如果大家買的是二手房，那就需要拆掉以前的瓷磚和吊頂,進行混凝土拆除破碎。瓷磚拆除時要注意把水泥墊層一起拆除，切不可為了省錢只拆瓷磚，否則你的地面會高出許多。拆有地暖的地磚時一定要注意保護地暖管道，防止把地暖管道砸破。衛生間和廚房的地磚拆除時(shi)一(yi)(yi)定(ding)(ding)要(yao)(yao)注(zhu)意把下(xia)水(shui)口密封好(hao)，防(fang)(fang)止下(xia)水(shui)道被垃(la)圾(ji)堵住。 對(dui)(dui)于新房墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)壁(bi)(bi)的(de)(de)(de)(de)拆(chai)除。其實我(wo)本人并不(bu)是(shi)(shi)(shi)特(te)(te)別贊成對(dui)(dui)房間(jian)墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)壁(bi)(bi)的(de)(de)(de)(de)拆(chai)除，因(yin)為承(cheng)重(zhong)(zhong)(zhong)墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)，配重(zhong)(zhong)(zhong)墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)，頂(ding)梁(liang)(liang)都(dou)不(bu)可(ke)動，就(jiu)(jiu)算是(shi)(shi)(shi)非承(cheng)重(zhong)(zhong)(zhong)墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)的(de)(de)(de)(de)拆(chai)除也會影響(xiang)整棟樓的(de)(de)(de)(de)抗震(zhen)力（個(ge)人拆(chai)除沒(mei)有(you)太大(da)(da)(da)問(wen)題，但是(shi)(shi)(shi)如(ru)果(guo)(guo)整棟樓的(de)(de)(de)(de)居民(min)都(dou)隨(sui)意拆(chai)除非承(cheng)重(zhong)(zhong)(zhong)墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)，那就(jiu)(jiu)會大(da)(da)(da)大(da)(da)(da)降低樓房的(de)(de)(de)(de)抗震(zhen)力）。如(ru)果(guo)(guo)一(yi)(yi)定(ding)(ding)需要(yao)(yao)對(dui)(dui)墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)體進行(xing)拆(chai)除的(de)(de)(de)(de)話，最(zui)好(hao)能(neng)(neng)(neng)拿到房間(jian)的(de)(de)(de)(de)設計(ji)圖紙，這(zhe)(zhe)樣(yang)(yang)就(jiu)(jiu)能(neng)(neng)(neng)很好(hao)區(qu)分哪些墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)面是(shi)(shi)(shi)可(ke)以拆(chai)除的(de)(de)(de)(de)（這(zhe)(zhe)個(ge)去找物業）。如(ru)果(guo)(guo)拿不(bu)到圖紙的(de)(de)(de)(de)話，這(zhe)(zhe)樣(yang)(yang)就(jiu)(jiu)需要(yao)(yao)我(wo)們(men)人為地區(qu)分承(cheng)重(zhong)(zhong)(zhong)墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)和(he)非承(cheng)重(zhong)(zhong)(zhong)墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)了。首先我(wo)們(men)先來認識一(yi)(yi)下(xia)哪些是(shi)(shi)(shi)承(cheng)重(zhong)(zhong)(zhong)墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)，在(zai)框架結構(gou)的(de)(de)(de)(de)建筑在(zai)大(da)(da)(da)梁(liang)(liang)下(xia)的(de)(de)(de)(de)墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)體是(shi)(shi)(shi)非承(cheng)重(zhong)(zhong)(zhong)墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)，磚混結構(gou)的(de)(de)(de)(de)建筑外墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)及開間(jian)的(de)(de)(de)(de)長方向一(yi)(yi)般(ban)是(shi)(shi)(shi)承(cheng)重(zhong)(zhong)(zhong)墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)，這(zhe)(zhe)是(shi)(shi)(shi)堅決不(bu)能(neng)(neng)(neng)動的(de)(de)(de)(de)。不(bu)能(neng)(neng)(neng)動的(de)(de)(de)(de)還(huan)有(you)配重(zhong)(zhong)(zhong)墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)，配重(zhong)(zhong)(zhong)墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)就(jiu)(jiu)是(shi)(shi)(shi)陽臺與房間(jian)之間(jian)會有(you)一(yi)(yi)門一(yi)(yi)窗，窗戶可(ke)以拆(chai)掉，但是(shi)(shi)(shi)墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)不(bu)可(ke)動。還(huan)有(you)就(jiu)(jiu)是(shi)(shi)(shi)頂(ding)梁(liang)(liang)和(he)鋼筋。衛生間(jian)和(he)廚房也盡量不(bu)要(yao)(yao)動，如(ru)果(guo)(guo)動了一(yi)(yi)定(ding)(ding)要(yao)(yao)再做(zuo)(zuo)一(yi)(yi)次(ci)防(fang)(fang)水(shui)，并做(zuo)(zuo)閉水(shui)試驗。 砌墻(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)(qiang)時(shi)如(ru)果(guo)(guo)沒(mei)有(you)特(te)(te)殊要(yao)(yao)求盡量采用輕質材(cai)料。
