Description

[Detailed Description of the Invention] [Background and Objectives of the Invention] The present invention provides a carpet installation method for a so-called under-carpet cable in which a flat cable is mainly installed crawling on a floor surface and covered with a scare carpet from above. That is.

A so-called under-carpet cable, in which a flat cable is mainly laid over a concrete floor and covered with a scare carpet, was proposed by Thomas & Betts, Inc. in the United States. (If necessary, please refer to Japanese Unexamined Patent Publication No. 56-22077.) FIG. 1 is a cross-sectional explanatory diagram showing the relationship between such an undercarpet cable and a carpet.

As is clear from Fig. 1, the flat cable 3 is mainly protected from above and below with plastic tape, etc., and is further protected from the top by metal tape 4 such as copper tape for electrical grounding, to prevent sharp metal objects from penetrating the cable. Corrosion-resistant iron tape 5 and the like for mechanical protection are sequentially covered, and both sides of the wide iron tape 5 are fixed to the floor surface with an adhesive layer 7, and then a square is applied from above the cable assembly. Carpet 6 is laid out with both edges protruding.

By the way, in the past, when laying such scare carpets, no special consideration was given to the method of fixing them to the floor surface, and in general, they were spread on the floor surface before cable installation, and every few rows were glued to the floor surface. The method was to attach it to the When installing the cable, the carpet along the cable installation route was once removed, the cable was installed on the exposed concrete floor surface, and then the removed carpet was re-laid.

When constructing a carpet, no special consideration is given to the misalignment of cables on the floor, as mentioned above, so when you walk on the carpet, the carpet shifts and the cables that are crawling underneath, especially the flat cable 3. Particularly in areas where the carpet is laid, such as corners, the tread pressure applied to the floor surface is directional, so the cables may become misaligned even when the carpet misalignment is not noticeable.

In order to solve this problem, it is conceivable to glue and fix all of the scare carpets laid on the floor to the floor, but in that case, it would be necessary to change the indoor layout (desk In the case of rewiring or additional wiring that is necessary due to relocation of equipment (rearrangement of equipment, etc.), the work of stripping off the carpet becomes troublesome, and problems arise in the workability of the wiring.

The present invention solves the above-mentioned conventional problems, prevents the carpet from shifting which would cause the carpet to shift relative to the undercarpet cable, and also makes it easy to change the wiring or increase the wiring for the undercarpet cable. , which aims to provide a carpet laying method.

[Summary of the invention]

The method of installing a carpet for an undercarpet cable provided by the present invention is to install up to three scare carpets that cover the top of an undercarpet cable that is installed crawling on the floor surface and are connected in the length direction of the cable. At least one of them is glued and fixed to the floor surface, and one or two scare carpets connected from the side of the undercarpet cable are glued and fixed to each scare carpet glued and fixed to the floor surface. If there is a scare carpet that is not glued and fixed with the three scare carpets that cover the above undercarpet cable, install one scare carpet that is connected from the side of the undercarpet cable for each one. It is characterized by adhesively fixing one piece of the scare carpet that is connected to the tip of one piece of the scare carpet that is either adhesively fixed to the floor surface or connected without being adhesively fixed.

〔Example〕

FIG. 2 is an explanatory plan view showing a state in which the carpet is fixed with adhesive or not fixed with adhesive by the method of the present invention, and the shaded area is shown as the part fixed with adhesive.

In the example of a, three scare carpets 10 are glued and fixed to the floor surface, covering the under carpet cable 8 which is stretched over the floor surface and connected in the length direction of the cable. For each scare carpet 10 fixed with adhesive, one piece of scare carpet 9, 11 on each side, which is connected to the side of the undercarpet cable 8, is not fixed with adhesive.

In this embodiment, the undercarpet cable 8
Since all three scare carpets 10 covering the under carpet are fixed to the floor with adhesive, it is difficult to rewire the under carpet cable 8, but the adjacent scare carpets 9 and 11 can be fixed without adhesive. Therefore, it is easy to accommodate additional wiring.

In the example b, the middle one of the three scare carpets 10 that covers the undercarpet cable 8 that is stretched over the floor and is connected in the length direction of the cable is fixed to the floor with adhesive. However, the two front and rear carpets 10' are not fixed with adhesive, and one of these square carpets 10, 10' is fixed with adhesive in the middle, and a cable is connected from the side of the undercarpet cable 8. The undercarpet cable 8 is attached to the undercarpet cable 10', which is fixed without adhesive on the front and rear sides, without adhesively fixing the scare carpets 9 and 11 on each side.
One piece of scare carpet 9', 11' on each side connected from both sides of the carpet is fixed by adhesive.

