按結構(gou)形(xing)式和(he)受(shou)力特點樓梯形(xing)式可分(fen)為(wei)(wei)板式、梁(liang)式、懸挑(tiao)(剪(jian)刀(dao))式和(he)螺旋式，前兩(liang)種屬于平面受(shou)力體系，后(hou)兩(liang)種則為(wei)(wei)空(kong)間受(shou)力體系。

板(ban)(ban)式(shi)樓(lou)梯(ti)是(shi)由梯(ti)段(duan)板(ban)(ban)、平(ping)臺板(ban)(ban)和平(ping)臺梁組成。梯(ti)段(duan)板(ban)(ban)是(shi)一(yi)塊帶踏步的斜板(ban)(ban)，斜板(ban)(ban)支(zhi)承(cheng)于(yu)上、下(xia)平(ping)臺梁上，底層下(xia)端(duan)支(zhi)承(cheng)在(zai)地壟(long)墻上。板(ban)(ban)式(shi)樓(lou)梯(ti)的優點是(shi)梯(ti)段(duan)板(ban)(ban)下(xia)表面平(ping)整，支(zhi)模簡單;其缺點是(shi)梯(ti)段(duan)板(ban)(ban)跨度較大(da)時，斜板(ban)(ban)厚度較大(da)，結構材(cai)料(liao)用量較多。因(yin)此板(ban)(ban)式(shi)樓(lou)梯(ti)適用于(yu)可(ke)變荷載較小、梯(ti)段(duan)板(ban)(ban)跨度一(yi)般不大(da)于(yu)3m的情況。
