桥架的敷设
桥架的所有断口、开孔实行冷加工，线槽、桥架切割后的尖锐边缘加以修整，以防电缆刮伤，同时应在切割面上涂上防腐漆。
All the cracks and openings of the bridge frame are cold-worked, and the sharp edges of the wire groove and the bridge frame after cutting are trimmed to prevent the cable from scratching. At the same time, anti-corrosion paint should be applied on the cutting surface.
桥架安装前，必须与各专业协调，避免与大口径消防管、喷淋管、给水管、排水管及空调、通风设备发生矛盾。
Before erecting the bridge frame, it must be coordinated with other specialties to avoid conflicts with large caliber fire fighting pipes, sprinkler pipes, water supply pipes, drainage pipes, air conditioning and ventilation equipment.
桥架与支架间采用螺栓固定，在转弯处需仔细校核尺寸。桥架与桥架之间用连接板连接，连接螺栓采用半圆头螺栓，半圆头在桥架内侧。桥架之间缝隙须达到设计要求，确保一个系统的桥架连成一体。
The bolts between the bridge and support are fixed, and the dimensions should be carefully checked at the turning point. The bridge frame is connected with the bridge frame by a connecting plate, and the connecting bolts are semi-circular head bolts, and the semi-circular head is inside the bridge frame. The gap between the bridge must meet the design requirements to ensure that the bridge of a system is integrated into one.
桥架安装要横平竖直、整齐美观、距离一致、连接牢固，同一水平面内水平度偏差不超过5mm/m，直线度偏差不超过10mm/m。
The erection of the bridge should be horizontal and vertical, neat and beautiful, the distance is consistent, and the connection is firm. The horizontal deviation in the same horizontal plane should not exceed 5m m/m, and the straightness deviation should not exceed 10m m/m.
电缆桥架的总平面布置应作到距离最短，经济合理，安全运行，并应满足施工安装、维修和敷设的要求。
The general layout of cable bridge should be the shortest distance, economical and reasonable, safe operation, and should meet the requirements of construction, installation, maintenance and laying.
桥架上部距离棚或其它障碍不应小于0.3m；
The upper canopy or other obstacles of the bridge should not be less than 0.3m;
电缆桥架水平敷设时，支撑跨距为2m，在伸缩节两侧应安装吊架。垂直安装的支架间距为2m。
When the cable bridge is laid horizontally, the support span is 2m, and hangers should be installed on both sides of the expansion joint. The vertical mounting bracket spacing is 2m.
桥架直线段每隔30m应予留伸缩缝20-30mm，在伸缩节两侧应安装吊架。
The bridge section should be provided with expansion joints 20-30mm every 30m, and hangers should be installed on both sides of the expansion joint.
