电缆桥架的施工流程要注意什么?

电缆桥架及附件应选用通过防腐处理的定型产品,其类型、标准应适宜规划要求。桥架支吊架可用圆钢、扁钢、角钢等制造,大型桥架也能够用槽钢缔造。支吊架缔造结束后应进行除锈,刷防锈漆。

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、吊架缔造设备:桥架笔直设备时,先把上面的一个支架固定好,再用线锤在中心线处吊线,下面的支架即可按吊线均匀进行固定。桥架水安定装时,能够先把两头的固定好,然后以两头的支架为基准用拉线法均匀设置支架。桥架水安定装时,在首段、中心、结束等恰当方位增加防晃支架。支架与预埋铁件焊接固定,焊缝丰满。膨胀螺栓固准时,选用螺栓适配,毗邻紧固。

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.

当规划无要求时,电缆桥架水安定装的支架距离为每隔1.5~3米设置一个。笔直设备的支架距离不大于2米。桥架敷设设备:非镀锌电缆桥架间衔接板的两头跨接铜芯接地线或编织带,接地线小截面积不小于4平方毫米,跨接接地线必需跨接在专用接地螺栓上。镀锌电缆桥架衔接板的两头可不跨接接地线,但衔接板的两头部少于2个防松螺帽或防松垫圈的衔接固定螺栓。

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.

金属电缆桥架及其支架全长不少于处于接地或接零干线相衔接。敷设在竖井内和穿越不同防火分区的桥架依照规划要求方位必须有防火隔堵方法。直线段钢制电缆桥架长度超越30米、铝合金或玻璃钢制电缆桥架长度超越15木设有弹性节。电缆桥架跨建筑物变形缝处设置补偿设备

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
