〔Example〕

An embodiment of the present invention will be described below based on the drawings.

In the figure, the floor panel 1 is constructed by attaching a floor base plate 3 to the upper surface of a steel surrounding frame 2 and a ceiling base plate 4 to the lower surface via a edging material 10, and by juxtaposing and constructing the floor panel 1. The upper floor F and the lower floor ceiling are formed.

The surrounding frame 2 is formed by joining a long vertical frame member 5.5 and a horizontal frame member 6.6 made of channel steel with flanges extending above and below the web into a rectangular shape with each groove facing inward. 4.5.6, narrow width portions 26 are formed at both ends of the horizontal frame material 6, and the narrow portions 26 are fitted into the grooves of the vertical frame material 5.
It is fixed using a bracket 14. Also, the horizontal frame material 6.6
In the middle, a reinforcing member 7.7 made of channel steel and having approximately the same length as the vertical frame member 5 has its webs abutted against each other, so that the frame is spanned. Note that narrow width portions are provided at both ends of the reinforcing member 7 in the same manner as described above, and the reinforcing member 7 is fitted into the groove portion of the horizontal frame member 6 and fixed using the five-shaped metal fittings 14.

Also, on the lower surface of the flange 6A under the horizontal frame member 6, there is a field edge 10.
A is attached at its end with a gap from the vertical frame member 5.

A support frame member 11 is mounted on the lower flange 5A of the vertical frame member 5 over almost the entire length of the vertical frame member 5, and is approximately halfway between the flange 5A and separated from the upper flange 5B. , the support frame member 11 is similarly attached to the flange 7A below the reinforcing member 7.

The joist 12 is a wooden material with a vertically long rectangular cross section, and both ends thereof have L-shaped notches 32 provided on the lower surface of the support frame material 1.
The rack is passed between the support frames 11, 11 by being fitted and supported in the upper part of the support frame 11.11.

The field edge 10 is made of wood with a rectangular cross section, and the horizontal frame material 6
Parallel to and below the joists 12, the frame is passed between the vertical frame members 5.5, and its ends are nailed. In addition, the horizontal frame material 6
The configuration of the lower field edge 10A is also formed substantially the same as the field edge 10 except for its length in the longitudinal direction.

In this example, the floor base board 3 and ceiling base board 4 are made of lightweight wood, such as gypsum board, concrete board, metal plate, a mixed board of cement and heat insulating material, or a mixture of synthetic resin with high-density granules. It consists of a plate-shaped body made of a material with a relatively high specific gravity compared to the . This can reduce the propagation of noise generated upstairs to downstairs.

In this example, the floor base board 3 has two boards 3A, an inner and an outer board.

3B are placed one on top of the other, and the board 3A is formed to a size that can be fitted into the space formed by the horizontal frame member 6.6, the vertical frame member 5, and the reinforcing member 7, and the board 3A is formed on the upper surface of the joist 12-. It's been hit.
