按結構(gou)形(xing)式和受(shou)力(li)(li)特點(dian)樓梯形(xing)式可分為板式、梁式、懸挑(tiao)(剪(jian)刀)式和螺旋(xuan)式，前兩(liang)種(zhong)屬于平面受(shou)力(li)(li)體系(xi)，后兩(liang)種(zhong)則為空間受(shou)力(li)(li)體系(xi)。

板(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)是(shi)(shi)由(you)梯(ti)(ti)段板(ban)(ban)(ban)、平(ping)臺(tai)板(ban)(ban)(ban)和平(ping)臺(tai)梁組成。梯(ti)(ti)段板(ban)(ban)(ban)是(shi)(shi)一(yi)塊帶踏步的(de)(de)斜板(ban)(ban)(ban)，斜板(ban)(ban)(ban)支承(cheng)于(yu)上(shang)、下平(ping)臺(tai)梁上(shang)，底(di)層下端支承(cheng)在地壟墻上(shang)。板(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)的(de)(de)優點(dian)是(shi)(shi)梯(ti)(ti)段板(ban)(ban)(ban)下表面平(ping)整，支模簡單;其(qi)缺點(dian)是(shi)(shi)梯(ti)(ti)段板(ban)(ban)(ban)跨(kua)度(du)較(jiao)大(da)時，斜板(ban)(ban)(ban)厚度(du)較(jiao)大(da)，結構材料用(yong)量較(jiao)多。因此板(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)適用(yong)于(yu)可(ke)變(bian)荷載較(jiao)小(xiao)、梯(ti)(ti)段板(ban)(ban)(ban)跨(kua)度(du)一(yi)般不大(da)于(yu)3m的(de)(de)情(qing)況(kuang)。
