按結構形式和(he)受(shou)力(li)特點樓梯形式可分(fen)為板式、梁式、懸挑(剪(jian)刀)式和(he)螺旋式，前兩種(zhong)屬(shu)于平面(mian)受(shou)力(li)體(ti)系，后兩種(zhong)則為空間受(shou)力(li)體(ti)系。

板(ban)(ban)(ban)式(shi)(shi)樓(lou)梯(ti)(ti)是(shi)由梯(ti)(ti)段板(ban)(ban)(ban)、平(ping)臺板(ban)(ban)(ban)和平(ping)臺梁組成(cheng)。梯(ti)(ti)段板(ban)(ban)(ban)是(shi)一塊帶踏步的(de)斜(xie)板(ban)(ban)(ban)，斜(xie)板(ban)(ban)(ban)支承于上、下(xia)平(ping)臺梁上，底層下(xia)端支承在地壟墻上。板(ban)(ban)(ban)式(shi)(shi)樓(lou)梯(ti)(ti)的(de)優點是(shi)梯(ti)(ti)段板(ban)(ban)(ban)下(xia)表面(mian)平(ping)整，支模簡(jian)單;其缺點是(shi)梯(ti)(ti)段板(ban)(ban)(ban)跨度較(jiao)(jiao)大時，斜(xie)板(ban)(ban)(ban)厚度較(jiao)(jiao)大，結(jie)構(gou)材料(liao)用(yong)量較(jiao)(jiao)多(duo)。因此板(ban)(ban)(ban)式(shi)(shi)樓(lou)梯(ti)(ti)適用(yong)于可變荷載較(jiao)(jiao)小、梯(ti)(ti)段板(ban)(ban)(ban)跨度一般(ban)不(bu)大于3m的(de)情況。
