Description

Description: TECHNICAL FIELD The present invention relates to a fixing metal fitting used for a floor-standing floor panel.

(Prior art) A floor panel is laid on a standard floor surface such as a concrete floor via supporting legs, and a free space is secured between the floor panel and the standard floor surface so that cables and ventilation ducts can be arranged. Heavy floor structures, or free access floors, are known.

Here, a floor-standing type floor panel, that is, the floor panel provided with support legs is placed on the reference floor surface, in order to prevent the horizontal movement of the floor panel,
Use the connecting members to connect the floor panels to each other to prevent backlash and lateral slippage, or install a fixing bracket A as shown in FIG. 5 on the lower surface of the support legs of the floor panel to reinforce the support legs. I was going.

(Problems to be Solved by the Invention) In order to prevent the relative movement of the floor panel and the reference floor surface, it was necessary to hold the support leg by a fixing bracket or the like fixed on the reference floor surface. When the fixing metal fitting A is used, the lower end of the support leg D of the floor panel C is fitted into the hole B formed in the upper surface thereof from above. For this reason, at the time of construction, it is necessary to fix the fixing metal fitting A in advance to a predetermined position that has been marked out, or to raise the floor panel C once laid to perform positioning and fixing of the fixing metal fitting A. There was a problem that became complicated.

The present invention provides a fixing bracket for a floor panel that can be easily positioned and fixed while laying the floor panel without requiring positioning work such as marking out when constructing a floor-standing type floor panel. Is intended.

(Means for Solving the Problems) In order to achieve the above object, a fixing bracket for a floor panel according to the present invention is a floor for simultaneously fixing support legs of respective floor panels at a position where corner portions of a plurality of floor panels are gathered. A structural feature of the fixing member of the panel is that a slit with which the support leg is engaged is formed so that one end thereof is opened to a peripheral edge portion.

(Function) When constructing a free access floor, lay a floor panel to a predetermined position, then engage the slits of the fixing brackets with the supporting legs of the two adjacent floor panels to position the fixing bracket. To do. Then, the fixing metal fittings can be fixed to the reference floor surface in the laid state of the floor panel.

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

The floor panel 2 is connected by the connecting member 1 and is fixed by engaging the supporting leg 6 with the slit 9 of the fixing fitting 8 fixed on the reference floor surface 10.

In this connecting member 1, a plurality of flange portions 1b are formed on an upper portion of a cylindrical body portion 1a, and on the other hand, a plurality of leg portions 1c are integrally provided on the lower portion at intervals of 90 ° so as to project outward. A rising portion 1d is formed at the top end of the leg portion 1c. The upper surface is provided with an insertion hole 1e into which a tool such as a screwdriver for rotating the connecting member 1 is inserted.

The floor panel 2 is formed in a substantially square shape, and an upper surface panel 3 and a rear surface panel 4 are overlapped with each other in a hollow shape so as to be integrated, and an inorganic filler 5 such as mortar is filled and sealed in the hollow portion. . A step portion 2b is formed on the corner portion 2a of the floor panel 2, and a locking groove 2c is provided on the back surface. Further, a support leg 6 is provided slightly inward of the corner portion 2a, and a screw portion 6a is formed on the outer peripheral surface of the support leg 6 and a screw portion 7a of a screw hole member 7 press-fitted and fixed to the floor panel 2. It is screwed and hung vertically so that it can move up and down.

Further, the fixing member 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 having a slightly enlarged opening 9a, and the periphery thereof is raised in a U-shaped cross section. Since these opening directions are different from each other, if the floor panel 2 is connected by the connecting member 1, even if a force acts in a certain opening direction, the other three supporting legs 6 receive the force. Therefore, the occurrence of displacement is prevented. Further, a hole 8a is formed for raising the adhesive to prevent it from shifting, and the fixing metal fitting 8 is fixed to the reference floor surface 10 by this adhesive. In addition, 8b in the figure shows a notch when it is aligned with the marking line.

Here, the connecting and fixing state of the floor panel 2 will be described. The flange portion 1b of the connecting member 1 is engaged with the step portion 2b of the floor panel 2, and the upper surface of the leg portion 1c abuts on the rear surface of the floor panel 2. In addition, the rising portion 1d has a locking groove 2e
Is engaged with. At this time, the connecting member 1 has the flange portion 1b.
The tightening force is increased by the elastic force caused by the elastic deformation of the leg portion 1c. By such a connection, occurrence of a jack knife phenomenon or the like when a horizontal load is applied is suppressed.

On the other hand, the supporting legs 6 of these floor panels 2 are held at the innermost portions 9b of the slits 9 of the fixing metal fittings 8 at appropriate positions to prevent the floor panels 2 from moving in the horizontal direction.

Now, a method of constructing a free access floor will be described with reference to the drawings. First, the floor panels 2 are sequentially laid, and when the floor panel 2 to which the fixing metal fitting 8 is attached is laid, one of the slits 9 of the fixing metal fitting 8 is engaged with one of the support legs 6, Rotate the fixing bracket 9 using the support leg 6 as a fulcrum to move the other slit 9 and the support leg 6
And (see FIGS. 4 (a) (b) (c)). As a result, the fixing metal fitting 8 is positioned, so that the fixing metal fitting 8
Is fixed to the reference floor surface 10 with an adhesive or the like. Since the fixing panel 8 is integrated with the floor panel 2 by the connecting member 1, it is not necessary to provide it on all of the supporting legs 6, and it is necessary to consider the size of the floor, or a certain section where it is desired to prevent displacement. Is arranged.

In parallel with this work, the connecting member 1 is inserted into the through hole 12 formed by assembling the four floor panels 2, and the insertion hole 1e is inserted.
Insert the screwdriver into and rotate the floor panel 2 by rotating it by a predetermined angle (about 45 °). The height of the floor panel 2 is adjusted by inserting a driver into the insertion groove 6b on the upper surface of the support leg 6 and rotating the support leg 6. Incidentally, a cut panel 11 is appropriately laid on the wall surface side.

(Effect of the Invention) As described above, according to the fixing bracket of the floor panel of the present invention, while laying the floor panel, the fixing bracket is positioned at any time by engaging the slit with the supporting leg of the floor panel. Further, since the fixing bracket can be fixed to the reference floor surface while the floor panel is laid, the workability is very good.
