Description

  The present invention relates to a wiring material and a wiring method for an electric cable or an optical cable that are wired over a wall surface, a ceiling surface, a floor surface, or the like of a room.

  With the development of information communication, electrical cables and optical fiber cables (hereinafter referred to as wiring cables) are often additionally wired in homes and offices by installing or adding information devices such as personal computers. This wiring cable is usually routed over the wall surface or floor surface of the room, but usually a wiring member called a wiring cover or a wiring duct is used. These wiring members have a function of storing the wiring cable exposed on the wall surface or the floor so as not to be unsightly and fixing it so as not to be caught. Moreover, when there are many wiring cables, it is used also when bundling these.

  These wiring members are generally cut according to the length of the wiring according to the length of the wiring, and are combined with a corner member as appropriate, and fixed to a wall surface or floor using a fixing member such as a screw or an adhesive sheet. . In addition, the wall has the same color as the color of the wall so that the wiring does not stand out or is painted to improve the appearance. In addition, the wiring cable can provide protection, flame resistance, and fire resistance for the cable jacket, but when storing the wiring cable in the wiring member, protection, flame resistance, and fire resistance in the form of a tape or sheet. The performance is also imparted by, for example, winding a material.

  However, the conventional wiring member requires a considerably large space compared to the laid wiring cable itself, and when exposed wiring, the wiring member itself protrudes greatly from the wall surface or floor surface and is not good in appearance. There is a work of installing and fixing to the wall or the like, and the work cost for that is generated. In addition, a wiring cable may be directly attached to a wall surface or a floor surface without using a wiring member simply. In this case, it is possible to give the outer sheath of the wiring cable itself protection, flame retardancy, fire resistance, or a color similar to the wall surface. However, for example, when the color of the wall is different in one house wiring, it is necessary to prepare multiple colors of wiring cables, and the required functions differ depending on the wiring location. It becomes.

  The present invention has been made in view of the above-described circumstances, and the wiring space is small and can be wired with little conspicuousness, and further, protection, flame resistance / fire resistance, waterproofness, etc., as necessary. It is an object of the present invention to provide an inexpensive wiring material and wiring method that can be provided with the above functions and have good workability.

  In the wiring material and the wiring method according to the present invention, the wiring cable is covered with a heat-shrinkable resin tube, and the resin tube is heated and contracted to be directly fixed on the wall surface, ceiling surface, or floor surface. A heat-shrinkable resin tube having flame retardancy and / or fire resistance can be used, and there is a waterproof property between the wiring cable and the heat-shrinkable resin tube. Jelly or tape, or protective material can be provided. In addition, a fixing pillow is arranged in the resin tube and an adhesive is applied to the outer surface side to enable adhesive fixing, and a decorative tape suitable for the wall surface to be installed is attached to the outer surface of the heat-shrinkable resin tube, or Apply decorative paint to improve the appearance.

  In the present invention, by covering the wiring cable with a heat-shrinkable resin tube, the wiring cable can be protected, and functions such as flame retardancy and fire resistance can be provided. Further, a material having a predetermined function can be disposed between the wiring cable and the heat-shrinkable resin tube. For this reason, it is possible to lay the wiring cable in a form that is directly fixed to the wall surface without using a wiring member such as a conventional wiring cover or a wiring duct, and a wiring material having a necessary function at the laying position. They can be easily arranged and can be inexpensive. Furthermore, the space for wiring can be reduced and the appearance can be improved.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an outline of the form of wiring to a wall surface, a floor surface, etc. using the wiring material according to the present invention, and FIG. 2 is a diagram showing a configuration example of the wiring material according to the present invention. In the figure, 1 is a wiring cable, 2 is a heat-shrinkable resin tube (heat-shrinkable tube), 3 is a waterproof material, 4 is a protective material, 5 is a fixture, 6 is a fixed pillow, 7 is an adhesive sheet, and 8 is a decoration. Indicates a tape.

  As shown in FIG. 1, the wiring material M according to the present invention is laid directly over a wall surface or floor surface in a room such as a home or office. The wiring material M is connected via a wiring device such as an outlet P or a branching device S that is embedded or exposed in an existing wall surface, and is similar to a conventional protective cover or wiring duct, such as a wall surface or floor surface of a room. And is fixed by a fixing tool or an adhesive sheet.

  The wiring material M according to the present invention has a configuration in which the wiring cable 1 is covered with a heat-shrinkable resin tube 2 (hereinafter referred to as a heat-shrinkable tube) and the heat-shrinkable tube 2 is heated and shrunk as shown in FIG. Basic configuration. The wiring cable 1 is, for example, an electric cable that houses one or more electric wires such as a power line, a communication line, and a control line, or an optical fiber cable that houses one or more optical fibers. The heat-shrinkable tube 2 is made of a resin material such as polyolefin, fluoropolymer, or thermoplastic elastomer. This heat-shrinkable tube 2 is a resin tube that shrinks mainly in the radial direction when heated. By simply heating, the article can be covered at a relatively low cost, and the wires can be bundled, heat-resistant, insulated, and waterproof. It is widely used for protecting various articles such as anticorrosion.

