1,、承重墻打掉20公分可以嗎

最好不要打掉承重墻,。一,承重墻指支撐著上部樓層重量的墻體,那是支撐建筑的脊梁。承重墻是決定室內安全的一個重要部分,。原則上承重墻是不可以打洞或損壞的!二,在新房裝修時,物業(yè)往往會要求業(yè)主繳納一定的裝修押金,其目的就是為了防止業(yè)主在裝修時破壞承重墻和樓體結構,造成樓房質量隱患和使用壽命的縮短,。三,裝修需注意事項:1,改動承重墻會影響樓體安全對于一個房子的避震風險來說,最重要的是樓盤的土建結構要過關,這是最基礎的一點。在裝修的時候,結構改造一定要合理,要根據房屋的原始結構進行改造,一定不能改動到房屋的承重墻,最好不要過于追求效果而拆除墻體,不能隨意野蠻的對房屋結構進行改造,。很多建筑結構是非常系統(tǒng)的,拆除一面墻可能會使整個樓體的安全性都受到影響,。改造房屋要以房屋的原始結構為依據,在承重方面,不同結構的房屋類型每平方米的承重是不同的。2,拆配重墻會降低房間牢固性承重墻不能動,很多人都知道,對配重墻來說,拆除雖不會對房屋結構產生重大影響,但卻會降低房屋的牢固性,。配重墻一般在客廳和陽臺之間,這類墻體原則上可以動,但設計師并不建議業(yè)主拆除,拆除配重墻會增加承重墻的負荷,從而會使房屋的牢固性大大降低,。但是對厚度小于11厘米的隔斷來說,只起到隔離空間的作用,所以拆除對房屋影響并不大。3,衛(wèi)生間原有建筑設計利于防震相對來說,衛(wèi)生間和玄關更堅固一些,因此裝修時應該保持衛(wèi)生間和玄關的原有建筑設計,?！靶l(wèi)生間的空間比較小,衛(wèi)生間里也有下水管等一些管道,可以對房屋形成一定的支撐。衛(wèi)生間能成為暫時避難的地方,主要還是因為空間小,、框架小,就算地震來的時候也較其他地方不容易倒塌,。而且,人的生存最需要的是水,衛(wèi)生間有充足的水,萬一因為房屋倒塌,人被封閉到里邊也不怕。玄關因為空間小,、框架小,、不易倒塌,所以也可以作為暫時的避險場所,但防震抗震主要還是得依靠房屋本身的土建結構?！?img
