按結構形(xing)(xing)式(shi)(shi)和受(shou)力特(te)點樓梯形(xing)(xing)式(shi)(shi)可(ke)分為板式(shi)(shi)、梁式(shi)(shi)、懸挑(tiao)(剪刀)式(shi)(shi)和螺旋式(shi)(shi)，前兩種屬于(yu)平面受(shou)力體系，后兩種則為空間(jian)受(shou)力體系。

板(ban)(ban)(ban)(ban)式(shi)樓(lou)(lou)梯(ti)(ti)是(shi)由梯(ti)(ti)段板(ban)(ban)(ban)(ban)、平(ping)臺板(ban)(ban)(ban)(ban)和平(ping)臺梁組成(cheng)。梯(ti)(ti)段板(ban)(ban)(ban)(ban)是(shi)一塊帶踏步(bu)的斜(xie)板(ban)(ban)(ban)(ban)，斜(xie)板(ban)(ban)(ban)(ban)支(zhi)承于上(shang)、下平(ping)臺梁上(shang)，底層(ceng)下端支(zhi)承在(zai)地壟(long)墻上(shang)。板(ban)(ban)(ban)(ban)式(shi)樓(lou)(lou)梯(ti)(ti)的優點(dian)是(shi)梯(ti)(ti)段板(ban)(ban)(ban)(ban)下表面平(ping)整，支(zhi)模簡單;其缺點(dian)是(shi)梯(ti)(ti)段板(ban)(ban)(ban)(ban)跨(kua)(kua)度(du)(du)較大時，斜(xie)板(ban)(ban)(ban)(ban)厚度(du)(du)較大，結構材料用(yong)(yong)量較多。因此板(ban)(ban)(ban)(ban)式(shi)樓(lou)(lou)梯(ti)(ti)適用(yong)(yong)于可變荷載較小、梯(ti)(ti)段板(ban)(ban)(ban)(ban)跨(kua)(kua)度(du)(du)一般不大于3m的情況(kuang)。
