GRC構件在我國發展的很快，但是一些理論知識相(xiang)對來(lai)說(shuo)還是比較滯后，導(dao)致很多(duo)朋友想要(yao)購買以及(ji)加盟就(jiu)有很多(duo)的困惑(huo)，不了解(jie)grc構件在外裝飾工程(cheng)中(zhong)的應用，那么今天小編就(jiu)來(lai)給(gei)大(da)家講解(jie)下(xia)GRC構件在外裝飾工程(cheng)中(zhong)帶來(lai)的便利有以下(xia)幾點：

第一、避免影響建筑質量、而產生裂縫

　　相鄰GRC產(chan)品間安(an)(an)裝后產(chan)生裂(lie)(lie)縫(feng)這(zhe)種裂(lie)(lie)縫(feng)多(duo)(duo)出現在(zai)垂(chui)直及水(shui)平(ping)長度較(jiao)大的(de)GRC線(xian)條(tiao)(tiao)接頭(tou)間,造(zao)成線(xian)條(tiao)(tiao)分節明顯,嚴重(zhong)(zhong)影(ying)響外(wai)飾(shi)面(mian)(mian)效果。GRC產(chan)品線(xian)條(tiao)(tiao)在(zai)外(wai)裝飾(shi)中大多(duo)(duo)制(zhi)成1.5~3米/根(gen),并(bing)用(yong)多(duo)(duo)根(gen)連接安(an)(an)裝在(zai)一起來(lai)勾(gou)勒外(wai)墻面(mian)(mian)效果,由(you)于(yu)一方(fang)面(mian)(mian)其(qi)自重(zhong)(zhong)較(jiao)重(zhong)(zhong),安(an)(an)裝時受力不均,受其(qi)自重(zhong)(zhong)影(ying)響,相鄰接頭(tou)間產(chan)生裂(lie)(lie)縫(feng);另一方(fang)面(mian)(mian),線(xian)條(tiao)(tiao)在(zai)安(an)(an)裝時由(you)多(duo)(duo)根(gen)連接,接頭(tou)在(zai)施工中處理(li)多(duo)(duo)用(yong)1:2水(shui)泥沙漿(jiang)填縫(feng),其(qi)熱膨脹系(xi)數與GRC水(shui)泥制(zhi)品不同(tong)。造(zao)成裂(lie)(lie)縫(feng);再有GRC線(xian)條(tiao)(tiao)安(an)(an)裝時,尤其(qi)是水(shui)平(ping)方(fang)向線(xian)條(tiao)(tiao)未(wei)留伸縮縫(feng),當氣(qi)溫變化(hua)時在(zai)接頭(tou)被拉開(kai)或擠裂(lie)(lie),而產(chan)生裂(lie)(lie)紋。

　第二、避免安全隱患

　　避免(mian)GRC構(gou)件在(zai)預(yu)埋鋼(gang)骨(gu)架(jia)的(de)位置產生順鋼(gang)筋(jin)(jin)方向的(de)銹脹裂縫GRC構(gou)件中的(de)預(yu)埋骨(gu)架(jia)鋼(gang)筋(jin)(jin)和預(yu)埋件應采用鍍鋅(xin)鋼(gang)筋(jin)(jin)或不(bu)銹鋼(gang)條,或采用其他防銹處(chu)理,以避免(mian)銹脹裂縫的(de)產生,消除安全隱患。

