按結構形式(shi)(shi)和受力特點(dian)樓梯形式(shi)(shi)可(ke)分為板式(shi)(shi)、梁式(shi)(shi)、懸挑(剪刀)式(shi)(shi)和螺旋式(shi)(shi)，前兩種(zhong)屬于(yu)平面受力體(ti)(ti)系(xi)(xi)，后兩種(zhong)則為空間受力體(ti)(ti)系(xi)(xi)。
板(ban)(ban)式(shi)樓(lou)(lou)梯(ti)是(shi)由梯(ti)段(duan)板(ban)(ban)、平(ping)臺板(ban)(ban)和平(ping)臺梁組成。梯(ti)段(duan)板(ban)(ban)是(shi)一塊帶踏步的斜板(ban)(ban)，斜板(ban)(ban)支(zhi)承于(yu)上、下(xia)(xia)平(ping)臺梁上，底層下(xia)(xia)端(duan)支(zhi)承在地壟墻上。板(ban)(ban)式(shi)樓(lou)(lou)梯(ti)的優點是(shi)梯(ti)段(duan)板(ban)(ban)下(xia)(xia)表面平(ping)整，支(zhi)模簡單;其(qi)缺點是(shi)梯(ti)段(duan)板(ban)(ban)跨(kua)度較大時(shi)，斜板(ban)(ban)厚度較大，結構材料用量較多。因此(ci)板(ban)(ban)式(shi)樓(lou)(lou)梯(ti)適(shi)用于(yu)可變荷載較小、梯(ti)段(duan)板(ban)(ban)跨(kua)度一般不大于(yu)3m的情況。
