BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a number of floor materials which are laid on an underfloor surface such as an existing floor surface and into which cables such as electric wires can be incorporated and which are kept under the floor level while maintaining a horizontal level. The present invention relates to a connecting pedestal for supporting on the ground.

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, there is a fear of breaking the wire due to stepping on these.

Therefore, in an office building in which this kind of equipment is frequently used, a new floor material is laid on the surface of the existing floor surface, cables are housed in the space below the floor material, and wiring is performed.
By covering the new floor surface with a carpet, etc., the surface is flattened and the exposed portion of the cable is minimized.

[0004]

However, since unevenness such as unevenness is generally generated on the existing floor surface, when laying a new floor material, a camber is put in and a new floor is applied while applying a level. The surface must be laid while adjusting the level so that it has a predetermined height, and there is a drawback that the laying work does not progress due to the time required.

The present invention solves the above problems, and an object thereof is to facilitate horizontal adjustment of a large number of newly laid floor materials against unevenness of a floor base surface such as an existing floor surface. It provides a connected pedestal.

[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 surface are placed above the floor surface with a gap. A connecting pedestal for rotatably fitting the lower pedestal installed on the floor base surface and the center of the lower pedestal, and connecting the pedestals to the corners at the intersections of the floor materials. An adjuster bolt whose head is seen through the surface of each floor through a notched corner cut portion, a nut screwed to the adjuster bolt, and integrally provided around the nut, and each floor. And a connecting base for supporting the corners of the lower surface at the intersection point of the members.

[0007]

With the above construction, the laying work is performed by installing the corner portions of the floor material on the connecting table. At this time, it is not necessary to adjust the level regardless of the unevenness of the floor surface.

After the laying work, if there is unevenness on the floor surface and there is a part that is not flat, use a box wrench or the like for the bolt head that is looking at the intersection of the floor materials. By using it to rotate, the connecting base that supports each floor moves up and down, pushing up or pushing down the floor,
The surface of each floor can be leveled. 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.

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. To form a cross-shaped wiring groove portion 2, and the lower surface is provided with a lightening portion 3 corresponding to the depth of the groove portion 2 and four leg portions 4 projecting in the vicinity of corner portions around the lightening portion 3. There is. Further, a semicircular corner cut portion 5 is cut out at a corner portion which is an intersection point 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 the two types, The surface can be covered. This groove lid 6,
A plurality of holes 6a, 7a for pulling out the cable are formed in the opening 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 through a common connecting pedestal 8 arranged at the four corners of the intersections so that the height can be adjusted.

This connecting base 8 is, as shown in FIGS.
A base 10 installed on an existing floor surface 9 as a floor base surface,
An adjuster bolt 11, which is rotatably loosely fitted to the upper center of the lower base 10, a nut 12 that is screwed onto the adjuster bolt 11 and moves up and down, and welded around the nut 12,
In addition, it is roughly configured from a regular quadrangular connecting base 14 that supports the corner portions of each floor material 1.

The lower base 10 has a diameter corresponding to the size of the space surrounded by the legs 4 in a state in which the floor materials 1 are assembled,
And a part of the spherical surface with a raised center,
An edge member 15 made of rubber or the like for slip prevention is fitted around the periphery.

The lower part of the adjuster bolt 11 is loosely fitted in a shaft hole 10a opened at the center of the lower table 10, and is supported by the lower table 10 by a lower flange 16 and an upper flange 17 welded to the lower and upper outer peripheries thereof. The bolt head 11a formed on the top of the bolt is seen above the circular groove surrounded by the corner cuts 5.

The upper flange 17 is the lower base 1
Since they contact each other with a spherical shape that matches the spherical shape of 0, even if the bolt 11 is tilted, bending force is prevented from being applied to this portion of the bolt 11. In addition, by applying a lubricant such as silicon grease between the flanges 16 and 17 and the lower base 10, smooth rotation is achieved.

Further, a corrugation press process 14a is concentrically formed from the center of the connecting base 14 to reinforce the load of the connecting base 14.

In the construction described above, when the floor material 1 is spread, the connecting pedestals 8 are arranged at the intersections of the squares of the floor material 1 and the corner portions of each floor material 1 are attached to the connecting base 14. Perform paving work while installing.

As a result, one connecting pedestal 8 simultaneously supports the four floor members 1 at one place, and the corner cut portions 5 make the joining points of the respective floor members 1 in the shape of a circular groove so that the adjuster can be used. The heads 11a of the bolts 11 are assembled with the front side of the floor material 1 being viewed, and the grooves 2 of each floor material 1 are continuous in a cross shape.

Incidentally, it is not necessary to carry out horizontal adjustment in the assembling process, and when all the floor materials 1 have been spread and unevenness has occurred, as shown in FIG.
8 is inserted into the circular groove surrounded by the corner cut portion 5, engages with the head portion 11a of the adjuster bolt 11 and is turned clockwise or counterclockwise. Moves up and down.

At this time, the connecting base 14 tries to rotate together, but the square corners of the connecting base 14 come into contact with the legs 4 and the like, so that they are prevented from rotating. As a result, the levelness of each of the four floor members 1 can be adjusted at the same time by adjusting work at one place.

Even if the lower pedestal 10 of the connecting pedestal 8 is tilted due to unevenness, the bolts 11 are attached to the pedestal 14 for each floor material 1.
The average load is applied to maintain a vertical posture, which makes it highly flexible with respect to unevenness.

After adjusting the levelness, cables are laid in the wiring groove 2 in accordance with 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 tile carpet or the like (not shown) is laid on the surface of the floor material 1, 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 placed at the planned positions, and the cables of the nearest equipment can be connected to the cables or connecting tools drawn from the new floor surface in the shortest distance.

Although these loads are mainly received on the surface of the floor material 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 is peeled off and the groove lid 6 is removed.
By removing 7, the cables in the groove 2 are exposed, so it is possible to easily change wiring or change the take-out position by changing the routing of this, pulling it out to another position, or adding a connector such as an outlet. be able to.

Further, the present invention can be applied not only to the existing floor surface of the above-mentioned embodiment but also to a new floor base surface.

[0030]

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 connection stand, only the laying work is performed in a lump, and after the laying work is completed, there is some unevenness on the floor base surface, and there is a part that is not flat. Is
By inserting a box wrench or the like into the bolt head that is looking at the intersection of each floor material and rotating it, the connecting base supporting each floor material can be raised and lowered, and the surface of the floor material can be adjusted 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, since the horizontal adjustment can be performed from the upper side of the floor after assembling the floor, the work is simple and highly efficient as compared with the conventional horizontal adjustment work.
