Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a so-called double-floor structure in which floor panels are arranged on an upper surface of concrete floor in an existing office room with appropriate gaps for wiring. The present invention relates to a structure of a leg device that supports a floor panel for a vehicle.

[Conventional technology]

In recent computer rooms and offices, the number of wires for electronic devices has increased remarkably, so floor panels are laid on the concrete floor top surface of existing rooms with appropriate wiring gaps, so-called double floors. (Lifting) is configured.

In this case, as a conventional technique for pulling out the wiring cord arranged below the floor panel, as disclosed in Japanese Patent Publication No. 61-34545 of the prior art, the side edge length of the floor panel is long. A notch hole is bored in the vertical direction in the middle of the direction, and the wiring cord is inserted vertically through the notch hole. On the other hand, it is usual to simply attach legs whose height can be adjusted to the lower corners of the floor panel.

[Problems to be solved by the invention] However, the wiring cord is not always inserted into this cutout hole, and when not in use, dust may drop down from the space of the cutout hole. Also, when the upper surface of the floor panel is covered with a cover body such as a carpet cut into a shape that is substantially the same as the plane shape of the floor panel, the mounting body is not formed because of the cavity at the cutout hole. There was a problem that it would be unnaturally depressed.

This problem occurs not only when the cutout holes are provided at the corners of the floor panel, but also because the corners have legs, the processing becomes more complicated.

The present invention solves the above-mentioned problems that could not be conventionally solved by devising the structure of the legs that support the corners of the floor panel.

[Means for Solving the Problems]

Therefore, according to the present invention, the top plate of the corner portion of the floor panel to be arranged on the floor upper surface with appropriate vertical gaps is appropriately cut to form the notch, while the space formed on the lower surface side of the corner portion. A leg for supporting the floor panel is fitted therein so that lateral movement is restricted, and a wiring cord insertion space is formed below the upper plate of the leg, and the upper plate has A corner piece protruding outward from the cutout portion is connected so as to be bent upward.

[Operation and effect of device]

The leg in the present invention is inserted into the space in the corner of the floor panel so as to support the top plate at the corner, and the wiring cord is provided between the floor panel supported by the leg and the floor upper surface. There is a vertical gap that can be wired.

A wiring cord insertion space is formed below the upper plate of the leg body, and a corner piece protruding outward from the cutout portion is connected to the upper plate so as to be bent upward. Therefore, it is extremely easy to pull the wiring cord below the floor panel upward from the insertion space in the leg body through the notch at the corner of the floor panel through the opening below the corner piece bent upward.

Further, when the corner piece connected to the upper plate of the leg is laid down in a substantially horizontal state, the corner piece comes to project outward from the cutout portion, so that it is formed at the corner portion of the floor panel. In addition, there is no dent in the flat part of the notch or a void communicating with the floor surface, and it is possible to eliminate the condition that the corner piece is standing up, and there is no accident that the walking person is injured.

〔Example〕

Next, an example will be described. FIG. 1 is a perspective view when a plurality of floor panels 1 each having an isosceles triangular shape in plan view are combined and laid in a rectangular shape in plan view. Each floor panel 1 is shown in FIG. As shown in FIG. 3, side plates 3 and 3 are formed by bending the side edges of a top plate 2 made of a metal plate having an isosceles triangular shape in plan view downward, and the bottom surface of the top plate 2 is made of a noncombustible material. A lightweight and highly rigid reinforcing member 4 such as a honeycomb member is stretched, and the lower surface thereof is covered with a holding frame 5 having an upwardly U-shaped cross section.

Spaces 8 and 9 into which a main leg body 6 and a sub leg body 7 to be described later can be fitted in the 90-degree corner portion and the two 45-degree corner portions in a plan view of the floor panel 1 in a state in which they are restricted from lateral movement. , 9 are molded.

Further, a notch 10 is formed by appropriately notching the top plate 2 and the left and right side plates 3, 3 at the 90-degree corner of the floor panel 1.

