水(shui)(shui)(shui)(shui)工(gong)建筑常用(yong)的(de)防水(shui)(shui)(shui)(shui)材(cai)料(liao)包含了(le)止水(shui)(shui)(shui)(shui)銅(tong)(tong)(tong)帶、橡膠止水(shui)(shui)(shui)(shui)等，止水(shui)(shui)(shui)(shui)銅(tong)(tong)(tong)帶在使用(yong)過(guo)程(cheng)中均(jun)會根據(ju)設計成(cheng)型(xing)。由于(yu)止水(shui)(shui)(shui)(shui)銅(tong)(tong)(tong)帶卷材(cai)長(chang)(chang)(chang)度過(guo)長(chang)(chang)(chang)，在成(cheng)型(xing)過(guo)程(cheng)中以(yi)及安裝(zhuang)施工(gong)過(guo)程(cheng)中操作不便(bian)，因此(ci)會選(xuan)擇(ze)裁剪成(cheng)一定長(chang)(chang)(chang)度再進行成(cheng)型(xing)。GBT 2059-2017對止水(shui)(shui)(shui)(shui)銅(tong)(tong)(tong)帶成(cheng)型(xing)長(chang)(chang)(chang)度無明確要求(qiu)，因此(ci)可(ke)(ke)以(yi)根據(ju)情況選(xuan)擇(ze)合適長(chang)(chang)(chang)度。止水(shui)(shui)(shui)(shui)銅(tong)(tong)(tong)帶剪切過(guo)短，導致黑龍江止水(shui)(shui)(shui)(shui)銅(tong)(tong)(tong)片接頭增多(duo)，焊接、檢驗費時較多(duo)；剪切長(chang)(chang)(chang)度過(guo)長(chang)(chang)(chang)，不利于(yu)成(cheng)型(xing)和(he)安裝(zhuang)，因此(ci)目前銅(tong)(tong)(tong)止水(shui)(shui)(shui)(shui)廠家均(jun)采用(yong)2m~6m的(de)加工(gong)長(chang)(chang)(chang)度，且可(ke)(ke)有效(xiao)減(jian)少止水(shui)(shui)(shui)(shui)銅(tong)(tong)(tong)片接頭數量(liang)。
