Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a container, a container for a van type vehicle, and the like, and more particularly to a mounting structure for a heat insulating wall material constituting a side wall of the container and a ceiling wall. .

(Prior Art) FIG. 3 shows a van type vehicle in which the present invention is implemented, and FIG. 4 is a sectional view taken along line AA in FIG. As shown in FIG. 4, the side wall a and the ceiling b are made of so-called sandwich panel (hereinafter referred to as panel material) 1 as a heat insulating material.

The panel material 1 includes front and back surface materials 1a and 1b and a core material 1c between the surface materials. The core material 1c is made of polyurethane foam or the like. Since such a panel material 1 is lightweight and has relatively high rigidity, it has been used in large quantities in the wall portion of transport containers and the like in recent years.

Conventionally, when, for example, a side wall a and a ceiling b of a transport container using the panel material 1 for the wall portion are combined, the frame material 2 forming the joint portion c between the side wall and the ceiling is connected to the panel material 1 by a blind rivet 3 or the like. It is usual to use a fixing tool, or to apply an adhesive 5 to a groove formed by the frame member 2 and the backing plate 4, and insert the end of the panel member 1 into the groove to bond the panel member 1 and the like.

Similarly, also at the joint portion e between the side wall a and the floor d, the frame material 6 and the panel material 1 are rivets 3 or the floor d and the panel material 1 are used.
And were fixed with the rivet 3 via the contact plate 7. Similarly, the rivets 3 were used to connect the front and rear corner posts to the panel material.

Those fixed with rivets or the like have a drawback that the fixing tool is easily loosened. That is, the transportation container is subject to severe vibrations and twists during transportation, and thus the fastener is easily loosened. Once relaxed, rainwater infiltrates into the core material 1c of the panel material from here, and the heat insulation layer reacts with water and contracts and agglomerates, not only significantly reducing the heat insulation effect but also the strength of the panel material. Markedly reduced.

Further, the latter bonding method has a problem in that sufficient adhesive force cannot be obtained and sufficient strength as a box cannot be obtained. That is, when inserting the panel material into the groove portion of the frame material at the corner,
The adhesive strength is insufficient because the thickness of the adhesive cannot be obtained sufficiently.

(Problems to be Solved by the Invention) In view of the drawbacks of the conventional configuration, the present invention allows the adhesive to have a sufficient thickness without using a fixing tool such as a blind rivet, and thus has a sufficient strength of the box body. It is intended to provide a mounting structure for the obtained panel material.

(Means for Solving the Problems by the Invention) In a transport container in which a sandwich panel is used as a wall material, and side ends of the wall material are fixed to a frame material such as an upper side frame material and a corner post of the transport container, a pair of hooks is provided.
