按結(jie)構形(xing)式(shi)和(he)(he)受(shou)力特點樓(lou)梯(ti)形(xing)式(shi)可(ke)分(fen)為(wei)板式(shi)、梁式(shi)、懸挑(剪刀)式(shi)和(he)(he)螺旋式(shi)，前兩種屬于平面受(shou)力體系，后兩種則(ze)為(wei)空(kong)間(jian)受(shou)力體系。

板(ban)(ban)(ban)式(shi)樓梯(ti)(ti)(ti)是(shi)(shi)由梯(ti)(ti)(ti)段(duan)板(ban)(ban)(ban)、平臺(tai)板(ban)(ban)(ban)和平臺(tai)梁組(zu)成。梯(ti)(ti)(ti)段(duan)板(ban)(ban)(ban)是(shi)(shi)一塊帶踏步的斜(xie)板(ban)(ban)(ban)，斜(xie)板(ban)(ban)(ban)支承于上、下(xia)平臺(tai)梁上，底層下(xia)端支承在(zai)地壟墻上。板(ban)(ban)(ban)式(shi)樓梯(ti)(ti)(ti)的優點(dian)是(shi)(shi)梯(ti)(ti)(ti)段(duan)板(ban)(ban)(ban)下(xia)表面平整(zheng)，支模簡單(dan);其(qi)缺點(dian)是(shi)(shi)梯(ti)(ti)(ti)段(duan)板(ban)(ban)(ban)跨(kua)度(du)較大(da)(da)(da)時，斜(xie)板(ban)(ban)(ban)厚(hou)度(du)較大(da)(da)(da)，結構材(cai)料用(yong)量較多(duo)。因此板(ban)(ban)(ban)式(shi)樓梯(ti)(ti)(ti)適(shi)用(yong)于可(ke)變荷載較小、梯(ti)(ti)(ti)段(duan)板(ban)(ban)(ban)跨(kua)度(du)一般不大(da)(da)(da)于3m的情況(kuang)。
