Conventionally, as a floating floor of this type, the lid has only a function as a lid for opening and closing the through hole. [0003] The floating floor is formed by arranging floor panels side by side with a space above the floor of the structure, and aims to provide sound insulation and vibration isolation to the lower floor. In addition, the space between the floating floor and the floor can be used as a wiring space for arranging wiring of, for example, electric / communication cables. Therefore, when the wiring is to be set up on the floating floor after the floor panel is installed, the floor panel is partially removed, and the wiring is installed in the wiring space (or, if the wiring is already installed, the corresponding wiring is installed). After selecting), the floor panel is placed on a receiving member so that the wiring passes through the through-hole of the floor panel, and is attached, so that the wiring can be started up without performing a large-scale construction. Can be raised. However, when the floor panel is removed and attached, a jig for operating the fastener is required.
According to the above-mentioned conventional floating floor, when operating the fastening tool, an operation jig is separately prepared and the operation is performed by the jig, but it is necessary to urgently remove the floor panel. (For example, underfloor wiring inspection)
There is a problem that the work cannot be started until the jig can be procured.Depending on the structure of the fastener, a special jig may be used, and it takes time to procure the special jig. There is a problem that the floor panel cannot be easily attached or detached. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problem and to provide a floating floor on which a floor panel can be easily attached and detached without separately procuring a jig for attaching and detaching the floor panel. [0005] In order to achieve this object, a floating floor according to the present invention is characterized in that the floor panel is fixed to a lid of a through hole for vertical communication provided in the floor panel for forming a floating floor. There is provided an operation section capable of freely performing a tightening operation or a releasing operation of the tightening tool for performing the operation.

It becomes possible. On the other hand, when the lid is not used as a jig, it is merely installed on the floor panel as a lid, without securing extra jig storage space.
The floating floor space can be used effectively, and at the same time, the jig can be prevented from being lost. In addition, even when a fastener having a special structure that cannot be operated by a general-purpose jig such as a screwdriver or a spanner is employed, the operating portion of the lid is configured to be capable of operating the special fastener. The floor panel can be attached and detached without any change just by placing it. In addition, since the lid is installed on the corresponding floor panel, the work can be carried out speedily only by placing the lid near the fastener. Also, when attaching and detaching multiple floor panels, it is possible to operate each fastener at once using the lids installed on each floor panel, so a large amount of jigs must be procured separately. The floor panel can be efficiently attached / detached without doing so, and workability can be improved without extra cost. Therefore, according to the floating floor of the present invention, the lid of the floor panel through hole can be used without separately procuring a jig for detaching the floor panel regardless of the structure of the fastener. The floor panel can be easily and quickly attached and detached, and the lid can be stored in a state where it is not lost without specially securing a jig storage space. That is, it is possible to configure the floating floor in a state that is easy to assemble and maintain.
