Description

[Detailed Description of the Invention] The present invention relates to a top rail structure for ventilation containers that is integrally constructed by welding.It has a ventilator, and even when it is welded to the container after being subjected to anti-corrosion treatment such as painting in advance, the interior of the ventilator is That is, the container is characterized in that the paint and the like on the inside and outside communication parts are not burnt, so that corrosion does not occur in the inside and outside communication parts, and the container is extremely easy to manufacture.

Ventilated containers are used to transport perishable cargo such as fruits and vegetables that do not require refrigeration, or other cargo. Ventilation holes are provided at appropriate locations to communicate between the inside and outside, and these ventilation holes completely prevent rainwater from entering. The structure shall be designed to prevent

Traditionally, this type of ventilation container used a top side rail (or top front end rail).
is a square pipe, and an appropriate number of ventilation holes are provided on the bottom of the square pipe and outside of the side panel (or front end panel) attachment part, and an appropriate number of ventilation holes are provided on the inside side of the container of the square pipe to allow internal and external connections. The one that constitutes the communication part, or as shown in the fourth diagram,
A ventilation hole 21 is provided above the outer valley of the side panel 20 (or front end panel) of the corrugation, and a ventilation hole 23 is separately provided below from the top side rail 22 (or top front end rail) so as to cover the ventilation hole 21. There has been provided a cover 24 which is welded to form an inside/outside communication portion. 8 in the diagram is the roof panel, 15
is a baffle board.

However, in any of the above configurations, it is difficult to perform corrosion-proofing treatment inside the inside/outside communication portion.

In other words, the corrosion prevention treatment inside the above-mentioned interior and exterior communication parts is specifically painting, but in the case of the former, painting is applied to the inside of the square pipe that becomes the top side rail (or top front end rail) with ventilation holes. However, the internal coating is scorched by the heat during welding with the roof panel or side panel (or front end panel), and the internal corrosion protection effect cannot be obtained after all. Even if the side panel 20 (or front end panel) and cover 24 were painted, the results were similar to the former. This type of container is mainly used for sea transportation, and since salt-laden air enters and exits the interior and exterior communication areas, anti-corrosion treatment is particularly important.

In order to eliminate the above-mentioned drawbacks, a cover 24 etc. is attached by rivets or the like instead of welding after being painted in advance, but this requires time and effort to seal to prevent rainwater from entering. It has the disadvantages of being weak in strength, lacking in durability, and deforming when it collides with other parts during handling, reducing the sealing effect.

The present invention eliminates the above-mentioned drawbacks, and even if the roof panel, side panels, etc. are welded after being painted in advance, the paint inside the ventilator, that is, the interior and exterior communication parts, will not be scorched. The area where the paint has been burnt can be painted later, or may not need to be painted at all.

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an exploded perspective view of the container.

That is, a floor assembly 2 having bottom side rails 1 and 1a, side panels 3 and 3a erected on both sides thereof, a front end panel 4 erected at one end, a door frame 5 and a door 6 provided at the other end, and a side panel. It consists of top side rails 7, 7a of the present invention provided above the panels 3, 3a and a roof panel 8 attached above them. 1 in the diagram
6 is a corner fitting, and 17 is a corner post.

However, the present invention is not limited to the top front end rail 4 provided at the upper end of the front end panel 4.
It can also be used as a bottom side rail 1, 1a (or a bottom front end rail).

As shown in FIGS. 2 and 3, the top side rail 7 of the present invention (in the following explanation, the top side rail 7a will also be explained with the same reference numeral) is provided with an appropriate interval on the bottom surface of the top rail 9 made of a square pipe. The outer plate 10 and the inner plate 11 are welded together, and a ventilation hole 12 is provided below the outer plate 10, and a ventilation hole 13 is provided above the inner plate 11.

They are preferably welded to the top rail 9 after providing ventilation holes 12 and 13 in the outer plate 10 and inner plate 11 in advance.

Next, a square pipe 14 similar to that of the top rail 9 is welded to the lower ends of the outer plate 10 and the inner plate 11, so that the entire structure is integrated.

In the figure, 15 is a baffle plate. The top side rails 7, 7a having the above structure are subjected to anti-corrosion treatment in advance.

That is, the top side rails 7, 7a are immersed in paint for corrosion protection, and after waiting for the paint to dry, they are welded to the roof panel 8 and side panels 3, 3a (a and b) as shown in the third figure.

At this time, in the case of the present invention, the roof panel 8 and the side panels 3, 3a are welded to the top rail 9 made of a square pipe and the square pipe 14 provided below, and as a result, the roof panel 8 and the side panels 3, 3a are welded together. The interior of the ventilator, that is, the outer panel 10 and inner panel 11, will not be heated by the heat of the time, and therefore the paint inside will not be scorched and the anti-corrosion effect will not be reduced. It is.

Note that during the above-mentioned welding, the paint applied to the outer and inner surfaces of the top rail 9 and the square pipe 14 made of square pipes is burnt, but the outer surfaces can be pretreated and completely repainted afterwards, and the inner surfaces can be completely repainted. is fine as is.

That is, when both ends of the top rail 9 and the square pipe 14, which are made of square pipes, become containers, corner fittings 16 or corner posts 1 are used.
7 and is airtight, and no air enters or exits, so even if the interior coating is incomplete, it will not corrode.

As mentioned above, according to the present invention, the ventilator can be constructed strongly by welding, and the interior of the ventilator is completely corrosion-resistant and unaffected by the heat generated during welding with other parts, resulting in durability. Furthermore, since the top rail and the ventilator are integrated in advance, the container can be manufactured easily.
