按結(jie)構(gou)形(xing)式(shi)(shi)和(he)受力特點樓梯形(xing)式(shi)(shi)可分為板式(shi)(shi)、梁式(shi)(shi)、懸挑(剪刀)式(shi)(shi)和(he)螺(luo)旋式(shi)(shi)，前兩種屬(shu)于平面受力體(ti)系，后兩種則為空間受力體(ti)系。

板(ban)(ban)式樓(lou)梯(ti)(ti)(ti)(ti)是(shi)由梯(ti)(ti)(ti)(ti)段(duan)(duan)板(ban)(ban)、平臺板(ban)(ban)和平臺梁組成。梯(ti)(ti)(ti)(ti)段(duan)(duan)板(ban)(ban)是(shi)一塊(kuai)帶(dai)踏步的斜板(ban)(ban)，斜板(ban)(ban)支(zhi)承于(yu)上(shang)、下平臺梁上(shang)，底(di)層(ceng)下端支(zhi)承在(zai)地壟墻上(shang)。板(ban)(ban)式樓(lou)梯(ti)(ti)(ti)(ti)的優點是(shi)梯(ti)(ti)(ti)(ti)段(duan)(duan)板(ban)(ban)下表面平整，支(zhi)模簡單;其缺點是(shi)梯(ti)(ti)(ti)(ti)段(duan)(duan)板(ban)(ban)跨(kua)度較大(da)時，斜板(ban)(ban)厚度較大(da)，結構(gou)材料用量較多。因此板(ban)(ban)式樓(lou)梯(ti)(ti)(ti)(ti)適用于(yu)可變荷(he)載較小、梯(ti)(ti)(ti)(ti)段(duan)(duan)板(ban)(ban)跨(kua)度一般不大(da)于(yu)3m的情況。
