Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling floor slab that is installed on a floor surface and can incorporate cables such as electric wires.

[0002]

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 device from the nearest existing outlets or the outlet of a buried electric wire buried under the floor. 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 risk of breaking the wire or pulling out the plug by stepping on or hooking these.

Therefore, in an office building in which this type of equipment is frequently used, after the necessary wiring is performed on the existing floor,
A new floor slab is laid on top of this with a predetermined space and the surface is covered with carpet or the like.

[0004]

However, since unevenness such as unevenness is generally generated on the existing floor surface, when installing a new floor slab, insert a camber or the like and apply a level to the new floor. The surface must be horizontally adjusted so that it has a predetermined height, and there is a drawback that it takes time and laying work is not progressed.

Moreover, after the wiring is completed and the floor slab is laid, the wiring and the wiring take-out position cannot be easily changed. That is, in order to change the wiring and the wiring take-out position, the floor slab must be removed once. For this reason, the floor slab must be disassembled and reassembled when the interior is redesigned or the equipment is relocated, which is troublesome.

The present invention has been made to solve the above problems, and its object is to enable easy horizontal adjustment for unevenness of an existing floor surface, such as an existing floor surface, and to change or arrange the floor slab after laying. (EN) Provided is an assembling floor slab capable of easily changing the wiring and the wiring take-out position according to the change.

[0007]

In order to achieve the above-mentioned object, the present invention is a floor slab in which a large number of floor slabs are combined and laid, and the floor slabs adjacent to each other on the surface of each floor slab. A continuous wiring groove is engraved between the floor slabs, and an installation step is formed in the lower corner of the floor slab.
Further, a lid that is detachably installed on the upper surface of each groove and is flush with the surface of the floor slab, and a corner angle of the intersection position of each floor slab that is disposed between the step and the floor base surface. It is characterized in that it is provided with a height adjustable connecting base for supporting the parts.

[0008]

With the above construction, the floor slab can be horizontally adjusted by rotating the adjuster screw of the connecting base when the floor surface is uneven.

After the floor slab is spread, the wiring groove is continuous, and the cables are wired therein and covered with a lid to form a flat floor surface.

When changing the wiring or the wiring outlet, the cables in the groove are exposed by removing the lid. Therefore, it is necessary to change the routing of this, pull in, pull out, or add a connector such as an outlet. Wiring can be changed.

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

1 and 2, a floor slab 1 is a molded product having a predetermined thickness and made of a foamed lightweight material such as a die-cast product such as a precast foamed concrete or a foamed aluminum having a square shape. The groove portion 2 is carved in a cross shape. Further, around the groove portion 2, a hollow portion 3 is opened inside the floor slab 1 so as to reduce the weight by lightening. Further, a step 4 for installation is cut out at the bottom of each corner of the floor slab 1.

The groove width and depth of the wiring groove portion 2 are set to have a sufficient volume for accommodating cables, and a step portion 2a is formed in a notch on the inner upper portion thereof, and this step portion 2a is formed. The lids 5 and 6 are detachably arranged, and cover the upper part of the groove 2 on the same plane as the floor slab 1.

The lid 5 covers the intersections of the respective groove portions 2, and the lid 6 covers four peripheral portions thereof. After the floor slab 1 is spread, these two types of grooves 5 and 6 are combined to form the surface of the groove portion 2. Can be covered on the same plane. A plurality of holes 5a, 6a for pulling out the cables are opened in each of the lids 5, 6, or these portions are thinned so that they can be opened immediately.

The corners of each floor slab 1 are supported so that their heights can be adjusted by a common connecting base 7 arranged at the intersections thereof. The connecting base 7 is a step portion 4 for installing the floor slab 1 and an existing floor surface 8.
As shown in FIG. 3, a disk-shaped lower base 7a also serving as an adjusting knob installed on the existing floor surface 8 is disposed between
And a bolt 7b integrally formed at the center of the upper portion of the lower table 7a by welding or the like, and a disk-shaped installation table 7c that is screwed onto the bolt 7b and moves up and down. Positioning projections 7d for allocating the installation positions of the plate 1 are radially provided at 90 ° intervals.

Further, reference numeral 9 indicates that the wiring is completed and the lids 5, 6 are
A carpet such as a tile carpet that is laid on the upper surface of the floor slab 1 after the surface is covered with.

In the construction described above, when the floor slab 1 is laid, the laying work is performed while placing the connecting bases 7 between the installation step portions 4 at the four corners of each floor slab 1 and the existing floor surface 8. . In this state, the lower surface of each floor slab 1 serves as an installation surface, and the four corners are supported by the connecting stand 7. At this time, when the floor slab 1 is tilted due to the unevenness of the existing floor surface 8, the lower slab 7a is rotated and the installation base 7c is moved up and down, so that the floor slab 1 is pushed up or pushed down and horizontal adjustment is performed. It Since this portion is an intersection of the floor slabs 1 to be joined to each other, the horizontal adjustment of four floor slabs 1 can be simultaneously performed by one adjustment work.

FIGS. 4 and 5 show the floor slab 1 arranged on the existing floor surface 10 by the above-mentioned assembly and adjustment work. The wiring groove 2 is continuous vertically and horizontally on the surface of each floor slab 1. Therefore, in this state, cables are laid in the wiring groove 2 according to the wiring plan, and then the groove 2 is formed by the lids 5 and 6.
Cover. In addition, at the position where the cables are pulled out,
Pull out through the pull-out holes 5a and 6a.

After that, the carpet 9 is laid on the surface of the floor slab 1 and the cable is pulled out to 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 by the surface of the floor slab 1 and the connecting base 7, they are made of a strong material even if they partially cover the lids 5 and 6. As a result, the internal cable can be satisfactorily held without being loaded.

When the wiring or the wiring outlet is changed after the floor interior work, the carpet 9 is peeled off and the lid 5 is removed.
By removing 6, the cables in the groove 2 are exposed, so it is possible to easily change the 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.

[0023]

As described above in detail with reference to the embodiments, in the prefabricated floor slab according to the present invention, each floor is adjusted by rotating and adjusting the adjuster screw of the connecting base for unevenness of the floor base surface. Since the plate can be adjusted horizontally, compared to the case of laying a floor slab while hitting a conventional camber,
At the same time, the horizontal adjustment of the four floor slabs simplifies the adjustment work and has the advantage of greatly improving work efficiency.

Further, according to the present invention, when the wiring or the wiring outlet is changed, the cables in the groove are exposed by removing the lid. Therefore, it is necessary to change the routing of the cables or pull them out, or to connect an outlet or the like. Since the wiring can be changed and the take-out position can be changed by adding a tool, there is an advantage that the wiring work accompanying the pattern change and the device arrangement change can be easily performed.
