Title:
FIRE-RESISTING STRUCTURE OF PENETRATION PART
Document Type and Number:
Japanese Patent JP2016128718
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fire-resisting structure of a penetration part, which can prevent a thermal expansion fire-resisting device from coming off a fireproof partition body even when wiring and a piping material are subjected to force for moving them in the axial direction and can prevent a through hole from becoming a path of smoke.SOLUTION: A fire-resisting structure of a penetration part provided in a fireproof partition wall W of a building is constructed such that a wire conduit P is inserted in a through hole Wa and a thermal expansion fire-resisting device 11 is provided between the inner peripheral surface of the through hole Wa and the outer peripheral surface of the wire conduit P. In this fire-resisting structure of the penetration part, the thermal expansion fire-resisting device 11 is arranged to surround the outer peripheral surface of the wire conduit P with a gap Ka left therefrom and is fixed to the fireproof partition wall W. In the gap Ka, a filling material 21 is provided for closing the gap Ka while permitting movement of the wire conduit P in the axial direction relative to the thermal expansion fire-resisting device 11.SELECTED DRAWING: Figure 6
