Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a height adjusting device for a floor plate or the like. For more information, OA
In order to install cables for various electric devices under the floor, such as in the equipment room, when laying floor plates at a specified interval from the existing floor to construct an upper floor, embed it in the floor plate and adjust its height. The present invention relates to a height adjusting device for a floor plate or the like that can be performed.

[Conventional technology]

Like the OA equipment room, various electric equipment are installed, and more floor boards are laid at predetermined intervals on the existing floor of the building in order to store cables for connecting these equipment to each other and to the power supply etc. The upper floors are arranged side by side, and the above cables are delivered under the floor of this upper floor to prevent damage to the cables and to
I try to organize the equipment room. It is necessary to adjust the height of the floor board above the existing floor and to lay it horizontally and in a line.
Conventionally, as a height adjusting device for this kind of floor plate, four screw holes are formed at equal intervals along the periphery of the pedestal on the lower surface of the pedestal having an appropriate thickness, and a flange for placing the floor plate is provided on the outer periphery. The present applicant has provided a screw rod which is detachably screwed into each of the above-mentioned screw holes and has a floor plate placed on the above-mentioned collar (Showa 60 utility model registration application No. 54056). reference).

[Problems to be Solved by the Invention] In the above-mentioned conventional technique, the corners of four floor plates can be placed, and the height can be adjusted for each floor plate, but the screw rod is not provided. There is a problem that the floor may be stepped because it may be easily rotated.

The present invention has been devised in view of the above-mentioned problems, and after the height adjustment screw rod is set to a predetermined height, the screw rod is inadvertently rotated. The present invention provides a height adjusting device for a floor plate or the like that prevents the above-mentioned problem and keeps the floor surface horizontal and flush.

[Means for Solving the Problems]

In the height adjusting device for a floor plate or the like according to the present invention, a bendable plate-like body is provided on the lower surface of a pedestal having an appropriate thickness with a space between the pedestal and the pedestal. A screw hole communicating from the pedestal to the plate-shaped body is formed, and a screw rod for height adjustment is screwed into the screw hole. Further, it is characterized in that the lower end portion of the tightening screw inserted from the pedestal toward the plate-shaped body is screwed into the plate-shaped body.

[Function of device]

The height adjusting device of the present invention is embedded in, for example, a floor plate used when constructing an upper floor. Then, the floor boards are laid out so that the lower end portions of the height adjusting screw rods are in contact with the existing floor, and the height with respect to the existing floor is adjusted by rotating the screw rods. After setting to a predetermined height, the tightening screw is rotated. Then, the plate-shaped member into which the tightening screw is screwed is pulled up and bent, and the screw hole of the plate-shaped member and the height adjusting screw rod screwed into the plate-shaped member are in a strong crimped state. , Prevent rotation of the screw rod.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view, and FIG. 2 is a sectional view when it is used for a floor board.

As shown in FIG. 1, a height adjusting device for a floor plate or the like according to the present invention is provided with a bendable plate-like body 2 on the lower surface of a pedestal 1 having an appropriate thickness with a distance from the pedestal 1. The pedestal 1 is made of metal or the like, has a substantially elliptical shape with the flange 3 protruding, and has a thickness equivalent to the thickness of the floor plate 4, as an example.
The plate-like body 2 is extremely thinner than the pedestal 1 and is integrally provided on the lower surface of the pedestal 1 so that the end portion side is pulled up, or
It is pushed down and bends. Above pedestal 1
To the plate-shaped body 2, and a screw hole 6 having the same diameter as the screw hole 5 in the plate-like body 2.
The screw holes 5 and 6 communicate with the lower surface of the plate-like body 2 from the upper surface of the pedestal 1. A screw rod 7 for height adjustment is screwed into these screw holes 5 and 6. The screw rod 7 can be rotated from the upper surface side of the pedestal 1. Further, a through hole 8 is formed in the pedestal 1 at a position apart from the screw hole 5 toward the plate-like body 2,
The plate-like body 2 directly below the through hole 8 is also provided with a screw hole 9, and the lower end portion of the tightening screw 10 inserted from the passage 8 of the pedestal 1 is connected to the plate-like body 2 through the screw hole. 9 is screwed.
The tightening screw 10 can be rotated from the upper surface side of the base 1.

For example, as shown in FIG. 2, the height adjusting device as described above is embedded in each corner of the floor plate 4 used for constructing the upper floor. In this case, the floor boards 4 are laid out so that the lower end of the height adjusting screw rod 7 is in contact with the existing floor 11, and the screw rod 7 is rotated from the upper surface side of the pedestal 1 to adjust the height of the existing floor 11. Adjust. After setting the predetermined height, the tightening screw 10 is rotated from the upper surface side of the pedestal 1 so that the plate-shaped body 2 is pulled up from the position of the dotted line to the position of the solid line and bent. Then, a slight deviation occurs between the crests and troughs of the screw holes 9 of the plate-shaped body 2 and the troughs and crests of the screw rods 7, and the screw holes 9 and the screw rods 7 are brought into a strong crimped state. Therefore, the rotation of the screw rod 7 is prevented. Further, since the tightening screw 10 is pulled downward by the plate-shaped body 2 in the bent state, it does not rotate carelessly.

The case where the present invention is used for the floor plate for the upper floor has been described, but it is needless to say that the present invention is not limited to this and can also be used for various office machinery and furniture, furniture, and the like.

[Effect of device]

As described above, according to the present invention, when the tightening screw is rotated to bend the plate-shaped body, the screw hole of the plate-shaped body and the height adjusting screw rod screwed into the plate-shaped body become strong. Since the screw rod does not inadvertently rotate due to a crimped state, the set height can be maintained. In addition, it has a wide range of uses such as floorboards for upper floors and various office machinery.
