按結構形式(shi)和受(shou)力特(te)點樓梯形式(shi)可分(fen)為(wei)板式(shi)、梁(liang)式(shi)、懸挑(剪刀)式(shi)和螺旋(xuan)式(shi)，前兩(liang)種(zhong)屬(shu)于平面受(shou)力體系，后兩(liang)種(zhong)則為(wei)空間受(shou)力體系。

板(ban)(ban)式樓(lou)梯(ti)(ti)是(shi)由(you)梯(ti)(ti)段板(ban)(ban)、平臺(tai)板(ban)(ban)和平臺(tai)梁組成。梯(ti)(ti)段板(ban)(ban)是(shi)一塊(kuai)帶踏步的斜板(ban)(ban)，斜板(ban)(ban)支承于上(shang)、下平臺(tai)梁上(shang)，底層下端支承在地(di)壟(long)墻(qiang)上(shang)。板(ban)(ban)式樓(lou)梯(ti)(ti)的優點(dian)是(shi)梯(ti)(ti)段板(ban)(ban)下表面平整，支模簡(jian)單;其缺(que)點(dian)是(shi)梯(ti)(ti)段板(ban)(ban)跨度(du)較(jiao)大時，斜板(ban)(ban)厚(hou)度(du)較(jiao)大，結構材料用量(liang)較(jiao)多(duo)。因此板(ban)(ban)式樓(lou)梯(ti)(ti)適用于可(ke)變荷載較(jiao)小、梯(ti)(ti)段板(ban)(ban)跨度(du)一般不大于3m的情況。
