CONSTITUTION:Multiple sets of branch trays 1 are arranged in parallel at fixed intervals on a floor surface P, and tray covers 5 are installed on the branch trays 1. A trunk tray 2 separated into a power line wiring space S3a and a signal line wiring space S3b by a separator 11 is arranged at one end of the branch trays 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a free access floor (double-floor type floor) which can be used in office buildings and the like in which electric wiring is complicated with the spread of various OA equipment.

[0002]

2. Description of the Related Art Conventionally, this type of free access floor has a structure in which a floor plate is laid on a four-point support base such as support legs or block pieces. That is, allocation and marking are performed on the floor surface, and a plurality of supporting legs or block pieces etc. are installed on the entire surface of the floor based on the allocated ink, and the four corners of the plurality of floor plates are installed on these floor surfaces. It is designed to be supported by legs or block pieces.

On the conventional free access floor,
There is nothing between the floor and the floor plate.

[0004]

However, in the above-mentioned conventional free access floor, the allocation and marking out on the floor surface must be performed in the vertical and horizontal directions, which is a problem that this work is very troublesome. Was.

Further, in the above-mentioned conventional free access floor, since the four corners of the floor plate are only supported by the supporting legs or block pieces, the floor plate is inferior in load resistance and the floor plate rattles. However, it has a problem of poor walking ability.

Further, in the above conventional free access floor, the main line space is not separated at all, and the main line space and the branch line space are not particularly separated.
Since it is difficult to disperse and wire strong electric wires such as electric power lines and weak electric wires such as communication lines, there has been a problem that accidental contact of both lines often occurs.

Moreover, the above-mentioned conventional free access floor has a problem that the strength and soundproofing of the floor are poor depending on the use.

In view of the above, the present invention eliminates the need for allocation and marking on the floor surface, supports both entire surfaces of the floor plate, and separates the trunk space itself, and also the trunk space. It is an object of the present invention to solve the problems of the above-mentioned conventional free access floor by separating the space between the branch line and the branch line and improving the strength and soundproofing of the floor.

[0009]

Therefore, in the free access floor of the present invention, the branch line trays 1 are arranged in parallel on the floor surface P, and a plurality of sets of the vertically arranged branch line trays 1 are arranged in parallel on the floor surface P at regular intervals. Then, a tray cover 5 is installed on top of these branch line trays 1, and a separator 11 is provided at one end of these branch line trays 1 to provide a high-voltage wiring space S3a.
And a separate main line tray 2 is attached to the light electric wiring space S3b.

In the branch line tray 1, a separator 9 is used for the high-current wiring space S1a and the low-current wiring space S.
It can be separated into 1b.

Further, the wiring space S2 can be formed by bridging the floor plate F between the receiving seats 6, 6 of the branch line trays 1, 1 arranged in parallel.

In addition, the mortar M may be placed between the branch line trays 1 and 1 arranged in parallel.

Furthermore, the branch line trays 1 arranged in parallel,
The floor plate F is hung between the receiving seats 6 of 6 and the sand Sa or the peach ball Sb is provided below the floor plate F.
Can be installed.

[0014]

The free access floor of the present invention, having the above-mentioned means, has the following operation.

First, when the branch line trays 1 are arranged in tandem,
Since the branch line tray 1 itself serves as a ruler, vertical layout and marking are unnecessary. Further, in the case where the floor plate F is stretched between the catches 6 and 6 of the branch line trays 1 and 1, when the branch line trays 1 arranged in parallel are arranged side by side, the floor plate F serves as a ruler, so that the horizontal layout is possible. And stake out is also unnecessary.

Further, both sides of the floor plate F are supported between the receiving seats 6 provided on the branch line trays 1 and 1 facing each other, so that the floor plate F is stable and the branch line trays 1,
1 is laid.

The main line tray 2 is separated into a high-voltage wiring space 3a and a low-voltage wiring space 3b, and the branch line tray 1 can also be separated into a high-voltage wiring space 1a and a low-voltage wiring space 1b. The strong electric wire and the weak electric wire such as a communication wire are dispersed and easy to be wired.

Further, if the wiring space S2 is formed between the branch line trays 1 and 1, the wiring function of the branch line is excellent, and if the mortar M is placed between the branch line trays 1 and 1, the floor strength is high. If the sand Sa or the beach ball Sb is laid under the floor plate F, the floor will have excellent soundproofing.

[0019]

[Embodiment] The free access floor of the present invention will be described below.
A detailed description will be given based on the drawings shown as examples.

FIG. 1 is a plan view showing a free access floor of the present invention, in which branch line trays 1 are vertically arranged on a floor surface P, and a plurality of sets of vertically arranged branch line trays 1 can be laid on a floor plate F at regular intervals. Is placed in parallel with the floor surface P. Further, a trunk line tray 2 is attached to one end of each branch line tray 1. Further, the branch line tray 1 and the main line tray 2 are connected via a branch tee 3.

As shown in FIG. 2, the branch line tray 1 has a wiring space S1 inside and is anchored to the floor P by an anchor bolt, or is not shown but is bonded to the floor P. By doing so, it is tandem on the floor surface P. The tray cover 5 is covered on the upper portion of the branch line tray 1 with a cushion member 4 interposed therebetween, and the branch line tray 1
Seats 6 are provided on both shoulders.

Then, the floor plates F are laid between the branch line trays 1 and 1 by interposing cushioning members 4 on the receiving seats 6 of the branch line trays 1 arranged in parallel to each other, and the floor plates F are laid between the branch line trays 1 and 1. A wiring space S2 is formed.

Further, the branch line tray 1 is formed with a passage opening 7 at an appropriate position on the side portion thereof, and the wiring space S1,

The intervals between the branch line trays 1 and 1 arranged in parallel are 60 cm, 90, which is a divisor of the module size (360 cm x 360 cm) of the building.
If the height is cm or 120 cm, the branch line tray 1 can be regularly arranged within the module size.

As shown in FIG. 9, the main line tray 2 is divided into a high-voltage wiring space S3a and a low-voltage wiring space S3b by a separator 11, and may be anchor bolted to the floor surface P or the floor surface P. It is laid on the floor surface P by being bonded to. A tray cover 12 is installed on the main line tray 2 with a cushion material 4 interposed. Then, as shown in FIG. 10, an outlet box 13 is attached to an appropriate portion of the main line tray 2 to connect a lead pipe 14 for a strong electric wire and a lead pipe 15 for a weak electric wire from the EPS.

The branch tee 3 communicates with the high-voltage wiring space 3a or the low-voltage wiring space 3b of the main tray 2, and the high-voltage wiring or the low-voltage wiring arranged in the high-voltage wiring space 3a, 3b is connected to the branch line tray. It is designed so that it can be selectively withdrawn to 1.

The free access floor of the present invention is completed by laying tile carpets K on the upper surfaces of the tray cover 5 of the branch line tray 1, the tray cover 12 of the main line tray 2, and the floor plate F. It will be what you did.
