按結構形式(shi)(shi)(shi)和受力(li)特點樓梯形式(shi)(shi)(shi)可分為板式(shi)(shi)(shi)、梁式(shi)(shi)(shi)、懸挑(tiao)(剪刀)式(shi)(shi)(shi)和螺(luo)旋式(shi)(shi)(shi)，前兩種屬于平面受力(li)體系(xi)，后(hou)兩種則為空間(jian)受力(li)體系(xi)。

板(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)(ti)是由梯(ti)(ti)(ti)段(duan)(duan)板(ban)(ban)(ban)、平(ping)(ping)臺(tai)(tai)板(ban)(ban)(ban)和平(ping)(ping)臺(tai)(tai)梁(liang)(liang)組成。梯(ti)(ti)(ti)段(duan)(duan)板(ban)(ban)(ban)是一(yi)塊帶踏步的(de)斜板(ban)(ban)(ban)，斜板(ban)(ban)(ban)支承于上(shang)、下(xia)平(ping)(ping)臺(tai)(tai)梁(liang)(liang)上(shang)，底層(ceng)下(xia)端支承在地壟墻上(shang)。板(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)(ti)的(de)優點(dian)是梯(ti)(ti)(ti)段(duan)(duan)板(ban)(ban)(ban)下(xia)表面平(ping)(ping)整，支模簡單;其缺(que)點(dian)是梯(ti)(ti)(ti)段(duan)(duan)板(ban)(ban)(ban)跨度(du)較大(da)時(shi)，斜板(ban)(ban)(ban)厚度(du)較大(da)，結構材(cai)料(liao)用量較多。因此板(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)(ti)適用于可變荷載較小、梯(ti)(ti)(ti)段(duan)(duan)板(ban)(ban)(ban)跨度(du)一(yi)般不(bu)大(da)于3m的(de)情況。
