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.

山东电缆桥架

Shandong cable bridge

电缆桥框架由薄钢板冲压而成，承载能力有限。它会因桥梁超载而变形，这不仅会影响桥梁的美观，还会影响电缆的运行。正常情况下，电缆桥框架的承载能力由电缆桥框架的荷载特性曲线表示。从荷载曲线可以看出，承载能力与桥梁的规格和支撑距离有关，对应于相同的支撑距离和弯曲、凸起变形。侧面高度大，承载力大。当承载能力相同时，相同规格、小支撑距离的电缆桥框架弯曲变形较小。

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.动荷载是指桥架安装和维护过程中，施工维修人员的重量。对于轻型电缆桥框架，一般不考虑动荷载，即不允许人们站在桥梁框架上。如果需要考虑站人，跨度应该适当减小。

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.静荷载是指敷设在山东电缆桥架内的电缆种类、根数、每根的外径重量/单位长度，按电缆敷设的不同路由分别列表统计。

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.附加载荷是指仅在室外由冰、雪、风和电磁力形成的载荷。它与安装现场的自然气象条件和带电体的性质有关。设计应根据各种条件进行计算。

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.

桥梁可以独立架设，当然，除此之外，它们还可以铺设在各种建筑物和管架支架上。它们有许多特点和优点，因为这不仅能体现出结构简单、外形美观，而且还能表现出配置灵活、维护方便等特点。

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.

以上介绍的就是一些影响山东电缆桥架承载力的因素，希望以上内容对大家有所帮助。目前电缆桥框架通常分为槽式、托盘式、梯式、网式和其他结构类型。此外，无论哪种类型的电缆桥框架是由一些部分组成，这些部分是由支架，支撑臂，安装配件和其他部分组成。

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.
