[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel fixing device for fixing a floor panel to a support mechanism.

[0002]

2. Description of the Related Art In a clean room for a semiconductor manufacturing plant or a large computer, a double floor in which grating, which is a kind of floor panel, is laid on a support mechanism such as a floor frame for the purpose of air conditioning or the like. I have. In this double floor, the fixture fixes the grating to the floor frame, and further fixes semiconductor manufacturing equipment, computers and other devices to the grating. This prevents the equipment from falling when an earthquake occurs. In particular, in recent years, there has been an increasing trend to prevent damage caused by the earthquake, and even in an existing clean room where the above-mentioned fixation has not been performed at the time of construction, renovation work for fixing the floor frame and the grating has been promoted.

A conventional method of fixing grating to a floor frame will be described with reference to FIG. A lower pedestal 51, a support 52, and an upper pedestal 53 are placed on a floor base G such as concrete.
A large number of supporting legs 5 are installed at predetermined intervals. A bar-shaped floor frame 4 is bridged on the support legs 5 and fixed to the support legs 5. FIG. 6 shows only the end face of the floor frame 4, but the floor frame 4 extends in the left-right direction and the direction perpendicular to the paper of the drawing, that is, is stretched in a lattice shape. Grating 6 on this floor frame 4
Is laid. In FIG. 6, the ends of the two left and right gratings 6, 6 are placed on one floor frame 4.
An annular washer 82 is placed on the ends of the gratings 6, 6, and a set screw 81 is inserted downward from the center of the washer 82. The set screw 81 passes through the gap between the gratings 6 and 6 and is screwed into the lower floor frame 4. The grating 6 is fixed to the floor frame 4 by the washer 82 and the set screw 81.

In this conventional fixing method, the upper surface of the washer 82 is located higher than the upper surface of the grating 6.
Therefore, there is a danger that the worker may trip on the washer 82. Further, in order to prevent the device from tilting, the device cannot be installed on the washer 82. Further, even if the existing clean room in which the equipment is already installed is remodeled to fix the grating 6 near the foot of the equipment, the washer may hinder the installation of the washer 82 in some cases. In addition, when the fixed grating 6 is peeled off for the purpose of maintenance or the like, it is necessary to remove the set screw 81 with a tool each time, and there is a problem that much labor is required.

The fixing between the floor panel and the support mechanism is released by releasing the locking of the locking member and the holding member, and the gap is provided between adjacent floor panels, or provided on the floor panel. The holding member is provided with an upper surface of a base portion that is in contact with the bottom surface of the main body of the latch member, and a cutout portion cut out downward from the upper surface of the base portion. Before The latching member includes the stopper, a main body, and a hook portion that hangs down from one end of the main body and is fitted into a notch of the holding member. The stopper locks when an upward load is applied to the stopper. It is attached to the other end of the main body so that a rotational moment is generated in the member, and when the rotational moment is generated, the rotation of the latch member is caused by the contact point between the surface of the hook and the surface of the notch. The floor panel fixing device is characterized in that the fixing member is prevented from rising, the lifting member is prevented from rising, and the locking member is locked on the holding member.

Since the floor panel fixing device of the present invention is used by being disposed in a gap between adjacent floor panels or in an opening provided in the floor panel, the upper surface of the floor panel fixing device is higher than the upper surface of the floor panel. Almost never located. Therefore, it is possible for the operator to install the apparatus on the floor panel fixture without the operator tripping. In addition, since it does not have the washer of the conventional example shown in FIG. 6, it can be applied to a floor panel near a leg of an existing device. In addition, the floor panel is fixed to the support mechanism by the hook member and the hold member being hooked on the hold member, and the hook between the hook member and the hold member is released. As a result, the fixing between the floor panel and the support mechanism is released, so that the floor panel can be easily peeled off as necessary while realizing the secure fixing between the floor panel and the support mechanism.

FIG. 1B shows the holding member 3. The holding member 3 mainly includes a base portion 31,
It comprises a flange 32 and a notch 33. The base portion upper surface 34 is a portion that comes into contact with the main body bottom surface 25 of the hook member 2 when the hook member 2 and the hold member 3 are hooked. The flange portions 32 are provided below both sides of the base portion 31. A screw hole 35 is provided in each of the flange portions 32, 32, and the holding member 3 is fixed to the floor frame 4 by a screw 36 penetrating the screw hole 35 as described later.
To be fixed. The hook portion 22 of the hook member 2 is fitted into the notch 33 when the hook member 2 and the hold member 3 are hooked. The portion shown by the solid line in FIG. The holding member 3 may be integrally formed by cutting out a metal plate, or may be formed by forming the base portion 31 and the flange portion 32 as separate members and then joining them by welding or the like. .

FIG. 2A shows a state in which the hook member 2 and the hold member 3 are hooked. The main body bottom surface 25 of the hook member 2 is in contact with the base portion upper surface 34 of the hold member 3. The hook portion 22 of the hooking member 2 is fitted in the notch 33 of the holding member 3. In this state, the stopper 23 is engaged with the engaging portion of the outer frame 63 of the grating 6 as described later. When the grating 6 is to be peeled upward due to an earthquake, an upward load is applied to the stopper 23 via the engaging portion of the grating 6. The stopper 23 is connected to the main body 2 as described above.
1 is provided near the second end. Therefore, when an upward load is applied to the stopper 23, a rotational moment in the direction indicated by the arrow M is generated in the latch member 2 itself,
The latch member 2 is about to rotate. However, the hook part 22
Abutment between the surface of the notch 33 and the surface of the notch 33 (indicated by dotted circles P and Q in the figure) prevents this rotation, and as a result, the stopper 23 is prevented from rising. Therefore, the upward movement of the grating 6 is prevented, and the grating 6 does not come off. The hook 22 and the notch 33
Preferably, as shown in FIG. 2A, the contact portion P is formed in a so-called undercut shape. As a result, the lifting of the locking member 2 when an upward load is applied to the stopper 23 is more reliably prevented.

FIG. 2B shows a state in which the locking between the locking member 2 and the holding member 3 is released. As described above, the main body bottom surface 25 near the second end is provided with the inclined portion 24 that rises to the left in the figure, and a gap K is generated between the inclined portion 24 and the base portion upper surface 34 of the holding member 3. ing. When the locking of the locking member 2 and the holding member 3 is released, the second end of the main body 21 of the locking member 2 is pressed downward, and the gap K is narrowed. As a result, the hook member 2 rotates in the direction indicated by the arrow N, and the hook 22 is pulled out of the notch 33. In this way, the locking between the locking member 2 and the holding member 3 is released, and the grating 6 can be peeled off. That is, the floor panel fixing device 1 can release the fixing between the grating 6 and the floor frame 4 with a so-called one-touch operation.

Next, a method of fixing the grating 6 using the main floor panel fixing device 1 will be described with reference to FIGS. FIG. 3A is a plan view showing a state in which the floor panel fixture 1 is installed between the gratings 6, 6, and FIG. 3B is along a line AA in FIG. 3A. FIG. 4 is a front view of FIG. 3A. However,
