现浇顶如何养护
在初凝以后开始覆盖养护,在终凝后开始浇水(12小时后)覆盖物、麦杆、烂草席、竹帘、麻袋片、编制布等片状物。
浇水工具可以采用水管、水桶等工具保证砼的湿润度。
养护时间,与构件项目、水泥品种和有无掺外加济有关,常用的五种水泥正温条件下应不少与7天;掺有外加剂或有抗渗、抗冻要求的项目,应不少与14天
还有就是喷摸养护
工具农用喷雾器
养护时间一样
无论是柱子还是梁都是一样的
楼板也是
打现浇顶需要注意什么
首先,因您是自用房,前提该是坚固安全,尤其还要做
屋顶花园
,所提建议可能有些费事费钱,请您理解。
一、建议您选用抗渗砼(C25S8~C30S8)浇筑
屋面板
,如您所在地有
商品砼
供应,更好选用商品砼。因抗渗砼须添加
外加剂
,现场搅拌砼的配合比和外加剂用量较难保证。如必须现场搅拌,砼所用
水泥标号
应为42.5;石子要干净,更好过一遍筛,粒径不要太大,13~19mm为宜;砂应选用含土量少的优质砂。外加剂可选用
木钙
,其用法和用量应按照
产品说明书
严格掌握。
二、不知您的屋面板跨度多少,不好说屋面
现浇板
厚度。请您掌握这个比值:板的厚度宜取其跨度的1/30~1/35。
三、同样原因,板的配筋在这里无法告知您,请您在当地请一位懂行的人计算一下更好。单单计算这点儿,花不了几个钱,但安全,您说对吧。绑钢筋时注意不要顺扣(主要指上排负弯矩钢筋)。
四、防水作法建议采用
三元乙丙
或
SBS卷材
,更好请专业人员施工。否则,建成后出问题检修时很头疼的。注意,必须等屋面板和砂浆
找平层
干透以后方可进行
防水层
施工。
五、更好在防水层上部现浇40mm厚细石砼,并配φ6@250
双向钢筋
。
其他的可根据您自己的想法,进行装修施工。不知是否符合您的意图,做个参考吧,
祝您幸福。
什么是现浇顶房子
预制板是先在地上浇注好一块块的组件,然后放在梁上组装成楼板,上面会再做一层河沙水泥;现浇是在工地上加模具直接用混凝土浇注整体成型的楼板。
后者的安全性更高,在地震中预制板会义无反顾的到处乱砸,现浇的就不会。
