按結構形式(shi)(shi)和(he)(he)受力(li)特(te)點樓梯形式(shi)(shi)可分為(wei)板式(shi)(shi)、梁式(shi)(shi)、懸挑(tiao)(剪刀)式(shi)(shi)和(he)(he)螺旋(xuan)式(shi)(shi)，前兩種(zhong)屬(shu)于(yu)平面受力(li)體系，后兩種(zhong)則為(wei)空(kong)間(jian)受力(li)體系。

板(ban)(ban)(ban)式(shi)(shi)樓(lou)梯(ti)是由梯(ti)段(duan)板(ban)(ban)(ban)、平臺板(ban)(ban)(ban)和平臺梁(liang)組成。梯(ti)段(duan)板(ban)(ban)(ban)是一塊帶踏步的(de)斜(xie)板(ban)(ban)(ban)，斜(xie)板(ban)(ban)(ban)支承(cheng)于(yu)上(shang)、下平臺梁(liang)上(shang)，底層(ceng)下端支承(cheng)在地壟墻上(shang)。板(ban)(ban)(ban)式(shi)(shi)樓(lou)梯(ti)的(de)優點是梯(ti)段(duan)板(ban)(ban)(ban)下表面平整，支模簡(jian)單;其缺(que)點是梯(ti)段(duan)板(ban)(ban)(ban)跨(kua)度(du)較大時，斜(xie)板(ban)(ban)(ban)厚(hou)度(du)較大，結構材料用(yong)量較多。因此板(ban)(ban)(ban)式(shi)(shi)樓(lou)梯(ti)適用(yong)于(yu)可(ke)變荷載較小、梯(ti)段(duan)板(ban)(ban)(ban)跨(kua)度(du)一般不(bu)大于(yu)3m的(de)情(qing)況。
