FIREPROOF SHIELD MATERIAL AND FIREPROOF SHIELD STRUCTURE
PROBLEM TO BE SOLVED: To enable a structure that is thinner than a thicker structure in which multiple thick gypsum boards are stacked to achieve the same or higher level of heat shield property and fire resistance as the thicker structure.SOLUTION: A fireproof shield material 1 is formed of front and rear layers 1a, 1b, which are formed by laminating in a thickness direction and compacting two layers among a thermal expanding layer in which a thermal expansion material such as expanded graphite or vermiculite that expands on heating is blended into a wool mat in which hot-melt heat-resistant inorganic fibers made of rock wool or glass wool pile up and intertwine, a flame arresting layer in which a thermal fusion material such as glass that prevents the flame from penetrating by melting on heating is blended into the wool mat, and a heat absorbing layer into which a heat absorbing material such as aluminium hydroxide that absorbs heat is blended. A fireproof shield structure is formed of the fireproof shield material 1 and a plate-like body formed of gypsum boards 5, 5 that are integrally laminated at least on one of front and rear faces of the fireproof shield material 1.SELECTED DRAWING: Figure 1
【課題】厚さの大きい複数枚の石膏ボードを重ねた構造と同等以上の遮熱性、耐火性がそれよりも薄い厚さの構造によって達成できるようにする。【解決手段】耐火シールド材１は、ロックウール又はガラスウールからなる熱溶融性耐熱無機繊維が積み重なって絡み合ったウールマットに、加熱により膨張する膨張黒鉛やバーミキュライト等の加熱膨張材が配合された加熱膨張層と、同様のウールマットに、加熱により溶融して火炎の透過を防止するガラス等の加熱溶融材が配合された火炎防止層と、同様のウールマットに、熱を吸収する水酸化アルミニウム等の熱吸収材が配合された熱吸収層とのうちの２つの層が厚さ方向に積層されて圧密化された表裏層１ａ，１ｂからなるものとする。この耐火シールド材１と、耐火シールド材１の表裏面の少なくとも一方に一体的に積層された石膏ボード５，５からなる板状体とを設けて耐火シールド構造とする。【選択図】図１
