按結(jie)構形式(shi)和(he)受力特點樓梯形式(shi)可分為(wei)板式(shi)、梁式(shi)、懸挑(剪刀(dao))式(shi)和(he)螺旋式(shi)，前兩(liang)種屬于平面受力體(ti)系，后兩(liang)種則為(wei)空(kong)間受力體(ti)系。

板(ban)(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)是由(you)梯(ti)(ti)段(duan)(duan)(duan)板(ban)(ban)(ban)(ban)、平(ping)(ping)臺板(ban)(ban)(ban)(ban)和平(ping)(ping)臺梁組成。梯(ti)(ti)段(duan)(duan)(duan)板(ban)(ban)(ban)(ban)是一(yi)塊(kuai)帶踏步(bu)的斜(xie)板(ban)(ban)(ban)(ban)，斜(xie)板(ban)(ban)(ban)(ban)支承于上(shang)、下(xia)平(ping)(ping)臺梁上(shang)，底層下(xia)端支承在地壟墻上(shang)。板(ban)(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)的優(you)點是梯(ti)(ti)段(duan)(duan)(duan)板(ban)(ban)(ban)(ban)下(xia)表面平(ping)(ping)整，支模簡單;其(qi)缺(que)點是梯(ti)(ti)段(duan)(duan)(duan)板(ban)(ban)(ban)(ban)跨(kua)度(du)較(jiao)大(da)時，斜(xie)板(ban)(ban)(ban)(ban)厚度(du)較(jiao)大(da)，結構材料用量較(jiao)多。因此板(ban)(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)適(shi)用于可變荷載較(jiao)小、梯(ti)(ti)段(duan)(duan)(duan)板(ban)(ban)(ban)(ban)跨(kua)度(du)一(yi)般不(bu)大(da)于3m的情況。
