建筑物中作為(wei)樓(lou)層間交通用的(de)構件(jian)。由連(lian)續梯(ti)(ti)級的(de)梯(ti)(ti)段、平臺(tai)和圍護結構等(deng)組成。在(zai)設(she)電梯(ti)(ti)的(de)高層建筑中也同(tong)樣必須設(she)置樓(lou)梯(ti)(ti)。樓(lou)梯(ti)(ti)分普通樓(lou)梯(ti)(ti)和特種樓(lou)梯(ti)(ti)兩大類。普通樓(lou)梯(ti)(ti)包括鋼筋混凝(ning)土(tu)樓(lou)梯(ti)(ti)、鋼樓(lou)梯(ti)(ti)和木樓(lou)梯(ti)(ti)等(deng)，其中鋼筋混凝(ning)土(tu)樓(lou)梯(ti)(ti)在(zai)結構剛度、耐火、造價、施工、造型(xing)等(deng)方面具有(you)較多的(de)優點，應(ying)用最為(wei)普遍。特種樓(lou)梯(ti)(ti)主要有(you)安全梯(ti)(ti)、消防梯(ti)(ti)和自動梯(ti)(ti)3種。

按照空間可劃分為室(shi)內樓(lou)(lou)(lou)梯(ti)(ti)(ti)(ti)和室(shi)外(wai)樓(lou)(lou)(lou)梯(ti)(ti)(ti)(ti)。室(shi)內樓(lou)(lou)(lou)梯(ti)(ti)(ti)(ti)，字面已經解釋清楚，應(ying)(ying)用(yong)與各種住宅內部，因追求室(shi)內美觀舒適，室(shi)內樓(lou)(lou)(lou)梯(ti)(ti)(ti)(ti)多以實(shi)(shi)木(mu)(mu)樓(lou)(lou)(lou)梯(ti)(ti)(ti)(ti)，鋼木(mu)(mu)樓(lou)(lou)(lou)梯(ti)(ti)(ti)(ti)，鋼與玻璃，鋼筋混凝土(tu)等或多種混合材質為主，其中(zhong)實(shi)(shi)木(mu)(mu)樓(lou)(lou)(lou)梯(ti)(ti)(ti)(ti)是高(gao)檔住宅內應(ying)(ying)用(yong)最廣泛(fan)(fan)的樓(lou)(lou)(lou)梯(ti)(ti)(ti)(ti)，鋼與玻璃混合結構樓(lou)(lou)(lou)梯(ti)(ti)(ti)(ti)在現代辦公區，寫字樓(lou)(lou)(lou)，商場(chang)，展廳(ting)等應(ying)(ying)用(yong)居多，鋼筋混凝土(tu)樓(lou)(lou)(lou)梯(ti)(ti)(ti)(ti)廣泛(fan)(fan)應(ying)(ying)用(yong)于各種復(fu)式(shi)建筑(zhu)中(zhong)。室(shi)外(wai)樓(lou)(lou)(lou)梯(ti)(ti)(ti)(ti)因為考慮到風吹雨曬等自然因素，一般外(wai)形美觀的實(shi)(shi)木(mu)(mu)樓(lou)(lou)(lou)梯(ti)(ti)(ti)(ti)，鋼木(mu)(mu)樓(lou)(lou)(lou)梯(ti)(ti)(ti)(ti)，金屬樓(lou)(lou)(lou)梯(ti)(ti)(ti)(ti)等就不(bu)太適宜，鋼筋混凝土(tu)樓(lou)(lou)(lou)梯(ti)(ti)(ti)(ti)，各種石(shi)材樓(lou)(lou)(lou)梯(ti)(ti)(ti)(ti)最為常(chang)見。
