Construction basket project whether need expert proof?
Step: prefabricated beam plate with I type basket size, with the size of your "Guanghe Guangshi (bridge) - V" or "the reference bridge set (2005) 4004- 1"; continuous beam hanging basket plate plate plate adopts the step step step type I and type II, type III and IV size see, "your drawings with dimensions (Hiroka Hirose bridge) -X (12~20) - Part VIII" and "expensive Guanghe Guangshi (bridge) and -X (21~33) second - VIII section", all of the prefabricated plate of Zhaoqing beam field, using C20 concrete prefabricated steel processing in 1# mixing station.
The installation must be checked before the basket basket shaped bolt, embedded parts such as U fixed angle bracket for connecting end of the rail vertical bar and U bar shaped buried, the plane and vertical position. To determine the installation position in the basket of steel embedded parts installation accuracy.
Continuous beam is divided into A type, B type, C type, the specific size for your "Guanghe Guangshi (bridge) -X one or two" section viii. Support production after completion of steel anti-corrosion treatment, namely special Hongdan oil once, grey lead oil two. The stent should be spread with care, no drag, prevent coating surface damage, coating damage, affect the anti-corrosion effect; such as in the transportation process because of friction appear paint, after the completion of the stent installation, two times filling spray treatment
Each of the 8 baskets is supported by a simple beam, and a B type bracket is used at both ends of the basket to prevent lateral movement of the walking board. The middle two supports are A type. First, N1, N2 and N3 are welded together into A type brackets. N1 and N3 are welded into B type brackets, and then welding pads and diaphragms are respectively welded on type A and B type brackets. Support production is completed, according to the "standard" railway bridge protection coating on steel, anti-corrosion treatment, namely special Hongdan oil once, grey lead oil two
