按結(jie)構形(xing)式(shi)和受力特點樓梯形(xing)式(shi)可分(fen)為板式(shi)、梁式(shi)、懸(xuan)挑(剪刀(dao))式(shi)和螺旋式(shi)，前兩(liang)種(zhong)(zhong)屬于平面受力體系，后兩(liang)種(zhong)(zhong)則為空間受力體系。

板(ban)(ban)式(shi)(shi)樓(lou)梯(ti)(ti)是由梯(ti)(ti)段板(ban)(ban)、平(ping)臺板(ban)(ban)和(he)平(ping)臺梁組成。梯(ti)(ti)段板(ban)(ban)是一(yi)塊帶踏步的(de)斜板(ban)(ban)，斜板(ban)(ban)支承于上、下平(ping)臺梁上，底(di)層(ceng)下端支承在(zai)地(di)壟墻上。板(ban)(ban)式(shi)(shi)樓(lou)梯(ti)(ti)的(de)優點是梯(ti)(ti)段板(ban)(ban)下表(biao)面平(ping)整，支模簡(jian)單;其缺點是梯(ti)(ti)段板(ban)(ban)跨度(du)較(jiao)(jiao)大時，斜板(ban)(ban)厚度(du)較(jiao)(jiao)大，結構材(cai)料用量較(jiao)(jiao)多。因此板(ban)(ban)式(shi)(shi)樓(lou)梯(ti)(ti)適(shi)用于可變(bian)荷載較(jiao)(jiao)小、梯(ti)(ti)段板(ban)(ban)跨度(du)一(yi)般(ban)不大于3m的(de)情(qing)況。
