Aluminum alloy is a very common material in the installation and construction of cable bridges, so we can see many bridges with very exquisite structures.
In fact, most of them are alloy cable tray made of aluminum alloy.
The reason why we choose aluminum alloy bridge is that aluminum alloy bridge has high strength and good corrosion resistance, and this material is also the first choice.
Matters needing attention in installation of aluminum alloy bridge
1.Before the construction of aluminum alloy bridge, it is necessary to formulate a perfect installation plan, fully consider some situations that may occur in the installation process, and formulate an emergency plan.
Plan the progress and construction of the installation project in strict accordance with the implementation plan.
Shall be carried out in accordance with the approved design.
2.The installation of aluminum alloy bridge shall be carried out in accordance with the installation and operation instructions or relevant materials provided by the manufacturer.
When the design needs to be modified, it shall be approved by the original design unit.
3.In the process of transportation, hoisting and construction, the surface of aluminum alloy bridge should be protected to prevent damage to alloy cable tray and its installation performance.
4.Aluminum alloy bridges shall not be used as pedestrian passageways, ladders or standing platforms, and their supports and hangers shall not be used as supports for lifting heavy objects.
These behaviors will lead to bridge deformation and affect the normal installation of the bridge.
5.When there is an insulating coating on the surface of the tray and ladder, the insulating layer at the contact site or electrical connection should be removed.
6.For aluminum alloy bridge with spray or paint protective layer, the exposed metal surface should be repainted after cutting and drilling holes in the bridge.
7.Spring washers should be installed on the connection and fastening bolts of vibration places and electrical grounding parts.
8.For the straight line section configuration of stainless steel alloy cable tray and ladder, the expansion joint composed of expansion connecting plate should be set at appropriate intervals, and the allowable to large distance value should be determined according to the engineering environment * large temperature difference.
9.The aluminum alloy bridge installed on the steel hanger or fixed with steel accessories can be in direct contact with the aluminum alloy bridge when the steel surface is hot-dipped galvanized; when its surface is coated with powder coating, PVC should be used to isolate the contact with the aluminum alloy bridge.
10.When laying the cable, the pulley used for towing the cable at the turn should not be directly fixed on the aluminum alloy bridge, but can be fixed on the steel frame and other structures.
The fixing of cables on aluminum alloy bridges should comply with the provisions of the Code for Design of Electric Power Engineering cables.
