Description

  The present invention relates to a floor wiring structure in which power lines, signal lines, and the like of OA equipment are wired on a floor on which a tile carpet having a standard thickness is laid.

Tile carpets are made by bonding a carpet in which fibers such as nylon are woven into a polyvinyl chloride backing layer and cutting it into a rectangular shape. Since it can be used for various substrates and only damaged or dirty ones can be replaced, it is economical and easy to install, and is widely adopted.
There are tile carpets of various sizes, but those having a thickness of 6.5 mm are used in 90% or more, and are referred to as standard thicknesses here. The size is often 50 cm square. In rental offices, tile carpets are generally laid before the tenants are decided.

In recent years, many office automation equipment such as personal computers have been used, and so-called OA floors in which wiring is hidden under the floor as a double floor have become widespread.
If this double floor is installed in a room that was not a double floor, the construction cost will not only increase, but the floor surface will have to be raised by about 50mm, so the ceiling will be lowered and the door will open and close There is a drawback that the floor near the door must be tilted so that it can be done.

In the case where a standard thickness tile carpet is laid, wiring is generally affixed to the tile carpet using a glue or double-sided tape, and the electric wire is stored on the tile carpet. .
Since this electric wire protection case protrudes 10 mm or more from the tile carpet surface, there is a problem that it is difficult for a pedestrian to scoop or to get over a cart or a wheelchair caster.

Therefore, there is a tile carpet in which a groove for wiring is formed in advance, and an electric wire is hidden in this groove (see Patent Document 1).
In addition, there is a type in which a tile carpet-like floor unit body is laid with a gap between adjacent floors to form a groove, and an electric wire is concealed in this groove (Patent Document 2).
The tile carpet of Patent Document 1 has a thickness of 20 mm or less and is made of a surface material pile and a backing material packing material, and the wiring groove has a part of the back material cut out in a cross shape.
In addition, the floor unit of Patent Document 2 is 485 mm square and 18 mm thick particle board (a small piece of wood mixed with an adhesive and heat pressed) or plywood, etc., and is laid on the floor at 15 mm intervals. The electric wire is housed in the groove and covered with a spacer member or a transfer plate member from above.

If wiring is performed using the grooved tile carpet of Patent Document 1 or the floor unit of Patent Document 2, it does not have to be a double floor structure. However, these are special, and the price is high and it takes time to obtain. End up. Also, since the wiring path uses a pre-formed groove and the outlet is not optional, this is not the most suitable wiring for OA equipment, and the wire is bent at a right angle, It is easy to cross, and it is often the case that wiring becomes impossible.
In addition, since standard tile carpets are newly laid in the rental office before moving in, if you use the ones in the patent literature, you must remove them. There is a problem in that useless construction of rewiring occurs.

  SUMMARY OF THE INVENTION In view of the above points, the present invention aims to provide an inexpensive and practical floor wiring structure in which a floor with a standard thickness tile carpet laid is simple and the amount of protrusion on the floor is as small as possible. It is said.

  In order to solve the above problems, the floor wiring structure of the present invention is configured as follows. That is, a floor wiring structure for wiring to a floor on which a tile carpet of standard thickness is laid, a tile carpet arranged without gaps, a cutting groove formed by cutting the tile carpet along the wiring path, and a center And a base having a fitting recess that protrudes upward from the both ends, and a locking piece that fits into the fitting recess from above. The electric wire case is characterized in that the end portion of the tile carpet in the cutting groove is sandwiched from above and below and fixed to the floor surface.

Here, the tile carpet having a standard thickness means that the size is not particularly limited, but the thickness is 6.5 mm.
The wiring path may be determined arbitrarily (for example, the shortest distance) regardless of the tile carpet laying situation.
The width of the cutting groove is approximately the dimension between the fitting recesses of the base body of the wire case.

