樓梯按(an)梯段(duan)(duan)可(ke)分為單跑樓梯、雙跑樓梯和多跑樓梯。梯段(duan)(duan)的平面(mian)形狀有直(zhi)線(xian)的、折線(xian)的和曲線(xian)的。

單(dan)(dan)跑(pao)樓(lou)(lou)梯(ti)(ti)最為簡單(dan)(dan)，適(shi)合(he)于(yu)層高較(jiao)低的(de)(de)(de)建(jian)(jian)筑;雙跑(pao)樓(lou)(lou)梯(ti)(ti)最為常見，有雙跑(pao)直(zhi)上(shang)、雙跑(pao)曲折(zhe)、雙跑(pao)對(dui)折(zhe)(平行(xing))等，適(shi)用(yong)(yong)于(yu)一(yi)般(ban)民用(yong)(yong)建(jian)(jian)筑和工(gong)業(ye)建(jian)(jian)筑;三跑(pao)樓(lou)(lou)梯(ti)(ti)有三折(zhe)式(shi)、丁字(zi)式(shi)、分合(he)式(shi)等，多(duo)用(yong)(yong)于(yu)公(gong)共建(jian)(jian)筑;剪刀(dao)樓(lou)(lou)梯(ti)(ti)系由(you)一(yi)對(dui)方向相反的(de)(de)(de)雙跑(pao)平行(xing)梯(ti)(ti)組成(cheng)，或(huo)由(you)一(yi)對(dui)互(hu)相重疊而又不(bu)連(lian)通的(de)(de)(de)單(dan)(dan)跑(pao)直(zhi)上(shang)梯(ti)(ti)構成(cheng)，剖面呈交叉的(de)(de)(de)剪刀(dao)形(xing)，能同時通過(guo)較(jiao)多(duo)的(de)(de)(de)人(ren)流并節省(sheng)空(kong)間(jian);螺旋轉梯(ti)(ti)是以扇(shan)形(xing)踏步(bu)支承在中(zhong)立(li)柱(zhu)上(shang)，雖行(xing)走欠舒適(shi)，但節省(sheng)空(kong)間(jian)，適(shi)用(yong)(yong)于(yu)人(ren)流較(jiao)少(shao)，使用(yong)(yong)不(bu)頻繁的(de)(de)(de)場所(suo);圓形(xing)、半(ban)圓形(xing)、弧(hu)形(xing)樓(lou)(lou)梯(ti)(ti)，由(you)曲梁或(huo)曲板支承，踏步(bu)略呈扇(shan)形(xing)，花式(shi)多(duo)樣，造型活潑(po)，富于(yu)裝飾(shi)性，適(shi)用(yong)(yong)于(yu)公(gong)共建(jian)(jian)筑。
