Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a base block for wiring equipment.

[Background technology]

For example, in an office or the like, it is necessary to install many OA devices, and the more OA devices there are, the more wiring there will be.
Conventionally, these wirings were exposed, so
There were problems such as spoiling the aesthetics of the room. Therefore, the above problem was solved by installing a large number of adjusters on a floor such as a concrete foundation, laying a floorboard on top of these adjusters, and passing the wiring through the bottom space of the floorboard. Ta.
However, with this method, it was necessary to install adjusters, adjust their levels, and construct the floor panels, which made the construction work complicated and made it impossible to complete the floor structure in a short period of time. .

To solve this problem, the floor structure (free access floor) shown in FIGS. 3 and 4 has been proposed. This floor structure is called a floor type, and is made of resin material with an open bottom base block (standard type block) 5
A plurality of base blocks 50... are assembled in a lattice arrangement to form one unit unit, and a flexible surface finishing material 51 is adhesively laid over the entire upper surface of these base blocks 50... to form one floor. A unit (panel) is constructed. A plurality of the floor units can be placed on the floor 52 without any fixing means such as adhesive to provide one floor surface. According to this laid-down type floor structure, construction is as simple as just laying it down, and each base block 50 has a gap 5 between each other.
7, the posture can be changed, so there are advantages such as being able to follow the unevenness (unevenness) of the floor 52 as shown in FIG. 4 and absorbing the unevenness well. By the way, in some of these floor units, as shown in FIGS. 5 and 6, a U-shaped base block 53 for wiring is installed using the space where the base block 50 is installed. By attaching an outlet (wiring device) 55 connected to the wiring cord passing under the floor to the installation board 54 that is built in and attached to the base block 53 for wiring, the wiring cord 58 from the OA equipment on the floor is installed. A plug 59 provided at the tip of the opening 5
6 and into this outlet 55.

However, the base block 53 for conventional wiring
As seen in these figures, the upper wall 53a having the opening 56 and the corresponding 2 portions of the upper wall 53a
It was a U-shaped member with side walls 53b, 53b projecting downward from the sides. When this base block 53 is used, as shown by the arrow in FIG. 6, when weight is applied to the floor, the upper wall 53a
The base block 53 is bent and deformed, and the entire base block 53 is also deformed, which may give a feeling of anxiety to those walking on the floor. The base block 53
The end portions of both side walls 53b, 53b are open, and the installation plate 54 is placed between them, but after the unit is installed, the installation plate 54 is designed to prevent air leakage from under the floor. Wire to outlet 55
The width of the installation plate 54 is smaller than the width of the opening 56 because the installation plate 54 is connected to the opening 56 and then installed between the end portions through the opening 56. Thereby, there is a large gap 60, 6 between the installation plate 54 and the both side walls 53b, 53b.
For example, if the wiring cord 58 is housed in the base block 53 so as not to protrude above the floor, it will be routed to the back of the installation plate 54 and connected to a cord clamp or the like provided on the back. The wiring cord 58 is caught on the protrusion 61 and in that state.
If there is a situation where the
8 got caught on the protrusion 61 and was damaged in the past.

[Purpose of the invention]

In view of the above circumstances, it is an object of the present invention to provide a base block for wiring equipment which has a solid under-floor area, which does not cause a feeling of anxiety to those walking on the floor, and which prevents wiring cords from being damaged. shall be.

[Disclosure of the invention]

In order to achieve the above object, the present invention provides one of the base blocks constituting a raised floor in which a plurality of base blocks are laid on an existing floor, at least an upper wall having an opening, and an upper wall having an opening. and opposite side walls protruding downward from both sides of the member, and within the member, wiring equipment is mounted on an installation board provided between the opposing side walls. Wiring from above the floor is connected to the wiring equipment through the opening in the upper wall, and between the both walls there is a wire extending downward from near the opposing edges of the opening. A reinforcing plate protrudes toward the existing floor, and the force applied to the reinforcing plate is borne by the existing floor, and the space formed by at least the reinforcing plate and the installation plate is The subject matter is a base block for wiring equipment, which is characterized by a space that restricts wiring from protruding outside the same space.

Hereinafter, the present invention will be explained in detail with reference to the drawings showing embodiments thereof.

