噴(pen)塑(su)橋(qiao)(qiao)架(jia)(jia)施工的注(zhu)意事項。布(bu)放(fang)(fang)在(zai)線(xian)(xian)(xian)(xian)槽的纜(lan)(lan)(lan)線(xian)(xian)(xian)(xian)可以不綁(bang)扎，槽內纜(lan)(lan)(lan)線(xian)(xian)(xian)(xian)應(ying)順直盡量不交叉。纜(lan)(lan)(lan)線(xian)(xian)(xian)(xian)不應(ying)溢出(chu)線(xian)(xian)(xian)(xian)槽，在(zai)纜(lan)(lan)(lan)線(xian)(xian)(xian)(xian)進出(chu)線(xian)(xian)(xian)(xian)槽部位轉彎處應(ying)綁(bang)扎固(gu)定。垂(chui)直線(xian)(xian)(xian)(xian)槽布(bu)放(fang)(fang)纜(lan)(lan)(lan)線(xian)(xian)(xian)(xian)應(ying)每間隔1.5米固(gu)定在(zai)纜(lan)(lan)(lan)線(xian)(xian)(xian)(xian)支(zhi)架(jia)(jia)上(shang)。在(zai)水平、垂(chui)直橋(qiao)(qiao)架(jia)(jia)和垂(chui)直線(xian)(xian)(xian)(xian)槽中敷設線(xian)(xian)(xian)(xian)時，應(ying)對纜(lan)(lan)(lan)線(xian)(xian)(xian)(xian)進行綁(bang)扎。4對線(xian)(xian)(xian)(xian)電(dian)纜(lan)(lan)(lan)以24根(gen)為束，橋(qiao)(qiao)架(jia)(jia)支(zhi)架(jia)(jia)，25對或以上(shang)主(zhu)干線(xian)(xian)(xian)(xian)電(dian)纜(lan)(lan)(lan)、光(guang)纜(lan)(lan)(lan)及其它型號(hao)電(dian)纜(lan)(lan)(lan)應(ying)根(gen)據纜(lan)(lan)(lan)線(xian)(xian)(xian)(xian)的類(lei)型、纜(lan)(lan)(lan)徑、纜(lan)(lan)(lan)線(xian)(xian)(xian)(xian)芯數分束綁(bang)扎。綁(bang)扎間距不宜大于1.5米，扣間距應(ying)均勻，松緊適度。

橋(qiao)(qiao)架(jia)(jia)的(de)選(xuan)擇：當(dang)鋼制直線段長度超過(guo)30m，鋁合金電(dian)(dian)(dian)纜(lan)橋(qiao)(qiao)架(jia)(jia)超過(guo)15m時．或(huo)當(dang)電(dian)(dian)(dian)纜(lan)橋(qiao)(qiao)架(jia)(jia)經過(guo)建筑伸(shen)縮(suo)(沉降)縫時應(ying)留有O-30mm補償余量．其連接宜采(cai)用伸(shen)縮(suo)連接板。橋(qiao)(qiao)架(jia)(jia)的(de)選(xuan)擇：在(zai)(zai)容易積聚粉塵的(de)場所，電(dian)(dian)(dian)纜(lan)橋(qiao)(qiao)架(jia)(jia)應(ying)選(xuan)用蓋板；在(zai)(zai)公共通(tong)道或(huo)室外跨(kua)越道路段．底層橋(qiao)(qiao)架(jia)(jia)上(shang)(shang)宜加墊板或(huo)使用無孔托盤。噴塑電(dian)(dian)(dian)纜(lan)橋(qiao)(qiao)架(jia)(jia)是將塑料(liao)粉末噴涂(tu)在(zai)(zai)電(dian)(dian)(dian)纜(lan)橋(qiao)(qiao)架(jia)(jia)上(shang)(shang)的(de)一種表面處(chu)理方法。

噴塑橋(qiao)(qiao)架(jia)(jia)(jia)優點：有些(xie)施工(gong)(gong)場合已經(jing)明(ming)確(que)提出必(bi)須使用靜電噴塑工(gong)(gong)藝(yi)處理；靜電噴粉(fen)噴涂過程中(zhong)不會出現(xian)噴漆工(gong)(gong)藝(yi)中(zhong)常(chang)見的流(liu)淌(tang)現(xian)象(xiang)。橋(qiao)(qiao)架(jia)(jia)(jia)的選擇：在(zai)容易(yi)積聚粉(fen)塵的場所，電纜(lan)(lan)橋(qiao)(qiao)架(jia)(jia)(jia)應選用蓋板；在(zai)公共通道(dao)或室外跨越(yue)道(dao)路段(duan)．底層橋(qiao)(qiao)架(jia)(jia)(jia)上宜加墊(dian)板或使用無孔托盤(pan)。電纜(lan)(lan)橋(qiao)(qiao)架(jia)(jia)(jia)分(fen)為(wei)槽式(shi)電纜(lan)(lan)橋(qiao)(qiao)架(jia)(jia)(jia)、托盤(pan)式(shi)電纜(lan)(lan)橋(qiao)(qiao)架(jia)(jia)(jia)和(he)梯級式(shi)電纜(lan)(lan)橋(qiao)(qiao)架(jia)(jia)(jia)、網格橋(qiao)(qiao)架(jia)(jia)(jia)等結構，由支架(jia)(jia)(jia)、托臂(bei)和(he)安裝附件等組成。
