Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a floor panel for a double floor used for constructing a free access floor, and in particular, a power cable, a communication cable, etc. wired in an underfloor space. The present invention relates to a floor panel for a double floor provided with a cable passage hole for leading out to the equipment installed on the floor so that the equipment can be led out onto the floor.

<Prior Art and Its Problems> In this type of conventional floor panel, a cable passage hole is formed in the center of the panel body so as not to impair the strength of the floor panel. Therefore, when it is necessary to separate the cable from the cable through hole of the floor panel when changing the layout of the equipment installed on the floor panel, the cable cannot be separated from the cable through hole unless it is removed from the equipment each time. , There was a problem that was very troublesome.

However, if the cable through hole is formed by cutting out the peripheral edge of the panel body, the strength of the floor panel will be significantly reduced.

<Problems to be solved by the present invention> The present invention has been made in view of the above-mentioned conventional problems, and even when the cable is connected to the devices installed on the floor panel, the cable can be routed through the cable. It is intended to provide a floor panel for a double floor, which can be easily inserted and separated into a hole and at the same time can maintain the strength substantially equal to that of a normal floor panel having no cable passage hole.

<Means for Solving the Problem> A floor panel for a double floor of the present invention which achieves such an object is configured such that a plurality of cables are inserted in the vicinity of a corner portion of a panel body mounted on a pedestal of a supporting leg. The cable introduction hole is opened in a large area, and the cable introduction port opened from the cable passage hole to the corner of the panel body is cut into a width approximately the same as the outer diameter of the cable. It is what

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

The panel body 1 is formed into a flat square shape of a desired size by aluminum die casting or the like, and is mounted on the pedestal 3a of the support leg 3 standingly arranged on the foundation floor surface 2 of the building in the same manner as the other floor panels 4. The double-floor surface (free access floor) is formed by supporting the corner portion 1a.

A cable through hole 5 is formed near the corner 1a of the panel body 1 and the cable through hole 5 is formed.
From this, a cable introduction outlet 6 that is opened toward the corner 1a of the panel body 1 is formed by cutting.

The cable through hole 5 is for leading out the cable 8 wired in the underfloor space 7 onto the floor panel so as to be connected to devices installed on the floor panel, and near the corner 1a of the panel body 1, An opening is formed in a desired shape such as a square shape or a round shape with an opening area capable of inserting and housing a plurality of cables 8.

The cable inlet / outlet 6 connects the cable 8 to the cable through hole 5
It is to be introduced into and taken out of the cable 8 and is formed with a slit having a width substantially equal to the outer diameter of the cable 8 so as to be pulled out from the cable through hole 5 toward the corner portion 1a of the panel body 1. That is, the cable inlet / outlet 6 introduces / draws the cable 8 into / from the cable through hole 5 and at the same time prevents the strength of the floor panel from being impaired by forming the cable inlet / outlet 6. Is formed to have a narrow width almost equal to the outer diameter (thickness) of the support leg 3, and is formed toward the corner portion 1a of the panel body 1 which is placed and supported on the pedestal 3a of the support leg 3, and the opening 7a is formed in the panel body. It is opened toward the first corner portion 1a.

Thus, when inserting or separating the cables 8 routed in the underfloor space 7 into the cable through holes 5, the panel body 1 is removed from the pedestal 3a of the support leg 3 and the cables 8 are introduced one by one. Introduced or led out through exit 6,
Then, the panel body 1 is placed on the pedestal 3a of the support leg 3. Then, the opening 6a of the cable inlet / outlet 6 is closed by the end face of the other adjacent floor panel 4 or the pedestal head 3c of the support leg 3.

4 and 5 show another embodiment of the present invention, in which each cable 8 inserted and accommodated in the cable passage hole 5 is prevented from coming into contact with the rim of the cable passage hole 5 and being damaged. A bush 9 is detachably attached to the rim of the through hole 5.

The bush 9 is made of a flexible material such as a rubber material or a resin material, and is formed in a bottomed cylindrical shape having a thick locking brim 9a formed in substantially the same shape as the cable passage hole 5, and
Cut from the bottom wall 9b to the cylinder wall 9c and the locking flange 9a.
9d is formed so that the cable 8 can be introduced and led out from the slit 9d.

<Effect of the Invention> According to the floor panel for a double floor of the present invention, the following effects are obtained.

Since the cable can be introduced into and pulled out from the cable introduction hole through the cable introduction outlet, even if the cable is still connected to the equipment installed on the floor panel, the cable can be easily inserted into the cable passage hole. It can be separated.

The cable inlet / outlet for introducing and extracting the cable to / from the cable through hole is formed with a width that is almost the same as the outer diameter of the cable, and is cut toward the corner of the panel body that is placed and supported on the pedestal of the support leg. Since it was made to form, there is almost no loss of strength as a floor panel,
It is possible to maintain the same strength as a normal floor panel without a cable passage hole.

Since the cable inlet / outlet is formed to have almost the same width as the outer diameter of the cable, the cable will not be inadvertently pulled out from the cable through hole after being inserted and housed in the cable through hole. Since it is blocked by the floor panel or the pedestal head of the support leg, the cable does not interfere when laying the floor panel,
The cable will not come out of the cable passage hole without using a special member.