FIGS. 1 and 2 show an embodiment of a base block for wiring equipment according to the invention. As shown in these figures, this base block for wiring equipment is incorporated into one unit of the floor unit, and the unit consists of two types of base blocks 1..., 10... arranged together.
and a surface finishing material 20, which is laid as a single piece on the upper surface thereof, and these constitute one unit of the floor unit. Seven base blocks 1 are prepared as a standard type, and are arranged in a U-shape when viewed from above. Each base block 1 is a common product made of resin material, and its bottom is open. Usually, each base block 1 is provided with legs at four corners, and the spaces between these legs and the internal space thereof serve as wiring passages communicating in all directions. The side surfaces of these base blocks 1... are formed in a tapered shape that becomes narrower toward the bottom, and the gaps 2 formed between the side surfaces allow each base block 1 to
can be displaced along the unevenness of the floor 40. One base block 10 for wiring equipment is installed in the space for two base blocks formed by the base blocks 1. The base block 10 is made of a resin material and has four tapered side surfaces similar to the base block 1 described above. This base block 10 is
It is U-shaped and includes an upper wall 12 having an opening 11, and both side walls 13, 13 that protrude downward from both sides of the upper wall 12 and are opposed to each other. It is designed to be installed on the floor 40 so as to face. An installation plate 14 is attached to a portion of the upper wall 12 corresponding to between the side walls 13, 13 so as to be located near the opening 11, and an outlet 15, which is a wiring device, is attached to the installation plate 14. The insertion port 15a faces slightly toward the opening 11 in the horizontal direction, and the plug 31 of the wiring cord 30 connected to the OA equipment installed on the floor is inserted into the insertion port 15a. It is adapted to be inserted through the opening 11. The surface finishing material 20 is made of a flexible material such as carpet, and one sheet of the surface finishing material 20 is laid and bonded so as to cover the upper surface formed by the base blocks 1..., 10....

By the way, the base block 10 for wiring equipment
Between the both side walls 13, 13, there is a reinforcing plate 1 that protrudes downward from both side edges of the upper wall sandwiching the opening 11, and has a lower end resting on the floor base 40.
6 and 16 are arranged facing each other. These reinforcing plates 16, 16 correspond to each other at the same interval as the width of the opening 11, and in the horizontal direction, are shorter than the side wall 13 but have the same length as the side part of the opening 11, or , formed a little longer than that. The installation plate 14 is arranged with a slight gap 17, 17 between the ends of both of the reinforcing plates 16, 16, and each gap 17 is connected to the wiring cord 30.
The dimensions are such that it will not fit through. of course,
The side walls 13, 13 and the installation plate 14 may be brought into contact with each other so that there is no gap. Among the side portions forming the opening 11, an auxiliary plate 18 having an L-shaped bent shape and including a vertical plate and a bottom plate is attached to the bottom surface of the side facing the installation plate 14. The auxiliary plate 18 is configured such that its vertical plate faces the installation plate 14 and its bottom plate extends from the bottom of one end of the side walls 13, 13 to the bottom of the other end and comes into contact with the lower end of the installation plate 14. It's summery. The upper opening space 19 formed by the installation plate 14, the side walls 13, 13, and the auxiliary plate 18 is a space into which the wiring cord 30 is inserted, and the wiring cord 30 protrudes outside the space 19. It seems like there is no such thing.

As described above, the base block for wiring equipment according to the present invention protrudes downward from the vicinity of the edge of the upper wall sandwiching the opening between the two side walls, and the lower end portion is supported on the subfloor. Since the reinforcing plates are placed opposite each other, the weight of the person walking on the floor is
Even if an action is applied to the upper wall as shown by the arrow in the figure, the upper wall will not bend easily, and this will suppress the bending of the entire base block, preventing those walking on the floor from sinking and feeling uneasy. do not have. Moreover, since the space formed by at least the reinforcing plate and the installation plate is a space that restricts the wiring from protruding outside the space, for example, If the wiring cord is placed inside the block, it will not run around to the back of the installation board, and this will prevent the wiring cord from getting caught in the protrusion such as a cord clamp provided on the back and being pulled. This eliminates the possibility of damage caused by getting caught on the protrusion.

Note that the base block for wiring equipment may have the bottoms of both side walls connected to each other by another wall. Each of the base blocks need not be quadrangular, but may adopt other geometric shapes such as hexagons. The floor structure of the above embodiment was constructed using a unit type structure, but
For example, the entire floor can only be constructed by later laying a surfacing material on top of previously arranged base blocks. In this case, after the base blocks have been laid over the entire floor, the surface finishing material can be applied over the entire floor, or over a certain area (not necessarily limited to the unit area of the unit). It can be as wide as possible. The surface finishing material does not need to be fixed to the base block by adhesive or the like.

〔Effect of the invention〕

Since the base block for wiring equipment according to the present invention is constructed as described above, the base block is solid under the floor and there is no risk of causing anxiety to those walking on the floor, and furthermore, the base block for wiring equipment does not get caught on the protrusions. It is no longer damaged.
