【発明の効果】本発明は、以上説明したように構成され
ているので、以下に記載されるような効果を奏する。Since the present invention is configured as described above, it has the following effects.
【０００８】第１層目の防火薬液がはがれてしまって
も、第２層目で延焼を防止できる。[0008] Even if the fire retardant liquid of the first layer is peeled off, the second layer can prevent the spread of fire.
【０００９】そして、現場施工発泡ウレタンと防火薬液
の層を何層までも増やすことができる。[0009] The number of layers of urethane foam and fire-retardant liquid applied on site can be increased.
【００１０】さらに、現場施工発泡ウレタンと防火薬液
の層を何層までも増やすことにより延焼の遅延化に期待
できる。[0010] Further, by increasing the number of layers of urethane foam and fire retardant liquid applied on site, it can be expected to delay the spread of fire.
【００１１】また、現場施工発泡ウレタンと防火薬液の
層が交互に重なり合う方向は水平方向から鉛直方向まで
延焼防止効果のある方向であればどのような方向にでも
施工できる。The urethane foam and the layer of the fire-retardant liquid may be overlapped alternately in any direction from the horizontal direction to the vertical direction as long as the layer has an effect of preventing fire spread.
