COMPOSITE FLOOR OF DECK PLATE AND GRC PANEL, AND DTY METHOD COMPOSITE ROOF

摘要

PURPOSE:To obtain excellent sound insulating efficiency by fixing GRC panels to the surface of a deck plate through a sound insulating member and rubber sheet, and providing a rubber sheet layer to the surface of a flat plate bringing into contact with the bottom of the deck plate. CONSTITUTION:Heat insulating/sound insulating plates 5 are laminated to the inside of GRC panels 3 having ribs 4 bent at right angles with a pair of opposed edges, and a rubber sheet 7 is laid under the bottom of the sound insulating plates 5 to fix to the surface of a steel deck 1. After that, spaces between the ribs 4 of adjacent GRC panels 3 are filled with sealing compound 8. Then, a shielding plate 12 and rubber sheet 13 adhere between the bottom of the steel deck 1 and the surface of a floor joist 2. According to the constitution, a floor having excellent sound insulating efficiency can be obtained.
