A rotary tightening means 9 is provided, which is disposed in the gap 2 and connects the upper and lower pressing pieces 7 and 8, and is erected upward at one end of the lower pressing piece 8. A rotation stopper 10 is provided in contact with the lower inner surface of the frame member 6.

In Fig. 1, a foundation 1 is made of concrete or the like. As in the conventional example shown in FIG. 6, the floor panels 3 and 4 are fixed with their four corners resting on base hardware (not shown) installed on the foundation 1. floor panels 3, 4
consists of frame members 5 and 6 and top surface members 3b and 4b. The frame members 5 and 6 are inward channel-shaped members made of iron or the like and forming four sides of a rectangle. Surface material 3b, 4b
are attached to the upper surfaces of the frame members 5 and 6. The rising portions of the frame members 5 and 6 are located outside the end surfaces of the surface members 3 and 4. The gap 2 is formed by these frame materials 5,
This is the space between the rising parts of 6.

The upper holding piece 7 is a rectangular flat plate made of iron or the like,
It has a bolt insertion hole in the center. The width of the upper pressing piece 7 is narrower than the width of the gap between the surface material 3b and the surface material 4b. The lower stopper piece 8 is a rectangular flat plate made of iron or the like, has a rotation stopper 10 at one end, and has a bolt insertion hole closer to the other end than the center. The width of the lower pressing piece 8 is narrower than the gap between the frame members 5 and 6.

The rotational tightening means 9 includes a bolt 11 and a nut 1.
Consists of 2. The bolt 11 is a long bolt that is inserted through each bolt insertion hole of the upper holding piece 7 and the lower holding piece 8. The head of the bolt 11 is located above the upper holding piece 7. The nut 12 is projection welded to the lower surface of the bolt insertion hole portion of the lower holding piece 8, and is threadedly engaged with the bolt 11. Rotation stop part 1
0 consists of the head of a bolt screwed into the upper surface of the lower holding piece 8 up to the lower part of the neck.

The procedure for connecting the floor panels of this embodiment will be explained. First, as shown in FIG. 2, with the upper holding piece 7, the lower holding piece 8 and the rotary tightening means 9 temporarily tightened, the floor panels 3 and 4 are arranged in parallel in the width direction of the lower holding piece 8. Insert the lower pressing piece 8 along the gap below the frame members 5 and 6. Then, rotate the lower stopper piece 8 there, and rotate the rotation stopper 10.
is brought into contact with the lower side surface of the frame member 6. The bolt 11 constituting the rotational tightening means 9 is arranged so that the upper holding piece 7 spans both upper surfaces of the frame members 5 and 6.
Tighten it against the nut 12 to secure it completely.

As described above, according to this embodiment, the upper holding piece 7 holds down both upper surfaces of the pair of frame members 5 and 6 that constitute the adjacent ends 3a and 4a of the floor panels 3 and 4 arranged side by side. A lower pressing piece 8 is provided which holds down both lower surfaces.
Since the rotary tightening means 9 is provided to connect the upper holding piece 7 and the lower holding piece 8, the adjacent ends 3a and 4a of the floor panels 3 and 4 arranged in parallel are connected to the rotating tightening means 9. Tightened upper holding piece 7
and the lower pressing piece 8, and are fixed at the same height. Therefore, even if heavy items such as furniture are installed on the top surface of the floor panels 3 and 4, the floor panels 3 and 4
It is possible to prevent the occurrence of uneven ground between each other.

Further, a rotation stopper 10 is provided upwardly at one end of the lower stopper piece 8 and abuts against the inner surface of the lower part of the frame member 6.
, the lower pressing piece 8 does not rotate even if the rotary tightening means 9 is rotated. Therefore, the position of the lower pressing piece 8 does not shift, making the work easier.

Further, the length of the upper holding piece 7 in the connection direction needs to be set larger than the gap between the frame members 3a, 4a and smaller than the gap between the surface members 3b, 4b. On the other hand, depending on the type and installation condition of the floor panels 3 and 4, there may be variations in the gap between the surface materials 3b and 4b and the gap between the frame materials 3a and 4a, making it impossible to attach the upper holding piece 7. There are cases. In such a case, by changing the orientation of the upper holding piece 7, it is possible to accommodate variations within the length range of the two adjacent sides. For example, the surface material 3b
If the design dimension of the gap between the upper holding piece 7 and the surface material 4b is 50 mm, the length of the two sides of the upper holding piece 7 is, for example, 48 mm.
If you set mm and 52mm, surface material 3b and surface material 4b
It can accommodate variations in the gap size between the two.

The upper holding piece 13 shown in FIG. 3 has locking portions 13a projecting downward at four corners. The upper stopper piece 14 shown in FIG. 4 has locking portions 14a bent downward on two opposing sides.

According to this embodiment, the same effects as the embodiment shown in FIG. 1 can be obtained. Further, as shown in FIG. 5, the locking portions 13a and 14a increase the surface pressure on the upper surfaces of the frame members 5 and 6, so that there is an effect that the frame members are hard to slip and can be securely fixed. In FIG. 5, the components other than the upper pressing pieces 13 and 14 are the same as those in the embodiment shown in FIG. 1, so the same reference numerals are given to the figure and the explanation will be omitted.

The nut 12 may not be provided, and a screw hole may be provided in the lower pressing piece 8. In this case, the rotational tightening means 9
are the bolt 11 and the screw hole.

The bolt 11 may have threaded portions at both ends, and the upper end may be screwed into a nut above the upper holding piece 7. In this case, the rotary tightening means 9 are the bolt 11, the nut and the nut 12.

The rotation stopper 10 may be constructed by bending one end of the lower stopper piece 8 upward.
