With the development of society, Shandong cable tray is widely used in various fields. Cable tray plays a supporting role in the process of wire and cable installation. It can not only regulate the installation of wire and cable, but also has a certain protective effect on them. Therefore, Shandong cable tray needs to have a certain bearing capacity. If there is no good bearing capacity, it will have a certain impact on the construction. Next, Xiaobian will take you to understand what factors will affect the bearing capacity of Shandong bridge cable.
Shandong cable bridge
The cable bridge frame is made of sheet steel, which has limited bearing capacity. It will be deformed due to bridge overload, which will not only affect the beauty of the bridge, but also affect the safe operation of the cable. Under normal conditions, the bearing capacity of the cable bridge frame is represented by the load characteristic curve of the cable bridge frame. It can be seen from the load curve that the bearing capacity is related to the specification and support distance of the bridge, corresponding to the same support distance, bending and bulge deformation. The side height is large and the bearing capacity is large. When the bearing capacity is the same, the bending deformation of cable bridge frame with the same specification and small support distance is smaller.
1. Dynamic load refers to the weight of construction and maintenance personnel during bridge installation and maintenance. For the light cable bridge frame, the dynamic load is not considered, that is, people are not allowed to stand on the bridge frame. If people need to be considered, the span should be reduced appropriately.
2. Static load refers to the type, number of cables laid in Shandong cable tray, and the weight / unit length of each cable outside diameter, which are listed and counted according to different routes of cable laying.
3. Additional load refers to the load formed by ice, snow, wind and electromagnetic force only outdoors. It is related to the natural weather conditions of the installation site and the nature of the charged body. The design shall be calculated according to various conditions.
Bridges can be erected on their own, and, of course, they can be laid on various buildings and pipe supports. They have many characteristics and advantages, because they can not only reflect the simple structure, beautiful appearance, but also show the characteristics of flexible configuration and convenient maintenance.
Shandong cable bridge
The above is a number of factors that affect the bearing capacity of cable tray in Shandong Province. I hope the above contents can help you. At present, cable bridge frame is usually divided into slot type, tray type, ladder type, net type and other structural types. In addition, no matter what type of cable bridge frame is made up of some parts, these parts are composed of bracket, support arm, installation accessories and other parts.
