2. Description of the Related Art Recently, as office buildings and other offices have become OA, it may be insufficient to supply power to each equipment from the nearest existing outlets or the outlet of a buried electric wire buried under the floor, or where the equipment is installed. There are cases where the power supply positions are far apart, and due to the networking of information, it is often the case that cables are used to connect each device and telephones are added, which makes wiring on the floor complicated. As well as disturbing walking, trampling on these may cause a risk of disconnection.

Therefore, in an office building in which this type of equipment is frequently used, a new floor material is laid on the surface of the existing floor surface, cables are laid in the space below, and the surface is covered with a carpet or the like. This makes the floor surface flat and minimizes the exposed part of the cable.

[0004]

However, since unevenness such as unevenness is generally generated on the existing floor surface, when laying the floor material, a camber is put in and a new floor surface is applied while applying a level. It was necessary to lay it while adjusting it horizontally so that it had a predetermined height, and there was a drawback that the laying work could not be progressed due to the time required.

The present invention has been made to solve the above problems, and an object thereof is to provide a connecting pedestal capable of easily performing horizontal adjustment of each floor material laid against unevenness of an existing floor surface. It is a thing.

[0006]

To achieve the above object, according to the present invention, a large number of floor materials which are combined with each other and laid on a floor base surface are installed above the floor base surface with a gap therebetween. A connecting pedestal for connecting the lower pedestal to the floor base surface, a support bolt projecting from the center of the lower pedestal, and screwed to the periphery of the supporting bolt, The nuts that are made to look through the surface of each floor through the corner cutouts that are formed at the corners that are the intersections of the materials, and the positions of the intersections of the floors that are loosely fitted and supported around the nuts. And a connecting base for supporting the corners of the lower surface of the.

[0007]

With the above construction, the laying work is carried out by sequentially installing the corner portions of the floor material on the connecting table. At this time, regardless of the unevenness of the floor surface, laying work will be performed collectively.

After the laying work is completed, if there is unevenness on the floor surface and there is an uneven surface,
By rotating the nut that is looking at the top position of each floor using a box wrench, etc., the connecting base supporting each floor can be raised and lowered, and the surface of the floor can be adjusted horizontally. If the floor material is a square shape, 4 adjustments can be made at the same time with one adjustment.
Horizontal adjustment of the floor materials.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below.

In FIG. 1 and FIG. 2, a floor material 1 is made of a foamed lightweight material such as a square-shaped precast foamed concrete, a die-cast product such as foamed aluminum, and the like. The wiring groove portion 2 is formed in a cross shape by connecting the two parts, and the lower surface is provided with the lightening portion 3 corresponding to the depth of the groove portion 2 and four leg portions 4 projecting in the vicinity of the corner portion around it. ing. Further, an arc-shaped corner cut portion 5 is formed in a semi-circular notch at the corner portion of the apex which is the intersection of each side.

The groove width and depth of the wiring groove portion 2 are set to a sufficient volume for accommodating cables and the like, and a step portion 2a is formed in a notch on the inner upper side thereof.
Groove lids 6 and 7 are detachably arranged in a and are flush with the floor material 1 to cover the upper portion of the groove portion 2.

One groove lid 6 covers the central portion, which is the intersection of the groove portions 2, and the other groove lid 7 covers the periphery thereof. After the floor material is spread by the combination of these two types, The surface can be covered. A plurality of holes 6a, 7a for pulling out the cable are formed in each of the groove lids 6, 7 or are formed in a thin shape so that they can be opened immediately.

Each floor material 1 is installed on the existing floor surface 9 as a floor base surface so as to be adjustable in height via common connecting pedestals 8 arranged at the four corners of the floor material. This connecting pedestal 8 is a lower pedestal 8 installed on an existing floor 9 as shown in FIGS.
a, a bolt 8b integrally provided on the lower center of the lower base 8a by welding or the like, an adjuster nut 8c that is screwed onto the bolt 8b and moves up and down, and upper and lower flanges 8d welded around the adjuster nut, It is composed of a regular quadrangular connecting base 8f that is rotatably supported between 8e and that supports the corners of the floor members 1.