The main leg body 6 shown in FIG. 4 includes a pair of left and right foot plates 11, 11 and an upper plate 12 integrally formed at the upper ends of the foot plates 11, 11.
The pair of left and right foot plates 11, 11 of the main leg body 6 extend in the direction of 90 degrees with respect to each other in plan view, and the upper plate 12 of the main leg body 6 has The corner piece 13 having a triangular shape in plan view, which is placed over the upper ends of the pair of left and right foot plates 11, 11, has a thin connecting portion (hinge portion).
It is connected via 14 so as to be bendable upward.

Therefore, in the state where the corner piece 13 is bent upward, the lower side of the corner piece 13 and the pair of left and right foot plates 11, 1 are.
An insertion space in which the wiring cord 15 can be inserted is formed between 1 and the upper plate 12 (see FIG. 7).

Further, a vertically long cut groove 16 is formed on the approaching side of the pair of left and right foot plates 11, 11 so that the wiring cord 15 can be easily inserted. The cut groove 16 is at least the corner piece 13. It may be formed only at a position close to.

Reference numerals 17 and 17 denote upper and lower longitudinal fitting groove-like engagements formed on spacer members 18 and 18 having a thickness dimension (H) protruding from the outer surfaces of the pair of left and right foot plates 11 and 11 of the main leg body 6. It is a means.

On the other hand, each sub-leg body 7 includes a pair of left and right foot plates 19, 1 in plan view.
9 is a hollow member having an apex angle of 45 degrees and integrally connecting upper ends of both foot plates 19 and 19 with an upper plate 20.
On the outer surface of the foot plate 19 on the side of the floor panel 1 that abuts the side plates 3 extending in the 90-degree direction to each other, a protrusion engaging means that can be fitted in the engaging means 17 of the main leg 6 from above and below. 21 is formed.

Therefore, a pair of left and right auxiliary leg bodies 7, 7 is required for one floor panel 1. That is, the engaging means 21
Is to prepare the auxiliary leg body 7 protruding to the right side and the auxiliary leg body 7 to which the engaging means 21 protrudes to the left side.

In this configuration, as shown in FIG. 1, if a pair of floor panels 1 and 1 are arranged so that their diagonals face each other,
The floor panels 1 and 1 have a square shape in a plan view, and the main leg body 6 is placed in the space 8 at the 90-degree corner of each floor panel 1.
The sub-legs 7, 7 are fitted into the pair of spaces 9 of 45 degrees, and as shown in FIG. 6, the sub-legs are fitted to the pair of left and right engaging means 17, 17 of the main leg 6. If the engaging means 21, 21 of the bodies 7, 7 are fitted and engaged, one floor panel 1
Main leg 6 at the 90-degree corner and sub-leg 7 at the 45-degree corner of floor panel 1 adjacent thereto.
Since the lateral movement is regulated in a state of contacting the inner surfaces of the side plates 3 and 3 of each floor panel, the floor panels 1 and 1 adjacent to each other engage with each other without lateral displacement. It cannot be laterally displaced and can be arranged on the floor 22 in an orderly manner without rattling.

Then, the lengthwise gap of (H-2t) is obtained by subtracting twice the thickness dimension (t) of the side plate 3 in each floor panel 1 from the thickness dimension (H) of the pair of left and right spacers 18, 18 of the main leg body 6. 23 can be formed in a cross shape in a plan view.

Since the thickness dimension of the main leg body 6 and the sub leg body 7 is made larger than the thickness dimension of the floor panel 1, the wiring cord 15 can be inserted between the floor surface 22 and the bottom surface of each floor panel 1. A gap is created, and in order to pull out the wiring cord 15 from the pair of left and right foot plates 11, 11 of the main leg 6 toward the upper surface of the floor panel 1, the corner piece 13 is bent as shown by the one-dot chain line in FIG. The wiring cord 15 may be pulled out from the insertion space in the main leg body 6 through the opening formed.

Reference numeral 24 is a flexible quadrangular surface mount body such as a carpet laid on the upper surfaces of the pair of floor panels 1, 1, and the side edges of the cover body 24 form a gap over the upper surface of the longitudinal gap 23. It covers without.

