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.
The cables in the aluminum alloy cable tray shall be laid neatly and straightly without twisting:
The cables in the aluminum alloy bridge have intermediate joints:
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:
The grounding of aluminum alloy bridge does not meet the requirements, and the flat steel is not fixed:
The conductor is laid bare in the ladder, and the cable stacking is not bound or the binding does not meet the requirements:
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:
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.
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:
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:
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:
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:
The cable is directly plumbed into the box from the ladder, without aluminum alloy bridge or conduit protection:
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:
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.
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!
