Specification for requirements for construction technology of aluminum alloy cable tray

Release time:

2024-01-31

As we all know, the construction technology of aluminum alloy cable tray vendors must be carried out in accordance with the approved design specifications.

As we all know, the construction technology of aluminum alloy cable tray vendors must be carried out in accordance with the approved design specifications.
When it is necessary to modify the design, it shall be agreed by the original design unit.
Then we will introduce the requirements and specifications of the construction technology of aluminum alloy cable bridge.
I hope I can help you all!
1.The installation of aluminum alloy bridge shall be carried out in accordance with the installation instructions or relevant materials provided by the manufacturer.
2.Aluminum bridges shall not be used as pedestrian passageways, ladders or standing platforms, and their supporting frames shall not be used as lifting supports.
There must be safety measures for high-altitude work.
3.In the process of transportation, hoisting and construction, measures should be taken to prevent the damage of aluminum alloy bridge and its surface protective layer.
4.Do not wear hard-soled shoes to step on the bridge during construction to prevent tools from falling and damaging the bridge.
5.When the surface of trays and ladders is coated with insulation, the insulation at the drop point or electrical connection should be cleaned.
6.Aluminum alloy bridge, the surface spray or paint protective layer, after cutting the bridge, drilling, the exposed metal surface of the corresponding anti-corrosion coating or paint repair.
The surface treated by anodizing can not be repaired.
7.Spring washers should be installed on the connection fastening bolts in the vibration position and the electrical grounding position.
8.In the straight line section configuration of pallet and ladder frame, the expansion joint composed of telescopic connecting plate should be set at appropriate distance, and the larger allowable temperature difference should be determined according to the larger temperature difference in the engineering environment.
9.The fixing of the straight line section of the tray and ladder frame on the support and hanger should meet the following requirements:
(1)in the middle of the adjacent expansion joint, the tray, ladder frame and support frame are fixed together with fixed compression parts.
(2)the guide parts should be used to restrain the transverse position of the support on the remaining support, so that the support can stretch longitudinally from the fixed point along both sides.
(3)during installation, do not fasten the retractable connecting plate with the side connecting bolts of the pallet and the ladder rack to adapt to the longitudinal expansion of the tray and the ladder rack.
10.For the aluminum alloy cable tray vendors installed on the steel support and hanger or fixed by steel accessories, when the surface of the steel member is hot-dipped galvanized, it can be in direct contact with the aluminum bridge; if the surface is sprayed powder coating, it must be used.
PVC contacts it with the aluminum bridge.
11.When laying the cable, the pulley for pulling the cable at the corner should not be installed directly on the aluminum alloy bridge, but can be installed on the steel frame and other structures.
12.The fixing of the cable on the aluminum alloy bridge should conform to the design code of power engineering cable.
13.The cable is laid on the open bridge, and when the construction is completed, if there may be falling objects, the cable should be protected.
If there is a cover, cover it as early as possible.
