鋼筋網在橋梁工程的運用

主(zhu)要運用(yong)(yong)于市(shi)政橋(qiao)(qiao)梁(liang)和公路橋(qiao)(qiao)梁(liang)的橋(qiao)(qiao)面(mian)(mian)鋪裝(zhuang)，舊橋(qiao)(qiao)面(mian)(mian)改造，橋(qiao)(qiao)墩(dun)防裂(lie)等。經過國內(nei)上(shang)千(qian)座橋(qiao)(qiao)梁(liang)運用(yong)(yong)工程質(zhi)量(liang)驗(yan)收標明(ming)，選(xuan)(xuan)用(yong)(yong)焊接網(wang)(wang)(wang)明(ming)顯提(ti)高(gao)橋(qiao)(qiao)面(mian)(mian)鋪裝(zhuang)層質(zhi)量(liang)，保護層厚(hou)度合格率達97%以(yi)上(shang)，橋(qiao)(qiao)面(mian)(mian)平(ping)整度提(ti)高(gao)，橋(qiao)(qiao)面(mian)(mian)簡直無裂(lie)縫，鋪裝(zhuang)速度提(ti)高(gao)50%以(yi)上(shang)，下降橋(qiao)(qiao)面(mian)(mian)鋪裝(zhuang)工程造價約10%。橋(qiao)(qiao)面(mian)(mian)鋪裝(zhuang)層的鋼筋(jin)網(wang)(wang)(wang)應(ying)(ying)運用(yong)(yong)焊接網(wang)(wang)(wang)或預(yu)制冷軋帶肋鋼筋(jin)網(wang)(wang)(wang)，不宜運用(yong)(yong)綁扎鋼筋(jin)網(wang)(wang)(wang)。橋(qiao)(qiao)面(mian)(mian)鋪裝(zhuang)用(yong)(yong)鋼筋(jin)網(wang)(wang)(wang)的直徑及(ji)距(ju)離應(ying)(ying)根據(ju)橋(qiao)(qiao)梁(liang)結構(gou)方式(shi)及(ji)荷載等級斷定。鋼筋(jin)網(wang)(wang)(wang)距(ju)離可選(xuan)(xuan)用(yong)(yong)100一200mm，其直徑宜選(xuan)(xuan)用(yong)(yong)6一l00mm。鋼筋(jin)網(wang)(wang)(wang)縱(zong)、橫向宜選(xuan)(xuan)用(yong)(yong)持(chi)平(ping)距(ju)離，焊接網(wang)(wang)(wang)距(ju)頂面(mian)(mian)的保護層厚(hou)度不該小(xiao)于20mm。
