DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel capable of improving horizontal deformation resistance and fire resistance.

[0002]

2. Description of the Related Art A dry construction method of forming a wall, a floor, and the like of a house by using a panel in which a face material is attached to a framework in which a frame material is joined is frequently used. As illustrated in FIG. 3, for example, the frame includes a steel vertical bar A3 inside a peripheral frame formed by joining steel vertical frame members A1 and A2 and horizontal frame members B1 and B2 in a rectangular shape. And between the vertical crosspiece A3 and the horizontal frame members B1, B2, for example, wooden horizontal joist members B3...

On the other hand, when the floor panel itself is used as a strength member of a house or when the floor panel is large, it is necessary to increase the strength and rigidity of the floor panel itself. Conventionally, as shown in FIG. 3 described above, for example, a brace C is disposed in each area divided by the crosspiece A3 to reinforce the peripheral frame.

[0004]

However, when such a brace C is disposed inside the framework, the brace C3 is lifted by floating the joist B3 in order to avoid interference with the joist B3.
It is necessary to provide a space to pass through, or to arrange the brace C below the lower surface of the framework. In the former case, it takes time to produce such as complicating the production, and in the latter case, the brace C is moved from the lower surface. It protrudes and hinders the transport and handling properties, and also reduces the workability when installing on the spot.

An object of the present invention is to provide a floor panel capable of enhancing horizontal deformation resistance and improving fire resistance while facilitating production.
