樓梯形式(shi)

樓梯(ti)(ti)按梯(ti)(ti)段(duan)可分為單跑樓梯(ti)(ti)、雙跑樓梯(ti)(ti)和多跑樓梯(ti)(ti)。梯(ti)(ti)段(duan)的平面形狀有直線(xian)的、折線(xian)的和曲線(xian)的。

單跑樓(lou)梯(ti)(ti)最為簡單，適(shi)合于(yu)層高較低的(de)建(jian)(jian)筑;雙(shuang)跑樓(lou)梯(ti)(ti)最為常見(jian)，有(you)雙(shuang)跑直上(shang)(shang)、雙(shuang)跑曲(qu)折、雙(shuang)跑對(dui)折(平行)等(deng)，適(shi)用(yong)于(yu)一(yi)般民用(yong)建(jian)(jian)筑和工(gong)業建(jian)(jian)筑;三跑樓(lou)梯(ti)(ti)有(you)三折式、丁字式、分合式等(deng)，多(duo)(duo)用(yong)于(yu)公(gong)共(gong)建(jian)(jian)筑;剪刀樓(lou)梯(ti)(ti)系(xi)由一(yi)對(dui)方向相反(fan)的(de)雙(shuang)跑平行梯(ti)(ti)組成，或(huo)由一(yi)對(dui)互相重疊(die)而(er)又不(bu)連(lian)通的(de)單跑直上(shang)(shang)梯(ti)(ti)構成，剖面呈交叉的(de)剪刀形(xing)，能同(tong)時通過較多(duo)(duo)的(de)人(ren)流并節省空(kong)(kong)間(jian);螺旋轉(zhuan)梯(ti)(ti)是以扇(shan)形(xing)踏步(bu)支(zhi)承(cheng)在中(zhong)立柱上(shang)(shang)，雖行走(zou)欠舒適(shi)，但節省空(kong)(kong)間(jian)，適(shi)用(yong)于(yu)人(ren)流較少，使用(yong)不(bu)頻繁的(de)場(chang)所;圓(yuan)(yuan)形(xing)、半(ban)圓(yuan)(yuan)形(xing)、弧形(xing)樓(lou)梯(ti)(ti)，由曲(qu)梁(liang)或(huo)曲(qu)板(ban)支(zhi)承(cheng)，踏步(bu)略呈扇(shan)形(xing)，花式多(duo)(duo)樣(yang)，造(zao)型(xing)活(huo)潑，富于(yu)裝飾(shi)性，適(shi)用(yong)于(yu)公(gong)共(gong)建(jian)(jian)筑。