In example c, one of the three scare carpets 10 at one end of the three scare carpets that cover the undercarpet cable 8 and are connected in the length direction of the cable is placed on the floor. The other end of the scare carpet is not adhesively fixed to the floor surface, and the other end of the scare carpet is not adhesively fixed to the floor surface. For each of the two scare carpets 10' that are not fixed to the floor surface in the middle, one scare carpet 9', 11' on each side connected to the side of the undercarpet cable is fixed to the floor surface by adhesive bonding. , one scare carpet 9, 11 on each side connected to the side of the undercarpet cable is not adhesively fixed to each of the front and rear scare carpets 10 fixed to the floor surface with adhesive. .

In the example of d, one of the up to three scare carpets that cover the undercarpet cable 8 that is stretched over the floor surface and extends in the length direction of the cable. One of the end pieces 10 is fixed to the floor with adhesive, and the remaining two pieces 10' are not fixed with adhesive, and the undercarpet cable is One piece of the scare carpet 11 connected from one side is not adhesively fixed, and in the same way, two pieces of scare carpets 9 ₁ and 9 ₂ which are connected from the other side are not adhesively fixed, and on the other hand, the under carpet cable is For each of the two consecutive scare carpets 10' that are not adhesively fixed to the floor surface,
A piece of scare carpet 11' is glued and fixed to one end of the undercarpet cable, and a piece of scare carpet ₉₂ that is not glued and fixed is made to the other side of the cable. A series of scare carpets 9 ₁ ′ are adhesively fixed to the floor surface, and such a pattern is repeated every three in the length direction of the cable.

In the example e, out of the five scare carpets that cover the undercarpet cable 8 stretched over the floor and are connected in the length direction of the cable, the front and rear ends and the three central three pieces 10 are used. It is fixed to the floor surface with adhesive, and every other sheet 10' sandwiched between the three sheets is not fixed with adhesive.

Therefore, from any side in the longitudinal direction of the cable, two of the three cables are fixed with adhesive and one is fixed without adhesive.

Therefore, for the scare carpet 10 adhesively fixed to the floor surface as described above, up to two scare carpets 9 ₁ , 9 ₂ , 11 ₁ , 11 connected on both sides of the undercarpet cable are attached. ₂ is not adhesively fixed, and on the other hand, for the scare carpet 10' which is non-adhesively fixed on the undercarpet cable, there is one scarecarpet 9 ₂ on each side extending on both sides of the undercarpet cable. 11 ₁ is not fixed with adhesive, and each of the scare carpets 9 ₁ ′ and 11 ₂ ′ that are connected at the tip of each scare carpet that is fixed without adhesive is fixed to the floor surface with adhesive. .

In the above four examples b to e, two of the three scare carpets covering the undercarpet cable are fixed without adhesive, so these square carpets fixed without adhesive have already been peeled off. It is possible to easily rewire installed undercarpet cables. Also, there are scare carpets on the side of the beams that are fixed non-necessarily.
Can accommodate additional cable wiring.

In addition, individual scare carpets can be fixed with adhesive directly on the concrete floor, or
This may be done indirectly using double-sided adhesive tape.

Furthermore, when adhering, the entire surface of one carpet may be bonded, or a partial surface may be bonded.

〔Effect of the invention〕

As explained above, according to the method for installing a carpet for an undercarpet cable according to the present invention, three carpets are installed that cover the top of the undercarpet cable that is installed crawling on the floor surface and are connected in the length direction of the cable. At least one of the up to three scare carpets is fixed, and if there is a scare carpet that is not glued and fixed to the floor surface with those three scare carpets, the side of the undercarpet cable is A single scare carpet that is connected to the floor is adhesively fixed to the floor surface, or a single scare carpet that is connected without being adhesively fixed to the floor surface is adhesively fixed to the floor surface. Not only the scare carpet that covers the undercarpet cable, but also the scare carpet that covers the undercarpet cable without being adhesively fixed to the floor surface is designed to ensure that it does not shift. This solves the problem of the undercarpet cable, especially the flat cable body, shifting due to displacement of the carpet, and prevents accidents such as wrinkles that may occur due to displacement, and ground faults due to disconnection, correlated short circuits, or protruding conductors. It is possible to provide an undercarpet cable track with high safety.

In addition, one or two scare carpets connected from the side of the undercarpet cable are not adhesively fixed to the scare carpet that is adhesively fixed to the floor surface and covers the undercarpet cable, and In addition, it is also possible to fix the square carpet that covers the undercarpet cable without adhesive, which simplifies the work of laying the scare carpet that requires fixing with adhesive. By peeling off the carpet, it becomes easy to rewire the under carpet cable that has already been installed or to increase the number of cables.

Therefore, the intended purpose is to provide a carpet laying method that prevents the carpet from shifting in relation to the undercarpet cable, and also allows for easy rewiring and additional wiring for the undercarpet cable. has been achieved and is of great practical benefit.
