STRUCTURE FOR FLOOR OF DRY METHOD BUILDING

摘要

The present invention relates to a floor structure for a dry support system-based building characterized of reduced construction period and light-weight structure, so as to overcome problems associated with the traditional wet support system including the construction period and the building weights due to the self-weight of concrete.  The floor structure of the present invention comprises: a deck joined by joists, welding or bolts; a low-density insulator of 50-200 kg/m3 having multiple air layers and excellent insulation, heat insulation and sound insulation properties, the low-density insulator being inserted and filled inside the deck to prevent deformation caused by external forces; a plate or wire mesh deposited over the deck filled with the low-density insulator to prevent deformation of the floor structure caused by external forces; a high-density insulator of 300-500 kg/m3 deposited over the plate or wire mesh, the high-density insulator having excellent stability against external forces; a finish underground material formed of a cement board to be deposited over the high-density insulator; and an anchor member penetrating downwards into the low-density insulator from the finish underground material, the anchor being fixedly installed at regular intervals to prevent deformation of the floor structure caused by external forces, wherein the low-density and high-density insulators are refractory fiber-reinforced members or rock wool.
