樓(lou)梯形(xing)式

樓梯(ti)(ti)按梯(ti)(ti)段可(ke)分(fen)為單(dan)跑(pao)樓梯(ti)(ti)、雙跑(pao)樓梯(ti)(ti)和多跑(pao)樓梯(ti)(ti)。梯(ti)(ti)段的(de)平面形狀(zhuang)有直(zhi)線(xian)的(de)、折線(xian)的(de)和曲線(xian)的(de)。

單(dan)(dan)跑樓梯(ti)(ti)最為(wei)簡單(dan)(dan)，適合于層(ceng)高較(jiao)低的建(jian)(jian)筑;雙(shuang)跑樓梯(ti)(ti)最為(wei)常見，有雙(shuang)跑直(zhi)上(shang)、雙(shuang)跑曲(qu)折、雙(shuang)跑對折(平(ping)(ping)行)等，適用(yong)(yong)于一(yi)般民用(yong)(yong)建(jian)(jian)筑和(he)工(gong)業建(jian)(jian)筑;三(san)跑樓梯(ti)(ti)有三(san)折式、丁字(zi)式、分(fen)合式等，多用(yong)(yong)于公(gong)共建(jian)(jian)筑;剪刀樓梯(ti)(ti)系由一(yi)對方向相反(fan)的雙(shuang)跑平(ping)(ping)行梯(ti)(ti)組(zu)成，或由一(yi)對互相重(zhong)疊而又不連通(tong)的單(dan)(dan)跑直(zhi)上(shang)梯(ti)(ti)構(gou)成，剖面呈(cheng)交叉(cha)的剪刀形(xing)(xing)(xing)，能同時(shi)通(tong)過較(jiao)多的人流并節省空間;螺旋轉梯(ti)(ti)是以扇形(xing)(xing)(xing)踏步(bu)支承在中立(li)柱上(shang)，雖行走欠舒適，但(dan)節省空間，適用(yong)(yong)于人流較(jiao)少，使用(yong)(yong)不頻(pin)繁的場所;圓(yuan)形(xing)(xing)(xing)、半圓(yuan)形(xing)(xing)(xing)、弧形(xing)(xing)(xing)樓梯(ti)(ti)，由曲(qu)梁或曲(qu)板支承，踏步(bu)略呈(cheng)扇形(xing)(xing)(xing)，花(hua)式多樣，造型活潑，富于裝飾性，適用(yong)(yong)于公(gong)共建(jian)(jian)筑。