Although the electric wire storage part of an electric wire case can be made into an appropriate magnitude | size, since it is necessary to reduce the quantity which protrudes from the surface of a tile carpet as much as possible, it is good to make height 8-10 mm. Also, with regard to the width direction, a larger number of wires can be accommodated, but it will be recessed when stepped on, so it should be 30 mm or less. It is good to stand upright.
Therefore, as described in claim 2, the electric wire case has a width of 45 to 60 mm, both sides can sandwich the end of the tile carpet 8 to 14 mm, and the total height from the floor surface is 12 mm or less. desirable. The width dimension of the base body and the cover body of the electric wire case is not limited to the same dimension as long as it can sandwich the tile carpet.

In addition, since the upper surface of the electric wire case gently follows the surface of the tile carpet, the electric wire case cover body is gently curved toward both ends and thinned as described in claim 3, and the upper surface has a longitudinal direction. It is desirable to form fine irregularities.
Since both sides of the electric wire case are fixed to the tile carpet, it is not necessary to firmly fix the electric wire case to the floor surface.

In the floor wiring structure of the present invention, the end of the tile carpet is sandwiched from the top and bottom of the wire case provided with the electric wire storage part for storing the electric wire in the center part in the cut groove formed by cutting the tile carpet of the standard thickness. Since it is arranged, the amount of the protective film that comes out on the tile carpet is small compared to the case where the electric wire protection case is fixed to the surface of the conventional tile carpet, so that it is not difficult to crawl or get over the caster.
In addition, since it is performed on a tile carpet having a standard thickness, it can be carried out easily and quickly in a rental office or the like, and it is only necessary to determine the wiring route after the arrangement of the OA equipment is determined.

In addition, since the electric wire case is installed across the tile carpet, the electric wire case does not move even if the caster of the chair comes into contact with the tile carpet without being firmly fixed to the floor surface. .
When the cutting groove is formed obliquely with respect to the tile carpet, the cut end is likely to be jagged, but the electric wire case is arranged with the tile carpet sandwiched therebetween, so that the jaggedness can be hidden and it can be used as it is.

  When changing the wiring path, the initial state can be obtained simply by changing the tile carpet in which the previous cut groove is formed. In addition, it is possible to move in by exchanging one with a cutting groove, one damaged, or one dirty with a new one, and waste of resources can be saved.

Further, the electric wire case has a width of 45 to 60 mm, both sides can sandwich the end of the tile carpet 8 to 14 mm, and the total height from the floor surface is 12 mm or less (Claim 2). A portion can be secured and an appropriate amount of tile carpet can be sandwiched.
Further, if the cover body of the electric wire case is gently curved toward both end sides and the upper surface is formed with fine irregularities in the longitudinal direction (Claim 3), there is little uncomfortable feeling even when stepping on the electric wire case, It has an anti-slip effect and contributes to safety.

It is explanatory drawing which shows embodiment of the floor wiring structure of this invention. It is AA sectional drawing of the same FIG. It is a front view of the same electric wire case. It is a front view of the cover body. It is a front view of the base.

An embodiment relating to a floor wiring structure of the present invention will be described with reference to FIGS.
In this embodiment, a tile carpet having a standard thickness of 6.5 mm and a 50 cm square is laid on the floor without any gaps, and a power line, a signal line, etc. in a room (for example, an office) where OA equipment such as a personal computer or a facsimile is arranged. This will be described in the case of wiring.
Usually, the arrangement of desks, telephones, and OA devices is often determined in advance, but is often forced to be changed in the implementation stage. Therefore, it is desirable to do this after placing the desk or OA device.
FIG. 1 shows a part of a room for wiring, a tile carpet 1 having a standard thickness is laid, and a desk 10 (not shown) on which a telephone and a personal computer are placed is arranged facing each other. A power line and a telephone line are wired from the outlet of the wall 12 by the wiring path 13.
The facsimile 11 is placed at a position away from the desk 10 and wired from the desk 10 by a wiring path 14.

