Description

  The present invention relates to a wiring method for a double floor, and more particularly to a wiring method for a double floor provided with a partition wall panel.

  The double floor structure has the merit that piping and wiring can be performed in the pocket under the floor, the degree of freedom of changing the arrangement position thereof is large, and the storage under the floor is possible. In addition, when installing the partition wall, since the fixing is performed on the floor, the position of the partition wall can be changed relatively freely without being restricted by wiring under the floor. is there.

  On the other hand, although it is a double floor structure with such characteristics, in actual wiring work, for example, when an outlet is provided on a wall such as a partition wall, wiring is performed to the vicinity of the floor under the double floor below the outlet position. A hole must be drilled in the floor to guide and pull the wiring from the double floor. In such conventional wiring work, the wiring is guided to the predetermined floor position before the double floor is installed, and the wiring is raised and pulled out from the hole in the floor at the predetermined position. The electrical work, the installation of double floors, and the construction work such as drilling must be performed almost simultaneously, and it is not easy to adjust the classification and cooperation of the work. In addition, conventionally, the number of outlets of the wiring is the same as the number of outlets. Therefore, if the number of outlets is large, the number of holes increases and this adjustment becomes more difficult. Furthermore, if you want to change the position of the partition wall panel and its outlet after installing the double floor, there will be a large amount of work for removing and reattaching the double floor to change the position of the wiring. I need it.

  In the case of a detached house, there is an underfloor pocket, and it is possible to work under the floor, but especially when there is almost no underfloor like an apartment, a large-scale work such as peeling off a part of the floor Necessary.

  In order to solve the wiring problems associated with such a double floor structure, a double floor is conventionally configured as a double floor for office automation so that the wiring can be easily redrawn. Various attempts have been made to process the floor panel so that wiring vacancies are provided in advance at a plurality of locations on the floor plane, and the wiring can be pulled up from the vacant spaces. For example, a structure has been proposed in which a notch is provided in advance in a floor panel and wiring is raised from this notch (Patent Document 1).

However, it is said that the processing of the empty space by such a notch has a large burden on the manufacturing of the floor panel, and the burden on the work for accurately arranging the notch in the construction of the double floor is also said to be large. There was a problem. And even in the conventional double floor where such a void is provided by processing, the wiring under the floor before the installation of the double floor must be guided to a void position such as a floor panel notch. It is necessary to adjust so that the electrical work and the double-floor building work are almost the same time. However, in actual construction, this adjustment is not easy as described above. Moreover, it is difficult to guide the wiring to the empty space such as a notch at the predetermined position when changing the wiring due to the change of the position of the partition wall and its outlet after installing the double floor, and eventually peel off the double floor Such a large-scale work is required.
Japanese Patent No. 260961

  The invention of the present application eliminates the conventional problems from the background as described above, and in the double floor structure in which the partition walls are installed, the electrical work for wiring is doubled without requiring the processing of the floor panel. The burden of adjustment with building construction for floor installation is reduced, each work can be done separately, and even when changing the wiring, a large work such as peeling the double floor is required It is an object of the present invention to provide a double-floor wiring method capable of easily and easily performing wiring work from below the partition wall outlet to the partition wall outlet.

  The double floor wiring method of the present invention is characterized by the following in order to solve the above problems.

First: A wiring method for a double floor in which wiring to a partition wall panel installed on a double floor is performed under the floor of the double floor, and includes the following steps.

<1> Provide a wiring under the floor and temporarily partition a required portion of the wiring that can secure a front portion having a wiring length that can be extended to a predetermined plane position of the double floor where the partition wall panel is provided ; The front part of the wiring can be pulled out from the gap between the ground floor base panel and the fixed wall.

<3> The wiring front portion temporarily fixed to the fixed wall and capable of being drawn out is guided through at least one of the gaps, and is routed to a predetermined plane position of the double floor on which the partition wall panel is provided.

  <3> The wiring that can be drawn is guided through at least one of the gaps, and is routed to a predetermined plane position of the double floor on which the partition wall panel is provided.

  <4> The routed wiring is raised from under the floor and connected to a predetermined position of the partition wall panel.

  Second: In the above wiring method, wiring is connected to an outlet of the partition wall panel through a wiring passage provided at the lower part of the partition wall panel.

