Description

[Detailed Description of the Invention] The present invention relates to a container roof structure in which a new idea is added to the brackets, roof rails, headers, etc. that are easily damaged around the upper corner fittings of the container.

Generally, when transporting containers, cranes, spreaders, etc. are used to load and unload them onto vehicles, ships, etc. However, as shown in Figures 1 and 2, when the spreader 2 is brought close to the container 1, an error occurs. This could cause the lifting tool to collide with the roof of the container, causing damage to the roof panel.Also, since the structure around the corner fittings 3 was complex and relatively unsturdy, there was a risk of rainwater leaking due to collisions, etc. be.

In order to eliminate such damage caused by roof damage, a roof structure as shown in FIGS. 3 and 4 was proposed in Japanese Utility Model Publication No. 51-38574.

This means that the roof plate portion 4 (hereinafter simply referred to as the header) around the upper corner fitting 3 is made one step lower than the top surface of the corner fitting 3, and the roof rail 6 fixed to the corner fitting 3 via the bracket 5 is made one step lower. The length of the header 4 is cut out to make it shorter, and the header 4 is riveted to the bracket 5.

By doing so, the lifting tools of the spreader 2 and the lower corner fittings of other containers would not directly hit the roof panels and cause damage during loading and unloading of the container.

However, since the roof rail 6 is still extended to the vicinity of the corner fitting 3 and riveted to the bracket 5, the following problems occur.

That is, since the roof rail 6 is a long member along the longitudinal direction of the container, it is made of an aluminum profile or a roll-formed thin steel plate to reduce weight, and it is difficult to weld it to other parts, so it is difficult to weld it to other parts, so it is difficult to connect it with rivets. is used, resulting in a structure that does not have sufficient water leakage prevention function.

Moreover, in this riveted connection, sealing material is inserted into both sides of the side plate 7 sandwiched between the bracket 5 and the roof rail 6, as shown in FIG.
If a heavy lifting tool such as a container collides with the vicinity of the joint, the vicinity of the joint may be deformed, distorted, or damaged, and rainwater or the like will pass through the inside of the side plate 7 and enter the inside of the container.

Additionally, replacing damaged roof rails required significant time and repair costs.

In addition, as a problem when assembling the container, in order to assemble the side post 8, roof bow 9, etc. to the roof rail 6, it is necessary to move the roof rail 6 laterally and insert it close to the corner fitting. The applied sealant twisted and created a gap, which caused water leakage.

Furthermore, it is not an easy task to accurately cut out the upper half near both ends of the roof rail 6, which inevitably increases the number of man-hours, and there is no complete measure to prevent water leakage due to the notches. There were disadvantages such as not being able to obtain

In order to eliminate the above-mentioned drawbacks of the prior art, the present invention has been developed by fixing a lightweight roof rail to the corner bracket at a considerable distance from the corner bracket instead of placing it close to the corner bracket, and by installing a relatively thick wall around the corner bracket. Welded structure made of steel etc. to increase strength,
This was done with the purpose of preventing roof damage and water leakage, and its gist is that a steel header that extends inward to a considerable extent in the longitudinal direction of the container roof is installed at the longitudinal end of the container roof to extend the width of the container. In the costena, the roof rail is provided one step lower than the top surface of the corner fittings in the longitudinal direction of the container roof, and the roof rails arranged between the corner fittings in the longitudinal direction of the container roof are attached to the corner fittings via brackets. A gusset whose cross section is box-shaped or a part of a box is welded and fixed to the header, and a container longitudinal side is integrally welded to the gusset or formed integrally with the header. A bracket member extending further inward is provided, and the roof rail is fixed to the bracket member with rivets.

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

In FIGS. 5 to 7, a steel header 4 is provided which extends inward to a considerable extent from the longitudinal end of the roof of the container 1, and this head 4 extends from the top surface of the steel corner fitting 3. The height is lowered one step by 11, and a lower part is formed inwardly from the inner surface of the corner fitting 3 by a length of 12.

The gusset l-5a that supports the header 4 from below by the length of the above-mentioned 12 is made of a thick steel plate, and its cross section does not have the shape of a box or a part of a box (see Fig. 6), and the header 4
It is also welded to the inner surface of the corner fitting 3, extends downward for a considerable length, and is welded to the corner post 10 for a certain length to be fixed sufficiently firmly.

