Abstract

PURPOSE:To enhance workability by fixing supporting legs, in the position where the corner parts of a plurality of floor panels are assembled, by means of a fixing device in which one end of each slit to the engaged with the supporting leg is opened at the peripheral part. CONSTITUTION:Floor panels 2 are connected by a connecting member 1, and also are fixed by engaging supporting legs 6 with the slits 9 of a fixing device 8 which has been fixed on a reference floor surface. Each floor panel 2 is formed nearly in a square shape, and the supporting leg 6 is erected in a slightly inner position of a corner part 2a to as to be movable in the up and down directions. And the fixing device 8 is square flat plate, and on each side thereof, a slit 9 having an opening 9a is provided, and the circumference thereof is raised in a U-shaped section, and further adhesive is filled up in holes 8a to fix it on the floor surface 10 (not shown). Thus, the need of positioning work of the fixing device 8 at the time of installation can be dispensed with, and positioning and fixing work can be carried out while the panels are being laid.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a fixing fitting used for a floor panel of a floor panel type.

(Prior technology) A floor panel is laid on a standard floor surface such as a concrete floor via support legs, and a free space is secured between the floor panel and the standard floor surface in which cables, ventilation ducts, etc. can be placed. Heavy floor structures, ie raised floors, are known.

A stand-alone floor panel, i.e., a 7a Abanel equipped with support legs, is placed on a reference floor surface, and in order to prevent the floor panel from moving in the horizontal direction, it is attached to the floor using a connecting member. The panels are connected to each other to prevent backlash and lateral displacement, or fixing fittings A as shown in FIG. 5 are installed on the underside of the support legs of the floor panel to reinforce the support legs.

(Problem to be Solved by the Invention) In order to prevent relative movement between the floor panel and the reference floor surface, it was necessary to hold the support legs with fixing fittings or the like fixed on the reference floor surface. When the fixture A is used, the lower end of the support leg of the floor panel C is fitted into the hole B formed in the upper surface of the fixture A from above. Therefore, during construction, it is necessary to either fix the fixing bracket A at a predetermined position marked out in advance, or to position and fix the fixing bracket A by lifting the floor panel C that has already been laid upwards. The problem was that it became complicated.

The present invention provides a floor panel fixing fitting that does not require positioning work such as marking when constructing a floor panel and can easily position and fix the floor panel while laying it. The purpose is to

(Means for Solving the Problems) In order to achieve the above object, the floor panel fixing fitting of the present invention provides a floor panel fixing fitting that simultaneously fixes the support legs of each floor panel at a location where the corner portions of a plurality of floor panels gather. A structural feature of the panel fixing fitting is that the slit in which the support leg is engaged is formed with one end thereof opening toward the peripheral edge.

(Function) When constructing a 7-lead access floor, the floor panels are laid down to a predetermined position, and then the slits of the fixing fittings are engaged with the support legs of two adjacent floor panels, respectively, and the fixing fittings are positioned. I do. The fixing fittings can be fixed to the reference floor surface while the floor panel is in this state.

(Example) An example of the present invention will be described below with reference to FIGS. 1 to 4.

The floor panels 2 are connected by the connecting members 1 and are fixed by the support legs 6 being engaged with the slits 9 of the fixing fittings 8 fixed on the reference floor surface 10.

This connecting member 1 has a plurality of 7
A rung portion 1b is formed, and on the other hand, a plurality of legs 1c are integrally provided outwardly projecting at 90° intervals at the lower part, and a rising portion 1d is formed at the top end of this leg IC. . Note that an insertion hole 1e into which a tool such as a screwdriver for rotating the connecting member 1 is inserted is provided on the top surface.

The floor panel 2 is formed into a roughly square shape, and the top panel 3 and the back panel 4 are overlapped and integrated into a hollow part, and an inorganic filler 5 such as mortar is filled and sealed in the hollow part. There is. A step portion 2b is formed at the corner portion 2a of the floor panel 2, and a locking groove 2C is formed on the back surface.
is provided. Further, a support leg 6 is provided slightly inwardly of the corner portion 2a, and a threaded portion '6a is formed on the outer circumferential surface of the support leg 6, and a threaded portion 7a of the screw hole member 7 press-fitted into the Avanel 2. It is screwed together and is installed vertically downward so that it can move up and down.

Further, the fixing fitting 8 is formed of a square flat plate, and is provided with a slit 9 having an opening 9a on each side. The slit 9 is formed in a U-shape with an opening 9a slightly enlarged, and the periphery thereof is raised to have a U-shaped cross section. Since these opening directions are different from each other, if the floor panels 2 are connected by the connecting members l, even if a force is applied in a certain opening direction, the force will be received by the other three support legs 6. Therefore, the occurrence of misalignment is prevented. Further, a hole 8a is formed for applying adhesive to prevent slipping, and the fixing fitting 8 is fixed to the reference floor surface 1O by this adhesive. Note that 8b in the figure indicates a notch when matching with the marking line.

Here, to explain the connected and fixed state of the floor panel 2, the seven rung portions 1b of the connecting member 1 are engaged with the stepped portions 2b of the floor panel 2, and the upper surface of the leg portion 1c is in contact with the back surface of the floor panel 2. Furthermore, the rising portion 1d is engaged with the locking groove 2e. At this time, the connecting member l is 7
The tightening force is increased due to the elastic force caused by the elastic deformation of the rung portion 1b and the leg portion 1c. Such a connection suppresses the occurrence of a jackknife phenomenon when a horizontal load is applied.

On the other hand, the support legs 6 of these 70 Avanels 2 are held in the innermost part 9b of the slit 9 of the fixing metal fitting 8 at appropriate positions, thereby preventing the floor panel 2 from moving in the horizontal direction.

Now, based on the drawings, we will explain how to construct a raised floor. First, the floor panels 2 are laid one after another, and when the floor panel 2 to which the fixture 8 is attached is laid, one of the slits 9 of the fixture 8 is engaged with one of the support legs 6, and this The fixing metal fitting 9 is rotated using the support leg 6 as a fulcrum, and the other slit 9 and the support leg 6 are engaged (see FIG. 4(a) (bXc)). This positions the fixture 8, so the fixture 8
is fixed to the reference floor surface lO with adhesive or the like. Since the floor panel 2 is integrated with the connecting member l, it is not necessary to provide the fixing fittings 8 on all of the support legs 6, and it is necessary to consider the width of the floor or a certain section where you want to prevent displacement. It will be arranged as follows.

In parallel with this operation, the connecting member l is inserted into the through hole 12 formed by the four floor panels 2 assembled together, and a screwdriver is inserted into the insertion hole 1e at a predetermined angle (approximately 45
) Rotate to connect the floor panels 2. Further, the height of the floor panel 2 is adjusted by inserting a screwdriver into the insertion groove 6b on the upper surface of the support leg 6 and rotating the support leg 6. In addition, for the wall side, cut panels 11 are installed as appropriate.

(Effects of the Invention) As explained above, according to the floor panel fixing fitting of the present invention, the fixing fitting can be positioned by engaging the slit with the support leg of the floor panel at any time while laying the floor panel. Furthermore, since the fixing fittings can be fixed to the reference floor surface while the floor panel is still installed, the workability is very good.
