按結構(gou)形式(shi)(shi)(shi)(shi)和(he)受力(li)特(te)點樓梯形式(shi)(shi)(shi)(shi)可分為(wei)板式(shi)(shi)(shi)(shi)、梁式(shi)(shi)(shi)(shi)、懸挑(剪刀)式(shi)(shi)(shi)(shi)和(he)螺旋式(shi)(shi)(shi)(shi)，前兩(liang)(liang)種(zhong)屬于平(ping)面(mian)受力(li)體(ti)系，后兩(liang)(liang)種(zhong)則為(wei)空間受力(li)體(ti)系。

板(ban)(ban)(ban)(ban)式樓(lou)梯(ti)(ti)(ti)(ti)是由梯(ti)(ti)(ti)(ti)段板(ban)(ban)(ban)(ban)、平(ping)(ping)臺(tai)板(ban)(ban)(ban)(ban)和平(ping)(ping)臺(tai)梁組成(cheng)。梯(ti)(ti)(ti)(ti)段板(ban)(ban)(ban)(ban)是一塊帶踏步的(de)斜板(ban)(ban)(ban)(ban)，斜板(ban)(ban)(ban)(ban)支承(cheng)于上(shang)、下(xia)平(ping)(ping)臺(tai)梁上(shang)，底層下(xia)端(duan)支承(cheng)在地壟墻上(shang)。板(ban)(ban)(ban)(ban)式樓(lou)梯(ti)(ti)(ti)(ti)的(de)優點是梯(ti)(ti)(ti)(ti)段板(ban)(ban)(ban)(ban)下(xia)表面(mian)平(ping)(ping)整，支模簡(jian)單;其缺點是梯(ti)(ti)(ti)(ti)段板(ban)(ban)(ban)(ban)跨(kua)度(du)較(jiao)(jiao)大時，斜板(ban)(ban)(ban)(ban)厚度(du)較(jiao)(jiao)大，結構材料用量較(jiao)(jiao)多(duo)。因此板(ban)(ban)(ban)(ban)式樓(lou)梯(ti)(ti)(ti)(ti)適用于可變荷載(zai)較(jiao)(jiao)小、梯(ti)(ti)(ti)(ti)段板(ban)(ban)(ban)(ban)跨(kua)度(du)一般不大于3m的(de)情況。
