理由是現澆樓梯跟建筑本體結合的更好，強度穩定性非常好，但是缺點是一旦成形，不能更改造型，樓梯扶手只能按照現澆樓梯的造型設計，所以導致很多樓梯落差設計不合理，安裝扶手不是很流暢優美。而整體樓梯則與之相反！
The reason is that the cast-in-place stairs are better integrated with the building itself, and the strength and stability are very good. But the disadvantage is that once formed, the shape can not be changed. lvyouji.89ix.comguolvq.89ix.comguolvqil.89ix.comkongzhifay.89ix.comyalvji.89ix.comzhafab.89ix.comThe handrails of stairs can only be designed according to the shape of cast-in-place stairs, which leads to unreasonable design of many stairs, and the installation of handrails is not smooth and graceful. The whole staircase is the opposite!
