按結(jie)構形(xing)式(shi)(shi)和受(shou)力(li)特(te)點樓梯(ti)形(xing)式(shi)(shi)可分為板式(shi)(shi)、梁式(shi)(shi)、懸(xuan)挑(剪(jian)刀)式(shi)(shi)和螺旋式(shi)(shi)，前兩(liang)種屬于平面受(shou)力(li)體系(xi)，后兩(liang)種則(ze)為空間受(shou)力(li)體系(xi)。

板(ban)(ban)(ban)(ban)(ban)式樓(lou)梯(ti)(ti)(ti)(ti)是由梯(ti)(ti)(ti)(ti)段板(ban)(ban)(ban)(ban)(ban)、平(ping)臺板(ban)(ban)(ban)(ban)(ban)和平(ping)臺梁組成(cheng)。梯(ti)(ti)(ti)(ti)段板(ban)(ban)(ban)(ban)(ban)是一(yi)塊帶踏(ta)步的斜板(ban)(ban)(ban)(ban)(ban)，斜板(ban)(ban)(ban)(ban)(ban)支承于上(shang)(shang)、下(xia)平(ping)臺梁上(shang)(shang)，底層下(xia)端支承在地壟墻上(shang)(shang)。板(ban)(ban)(ban)(ban)(ban)式樓(lou)梯(ti)(ti)(ti)(ti)的優點(dian)是梯(ti)(ti)(ti)(ti)段板(ban)(ban)(ban)(ban)(ban)下(xia)表面(mian)平(ping)整，支模簡單;其缺點(dian)是梯(ti)(ti)(ti)(ti)段板(ban)(ban)(ban)(ban)(ban)跨度較(jiao)大(da)時(shi)，斜板(ban)(ban)(ban)(ban)(ban)厚度較(jiao)大(da)，結構(gou)材料用量(liang)較(jiao)多。因(yin)此板(ban)(ban)(ban)(ban)(ban)式樓(lou)梯(ti)(ti)(ti)(ti)適用于可(ke)變荷載(zai)較(jiao)小、梯(ti)(ti)(ti)(ti)段板(ban)(ban)(ban)(ban)(ban)跨度一(yi)般不(bu)大(da)于3m的情況(kuang)。