　第三、建筑外觀不受影響

　　GRC線(xian)(xian)條(tiao)(tiao)的滲水(shui)及墻(qiang)(qiang)(qiang)面(mian)(mian)(mian)(mian)(mian)污(wu)染(ran)(ran)外(wai)(wai)墻(qiang)(qiang)(qiang)面(mian)(mian)(mian)(mian)(mian)GRC線(xian)(xian)條(tiao)(tiao)在安(an)(an)裝(zhuang)使用后,尤其是(shi)(shi)(shi)水(shui)平(ping)線(xian)(xian)條(tiao)(tiao)下邊(bian)遇雨天(tian)便滲出雨水(shui),線(xian)(xian)條(tiao)(tiao)上口(kou)的雨水(shui)也沿著(zhu)線(xian)(xian)條(tiao)(tiao)流向墻(qiang)(qiang)(qiang)面(mian)(mian)(mian)(mian)(mian),把(ba)線(xian)(xian)條(tiao)(tiao)上的積灰(hui)帶到(dao)外(wai)(wai)墻(qiang)(qiang)(qiang)面(mian)(mian)(mian)(mian)(mian)。在外(wai)(wai)墻(qiang)(qiang)(qiang)面(mian)(mian)(mian)(mian)(mian)形成(cheng)(cheng)條(tiao)(tiao)條(tiao)(tiao)污(wu)跡(ji)印,嚴重污(wu)染(ran)(ran)了墻(qiang)(qiang)(qiang)面(mian)(mian)(mian)(mian)(mian),影響了建筑物(wu)(wu)的外(wai)(wai)觀。形成(cheng)(cheng)這種病(bing)害的主要原(yuan)因(yin)一是(shi)(shi)(shi)因(yin)為(wei)線(xian)(xian)條(tiao)(tiao)在安(an)(an)裝(zhuang)時未將舊(jiu)建筑物(wu)(wu)安(an)(an)裝(zhuang)線(xian)(xian)條(tiao)(tiao)處墻(qiang)(qiang)(qiang)面(mian)(mian)(mian)(mian)(mian)粉刷(shua)層鑿除(chu)再(zai)粉刷(shua)或新建筑物(wu)(wu)是(shi)(shi)(shi)先粉刷(shua)后安(an)(an)裝(zhuang)線(xian)(xian)條(tiao)(tiao),再(zai)補縫(feng);二是(shi)(shi)(shi)因(yin)為(wei)水(shui)平(ping)線(xian)(xian)條(tiao)(tiao)或柱(zhu)的頂面(mian)(mian)(mian)(mian)(mian)蓋(gai)板口(kou)未找坡(po)、未做滴(di)水(shui)線(xian)(xian),導致雨水(shui)從(cong)線(xian)(xian)條(tiao)(tiao)上口(kou)進入線(xian)(xian)條(tiao)(tiao)內,從(cong)線(xian)(xian)條(tiao)(tiao)下口(kou)流出或沿線(xian)(xian)條(tiao)(tiao)流向外(wai)(wai)墻(qiang)(qiang)(qiang)面(mian)(mian)(mian)(mian)(mian),造成(cheng)(cheng)墻(qiang)(qiang)(qiang)面(mian)(mian)(mian)(mian)(mian)污(wu)染(ran)(ran)。

  第四 、達到施工要求

　　GRC線條(tiao)在(zai)外墻(qiang)(qiang)上(shang)安裝(zhuang)時,一(yi)般是(shi)根據生(sheng)產廠家提供(gong)的安裝(zhuang)圖,在(zai)外墻(qiang)(qiang)面上(shang)安裝(zhuang)8~10的普(pu)通膨脹螺(luo)栓(shuan),然后(hou)用中?準6鋼筋將(jiang)其與線條(tiao)上(shang)預埋鋼筋焊(han)接,或者(zhe)是(shi)直接用膨脹螺(luo)栓(shuan)將(jiang)裝(zhuang)飾凸塊、窗頂花固定在(zai)墻(qiang)(qiang)面上(shang)。上(shang)述安裝(zhuang)辦法,在(zai)施工中一(yi)般都采(cai)用點(dian)焊(han)的辦法,焊(han)縫長度達不到要(yao)(yao)求(qiu),膨脹螺(luo)栓(shuan)打人墻(qiang)(qiang)體后(hou),很容易打在(zai)磚縫里(li),不能起到作(zuo)用,達不到施工《規范(fan)》的要(yao)(yao)求(qiu),給GRC線條(tiao)的安裝(zhuang)帶(dai)來了隱(yin)患(huan)。
