怎么檢查橋架的外觀是否符合規定？
對于電纜橋架這種產品來講，外觀十分的重要！因為這影響著橋架的防腐和壽命等問題！下面濟南電纜橋架的小編就給大家分享一下檢查橋架的外觀是否符合規定的一些標準，希望對大家有所幫助！
The appearance of cable bridge is very important for this kind of product. Because it affects the anti-corrosion and life of the bridge. The next edition of Jinan Cable Bridge Frame will share with you some criteria for checking whether the appearance of the bridge meets the requirements. I hope it will be helpful to you all!
表面防腐層材料應符合現行有關標準的規定。
Surface anticorrosive coatings should comply with the relevant national standards.
熱浸鍍鋅的托盤、橋架鍍層表面應均勻，無毛刺、過燒、掛灰、傷痕、局部未鍍鋅（直徑2mm以上）等缺陷，不得有影響安裝的鋅瘤。螺紋的鍍層應光滑，螺栓連接件應能擰入。
Hot-dip galvanized pallet and bridge plating should be uniform, without burrs, burning, hanging ash, scars, local non-galvanized (diameter more than 2 mm) defects, and no galvanoma affecting installation. The plating of the threads should be smooth and the bolted joints should be able to be screwed in.
電鍍鋅的鋅層表面應光滑均勻，致密。不得有起皮、氣泡、花斑、局部未鍍、劃傷等缺陷。

橋架螺栓孔徑，在螺桿直徑不大于M16時，可比螺桿直徑大2mm。
The diameter of bolt hole in bridge frame is 2 mm larger than that of bolt when the diameter of bolt is less than M16.
螺栓連接孔的孔距允許偏差:同一組內相鄰兩孔間距±0.7mm,同一組內任意兩孔間距±1mm;相鄰兩組的端孔間距±1.2mm。
The allowable deviation of the hole spacing of bolt connection holes: the spacing of adjacent two holes in the same group (+0.7 mm), the spacing of any two holes in the same group (+1 mm), and the spacing of end holes in adjacent two groups (+1.2 mm).
