Features.

(Function) According to the floor panel support device of the present invention having such a configuration, a slide ring formed of a self-lubricating synthetic resin such as nylon is interposed between the panel holder and the floor panel, Since the frictional force between them is reduced, press the panel, insert it into the through hole formed by laying all the floor panels, and then perform a rotation operation to fix the tear 07 paul in a press-contact manner. Even when the panel holder is rotated, the panel holder can be rotated smoothly, improving work efficiency. Furthermore, the structure has no metal contact between the panel holder and the floor panel, which prevents damage to the contact surfaces between them.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

The free access floor 1 consists of a floor and Avanel support system #t20 whose main components are fixed legs 4 erected on a reference floor surface 3 and stringers 15 installed between the adjacent fixed legs 4.4. It is constructed by placing and fixing a plurality of floor panels 2 on.

The fixed legs 4 are attached to corner portions 2 of four adjacent floor panels 2 in the center of the free access 70a1.
It is arranged below the position where four corner parts 2a of two mutually adjacent floor panels 2 come together in the wall side part of the free access floor 1, and it is arranged below the position where two corner parts 2a of two mutually adjacent floor panels 2 come together. has been done.

The fixed leg 4 is connected to a cylindrical column with a stringer support 8 at its upper end via a height adjustment mechanism 6 at the center of the upper surface of a base 5 fixed at a predetermined position on the reference floor surface 3. It is constructed by erecting legs 7. The stand 8 of this stringer receiver has four grooves 8a for accommodating the ends of the stringer 15, and these grooves 8a are formed in a cross shape and project horizontally. Furthermore, the stringer 15 is formed by bending into a channel material having a U-shaped transverse cross section, and the upper surface of the end portion of the stringer 15 has a surface 15a on which the seven rung portions 2d of the floor panel 2 abut. , stringer-15
After molding, it is formed by pressing with high precision in height and flatness.

The floor panel 2 is formed into a substantially square shape, and an upper surface panel 11 and a lower surface panel 12 are overlapped and integrated in a hollow shape, and an inorganic filler is filled and sealed in the hollow portion. A quadrant-shaped step portion 2b is provided at each corner portion 2a, and seven rung portions 2c are formed at the edge.

The panel retainer lO is composed of a cylindrical shaft portion 10a and an overhanging retaining portion 10b provided at the upper end of the shaft portion 10a. Fixed. The panel presser 9 that engages with the panel presser receiver 10 and fixes the floor panel 2 is formed into a hollow columnar shape, and has seven rungs 9a at the top and an insertion hole 9b in the center. , engagement stepped portion 9
