Title:
CLOSING MEMBER AND CLOSING STRUCTURE OF OPEN HOLE
Document Type and Number:
Japanese Patent JP2023086749
Kind Code:
A
Abstract:
To provide a closing member capable of suppressing formation of a clearance extending linearly in a direction of penetrating a fire compartment wall in a case where a block part is compressively deformed in a thickness direction, and a closing structure of an open hole.SOLUTION: In a closing member 30, a plurality of compressively deformable block parts 34 are aligned in a longitudinal direction X, and all the block parts 34 are connected at one end side in a thickness direction Z of each block part 34. The closing member 30 is housed in a gap in an open hole in a state where a penetration direction and a depth direction Y of the open hole in a fire compartment wall coincide with each other. The closing member 30 has a slit 32 extending in the thickness direction Z and the depth direction Y between the side surfaces of the block parts 34 adjacent to each other in the longitudinal direction X. The side surfaces of the block part 34 that partitions the slit 32 intersect with a virtual surface M extending in the depth direction Y and the thickness direction Z.SELECTED DRAWING: Figure 2
