Description

[Detailed description of the invention] (Industrial application field) This invention is applicable to transportation containers such as containers and van-type vehicles,
In particular, the present invention relates to a mounting structure for a heat insulating wall material that constitutes a wall such as a side wall or a ceiling of a transportation container.

(Prior Art) FIG. 5 shows a van-type vehicle in which the present invention is implemented, and FIG. 6 is a sectional view taken along line AA in FIG. 6th
As shown in the figure, the side walls a and the ceiling b are composed of so-called sanderch panels (hereinafter referred to as panel materials) 1 as a heat insulating material.

The panel material 1 consists of front and back surface materials 1a and 1b and a core material 1c between the surface materials, and this core material 1c is made of polyurethane foam or the like. Since such panel material 1 is lightweight and relatively high in rigidity, it has recently been used in large quantities for the walls of transportation containers and the like.

Conventionally, when combining, for example, a side wall a and a ceiling b of a transportation container using panel material 1 for the wall, the frame material 2 and panel material 1 constituting the joint c between the side wall and the ceiling.
To connect the panels, a fixing device such as blind rivets 3 is used, or adhesive 5 is applied to the groove formed by the frame material 2 and the backing plate 4, and the end of the panel material 1 is inserted there. It is common to combine them with .

Similarly, at the joint e between the side wall a and the floor d, the frame material 6 and the panel material 1 are fixed with rivets 3, or the floor d and the panel material 1 are fixed with the rivets 3 through the backing plate 7. Ta. Similarly, the front and rear corner posts and panel materials were connected using rivets 3.

Fixing devices such as blind rivets have the disadvantage that the fixing device tends to loosen. That is, since the transportation container is subject to severe vibrations and twisting during transportation, the fixing devices are likely to loosen. Once loosened, rainwater will infiltrate into the core material 1c of the panel material, and the insulation layer will react with the water, shrink and form clumps, which will not only significantly reduce the insulation effect, but also reduce the strength of the panel material. Significantly decreased.

In addition, the latter adhesive method has the problem that sufficient adhesive force cannot be obtained and sufficient strength as a box body cannot be obtained. That is, when inserting the panel material into the thin part of the frame material at the corner, a sufficient thickness of adhesive cannot be obtained, resulting in insufficient adhesive strength.

(Problem to be solved by the invention) In view of the shortcomings of the conventional structure, the present invention makes it possible to increase the thickness of the adhesive without using fixing devices such as blind rivets, thereby increasing the strength of the box. The object is to provide a mounting structure for panel materials that can be sufficiently obtained.

(Means for Solving Problems by Invention) In a transportation container in which the wall material is made of sanderch panels, and the side edges of the wall material are fixed to the frame materials such as the side frame materials and corner posts of the transportation container, A frame material with a hook-shaped part on the inside, a threaded part for inserting a bolt at one end, a hook-shaped piece that engages the hook-shaped part of the frame material in the middle part, and a wall material held at the other end. The hook-shaped piece of the panel support material is engaged with the hook-shaped part of the frame material, and the wall material is attached with an adhesive between the edge of the frame material and the panel support material. After clamping, a bolt is screwed into the bolt hole of the panel support material, and the bolt is firmly screwed into the inner surface of the frame material, so that the other end of the panel support material is moved around the engaging portion in the wall material pressing direction. I rotated it and pressed it to make it stick.

(Example) FIG. 1 shows a cross section taken along the line AA in FIG. 5, where the upper part shows a joint c between the side wall a and the ceiling b, and the lower part shows the joint e between the side wall a and the floor d.

The joint c between the side wall a and the ceiling b is composed of a plurality of members. 8 is an upper side frame member, and 9 is a panel support member used for supporting the upper inner side of the panel member 1 constituting the side wall and for supporting the inner end portion of the panel member 1 constituting the ceiling.

10 connects the end of the panel support member 9 to the upper side frame member 8
This is a bolt that is stretched against the inner protrusion of the Thus, the decorative board 11 is attached to the gap between the panel support members 9 attached to the upper side frame member 8, and the joint portion c is completed.

In addition, the joint part e connects the lower side frame member 12 and the lower support member 1.
3, and bolts 14 that extend the panel support member 13 against the lower side frame member 12.

Each member constituting the coupling portion c will be further explained based on FIG. 2. The upper side frame member 8 has a symmetrical cross-sectional shape, and the mounting side of the panel member 1 on the side wall a side and the mounting side of the panel member 1 on the ceiling b side are separated by 90° through a circular arc portion.

8a is a hook-shaped portion that engages with the hook-shaped piece 9b of the panel support member 9 that protrudes inside the upper side frame member 8; 8b is a protrusion that is also integrally molded inside the upper side frame member 8; This serves as the end abutment surface of the bolt 10 for pressing the material. 8c is a protrusion provided at the center of the upper side frame member 8, and a fitting groove 8d with unevenness in the longitudinal direction is provided at the center, into which the decorative board 1 is inserted.
The first protrusion 11a with projections and depressions is pushed in and fixed. It goes without saying that the protrusion 8c of the upper frame member 8 may be provided on the decorative board 11 side, and the protrusion 11a of the decorative board 11 may be provided on the upper frame member 8 side.

The panel support member 9 has a hook-shaped piece 9 in the middle portion of its main body portion 9a that engages with the hook-shaped portion 8a of the upper side frame member 8.
A threaded portion 9c is provided on the opposite side of the main body portion 9a, that is, on the top of the hook-shaped piece 9b, into which a bolt 10 is screwed.

Next, details of the joint portion e will be described based on FIG. A hook-shaped portion 12b that engages with a floor material end support portion 12a and a hook-shaped piece 13b of the panel support member 13 is integrally provided on the inside of the lower side frame member 12 and projects.

The panel support member 13 consists of a main body 13a, a hook-shaped piece 13b provided at the bottom of the main body 13a, and a threaded part 13c provided at the bottom of the hook-shaped piece 13b.

Next, based on FIG.
