PROBLEM TO BE SOLVED: To provide a high-reliability structure of a fire compartment penetration part, which can reduce the occurrence of defects such as a partial collapse of the structure of the fire compartment penetration part.SOLUTION: A structure of a fire compartment penetration part includes a through-hole that is formed in a compartment of a building, a bus duct that is inserted through the through-hole, and an incombustible material for almost closing a gap between te through-hole and an outer periphery of a long body. An outer peripheral part, which is inserted through the through-hole, of the long body is covered with a slide member. A gap between the slide member and the incombustible material is closed with a heat-resistant seal material. The long body and the heat-resistant seal material can be moved in the longitudinal direction of the long body via the slide member. |
