Description

  The present invention relates to an access floor panel. More specifically, the through holes are provided in the upper and lower panels of the panel so as to be spaced from each other at a predetermined interval, so that noise caused by a resonance phenomenon is not generated. Since the upper, middle and lower plates are combined to form a panel, it is light in weight and easy to install, as well as an access floor panel that can be reused to reduce environmental pollution. It is about.

  In general, offices such as intelligent buildings equipped with office automation facilities increase the wiring efficiency of electric wires and communication lines used for various electric / electronic devices, and consider the indoor air permeability and aesthetics. An access floor panel having a double floor is widely used, and the office environment such as simplification of the room and prevention of static electricity can be improved by burying the wiring in the floor.

  The access floor panel is usually formed to have a certain length, and is fixed to support members spaced from each other at a certain interval on the bottom surface, and is used by being connected to each other. This is a cement mortar and PB (Particle Board). ) A plywood is formed by filling a metal panel, and a plywood is divided into a metal panel on which metal plates are stacked so that a hollow portion is formed in a constant thickness.

  Here, the PB plywood is a product produced by mixing a crushed wood (chip) with an adhesive by hot pressing, and is also called a chip board.

  The metal panel filled with the cement mortar has a problem that it is not only difficult to transport and install because it is filled with cement mortar, but also causes excessive safety and induces a safety accident. .

  The metal panel filled with the PB plywood is lighter in weight than the metal panel filled with cement mortar. However, the pulverized wood is mixed with an adhesive to produce a product by hot pressure. In the case of being dried by being expanded by moisture, there is a problem that it is easily damaged by external impact before being expanded by moisture.

  In order to sequentially install the metal panel filled with the cement mortar and PB plywood at the bottom, the metal panel must be cut and installed in a space smaller than the metal panel. There was a problem that dust was generated from mortar and PB plywood and the surroundings were contaminated.

  In addition, when trying to dispose of the metal panel filled with the cement mortar and PB plywood, it is difficult to separate the cement mortar and PB plywood from the metal panel, which makes it difficult to recycle. If the metal panel is discarded in a state where it is in a wet state, there is a problem of polluting the environment.

  In addition, the metal panel formed by stacking metal plate materials so that a hollow portion is formed inside is light and empty inside, so it is easier to install than a metal panel filled with cement mortar and PB plywood. Of course, since cement mortar and PB plywood are not filled into the metal panel, environmental pollution due to the filling filled in the metal panel can be eliminated, but in the hollow portion sealed by the impact transmitted when the pedestrian walks There was a problem that sound reverberation and vibration due to resonance phenomenon occurred greatly, and stuttering due to resonance phenomenon occurred.
