樓梯按梯段(duan)可分(fen)為(wei)單跑(pao)樓梯、雙跑(pao)樓梯和(he)多跑(pao)樓梯。梯段(duan)的平面形狀有直(zhi)線(xian)的、折線(xian)的和(he)曲線(xian)的。

單(dan)跑(pao)(pao)樓梯(ti)最為簡(jian)單(dan)，適合于(yu)(yu)層高較低的建(jian)(jian)(jian)筑;雙(shuang)跑(pao)(pao)樓梯(ti)最為常見，有雙(shuang)跑(pao)(pao)直上、雙(shuang)跑(pao)(pao)曲折、雙(shuang)跑(pao)(pao)對(dui)折(平行(xing))等，適用(yong)于(yu)(yu)一般民用(yong)建(jian)(jian)(jian)筑和工業建(jian)(jian)(jian)筑;三跑(pao)(pao)樓梯(ti)有三折式(shi)、丁字式(shi)、分合式(shi)等，多(duo)用(yong)于(yu)(yu)公共(gong)建(jian)(jian)(jian)筑;剪刀樓梯(ti)系由(you)一對(dui)方向相(xiang)反的雙(shuang)跑(pao)(pao)平行(xing)梯(ti)組成(cheng)，或由(you)一對(dui)互相(xiang)重疊而又不連通(tong)的單(dan)跑(pao)(pao)直上梯(ti)構成(cheng)，剖面呈交叉的剪刀形，能同時通(tong)過較多(duo)的人流并節省空(kong)間;螺(luo)旋轉梯(ti)是以扇(shan)形踏步支(zhi)承在中立柱上，雖行(xing)走欠(qian)舒適，但節省空(kong)間，適用(yong)于(yu)(yu)人流較少，使用(yong)不頻(pin)繁的場所;圓形、半圓形、弧形樓梯(ti)，由(you)曲梁或曲板支(zhi)承，踏步略呈扇(shan)形，花式(shi)多(duo)樣(yang)，造型活潑，富于(yu)(yu)裝飾(shi)性，適用(yong)于(yu)(yu)公共(gong)建(jian)(jian)(jian)筑。
