隨著市場變化橋架已經(jīng)遍布市場橋架分類有很多。而且在我們的生活中各個地方都會用到這款產(chǎn)品?，F(xiàn)在就由濟南航豐電纜橋架廠家給大家詳細介紹一下電纜橋架技術(shù)有什么要求？

With the change of the market, the cable tray has spread all over the market. And it's used everywhere in our lives. Now by Jinan Hangfeng cable bridge manufacturers to give you a detailed introduction of cable bridge technology what requirements?

撓度不應(yīng)大于4mm

The deflection shall not be greater than 4mm

螺栓孔徑可比螺桿公稱直徑大于1.5mm（螺桿直徑不應(yīng)大于M16）時或2mm（螺桿直徑不小于M20）時螺栓孔精度不應(yīng)低于H14級

When the nominal diameter of the comparable screw is greater than 1.5mm (the screw diameter shall not be greater than M16) or 2mm (the screw diameter shall not be less than M20), the accuracy of the bolt hole shall not be lower than h14

螺栓連接孔的孔距允許偏差：同一組內(nèi)相鄰兩孔間≤±0.7mm；同一組內(nèi)任意兩孔間≤±1.0mm,相鄰兩組的端孔間≤±1.2mm。

Allowable deviation of bolt hole distance: between two adjacent holes in the same group ≤ ± 0.7mm； Between any two holes in the same group ≤ ± 1.0 mm, between end holes of two adjacent groups ≤ ± 1.2mm。

在水平彎曲，垂直方向彎曲、分支和電纜梯架縮小寬度時，須使用制造廠的標準直角彎節(jié)，分支接頭，偏心縮節(jié)，直線縮節(jié)。

For horizontal bending, vertical bending, branch and cable ladder narrowing, the manufacturer's standard right angle bending joint, branch joint, eccentric shrinkage joint and straight shrinkage joint shall be used.

防火漆要求平整、光滑、均勻、不起皮、無氣泡水皰。

Fireproof paint should be flat, smooth, uniform, no peeling, no bubble blister.

附件表面防腐處理與橋架主體結(jié)構(gòu)相一致，電纜橋架的連接片開孔數(shù)量及使用連接螺栓、平彈墊套數(shù)、規(guī)格應(yīng)滿足規(guī)范跨接連接相應(yīng)要求。橋架的蓋板材質(zhì)規(guī)格應(yīng)等同于電纜橋架。

The surface anti-corrosion treatment of the accessories is consistent with the main structure of the cable tray. The number of holes in the connecting piece of the cable tray and the number and specification of connecting bolts and flat elastic pad sets used shall meet the corresponding requirements of the standard bridging connection. The material specification of the cover plate of the cable tray shall be the same as that of the cable tray.

提供電纜橋架附件數(shù)量應(yīng)充足，并能滿足施工所需要求。電纜橋架的連接片及跨接銅編織帶均考慮5%的余量，螺栓栓帽、墊片考慮百分之10%的余量。

The number of cable tray accessories shall be sufficient to meet the construction requirements. 5% allowance shall be considered for connecting piece and bridging copper braided belt of cable tray, and 10% allowance shall be considered for bolt cap and gasket.

電纜橋架生產(chǎn)長度為2米一節(jié)，長度為2米時，偏差不應(yīng)大于2mm

The production length of cable tray is 2m. When the length is 2m, the deviation shall not be greater than 2mm
