The cable tray frame is stamped from thin steel plates with limited bearing capacity. It will deform due to overloading of the bridge, which not only affects the aesthetics of the bridge, but also affects the safe operation of the cable. Under normal circumstances, the bearing capacity of the cable bridge frame is represented by the load characteristic curve of the cable bridge frame. From the load curve, it can be seen that the bearing capacity is related to the specifications and support distance of the bridge, corresponding to the same support distance and bending protrusion deformation. High side height and high bearing capacity. Under the same bearing capacity, the bending deformation of cable bridge frames with the same specifications and small support distances is relatively small.
1. Dynamic load refers to the weight of construction and maintenance personnel during bridge installation and maintenance. For lightweight cable trays, dynamic loads are generally not considered, meaning that no one is allowed to stand on the tray. If it is necessary to consider standing people, the span should be appropriately reduced.
2. Static load refers to the type and quantity of cables laid in cable trays in Shandong Province, and the outer diameter weight/unit length of each cable, listed and calculated according to different cable laying routes.
3. Additional loads refer to loads formed solely outdoors by ice, snow, wind, and electromagnetic forces. This is related to the natural meteorological conditions at the installation site and the properties of the charged body. The design should be calculated based on various conditions.
The bridge can be erected independently. Of course, in addition, they can also be laid on various buildings and pipeline supports. They have many characteristics and advantages, as they not only reflect the simple structure and beautiful appearance, but also demonstrate the characteristics of flexible configuration and convenient maintenance.
