有哪些因素會(huì )影響橋架電纜的承載能力？
隨著(zhù)社會(huì )的發(fā)展，山東電纜橋架廣泛應用于各個(gè)領(lǐng)域，橋架是在電線(xiàn)電纜安裝的過(guò)程中對電線(xiàn)電纜起到承托作用的，它不僅可以規范電線(xiàn)電纜的安裝，而且對它們有一定的保護作用。因此，山東電纜橋架需要有一定的承載能力。如果沒(méi)有良好的承載力，就會(huì )對施工產(chǎn)生一定的影響。接下來(lái)，小編就帶你了解一下有哪些因素會(huì )影響山東橋架電纜的承載能力。
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.
山東電纜橋架
Shandong cable bridge
電纜橋框架由薄鋼板沖壓而成，承載能力有限。它會(huì )因橋梁超載而變形，這不僅會(huì )影響橋梁的美觀(guān)，還會(huì )影響電纜的運行。正常情況下，電纜橋框架的承載能力由電纜橋框架的荷載特性曲線(xiàn)表示。從荷載曲線(xiàn)可以看出，承載能力與橋梁的規格和支撐距離有關(guān)，對應于相同的支撐距離和彎曲、凸起變形。側面高度大，承載力大。當承載能力相同時(shí)，相同規格、小支撐距離的電纜橋框架彎曲變形較小。
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.動(dòng)荷載是指橋架安裝和維護過(guò)程中，施工維修人員的重量。對于輕型電纜橋框架，一般不考慮動(dòng)荷載，即不允許人們站在橋梁框架上。如果需要考慮站人，跨度應該適當減小。
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.靜荷載是指敷設在山東電纜橋架內的電纜種類(lèi)、根數、每根的外徑重量/單位長(cháng)度，按電纜敷設的不同路由分別列表統計。
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.附加載荷是指僅在室外由冰、雪、風(fēng)和電磁力形成的載荷。它與安裝現場(chǎng)的自然氣象條件和帶電體的性質(zhì)有關(guān)。設計應根據各種條件進(jìn)行計算。
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.
橋梁可以獨立架設，當然，除此之外，它們還可以鋪設在各種建筑物和管架支架上。它們有許多特點(diǎn)和優(yōu)點(diǎn)，因為這不僅能體現出結構簡(jiǎn)單、外形美觀(guān)，而且還能表現出配置靈活、維護方便等特點(diǎn)。
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.
