[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double floor panel for forming a double floor for wiring under the floor, and more particularly to a double floor formed by connecting a plurality of panel bodies. For panels.

[0002]

2. Description of the Related Art In recent years, various types of O are especially used in offices and the like.
Many electric appliances such as A appliances are 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 unsightly but also insecure, and is contrary to the realization of a comfortable office space or living space which has been increasingly demanded in recent years. Therefore, the floor has a double structure, and these cables are arranged below the floor.

[0003] As described in Japanese Utility Model Laid-Open No. 3-66347, a double-floor structure having a plurality of legs formed on a back surface at predetermined intervals is used as a double floor structure covering a relatively large area. There is known a configuration in which the components are connected to each other by a connecting portion having a property. In this case, a portion that extends horizontally from the side wall of the panel is formed, and the ends are connected by a U-shaped portion.

[0004]

However, such a conventional panel requires a space between the side walls by the length of the horizontal portion and the length of the U-shaped portion. The dimensions are reduced and the strength is reduced, there are many bent parts in one connection part, these are likely to cause cracks, the structure is complicated and molding is difficult,
There was a problem that the cost of the molding die also became high.

The present invention has been made in view of the above-mentioned conventional circumstances, and provides a structure in which panel bodies are firmly and flexibly connected with each other, and no space is required between the panel bodies and molding is easy. It is intended to provide a panel for a double floor.

[0006]

The double-floor panel of the present invention comprises a plurality of panel members having legs on the back surface of a flat plate portion and connected to each other by a flexible connecting portion. a double floor panel, configured from the connecting portion, a base portion which is formed perpendicular to the flat plate portion to the peripheral portion of the back surface of each of the flat portion, an arcuate portion connecting the distal ends of the base portion
It is characterized by being formed.

[0007]

According to the double floor panel of the present invention, the connecting portion is provided so as to protrude from the back surface of the flat plate portion, so that no space is required between the panel bodies, and therefore the size is limited. since there can be made a high-strength connecting portions. In addition, the bending portion of the connecting portion between the flat plate portion and the base portion
For small, cracks rather difficulty occurs, in particular, the base and, because the bent portion between the flat portion and the base portion be formed as a part of the beam portion which is provided on the back surface of the flat plate portion is reinforced, bent There is almost no breakage due to the part. Further, since the structure is simple, easy to work even in the case of integral molding, and the structure of the forming <br/> form type is simple.

An embodiment of the present invention will be described below with reference to FIGS. FIGS. 1 and 2 show a double floor panel 1 respectively.
FIG. 2 is a plan view and a side view (hereinafter, referred to as “panel 1”). The panel 1 has four panel bodies 10, 30 each forming a square, which are connected by a connecting portion 40 to be integrally formed. Of these, three panel bodies 10 are formed in a mesh shape by forming a plurality of arc-shaped slits 14 on the surface thereof, so that the underfloor can be visually recognized. The other one of the panel bodies 30 has a smooth surface so that devices, partitions, and the like can be fixed with bolts or the like. Panel body 10 with slit and smooth panel body 30
Are arbitrarily selected according to the situation as described later.

Hereinafter, the panel body 10 will be described, but the panel body 30 has the same structure, and description thereof will be omitted. The panel body 10 is made of a resin such as polypropylene, and has a square plate-shaped flat plate portion 12, a beam portion 11 formed orthogonally to the back surface thereof, and a back surface at a peripheral portion and a central portion of the back surface of the flat plate portion 12, respectively. It comprises a cylindrical portion 13 extending to the side and leg members 20 attached to the cylindrical portion 13 respectively. The panel body 10 is standardized to a predetermined size. For example, one side of the flat plate portion 12 is 250 m.
The height of the leg member 20 is about 45 mm, and the thickness of the flat plate portion 12 and the beam portion 11 is about 2.5 mm. In the flat plate portion 12 of the panel body 10, a through hole 15 for inserting a rotary tool facing an engagement groove 25 described later is formed on the axis of the cylindrical portion 13.

As shown in FIG. 4, the leg member 20 has an upper portion through a cylindrical member 21 and a cylindrical portion 1 of the panel body 10.
The leg member 20 and the cylindrical portion 13 constitute a leg of the panel body 10. An elastic ring 23 is provided between the stepped portion 22 formed on the outer periphery of the leg member 20 and the cylindrical member 21 to prevent the propagation of an impact and to prevent "chatter" and "creaking".
The rubber seat 24 is attached to the lower end of the leg member 20 for the same purpose. Further, an engagement groove 25 for a rotary tool such as a driver is formed on the upper surface of the leg member 20. As a material of the leg member 20 or the cylindrical member 21, a resin such as polypropylene can be used. However, in consideration of the durability of the screw thread, for example, only the cylindrical member 21 may be formed of metal. . In this case, the cylindrical member 21 is separately formed.

