STEEL STAIR DRY-TYPE LANDING STRUCTURE
To achieve walking stability of a landing plate by increasing the strength of the landing plate and reducing vibrations with a simple structure.SOLUTION: A landing of a stair 1 is formed by stacking a lower landing plate 11 on the lower surface of a landing upper plate 10. Both ends of the lower landing plate 11 are fixed to the inner surface 7a of a side plate 7. The lower landing plate is divided into a plurality of support steel plates 15, and a connection gap 25 is formed between the divided support steel plates 15. The support steel plates 15 connect connection perpendicular pieces 20, 21 downward from one edge 17 and the other edge 18 of a horizontal body plate 16. A horizontal connection closing piece 23 is connected to the lower end of the connection perpendicular piece 21. The connection closing piece 23 is positioned in the connection gap 25 in a horizontal view. An anti-shaking piece 27 is inserted between the connection perpendicular pieces 20, 21.SELECTED DRAWING: Figure 1
【課題】踊り場板の強度を高め、単純な構造で、振動を軽減して踊り場板の歩行安定を図る。【解決手段】階段１の踊り場であって、踊り場上板１０の下面に下踊り場板１１を積層してなる。下踊り場板１１の両端を側板７の内面７ａに固定した。下踊り場板を、複数の支持鋼鈑１５に分割して、分割した各支持鋼鈑１５の間に連結間隙２５を形成した。支持鋼鈑１５は水平の本体板１６の一縁１７、他縁１８から下方に向けて連結垂直片２０、２１を連設する。連結垂直片２１の下端に水平方向の連結塞ぎ片２３を連設し、連結塞ぎ片２３は水平視で連結間隙２５に位置する。連結垂直片２０、２１の間に防振片２７を挿入する。【選択図】図１
