Sectional type steel stair structure
The invention relates to the technical field of building stairs, in particular to a sectional type steel stair structure. The sectional type steel stair structure comprises multiple sections of steel stair units, horizontal units, first embedded parts, second embedded parts, third embedded parts, steel stair columns and steel suspenders, and each section of steel stair unit comprises two steel stair beams arranged side by side at intervals, a bottom steel sealing plate and multiple sections of steps connected to the tops of the two steel stair beams. Each step comprises a horizontal steel plate, a vertical steel plate and side sealing steel plates located at the two ends of the horizontal steel plate, the horizontal steel plate and the vertical steel plate are connected in a welded mode, the two side sealing steel plates are welded to the opposite ends of the two steel ladder beams respectively, and the tops of the vertical steel plate and the side sealing steel plates are higher than the top of the horizontal steel plate. A pouring groove is defined by the vertical steel plate, the horizontal steel plate and the two side sealing steel plates, concrete is poured in the pouring groove, and the concrete surface is flush with the tops of the vertical steel plate and the side sealing steel plates. The construction process is simple, the construction period is short, and the quality controllability is high.
本发明涉及建筑楼梯技术领域，尤其涉及一种分段式钢制楼梯结构。分段式钢制楼梯结构包括多段钢制楼梯单元、水平单元、第一预埋件、第二预埋件、第三预埋件、钢梯柱和钢吊杆，每段钢制楼梯单元均包括两个并排间隔布置的钢梯梁、底部钢封板以及连接在两个钢梯梁顶部的多节台阶，每节台阶均包括相互焊接连接的水平钢板、竖直钢板和位于水平钢板两端的侧封钢板，两块侧封钢板分别焊接在两个钢梯梁的相背的一端，竖直钢板和侧封钢板的顶部高度均高于水平钢板的顶部高度，竖直钢板、水平钢板与两块侧封钢板之间围成浇筑槽，浇筑槽内浇筑有混凝土且混凝土面与竖直钢板和侧封钢板的顶部平齐。本发明的施工工序简单、施工周期短、质量可控性高。
