Description

  The present invention relates to a floor panel for a free access floor, and more particularly to a floor panel for a free access floor in which a surface finish plate is integrally provided on the upper surface of a panel body formed into a fixed rectangular shape by aluminum die casting (casting method). is there.

  In this type of floor panel for free access floors, resin tiles such as vinyl chloride resin and metal plates such as stainless steel are used as the surface finish plate provided on the upper surface of the panel body. After the surface finish plate 2 is overlaid and integrated on the upper surface of the panel body 1 as shown in FIG. 3, the peripheral portion B of the panel body 1 and the surface finish plate 2 is cut with a cutter ( (Alternatively, grinding, file, etc.) are cut (or ground) together with C to finish to a predetermined size.

On the other hand, since the JIS standard is not established for this kind of floor panel for the free access floor, the size (standard) differs somewhat depending on the manufacturer.
Therefore, for example, when the surface finish plate is cracked or chipped, or when it is necessary to replace the surface finish plate when changing the pattern in the room, the peripheral edge of the panel body and the surface finish plate is equivalent to cutting and grinding together with a cutter etc. Therefore, it is difficult to replace the surface finish plate with a certain size. After forming the surface finish plate slightly larger and superimposing it on the upper surface of the panel body, the peripheral edge of the surface finish plate can be integrated with a special canna or file. Thus, grinding finishing was performed. For this reason, it takes a long time and cost to replace the surface finish plate, and eventually the surface finish plate is given up and the entire floor panel is replaced.
However, if the entire floor panel is replaced, the floor panel laying pitch may shift even if it is from the same manufacturer, and may not fit on the existing support legs.

  Note that the above prior art known to the applicant of the present application is not related to a known literature, and therefore, prior art document information is not disclosed in the present specification.

  The present invention has been made in view of such a situation, and only the panel body needs to be finished to a predetermined size when final sizing as a floor panel is performed at the time of manufacture, and the surface finish plate is replaced. The floor panel for a free access floor can be replaced relatively easily and inexpensively without changing the external dimensions of the panel body before and after the refinishing of the surface finish plate. Is intended to provide.

  A floor panel for a free access floor according to the present invention that achieves such an object is a floor panel for a free access floor in which a surface finish plate is integrally provided on the upper surface of a panel body formed in a regular rectangular shape by aluminum die casting. The four-sided rib having the same height as the thickness of the surface finish plate is protruded and formed on the entire upper surface periphery of the panel body, and is formed in the same shape and the same size as the inside of the concave portion surrounded by the four-sided rib. It is characterized in that a surface finish plate is integrally installed.

According to the floor panel for a free access floor according to the present invention, a quadrilateral rib having the same height as the thickness of the surface finish plate is formed to project over the entire upper surface periphery of the panel main body, and the recess is surrounded by the quadrilateral rib. Since the surface finish plate formed in the same shape and size as the inside of the recess is integrally stored and installed, the surface finish plate has no influence on the size (finished outer dimension) determination as a floor panel. .
Therefore, when the final size processing as a floor panel is performed at the time of manufacture, it is only necessary to finish the panel body to a predetermined dimension. Since it only needs to be formed in the same shape and size as the inside of the recess, the external dimensions of the panel main body are not changed before and after the replacement of the surface finish plate.
Therefore, compared with the conventional floor panel, the refinishing of the surface finish plate can be performed comprehensively easily and inexpensively.

  In addition, when the final size processing as a floor panel is performed at the time of production, it is only necessary to finish the panel body to a predetermined dimension, and the panel body and the surface finish plate are not cut (or ground) together. The only cutting waste generated during sizing is the aluminum material coming out of the panel body, and unlike conventional products, there is no mixing of different metal materials other than resin materials and aluminum materials. The surface finish plate is not limited to the resin material, and it is easy to apply a metal plate material such as a stainless steel harder than the panel body.

  Hereinafter, specific preferred embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the illustrated embodiments, and various variations are conceivable.

  A floor panel for a free access floor according to the present invention is formed by integrally superposing a surface finish plate 2 on an upper surface of a panel main body 1 formed into a fixed rectangular shape by die casting using an aluminum alloy.

  The panel body 1 is formed in a predetermined rectangular shape (for example, a square having a side of 60 cm), and has the same height as the thickness (H1) of the surface finish plate 2 on the entire periphery of the upper surface thereof. A quadrilateral rib 11 is formed to protrude.

  The four circumferential ribs 11 are formed in the same body at the same time as the panel body 1 is die-cast, and are surface-finished over the entire outer periphery of the panel body 1 to an appropriate width (H2) from the outer peripheral end surface 12 of the panel body 1 to the inside. 2 projecting to the same height as the thickness (H1). At this time, the four-round rib 11 may be formed with the same width (H2) over the entire circumference, or may be formed with a width of any one side or two sides different from the width of the other sides.

  And in the upper surface of the panel main body 1, more specifically, in the concave 13 formed by being surrounded by the four-sided ribs 11, the surface finish plate 2 previously formed in the same shape and size as the concave 13 is accommodated without any gap. The panel body 1 and the panel main body 1 are superposed and installed.

  As the surface finish plate 2, a resin tile such as vinyl chloride resin or a metal plate such as stainless steel having an appropriate thickness (for example, about 1 to 3 mm) is used as in the past. It is formed in the same shape and size as the inside of the recess 13 formed by the rib 11, and is stored and installed in the recess 13 of the panel body 1 without a gap.

By the way, as a means for integrally storing and installing the surface finish plate 2 in the recess 13, as in the conventional case, adhesive fixing using an adhesive or double-sided adhesive tape, or mechanical fixing using screws or stud bolts. Etc. can be adopted.
In addition, when using metal plates, such as a stainless steel material, as the surface finishing board 2, it is also possible to use what gave the appropriate pattern, coating, or plating to the surface of a metal plate.

Thus, when manufacturing the main floor panel, the panel body 1 is formed into a regular rectangular shape having a predetermined size by aluminum die casting, and the same height as the thickness (H1) of the surface finish plate 2 is formed on the upper surface side. The four-round rib 11 having the protrusion is formed to protrude. On the other hand, the surface finishing plate 2 is formed in advance and in the same shape and size as the inside of the concave recess 13 formed by the four-round rib 11.
Then, before or after the surface finishing plate 2 is housed and integrated in the recess 13 of the panel body 1, the four rounds of the panel body 1 are ground and subjected to final size processing as a floor panel. Finish to the specified dimensions.
