STAIRWAY DAMPING COLUMN AND STAIRWAY DAMPING STRUCTURE
PROBLEM TO BE SOLVED: To provide a stairway damping metal fitting capable of suppressing pitching of a stairway which occurs when climbing up and down a stairway.SOLUTION: A stairway damping column 30 comprises: a column 31 disposed below a force beam 11 supporting a foot board 12 of a stairway 10 and fixing a lower end portion 31a to the floor; and a vibration absorption member 32 provided on an upper end portion 31b of the column 31. The vibration absorption member 32 has a such configuration that a girder support surface (first piece 32a) fixed to a lower flange 11c, which is the bottom surface of the force beam 11, is arranged to enlarge in the direction of extension S of the force beam 11 more than the cross sectional area of the column 31.SELECTED DRAWING: Figure 3
【課題】階段昇降時に生じる階段の縦揺れを抑制することができる階段制振金具を提供すること。【解決手段】階段制振支柱３０は、階段１０の踏み板１２を支持する力桁１１の下方に配置させて、下端部３１ａを床に固定させる柱部３１と、柱部３１の上端部３１ｂに設けられた防振部３２と、を備えている。そして、この防振部３２は、力桁１１の底面である下側フランジ１１ｃに固定される桁支持面（第１片３２ａ）が柱部３１の断面積よりも力桁１１の延伸方向Ｓに沿って拡大されている構成となっている。【選択図】図３
