DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel structure using a folded plate.

[0002]

2. Description of the Related Art Folded plates have increased strength in a direction perpendicular to a surface by bending, and are often used as floor members subjected to a vertical load. However, the folded plate has directionality, and there is a problem that the in-plane rigidity is weak in directions other than the folding curve direction. That is, when a horizontal force is applied from a direction different from the folding curve direction, the horizontal portion is easily opened at the bent portion, so that the horizontal force cannot be supported.

For this reason, in a conventional floor using a folded plate, concrete is further poured or a horizontal brace is used to impart horizontal force.

[0004]

However, the method of placing concrete requires a large amount of construction work on site and a long construction period. On the other hand, even if a horizontal place is separately provided, the man-hour is correspondingly increased. In the case of (1), there is a disadvantage that the cost is high.

[0005] The present invention solves such conventional disadvantages, and has high in-plane rigidity and excellent sound insulation.
It is an object of the present invention to provide a floor panel that can be constructed by a dry method.

[0006]

In order to solve the above-mentioned problems, the present invention provides a valley-side surface of a folded plate with at least in-plane rigidity in a direction perpendicular to the direction of the folding curve of the folded plate. It is characterized by laminating plate-like materials.

[0007] In the above, according to the invention of claim 2 of the present application, the plate-shaped material is an iron plate or another metal plate.

Further, in the invention of claim 3 of this application, the valley space surrounded by the folded plate and the plate-like material is filled with a material having a large mass, for example, waste paper, gypsum or other waste material.

In the above, the folded plate is preferably one in which a plurality of rib-shaped protruding pieces formed by folding back to one surface side are formed at intervals. The tip of the piece may be bent into an L-shape or T-shape.
