DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a sandwich panel for a vehicle. In particular, the present invention relates to a structure of a sandwich panel for a van body having a longitudinal groove for mounting a lashing rail or the like.

[0002]

2. Description of the Related Art When a lashing rail (a) is mounted in a van body formed of a conventional sandwich panel (FIG. 5), an inner surface plate (b) of the sandwich panel is thinned. Then, in order to secure the strength of the attachment portion of the lashing rail a, it is necessary to arrange the wood c on the core material portion of the corresponding place or attach a reinforcing material d as shown in FIG. 4B to the surface of the sandwich panel. Was. Further, if the lashing rail a protrudes inside the warehouse in this manner, the cargo may be damaged, and if it is not desired, the lining plate b inside the warehouse needs to be raised. However, when such measures are taken, there are drawbacks such as that the weight of the body becomes unnecessarily heavy, and that the effective width in the refrigerator becomes narrow.

[0003]

A part of the sandwich panel is recessed so that a lashing rail or the like can be attached.
Further, an object of the present invention is to provide a lining plate for a van body in which a lashing rail can be embedded in this portion, and to provide a sandwich panel capable of securing an inner width and sufficiently guaranteeing strength.

[0004]

Means for Solving the Problems 1) In a van body having a side wall formed by using a sandwich panel 1 having a longitudinal groove 5 for mounting a lashing rail or the like on an inner surface thereof, the sandwich panel 1 has an outer plate 2 And core 3
And an inner plate 4, wherein the outer plate 2 is bonded to the outer surface of the core material 3 and the inner plate 4 is bonded to the inner surface of the core material 3.
Is composed of an upper plate 4a having a Z-shaped bent portion 6a at the end and a lower plate 4b having a Z-shaped bent portion 6b at the end, and the Z-shaped bent portions 6a and 6a of the upper plate 4a and the lower plate 4b. 6b is the core material 3
Are superimposed and bonded on the concave groove 5a provided in the above. 2) When a plurality of rows of concave grooves 5 are required, an intermediate plate 4c having Z-shaped bent portions 6c at both upper and lower ends is arranged between the upper and lower concave grooves,
The Z-shaped bent portion 6a of the upper plate 4a and the Z-shaped bent portion 6c of the middle plate 4c are overlapped on the concave groove 5a of the core member 3, and the Z-shaped bent portion 6c of the middle plate 4c and the lower plate 4b The Z-shaped bent portions 6b are overlapped and bonded. Further, by setting the depth of the concave groove 5a of the core member 3 described in the above 1) or 2) according to the thickness of the lashing rail 7, it is possible to eliminate the protrusion from the inner wall surface of the vehicle and increase the inner width. I made it possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. As shown in FIG. 1, a sandwich panel 1 according to the present invention includes an outer plate 2, a core material 3, and an inner plate 4, and is connected to each other by an adhesive. As the outer plate 2, a thin plate such as an aluminum plate or FRP is used, and a single plate is usually preferable.

As the core material 3, foamed plastics are used, and as shown in FIG. 1A, a concave groove 5a having a normal width a and a depth b is formed. The concave groove 5a may be formed by engraving the center of the foamed plastic plate 3 as shown in FIG. 3A, or may be formed by abutting two plates whose ends are cut off as shown in FIG. 3B.

The inner plate 4 is made of aluminum, painted steel plate or the like, and when the grooves 5 are arranged in only one row, as shown in FIG.
And a lower plate 4b. When there are a plurality of concave grooves 5 in two or more vertical rows, there is another middle plate 4c outside the upper plate 4a and the lower plate 4b, and these are combined. In the example of FIG. 3B, upper and lower two rows of concave grooves 5 are formed. The upper plate 4a and the lower plate 4b constituting the inner plate 4 have their edges bent in a Z shape (the bending angle is 90 °) to form Z-shaped bent portions 6a and 6b. It overlaps on the top. At the overlapping portion, an adhesive is applied in advance, and pressure bonding is performed to form one sandwich panel. In this case, the upper and lower Z-shaped bent portions at the overlapping portion are 2
It becomes heavy and becomes a reinforcement structure.

In the case where a plurality of rows of concave grooves 5 are provided, FIG.
A middle plate c between the upper plate 4a and the lower plate 4b
The same effect can be obtained by arranging. As the end shape of the inner plate 4, in addition to the example described above, a shape in which a flange bent at a right angle is provided at the end of the Z-shaped bent portion is also considered.
It can be used properly depending on the reinforcement application.

[0009]

By manufacturing a sandwich panel having a concave groove, the lashing rail and the like do not protrude inward, so that the effective inner width can be increased. or,
A portion requiring strength can be reinforced by overlapping the ends of the inner plate 4. Therefore, since another reinforcing member is not required for the concave groove portion, the weight can be reduced. Furthermore, adhesive application, which is a sandwich panel manufacturing process,
Since the reinforcement is performed in the subsequent pressurizing step, the number of manufacturing steps can be reduced as compared with other mounting methods of the reinforcing member.
