由于(yu)(yu)很多(duo)二(er)次(ci)裝修的(de)(de)住宅是(shi)(shi)(shi)老房(fang)，’在(zai)(zai)結構上(shang)有些不合(he)(he)人意，有時需要(yao)拆(chai)掉(diao)一(yi)(yi)些墻(qiang)(qiang)將空(kong)間重(zhong)(zhong)(zhong)(zhong)新(xin)整合(he)(he)，但因為(wei)老房(fang)的(de)(de)墻(qiang)(qiang)面大部分都是(shi)(shi)(shi)承(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)墻(qiang)(qiang)，不能隨(sui)便拆(chai)除，否(fou)則會改(gai)變房(fang)屋受力結構。也不可隨(sui)意在(zai)(zai)承(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)墻(qiang)(qiang)上(shang)打(da)洞(dong)或(huo)開門，否(fou)則將帶來(lai)(lai)嚴重(zhong)(zhong)(zhong)(zhong)的(de)(de)隱患。辨別(bie)承(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)墻(qiang)(qiang)的(de)(de)方(fang)法(fa)有很多(duo)，最(zui)(zui)準確的(de)(de)是(shi)(shi)(shi)按照原有圖紙來(lai)(lai)辨別(bie)，或(huo)者是(shi)(shi)(shi)找專業人士(shi)對(dui)房(fang)屋的(de)(de)結構進行重(zhong)(zhong)(zhong)(zhong)新(xin)梳理。一(yi)(yi)般(ban)來(lai)(lai)說，可以(yi)(yi)根據(ju)墻(qiang)(qiang)體的(de)(de)厚度(du)來(lai)(lai)判斷(duan)是(shi)(shi)(shi)否(fou)是(shi)(shi)(shi)承(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)墻(qiang)(qiang)。對(dui)于(yu)(yu)房(fang)屋中厚度(du)在(zai)(zai)24cm以(yi)(yi)上(shang)的(de)(de)墻(qiang)(qiang)最(zui)(zui)好不要(yao)拆(chai)，這(zhe)類(lei)墻(qiang)(qiang)大多(duo)都是(shi)(shi)(shi)承(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)或(huo)者配重(zhong)(zhong)(zhong)(zhong)墻(qiang)(qiang)。此外。承(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)墻(qiang)(qiang)一(yi)(yi)般(ban)較密實(shi)，用手(shou)敲擊(ji)(ji)悶實(shi)而(er)無響聲，而(er)敲擊(ji)(ji)起來(lai)(lai)有“空(kong)聲兒”的(de)(de)墻(qiang)(qiang)面，大多(duo)屬于(yu)(yu)非承(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)墻(qiang)(qiang)，可以(yi)(yi)拆(chai)改(gai)。一(yi)(yi)般(ban)在(zai)(zai)磚混結構的(de)(de)建筑物中，凡是(shi)(shi)(shi)預制墻(qiang)(qiang)板一(yi)(yi)律不能拆(chai)除或(huo)開門開窗(chuang)(chuang)。另外。有人在(zai)(zai)承(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)墻(qiang)(qiang)上(shang)開門開窗(chuang)(chuang)，這(zhe)會破壞墻(qiang)(qiang)體的(de)(de)承(cheng)(cheng)重(zhong)(zhong)(zhong)(zhong)，是(shi)(shi)(shi)不允許的(de)(de)。
