问题 问答题 简答题

装修中,哪些是不能拆除或需要慎重的地方?

答案

参考答案:

1.承重墙:装修中不能拆改承重墙。什么样的墙是承重墙?一般在“砖混”结构的建筑物中,凡是预制板墙一律不能拆除或开门开窗;厚度超过24厘米以上的砖墙,也不能拆改,这些都属于承重墙。

2.墙体中的钢筋:在埋设管线时如将钢筋破坏,就会影响到墙体和楼板的承受力。如果遇到地震,这样的墙体和楼板就很容易崩塌、断裂。

3.房间中的梁柱:梁柱是用来支撑上层楼板的,拆掉后上层楼板就会掉下来,所以也不能动。

4.阳台边的矮墙:一般房间与阳台之间都有一门一窗。这些门窗都可以拆改,但窗以下的墙不能动。这段墙叫“配重墙”,它像秤砣一样起着挑起阳台的作用。拆改这堵墙,会使阳台的承重力下降,导致阳台下坠。

5.户门:户门的门框是嵌在混泥土中的,如果拆改,会破坏建筑结构,降低安全系数。而且破坏了门口的建筑结构,重新安装新门就更加困难了。6.卫生间和厨房的防水层:这些地方的地面下都有防水层,如果破坏了,楼下就会变成“水帘洞”。如果破坏后重新修建,一定要做“24小时渗水实验”。
