Double floor system

The present invention relates to a double bottom system, and more particularly, to a double bottom system having a double floor panel manufactured by processing a thermosetting resin.

In general, a floor of a residential building or an office building is formed by mortar being poured on a concrete slab to form a base surface, and a floor material such as tiles is laid on the base surface. On the floor thus formed, various office equipment and advanced equipment such as electricity, electronics, and computer equipment are placed in the space. At this time, if the wires for supplying power to these equipment is installed to be exposed to the outside, the interior of the building is not neat and dirty. In addition, there is a problem that the possibility of a safety accident due to the unprotected neglect of the wire and communication line is high. Therefore, in recent years, a double-floor system is provided to form a double floor on the floor of an office building to accommodate devices such as wiring and air conditioning facilities in the space between the panel and the base surface. As a result, the interior aesthetics of the building can be neat and safety accidents can be prevented.
