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，還會(huì)影響電纜的安全運(yùn)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表示。從荷載曲線可以看出，承載能力與橋梁的規(guī)格和支撐距離有關(guān)，對(duì)應(yīng)于相同的支撐距離和彎曲、凸起變形。側(cè)面高度大，承載力大。當(dāng)承載能力相同時(shí)，相同規(guī)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(hù)過(guò)程中，施工維修人員的重量。對(duì)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(yīng)該適當(dāng)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(shè)在山東電纜橋架內(nèi)的電纜種類、根數(shù)、每根的外徑重量/單位長(zhǎng)度，按電纜敷設(shè)的不同路由分別列表統(tǒng)計(jì)。

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(xiàn)場(chǎng)的自然氣象條件和帶電體的性質(zhì)有關(guān)。設(shè)計(jì)應(yīng)根據(jù)各種條件進(jìn)行計(jì)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(dú)立架設(shè)，當(dāng)然，除此之外，它們還可以鋪設(shè)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?yàn)檫@不僅能體現(xiàn)出結(jié)構(gòu)簡(jiǎn)單、外形美觀，而且還能表現(xiàn)出配置靈活、維護(hù)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.
