DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partial cross-sectional view of the floor structure according to the present embodiment, in which a reference floor Fa on which a floor panel 2 is laid is adjacent to the reference bottom, and is higher than the floor panel 2 of the reference floor Fa. The low-floor portion Fb on which the low-floor panel 3 having a small height is laid is provided. In the present embodiment, a floor structure provided on an upper floor (above the first floor) of a house is exemplified.

The floor panel 2 disposed on the reference floor Fa
Is formed on a frame upper surface formed by joining a frame member 2a made of a channel steel having a U-shaped cross section, for example, with the grooves facing each other, and a face member 2b
Is formed as an integrally portable panel body. The low-floor panel 3 is also configured as an integrally portable panel body having a face member 3b attached to a frame upper surface formed by joining a frame member 3a made of channel steel in a rectangular shape with the groove portions facing each other. In the example, the one configured with a smaller thickness than the floor panel 2 is exemplified. In this example, both panels 2 and 3 are illustrated without any heat insulating material in the framework. The height hb from a reference position (not shown) to the upper surface of the low floor panel 3 is smaller than the height ha from the reference position to the upper surface of the floor panel 2.

In the present embodiment, the panels 2 and 3 are horizontally supported by beam members B on the upper floor via panel support fittings 12. The beam member B is made of a steel member having an I-shaped cross section and provided with a horizontal flange B2 above and below a vertical web B1. The panel support fitting 12 has a vertically long rectangular mounting piece 12A bolted to the web B1 of the beam member B, and each frame of the floor panels 2, 3 projecting horizontally from a substantially middle position in the vertical direction of the mounting piece 12A. A receiving piece 12B on which the members 2a and 3a are placed and bolted; a triangular reinforcing piece 12C connecting one side edge of the receiving piece 12B and one side edge of the mounting piece 12A below the receiving piece; Are provided as examples.

In this embodiment, since the thickness of the floor panel 2 and that of the low floor panel 3 are different, the lower surfaces of the panels 2 and 3 are supported on the beam B at the same height so that each panel is supported. Examples in which two or three upper surface heights are different are exemplified. Accordingly, it is not necessary to perform special construction on each panel, and the configuration of the panel support can be simplified, which is preferable in that the construction can be simplified. However, the present invention is not limited to such a configuration, and the thickness of the panel may be the same and the mounting position may be different.

The low floor section Fb has a heating floor section 6 on its upper surface. The heating floor section 6 includes a floor heating mat 4 capable of warming a floor finishing material 4a forming a floor surface, and the floor finishing material 4a interposed between the low floor panel 3 and the floor heating mat 4 to apply the floor finishing material 4a to the reference floor.
