  On the two sides composed of the short side and the long side of the floor base material 2, a receiving portion 8 for installing the overlapping portion 7 of the other floor base material 2 is formed. The overlapping portion 7 to be installed on the floor base material receiving portion 8 is formed, and this overlapping portion 7 is installed on the receiving portion 8 of the adjacent floor base material 2 to join the floor base materials 2 together. Moreover, three (any number if necessary) of hard synthetic resin piers 9 are embedded on the upper surface of the floor base material 2 along the short side direction.

  On the other hand, as shown in FIGS. 2 and 3, the support leg 3 that supports the floor base material 2 is a flat circular fixed plate 11 that is installed at the lower end of the column base 10 and is fixed to the upper surface of the slab. And a flat circular mounting plate 12 which is installed at the upper end of the column base 10 and on which the floor base material 2 is mounted, and the male screw portion 14 in the reinforcing rib 13 of the mounting plate 12 is connected to the male column base. The mounting portion 12 is movable up and down by screwing the screw portion 15, and a hexagon socket nut 16 is formed on the upper portion of the female screw portion 14.

  For this reason, by inserting a hexagon wrench 17 as an operation rod into the hexagon socket nut 16 and rotating it, the mounting plate 12 moves the column base 10 up and down to adjust the unevenness, that is, the level adjustment of the floor base material 2. Can be done.

  Further, the upper plate 20 and the mounting plate 12 are fitted in the installation concave grooves 18 and 19 on the upper and lower surfaces of the floor base material 2, and the upper plate is inserted into the through hole 21 opened between the installation concave grooves 18 and 19. Twenty connecting rods 22 are inserted, and the male screw portion 14 of the connecting rod 22 is screwed into the female screw portion 14 of the mounting plate 12.

  Therefore, the upper plate 20 and the mounting plate 12 are connected by the connecting rod 22 so that the operator can get on the upper surface of the floor base material 2 stably by sandwiching the floor base material 2 from above and below. It will have strength. The floor base material 2 is supported by the four support legs 3, but the number is not limited to four, and can be supported by more or less support legs 3.

FIG. 4 shows a floor structure 23 according to the second embodiment. The floor structure 23 is a double floor in which the finishing material 6 is laid on the lower floor 5 via the vibration control surface material 24. The floor structure of the first embodiment except that the vibration control surface material 24 is laid. 1 is the same configuration. The seismic damping surface material 24 enhances the lightweight floor impact sound insulation performance, and an absorbing material that absorbs vibration is used in addition to an asphalt sheet or a rubber sheet having a surface density of 9 kg / m ² or more.

  Next, the construction method of the floor structure will be described based on the floor structure 1 of the first embodiment. First, as shown in FIG. 5, the support legs 3 are installed on the upper surface of the slab 4 at an appropriate interval. The support leg 3 is simply installed on the upper surface of the slab, or is fixed to the upper surface of the slab by applying an adhesive to the fixing plate 11. Moreover, the mounting plate 12 of the support leg 3 can move up and down the column base 10 by rotating.

  Next, as shown in FIG. 6, the floor base material 2 is installed on the support leg 3. Flat circular installation grooves 18 and 19 are formed on the upper and lower surfaces of the floor base material 2. When the floor base material 2 is installed by fitting the mounting plate 12 into the installation concave grooves 19 on the lower surface, The through hole 21 between the installation grooves 18 and 19 of the floor base material 2 matches the hexagon socket nut 16 of the mounting plate 12. Therefore, the mounting plate can be rotated by inserting the operating rod into the hexagon socket nut 16 from the upper surface of the floor base material.

  Next, as shown in FIG. 7, the hexagon wrench 17 is inserted from the through hole 21 of the installation groove 18 on the upper surface of the floor base material 2, and the tip thereof is inserted into the hexagon socket nut 16 of the mounting plate. And the horizontal level of the floor base material 2 is adjusted by adjusting the unevenness of the slab 4 by rotating the mounting plate 12 with the hexagon wrench 17 and moving it up and down.

  This is performed by using the upper surface 25 of the joist as the reference surface, and the upper surface 25 and the upper surface 26 of the floor base material are made to coincide. After this level adjustment is completed, the mounting plate 12 is fixed by filling the female screw portion 14 with the adhesive from the hexagon socket nut 16 of the mounting plate.
