Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an indoor wiring path structure useful for laying wiring on the floor in buildings such as buildings, and a wiring method using the same structure. It's about.

[Conventional technology]

In buildings that incorporate office automation equipment or advanced information equipment, there is a tendency for a wide variety of wiring materials for power, communication, and data transmission to converge on the floor. In addition, these wiring materials must be wired flexibly to accommodate any arrangement of equipment, and must be wired with minimal exposed parts to avoid deteriorating the office environment. There is a tendency.

Conventionally, conventional floor-embedded wiring pipes and cellular ducts require difficult wiring work for wiring materials, and the wiring outlets are scattered on the floor surface, so to speak, and are distributed like islands, making it difficult to expose floor wiring. In order to solve the problem of conspicuous parts, an open pit type duct is buried in the concrete floor and the openings on the floor surface of the duct are used to draw in and pull out wiring materials. Proposed.

(For example, please refer to Japanese Unexamined Patent Publication No. 102112/1983.) However, according to the 4:lz bit type floor with wiring path, wiring materials for power, communication, and data transmission can be connected to the duct. In order to coexist with each other, a wide duct is used, with the power wiring section, communication wiring section, and data transmission wiring section separated so that each section is installed independently. They are trying to increase the wiring density by laying the wires in a so-called grid pattern.

However, if the duct is wide as mentioned above, there is a concern that wide grooves will be formed in the floor structure and the strength of the floor will decrease, so the spacing must be increased. This did not contribute to reducing the exposed portion of wiring from the duct to the necessary equipment.

In addition, the opening of the duct is covered with a cover plate such as a metal plate to hide and protect the wiring material and to flatten the floor, but since the cover plate is covered with floor finishing material, the wiring part is When adding wires or pulling out wires, it is necessary to perform double work, first removing the floor covering material and then removing and reinstalling the cover plate.

The inventor of the present invention created a gutter-like groove on the surface of the floor itself, taking into consideration the problems that the oven pit method results in a large number of exposed wiring and the trouble of wiring and adding more wiring. We have already considered and proposed a wiring floor structure in which the upper opening of the groove is covered with a rigid flooring material such as a metal plate.

(Patent Application No. 6337111) [Problems to be Solved by the Invention] However, in such a floor structure with wiring grooves, it is difficult to ensure the thickness and strength of the floor due to the groove processing being applied to the concrete floor itself. In addition, it is necessary to take into account the strength of the thin flooring material placed across the opening of the groove, and the inventor's research indicates that the width and depth of the groove should be approximately 50m1. We have confirmed that.

As shown above, the amount of wiring material that can be stored in a narrow groove is severely limited, and when the density of equipment is high, it is necessary to supply wiring from adjacent grooves. The wiring density per unit area was increased by encircling the wires in a shape. However, when wiring grooves are arranged vertically and horizontally, it is necessary to construct a floor structure with the specified wiring grooves through complicated processes such as constructing the formwork that forms the wiring grooves during concrete pouring, and connecting and assembling them. I had to.

In addition, if the wiring is routed through wiring grooves that extend vertically and horizontally,
Wiring materials change direction several times and are routed, making it difficult to understand the wiring route. Therefore, it is easy to relocate wiring materials or increase wiring that is required when relocating or expanding equipment. Furthermore, it is difficult to wire wiring materials such as optical fibers that do not like bending.

Furthermore, if the grooves intersect vertically and horizontally, care must be taken when laying the flooring material having metal plates across the opening, making it rather troublesome to lay the flooring material.

Furthermore, in a floor structure with such wiring grooves, wiring materials must be relocated or additional wiring can be done by removing the flooring covering the openings of the grooves. However, since there are some areas where the flooring cannot be removed, there is a potential problem in that it is not possible to easily deal with changing the wiring or adding wiring due to changes in the layout after occupancy.