  According to the method of the first invention of the present application as described above, the wiring arranged in advance under the floor is temporarily fixed to the fixed wall, and then the floor panel of the double floor is provided with a gap, so that the wiring The construction does not have to be the same as the construction of the double floor. After the construction of the double floor, the electrician has the wiring that can be pulled out, and the electrical contractor guides the wiring to the specified position through the gap. can do. As a result, the burden of adjustment between electrical work and construction work is greatly reduced. In addition, since the base panel is disposed with a gap, there is no need to process the base panel like a conventional space such as a notch.

  Even if the wiring position is changed, it is not necessary to perform major work such as peeling the double floor itself. Wiring work is done by removing the floor (surface material) placed on the base panel to the minimum necessary. It can be performed.

  In this way, the wiring work to the partition wall at the predetermined floor position of the double floor is extremely simple and easy.

  Further, according to the second invention of the present application, wiring from the under floor of the double floor to the partition wall outlet and its change are further facilitated through the wiring passage at the lower part of the partition wall. The external appearance of the wiring passage can be blocked by the wiring of the baseboard.

  The present invention has the features as described above, and an embodiment thereof will be described below.

  FIG. 1 of the accompanying drawings is a floor plan view for explaining an embodiment of the method of the present invention. In the example of FIG. 1, a floor panel 2 that constitutes a double floor and a support leg 3 that supports the floor panel are disposed on a floor plane surrounded by a fixed wall 1 such as a door wall or an outer wall. . FIG. 1 also shows a planned arrangement position of the runner 5 for standing the partition wall together with the wiring 4.

  2 is an aa arrow view of FIG. 1, and FIG. 3 is an bb arrow view of FIG. 1 when the partition wall panel 6 is erected.

  If it demonstrates along this FIG.1, FIG.2 and FIG.3, the wiring in a double floor will be implemented as a next process sequence.

  <1> The wiring 4 is provided in advance under the floor, and a required portion, that is, a portion that can secure a margin of the front portion 4A having a wiring length that can be extended to at least a predetermined plane position is fixed to the fixed wall 1 with a temporary fixing member 9 Temporarily fixed by use or the like, the wiring 4 is raised, and the front portion 4A can be drawn out and guided.

  In this case, the temporary fixing and the starting position may be approximate even if not accurate. Since the gap 7B is provided between the base panel 2 and the fixed wall 1 in the next process, the position of temporary fixing is flexible, and the wiring front part 4A can be pulled out, so the labor of the work is greatly reduced. it can.

  For this reason, there is no need for accurate positioning in advance or inking, and the work is rationalized.

  <2> The respective floor panels 2 of the double floor are arranged at predetermined plane positions by providing a gap 7A between them and a gap 7B between the fixed walls 1. The base panel 2 supports the squares by support legs 3 standing on the floor slab 8, for example.

  <3> The wiring operator holds the wiring front part 4A that can be drawn out and holds the wiring front part 4A through the gaps 7B and 7A of the base panel 2 as illustrated by arrows in FIG. Pull and move. At the position of the support leg 3, the lower surface of the base panel 2 is passed.

  In this way, the wiring front portion 4A is routed to a predetermined position on the partition wall panel 6 to be arranged.

  In this procedure, the operator can hold the front portion 4A of the temporarily fixed wiring 4, and the operator can easily and easily route the wiring front portion 4A to the predetermined position via the gaps 7B and 7A. . After completion of the routing, the wiring front portion 4A is accommodated in the lower part of the double floor as shown by the arrow α in FIG. 2, and for example, from the gap 7A between the base panels 2 as illustrated in FIGS. It can be raised and guided to the partition wall panel 6 through the through hole 10 of the runner 5.

  In the <4> partition wall panel 6, as illustrated in FIG. 3, the wiring front portion 4 </ b> A is guided through the wiring passage 11 provided in the lower portion thereof and connected to the outlet.

  By providing the wiring passage 11 in the lower part of the partition wall panel 6, it is possible to perform linear feed wiring to the outlet. Therefore, wiring loss can be reduced. In addition, linear feed wiring is possible, making it easy to accommodate outlet position changes (new installation, expansion, relocation).

  New installations where there has been no outlet so far can be sent and wired as they are, and if they are added during wiring, they can be installed on a straight line of the wiring if a connecting device is provided. Further, by concealing the passage 11 with a baseboard, the appearance can be improved.

  Of course, the present invention is not limited to the above examples, and various embodiments of the present invention may be used.
