單(dan)(dan)(dan)跑樓梯最(zui)為(wei)簡單(dan)(dan)(dan)，適(shi)合于(yu)(yu)(yu)層高較(jiao)低(di)的(de)建筑(zhu)(zhu);雙(shuang)跑樓梯最(zui)為(wei)常(chang)見，有雙(shuang)跑直(zhi)上、雙(shuang)跑曲(qu)折(zhe)、雙(shuang)跑對(dui)折(zhe)(平行)等，適(shi)用(yong)(yong)于(yu)(yu)(yu)一般(ban)民(min)用(yong)(yong)建筑(zhu)(zhu)和工(gong)業(ye)建筑(zhu)(zhu);三(san)跑樓梯有三(san)折(zhe)式、丁字(zi)式、分合式等，多用(yong)(yong)于(yu)(yu)(yu)公共建筑(zhu)(zhu);剪刀(dao)樓梯系由(you)一對(dui)方向(xiang)相反的(de)雙(shuang)跑平行梯組(zu)成，或(huo)由(you)一對(dui)互(hu)相重(zhong)疊而又不連(lian)通(tong)的(de)單(dan)(dan)(dan)跑直(zhi)上梯構成，剖面呈交叉的(de)剪刀(dao)形(xing)(xing)，能同(tong)時通(tong)過較(jiao)多的(de)人(ren)流并(bing)節(jie)省空(kong)間(jian);螺旋轉(zhuan)梯是(shi)以扇(shan)形(xing)(xing)踏步支(zhi)承在中(zhong)立柱上，雖行走欠舒適(shi)，但(dan)節(jie)省空(kong)間(jian)，適(shi)用(yong)(yong)于(yu)(yu)(yu)人(ren)流較(jiao)少，使用(yong)(yong)不頻繁的(de)場所;圓(yuan)形(xing)(xing)、半圓(yuan)形(xing)(xing)、弧形(xing)(xing)樓梯，由(you)曲(qu)梁或(huo)曲(qu)板支(zhi)承，踏步略呈扇(shan)形(xing)(xing)，花式多樣，造(zao)型活潑，富于(yu)(yu)(yu)裝(zhuang)飾性(xing)，適(shi)用(yong)(yong)于(yu)(yu)(yu)公共建筑(zhu)(zhu)。
