承重墻上可以開(kāi)洞嗎
1、一般情況下:家裝過(guò)程中,一般承重墻是禁止開(kāi)洞的,不僅違法,而且有一定的風(fēng)險(xiǎn),因?yàn)槌兄貕Τ袚?dān)著房屋的重量,如果在拆了或者開(kāi)洞,會(huì)失去原有的作用,降低了墻體的抗震性能,設(shè)計(jì)的時(shí)候這種力是由各段墻體均衡分擔(dān)的,當(dāng)局部墻體拆除后,地震時(shí)作用在該墻體上的剪力就如到鄰近墻體上,造成鄰近墻體負(fù)擔(dān)過(guò)重或在洞口附近產(chǎn)生應(yīng)力集中,導(dǎo)致墻體過(guò)早開(kāi)裂而破壞。2、特殊情況:如果非要開(kāi)洞的話(huà),也不是完全不可以,但是要考慮以下幾種因素。建設(shè)部有規(guī)定,要改造承重墻的話(huà),再比如由原設(shè)計(jì)單位、或者與原設(shè)計(jì)單位具有相同資質(zhì)的設(shè)計(jì)單位給出修改、加固設(shè)計(jì)方案,方可對(duì)承重墻進(jìn)行拆改。也就是說(shuō),單從技術(shù)角度考慮,要開(kāi)窗也可以;但是一定要縮小在一定范圍之內(nèi),而且要進(jìn)行加固完成,通常采用的加固方法為。粘鋼或碳纖維等,但這個(gè)加固方案及拆除施工作業(yè)均必須要由具備相應(yīng)資質(zhì)的單位來(lái)完成,而且還要是在物業(yè)允許的情況下,但一定要嵌入槽鋼,而且,窗戶(hù)不宜過(guò)大。其次,還是建議大家不要隨便拆改承重墻,一方面是因?yàn)椴鸶牟皇且患菀椎氖虑?其次設(shè)計(jì)很多方面,如果拆改不注意,會(huì)破壞房屋結(jié)構(gòu),造成安全隱患,甚至遭到投訴。
承重墻開(kāi)洞加固怎么做
混凝土墻體開(kāi)洞后，如果開(kāi)洞很少且洞口不大，不用加固，開(kāi)洞較多或洞口較大，一般用粘貼碳纖維的方法加固。
磚墻開(kāi)洞方法
方法：1、墻體中開(kāi)門(mén)洞，首先需要確定開(kāi)洞位置，如果是承重墻，考慮清楚千萬(wàn)不能夠亂砸墻、亂開(kāi)洞，如果非要開(kāi)，還需要提前做好加固的處理，并且要到物業(yè)公司進(jìn)行報(bào)備，甚至還需要通過(guò)有關(guān)部門(mén)辦理審批的手續(xù)，才能夠開(kāi)門(mén)洞，要不然很容易對(duì)于房屋的結(jié)構(gòu)造成損壞。2、在允許的前提條件下，我們?cè)俅_定開(kāi)門(mén)洞的位置，通過(guò)水鉆來(lái)排孔。再進(jìn)行拆除的工程，為了減少現(xiàn)場(chǎng)的粉塵對(duì)工作人員的影響，需要對(duì)于拆除的部分灑水、降塵。施工的過(guò)程當(dāng)中，需要對(duì)于混凝土、鋼板等等進(jìn)行打磨。3、然后確定好門(mén)框門(mén)洞的尺寸，要在墻面上做出記號(hào)，再驗(yàn)證設(shè)計(jì)好的記號(hào)，彈線(xiàn)，再根據(jù)彈好的線(xiàn)通過(guò)工具打通，最后就能夠?qū)㈤T(mén)洞設(shè)置成功。
承重墻上可以打孔嗎打多大
在房屋結(jié)構(gòu)當(dāng)中，承重墻是主要承載重量的結(jié)構(gòu)框架，在裝修的過(guò)程當(dāng)中，是可以進(jìn)行鉆孔施工的，但鉆孔的位置、鉆孔的大小、鉆孔的個(gè)數(shù)都是有規(guī)范的。開(kāi)孔10公分左右對(duì)結(jié)構(gòu)安全不會(huì)有什么太大影響，但國(guó)家建筑裝飾施工規(guī)范要求是不允許的，打孔的過(guò)程中可能會(huì)對(duì)受力鋼筋造成損傷，同時(shí)可能會(huì)對(duì)樓體外側(cè)的保溫層及防水層造成破壞。建議煙機(jī)還是采用開(kāi)發(fā)商原有設(shè)計(jì)的通風(fēng)管道進(jìn)行排煙處理。如果要進(jìn)行開(kāi)孔處理，建議*是征得物業(yè)同意后操作。