In addition, there is a blind cover 5'a on the opposite end of the corner fitting 3 side.
are welded together to form a sealed box.

A steel bracket member 5b extending further inward is welded and fixed to the blind lid 5'a.
A roof rail 6 is riveted to b.

As shown in FIGS. 5 and 7, the sagging roof rail 6 has a side plate fixing part 6 that extends downward and to which the side plate 7 is fixed.
a, a roof plate fixing part 6b that extends in the horizontal direction and to which the roof plate 20 is fixed, and a connecting part 6C that connects these parts.

Further, a hanging portion 6d and a horizontal portion 6e extend downward and laterally from the connecting portion 6c, respectively.

The hanging portion 6d and the horizontal portion 6e each extend to the vicinity of the side end surface of the bracket member 5b.

That is, one end of each of the hanging portion 6d and the horizontal portion 6e is positioned inward (to the right in FIG. 5) by the width of the bracket member 5b from the blind lid 5'a.

As shown in FIG. 7, the bracket member 5b is bent along the back surface of the side plate fixing portion 6a and the connecting portion 6C of the roof rail 6, and its upper end portion extends along the roof plate 20. There is.

The bracket member 5b and the roof rail 6 are connected by rivets.

In this way, the roof rail 6 has a length of 1 between it and the corner fitting 3.
It is riveted to the bracket member 5b with a distance of 2.
All of the parts a are made of thick steel and are welded together, and the periphery of the corner fitting 3 is assembled into a strong welded structure.

Therefore, even though the area around the corner fitting 3 is lowered, even if the hanging fittings of the spreader 2 further descend and collide with the area around the corner fitting 3 and give an impact, the header 4,
The gusset 5 and its joints are almost never deformed, distorted, or damaged, and even if they are deformed by a direct collision with the spreader 2, they can be joined by welding. In addition, it is possible to effectively prevent the gap between the bracket and the header as in the prior art, and the problem of water leakage has been completely eliminated.

Furthermore, even if there is slight damage, since all the components are steel, it is easy to cut and weld, and repair work is simple.

Furthermore, roof rails 6 are installed to reduce the weight of the container 1.
Even if it is made of an aluminum profile or a roll-formed thin steel plate and lacks rigidity, it is fixed at a position far enough from the corner fitting 3 that there is no risk of water leakage due to deformation due to impact, etc. be.

Since the roof rail 6 stops at the inner end of the header 4 in the longitudinal direction of the container and does not extend below the header as in the conventional example, it is also necessary to cut out a large portion of the upper half of the roof rail 6 near both ends. Furthermore, since it is only necessary to cut out the hanging part 6d and the horizontal part 6e of the roof rail 6 when connecting it to the bracket member 5b, the entire upper half of the part corresponding to the length of several headers can be accurately cut out, as in conventional roof rails. This work is easier than cutting out the roof rail (so that there is no gap between it and the header), and it is also easier to move both ends of the two roof rails laterally and insert and assemble them so that they are close to the corner fittings 3. Since there is no need to do this, there is no risk of the sealing material twisting and causing water leakage.

In the above-mentioned embodiment, the gasket 5a and the bracket member 5b are welded together as separate bodies for convenience in processing and economy of materials, but the present invention is not necessarily limited to this. , gusset 5a and bracket 5
There is no problem even if it is formed integrally with b.

In addition, the gasket 5a is attached to the header 4 as shown in FIG.
It takes on a box shape only when it is welded to the box, and although it itself forms part of the box, the gasset) 5a
Of course, the box itself may be a box.

As described in detail above, the present invention fixes a lightweight roof rail at a considerable distance from the corner fittings, and uses a welded structure made of a material such as steel with the area around the corner fittings lowered one step. Modification 1: Eliminates damage, reduces container repair costs, eliminates the risk of water leakage, and also cuts out the upper half near both ends of the roof rail, which is positioned below the conventional header. This has the effect of eliminating assembly problems such as inserting the sealing material close to the corner fittings and inducing twisting of the sealing material, which may cause water leakage.
