單跑樓梯(ti)(ti)(ti)最(zui)為簡單，適(shi)合于(yu)層高較(jiao)低的建(jian)(jian)(jian)筑(zhu);雙(shuang)跑樓梯(ti)(ti)(ti)最(zui)為常見，有(you)雙(shuang)跑直上(shang)、雙(shuang)跑曲(qu)折(zhe)、雙(shuang)跑對(dui)折(zhe)(平行)等，適(shi)用(yong)(yong)于(yu)一般民用(yong)(yong)建(jian)(jian)(jian)筑(zhu)和工業建(jian)(jian)(jian)筑(zhu);三(san)(san)跑樓梯(ti)(ti)(ti)有(you)三(san)(san)折(zhe)式、丁字式、分合式等，多(duo)(duo)用(yong)(yong)于(yu)公(gong)共建(jian)(jian)(jian)筑(zhu);剪刀(dao)樓梯(ti)(ti)(ti)系(xi)由一對(dui)方向相(xiang)反(fan)的雙(shuang)跑平行梯(ti)(ti)(ti)組成，或由一對(dui)互相(xiang)重(zhong)疊而(er)又不連通的單跑直上(shang)梯(ti)(ti)(ti)構成，剖(pou)面呈交叉的剪刀(dao)形(xing)(xing)，能同時通過較(jiao)多(duo)(duo)的人(ren)流并節(jie)省空間;螺(luo)旋轉(zhuan)梯(ti)(ti)(ti)是以扇形(xing)(xing)踏步支(zhi)承(cheng)在中立柱上(shang)，雖(sui)行走欠舒適(shi)，但節(jie)省空間，適(shi)用(yong)(yong)于(yu)人(ren)流較(jiao)少，使(shi)用(yong)(yong)不頻繁(fan)的場所;圓形(xing)(xing)、半圓形(xing)(xing)、弧形(xing)(xing)樓梯(ti)(ti)(ti)，由曲(qu)梁或曲(qu)板支(zhi)承(cheng)，踏步略呈扇形(xing)(xing)，花式多(duo)(duo)樣(yang)，造型活潑(po)，富于(yu)裝飾性，適(shi)用(yong)(yong)于(yu)公(gong)共建(jian)(jian)(jian)筑(zhu)。
