按結構(gou)形式(shi)(shi)和(he)受(shou)(shou)(shou)力(li)(li)特點樓梯形式(shi)(shi)可分(fen)為板式(shi)(shi)、梁式(shi)(shi)、懸(xuan)挑(剪刀)式(shi)(shi)和(he)螺旋(xuan)式(shi)(shi)，前兩(liang)種屬于平面受(shou)(shou)(shou)力(li)(li)體系，后兩(liang)種則為空間(jian)受(shou)(shou)(shou)力(li)(li)體系。

板(ban)(ban)式樓(lou)梯(ti)是由梯(ti)段(duan)板(ban)(ban)、平臺(tai)(tai)板(ban)(ban)和(he)平臺(tai)(tai)梁(liang)組成(cheng)。梯(ti)段(duan)板(ban)(ban)是一塊帶(dai)踏步的(de)斜(xie)板(ban)(ban)，斜(xie)板(ban)(ban)支承于(yu)上、下(xia)(xia)平臺(tai)(tai)梁(liang)上，底層下(xia)(xia)端支承在地壟墻上。板(ban)(ban)式樓(lou)梯(ti)的(de)優點是梯(ti)段(duan)板(ban)(ban)下(xia)(xia)表面平整，支模簡單;其缺點是梯(ti)段(duan)板(ban)(ban)跨度(du)較(jiao)大時，斜(xie)板(ban)(ban)厚(hou)度(du)較(jiao)大，結構材料用量較(jiao)多。因此板(ban)(ban)式樓(lou)梯(ti)適(shi)用于(yu)可變(bian)荷載較(jiao)小(xiao)、梯(ti)段(duan)板(ban)(ban)跨度(du)一般(ban)不大于(yu)3m的(de)情況(kuang)。
