樓梯形(xing)式

樓(lou)梯(ti)(ti)(ti)按梯(ti)(ti)(ti)段可分為單(dan)跑(pao)樓(lou)梯(ti)(ti)(ti)、雙跑(pao)樓(lou)梯(ti)(ti)(ti)和(he)多跑(pao)樓(lou)梯(ti)(ti)(ti)。梯(ti)(ti)(ti)段的(de)平面(mian)形狀有直(zhi)線(xian)的(de)、折線(xian)的(de)和(he)曲線(xian)的(de)。

單跑樓(lou)梯(ti)(ti)(ti)最為簡單，適合(he)于(yu)層高(gao)較(jiao)(jiao)低(di)的建(jian)筑;雙跑樓(lou)梯(ti)(ti)(ti)最為常見，有雙跑直(zhi)上、雙跑曲(qu)折、雙跑對(dui)(dui)折(平行)等，適用(yong)(yong)(yong)于(yu)一(yi)般民(min)用(yong)(yong)(yong)建(jian)筑和工(gong)業建(jian)筑;三(san)跑樓(lou)梯(ti)(ti)(ti)有三(san)折式(shi)、丁(ding)字式(shi)、分合(he)式(shi)等，多(duo)用(yong)(yong)(yong)于(yu)公(gong)共建(jian)筑;剪刀樓(lou)梯(ti)(ti)(ti)系由(you)一(yi)對(dui)(dui)方向(xiang)相(xiang)反的雙跑平行梯(ti)(ti)(ti)組成(cheng)，或由(you)一(yi)對(dui)(dui)互相(xiang)重疊(die)而(er)又不(bu)連通的單跑直(zhi)上梯(ti)(ti)(ti)構成(cheng)，剖(pou)面呈交叉的剪刀形(xing)(xing)，能同時(shi)通過較(jiao)(jiao)多(duo)的人(ren)流并(bing)節省空(kong)間;螺(luo)旋轉梯(ti)(ti)(ti)是以扇(shan)形(xing)(xing)踏(ta)步(bu)支承在中立(li)柱上，雖行走欠(qian)舒適，但(dan)節省空(kong)間，適用(yong)(yong)(yong)于(yu)人(ren)流較(jiao)(jiao)少，使(shi)用(yong)(yong)(yong)不(bu)頻繁的場所(suo);圓(yuan)形(xing)(xing)、半圓(yuan)形(xing)(xing)、弧形(xing)(xing)樓(lou)梯(ti)(ti)(ti)，由(you)曲(qu)梁或曲(qu)板支承，踏(ta)步(bu)略(lve)呈扇(shan)形(xing)(xing)，花式(shi)多(duo)樣，造型活潑(po)，富(fu)于(yu)裝飾性，適用(yong)(yong)(yong)于(yu)公(gong)共建(jian)筑。
