EAVES BACK CEILING MATERIAL AND EAVES BACK CEILING STRUCTURE
PROBLEM TO BE SOLVED: To improve fire resistance by preventing high-temperature gas from being transmitted through an eaves back ceiling material 21 to make an entry into an eaves back space 5, even when a surface of an eaves soffit is exposed to a flame of a fire and the like, while improving cost reduction and workability.SOLUTION: An eaves back ceiling material 21 includes: a plurality of base materials 22 and 22 made of an inorganic material such as a volcanic glass multi-layer board; metal foil 23 that is arranged between the base materials 22 and 22; and an incombustible coating film 26 which is provided on a surface of the base material 22, positioned on the opposite side of an eaves back space 5 during execution of work, of the plurality of base materials 22 and 22, and which has a gas shielding effect. The incombustible coating film 26 comprises a resin, and a layered clay mineral with swelling properties, which swells in water in association with the state of being turned into a coating material.SELECTED DRAWING: Figure 3
【課題】低コスト化及び施工性の向上を図りつつ、火災等の炎に軒天井の表面が曝されても高温ガスが軒裏天井材２１を透過して軒裏空間５に進入しないようにして耐火性を向上させる。【解決手段】軒裏天井材２１は、火山性ガラス質複層板等の無機材料からなる複数枚の基材２２，２２と、これら基材２２，２２の間に配設された金属箔２３と、複数枚の基材２２，２２のうち施工時に軒裏空間５と反対側に位置する基材２２の表面に設けられ、気体遮蔽効果を有する不燃性塗膜２６とを備えている。不燃性塗膜２６は、塗料化に伴って水中で膨潤する膨潤性を有する層状粘土鉱物と樹脂とを備えてなる。【選択図】図３
