楼板厚度
楼板通常厚度在8-12厘米。
实际建筑中,由于建筑设计、施工标准不同,也会有所不同。楼板内嵌入暗管,楼板厚度需达到12厘米。
楼板;
是指楼房两层之间的隔板。
一种分隔承重构件。楼板层中的承重部分,它将房屋垂直方向分隔为若干层,并把人和家具等竖向荷载及楼板自重通过墙体、梁或柱传给基础。
按其所用的材料可分为木楼板、砖拱楼板、钢筋混凝土楼板和钢衬板承重的楼板等几种形式。
如果是顶层的楼板,厚度也要达到12厘米,毕竟顶层暴露在外,要经受风吹雨打。3、如果是开间进深的楼房,楼板厚度要在8-10厘米间。
楼板厚度一般是多少
100-120mm厚。依据高层建筑混凝土结构技术规程JGJ3-2002:JGJ3-2002中规定:
高层建筑楼板厚度一般是100-120mm厚,特别大的跨度可以用到150--180厚。多层的一般现浇的大约80~120MM,商业有的为150MM。
预制板有实心和空心两种。 *** 空心预制板的目的,简单的说是因为在板的空心的位置不受力,所以在空心的地方灌注混凝土就没有用,于是就可以把不受力的地方空起来,达到减轻重量和节省造价的目的。
但是已经不提倡用预制空心板,楼房结构都采用现浇结构,好处是造出来的房子整体性好,也就是说更结实了。
扩展资料:
其实用预制板也有它的好处所在,比如说缩短工期,减少造价等等。预制空心板(YKB)并不是都不承重,在板头处也要承受上面的荷载,所以在板头加上堵头,YKB板缝也有一定的规定,一般是小于30不合格,30-50合格,50-110板缝加筋。
大于110小于500(超过一个板的标志长度,可以选择加一块板,板的标志长度500、600、900)做成板带。注:此处板缝是指板平放板下面的缝隙。(板规格上面比下面窄20)。

楼板的厚度是什么?
根据国家的规定,如果是商品房,那么楼板的厚度一般来说不能够小于60毫米。而有些商品房建造的时候选择的是双层双向钢筋,这种楼板的厚度一般来说不能够小于80毫米。有一种是没有横梁的楼板,对于它的厚度要求会更加高,厚度低于了150毫米,那么承受力肯定达不到标准,必须要在150以上。
楼板的厚度其实与楼房的高度也有直接的关系,我们可以通过楼房的高度来判断,一般来说出售的商品房高度不能低于2.8米,而新房装修之后因为吊了顶,实际只有2.4米左右,所以楼板的厚度与2.4米有直接的关系,如果有误差也是允许的,但是误差范围不能够太大。
楼板施工注意事项
在施工中,要注重楼板的施工质量,要严格按照图纸的要求、尺寸等来施工,要严格遵从施工步骤,这样能更好的保证施工质量,避免出现返工等问题。建议在施工前,选择正规、专业性强的施工团队,这样能更好的保障施工质量。
在施工中,要重视对每个步骤的验收。在验收时,要仔细认真,要认真检查各个边角施工质量是否合格,若存在不足之处,需及时修补或整改,避免影响下道工序的进行,也避免留下安全隐患。要等上道工序验收合格后,才能进行下道工序。
