按結構形式和受(shou)(shou)力(li)特(te)點樓梯形式可分為(wei)板式、梁式、懸挑(剪刀)式和螺旋(xuan)式，前兩種屬(shu)于平面受(shou)(shou)力(li)體系，后兩種則為(wei)空間(jian)受(shou)(shou)力(li)體系。

板(ban)(ban)(ban)(ban)(ban)式樓(lou)梯(ti)(ti)(ti)是由(you)梯(ti)(ti)(ti)段板(ban)(ban)(ban)(ban)(ban)、平(ping)(ping)臺(tai)(tai)板(ban)(ban)(ban)(ban)(ban)和平(ping)(ping)臺(tai)(tai)梁組成。梯(ti)(ti)(ti)段板(ban)(ban)(ban)(ban)(ban)是一塊帶踏步的斜板(ban)(ban)(ban)(ban)(ban)，斜板(ban)(ban)(ban)(ban)(ban)支(zhi)(zhi)承于上(shang)、下(xia)平(ping)(ping)臺(tai)(tai)梁上(shang)，底層(ceng)下(xia)端支(zhi)(zhi)承在(zai)地壟墻上(shang)。板(ban)(ban)(ban)(ban)(ban)式樓(lou)梯(ti)(ti)(ti)的優點是梯(ti)(ti)(ti)段板(ban)(ban)(ban)(ban)(ban)下(xia)表面平(ping)(ping)整(zheng)，支(zhi)(zhi)模簡單;其缺點是梯(ti)(ti)(ti)段板(ban)(ban)(ban)(ban)(ban)跨(kua)度(du)(du)(du)較大(da)時，斜板(ban)(ban)(ban)(ban)(ban)厚度(du)(du)(du)較大(da)，結(jie)構材料用量較多。因此板(ban)(ban)(ban)(ban)(ban)式樓(lou)梯(ti)(ti)(ti)適用于可變荷(he)載較小、梯(ti)(ti)(ti)段板(ban)(ban)(ban)(ban)(ban)跨(kua)度(du)(du)(du)一般不(bu)大(da)于3m的情況。