The corner piece 13 is bent upward so that the wiring cord 15
When pulling out, the 90-degree corner of the cover 24 may be slightly lifted up.

Therefore, in the conventional technique, since the wiring cord is passed upward from the cutout hole formed in the middle portion of the longitudinal side edge of the floor panel, the wiring cord must be cut off at the side edge of the covering body such as the carpet at the location. There was also a problem that the side edges of the cover were raised over a wide area to push the carpet away.However, when the cutouts are provided at the corners of the floor panel as in the present invention, the side edges of the cutouts are placed on the upper side. It is possible to reduce the range of curling up of the corners of the mounted body such as carpet.

Further, since the corner piece 13 projects outward from the cutout portion 10 at the 90-degree corner, and the top plate 2 of the floor panel 1 is not above the corner piece 13, the corner piece 1
If 3 is held in a horizontal state, the wiring cord 15 cannot be inserted, that is, the opening that leads to the lower side of the main leg 6 can be closed when not in use, and the unnatural fall of the outer cover 24 can be prevented. You can do it.

If the thickness of the corner piece 13 is set larger than the thickness of the upper plate 12 of the main leg 6 by the thickness of the top plate 2, the corner piece 13 will be in a horizontal state. Since the upper surface and the upper surface of the top plate 2 are flush with each other, it is possible to prevent an unexpected accident in which a person stumbles due to a fall of a corner of the cover member 24.

It is needless to say that the engaging means 17 of the main leg 6 and the engaging means 21 of the sub leg 7 may be configured so that the concavo-convex relationship is opposite to that shown in the drawing.

FIG. 8 shows a second embodiment of the present invention, in which the floor panel 25 has a rectangular shape in a plan view, and four corners thereof are appropriately cut out to form the cutout portions 26, while the above-mentioned view of 90 degrees in a plan view is formed. At each corner, a pair of left and right foot plates 1 having substantially the same shape as the main leg body 6 is formed.
A leg 27 having a U-shaped cross section, which is composed of 1, 11 and the upper plate 12, is fitted. The corner piece 13 protruding from the upper plate 12 toward the cutout portion 26 is formed by the pair of left and right foot plates 1.
The corner pieces 13 are connected to each other so as to be bendable upward via thin connecting portions (hinge portions) 14 in a triangular shape in a plan view which is placed over the upper ends of the reference numerals 1 and 11.

In the state where the corner piece 13 is bent upward, an insertion space in which the wiring cord 15 can be inserted is formed between the lower side of the corner piece 13 and the pair of left and right foot plates 11, 11 and the upper plate 12.

Further, a vertically long cut groove 16 is formed on the approaching side of the pair of left and right foot plates 11, 11 so that the wiring cord 15 can be easily inserted. The cut groove 16 is at least the corner piece 13. It may be formed only at a position close to.

In addition, the pair of left and right foot plates 1 of the leg body 27 in this embodiment
On the outer surface of one foot plate 11 of the first and the first spacers 11, spacer members 18, 18 having the same thickness dimension (H) as in the first embodiment.
The upper and lower longitudinal engaging groove-shaped engaging means 28 is formed on the outer surface of the other foot plate 11.
Are provided respectively.

Therefore, also in this embodiment, as in the case of the above-described embodiment, the legs 2 fitted into the corner portions of the floor panels 25, 25 adjacent to each other.
One of the engagement means 28 of 7, 7 and the other engagement means 29 are engaged in a non-removable manner, and the adjacent floor panels 25, 25 are
It can be arranged neatly without lateral displacement.

Reference numeral 30 is a lower rail for erected a partition or wall panel 31 by utilizing the gap between the adjacent floor panels 1 or 25, and a support bolt 33 to which a board 32 such as a plate is attached at the lower end. The nut 34 is inserted into the gap, and the nut 34 is fastened so as to sandwich the pair of left and right floor panels 1 or 25 and the cover body 24 between the upper surface of the board 32 and the lower rail 30 having a downward U-shaped cross section (first). (See FIGS. 9 and 10).

Further, as shown in FIG. 11, the bolt 35 and the nut 3
