On the other hand, with floor panels and support legs that are separate, height-adjustable support legs are used.
After fixing the support legs to the reference floor surface in advance, the corners of each floor panel are placed on the support legs, and by adjusting the height of one support leg, the corners of multiple floor panels can be adjusted. The height can be adjusted at the same time, requiring less adjustment work compared to a type with integrated support legs. However, height adjustment work had to be done below the floor panel, and the height was 100mm from the standard floor level.
In the case of a low-level free access floor of a certain height, the worker was forced to take an awkward posture of looking into the side of the supporting legs, which similarly caused problems with poor workability.

(Function) When constructing a free access floor, first, the base portions of the support legs are fixed below the location where a plurality of corner portions of the floor panels, which are laid at intervals from the reference floor surface, gather. Next, the corner of the floor panel is placed on the panel holder and the floor panel is laid. Then, when the adjustment leg member is rotated from above the floor panel while checking the installation condition of the entire floor panel, the adjustment leg member rotates in the vertical direction with respect to one threaded part of the support shaft of the base. Along with this movement, the panel holder also moves in the vertical direction, and the heights of the corners of the plurality of floor panels are adjusted simultaneously. After the floor panel is installed, the height of the corner of the floor panel can be adjusted by rotating the adjustment leg member from above the floor panel. When the height adjustment work is completed, the panel fixing member is passed through the adjustment leg member and screwed onto the other threaded part of the support shaft, and the panel fixing member presses the floor panel against the panel holder and fixes it. At the same time, a pressing force is applied from the panel holder to the adjusting leg member, and the pressing force presses the adjusting leg member against one threaded portion of the support shaft. This results in
There is no looseness between the adjusting leg member and one of the threaded parts, that is, looseness in the adjusting mechanism part.

Now, the method of constructing the raised floor 1 will be explained based on FIGS. 1 to 3. First, there are four or two corner parts 2a of the floor panel 2.
The base portion 6 is fixed at the individual assembly position using fixing means 5 consisting of bolts and nuts. Note that instead of the fixing means 5, an adhesive may be used for fixing.
Next, the adjustment leg member 8 is rotated about the threaded part 9a of the support shaft 9 to roughly adjust the height, and the corner part 2a of the floor panel 2 is placed on the mounting table 12 to lay the floor panel 2. do. At the time of laying the floor panel 2, while checking the installation state of the entire floor panel 2, insert a tool through the space 17 where the panel retainer 15 fits and the cylindrical part 13, engage it with the hexagonal engagement convex part 10, and insert the tool into the adjustment leg member. Rotate 8. As a result, the adjustment leg member 8 rotates relative to the threaded portion 9a of the support shaft 9 and moves in the vertical direction. At this time, the panel holder 7 also tries to rotate as the adjustment leg member 8 rotates, but since the rotation is prevented by the engagement between the protrusion 14 and the recess 2d, the panel holder 7 is adjusted without rotating. It moves only in the vertical direction along with the leg members 8. Note that when the adjusting leg member 8 rotates within the cylindrical portion 13, the anti-rotation convex portion 11a is once removed from the anti-rotation recess 13a, and then engages with the anti-rotation recess 13a again at the adjusted position.

The corner portions 2a of the two floor panels 2 can be moved up and down at the same time, reducing adjustment work to 1/4 compared to floor panels with integrated support legs, thereby significantly improving work efficiency. can be done. In addition, since the adjustment work is done from above the floor panel 2, you are not forced to take an unreasonable posture unlike when adjusting from below the floor panel 2, which improves work efficiency. Since adjustment work can be done while closely observing the installation condition of item 2, it can be done accurately.

After adjusting the height as described above, the corner portion 2a of the floor panel 2 is fixed onto the mounting table 12 using the panel presser 15 and the headed bolt 16.
At this time, since the headed bolt 16 is fixed by passing through the adjustment leg member 8 and tightening it into the threaded part (screw hole) 9b of the support shaft 9, the headed bolt 16 is connected to the floor panel 2. A pressing force in the direction of arrow A shown in FIG. 3 acts on the adjusting leg member 8 via the panel holder 7, and the pressing force presses the adjusting leg member 8 against one threaded portion 9a of the support shaft 9. . This eliminates play between the threaded groove 8a of the adjusting leg member 8 and the threaded portion 9a of the support shaft 9.

Conventionally, when a screw mechanism is used for the height adjustment mechanism, there is play in the adjustment mechanism, which causes the adjustment mechanism to tilt due to unbalanced loads, creating a step between floor panels, and horizontal loads caused by earthquakes, etc. When this was applied to the support leg 4, since the upper end was pin-coupled by the adjustment mechanism, a larger bending moment was applied to the lower end, and there was a risk that the support leg 4 would fall. In this embodiment, as described above, the play between the screw groove 8a of the adjustment leg member 8 and the screw portion 9a of the support shaft 9 is eliminated, and the floor panel 2 is fixed and integrated with the upper end of the support leg 4. This approximates a rigid rigid frame structure, so even if a horizontal load acts on the entire free access floor 1 due to an earthquake, a large bending moment (overturning moment) will not act on the lower end of the support legs 4, and the support There is no danger of leg 4 falling over.

In a raised floor type free access floor, the threaded part between the screw hole of the adjustment leg member 8 and the threaded part 9a of the support shaft 9 (the part where there is play, that is, the part where the pin is connected) is higher than the reference floor surface 3. Because of this position, the bending moment (overturning moment) that causes the substrate section 6 to separate from the reference floor surface 3 is greater than that of the low-floor type, and there is a high risk that the support legs 4 will overturn due to an earthquake or the like. However, when the headed bolt 16 is passed through the adjustment leg member 8 and screwed and tightened to the threaded portion 9b of the support shaft 9, the screw hole of the adjustment leg member 8 and the threaded portion 9a are tightened.
Since the floor panel 2 is fixed and integrated with the upper end of the support leg 4 to eliminate looseness in the threaded part between the support leg 4 and the support leg 4, even if horizontal loads such as earthquakes are applied, the support leg 4 will remain stable. A large bending moment (overturning moment) does not act on the lower end side, and there is no danger that the support leg 4 will overturn.

(Effects of the Invention) As explained above, according to the floor panel support device of the present invention, the height can be adjusted from above the floor panel at a position where a plurality of corners of the floor panel gather. Since the support legs are arranged, the height of the corners of multiple floor panels can be adjusted at the same time by adjusting the height of one support leg, and there is no need to force an unreasonable posture during this adjustment work. This makes it easy to perform height adjustment work during and after floor panel installation.

In addition, since the panel fixing member passes through the adjustment leg member and is screwed and tightened to the other threaded part of the support shaft of the base, play in the adjustment mechanism part can be eliminated and the upper end of the support leg 4 can be tightened. The floor panel 2 can be fixed and integrated into a rigid frame structure, and even if an uneven load is applied, the support legs 4 will not tilt and create a level difference in the floor panel 2, and the horizontal A large overturning moment does not act on the lower end side of the support leg due to the load, so there is no risk of the support leg overturning, and sufficient earthquake resistance is achieved.