To solve this problem, it is necessary to predict the maximum number of devices expected to be installed in the future and place enough wiring material in the wiring trench in advance to accommodate the maximum number of devices. is possible. However, in that case, when the flooring in the corresponding wiring groove 1 is removed and the desired wiring material is taken out from there, the wiring material pre-wired in the premises must be cut. The solution is to pull out the cut terminal on the floor and connect it to a floor-standing outlet, etc., but the useless wire part that is cut and not used for pulling out remains in the groove, and if it is left as it is, the usefulness of the pre-wiring will be lost. I hated that I could not make full use of it and it ended up being uneconomical.

The present invention has been made to solve the above-mentioned conventional problems, and makes it easy to construct a floor structure with a wiring space, allowing flexible wiring and easy floor finishing, and also improves wiring management. It is a primary objective to provide a wiring path structure which is also advantageous.

A second purpose is to provide a wiring method that can perform flexible and efficient wiring by making the most of the usefulness of advance wiring.

[Means to solve the problem]

According to the present invention, the first object is to provide trunk wiring paths that can accommodate a large number of wiring materials at opposite ends of the room, and to provide trunk wiring paths that can accommodate a large number of wiring materials at opposite ends of the room, and to , a large number of narrow wiring grooves are formed in parallel between the opposing trunk wiring paths, and a large number of wiring materials extending from the wiring board installed near the wall are connected to a large number of wires via the trunk wiring paths. This is achieved by a wiring path structure in which the wiring paths are arranged in parallel while being distributed in the wiring grooves.

In addition, the second purpose is to distribute a large number of wiring materials in a large number of narrow wiring grooves in the above-mentioned wiring path structure so that they extend to both of the opposing main wiring paths so that they can be placed close to the opposing walls. The wires are pre-wired by pulling them into the wiring board provided in each of the wiring boards without being connected to the terminals of the board, cutting the wiring material in the wiring groove where the wires need to be drawn out, and setting up each cutting terminal after the fact. The wiring of each divided wiring material is transferred to the wiring of the extension side &I! This is achieved by a wiring method in which the terminal is connected to the terminal in 1.

Note that such a trunk wiring path can be obtained, for example, by oven pit-shaped wiring ducts arranged at both ends of the floor, but it can also be obtained by wiring ducts or cable racks arranged near walls and on the floor. It is also possible.

[Effect]

According to the indoor wiring path structure according to the present invention, when forming wiring paths in the floor, it is sufficient to form them as narrow grooves in parallel. A predetermined floor structure with wiring grooves can be formed by pouring. Moreover, it is sufficient to simply place the floor finishing material having the metal plate in the grooves arranged in parallel so that no joint exists along the longitudinal direction on the opening of the groove.

Furthermore, since the large number of wiring materials to be wired on the floor surface can be distributed in parallel grooves, it is easy to understand the wiring route, and the wiring can be wired with high straightness without being subjected to extreme bending. It becomes possible to do so.

Further, according to the wiring method according to the present invention, by pre-wiring a large number of wiring materials corresponding to the maximum arrangement density of equipment expected in the future, additional wiring can be performed when relocating or expanding equipment. It is possible to use the wiring material that has already been passed through the groove for wiring without cutting it, and when trying to pull out the wiring, it is possible to cut the wiring material that has been passed through the entire length of the groove at the required position. This can be done by pulling it out through the opening of the groove and connecting the end to a floor-standing outlet. In this case, one of the separated wiring members is a trunk wiring that takes in a large number of wide wiring members that are extended by the wiring member. It can be used as live wiring by connecting the end to a terminal on a distribution board installed near one wall via a path, and the other wiring material can be used as a live wire by connecting the terminal to a terminal on a wiring board installed near one wall. The wiring 8! was installed near the other wall via the main wiring path. It can be used as live wiring by connecting the terminal to the terminal on the panel. In this way, both wiring materials separated by cutting can be used for wiring different circuits, thereby eliminating unnecessary wiring that tends to occur in advance wiring.
