Description

[Detailed description of the invention] [Industrial application field] This invention relates to double floors, and is particularly applicable to computer rooms and office automation equipment (hereinafter referred to as
The present invention relates to a floor panel suitable for use in a room (hereinafter referred to as an OA room) that uses a lot of OA equipment (OA equipment).

[Conventional technology]

The double-bed free access floors used in computer rooms and the like are mainly made of aluminum die-casting, but other types of flooring for general OA rooms include calcium silicate boards and glass fiber reinforced boards with zinc plating. There are some that are made of steel, but in most cases the floorboard and legs are separate members.
Many models have legs installed to adjust the height and level of the floor, and then the floorboards are placed on top of these legs. However, this type of floor is difficult to level and takes time to install.

Recently, in order to save these troubles, the four corners of the glass fiber reinforced cement (GRC) floorboard are integrally molded downward and protruded, nuts are embedded in these protrusions to fix them, and the leg bolts are screwed into these nuts. let me,
A system has been developed in which the height of the floor panel can be adjusted by rotating the leg bolts from above the floor panel.

However, with this floor panel, the dimensions of the floor plate and the position of the embedded nuts are fixed, so if there is an odd dimension at the end due to the effective dimensions of the room in which you are installing it, the Objects and supplementary construction to support them are required.

In addition, computers and OA equipment require a large number of wiring cables for power, input, output, etc., and in conventional floor panels, there is only one space at the bottom of the floorboard, so the above-mentioned Since a large number of cables all had to be accommodated in this one space, it was extremely troublesome to identify cables and carry them out by hand when moving computers and OA equipment or repairing malfunctions.

[Problem that the invention attempts to solve]

In order to improve the drawbacks of the above conventional technology,
No. 50-40951 proposes a hollow panel for floor construction in which the floor plate is an extrusion molded plate having hollow holes, and a floor adjustment fitting is attached to the back side of the extrusion molded plate.

However, this floor adjustment fitting is composed of a cylindrical part that has a female thread inside, a support plate fixed to the middle outer periphery of the cylindrical part, and a male threaded rod whose upper end is screwed into the female thread of the cylindrical part. It is a special metal fitting with a complex structure, and since there is no groove on the bottom of the floorboard, the support plate must be tightened to the floorboard with tightening bolts to prevent the support plate from rotating together due to the rotation of the male threaded rod. The problem was that it required a lot of effort and time-consuming work.

The present invention attempts to solve the above-mentioned problems in conventional floor panels.

[Means for solving problems]

In order to solve the above problems, the present invention provides a floor panel comprising the following (a) and (b).

(a) An extruded plate having a plurality of grooves on its lower surface and a plurality of hollow holes inside, which are perforated perpendicularly to the plate surface at the positions where the grooves are arranged, and a plurality of grooves are provided for each groove. Floorboards with perforations.

(b) a washer non-rotatably fitted and glued to the groove coaxially with the bore, a nut fixed to the washer coaxially with the washer, and a notch screwed onto the nut and provided at the upper end; Legs with screws.

It provides:

[Effect]

The present invention will be explained with reference to the drawings. Figure 1 is a plan view of an embodiment of the floor plate of the present invention, and Figure 2 is A-A in Figure 1.
A sectional view taken along arrow A, and FIG. 3 is a sectional view of an embodiment of the leg portion of the present invention.

The floorboard 1 is a hollow extruded board with multiple grooves 2 on the bottom surface.
and has a plurality of hollow holes 4 inside,
A plurality of perforations 8 are made for each groove at the positions where the grooves are provided, and a washer 7 is non-rotatably fitted into the groove at the position where the perforations are made and is adhered by a double-sided adhesive rubber plate 9. A nut 6 is fixed to the washer coaxially with the washer by welding, and a screw 5 having a notch 11 at the upper end is screwed into the nut, and a plurality of legs 3 that can adjust the floor plate up and down are fitted. They are then glued together to form the floor panel of the present invention.

That is, since the leg in the present invention is composed of a washer, a nut, and a screw, which are all common materials, there is no need for special metal fittings with a complicated structure as in the prior art.
Since the washer is non-rotatably fitted and glued into the groove in the floorboard, there is no need for the laborious work of tightening it to the floorboard with bolts as in the prior art.

The length, width, and thickness of the floorboard in the extrusion direction, as well as the shape and number of hollow holes 4, are not particularly limited. It will be decided after consideration. The number of grooves formed during the extrusion molding of the floorboard is not particularly limited as long as there are multiple grooves, and if there are two grooves, two legs are placed in each of these grooves on the floorboard. By fitting at intervals in the extrusion direction, the four legs can reliably support the floorboard at four points.

Since the grooves are extruded, any number of grooves can be easily provided.This increases the number of positions where the legs can be fitted and bonded in the width direction of the floorboard. Even if the legs are cut, the legs can be fitted and glued into appropriate grooves so that the width direction can always be supported by two legs. When supported by fitting and adhering, the deflection of the floorboard can be reduced more than when supported by two legs.

