Description

[Detailed Description of the Invention] The present invention relates to the roof structure of a container, and in particular, the roof rail portion in contact with the corner fitting is used to create a drainage channel for rainwater that accumulates in a recess provided at at least one end of the container roof in the longitudinal direction. The present invention relates to a structure that is formed by notching and is capable of effectively solving the problem of strength reduction caused by this.

Generally, when it comes to containers, measures against rainwater, etc.
In order to reinforce the roof plate, a recess lined with steel plates may be provided in the width direction at least at one longitudinal end of the container roof.

An example of such a container is shown in FIG. 1. In order to drain rainwater accumulated in a steel plate-covered recess 3 provided in an aluminum plate-covered roof 2 of the container 1, something is installed in the recess 3. It is necessary to provide such a drainage channel, and for this purpose, cutouts 6 are provided in the roof rails 4 on both sides of the container 1 in the longitudinal direction, near the portions that contact the upper corner fittings 5 of the container 1. Notch 6
When guiding rainwater etc. to the container side wall 7 through the corner fitting 5, the corner fitting 5 is the member that receives the most load during operations such as loading and unloading the container, and is a member that should be firmly connected to the container body. Despite this, the notch 6 reduces the joint area of the connecting portion between the roof rail 4 and the corner fitting 5, so it is inevitable that the joint between the two will be insufficient.

Furthermore, by forming such a cutout 6 in the roof rail 4, drainage water can flow down over the connection between the corner post 8 that supports the corner fitting 5 and the side wall 7 (which is usually riveted). As a result, rainwater enters the inside of the container through the gap between the connecting portions, and in severe cases, the problem of soiling the cargo occurs.

The present invention has been developed in view of the above circumstances, and includes providing a notch in the roof rail to drain rainwater that accumulates in the recess provided in the roof of the container, and connecting the container by forming the notch. Fix reinforcing material around the corner fittings where the strength has decreased to prevent the strength from decreasing, and also move the flow path of rainwater flowing down the side wall away from the joint where the side wall and corner post overlap and connect. By making it change to
It is designed to prevent rainwater from entering the container, and its features include a rectangular parallelepiped box-shaped exterior, and at least one longitudinal end of the upper roof. In a container in which a recess is formed in the width direction, a cutout is made near the part of the roof rail located in the longitudinal direction of the container that is attached to the corner fitting, and rainwater accumulated in the recess is drained from the side of the container. At the same time, a block of a predetermined size is placed in the notch and is fixed to both the corner fitting and the roof rail facing the notch, and the block is discharged from the notch. The reason is that rainwater and the like flow down the side wall surface of the container that is slightly away from the corner post that supports the corner fitting.

EMBODIMENT OF THE INVENTION Hereinafter, an embodiment of the present invention will be described in more detail based on the drawings.

In FIG. 2, a roof 2 of a rectangular parallelepiped-shaped container 1 is made of aluminum plates, and recesses 3 made of steel plates are provided at both ends in the width direction.

(Only one side is shown in the figure) The roof rails 4 on both sides of the container 1 in the longitudinal direction are each provided with a notch 6 in the vicinity of the portion that contacts the upper corner fitting 5 of the container 1. Rainwater or the like accumulated in the recess 3 can be discharged to the side of the container 1.

Further, a 1/4 cylindrical hollow block made of a steel plate or a solid steel block is made so as to be in contact with the side end surface 5a of the notch 6 of the corner fitting 5 and the corner fitting side surface 4a of the notched roof rail 4, respectively. A block 9 is attached by welding.

Note that this block 9 has two orthogonal faces, and is a triangular prism 9a whose cross section is a right triangle as shown in FIG. 3, or a pillar in which the slope of the triangular prism is replaced with a curved surface as shown in FIG. It may be a body 9b or a model block 9c as shown in FIG.

Furthermore, these blocks may be solid or hollow blocks made of steel plates or the like.

Furthermore, it is also possible to use a flat steel plate.

With this structure, rainwater on the roof 2 collects in the recess 3 and is prevented from flowing down toward the opening/closing door generally provided at the rear of the container 1. etc. are guided so as to flow down along the side wall 7 from the part of the notch 6 whose width is narrowed by the block 9.

Since this rainwater flow path is separated by the horizontal width of the block 9 from the joint (rivet line part) that connects the corner post 8 and the side wall 7, the flow of the rainwater is longer than when the block 9 is not installed. There is very little risk of rainwater entering the container from inside the container.

In addition, the problem that the force supporting the corner fitting 5 is weakened due to the notch in the vicinity of the part of the roof rail 4 that contacts the corner fitting 5 can be sufficiently compensated for by welding (fixing) the block 9. The problem was also successfully solved.

In addition, when the wedge-shaped block 9c shown in FIG. 5 is attached, the resistance to the flow of rainwater etc. in the notch 6 is reduced, resulting in an effect that the outflow becomes smooth.

As detailed above, the present invention is designed to prevent rainwater from flowing down from the roof toward the opening/closing door or the front of the container, and to strengthen the roof panels by draining water into a recess lined with steel plates. In order to provide a channel, the problem of reduced strength due to notching a part of the roof rail can be fully compensated for by fixing a small block with a simple structure. This has the excellent effect of effectively preventing rainwater from entering the container by moving the container away from the connection between the corner post and the side wall.
