EARTHQUAKE-PROOF SLIT CORE MATERIAL AND EARTHQUAKE-PROOF SLIT

摘要

PROBLEM TO BE SOLVED: To provide an earthquake-proof slit core material for an earthquake-proof slit having excellent fitting strength between rib members and the earthquake-proof slit material, and also having excellent deformation restoration properties and fireproof performance.SOLUTION: There is provided an earthquake-proof core material for an earthquake-proof slit interposed between a structural column and a non-structural wall of a building, the earthquake-proof slit core material including a synthetic resin foamed board with a restorable deformation of 75% or more and a fireproof material provided on at least one surface side of end surfaces along the longitudinal direction of the synthetic resin foamed board. In the earthquake-proof core material, the fireproof material is formed of metallic foil and has a U-shaped cross-section, and the end surface side of the synthetic resin foamed board is covered with the U-shaped metallic foil.SELECTED DRAWING: Figure 1
