BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block floor plate for an automobile, which constitutes a floor portion of a truck or a container.

[0002]

2. Description of the Related Art Up to now, floors of trucks and containers have been formed by sticking floor materials to joists fixed on a chassis. There are woods produced from South Sea) and plywood. Then, after arranging all of these floor materials on the joists, they are fixed by hammering nails from the surface side of the floor material.

However, in the floor portion formed by using the plywood board, there is a problem that the strength against load is insufficient, so that the floor board used most in quantity at present is the Apiton material. It has been processed. This apiton wood is very suitable because it has sufficient strength and moderate elasticity as a floorboard for automobiles, but recently, it has been deforested in various places to obtain apiton wood. However, it has become a global problem because it leads to the destruction of tropical rainforests, and the development of flooring materials that solve these problems is desired.

Therefore, without using the Apiton material,
Aluminum has been studied as a floor material that can achieve a reduction in the weight of the floorboard, and aluminum floorboards for automobiles have also been proposed, but the plate-shaped aluminum floorboard does not have sufficient strength and elasticity. Since there are not so many, the surface is likely to be dented by impact and it is necessary to make it a thick plate. It also has the drawback of being expensive.

Further, in the case of a truck, there is a problem in that, when it rains, the water that has risen from the lower side of the bed passes through the floor plate and reaches the top of the bed. To solve such a problem, Until now, floor boards have been double-bonded, and iron plates and plastic plates have been attached under the floor boards. However, with such a structure, many rivets are required to fix the floor plate, and therefore the work of attaching the floor plate is very troublesome. In addition, the double structure of the floor has a drawback that the weight of the floor itself increases. As mentioned above, there has been no proposal for an automobile floorboard suitable for forming a floor portion of a truck or a container.

[0006]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems and makes it possible to inexpensively use an Apiton material without using it.
Moreover, it is an object of the present invention to provide a floor plate for an automobile that can easily perform the work of attaching the floor plate.