The connecting portion 40 is formed integrally with the beam portion 11 at two places at the center of each side of each of the panel bodies 10 and 30. As shown in FIG. 3, the connecting portion is configured such that a part of the beam portion 11 is cut out in a rectangular shape, and upper cross sections thereof are connected to each other by an arc-shaped portion 41. That is, the connecting portion 4
0 is formed so as to have a substantially U-shaped cross section as a whole from a base portion 42 orthogonal to the flat plate portion 12 and an arc-shaped portion 41 connecting the base portion 42, but the base portion 42 retains a part of the beam portion 11 as it is. We are using. The upper and lower surfaces of the arc-shaped portion 41 form an arc so that the deformation is uniform when a bending force is applied. As a result, the central portion is thin. At one corner of the panel body, that is, at the upper surface corresponding to the four corners of the panel, a concave portion 16 into which a connecting member 52 described later is fitted is formed.

As shown in the figure, a panel as a unit is constituted by arranging four square panel bodies in a square shape, but the panel bodies 10 and 10 having an appropriate shape such as a rectangle, a triangle, and a hexagon are formed. 30 may be combined in an appropriate number and an appropriate shape.

In order to form a double floor using the panel 1 configured as described above, first, a sheet 51 for absorbing fine irregularities is laid on a floor base 50 and bonded thereto.
Are sequentially arranged. Next, in order to connect the panels, they are connected to each other by attaching a connecting member 52 to the through hole 15 as shown in FIGS. Here, as shown in FIGS. 5 and 6, the connecting member 52 has four convex portions 53 fitted in the through holes 15 at predetermined intervals, and the four panel members 10 or 30 of four adjacent panel members 10 or 30 are provided. The projections 53 can be fitted into the through holes 15, respectively.

At this time, if there are irregularities on the floor substrate 50, the legs of the panel bodies 10 and 30 can be lengthened by rotating the leg member 20 to absorb the irregularities. Even if a difference in height occurs between 10 and 30, this difference is absorbed by the flexibility of the connecting portion 40. Note that this leg member 20
Can be easily performed from the floor upper surface side by using the engagement groove 25 by a rotating tool such as a screwdriver inserted through the through hole 15 located on the floor upper surface by removing the connecting member 52 as necessary. .

When the floor finishing material 54 is laid and adhered on the upper surface of the panel 1 thus laid, the construction is completed. According to the floor structure constituted by the panel 1,
Cables and the like can be arranged in the space 55 formed below the panel 1 to perform underfloor wiring. Then, by fixing the surface of the smooth panel body 30 that is to be arranged at a predetermined interval with a screw, it is possible to arrange and fix a partition or the like at an almost arbitrary position. In addition, through the slits 14 of the panel body 10 with slits, which are uniformly arranged on the entire floor surface, it is possible to check the wiring state under the floor and the like over almost the entire area of the floor surface as before.

According to the panel of this embodiment, the connecting portion 40
Is formed from a base portion 42 orthogonal to the flat plate portion 12 and an arc-shaped portion 41 connecting the base portion to the flat plate portion 12, and does not require a space between the panel bodies 10 and 30 for forming the connecting portion 40.
Since the size of the connecting portion 40 itself is not limited, the connecting portion 40 can have a sufficient thickness and width and a high strength.
Particularly, the base portion 42 is provided on the back surface of the flat plate portion 12 and the beam portion 11 is provided.
The base 4 is easy to apply force because it is configured as a part of
2 is reinforced, and the bent portion between the flat plate portion 12 and the base portion 42 is reinforced, so that the strength is greatly improved and almost no breakage occurs. Therefore, the effect of absorbing the unevenness by the connecting portion 40 is made sufficiently strong, and the adaptability in the field is high.

Further, since the structure is simple, the steps are simple even in the case of integral molding, and the structure of the molding die is also simple, so that the manufacturing cost can be reduced. Further, according to the panel 1, there is an effect that fixing by means of a screw such as a partition is realized, and furthermore, the overall weight is reduced, and the benefit of having a slit on the surface of the panel is substantially maintained. And since the panel is unitized, the handleability of the panel and the laying workability are not impaired.

The present invention is not limited to the embodiment described above. For example, the connecting portion 40 is formed integrally with the panel members 10 and 30 in advance, but the connecting portions are welded after the panel members 10 and 30 are formed. You may. In this case, for example, up to the center of the arc-shaped portion 41 of the connecting portion 41 may be integrally formed with the respective panel bodies 10 and 30, and the ends thereof may be welded. In addition, the legs are the panel bodies 10, 30
And a structure in which the leg member 20 is simply fitted.

[0019]

As is clear from the above description, according to the double floor panel of the present invention, the connecting portion is formed by the base portion orthogonal to the flat plate portion and the arc-shaped portion connecting the base portion. space without requiring, therefore, since there are limits to the size, can be made high-strength connecting portions.
In addition, the bent portion of the connecting portion between the flat plate portion and the base portion is small.
Therefore , cracks are unlikely to occur, and in particular, when the base is formed as a part of a beam provided on the back surface of the flat plate, the strength is greatly improved and breakage hardly occurs. Therefore, there is an effect that the unevenness can be sufficiently absorbed at the connection portion and the adaptability in the field is high. In addition, since the structure is simple, the process is simple even when integrally molded .
Since the structure of the molding die is simple, there is also an effect that the manufacturing cost can be reduced.
