按結構(gou)形式(shi)(shi)和受力特(te)點樓梯形式(shi)(shi)可(ke)分為板式(shi)(shi)、梁式(shi)(shi)、懸挑(剪刀(dao))式(shi)(shi)和螺旋式(shi)(shi)，前兩種屬(shu)于平面受力體系，后(hou)兩種則為空間受力體系。

板(ban)(ban)(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)是由梯(ti)(ti)段板(ban)(ban)(ban)(ban)(ban)、平臺(tai)板(ban)(ban)(ban)(ban)(ban)和平臺(tai)梁(liang)組成(cheng)。梯(ti)(ti)段板(ban)(ban)(ban)(ban)(ban)是一(yi)塊帶踏步的(de)(de)斜板(ban)(ban)(ban)(ban)(ban)，斜板(ban)(ban)(ban)(ban)(ban)支(zhi)承(cheng)于上(shang)、下(xia)平臺(tai)梁(liang)上(shang)，底層下(xia)端支(zhi)承(cheng)在地壟墻上(shang)。板(ban)(ban)(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)的(de)(de)優點(dian)(dian)是梯(ti)(ti)段板(ban)(ban)(ban)(ban)(ban)下(xia)表面平整，支(zhi)模(mo)簡單(dan);其缺點(dian)(dian)是梯(ti)(ti)段板(ban)(ban)(ban)(ban)(ban)跨度較(jiao)大時，斜板(ban)(ban)(ban)(ban)(ban)厚(hou)度較(jiao)大，結(jie)構材(cai)料用量較(jiao)多。因此板(ban)(ban)(ban)(ban)(ban)式(shi)樓(lou)梯(ti)(ti)適用于可變(bian)荷載較(jiao)小、梯(ti)(ti)段板(ban)(ban)(ban)(ban)(ban)跨度一(yi)般(ban)不大于3m的(de)(de)情(qing)況。
