JPH0711235Y2 - Support for floor panels in double floors - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a double floor in which a floor panel is laid above a floor base made of concrete or the like with an appropriate gap.
The present invention relates to an improved support for the floor panel.

[Conventional technology]

In this type of double floor, as a support for a floor panel, in Japanese Utility Model Publication No. 61-76045 as a prior art, a plurality of support projections for the floor panel are appropriately spaced on the upper surface of a rectangular bottom plate. It is disclosed that a seat portion that abuts on the floor base is projected downward with a small size at the position of the support projection on the lower surface of the bottom plate while projecting upward.

[Problems to be solved by the device]

According to this prior art, a gap is formed between the upper surface of the bottom plate of the support and the lower surface of the floor panel with the same vertical gap size as the protruding size of the support protrusions. Can be freely crawled, and moreover, the support is only in contact with the floor base at the seat portion provided at the support protrusion portion, and the bottom plate extends horizontally so that Since it can be bent and deformed, even if there is unevenness on the upper surface of the floor base, there is an advantage that the unevenness of the floor substrate can be reliably dealt with by the flexural deformation of the bottom plate.

However, on the other hand, as in this prior art, in the configuration in which the support projection and the seat portion are provided on the upper and lower surfaces of the bottom plate in a protruding manner, the means for manufacturing this is to integrally mold them with a synthetic resin or by aluminum die casting. It must be integrally molded, or the support projection and seat formed separately from metal or synthetic resin, etc., must be fixed to the bottom plate made of a thin metal plate by adhesion or screwing, etc. However, since the shape is complicated, there is a problem that the manufacturing cost increases.

The present invention, without impairing the wiring function of the cords, and
It is an object of the present invention to apply a support, which is capable of accurately dealing with unevenness of a floor substrate, in a form that can be manufactured at extremely low cost.

[Means for Solving the Problems]

In order to achieve this purpose, the present invention uses a plate material such as metal,
Forming a cylindrical frame body with a square shape in plan view that is placed on the floor base and having an upper and lower opening, and at each side plate of the frame body, at an appropriate portion except for the vicinity of the connecting portion of the adjacent side plates, upward or downward. A cord insertion groove that is opened at the side is formed by cutting into a depth that allows the side plate to bend and deform in the vertical direction at the cord insertion groove position, and the upper edge of each side plate is supported on a floor panel laid above the floor base. It is configured to be formed in the part.

[Function and effect of device]

According to this structure, since the cord insertion grooves are formed in the side plates of the supporting body by opening, the insides of the supporting bodies adjacent to each other can be communicated with each other, so that the cords can be freely wired under the floor panel. Moreover, since each side plate can be bent and deformed in the vertical direction at the location of the cord insertion groove, even if the floor base has irregularities, each side plate can be bent and deformed to follow the irregularities of the floor base. Therefore, it is possible to prevent the support from rising or loosening.

In other words, the cord insertion groove serves not only as a groove for passing the cords but also as a function of deforming the support column in accordance with the unevenness of the floor base.

Further, since the support body is rectangular in plan view, the connecting portion of the adjacent side plates, that is, the corner portion of the support body has a bent shape in plan view, so the thickness of the support body should be increased. In addition, the supporting strength for the floor panel can be improved, and the material cost can be saved accordingly. The material cost can be saved, and the support has a cord insertion groove in a simple rectangular frame body. Combined with the fact that it is a simple shape that only forms a notch, and that it can be easily processed,
The manufacturing cost can be significantly reduced.

Therefore, according to the present invention, the manufacturing cost can be remarkably reduced, while the support is capable of supporting the floor panel in a stable state by accurately responding to the unevenness of the floor base without impairing the wiring function of the cords. Has the effect that can.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings (FIGS. 1 and 2). In the drawings, reference numeral 1 is a floor having a rectangular shape in plan view which is laid above a floor base A with appropriate gaps. Panels, reference numerals 2, respectively, show supports for the floor panel 1, and the floor panel 1 has a structure in which a core material 4 such as lightweight concrete or a honeycomb material is filled inside a box body 3 having an upward opening. The four hooks of the box body 3 are bent downward to form the locking hook pieces 5 over the entire length.

The support 2 is formed of a thin metal plate in a cylindrical frame body that is open vertically and is rectangular in plan view.
In 2a, cord insertion grooves 6 having upward openings with respect to cords B such as a power source are formed by cutting out at portions other than the vicinity of the connecting portions 2b of adjacent side plates 2a, and the portions of the cord insertion grooves 6 are removed. An engaging hook piece 5 of the floor panel 1 is provided on the upper edge of the side plate 2a.
To be fitted.

At this time, the depth dimension of the cord insertion groove 6, in other words, the height dimension of the side plate 2a at the bottom surface portion of the cord insertion groove 6, is determined by the height of each side plate 2a at the bottom surface portion of the cord insertion groove 6.
Set so that it can be bent and deformed vertically with a light force.

A rug 7 such as a carpet is laid on the upper surface of each floor panel 1.

According to this structure, since the cord insertion grooves 6 are cut into the side plates 2a of the support body 2 so that the interiors of the adjacent support bodies 2 communicate with each other, the wiring cords B can be freely placed under each floor panel 1. Can be crawled to each side plate 2a
However, since it can be bent and deformed in the vertical direction at the position of the cord insertion groove 6, even if the floor substrate A has irregularities, the lower surface of each side plate 2a can be closely adhered to the floor substrate A by following the irregularities and supporting. The body 2 can be installed in a loose state.

And, the connecting portion 2b of the side plates 2a adjacent to each other in the support 2
By bending in a plan view, the strength against a downward load increases, so that the support strength for the floor panel 1 can be improved without increasing the thickness of the support body 2.
It is possible to save the material cost, and because of this, the supporting body 2 has a simple shape in which the cord insertion groove 6 is formed by slitting it in a mere rectangular tube-shaped frame body, and its machining can be performed very easily. Combined with what can be done, the manufacturing cost can be reduced.

The cord insertion groove 6 may be formed at a plurality of positions on each side plate 2a, as shown by the chain double-dashed line in FIG.
As shown in FIGS. 3 and 4, it may be opened so as to open downward. (However, as shown in FIGS. 1 and 2, the cord B can be inserted into and removed from the cord insertion groove 6 from above with the support 2 installed on the floor base A, so that the wiring work can be performed easily. When the locking hook pieces 5 of the floor panel 1 are fitted on the side plates 2a of the support 2 as in the above embodiment, the positions of the floor panel 1 and the support 2 are automatically determined. The laying work of the floor panel 1 can be performed quickly, and the floor panel 1 can be prevented from shifting after being laid.

When the cord insertion groove 6 is opened upward, the side plates 2a of the cord insertion groove 6 at the adjacent support bodies 2 are located.
Alternatively, as shown by the alternate long and short dash line in FIG. 2, a downward U-shaped connecting body 8 may be fitted to connect the adjacent support bodies 2 to each other.

Needless to say, the support 2 may be a triangle in plan view as shown in FIG. 5 or a hexagon in plan view.
