電纜橋架的承載能力受哪些因素？
電纜橋架框架由承載力有限的薄鋼板沖壓而成。它會(huì )因橋架超載而變形，這不僅會(huì )影響橋架的美觀(guān)，還會(huì )影響電纜的運行。在正常情況下，索橋框架的承載力由索橋框架的荷載特性曲線(xiàn)表示。從荷載曲線(xiàn)可以看出，承載力與橋架的規格和支承距離有關(guān)，對應于相同的支承距離和彎曲凸出變形。側面高度高，承載力大。在承載力相同的情況下，相同規格、小支撐距離的索橋框架的彎曲變形較小。
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.動(dòng)荷載是指橋架安裝和維護期間施工和維護人員的重量。對于輕型電纜橋架，一般不考慮動(dòng)荷載，即不允許有人站在橋架上。如果有必要考慮站著(zhù)的人，應該適當減少跨度。
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.靜荷載是指山東省電纜橋架內敷設的電纜種類(lèi)和數量，每根電纜的外徑重量/單位長(cháng)度，按不同的電纜敷設路線(xiàn)列出和計算。
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.附加荷載是指僅在室外由冰、雪、風(fēng)和電磁力形成的荷載。這與安裝現場(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 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.
橋架可以獨立架設。當然，此外，它們還可以鋪設在各種建筑物和管道支架上。它們有許多特點(diǎn)和優(yōu)點(diǎn)，因為它們不僅能體現結構簡(jiǎn)單、外形美觀(guān)，而且還表現出配置靈活、維護方便的特點(diǎn)。
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.