The molding position of the groove is not particularly limited either.
Even when the floorboard is cut in the width direction to match the dimensions with the installation surface, the floorboard is molded to a position where it can be stably supported by the legs.

The grooves are formed over the entire length of the floorboard in the extrusion direction, so even if the floorboard is cut to any length in the extrusion direction, the legs can be fitted and glued in appropriate positions to support the floorboard. can.

In other words, the floor panel of the present invention can always be supported by four or more legs even when cut in the extrusion direction or width direction in order to match the dimensions with the installation surface.
It can be laid over the entire surface without requiring additional equipment or supplementary work.

The grooves were provided to prevent the legs, which adjust the floorboard up and down by the rotation of built-in screws, from rotating together with the screws and making it impossible to adjust the floorboard up and down.For example, the legs shown in Figure 3 In section 3, the nut 6 that is screwed onto the screw 5 is fitted into the groove 2 and fixed to the non-rotatable washer 7 by welding. 8, even if a screwdriver or the like is inserted from above the floor into the notch 11 and the screw is rotated, the screw does not rotate together, and the floor plate can be adjusted up and down by rotating the screw.

Note that 9 is a double-sided adhesive rubber plate that can prevent the legs from falling off during floor panel installation, and 10 is cushion rubber.

The cross-sectional shape of the groove is not particularly limited as long as it has the above-mentioned effect, and may be rectangular, square, triangular, or the like.

Since the floorboard is formed by extrusion, it is much easier to manufacture than floorboards made of aluminum die-casting or glass fiber reinforced cement with integrally extruded four corners.

The material for the floorboards can be extruded.
For example, fiber-reinforced cement or thermoplastic resin may be used as long as it has the required strength.For example, fiber-reinforced cement or thermoplastic resin may be used.In the floor panel of the present invention, fiber-reinforced cement is preferable for disaster prevention. In addition to creating a space below the floorboard, it is also possible to create independent spaces equal to the number of hollow holes inside the floorboard, making it possible to arrange a large number of cables for each system, and to relocate or relocate equipment. When repairing a failure, cables can be easily identified and reeled in.

〔Example〕

A base material made by kneading ordinary Portland cement, asbestos, and the like with water was extruded and cured at high temperature and pressure to obtain a floor board made of asbestos fiber reinforced cement and having the shape shown in FIGS. 1 and 2.

The size of the floor plate is 1000mm in the extrusion direction and 500mm in the width direction.
mm/thickness 40mm, two grooves are formed near both sides in the width direction of the bottom surface of the floorboard, and one groove is formed in the center, and the hollow holes are large and small.
11 pieces were molded.

The legs consist of a washer that non-rotatably fits into a groove on the bottom of the floorboard, a nut welded to the bottom of the washer, a screw that threads into the nut and has a notch at the top, and double-sided adhesive rubber glued to the top of the washer. It consists of a cushion rubber fitted to the bottom end of the plate and screw.

At the position where the two outer grooves are provided on the floorboard,
Two perforations were made in each extrusion direction, and a washer with a nut coaxially welded was fitted into the groove with the center aligned with the perforation and adhered with a double-sided adhesive rubber plate to form a floor panel.

By rotating the screws, the floorboard can be raised and lowered to create a space below the floorboard with a height of 25 to 50 mm.

The floor panels were arranged on the installation surface, and the leg length was adjusted by rotating screws from above the panels to adjust the height and level of the floor.

When laying the floor panel, first lay the floor panel with the above dimensions, and if there is an odd dimension in the extrusion direction or width direction, the cut floor panels will be cut into two each in the extrusion direction and width direction, for a total of four. Cut and lay out one or more floorboards in the extrusion direction or width direction to a size that will be supported by the legs and completely cover the installation surface, and attach four legs to the cut floorboards. I was able to fit it and lay it in a half-sized position, and the laying surface was able to be completely laid.

Compared to conventional floor panels, there is no need for separate assembly of the legs or supplementary work for odd dimensions, no special metal fittings with a complicated structure are required to configure the legs, and height and horizontal adjustments can be made using the floor panels. Since the cables can be installed from above, the legs are fitted and glued to the floorboards, making installation easy and hassle-free, and providing a large amount of space for storing the cables.

[Effect of idea]

The effects of the floor panel of the present invention are as follows.

(1) The structure of the legs does not require special metal fittings with a complicated structure, and the floorboard and legs are integrated with adhesive, making installation easy.

(2) Since the legs can be fitted and glued to any position in the complex grooves on the bottom surface of the floorboard, the floorboard can be cut to any size in the extrusion direction and width direction to match the dimensions at the installation site. , the floorboard can always be stably supported by four or more legs.

(3) The screws built into the legs can be rotated from the top of the floorboard, making it easy to adjust the floor level.

(4) Since there are many spaces not only below the floorboard but also within the floorboard, it is easy to identify and route cables when relocating equipment or repairing a malfunction.
