 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 4, a base 2 is provided on the upper surface of the basic concrete 1, and a support base 4 called Daihiki is provided on the upper surface of the concrete base 3. As shown in FIG. 3, a plurality of floor panel bodies 5 and 5A are arranged side by side on the base 2 and the support 4. The plane of the floor panel 5 is almost tatami-sized, and the frame members 7 are arranged on four sides of the upper plate 6 made of plywood and the lower plate 8 made of plywood is provided below the frame member 7. A heat insulating material 9 such as urethane foam is provided inside these.

The end faces that abut the floor panel bodies 5, 5A will be described. The end surface of the floor panel body 5 on the negative side has a negative slope 10 formed by the frame member 7 so that the lower portion projects from the upper portion. On the end surface of the floor panel body 5A, the other side slope 10A is formed by the frame member 7A so that the upper part projects from the lower part. The other side slope 10A is formed so as to engage with the negative slope 10. There is. A concave portion 11 is provided substantially in the center of the − side inclined surface 10 along the width direction of the − side inclined surface 10, and a convex portion 12 that fits into the concave portion 11 is formed substantially in the center of the other side inclined surface 10A. Are provided along the width direction. The recessed portion 11 is composed of a recessed bottom surface portion 13 and a recessed sloped surface portion 13A which is formed obliquely upward from the back portion 15 side of the recessed portion bottom surface portion 13 to the other side. The recess central axis 16 connecting the inner part 15 and the center of the opening 14 is directed obliquely upward to the other side. On the other hand, the convex portion 12 has a base end 18 formed larger than the distal end 17 so that the convex bottom surface portion 12A engages with the concave bottom surface portion 13 and the convex slope surface portion 12B engages with the concave slope surface portion 13A. Has been formed. The central axis 19 of the convex portion connecting the centers of the distal end 17 and the proximal end 18 is directed obliquely downward to the negative side. The directions of the central axes 16 and 19 should be substantially the same as the tangent line of the virtual arc 21 when a circle is drawn around the upper end of the end surface of the minus side panel body 5, that is, the upper corner portion 20 of the upper plate 6. It is set. The convex portion 12 is provided by fixing a linear wood 24, which is called a diamond-shaped product, to a groove 23 formed in a triangular shape in the frame member 7A by adhesion or the like.

On the other hand, the portions of the floor panel bodies 5 and 5A facing the base 2 are vertically formed to have vertical end faces 25 and 25A. The vertical end surfaces 25, 25A are mounted on the lower horizontal portion 28 of an iron hook 27 having an upper horizontal portion 26 fixed to the base 2. An elastic packing 29 is provided between the hook 27 and the vertical end faces 25, 25A.

Next, the operation of the above configuration will be described. First, the floor panel body 5 is installed as shown in FIG. At this time, the vertical end face 25 side is placed on the lower horizontal portion 28 of the hook 27 whose upper horizontal portion 26 is fixed by the nail 30 in advance, and the portion is fixed by the nail 31. Next, nails 32 are struck from the bottom surface 13 of the recess to fix the floor panel body 5 to the support 4. Then, when the upper corner portion 20A of the floor panel main body 5A is butted against the upper corner portion 20 and the floor panel main body 5A is inserted between the − side slope 10 and the hanging metal fitting 27A on the other side, the convex portion 12 becomes a virtual arc 21. It rotates along with and is inserted from the opening 14 and fitted into the recess 11. At this time, the packings 29, 29A may be slightly compressed to insert the floor panel body 5A.

In the state where the floor panel bodies 5 and 5A are arranged side by side in this way, as shown in FIG. 1, the slope 12B of the protrusion 12 is engaged and pressed against the slope 13A of the recess 12.
