【従来の技術】
特開平6−146518の明細書の従来の技術の記載欄に鋼製階段に関する問題点が記載されている。
要約すると、鋼製階段は、耐火性を有すると共に、比較的軽量にて高い構造強度が得られ、かつ施工性に優れることから広く用いられている。特にマンション、ビル等の非常階段を兼ね耐食性を求められる屋外階段等では、鋼製ささら桁に縞鋼板からなる踏板(段板)を溶接接合して一体の階段構造体に組立後、どぶ漬け亜鉛めっきを施して耐食性を高める鋼製階段が採用されている。どぶ漬け亜鉛めっき”による一体型の鋼製階段は、単層の縞鋼板を踏板に用いている。
従って、鋼製階段の欠点は騒音である。昇降に際して発生する高いレベルの騒音を防止するために、鋼製ささら桁に粘弾性樹脂層を中間に介在させた制振鋼板を溶接接合して一体の階段構造体に組立て、これを“どぶ漬け亜鉛めっき”するものは目的を達成できないので、特開平6−146518では、鋼製のささら桁に単層鋼板からなる踏板を溶接接合して一体に組立てると共に、全面に溶融亜鉛めっきが施された階段本体の各踏板の踏面部の裏面に制振鋼板を接着してなる鋼製階段を提案している。
【0003】
