按結(jie)構形式(shi)和(he)受(shou)(shou)力特(te)點樓(lou)梯形式(shi)可分為板式(shi)、梁(liang)式(shi)、懸挑(剪刀)式(shi)和(he)螺(luo)旋式(shi)，前兩種(zhong)屬于平面受(shou)(shou)力體系，后兩種(zhong)則(ze)為空間受(shou)(shou)力體系。

板(ban)(ban)式樓(lou)(lou)梯(ti)是由梯(ti)段板(ban)(ban)、平臺板(ban)(ban)和(he)平臺梁組成。梯(ti)段板(ban)(ban)是一塊帶(dai)踏步的(de)斜板(ban)(ban)，斜板(ban)(ban)支(zhi)(zhi)承(cheng)于上(shang)、下(xia)平臺梁上(shang)，底(di)層(ceng)下(xia)端支(zhi)(zhi)承(cheng)在地壟墻上(shang)。板(ban)(ban)式樓(lou)(lou)梯(ti)的(de)優點(dian)是梯(ti)段板(ban)(ban)下(xia)表面(mian)平整，支(zhi)(zhi)模簡(jian)單;其缺(que)點(dian)是梯(ti)段板(ban)(ban)跨度(du)較大時，斜板(ban)(ban)厚度(du)較大，結(jie)構材(cai)料(liao)用(yong)量較多。因此板(ban)(ban)式樓(lou)(lou)梯(ti)適用(yong)于可(ke)變荷載(zai)較小、梯(ti)段板(ban)(ban)跨度(du)一般不大于3m的(de)情況。
