电缆桥架支吊架怎么安装?

电缆桥架设置时需要固定,不能悬空。要寻找固定点支撑和固定。电缆桥架和这个固定点之间的距离叫做电缆桥架固定点间距。
The cable tray shall be fixed and shall not be suspended. Look for fixed points to support and fix. The distance between the cable tray and this fixed point is called the cable tray fixed point spacing.

(1)支架和吊架所用钢材应平整,无明显扭曲。出料后的长度偏差在3mm范围内,切口无卷曲、毛刺。
(1) The steel used for supports and hangers shall be flat without obvious distortion. The length deviation after discharging shall be within 3mm, and the notch shall be free of curl and burr.
(2)钢托架和吊架焊接牢固,无显着变形,焊前厚度超过4mm的托架,铁材开坡口,焊接均匀平整,焊接长度应符合要求,不得产生龟裂、蚀端、气孔、凹陷、焊接泄漏等缺陷。
(2) The steel bracket and hanger shall be welded firmly without significant deformation. For the bracket with a thickness of more than 4mm before welding, the iron material shall be beveled, the welding shall be uniform and flat, the welding length shall meet the requirements, and there shall be no cracks, corroded ends, pores, depressions, welding leakage and other defects.
(3)支架与吊架应安装牢固,保证横平竖直,在有坡度的建筑物上安装支架与吊架应与建筑物的坡度、角度一致。
(3) The supports and hangers shall be firmly installed to ensure horizontal and vertical. The installation of supports and hangers on sloping buildings shall be consistent with the slope and angle of the buildings.
电缆支架的层间允许较小距离,当设计无规定时,但层间净距不应小于两倍电缆外径加10mm,35kV及以上高压电缆不应小于2倍电缆外径加50mm。
Small distance is allowed between layers of cable support. When there is no provision in the design, but the clear distance between layers shall not be less than twice the cable outer diameter plus 10mm, and for 35kV and above high-voltage cables, it shall not be less than twice the cable outer diameter plus 50mm.
(4)支架与吊架的规格一般不应小于扁钢30mm X 3mm,角钢25mmX 25mmX 3mm。
(4) Generally, the specifications of supports and hangers shall not be less than 30mm x 3mm for flat steel and 25mm x 25mm x 3mm for angle steel.
电缆支架应安装牢固,横平竖直;托架、支吊架的固定方式应按设计要求进行。各支架的同层横挡应在同一水平面上,其高低偏差不应大于5mm。托架、支吊架沿桥架走向左右的偏差不应大于10mm,在有坡度的电缆沟内或建筑物上安装的电缆支架,应有与电缆沟或建筑物相同的坡度。电缆支架上层及下层至沟顶、楼板或沟底、地面的距离。
The cable support shall be installed firmly, horizontally and vertically; The fixing method of brackets, supports and hangers shall be carried out according to the design requirements. The cross stop of the same layer of each support shall be on the same horizontal plane, and its height deviation shall not be greater than 5mm. The left-right deviation of brackets, supports and hangers along the bridge direction shall not be greater than 10mm. The cable supports installed in the sloping cable trench or buildings shall have the same slope as the cable trench or buildings. Distance from upper and lower layers of cable support to trench top, floor or trench bottom and ground.
(5)严禁用电气焊切割钢结构或轻钢龙骨任何部位。
(5) It is forbidden to cut any part of steel structure or light steel keel by electric welding.
(6)吊设备具应采用定型产品,并应有各自独立的吊装卡具或支撑系统。
(6) The lifting equipment shall adopt finalized products and shall have their own independent lifting fixtures or support systems.
(7)固定支点间距一般不应大于1。 5-2m。在进出接线盒、箱、柜、转角、转弯和变形缝两端及丁字接头的三端500mm以内应设固定支持点。
(7) The distance between fixed fulcrum shall not be greater than 1. 5-2m。 Fixed support points shall be set within 500mm from both ends of inlet and outlet junction boxes, boxes, cabinets, corners, turns and deformation joints and three ends of T-joints.
(8)严禁用木砖固定支架与吊架。
(8) It is forbidden to fix the support and hanger with wood bricks.
