按結構(gou)形(xing)式(shi)和受力特點樓梯形(xing)式(shi)可(ke)分為板式(shi)、梁式(shi)、懸挑(tiao)(剪刀)式(shi)和螺旋(xuan)式(shi)，前兩種屬于平面(mian)受力體(ti)系，后兩種則為空間(jian)受力體(ti)系。

板(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)是由梯(ti)(ti)段(duan)板(ban)(ban)(ban)、平(ping)臺(tai)板(ban)(ban)(ban)和平(ping)臺(tai)梁組成。梯(ti)(ti)段(duan)板(ban)(ban)(ban)是一塊(kuai)帶踏步(bu)的(de)斜(xie)板(ban)(ban)(ban)，斜(xie)板(ban)(ban)(ban)支承于(yu)上、下平(ping)臺(tai)梁上，底(di)層(ceng)下端支承在(zai)地壟墻(qiang)上。板(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)的(de)優(you)點(dian)是梯(ti)(ti)段(duan)板(ban)(ban)(ban)下表面平(ping)整，支模簡單;其(qi)缺點(dian)是梯(ti)(ti)段(duan)板(ban)(ban)(ban)跨(kua)度(du)較(jiao)(jiao)大時，斜(xie)板(ban)(ban)(ban)厚(hou)度(du)較(jiao)(jiao)大，結構材料用量較(jiao)(jiao)多。因此板(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)適用于(yu)可變荷載較(jiao)(jiao)小(xiao)、梯(ti)(ti)段(duan)板(ban)(ban)(ban)跨(kua)度(du)一般不(bu)大于(yu)3m的(de)情況。
