BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a perspective view showing an example of the floor-assembly horizontal member according to the present invention, and FIG. 2 is a cross-sectional view showing a state in which a floor plate and a heat insulating panel are placed on the upper surface of the floor-assembly horizontal member.

The floor assembly horizontal member 1 is composed of a rod-shaped metal shape member 2, a heat insulating member 3, and a rod-shaped wood 4.

The metal profile 2 is a rod-shaped profile having a holding portion 20, a groove 5 and an overhang 6.

The holding portion 20 may be formed in a groove shape in cross section which opens upward, but in this embodiment, the bottom plate 2a.
And the side plates 2b, 2 which stand upright from the side end of the bottom plate 2a.
and b have a groove-shaped cross section. The upper end of the side plate 2b is located below the upper surface of the wood 4. Further, in this embodiment, the protrusions 2c, 2c protruding above the bottom plate 2a are formed. The protrusion 2c is for stably fixing the wood 4 to the metal profile 2.

The groove 5 has a U-shaped cross section and is formed at the upper end of the side plate 2b (upper end of the metal profile 2).

The projecting portion 6 is formed by horizontally projecting outward from the side plate 2b. The height position of the overhanging portion 6 is adjusted to the installation height of the heat insulating panel 8 laid on the lower surface of the floor plate 7.

The metal profile 2 is an extruded profile made of aluminum alloy. This makes it possible not only to easily form the cross-sectional shape described above, but also to take advantage of the advantages of the aluminum alloy that it is light in weight for its strength and is resistant to corrosion.

The heat insulating member 3 is mounted in the groove 5 formed at the upper end of the metal profile 2. The heat insulating member 3 is made of a material such as rubber, styrofoam, urethane, etc., which has a smaller thermal conductivity than the metal profile 2. When the floor plate 7 is laid, the heat insulating member 3 is attached such that the upper end of the heat insulating member 3 is flush with the upper surface of the wood 4 so as to contact the lower surface of the floor plate 7 (see FIG. 2). If the heat insulating member 3 is made of a relatively soft material such as urethane, the heat insulating member 3 is attached so that its upper end protrudes above the upper surface of the wood 4, and the heat insulating member 3 is compressed when the floorboard 7 is laid. It may be made to be flush with the upper surface of the wood 4.

The wood 4 has a quadrangular cross section and is fitted between the projections 2c and 2c provided on the bottom plate 2a of the metal profile 2. Further, the upper surface of the wooden piece 4 is made to project above the upper end portion of the metal profile 2.
