按結構形式(shi)(shi)(shi)和受(shou)力特(te)點(dian)樓梯形式(shi)(shi)(shi)可分為板式(shi)(shi)(shi)、梁(liang)式(shi)(shi)(shi)、懸(xuan)挑(剪刀(dao))式(shi)(shi)(shi)和螺(luo)旋式(shi)(shi)(shi)，前兩種(zhong)屬于平面受(shou)力體系(xi)，后兩種(zhong)則(ze)為空間受(shou)力體系(xi)。

板(ban)(ban)(ban)式樓(lou)梯(ti)(ti)是(shi)由梯(ti)(ti)段(duan)板(ban)(ban)(ban)、平(ping)(ping)臺板(ban)(ban)(ban)和平(ping)(ping)臺梁組成。梯(ti)(ti)段(duan)板(ban)(ban)(ban)是(shi)一(yi)塊帶踏步的(de)斜板(ban)(ban)(ban)，斜板(ban)(ban)(ban)支(zhi)(zhi)承(cheng)于上、下平(ping)(ping)臺梁上，底層下端(duan)支(zhi)(zhi)承(cheng)在地壟墻上。板(ban)(ban)(ban)式樓(lou)梯(ti)(ti)的(de)優點(dian)是(shi)梯(ti)(ti)段(duan)板(ban)(ban)(ban)下表面平(ping)(ping)整，支(zhi)(zhi)模(mo)簡(jian)單;其缺點(dian)是(shi)梯(ti)(ti)段(duan)板(ban)(ban)(ban)跨(kua)度較(jiao)大時，斜板(ban)(ban)(ban)厚度較(jiao)大，結構材(cai)料用量較(jiao)多(duo)。因此板(ban)(ban)(ban)式樓(lou)梯(ti)(ti)適(shi)用于可變荷載(zai)較(jiao)小(xiao)、梯(ti)(ti)段(duan)板(ban)(ban)(ban)跨(kua)度一(yi)般(ban)不大于3m的(de)情況。
