to this invention, the container lashing hardware only needs to be attached to the deck, and there is no need to support it on reinforcing members as in the past, or to connect the container lashing hardware to the reinforcing members via brackets, etc. Therefore, the structure itself is simple and inexpensive, and the installation work is also easy.

Furthermore, since the reinforcing member itself is not cut, there is no possibility that the strength of the hull will be insufficient.
