單(dan)(dan)跑(pao)樓(lou)梯(ti)(ti)(ti)(ti)最為簡(jian)單(dan)(dan)，適合(he)于層高較(jiao)低(di)的(de)建(jian)(jian)筑(zhu)(zhu);雙(shuang)(shuang)跑(pao)樓(lou)梯(ti)(ti)(ti)(ti)最為常見，有(you)雙(shuang)(shuang)跑(pao)直上(shang)、雙(shuang)(shuang)跑(pao)曲(qu)(qu)折(zhe)、雙(shuang)(shuang)跑(pao)對(dui)(dui)(dui)折(zhe)(平行(xing)(xing))等，適用(yong)于一般(ban)民用(yong)建(jian)(jian)筑(zhu)(zhu)和(he)工業建(jian)(jian)筑(zhu)(zhu);三跑(pao)樓(lou)梯(ti)(ti)(ti)(ti)有(you)三折(zhe)式、丁字式、分合(he)式等，多(duo)用(yong)于公共(gong)建(jian)(jian)筑(zhu)(zhu);剪刀樓(lou)梯(ti)(ti)(ti)(ti)系由一對(dui)(dui)(dui)方(fang)向(xiang)相反的(de)雙(shuang)(shuang)跑(pao)平行(xing)(xing)梯(ti)(ti)(ti)(ti)組成(cheng)，或(huo)由一對(dui)(dui)(dui)互相重疊(die)而又不連通的(de)單(dan)(dan)跑(pao)直上(shang)梯(ti)(ti)(ti)(ti)構成(cheng)，剖面(mian)呈交叉的(de)剪刀形(xing)(xing)，能(neng)同時通過較(jiao)多(duo)的(de)人(ren)流并節省空間;螺旋轉(zhuan)梯(ti)(ti)(ti)(ti)是以扇形(xing)(xing)踏步支承在中立(li)柱上(shang)，雖行(xing)(xing)走欠(qian)舒適，但(dan)節省空間，適用(yong)于人(ren)流較(jiao)少，使(shi)用(yong)不頻繁的(de)場(chang)所;圓(yuan)形(xing)(xing)、半圓(yuan)形(xing)(xing)、弧形(xing)(xing)樓(lou)梯(ti)(ti)(ti)(ti)，由曲(qu)(qu)梁(liang)或(huo)曲(qu)(qu)板支承，踏步略呈扇形(xing)(xing)，花(hua)式多(duo)樣，造型活(huo)潑，富于裝(zhuang)飾性，適用(yong)于公共(gong)建(jian)(jian)筑(zhu)(zhu)。
