Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a floor plate support used for constructing a double floor for OA cable wiring.

[Background technology]

For example, in a double-floor structure in which floorboards are laid out on a concrete floor at regular intervals, there is a type of support shown in FIG. 4 that supports the floorboards.

This support includes an adjustment support shaft 1 erected on a base 2, a seat piece 3 screwed onto the upper part of the adjustment support shaft 1, and a tightening napft 4 provided on the adjustment support shaft 1. It is being When placing the support on the floor 8,
With the tightening nut 4 loosened, the seat piece 3 is moved up and down along the adjustment support shaft 1 to a predetermined height, and then the tightening nut 4 is tightened.

However, in the support, the tightening nut 4 is located below the seat piece 3, so in order to easily tighten the tightening with sufficient space, the tightening nut 4 must be adjusted and supported. It is necessary to place it considerably above the axis 1 rather than at the bottom. Due to the need for this upper placement, the overall height of the support must be increased.

Dimensionally high supports are suitable for use in computer rooms, for example, when a large air-conditioning space of about 300 to 500 mm is required between the floor surface 8 and the floor plate F, but when a low and small space is required, e.g. For OA office use,
It was inappropriate. In this case, it is structurally possible to make the tightening napft 4 sufficiently low, but if it is set too low, a large working space for the tightening cannot be secured.
There is an inconvenience that makes construction difficult, so 100mm is inevitable.
The limit was a height of J degree.

[Purpose of the invention]

The present invention was made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a floor plate support that is easy to construct and can provide a low floor height.

[Disclosure of the invention]

In order to achieve the above object, the floor plate support according to the present invention includes a base, an adjustment support shaft having a threaded portion formed on the outer periphery and erected on one side of the base, a bottom plate portion and an adjustment support shaft rising from the outer periphery thereof. A catch piece that is provided with a rising part and a receiving flange formed at the upper end of the rising part, is shaped like a saucer with an upwardly opening center, and is screwed onto the adjustment support shaft via a threaded part provided at the bottom of the saucer piece. and a tightening bolt which is threadedly engaged with the adjustment support shaft within the seat piece.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings showing embodiments thereof.

FIG. 1 shows the floorboard support according to the present invention disassembled, and FIGS. 2(a), (b), and tc+ show details of its assembled state. As shown in the figure, this floorboard support comprises a base 2. having an adjustable support shaft 1. Prisoner Peace 3
．． It consists of a tightening nut 4 and a cushion rubber 5.

The adjustment support shaft 1 has a threaded portion 6 on its outer periphery, and is erected by welding at the center of the base 2. Base 2 is
As shown in FIG. 2(C), it is a square plate made of a metal plate, and a plurality of fixing through holes 7 are arranged on its surface. This base 2 is placed on a concrete floor surface 8 and fixed with fixtures 9 such as concrete nails or anchor bolts, as indicated by two-dot chain lines in FIG. 2(a).

The seat piece 3 is a drawn product that integrally includes a bottom plate portion 10, a rising portion 11, and a receiving flange 12, and is also made of a metal material. The bottom plate part 10 is disk-shaped, and as shown in FIG. The receiving flange 12 has a cylindrical shape rising upward from the outer periphery, and has a recess 14 formed inside it and an opening 15 formed at its upper end.
extends in the outer diameter direction from the upper end of the rising portion 11,
When viewed from above, it forms a ring shape. Bottom plate part 1 of catch piece 3
A square NAND-shaped screw piece 17 is fixed to the center of the lower surface by a joint part 16, and is screwed to the adjustment support shaft 1 via a screw part 18 formed through the center thereof.

The tightening nut 4 is made of a hexagonal nut and is positioned within the recess 14 and screwed onto the adjustment support shaft 1. The cushion rubber 5 is provided for the purpose of absorbing the difference in level between the floorboards F and suppressing walking noise, and is formed into an annular shape with an L-shaped cross section so as to fit the upper surface and outer peripheral edge of the receiving flange 12. A through hole 19 is formed in the center, and four low cylindrical engaging protrusions 20 are arranged at equal intervals in the circumferential direction on the upper surface. On the upper side of this cushion rubber 5, as shown in FIG. 3(a), a part of the corner of the floorboards F arranged adjacent to each other is placed.

In this case, as shown in FIG. 3(b), one engagement hole 21 that opens downward is formed in a part of each corner of the floor plate F, and in each engagement hole 21, The engaging protrusions 20 that protrude upward are engaged with the surface of the cushion rubber 5 with a slight gap left around the circumference, allowing the floor plate F to move slightly, while the elasticity of the engaging protrusions 20 allows for large movements of the floor plate F. It is designed to effectively prevent misalignment by providing a buffering effect.

As shown in FIG. 2(a), the floor plate support includes a base 2 on which an adjustment support shaft 1 is erected, a saucer-shaped receiving piece 3 provided with a receiving flange 12 and a threaded portion 18, and a receiving plate. It has a tightening nut 4 fitted in the recess 14 of the seat piece 3 and fitted with the adjustment support shaft 1, and as shown in FIG. 3(a), for example, when four floorboards F are butted These floorboard supports are arranged with their centers aligned with the locations corresponding to the locations where they will be installed, and as shown in FIG. The height is adjusted according to the specified height h to the top surface of the rubber 5. This height adjustment is performed by rotating the catch piece 3 and moving the screw piece 17 up and down along the adjustment support shaft 1. After the height setting is finished, tighten the tightening nut 4. As a result, the catch piece 3 is locked.

After that, the cushion rubber 5 is fitted onto the upper surface of the seat piece 3, and as shown in FIG. Orient the cushion rubber 5.
Floorboard F is placed on top and construction is completed.

In the floor plate support, the tightening napft 4 is connected to the seat piece 3.
It is arranged not on the underside but in the recess 14 of the seat piece 3, and as shown in Fig. 2(a), it can be tightened from above with a tightening tool 22 such as a socket wrench. , there is no space disadvantage associated with tightening at the bottom, unlike in the past.
Tightening work can now be carried out using the wide upper space. This tightening can be performed in exactly the same way even when the seat piece 3 is lowered to its limit, and therefore it becomes possible to set the seat piece 3 sufficiently lowered to its limit. In this way, it is possible to provide a floorboard support with a height h by sufficiently lowering the height, so for example, in the embodiment, the underfloor height h can be suppressed to about 55 mm or less, and the floor height can be made sufficiently low. OA with request to configure
It is now possible to implement it for office use without any construction restrictions. Furthermore, since the tightening nut 4 is arranged above the seat piece 3, the seat piece 3 can be lowered until it approaches the base 2, and the height adjustment range is expanded accordingly.

In the embodiment described above, the threaded piece 17 is provided separately, but the threaded part 18 can also be provided directly on the bottom plate part 10 of the seat piece 3. Although the seat piece 3 is an integral type, it is also possible to separate each part and form one seat piece 3 by welding. Although the receiving flange 12 is said to extend only in the outer diameter direction, it extends only in the inner diameter direction.
Alternatively, it may extend in both the inner and outer diameter directions.

〔Effect of the invention〕

As is clear from the above description, the floor plate support according to the present invention includes a base, an adjustment support shaft having a threaded portion formed on the outer periphery and erected on one side of the base, a bottom plate portion and the outer periphery thereof. A receiving seat comprising a rising portion and a receiving flange formed at the upper end of the rising portion and having a saucer shape with an upwardly opening center and screwed onto the adjustment support shaft via a threaded portion provided at the bottom thereof. Since the floor plate support has a piece and a tightening napft that is threadedly engaged with the adjustment support shaft within the seat piece, it is easy to construct and can provide a low floor height.
