按結(jie)構形式和(he)(he)受力特(te)點樓梯(ti)形式可(ke)分為板式、梁式、懸(xuan)挑(剪刀)式和(he)(he)螺(luo)旋式，前(qian)兩(liang)種屬于平(ping)面受力體系，后兩(liang)種則(ze)為空間受力體系。

板(ban)(ban)(ban)(ban)式樓(lou)梯(ti)(ti)(ti)是(shi)由梯(ti)(ti)(ti)段(duan)板(ban)(ban)(ban)(ban)、平臺(tai)板(ban)(ban)(ban)(ban)和平臺(tai)梁組成。梯(ti)(ti)(ti)段(duan)板(ban)(ban)(ban)(ban)是(shi)一塊帶踏步的斜(xie)板(ban)(ban)(ban)(ban)，斜(xie)板(ban)(ban)(ban)(ban)支(zhi)承于上(shang)(shang)、下(xia)平臺(tai)梁上(shang)(shang)，底(di)層下(xia)端支(zhi)承在地壟墻上(shang)(shang)。板(ban)(ban)(ban)(ban)式樓(lou)梯(ti)(ti)(ti)的優點是(shi)梯(ti)(ti)(ti)段(duan)板(ban)(ban)(ban)(ban)下(xia)表面平整，支(zhi)模(mo)簡單;其缺點是(shi)梯(ti)(ti)(ti)段(duan)板(ban)(ban)(ban)(ban)跨度(du)較大時，斜(xie)板(ban)(ban)(ban)(ban)厚度(du)較大，結(jie)構(gou)材料用(yong)量較多。因此(ci)板(ban)(ban)(ban)(ban)式樓(lou)梯(ti)(ti)(ti)適用(yong)于可(ke)變(bian)荷(he)載較小、梯(ti)(ti)(ti)段(duan)板(ban)(ban)(ban)(ban)跨度(du)一般不大于3m的情況。
