按結構(gou)形式(shi)和受力(li)(li)特(te)點樓梯形式(shi)可(ke)分為板式(shi)、梁式(shi)、懸挑(剪刀(dao))式(shi)和螺旋(xuan)式(shi)，前兩種(zhong)屬于(yu)平面受力(li)(li)體系，后兩種(zhong)則(ze)為空間(jian)受力(li)(li)體系。

板(ban)(ban)式(shi)樓(lou)梯(ti)(ti)是由梯(ti)(ti)段(duan)(duan)(duan)板(ban)(ban)、平(ping)臺板(ban)(ban)和平(ping)臺梁(liang)組成。梯(ti)(ti)段(duan)(duan)(duan)板(ban)(ban)是一(yi)塊帶踏(ta)步(bu)的斜板(ban)(ban)，斜板(ban)(ban)支承于上、下平(ping)臺梁(liang)上，底(di)層下端支承在(zai)地壟(long)墻上。板(ban)(ban)式(shi)樓(lou)梯(ti)(ti)的優點是梯(ti)(ti)段(duan)(duan)(duan)板(ban)(ban)下表面平(ping)整，支模(mo)簡單(dan);其缺點是梯(ti)(ti)段(duan)(duan)(duan)板(ban)(ban)跨度(du)較(jiao)大(da)時，斜板(ban)(ban)厚度(du)較(jiao)大(da)，結(jie)構(gou)材(cai)料用量較(jiao)多(duo)。因此板(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)跨度(du)一(yi)般不大(da)于3m的情況。
