To provide a structure for the penetrating part of a vessel fire compartment, where the sides of pipes receive less thermal influence, which is easy in constructing, and which exhibits excellent fireproof performance, even if steel plates and the like are used for the compartment.
The structure for the penetrating part of a vessel fire compartment has: pipes 5 which penetrate the penetration hole of a compartment arranged at a division in a vessel; an edge material side plate 3 arranged at the penetration hole so as to extends toward outside from the penetration hole; an incombustible blocking board 4 arranged inside the edge material side plate and covers the penetration hole; a holding member 6 which holds the incombustible blocking board inside the edge material side plate; a thermally expansive fire resistant sheet 7 which covers the penetration hole and the pipes; and a sealing material which covers the space between the pipes and the thermally expansive fire resistant sheet. The pipes penetrate the penetration hole arranged at the incombustible blocking board, and the thermally expansive fire resistant sheet is fixed to the periphery of the edge material side plate and the pipes.
