Description

  The present invention relates to a floor panel support mechanism on an OA floor (or referred to as a free access floor) that can smoothly perform under-floor processing of information wiring and power supply wiring in an office or the like.

  With the advance of IT, in general offices and the like, it has become common to adopt an OA floor that can smoothly process information wiring and power wiring under the floor.

  The OA floor has a configuration in which a floor panel is supported above a floor slab by a support member, and information wiring and power supply wiring are laid in a space formed between the floor panel and the floor slab. As shown in FIG. 5, when the information wiring and the power supply wiring are laid together, they are complicated and difficult to manage, and the problem of noise due to the proximity of the information wiring and the power supply wiring tends to occur.

In order to solve such problems, for example, as shown in Patent Document 2, a wiring arrangement panel is installed on the side surface of the support member of the floor panel, or as shown in Patent Document 3. There is a conventional technique in which a wiring guide is formed in advance by installing a wiring groove between support members of a floor panel, and the wiring is laid along the wiring guide. In such a conventional technique, there is a configuration in which the wiring guides are configured in a two-stage manner so that the information wiring and the power supply wiring are separated vertically.

In the conventional technology described above, the wiring guide can be solved, but the problem of wiring complexity can be solved. However, since the wiring space is limited, there is a problem that the wiring space is narrow and difficult to cope with the increase in laying. .

In addition, when the wiring guide is a one-stage type, it is difficult to separately lay the information wiring and the power supply wiring, and the problem of noise due to proximity cannot be completely solved, and the upper and lower two stages In the case of the equation, the information wiring and the power supply wiring can be separated in the vertical direction, but there arises a problem that it is difficult to access the wiring laid in the lower stage.
Therefore, an object of the present invention is to solve the problems described above.

  In order to solve the above-described problems, in the present invention, leg projections are provided at the four corners on one side of the rectangular plate, and support members are configured by providing the column projections at the four corners on the other side. The members are arranged at intervals in the vertical and horizontal directions, and the rectangular plate is supported above the floor slab by the leg protrusions, respectively, and for the four corner plates of the adjacent four rectangular plates. The present invention proposes a floor panel support mechanism in which each floor panel is placed on a protrusion to support the floor panel arranged vertically and horizontally.

  In the present invention, it is proposed that the support member is made of an insulator in the above configuration.

In the present invention, the rectangular plate constituting the support member of the floor panel is supported above the floor slab, and the upper space is used as a wiring laying space since the four corner support projections serve as guides. Can do.

  On the other hand, the space above the floor slab between the adjacent support members can be used as a wiring laying space since the leg protrusions of the adjacent support members serve as guides.

  As described above, in the present invention, both the upper space of the rectangular plate member constituting the support member and the upper space of the floor slab between the support members can be used as the wiring laying space, and these laying spaces are in the vertical direction. Since the information wiring is laid in the laying space on one side and the power supply wiring is laid in the laying space on the other side, these wirings can be laid out in an orderly manner. The space can also be easily accessed by removing the floor panel, and management of the space is easy, such as easy removal of the installed wiring. Furthermore, since the information wiring and the power supply wiring can be separated in the vertical direction and the horizontal direction, electromagnetic interference due to the noise from the power supply wiring being superimposed on the information wiring can be avoided.

  Further, in the present invention, both the upper spaces as the facility space have the columnar protrusions or the leg protrusions 3 act as guides, respectively. In comparison, the degree of freedom for wiring is high.

  In the present invention, by configuring the support member with an insulator such as a synthetic resin, it is possible to prevent noise from being superimposed due to electromagnetic induction via the support member.

Next, an embodiment of the present invention will be described with reference to FIGS.
