Abstract

PURPOSE:To reduce weight and increase the loading capacity by obtaining a sandwich-shaped composite member, having a counter-core panel consisting of a balsa wood, between two surface members which are constituted of the light metal plate such as aluminum and constituting the whole or a part of the regional surface of the box-shaped load carrying platform of a truck from the composite member. CONSTITUTION:Two pieces of surface members 1 made of the light metal (a) such as aluminum are arranged vertically keeping a prescribed interval, and a counter-core panel 3 which is formed by arranging a balsa wood 2 cut to a proper block so that the fiber direction crosses at right angle with the surface member 1 is nipped, and a sandwich-shaped composite member 5 is formed by the integral formation of the counter-core panel 3 and the surface member 1 through an adhesive 4. The panel of the box-shaped load carrying platform of a truck is formed by using such the composite members 5. Accordingly, the loading capacity of the box-shaped load carrying platform can be increased, and the reduction of weight can be realized. Further, since the panel can be formed flat, the outside appearance can be improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a truck panel which forms a cargo bed of a truck and which has light weight, impact resistance, heat insulation and water resistance.

[0002]

2. Description of the Related Art In many cases, conventional panels forming a box carrier of a truck are made of an aluminum material and have a corrugation aluminum plate as a surface material on a frame structure.

[0003]

However, in the truck body structure as described above, the heat insulation is poor and the temperature inside the box carrier easily rises, which affects the temperature of the loaded products.
Moreover, since the panel itself basically adopts a frame structure, the panel thickness is inevitably thick, and accordingly, the loading space is reduced and the loading amount and the loading are limited.
At the present time, the body itself is also weighted.

In view of the above situation, it is an object of the present invention to provide a truck panel having a heat insulating performance, an increased load capacity, etc. by using a sandwich-like combination of an aluminum material and a balsa material. It is a thing.

[0005]

According to the present invention, a canter core in which a balsa material is arranged between two surface materials made of a lightweight metal plate such as aluminum so that the fiber direction of the balsa material is orthogonal to the surface material. A sandwich type composite material is formed by sandwiching the panels, and the composite material constitutes the entire surface or a part of the surface of the box carrier of the truck.

Further, the box carrier is provided with wings, swing plates,
These include rear panels, floorboards, front panels and van-type truck bodies.

[0007]

As described above, a sandwich type composite material in which the panel structure is made of a lightweight metal plate such as aluminum as a surface material, and the surface material is disposed on the upper and lower surfaces and a balsa material is sandwiched in the middle so that the fiber directions thereof are orthogonal to each other, Since it is a panel for trucks, the panel itself is lightweight, strong in impact resistance, and has excellent heat insulation and water resistance. The thickness is thin, the space is expanded correspondingly, the weight of the track body itself is reduced, the heat insulating effect is good, and the temperature rise in the box is minimized.

In this case, the box carrier may be entirely formed of this panel, or may be partly used as a wing, a tilting board, a rear panel (a double door), a floor board, a front plate, or the like.

[0009]

The present invention will be described below with reference to the drawings of the embodiments.

As shown in FIG. 1, reference numeral 1 denotes a surface material of a lightweight metal plate a made of aluminum. Two surface materials 1 are arranged vertically at a predetermined interval, and in between, a block is appropriately formed. The cut balsa material 2 is sandwiched between a canta core panel 3 formed by arranging the fiber directions 2a so as to be orthogonal to the surface material 1, and the canta core panel 3 and the surface material 1 are integrated with an adhesive 4. Sandwich type composite material 5
The overall structure of these products is lightweight, impact resistance, heat insulation,
The truck panel 5'is water resistant.

The operation will be described. First, as an aspect of the truck panel 5 ', for example, as shown in FIG. 2, the truck panel 5'can be used on the entire wall surface of the box carrier 6 which is a van type truck body, or as shown in FIG. As shown in FIG. 3 and FIG. 4, it is used for all or a part of the wing 7, the tilt plate 8, the gannon door type rear panel 9, the floor plate 10, the front plate 11 and the like in the wing tilt type truck.

Here, this truck panel 5 '
Has a very high rigidity because the balsa material 2 serving as the core material is arranged so that the fiber direction 2a is orthogonal to the surface material 1.
The thickness s of the panel itself can be reduced. For this reason, the load capacity of the box carrier 6 is expanded by the amount corresponding to the decrease in the wall thickness, and it is possible to load more than the conventional one.

Further, since this panel 5'is a composite material 5 of the balsa material 2 and the surface material 1 of an aluminum plate, it is less susceptible to temperature changes than the conventional box carrier consisting of an aluminum plate and a frame, and is a core material of the panel. The heat insulation of a certain balsa material 2 itself,
The heat-retaining property plays a role of keeping the temperature inside the box carrier of the truck constant, and it is also most suitable for the car carrier part of a refrigeration vehicle or the like.

By the way, if a comparison of the temperature change between the box carrier using the panel of the present invention and the conventional panel mainly made of an aluminum plate is shown, a graph as shown in FIG. 5 is obtained.

That is, it can be seen that the conventional panel mode causes fluctuations that follow changes in the outside air temperature, while the panel mode of the present invention does not undergo much change and maintains a constant value.

[0016]

As described above, the truck panel of the present invention is a composite material in which the balsa material is sandwiched between the surface materials (surface layers) of a lightweight metal plate such as aluminum so that the fiber directions thereof are orthogonal to each other. By using as a truck panel, the total thickness of the panel is reduced to significantly increase the loading capacity, reduce the influence of the temperature of the loaded products, reduce the weight of the truck body itself, improve the appearance of the truck due to the smooth surface, and paint. It has effects that it can be simplified, upgraded when a truck body is used as an advertising surface, and can be used for a refrigeration van body to increase the strength of the panel itself and simplify and reduce the number of steps in the truck assembling process.
