按結構(gou)形(xing)式(shi)和受力(li)特(te)點樓梯(ti)形(xing)式(shi)可(ke)分為板(ban)式(shi)、梁式(shi)、懸挑(剪刀)式(shi)和螺旋式(shi)，前兩種屬(shu)于(yu)平面(mian)受力(li)體(ti)系，后兩種則為空間受力(li)體(ti)系。

板(ban)(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)是(shi)由梯(ti)(ti)段板(ban)(ban)(ban)(ban)、平(ping)臺板(ban)(ban)(ban)(ban)和(he)平(ping)臺梁組(zu)成。梯(ti)(ti)段板(ban)(ban)(ban)(ban)是(shi)一塊(kuai)帶踏步的(de)斜(xie)板(ban)(ban)(ban)(ban)，斜(xie)板(ban)(ban)(ban)(ban)支(zhi)承于(yu)上(shang)、下平(ping)臺梁上(shang)，底層下端(duan)支(zhi)承在地壟墻(qiang)上(shang)。板(ban)(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)的(de)優點是(shi)梯(ti)(ti)段板(ban)(ban)(ban)(ban)下表面平(ping)整，支(zhi)模(mo)簡單;其缺點是(shi)梯(ti)(ti)段板(ban)(ban)(ban)(ban)跨(kua)度(du)較(jiao)大(da)時，斜(xie)板(ban)(ban)(ban)(ban)厚(hou)度(du)較(jiao)大(da)，結構材料用量較(jiao)多。因此(ci)板(ban)(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)適(shi)用于(yu)可變荷(he)載較(jiao)小、梯(ti)(ti)段板(ban)(ban)(ban)(ban)跨(kua)度(du)一般不大(da)于(yu)3m的(de)情況。
