济南电缆桥架出现变形我们该如何解决呢?

现如今电缆桥架的应用给我们的生活带来了很大的帮助,电缆桥架是在自身的结构基础特点之上,将线缆附着于能够被支撑固定的建筑物上,由于其本身具有良好的抗老化、保温隔热、耐腐蚀、采光好的等特点受到了广大群众的青睐,它还能有效解决室内光线不足、节能降耗、环保等特点,但有时电缆桥架也会出现一些问题,比如变形,那么济南电缆桥架出现变形我们该如何解决呢?下面一起来看看吧
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、预应力方法:
1. Prestress method:
主梁下安装一套张拉装置,通过拉筋的拉力使主梁拱起。这样,主梁的下盖板产生压应力,上盖板产生拉应力,与外载荷产生的应力相反,抵消了部分工作应力,从而改善了主梁的受力状态。因此,预应力法具有加固主梁和修正下挠的目的。该方法简单,易于控制。它的缺点是有局限性,很难校正复杂的桥梁变形。
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:
火焰矫正法是加热桥梁的某些部位,被加热的部位会膨胀,但受到相邻未加热部位的限制,不能自由膨胀,所以被加热的部位会被压缩。冷却后,它会再次收缩。在冷却过程中,周围的金属被拉得彼此靠近,产生收缩力,该收缩力相当于作用在主梁中性层下的偏心力矩,从而使主梁恢复到上拱并校正结构变形。火焰校正方法灵活,能校正桥梁结构的各种复杂变形。
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.
以上就是济南电缆桥架出现变形后的两种解决方法,一种是预应力法,一种是火焰矫正法,这两种方法各有各的优点,也各有各的缺点,矫正时还是需要根据本身的情况来进行选择。以上内容介绍完了,后续有需要电缆桥架的朋友,可以了解一下我们网站的产品信息,有什么需要欢迎大家随时联系我们。
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. The above content is introduced, follow-up need cable tray friends, can understand our website product information, what need, welcome to contact us at any time.
