單跑(pao)(pao)樓(lou)(lou)梯(ti)(ti)(ti)(ti)最為簡單，適(shi)合(he)于(yu)層高較(jiao)(jiao)低的建(jian)筑;雙(shuang)跑(pao)(pao)樓(lou)(lou)梯(ti)(ti)(ti)(ti)最為常(chang)見，有(you)雙(shuang)跑(pao)(pao)直(zhi)上(shang)、雙(shuang)跑(pao)(pao)曲折、雙(shuang)跑(pao)(pao)對折(平行)等，適(shi)用(yong)于(yu)一(yi)般民用(yong)建(jian)筑和工業(ye)建(jian)筑;三(san)跑(pao)(pao)樓(lou)(lou)梯(ti)(ti)(ti)(ti)有(you)三(san)折式(shi)(shi)(shi)、丁(ding)字式(shi)(shi)(shi)、分合(he)式(shi)(shi)(shi)等，多(duo)用(yong)于(yu)公共建(jian)筑;剪(jian)刀(dao)樓(lou)(lou)梯(ti)(ti)(ti)(ti)系由(you)(you)一(yi)對方向相反(fan)的雙(shuang)跑(pao)(pao)平行梯(ti)(ti)(ti)(ti)組成，或由(you)(you)一(yi)對互相重疊而又(you)不連通的單跑(pao)(pao)直(zhi)上(shang)梯(ti)(ti)(ti)(ti)構成，剖(pou)面呈交叉的剪(jian)刀(dao)形(xing)(xing)(xing)，能同時通過(guo)較(jiao)(jiao)多(duo)的人流(liu)并節省空(kong)(kong)間(jian);螺(luo)旋轉梯(ti)(ti)(ti)(ti)是以扇形(xing)(xing)(xing)踏步(bu)支承在中立柱上(shang)，雖行走欠舒適(shi)，但(dan)節省空(kong)(kong)間(jian)，適(shi)用(yong)于(yu)人流(liu)較(jiao)(jiao)少(shao)，使用(yong)不頻繁的場(chang)所(suo);圓(yuan)(yuan)形(xing)(xing)(xing)、半(ban)圓(yuan)(yuan)形(xing)(xing)(xing)、弧形(xing)(xing)(xing)樓(lou)(lou)梯(ti)(ti)(ti)(ti)，由(you)(you)曲梁或曲板支承，踏步(bu)略呈扇形(xing)(xing)(xing)，花式(shi)(shi)(shi)多(duo)樣，造型活(huo)潑，富于(yu)裝飾性，適(shi)用(yong)于(yu)公共建(jian)筑。
