Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a structure of a double floor constructed by laying a panel having legs on the back on a floor base for the purpose of wiring under the floor and the like.

[Prior Art] In recent years, especially in offices and the like, many electric devices such as various OA devices have been introduced. The installation or wiring of these electrical devices is usually performed separately from the interior of the building, and the wiring is most simply performed by cables arranged on the floor of the building. However, arranging a large number of cables on the floor is not only inferior in appearance but also in safety, and is against the realization of a comfortable office space or living space which is increasingly demanded in recent years.

Therefore, the floor has a double structure, and these cables are arranged below the floor. Conventionally, as a structure of this double floor, there is known a structure in which a plurality of panels each having a plurality of legs formed on a back surface at predetermined intervals are laid on a floor base.

By the way, the specification of the strength of the panel on the double floor as described above is usually based on the loading load calculated from the largest weight per mounting area among the equipment etc. mounted on the floor. Panels that are set to withstand such pressure and have such strength are used for the entire floor surface to form a double floor.

"Problem to be solved by the invention" The conventional double floor structure has the following problems.

That is, particularly when a heavy object is placed on the floor, expensive panels having high strength are laid all over the floor, so that the cost for forming the double floor is very expensive. Had become something.

The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a double-floor structure that can be easily configured with minimum cost.

"Means for solving the problem" The structure of the double floor of the present invention is a double floor structure in which a plurality of panels each having a plurality of legs formed on the back surface at predetermined intervals are laid on a floor base. The panels are composed of a plurality of types of panels formed into the same shape and the same size with resins having different strengths, and are characterized by being color-coded according to the strengths.

[Operation] In the double floor structure of the present invention, a plurality of panels having different strengths are laid to form a double floor.
For this reason, a high-strength panel can be laid only at a position where a heavy object is placed, thereby eliminating a place where the specification of the panel strength becomes excessive quality and reducing the material cost of the panel. Can be minimized.

The panels are color-coded according to their strength. Therefore, if the panel is laid in a predetermined position while identifying the intensity based on the color, the panel to be laid is not mistaken. Also, after the double floor is constructed, the strength of each panel constituting the floor can be confirmed by this color,
It is possible to prevent a heavy object exceeding the strength of this panel from being erroneously placed on a low-strength panel, and to see at a glance whether the panel needs to be changed due to a change in the position of the heavy object. Can be determined.

Further, since panels having different strengths are formed in the same shape and the same size, panels having different strengths can be manufactured on the same manufacturing line. In other words, it is possible to standardize a mold for panel molding and the like,
Equipment costs can be reduced.

An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a perspective view showing the entire structure of a double floor, and FIG.
The figure is an X sectional view of FIG. In the figure, reference numeral 1 denotes a floor substrate such as a slab. A plurality of panels 2a and 2b are laid on the floor substrate 1.

The panel 2a is made of a synthetic resin such as PP (polypropylene), and has a plurality of ribs on the back surface as shown in FIGS.
A panel body 3 having a square 3a formed thereon, and legs 4, 4 provided on the periphery and the center of the back surface of the panel body 3, respectively.
5 and 6, a plurality of arc-shaped slits 7 are formed on the upper surface, and the legs 4, 5, and 6 have convex portions of rubber seats 10, 11 described later.
The recesses 8 to be fitted to 12 are respectively formed.

The panel 2b has the same shape and the same dimensions as the panel 2a, and has a higher strength than the panel 2a by changing the material to fiber reinforced PP (polypropylene), and has a different color from the panel 2a. It was like that.
In the case of the present embodiment, the load that one panel can withstand is about 300 kg for the panel 2a and about 1500 kg for the panel 2b.

As shown in FIG. 2, these panels 2a and 2b are spread over the floor substrate 1 via rubber seats 10 and 11 on the upper surface of a sheet 9 laid on the upper surface of the floor substrate 1. here,
The sheet 9 is made of foamed polyethylene or the like, absorbs minute irregularities of the floor substrate 1, and is adhered to the floor substrate 1. The rubber seats 10 and 11 are made of an elastic resin,
As shown in FIG. 5 to FIG. 8, the upper surface has a predetermined number of convex portions 12, and the convex portions 12 are fitted into the concave portions 8 of the legs, respectively, so as to be provided between the sheet 9 and the legs of the panel 2. It is interposed. That is, the rubber seat 10 has one convex portion 12 and is interposed on the lower surfaces of the legs 4 and 6, and the rubber seat 11 has four convex portions 12 at a predetermined interval. The protrusions 12 are fitted to the four legs 5 and are interposed.

