樓(lou)(lou)梯按(an)梯段可分為單(dan)跑樓(lou)(lou)梯、雙跑樓(lou)(lou)梯和多跑樓(lou)(lou)梯。梯段的平面形狀(zhuang)有直線(xian)(xian)的、折線(xian)(xian)的和曲線(xian)(xian)的。

單跑(pao)樓(lou)梯(ti)(ti)最為簡(jian)單，適合(he)(he)于層(ceng)高較(jiao)低的(de)(de)建(jian)(jian)(jian)筑(zhu)(zhu)(zhu);雙(shuang)跑(pao)樓(lou)梯(ti)(ti)最為常見，有雙(shuang)跑(pao)直上、雙(shuang)跑(pao)曲(qu)折(zhe)、雙(shuang)跑(pao)對(dui)折(zhe)(平行(xing)(xing))等，適用(yong)(yong)于一般民用(yong)(yong)建(jian)(jian)(jian)筑(zhu)(zhu)(zhu)和工業(ye)建(jian)(jian)(jian)筑(zhu)(zhu)(zhu);三跑(pao)樓(lou)梯(ti)(ti)有三折(zhe)式(shi)、丁(ding)字(zi)式(shi)、分合(he)(he)式(shi)等，多用(yong)(yong)于公共建(jian)(jian)(jian)筑(zhu)(zhu)(zhu);剪刀樓(lou)梯(ti)(ti)系由一對(dui)方(fang)向相(xiang)反的(de)(de)雙(shuang)跑(pao)平行(xing)(xing)梯(ti)(ti)組(zu)成，或(huo)(huo)由一對(dui)互(hu)相(xiang)重(zhong)疊而(er)又(you)不連通的(de)(de)單跑(pao)直上梯(ti)(ti)構成，剖面呈(cheng)交叉的(de)(de)剪刀形(xing)，能同時通過較(jiao)多的(de)(de)人(ren)(ren)流并(bing)節省空(kong)間;螺旋轉梯(ti)(ti)是(shi)以扇形(xing)踏步支(zhi)承在中立柱(zhu)上，雖行(xing)(xing)走欠舒(shu)適，但節省空(kong)間，適用(yong)(yong)于人(ren)(ren)流較(jiao)少，使用(yong)(yong)不頻繁的(de)(de)場所(suo);圓形(xing)、半圓形(xing)、弧形(xing)樓(lou)梯(ti)(ti)，由曲(qu)梁或(huo)(huo)曲(qu)板支(zhi)承，踏步略(lve)呈(cheng)扇形(xing)，花式(shi)多樣(yang)，造型活(huo)潑，富于裝飾性，適用(yong)(yong)于公共建(jian)(jian)(jian)筑(zhu)(zhu)(zhu)。
