金、属ダクト貫通部の防火構造。In a structure in which a metal duct passes through a hole in the wall, the gap between the duct and the wall is filled with a first fireproof material, and a fire spread preventive agent is applied to the surface of the fireproof material other than the surface that comes in contact with the duct. Furthermore, a second refractory material is provided around the duct so as to cover the contact surface between the first refractory material and the duct, and a fire spread preventive agent is applied to the exposed surface of the duct. A fireproof structure for metal and metal duct penetrations, characterized by being coated so as not to come into contact with the duct.
