Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for constructing a rising portion of a tape-shaped 70-a cable and a floor cable rising riverside A.

Conventionally, the following two methods have been mainly used for wiring telephones and the like on the floors of offices and the like. One method is to install conduit pipes in the floor in advance and then route the cables afterwards.Another method is to route the cables on the floor and cover them with wire protectors. This is a method of protection.

However, although the former method has the advantage that the cables can be wired without protruding from the floor surface, it has the disadvantage that the construction cost is high and there is a lack of continuity when changing the wiring. The latter method has the advantage that it is easy to install and has low construction costs because it is only necessary to cover the cables routed on the floor with wire protectors, but since the wire protectors protrude above the floor, it is difficult for pedestrians or objects to pass through. There is a problem that it may become a hindrance to people who are blind, and it may spoil the aesthetics of the room for people who are blind.

In consideration of these issues, the applicant filed the U.S. Pat.
No. 379, Akira Jigan! In t-1/14!20, etc., we proposed a "floor wiring cable" (hereinafter referred to as "floor cable"). A floor cable is made by arranging a large number of conductors horizontally in a row at intervals, or in two rows with a shield layer in between, and covering them with an insulating coating to form a tape-like structure as a whole. Because it is thin, it can be laid under carpets and wired without protruding from the floor, and it has good crosstalk characteristics, making it suitable for telephone wiring, etc., but how do you get this floor cable up from the floor? There remained the problem of how to use the floor cable, which is tape-shaped and therefore harder to bend in the width direction than in the thickness direction, for wiring after startup.

This invention was proposed in consideration of the above-mentioned circumstances, and consists of laying a floor cable along the floor using a tape-like TT,
After bending it in the thickness direction and standing it up, it is easy to roll the floor cable and form it into a tube shape, and by using a starting jig, it is possible to reinforce the rising part where external force is easily applied. The purpose is to

The construction method according to the present invention includes (a) laying a tape-shaped floor cable along the floor, ←) bending the floor cable in its thickness direction and standing it up, and The process consists of forming the floor cable into a tube shape with the edges facing each other or overlapping each other.

The following is a floor cable installation method used when laying floor cables using this method. The present invention will be specifically explained based on an example of i&A.

Figures 1 to 4 show the seventh embodiment of the floor cable starting jig. It has become. A horizontal cable passing groove 5 is formed on the top surface of the mounting plate 1, into which the tape-shaped floor cable 4 is fitted. These are determined in accordance with the thickness and width of the. Also, this mounting plate 1
Above, a cylindrical support part 3 has an axis directed in the cable wiring direction (vertically upward in the embodiment), and an inner peripheral surface communicates with the cable passage groove 5 via the guide surface of the guide part 2. The inner diameter of this supporting portion 3 is approximately equal to the outer diameter of a tube when the tape-shaped floor cable 4 is formed into a tube shape with both side edges facing each other. Further, the guide plate 2 has a guide surface that follows the shape of the floor cable 4 in a transition state when it is formed from a tape shape to a tube shape, and integrally connects the mounting plate 1 and the support part 3. . Further, the mounting plate 1 is formed with a bolt hole 6 through which a bolt for fixing the floor cable standing jig to the floor or the like is inserted.

The floor cable raising jig is formed by integral molding of plastic, hard rubber, or the like, or by bending and welding a steel plate.

When constructing the flare cable starting section using the floor cable starting jig configured as shown in the figure, first lay the tape-shaped floor cable 4 along the floor 7, and then attach the mounting plate 1 to the floor cable 4. is fixed to the floor 7 at the starting point by bolting or gluing, and the floor cable 4 is fitted into the cable passage groove 5 of this mounting plate 16, bent in the thickness direction along the guide part 2, and the floor cable 4 is It is inserted into the support part 3 while molding it into a tube shape with both side edges facing each other or overlapping each other, and then pulled out from the upper part of the support part 3.

After the floor cable 4 is set up in this way, a part of the carpet 8 is cut out to an extent that the guide part 2 of the jig for setting up the flare cable can pass through, and this carpet 8 is used for setting up the cable. to cover the mounting plate 1 and floor cable 4.

When the floor cable is set up using the floor cable start-up jig as described above, the tape-shaped floor cable 3 is bent in the thickness direction and then formed into a tube shape. By bending the cable 3 with a small curvature, the raised portion can be made small, and furthermore, this raised portion is protected from external forces by the guide portion 2 and the support portion 3. In addition, if the floor cable 4 pulled out from the support part 3 is kept in a tube state by taping or the like, it can be easily bent in each direction, and the floor cable 4 can be easily bent in each direction.
Since the width dimension can be made smaller than that in the tape-like case, wiring after startup becomes easier.

Next, FIGS. 1 and 2 show a second embodiment of this cable-starting jig, in which the supporting part 3A of this cable-starting jig has a part of the side surface overlapped. It is formed in a cylindrical shape, and when using this cable startup jig, the tube-shaped 7!
7 Fit the cable 4, and after fitting, the outer periphery of the three supporting parts can be fixed with taping etc. In this case, there is no need to pass the floor cable 4 through the supporting part 3A. This shows a third embodiment of the start-up jig, in which a cable passage groove 5 is formed on the lower surface of the mounting plate IA, and this cable passage groove 5 and the inner guide surface of the guide part 2 are connected to the mounting plate IA. Communication is established through the formed communication hole 9, and a large number of hook-shaped protrusions 10 that are engaged with the fibers on the surface of the carpet 8 are formed in a portion of the lower surface of the mounting plate where the cable passage groove 5 is not formed. A locking tape 11 (for example, on the male side of a magic fastener) is attached.

This cable support jig is used when wiring the floor cable 4 on the carpet 8. Place the mounting plate IA on the floor cable 4, fit the 70-a cable 4 into the five cable passage grooves, and The cable 4 is bent upward and inserted into the communication hole 9, and then, as in the seventh embodiment, the 70-a cable 4 is formed into a tube shape and inserted into the support part 3 and raised upward. , the cable support jig is fixed to the carpet 8 using the locking tape 10.

In addition, in this third embodiment, instead of the locking tape 11, adhesive or adhesive is applied to the lower surface of the mounting plate IA,
The cable support jig may be fixed to the carpet 8 by these, and the carpet 8 may be provided with a tape (for example, the female side of a magic fastener) provided with a large number of loop-shaped protrusions that engage with the locking tape 10. You may also affix K.

As is clear from the above explanation, the present invention is a method in which a tape-shaped floor cable is bent in the thickness direction and then stood up, and then this floor cable is formed into a tube shape. This has the effect that the raised portion can be made smaller and the floor cable can be easily bent in each direction after startup, making wiring easier.
