Description

  The present invention relates to a floor wiring system in which a floor panel is laid via a support member above a foundation floor to form a floor surface, and wiring is provided below the floor surface.

  2. Description of the Related Art Conventionally, a double floor floor wiring system has been used in which a floor panel is laid above a base floor made of a floor slab or the like to form a new floor surface, and wiring is provided in a space below the floor surface.

  The floor panel usually has a square shape in plan view. The floor panel protrudes downward from the lower surface of the corner of the floor panel so that the height of each floor panel can be adjusted. Lay the floor panel above the foundation floor without any gaps to form a new floor surface, or install multiple height-adjustable support members on the foundation floor, and place the floor panel on this support member A double floor is constructed by laying a plurality of floor panels above the foundation floor without gaps to form a new floor surface.

In such a floor wiring system, when the wiring is singly placed on the foundation floor, the wiring cannot be prevented at all in the case of twisting or fire, so that the duct member is provided below the floor panel 2 as shown in FIG. D is arranged so that the wiring 50 is accommodated in the duct member D. In FIG. 23, F indicates a foundation floor, 1 indicates a support member, and D ₁ indicates a lid of the duct member D.

  However, in the case where such a duct member D is disposed, the duct member D is disposed below the lower surface of the floor panel 2, and the floor panel 2 is placed on the foundation floor in order to secure a space for the duct member D to be disposed. It is necessary to lay at a high position above F, and it can be seen at a glance from which floor panel 2 of the plurality of floor panels 2 laid without gaps the duct member D is arranged. Therefore, when the wiring 50 in the duct member D is changed, the floor panel 2 that does not need to be removed is removed, which is troublesome.

  Therefore, there is one in which wiring paths are arranged between floor panels as a solution to such a problem (see, for example, Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4). In this method, adjacent floor panels are disposed apart from each other, and wiring paths are disposed between the floor panels.

  Between the floor panels, a housing part that is the main part of the wiring path is installed, and a cover whose upper surface is flush with the top surface of the floor panel is installed above the housing part to conceal the housing part and the wiring and cover it. It forms part of the floor itself. This eliminates the need to lay the floor panel at a high position above the foundation floor, and because the cover is usually formed in a different shape from the floor panel, the cover can be identified at a glance when looking at the floor surface. As a result, the position of the wiring path can be understood.

However, in the above-described Patent Documents 1 to 4, a housing part and a cover forming a wiring path are installed between floor panels, and the floor panel on which the housing part and the cover are installed is provided with the housing part and the cover. This is a dedicated floor panel provided with an erection part for erection, and is formed differently from the floor panel where the accommodating part and the cover are not erected. For this reason, when constructing a floor wiring system as shown in Patent Documents 1 to 4 using an existing support member and a floor panel, not only the housing part and the cover but also a floor panel on which the housing part and the cover are installed are newly installed. It was necessary to produce it.