The connecting base 8f is composed of upper and lower flanges 8d and 8e.
The nut 8c is supported by the nut 8c so as to be rotatable relative to the flange 8d, 8e and the connecting base 8f.
A lubricating oil such as grease is applied between and so that the connecting base 8 can be smoothly rotated. Also,
The diameter of the upper flange 8d is small corresponding to the gap formed by the corner cut portion 5.

Further, a sheet 8g for preventing slippage such as rubber is integrally attached to the bottom surface of the lower base 8a to prevent the base 8a from moving after being installed.

In the above construction, when the floor material 1 is laid, the connection pedestals 8 are arranged in advance at the intersections of the regular squares of the floor material 1, that is, at the four corners of each floor material 1, and then the connection base 8f. While installing the corners of each floor material 1, the flooring work is performed.

As a result, one connecting pedestal 8 simultaneously supports the four floor members 1 at one place, and when the corner cuts 5 are gathered, the joining point portion becomes a circular groove-shaped adjuster. The nuts 8c are assembled in a state in which they are seen through the front side of the floor material 1, and the grooves 2 of each floor material 1 are continuous in a cross shape.

In the assembling process, it is not necessary to carry out horizontal adjustment, and when all the floor materials 1 are spread and unevenness has occurred, as shown in FIG.
Inserting 0 into the circular groove surrounded by each corner cut 5, engaging the adjuster nut 8c and turning it to the right or left moves the connecting base 8f up and down.

At this time, the connecting base 8f tries to rotate together, but since the square portion of the connecting base 8f is in contact with the leg portion 4 or the like, the connecting base 8f is prevented from rotating and can only move up and down. The levelness is adjusted by being pushed up or down, and the levelness of four floor materials 1 at the same time is adjusted by one leveling operation.

After adjusting the levelness, cables are laid in the wiring groove 2 according to the wiring plan, and then the groove lids 6 and 7 are used to cover the cables. It should be noted that at the position where the cable ends are pulled out, they are pulled out through the pull-out holes 6a and 7a.

Thereafter, a floor carpet 11 such as a tile carpet is laid on the surface of the floor material 1 (see FIG. 2), and the cable is pulled out from a required position. Alternatively, installing an outlet and other connecting tools at this position will complete the floor interior work.

After the floor interior work is completed, office equipment, furniture, etc. can be arranged at the planned positions, and the cables or connecting tools drawn from the new floor can be connected to the cords of the nearest equipment at the shortest distance.

Although these loads are mainly received on the surface of the flooring 1, even if the groove covers 6 and 7 are partially covered, by constructing them with a strong material, It can be satisfactorily held without being loaded on the internal cable.

When the wiring or the wiring outlet is changed after the floor interior work, the carpet 11 is peeled off and the cables 6 in the groove 2 are exposed by removing the groove covers 6 and 7. It is possible to easily cope with wiring changes and changes in the take-out position by changing the wiring, pulling it out to another position, or adding a connecting tool such as an outlet.

Furthermore, the present invention can be applied not only to the existing floor surface as in the above embodiment but also to a new floor.

[0026]

As described above in detail with reference to the embodiments, in the pedestal for connecting the prefabricated flooring according to the present invention,
When the corners of the floor material are installed on the connecting table, only the laying work is performed in a lump, and after the laying work is completed, there is unevenness on the floor base surface Can insert the box wrench into the nut facing the apex of each floor and rotate it to raise and lower the connecting base that supports each floor and adjust the surface of the floor horizontally. If the floor material has a square shape, the horizontal adjustment of four floor materials can be performed at the same time by adjusting one position.

Therefore, according to the present invention, the leveling degree can be adjusted from the upper side of the flooring material after the flooring material is assembled, as compared with the conventional leveling operation, so that the workability is simple and the efficiency is high.
