Abstract
A bamboo floor plate for sound insulation. A bamboo plate is made by forming flat a round bamboo cane. A wide groove is formed on the bamboo plate, and on both sides of a wide groove, narrow grooves are formed. The inside of the wide groove is insulated, and an electrode is embedded thereon to make a heating plate. The narrow grooves on the sides are arranged parallel to each other so that the cross section of the bamboo plate looks like a comb. A foam plastic sheet is placed on the surface on which the grooves are provided to form hollows. To connect the bamboo floor plate to another bamboo floor plate, a pin is inserted between the electrodes of the bamboo floor plates.