  In addition to covering and protecting the wiring cable 1, the heat-shrinkable tube 2 stores a plurality of wiring cables 1 in parallel as shown in FIG. 2B, thereby binding a plurality of wiring cables. You can also. As a heat shrinking method for the heat shrinkable tube 2, a wiring cable having a length corresponding to a wiring portion to be laid is inserted into a slightly longer (about 10 to 15% longer) heat shrinkable tube, a thermostatic bath, heating It is desirable to heat in a heating atmosphere at around 100 ° C. in a furnace or the like. As a simple method when there is no heating furnace or the like, it is possible to heat shrink using a dryer or hot water. Alternatively, a wiring cable having a predetermined length or more may be covered with a heat-shrinkable tube in advance, and may be used after being cut to a predetermined length at the installation site.

  In addition, since the heat shrinkable tube 2 is usually prepared in a plurality of colors in various sizes, the size is appropriately selected according to the wiring cable to be used and the number of bundles, and the walls and atmosphere of the room for wiring. Select a color according to. As shown in FIG. 2 (A) or (B), the wiring cable 1 covered with the heat-shrinkable tube 2 is coated on the wall surface or floor surface of the room as the wiring material M using, for example, a fixture 5 or the like. Can be fixed directly. For this reason, the wiring space can be greatly reduced compared to the case of wiring using a conventional protective cover or wiring duct, and the wiring of the corner portion can be simply bent, and wiring work is extremely easy. Become.

  Furthermore, the heat-shrinkable tube 2 can be used that has flame resistance or fire resistance. It is also widely known that the wiring cable 1 is made of a flame retardant and fire resistant material and the wiring cable itself has these functions. However, in the present invention, even if the wiring cable itself does not have these functions, the heat shrinkable tube can provide flame retardancy or fire resistance.

  When covering the wiring cable 1 with the heat-shrinkable tube 2, materials having various functions can be interposed between the wiring cable 1 and the heat-shrinkable tube 2. As shown in FIG. 2C, for example, a waterproof material 3 such as a waterproof jelly or waterproof tape is interposed between the wiring cable 1 and the heat shrinkable tube 2 in order to enhance the waterproofness of the wiring cable. Can be. As a result, in the case of an optical fiber cable, it is possible to suppress water from entering the cable and prevent an increase in loss due to hydrogen intrusion into the optical fiber. Moreover, when it is an electric cable, it can prevent that an insulation resistance falls.

  In addition, when the wiring cable is laid in a place where it is easy to receive an external force and needs to be protected from the external force, a protective material is provided between the wiring cable 1 and the heat shrinkable tube 2 as shown in FIG. 4 can be arranged. The protective material 4 is formed of a metal or a resin material having mechanical strength, and is arranged so as to surround at least a semicircular circumference of the wiring cable 1 so as to surround the entire circumference of the wiring cable with two protective materials. it can. In addition, since the one side of the wiring cable 1 becomes a wall surface, the protective material 4 can use the thing of the shape by which the cross-section was U-shaped or kamaboko, and the wall surface side was open | released, for example.

  The wiring material M in which the wiring cable 1 is covered with the heat-shrinkable tube 2 can be directly fixed to the wall surface by adhesion in the same manner as a conventional protective cover and wiring duct, in addition to being directly fixed to the wall surface with the fixture 5. However, when the wiring cable is a single-core cable and is circular as shown in FIG. 2A, the contact with the wall surface is linear, and a sufficient adhesion surface cannot be secured. Therefore, as shown in FIG. 2E, a fixed pillow 6 is arranged between the wiring cable 1 and the heat shrinkable tube 2. The fixed pillow 6 may be disposed over the entire length of the wiring cable 1 or may be disposed at an appropriate interval. The fixed pillow 6 can secure a flat adhesive surface on the outer surface of the heat-shrinkable tube 2, and the wiring work can be further facilitated by attaching an adhesive material such as an adhesive sheet 7 beforehand. Can do.

  Further, as shown in FIG. 2 (F), the decorative tape 8 may be attached to the outer surface of the heat-shrinkable tube 2 or may be used by applying a decorative paint instead of the decorative tape. . By selecting the color of the heat-shrinkable tube 2 to be used, it is possible to improve the appearance by improving the uncomfortable feeling related to the color of the wiring cable, but there is a case where a heat-shrinkable tube having a satisfactory color tone is not prepared. . Such a case can be dealt with by applying a decorative tape suitable for the wall surface or applying a decorative paint. As a result, the number of types of colors of the heat-shrinkable tube prepared in advance can be reduced, which is a great advantage from the viewpoint of inventory management.

  In the present invention, the various functions described above can be used in any combination. In FIG. 2 (F), in addition to applying the decorative tape, for example, the protective material 4 in FIG. 2 (D) and the fixed pillow 6 in FIG. 2 (E) are connected to the wiring cable 1 and the heat-shrinkable tube 2. It is shown with an example in between. In the present invention, by combining the various functions described above, it is possible to easily provide a wiring material having a function in accordance with the atmosphere and environment of the laying place, and to provide a workable and inexpensive wiring. Can be implemented.

It is a figure which shows the outline of the wiring form to a wall surface, a floor surface, etc. using the wiring material M by this invention. It is a figure which shows the various structural examples of the wiring material by this invention.
