来源:工(gong)程建设标准化(hua)


我(wo)(wo)国(guo)发布首部《建(jian)筑(zhu)外(wai)(wai)(wai)墙(qiang)(qiang)外(wai)(wai)(wai)保(bao)(bao)温(wen)系(xi)统(tong)修缮标准》。近(jin)几年,我(wo)(wo)国(guo)外(wai)(wai)(wai)保(bao)(bao)温(wen)工(gong)(gong)程质(zhi)(zhi)量(liang)(liang)事故频发,常见的(de)外(wai)(wai)(wai)饰面开裂,外(wai)(wai)(wai)保(bao)(bao)温(wen)脱(tuo)落(luo)的(de)问题,引起(qi)了人们广(guang)泛关注(zhu)。这(zhei)些(xie)外(wai)(wai)(wai)保(bao)(bao)温(wen)质(zhi)(zhi)量(liang)(liang)事故给栖身在(zai)屋子里(li)的(de)业主带来了许多困惑。业内人士都知道,既有建(jian)筑(zhu)外(wai)(wai)(wai)墙(qiang)(qiang)外(wai)(wai)(wai)保(bao)(bao)温(wen)系(xi)统(tong)数(shu)目(mu)庞大(da)。然(ran)(ran)而,因为材料、设计和施工(gong)(gong)等(deng)因素,一(yi)些(xie)建(jian)筑(zhu)外(wai)(wai)(wai)墙(qiang)(qiang)外(wai)(wai)(wai)保(bao)(bao)温(wen)系(xi)统(tong)存(cun)在(zai)空鼓、开裂、渗水和脱(tuo)落(luo)等(deng)质(zhi)(zhi)量(liang)(liang)缺陷和损伤。固然(ran)(ran)我(wo)(wo)国(guo)大(da)规模采(cai)用(yong)外(wai)(wai)(wai)墙(qiang)(qiang)外(wai)(wai)(wai)保(bao)(bao)温(wen)系(xi)统(tong)的(de)时间并不(bu)长(zhang),但在(zai)实际(ji)使用(yong)过程中依然(ran)(ran)浮现了种(zhong)种(zhong)质(zhi)(zhi)量(liang)(liang)题目(mu)。

外(wai)(wai)(wai)(wai)墙(qiang)外(wai)(wai)(wai)(wai)保(bao)温(wen)(wen)(wen)(wen)的(de)(de)质量(liang)问题不但会影响建(jian)(jian)筑(zhu)(zhu)(zhu)美(mei)观,还(hai)会造(zao)成(cheng)(cheng)饰面层渗水,对(dui)居民日常生活(huo)产生较大(da)的(de)(de)影响,同(tong)时外(wai)(wai)(wai)(wai)墙(qiang)局部区(qu)(qu)域形成(cheng)(cheng)“热桥(qiao)”,导致保(bao)温(wen)(wen)(wen)(wen)效果降低(di),饰面层空鼓、脱落等问题甚至会造(zao)成(cheng)(cheng)居民的(de)(de)安全隐患,对(dui)公(gong)共安全造(zao)成(cheng)(cheng)不小(xiao)的(de)(de)影响。故,该(gai)标(biao)准(zhun)的(de)(de)制定是为(wei)(wei)了(le)规范建(jian)(jian)筑(zhu)(zhu)(zhu)外(wai)(wai)(wai)(wai)墙(qiang)外(wai)(wai)(wai)(wai)保(bao)温(wen)(wen)(wen)(wen)系(xi)统的(de)(de)检测(ce)、评(ping)估和(he)修(xiu)缮(shan)行为(wei)(wei),为(wei)(wei)今(jin)后(hou)既有建(jian)(jian)筑(zhu)(zhu)(zhu)外(wai)(wai)(wai)(wai)墙(qiang)外(wai)(wai)(wai)(wai)保(bao)温(wen)(wen)(wen)(wen)系(xi)统的(de)(de)修(xiu)缮(shan)提供技术支撑。有了(le)这份标(biao)准(zhun),今(jin)后(hou)咱(zan)们的(de)(de)小(xiao)区(qu)(qu)再(zai)进行外(wai)(wai)(wai)(wai)墙(qiang)翻(fan)修(xiu)的(de)(de)话,就有标(biao)准(zhun)可(ke)以(yi)依据了(le)。该(gai)标(biao)准(zhun)制定的(de)(de)主要目的(de)(de)是为(wei)(wei)了(le)规范建(jian)(jian)筑(zhu)(zhu)(zhu)外(wai)(wai)(wai)(wai)墙(qiang)外(wai)(wai)(wai)(wai)保(bao)温(wen)(wen)(wen)(wen)系(xi)统修(xiu)缮(shan)工程(cheng),治(zhi)理建(jian)(jian)筑(zhu)(zhu)(zhu)外(wai)(wai)(wai)(wai)墙(qiang)外(wai)(wai)(wai)(wai)保(bao)温(wen)(wen)(wen)(wen)系(xi)统质量(liang)缺陷和(he)损(sun)伤,保(bao)证系(xi)统的(de)(de)安全性(xing)和(he)保(bao)温(wen)(wen)(wen)(wen)性(xing)。

