按結構形(xing)式和受(shou)力特(te)點樓梯形(xing)式可分為(wei)板式、梁式、懸挑(剪刀)式和螺旋式，前兩種屬于平(ping)面受(shou)力體系，后兩種則為(wei)空(kong)間受(shou)力體系。

板(ban)(ban)(ban)(ban)式樓(lou)梯(ti)(ti)是(shi)由梯(ti)(ti)段(duan)(duan)(duan)板(ban)(ban)(ban)(ban)、平臺(tai)板(ban)(ban)(ban)(ban)和平臺(tai)梁(liang)組(zu)成。梯(ti)(ti)段(duan)(duan)(duan)板(ban)(ban)(ban)(ban)是(shi)一塊帶踏步的斜板(ban)(ban)(ban)(ban)，斜板(ban)(ban)(ban)(ban)支承于(yu)(yu)上、下(xia)平臺(tai)梁(liang)上，底(di)層(ceng)下(xia)端(duan)支承在地壟(long)墻上。板(ban)(ban)(ban)(ban)式樓(lou)梯(ti)(ti)的優(you)點是(shi)梯(ti)(ti)段(duan)(duan)(duan)板(ban)(ban)(ban)(ban)下(xia)表面平整，支模簡單;其缺(que)點是(shi)梯(ti)(ti)段(duan)(duan)(duan)板(ban)(ban)(ban)(ban)跨度較大(da)(da)時，斜板(ban)(ban)(ban)(ban)厚度較大(da)(da)，結構材料用(yong)量(liang)較多。因此板(ban)(ban)(ban)(ban)式樓(lou)梯(ti)(ti)適用(yong)于(yu)(yu)可變荷載較小、梯(ti)(ti)段(duan)(duan)(duan)板(ban)(ban)(ban)(ban)跨度一般不大(da)(da)于(yu)(yu)3m的情況。
