style="text-indent:25px">預(yù)應(yīng)力鋼絞線為什么不可以不割而不采用連接器。1.超長(zhǎng)孔道必然帶來(lái)很大的孔道摩擦，過(guò)大的摩擦力必然影響預(yù)應(yīng)力加載效果。 2.構(gòu)件長(zhǎng)度如果超出一定范圍，溫度變形等將無(wú)法控制。 3.有的結(jié)構(gòu)要求必須連續(xù)，預(yù)應(yīng)力筋也要保證和前邊結(jié)構(gòu)相同的布置形式，所以就必須采用連接器將預(yù)應(yīng)力筋連接起來(lái)。 4.還有的結(jié)構(gòu)因?yàn)橐侄问┕?，不可能一次連續(xù)施工完畢，此時(shí)也要分段張拉錨固，連接器也就必不可少了。 5.對(duì)于先張法預(yù)制臺(tái)座，同一臺(tái)座可能制作很多種預(yù)應(yīng)力構(gòu)件，此時(shí)采用單孔連接器可以節(jié)省大量的預(yù)應(yīng)力筋。</p><p
