按結構形式(shi)和受(shou)(shou)力(li)特(te)點樓梯形式(shi)可分(fen)為板式(shi)、梁式(shi)、懸挑(剪刀)式(shi)和螺(luo)旋(xuan)式(shi)，前兩種屬于平(ping)面受(shou)(shou)力(li)體系，后兩種則為空間受(shou)(shou)力(li)體系。

板(ban)(ban)(ban)式樓(lou)(lou)梯(ti)是由梯(ti)段板(ban)(ban)(ban)、平臺板(ban)(ban)(ban)和平臺梁組(zu)成。梯(ti)段板(ban)(ban)(ban)是一塊帶(dai)踏步的(de)斜(xie)板(ban)(ban)(ban)，斜(xie)板(ban)(ban)(ban)支承(cheng)于上、下(xia)平臺梁上，底層下(xia)端支承(cheng)在地壟墻(qiang)上。板(ban)(ban)(ban)式樓(lou)(lou)梯(ti)的(de)優點是梯(ti)段板(ban)(ban)(ban)下(xia)表面平整，支模簡單;其缺點是梯(ti)段板(ban)(ban)(ban)跨(kua)度較(jiao)大時，斜(xie)板(ban)(ban)(ban)厚度較(jiao)大，結構材(cai)料(liao)用量(liang)較(jiao)多。因此板(ban)(ban)(ban)式樓(lou)(lou)梯(ti)適用于可變荷載較(jiao)小(xiao)、梯(ti)段板(ban)(ban)(ban)跨(kua)度一般不大于3m的(de)情況。
