按結構(gou)形式(shi)和(he)受力特(te)點樓梯形式(shi)可(ke)分(fen)為板式(shi)、梁式(shi)、懸挑(tiao)(剪刀)式(shi)和(he)螺(luo)旋式(shi)，前兩(liang)種(zhong)屬于平(ping)面(mian)受力體系，后兩(liang)種(zhong)則(ze)為空(kong)間(jian)受力體系。

板(ban)(ban)(ban)(ban)(ban)式(shi)(shi)樓梯(ti)是由梯(ti)段(duan)(duan)板(ban)(ban)(ban)(ban)(ban)、平(ping)(ping)(ping)臺(tai)板(ban)(ban)(ban)(ban)(ban)和平(ping)(ping)(ping)臺(tai)梁組成。梯(ti)段(duan)(duan)板(ban)(ban)(ban)(ban)(ban)是一塊(kuai)帶(dai)踏步的(de)斜(xie)板(ban)(ban)(ban)(ban)(ban)，斜(xie)板(ban)(ban)(ban)(ban)(ban)支承于(yu)上、下(xia)平(ping)(ping)(ping)臺(tai)梁上，底層下(xia)端支承在地(di)壟墻上。板(ban)(ban)(ban)(ban)(ban)式(shi)(shi)樓梯(ti)的(de)優點是梯(ti)段(duan)(duan)板(ban)(ban)(ban)(ban)(ban)下(xia)表面平(ping)(ping)(ping)整，支模簡單;其(qi)缺(que)點是梯(ti)段(duan)(duan)板(ban)(ban)(ban)(ban)(ban)跨度較大時，斜(xie)板(ban)(ban)(ban)(ban)(ban)厚(hou)度較大，結構材料用量較多(duo)。因此板(ban)(ban)(ban)(ban)(ban)式(shi)(shi)樓梯(ti)適用于(yu)可變荷載較小、梯(ti)段(duan)(duan)板(ban)(ban)(ban)(ban)(ban)跨度一般不(bu)大于(yu)3m的(de)情況。
