Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel for constructing a floor of an office or the like using a large number of telephones and OA equipment, that is, a floor panel for constructing an OA floor. The present invention provides a novel panel structure in the case of constructing a double floor by arranging a large number of surfaces in a detachable manner.

[0002]

2. Description of the Related Art Conventionally, as floor panels for OA floors of this type, many means have been proposed for constructing a double floor by joining and combining isosceles triangle or square resin panels provided with legs on the back surface. (For example, Japanese Utility Model Publication No. 7-48854, Japanese Utility Model Publication No. 7-56436, Japanese Utility Model Publication No. 7-32081, Japanese Patent Application Laid-Open No. 8-184163, Utility Model Registration No. 2528443, etc.)

[0003] In addition, when the type of wiring increases, dedicated grooves for accommodating the wiring are provided as needed, and the respective wirings are bundled according to purpose and function to some extent and accommodated in the dedicated grooves. Connection to is also performed. In this case, in the groove portion for accommodating the main wiring bundle, a groove cover fitting is fitted between floor panels to keep the floor surface flush (Japanese Patent Laid-Open No. Hei 6-322949; 564
No. 36), or a method of covering the groove space with a long U-shaped metal frame (Japanese Patent Application Laid-Open No. 8-184163).

However, in order to fit the groove cover into the panel block and support it, it is necessary to separately prepare a special panel having a groove cover support mechanism, and the groove space is formed by a U-shaped metal frame. The covering method has the disadvantage that the weight is heavy.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a floor panel made of a hard resin having a square shape, the same material having a long side having a length equal to one side of the square panel and a short side having a length corresponding to a groove width. An object of the present invention is to provide a complete free access OA floor in which a wiring groove can be easily formed in an arbitrary portion by combining with a rectangular floor panel having the same height. Further, it is possible to easily change the position of the wiring groove when changing the layout, etc., and to provide a flexible floor structure when checking for a failure or changing the arrangement of the OA equipment.