因此,仅为满足美观(guan)要(yao)求而(er)进(jin)(jin)行的建(jian)筑(zhu)外(wai)(wai)(wai)墙(qiang)(qiang)装饰层面的修复不属(shu)于(yu)本标准的适用范围(wei)。建(jian)筑(zhu)外(wai)(wai)(wai)墙(qiang)(qiang)外(wai)(wai)(wai)保(bao)(bao)温(wen)(wen)(wen)(wen)系(xi)(xi)统(tong)(tong)(tong)的缺(que)陷(xian)(xian)类型、缺(que)陷(xian)(xian)部位、缺(que)陷(xian)(xian)成因各(ge)不相同,不同缺(que)陷(xian)(xian)对保(bao)(bao)温(wen)(wen)(wen)(wen)系(xi)(xi)统(tong)(tong)(tong)的危害性(xing)也有(you)所不同,但对于(yu)既有(you)外(wai)(wai)(wai)墙(qiang)(qiang)外(wai)(wai)(wai)保(bao)(bao)温(wen)(wen)(wen)(wen)系(xi)(xi)统(tong)(tong)(tong),一旦产生了缺(que)陷(xian)(xian),无论其(qi)大小(xiao),都应及(ji)时采取措施(shi)进(jin)(jin)行修补、修复,否则(ze),轻则(ze)影响保(bao)(bao)温(wen)(wen)(wen)(wen)系(xi)(xi)统(tong)(tong)(tong)的外(wai)(wai)(wai)观(guan)质(zhi)量(liang)(liang),重则(ze)影响系(xi)(xi)统(tong)(tong)(tong)的寿命、安全性(xing)。当建(jian)筑(zhu)外(wai)(wai)(wai)墙(qiang)(qiang)外(wai)(wai)(wai)保(bao)(bao)温(wen)(wen)(wen)(wen)系(xi)(xi)统(tong)(tong)(tong)局部区域产生裂缝,且根据预评估结果(guo),保(bao)(bao)温(wen)(wen)(wen)(wen)系(xi)(xi)统(tong)(tong)(tong)其(qi)它区域不存在质(zhi)量(liang)(liang)隐(yin)患时,只需要(yao)进(jin)(jin)行缺(que)陷(xian)(xian)部位的修复;当建(jian)筑(zhu)的整片(pian)墙(qiang)(qiang)体普遍存在缺(que)陷(xian)(xian)或(huo)质(zhi)量(liang)(liang)隐(yin)患时,需要(yao)将外(wai)(wai)(wai)墙(qiang)(qiang)外(wai)(wai)(wai)保(bao)(bao)温(wen)(wen)(wen)(wen)系(xi)(xi)统(tong)(tong)(tong)全部铲除,并重新(xin)铺设外(wai)(wai)(wai)墙(qiang)(qiang)外(wai)(wai)(wai)保(bao)(bao)温(wen)(wen)(wen)(wen)系(xi)(xi)统(tong)(tong)(tong)。
