            有哪些因素会影响桥架电缆的承载能力?

            随着社会的发展,山东电缆桥架广泛应用于各个领域,桥架是在电线电缆安装的过程中对电线电缆起到承托作用的,它不仅可以规范电线电缆的安装,而且对它们有一定的保护作用。因此,山东电缆桥架需要有一定的承载能力。如果没有良好的承载力,就会对施工产生一定的影响。接下来,小编就带你了解一下有哪些因素会影响山东桥架电缆的承载能力。
            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 protect them. Therefore, Shandong cable bridge 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 know what factors will affect the carrying capacity of Shandong cable tray.
            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,还会影响电缆的安全运行。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 frame of cable bridge is made of sheet steel and has limited bearing capacity. It will be deformed due to the overload of the bridge, which will not only affect the beauty of the bridge, but also affect the safe operation of the cable. The load-carrying capacity of the cable bridge frame under normal conditions is represented by the load-carrying capacity 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 and bending and bulging deformation. The side height is high and the bearing capacity is large. When the bearing capacity is the same, the bending deformation of the 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 in the process of bridge installation and maintenance. For the light cable bridge frame, the dynamic load is generally not considered, that is, people are not allowed to stand on the bridge frame. If it is necessary to consider standing people, the span should be appropriately reduced.
            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, outer diameter weight / unit length of cables laid in Shandong cable tray, which are listed and counted according to different routes of cables laid.
            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 meteorological conditions of the installation site and the nature of the charged body. The design should 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 built independently. Of course, in addition, 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 and beautiful appearance, but also show the characteristics of flexible configuration and convenient maintenance.
