FLAT DECK AND FIRE RETARDANT PARTITION STRUCTURE
To provide a flat deck and a fire retardant partition structure excellent in fire retardant property through suppression of shrinkage of filler inside of ribs upon fire.SOLUTION: A flat deck is provided with a flat part 11, ribs 12 (121,122) projected on one surface 11D of the flat part 11, and a filler 13 arranged inside of the ribs 12, wherein a ratio of a density at a boundary surface part of the ribs of the filler 13 to a density at a core part of the filler 13 is 1.01 or more and 1.20 or less.SELECTED DRAWING: Figure 1
【課題】火災時におけるリブ内部の充填物の収縮を抑制し、防火性に優れるフラットデッキ及び防火区画構造を提供する【解決手段】フラット部１１と、フラット部１１の一方の面１１Ｄに突設されるリブ１２（１２１，１２２）と、リブ１２の内部に設けられた充填物１３とを備え、充填物１３のコア部位の密度に対する充填物１３のリブ界面部位の密度の比が１．０１以上１．２０以下である、フラットデッキ。【選択図】図１
