Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a concrete floorboard for wiring, on which power lines, telephone lines, information communication lines, etc. can be wired.

[Conventional technology]

In recent years, with the rapid development of computers and their peripheral devices, there has been a growing need for intelligent buildings that can accommodate office automation and new information and communication services. As a link to this, there is a need for floorboards that have the flexibility to allow wiring such as telephone lines necessary for office spaces to be taken out from any location. Against this background, floorboards shown in FIGS. 5 and 6 have been known.

In the figure, wiring ducts 2 running vertically and horizontally on the floorboard body 21
A junction box 23 is installed in the floorboard body 21 at a location where the wiring ducts 22 are buried and the wiring ducts 22 intersect. The junction box 23 is composed of a box main body 23A and an outlet 23B which is adjustable in the height direction, and the outlet 23B projects from the floor 21A.

[Problem that the invention seeks to solve]

However, the conventional floorboard has a junction box 23.
Since the outlet 23B protrudes from the floor surface 21A, it is difficult to arrange desks, chairs, etc. in the office room.

It gets in the way of walking. Therefore, junction box 2
The 3B pitch had to be increased, and the wiring had poor flexibility.

[Purpose of the invention]

The present invention has been made to solve the above-mentioned problems, and its purpose is to provide a concrete floor board for wiring with improved wiring flexibility.

[Means for solving problems]

In order to achieve the above object, the present invention comprises a groove provided at a predetermined interval on the upper surface side, a wiring duct buried below the groove, and a plurality of wiring outlets provided in the groove. ,
The wiring outlet is connected to the wiring duct.

[Action of the invention]

According to the present invention, the wiring taken out from the wiring outlet can be placed above the floorboard finishing panel from any position in the groove. Furthermore, since the wiring outlet is provided at the groove position of the floorboard body, the wiring outlet can be made free of protrusions on the upper surface of the finished floorboard panel.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show a concrete floor plate for wiring according to an embodiment of the present invention.

As shown in FIG. 3, reference numeral 1 denotes a precast concrete floor plate body that is made in a factory or on site using a steel formwork A with the chevron portion IA facing downward. As shown in FIGS. 1 and 2, grooves 2A and 2B are formed on the upper surface IB side of the floor plate main body 1.
2C and 2D are formed at predetermined intervals, and these grooves 2A and 2B
, 2C, and 2D, an information communication line duct 3A, a telephone line duct 3B, and a power line duct 3C are buried in the floorboard body 1 so as to be perpendicular to each other below the lines 2C and 2D. The information communication line duct 3A, the telephone line duct 3B, and the power line duct 3C have wiring outlets 4A and 4B, respectively.

4C is provided and continues to the bottoms of the grooves 2C, 2B, and 2A.

In the figure, reference numeral 5 denotes a floor finishing panel provided on the upper surface IB of the floor board main body 1, and since the pitch of the projecting portions IA of the floor board main body 1 supporting this panel is small, the material strength is significantly reduced.

According to the above configuration, the information communication line Without running over the wires, insert the wires x, y, and z taken out from the wire outlets 4A, 4B, and 4C into the grooves 2C, 2B, and 2.
It can be placed on the upper surface of the floorboard finishing panel 5 from any position of A. Also, since the wiring outlets 4C, 4B, and 4A are provided at the positions of the grooves 2A, 2B, and 2G in the floorboard body 1, the wiring outlets 4C, 4B, and 4A are not protruded from the upper surface of the floorboard finishing panel 5. It can be done. In short, the wiring X, Y, and Z can be freely routed in the office room without any obstructive projections appearing on the floor finishing panel 5, and the flexibility of the wiring can be improved.

FIG. 4 shows a modification of the floorboard main body 1, in which a universal support IC is provided on the bottom side of the floorboard main body 1, and a ceiling (not shown) and ceiling wiring etc. are connected to the universal support IC via a suitable hanging device (not shown). equipment is suspended.

In addition, in this example, grooves 2A, 2B, 2C, 2D
The information communication line duct 3A is installed on the floor board body 1 so as to be perpendicular to the
, telephone line duct) 3B, and power line duct 3C are buried. 12A.

It can also be buried obliquely in 2B, 2C, and 2D.

Further, in this embodiment, the information communication line duct 3A, the telephone line duct 3B, and the power line duct 1-3C are provided with wiring outlets 4A, 4B, and 4C, respectively. The present invention is not limited to this, and wiring outlet ports 4A', 4B'', and 40' may be added.

In this case, for example, the information communication line
Since it can be taken out from either 4A' or 4A', the flexibility of wiring is improved.

Furthermore, according to the present invention, flexibility can be ensured with a normal slab thickness without changing the floor height. Therefore, problems such as having to use a floating floor to ensure flexibility are eliminated.

In addition, since precast concrete was used as the structural floor slab, industrialized construction methods are possible.

〔Effect of the invention〕

As described above, according to the present invention, the flexibility of wiring is improved.
