按結構(gou)形式(shi)和受力(li)(li)特點樓梯形式(shi)可分為板式(shi)、梁(liang)式(shi)、懸挑(剪刀)式(shi)和螺(luo)旋(xuan)式(shi)，前(qian)兩(liang)種(zhong)屬(shu)于平面受力(li)(li)體(ti)系，后(hou)兩(liang)種(zhong)則為空(kong)間受力(li)(li)體(ti)系。

板(ban)(ban)(ban)(ban)式(shi)(shi)樓(lou)梯(ti)(ti)(ti)是(shi)(shi)由梯(ti)(ti)(ti)段(duan)(duan)板(ban)(ban)(ban)(ban)、平(ping)臺板(ban)(ban)(ban)(ban)和(he)平(ping)臺梁(liang)組成。梯(ti)(ti)(ti)段(duan)(duan)板(ban)(ban)(ban)(ban)是(shi)(shi)一塊帶踏步的斜(xie)板(ban)(ban)(ban)(ban)，斜(xie)板(ban)(ban)(ban)(ban)支承(cheng)于(yu)上、下平(ping)臺梁(liang)上，底層下端支承(cheng)在地壟墻上。板(ban)(ban)(ban)(ban)式(shi)(shi)樓(lou)梯(ti)(ti)(ti)的優點是(shi)(shi)梯(ti)(ti)(ti)段(duan)(duan)板(ban)(ban)(ban)(ban)下表面平(ping)整，支模簡單;其(qi)缺點是(shi)(shi)梯(ti)(ti)(ti)段(duan)(duan)板(ban)(ban)(ban)(ban)跨度較大時(shi)，斜(xie)板(ban)(ban)(ban)(ban)厚度較大，結構材料用量較多。因此(ci)板(ban)(ban)(ban)(ban)式(shi)(shi)樓(lou)梯(ti)(ti)(ti)適用于(yu)可(ke)變荷載較小、梯(ti)(ti)(ti)段(duan)(duan)板(ban)(ban)(ban)(ban)跨度一般不大于(yu)3m的情(qing)況(kuang)。
