Nowadays, the application of cable tray has brought great help to our life. The cable bridge is attached to the building which can be supported and fixed on the basis of its own structural characteristics. Because of its good anti-aging, heat preservation, heat insulation, corrosion resistance and good lighting, it has been favored by the masses. It can also effectively solve the problem of insufficient indoor lighting. , energy saving and consumption reduction, environmental protection and other characteristics, but sometimes cable tray will also have some problems, such as deformation, so how can we solve the deformation of cable bridge in Jinan? Let's have a look

1、預應力方法：

1. Prestress method:

主梁下安裝一套張拉裝置，通過(guò)拉筋的拉力使主梁拱起。這樣，主梁的下蓋板產(chǎn)生壓應力，上蓋板產(chǎn)生拉應力，與外載荷產(chǎn)生的應力相反，抵消了部分工作應力，從而改善了主梁的受力狀態(tài)。因此，預應力法具有加固主梁和修正下?lián)系哪康?。該方法?jiǎn)單，易于控制。它的缺點(diǎn)是有局限性，很難校正復雜的橋梁變形。

A set of tensioning device is installed under the main beam to arch the main beam through the tension of the tie bar. In this way, the lower cover plate of the main beam produces compressive stress, and the upper cover plate produces tensile stress, which is contrary to the stress generated by external load, offsetting part of the working stress, thus improving the stress state of the main beam. Therefore, the prestressed method has the purpose of strengthening the main beam and correcting the deflection. The method is simple and easy to control. Its disadvantage is that it has limitations and it is difficult to correct complex bridge deformation.
 

2.火焰校正方法：

2. Flame correction method:

火焰矯正法是加熱橋梁的某些部位，被加熱的部位會(huì )膨脹，但受到相鄰未加熱部位的限制，不能自由膨脹，所以被加熱的部位會(huì )被壓縮。冷卻后，它會(huì )再次收縮。在冷卻過(guò)程中，周?chē)慕饘俦焕帽舜丝拷?，產(chǎn)生收縮力，該收縮力相當于作用在主梁中性層下的偏心力矩，從而使主梁恢復到上拱并校正結構變形?；鹧嫘Ｕ椒`活，能校正橋梁結構的各種復雜變形。

Flame correction method is to heat some parts of the bridge. The heated part will expand, but restricted by the adjacent unheated parts, it can not expand freely, so the heated part will be compressed. As it cools, it shrinks again. In the cooling process, the surrounding metal is pulled close to each other, resulting in contraction force, which is equivalent to the eccentric moment acting on the neutral layer of the main beam, so that the main beam can be restored to the upper arch and the structural deformation can be corrected. The flame correction method is flexible and can correct various complex deformation of bridge structure.

以上就是濟南電纜橋架出現變形后的兩種解決方法，一種是預應力法，一種是火焰矯正法，這兩種方法各有各的優(yōu)點(diǎn)，也各有各的缺點(diǎn)，矯正時(shí)還是需要根據本身的情況來(lái)進(jìn)行選擇。以上內容介紹完了，后續有需要電纜橋架的朋友，可以了解一下我們網(wǎng)站的產(chǎn)品信息，有什么需要歡迎大家隨時(shí)聯(lián)系我們。

The above is Jinan cable bridge deformation after the two solutions, one is the prestressed method, the other is the flame correction method, these two methods have their own advantages, but also each has its own shortcomings, correction or need to choose according to their own situation.
