Cable tray span and support issues
Thread Content
The factory building is made of steel structure, without walls; the span between the columns is either 7.5 meters or 6 meters. How can cable trays be supported in such a building? Will a support with a span of 7.5m work?
The spacing between the hanger frames for sliding doors should be two meters apart. If there is not enough space above, it is possible to consider welding triangular support arms using square steel or I-beams with dimensions of at least 100*100; these steel members can then be used to connect the support arms across each other, and the cable trays can be installed on these welded profiles
The span of the columns is quite large, reaching 7.5 meters. Will it be sufficient to use only supports on the columns?
If the span of the columns reaches 7.5m, it is not sufficient to rely on supports placed only on the columns, as the strength required will not be met; in such cases, the method used for the third floor must be adopted
So, is it okay to use supports with a span of 3.5m?
We need to discuss what size the cable tray should be and how much cable can be installed A structure was constructed with dimensions of 400*200, a cable span of 7 meters; the triangular support members were made of 20# I-beams. For the horizontal sections, a truss structure was used, similar to those found in open-air conduit systems. The main structural members were 12# channel steel, the secondary members were 8# channel steel, and the triangular bracing members were made of 50# angle steel. Ask a structural engineer for specific guidance; these issues are all easy to resolve
It depends on the specifications of your cable and the capacity of the cable tray; for detailed requirements, refer to the standard GB50127-2007
This must be carried out in strict accordance with standard specifications; we have provided users with cable trays, and the construction teams are extremely meticulous when it comes to installation
When purchasing, choose bridge trays with a large span; as long as their quality is satisfactory. During installation, provide appropriate support on site (if vertical supports aren’t suitable, inclined supports can be used to change the angle).
