DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a double floor for laying a floor (floating floor) of a communication room, a computer room, a power room and the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, the installation of supporting legs on a concrete foundation floor of a building of this type of double floor is performed by using a fixing plate 20 using an adhesive 20 such as mortar or the like. b3 was bonded and fixed to the base floor surface D. However, since the adhesive effect of the adhesive 20 tends to decrease with the lapse of time, the fixing plate b3 of the support leg B peels off from the foundation floor surface D when subjected to an external force such as an earthquake, and the support leg Not only is the installation state of B unstable, but there is a risk of falling. The upper surface (panel mounting surface) of the panel support plate b1 of the support leg B for mounting and supporting the corner of the floor panel C.
Is formed flat, a corner portion is mounted and supported on the support plate b1, and a step is generated between the peripheral matching edges 21 of the adjacent floor panels C, thereby deteriorating the aesthetic appearance of the floor surface. Not only that, there were problems such as pedestrians tripping, problems with the installation and stability of installation devices such as computers and automation devices.

[0003] Incidentally, the cause of the step between the adjacent mating edges 21 of the floor panel C, which is mounted on the panel support plate b1 of the support leg B and laid adjacently, may be caused by the concrete foundation floor surface D of the building. Is extremely difficult to construct on a flat surface having no slope or unevenness, and the upper surface of the panel support plate b1 of each of the adjacent support legs B which are erected and arranged at intervals of the size (one side width) of the floor panel C. It is considered that the level is different depending on a slight difference in height of the base floor surface D such as the gradient and the unevenness. That is, assuming that the floor portion on which the other support leg B is erected is lower than the floor portion on which the one support leg B adjacent to the floor panel C at one side width interval is erected, The floor panel C laid in a bridging manner between the spaces B has a laying form corresponding to a height difference due to the above-mentioned gradient or unevenness which is inclined from one side toward the other support leg B side. As described above, when the laying form of the floor panel C is different, on the panel supporting plate b1 of one supporting leg B, the corner of one floor panel C adjacent to the mounting is located on the peripheral edge of the flat panel supporting plate. As a result, the mating edge 21 of the floor panel C is in a floating state, and a step is formed between the mating edge 21 of the other floor panel C and the mating edge 21.

Further, the floor panel C used for this type of double floor is generally made of a metal plate such as steel, but conventionally, the floor panel C is placed on the panel supporting plate b1 of the supporting leg B. Since the corner portion of the panel C is directly supported and supported, a contact sound (metallic sound) with the support plate b1 also formed of a metal plate is generated, and a walking vibration of a pedestrian is caused by each support leg B. Through the panel support plate b1 to the installation floor of the installation equipment, and the installation equipment may be affected by vibration.