Among these panels 2a and 2b, panel 2 having high strength
b is used only at the position where the heavy object is placed (in the case of this embodiment, the position indicated by reference numerals A and B).

On the upper surface of the panel 2, a floor finishing material 13 such as a tile or a carpet is laid and adhered.

According to the floor structure having the above-described configuration, cables and the like can be arranged in the space 14 formed below the panel 2 to perform underfloor wiring. In addition, a heavy object having a load per panel of about 1500 kg can be installed at positions indicated by reference signs A and B on the floor surface.

The floor structure as described above can be easily constructed by the following procedure.

First, after laying and bonding the sheet 9 on the floor substrate 1, the legs 9
Panels 2a, 2b with rubber seats 10 attached to 4, 6 and rubber seats for legs 5
By attaching 11 to each other, they are placed on the sheet 9 via a rubber seat while being connected to each other, and are spread.

At this time, the panels 2a and 2b are identified based on the difference in color, and are laid at predetermined positions.

Here, when it is desired to set the laying position (assignment) of the panel 2 and lay the panel 2 so that the legs of the panel 2 do not interfere with the laying route of the cable for the floor wiring, etc. Draw a reference line on the screen and easily perform the operation.

Then, if the floor finishing material 13 is laid on the upper surface of the panel 2 thus laid and bonded, the construction is completed.

According to the double floor structure of the present embodiment, the following effects can be obtained.

That is, the high-strength panel 2b is laid only at the position where the heavy object is placed, and the low-strength and inexpensive panel 2a is laid at the position where the heavy object is not placed.
There are no places where the specification of the strength of the panel becomes excessive quality, and the material cost of the panel is minimized. For this reason, the cost of constructing a double floor is greatly reduced.

The panels are color-coded according to their strength. Therefore, if the panel is laid in a predetermined position while identifying the intensity based on the color, the panel to be laid is not mistaken. Also, after the double floor is constructed, the strength of each panel constituting the floor can be confirmed by this color,
It is possible to prevent accidentally placing a heavy object exceeding the strength of this panel on a low-strength panel, and to determine at a glance whether the panel needs to be changed due to a change in the position of the heavy object. Can be determined.

In addition, since there is no need to modify the walls, floor foundations, etc. of the building at the time of construction, the floor of the existing building can be easily changed to a double floor.

Further, since the panel 2 can be easily partially removed in a state where the floor finishing material 13 has been peeled off, and can be easily attached again as it was, the wiring in the floor can be redone as many times as possible, and wiring change and cable connection can be performed. Addition is very easy.

Further, since the panel 2 is placed on the floor base 1 via the elastic rubber seats 10 and 11 and the sheet 9 made of foamed polyethylene, the "squeaking sound" and the "sound of the floor" which are often present in a double floor. And the like, and the impact during walking is alleviated, resulting in a soft walking feeling floor.

Further, since the panel 2 is laid on the sheet 9 laid on the floor substrate 1, this sheet 9
It is easy to draw a reference line on the panel 2 and to use the reference line to accurately spread the panel 2 at a preset position.

In the case of the present embodiment, the panels are square, but are not limited to this, and may be of any shape as long as they can be laid without gaps between adjacent panels. It may be rectangular. Also,
The size is not limited to a fixed size, and for example, two types of panels, large and small, each having a side dimension of 1: 2 may be used.

"Effects of the Invention" The structure of the double floor of the present invention has the following effects.

That is, since a plurality of panels having different strengths are laid to form a double floor, a high-strength panel can be laid only at a position where a heavy object is placed, This eliminates the places where the specification of the strength of the panel becomes excessive quality, thereby minimizing the material cost of the panel and reducing the cost of constructing the double floor.

The panels are color-coded according to their strength. Therefore, if the panel is laid in a predetermined position while identifying the intensity based on the color, the panel to be laid is not mistaken. Also, after the double floor is constructed, the strength of each panel constituting the floor can be confirmed by this color,
It is possible to prevent a heavy object exceeding the strength of this panel from being erroneously placed on a low-strength panel, and to see at a glance whether the panel needs to be changed due to a change in the position of the heavy object. Can be determined.

Further, since panels having different strengths are formed in the same shape and the same size, panels having different strengths can be manufactured on the same manufacturing line. In other words, it is possible to standardize a mold for panel molding and the like,
Equipment costs can be reduced.
