電纜橋架及附件應選用通過防腐處理的定型產(chǎn)品，其類型、標準應適宜規(guī)劃要求。橋架支吊架可用圓鋼、扁鋼、角鋼等制造，大型橋架也能夠用槽鋼締造。支吊架締造結(jié)束后應進行除銹，刷防銹漆。

Cable trays and accessories should be selected as standardized products that have undergone anti-corrosion treatment, and their types and standards should be suitable for planning requirements. Bridge supports and hangers can be made of round steel, flat steel, angle steel, etc., and large bridge frames can also be made of channel steel. After the construction of the support and hanger is completed, rust should be removed and anti rust paint should be applied.

支、吊架締造設(shè)備：橋架筆直設(shè)備時，先把上面的一個支架固定好，再用線錘在中心線處吊線，下面的支架即可按吊線均勻進行固定。橋架水安定裝時，能夠先把兩頭的固定好，然后以兩頭的支架為基準用拉線法均勻設(shè)置支架。橋架水安定裝時，在首段、中心、結(jié)束等恰當方位增加防晃支架。支架與預埋鐵件焊接固定，焊縫豐滿。膨脹螺栓固準時，選用螺栓適配，毗鄰緊固。

Support and hanger creation equipment: When the bridge is straight, first fix the upper bracket, and then use a plumb bob to hang the line at the centerline. The lower bracket can be evenly fixed according to the hanging line. When installing the water stability of the bridge, the two ends can be fixed first, and then the brackets on both ends can be uniformly set using the wire drawing method as the reference. When installing the water stability of the bridge, add anti shake brackets in appropriate positions such as the first section, center, and end. The bracket is welded and fixed with embedded iron components, and the weld seam is full. When fixing the expansion bolt, select the appropriate bolt and tighten it adjacent to it.

當規(guī)劃無要求時，電纜橋架水安定裝的支架距離為每隔1.5~3米設(shè)置一個。筆直設(shè)備的支架距離不大于2米。橋架敷設(shè)設(shè)備：非鍍鋅電纜橋架間銜接板的兩頭跨接銅芯接地線或編織帶，接地線小截面積不小于4平方毫米，跨接接地線必需跨接在專用接地螺栓上。鍍鋅電纜橋架銜接板的兩頭可不跨接接地線，但銜接板的兩頭部少于2個防松螺帽或防松墊圈的銜接固定螺栓。

When there are no requirements in the planning, the support distance for cable tray water stabilization installation should be set every 1.5-3 meters. The distance between the brackets of straight equipment shall not exceed 2 meters. Bridge laying equipment: The two ends of the connecting plate between non galvanized cable trays should be crossed with copper core grounding wire or woven tape, and the small cross-sectional area of the grounding wire should not be less than 4 square millimeters. The cross grounding wire must be crossed on a dedicated grounding bolt. The two ends of the galvanized cable tray connection plate may not be connected to the grounding wire, but the two ends of the connection plate have less than two locking nuts or locking washers for the connection fixing bolts.

金屬電纜橋架及其支架全長不少于處于接地或接零干線相銜接。敷設(shè)在豎井內(nèi)和穿越不同防火分區(qū)的橋架依照規(guī)劃要求方位必須有防火隔堵方法。直線段鋼制電纜橋架長度超越30米、鋁合金或玻璃鋼制電纜橋架長度超越15木設(shè)有彈性節(jié)。電纜橋架跨建筑物變形縫處設(shè)置補償設(shè)備

The total length of the metal cable tray and its bracket shall not be less than the connection between the grounding or neutral main line. Cable trays laid in vertical shafts and passing through different fire compartments must have fire blocking methods in accordance with the planning requirements. Steel cable trays with straight sections exceeding 30 meters in length, and aluminum alloy or fiberglass cable trays exceeding 15 meters in length are equipped with elastic joints. Install compensation equipment at the deformation joint of the cable tray crossing the building
