针对铝合金桥架施工质量可以怎么提升？您知道有哪些需要注意的事项吗？为了更好的使用桥架进行工作，那么您就要对此方面有了解，下面济南电缆桥架厂家为您讲解。

How can the construction quality of aluminum alloy bridge be improved? Do you know what needs attention? In order to better use the cable tray for work, you should understand this aspect. Now, Jinan cable tray manufacturer will explain it to you.

铝合金桥架内电缆敷设整齐、顺直，无绞拧：

The cables in the aluminum alloy cable tray shall be laid neatly and straightly without twisting:

铝合金桥架中电缆有中间接头：

The cables in the aluminum alloy bridge have intermediate joints:

铝合金桥架内电缆敷设混乱、无绑扎，支架螺杆过长，防火封堵不符合要求：

The cables in the aluminum alloy cable tray are laid in disorder without binding, the support screw is too long, and the fireproof sealing does not meet the requirements:

铝合金桥架接地不符合要求，扁钢未固定：

The grounding of aluminum alloy bridge does not meet the requirements, and the flat steel is not fixed:

导线裸敷在梯架内，线缆堆集没有绑扎或绑扎不符合要求：

The conductor is laid bare in the ladder, and the cable stacking is not bound or the binding does not meet the requirements:

铝合金桥架跨越变形缝没有补偿装置，连接片螺栓不全，接地跨接未连接：

There is no compensation device for aluminum alloy bridge crossing deformation joint, the bolts of connecting piece are incomplete, and the grounding jumper is not connected:

直线段钢制铝合金桥架长度超过30m、铝合金或玻璃钢制铝合金桥架长度超过15m设有伸缩节；铝合金桥架跨越建筑物变形缝处设置补偿装置。

Expansion joints shall be set for steel aluminum alloy bridge with length of more than 30m and aluminum alloy or glass fiber reinforced plastic aluminum alloy bridge with length of more than 15m in straight section; Compensation device shall be set at the deformation joint of the aluminum alloy bridge crossing the building.

钢制铝合金桥架与镀锌铝合金桥架混接，且没有连接片，底部开孔用螺栓连接，没有跨接线：

The steel aluminum alloy bridge is mixed with the galvanized aluminum alloy bridge, and there is no connecting piece. The bottom opening is connected with bolts, and there is no jumper wire:

铝合金桥架末端没有端盖封堵，金属软管直接伸入铝合金桥架，软管与钢管混接没有专用接头。电线裸敷在铝合金桥架内，桥接内线缆无绑扎。铝合金桥架内螺栓未切除，易损伤电缆：

The end of the aluminum alloy cable tray is not blocked by the end cap, the metal hose extends directly into the aluminum alloy cable tray, and the hose is mixed with the steel pipe without a special joint. The wires are laid in the aluminum alloy cable tray without binding. The bolts in the aluminum alloy cable tray are not removed, and the cables are easy to be damaged:

电缆预留过短导致斜拉进箱内，没有穿管或铝合金桥架保护：

The cable reservation is too short, which causes the cable to be pulled into the box obliquely, and there is no protection through the pipe or aluminum alloy bridge:

铝合金桥架内电缆绑扎凌乱，部分电缆没有走铝合金桥架进箱子：

The cables in the aluminum alloy bridge are bound in disorder, and some cables are not brought into the box through the aluminum alloy bridge:

电缆从梯架内直接垂入箱子，没有穿铝合金桥架或导管保护：

The cable is directly plumbed into the box from the ladder, without aluminum alloy bridge or conduit protection:

铝合金桥架穿楼板处没有防火封堵措施，电缆敷设于梯架之外，且没有整理绑扎：

There is no fire blocking measures at the place where the aluminum alloy bridge passes through the floor, and the cable is laid outside the ladder without arrangement and binding:

规范要求：敷设在竖井内和穿越不同防火区的铝合金桥架，按设计要求位置，有防火隔堵措施。

Specification requirements: The aluminum alloy cable tray laid in the shaft and passing through different fire zones shall be provided with fire separation measures according to the design requirements.

铝合金桥架穿楼板处防火封堵不符合要求，有电线裸露：铝合金桥架穿楼板时没有防火封堵，电缆直接埋入混凝土内：铝合金桥架内电缆采用电线绑扎，有裸线敷设于梯架内！等等，您有需求可以随时来我们这里http://www.sddlqj.cn咨询！

The fireproof sealing at the place where the aluminum alloy bridge passes through the floor does not meet the requirements, and there are exposed wires: the aluminum alloy bridge passes through the floor without fireproof sealing, and the cables are directly buried in the concrete: the cables in the aluminum alloy bridge are bound with wires, and there are bare wires laid in the ladder!