As shown in FIG. 2 (cross section AA in FIG. 1), the wiring path 13 and the wiring path 14 are arranged in the cutting groove 2 formed by cutting the tile carpet 1 by the electric wire case 3 including the base body 5 and the cover body 4. It is installed.
The cutting groove 2 (L in the figure) has a width of 32 mm here, and the end portion of the tile carpet 1 is sandwiched between the sandwiching piece 4b and the sandwiching piece 5b of the electric wire case 3.
The electric wire case 3 is made of a synthetic resin, and as shown in FIG. 3, the electric wire case 3 is composed of a base body 5 disposed on the floor and a cover body 4 that covers the base body 5 and has a width of 20 mm at the center. An 8 mm wire storage portion 3a is formed. And the clamping part 3b of width 10mm for clamping the edge part of the tile carpet 1 from upper and lower sides is formed in both sides.

The substrate 5 has a shape as shown in FIG. Here, the width dimension is 52 mm, and there are two fitting recesses 5 a formed by two upwardly protruding members at a position of about 10 mm from both sides of a flat plate-like member having a thickness of 1 mm.
On the other hand, the cover body 4 has a shape as shown in FIG. Here, the width dimension is 52 mm, and when viewed from the front cross section, the locking piece 4 a that curves gently in the width direction and fits into the fitting recess 5 a of the base body 5 at a position about 12 mm inside from both ends projects downward. It is installed. On the upper surface, a curved surface of 0.3 mm is continuously formed in the width direction.
The fitting recess 5a of the base body 5 and the locking piece 4a of the cover body 4 are provided with locking claws, which are locked so as not to come off when fitted.

Next, the wiring work of the wiring path 13 will be described.
When the route of the wiring path 13 is determined, a cutting line is marked on each tile carpet 1 forming the cutting groove 2, taken out and cut with a cutter, and a 32 mm cutting groove 2 is formed and rearranged.
Next, the base 5 of the electric wire case 3 is installed in the cutting groove 2. In this case, as shown in FIG. 2, the base 5 is arranged so that the sandwiching piece 5 b enters the lower side of the tile carpet 1.
And it fixes to the back surface of the base | substrate 5 with the removable adhesive (peel up type). The adhesive is used for laying the tile carpet 1 and is not used only for fixing the electric wire case 3.

Next, the power supply line 7 and the signal line 8 are arranged in the central portion of the base 5 (a place where the electric wire storage portion 3a is formed when the cover body 4 is fitted). Since the width of the electric wire storage portion 3a is about 20 mm in this embodiment, four wires can be arranged as long as the electric wire has a round cross section.
Subsequently, the cover body 4 is put on the base body 5. In this case, the locking piece 4a of the cover body 4 is fitted into the holding piece 5b of the base body 5 and pressed from above the cover body 4 until both claws are locked.
When the cover body 4 is put on the base body 5, as shown in FIG. 2, the end portion of the tile carpet 1 is sandwiched between the base body 5 and the cover body 4 in the cutting groove 2. Here, the highest part of the cover body 4 is 11.5 mm or less from the floor.
Since the height from the surface of the tile carpet 1 is only about 5 mm, and the sandwiching pieces 4b on both sides of the cover body 4 engage with the tile carpet 1 with a smooth inclination, casters such as carts and wheelchairs can be easily used. You can get over.

Note that a plurality of outlets are attached to the desk 10 and wired to OA equipment as appropriate.
Similarly to the wiring path 13, the wiring path 14 accommodates the power supply line 7 and the signal line 8 from the desk 10 to the facsimile 11. In the wiring path 14, cutting grooves 2 formed in the tile carpet 1 are formed obliquely in the tile carpet 1.
Usually, when the tile carpet 1 is cut obliquely, it becomes jagged and is not good in appearance, so it takes time and labor to align. However, when this electric wire case 3 is used, it is hidden by the clamping portion 3b, so that the work of aligning can be omitted.

  When adding or changing a wiring path, if a tile carpet and an electric wire case 3 are prepared, it can be easily performed. Further, although not described in the above embodiment, it may be necessary to bend the wiring path into an L shape, so it is desirable to prepare an L-shaped electric wire case. In addition, it is important to plan to avoid the intersection as much as possible because the intersection protrudes on the floor when the wiring paths intersect.
