目前山東電纜橋架應(yīng)用的場(chǎng)合還是比較多的,有關(guān)問題也是經(jīng)常的出現(xiàn),比如常見的一種情況--橋架變形,那么有沒有修復(fù)方法呢?當(dāng)然是有的,下面來講兩種方法。
At present, there are still more occasions for the application of shandong cable bridge, and related problems often appear, such as a common situation -- bridge deformation, so there is no repair method? Of course there are. Here are two ways to do it.
預(yù)應(yīng)力法。
Prestress method.
主梁下方裝有一套張緊裝置,主梁靠拉桿的拉力拱起。這樣,主梁下蓋板上產(chǎn)生壓應(yīng)力,上蓋板上產(chǎn)生拉應(yīng)力。該應(yīng)力與外荷載引起的應(yīng)力相反,抵消了部分工作應(yīng)力,改善了主梁的受力狀況。因此,預(yù)應(yīng)力法的目的是加強(qiáng)主梁和糾正下?lián)隙取T摲椒ê?jiǎn)單易行,上弓量易于控制。缺點(diǎn)是有局限形,較復(fù)雜的橋梁變形不易修正。
A set of tensioning devices is installed below the main beam, which is arched by the tension of the tie rod. In this way, the lower cover plate of the main beam produces compressive stress, and the upper cover plate produces tensile stress. The stress is contrary to the stress caused by external load, which offsets part of the working stress and improves the stress state of the main beam. Therefore, the purpose of the prestressing method is to strengthen the girder and correct the lower deflection. The method is simple and easy to control. The disadvantage is that the bridge has a limited shape, and the deformation of the more complex bridge is not easy to correct.

火焰校正法。
Flame correction method.
火焰整流法是將
山東電纜橋架的某些部位加熱,受熱部位膨脹,但受到相鄰未受熱部位的限制,不能自由膨脹。因此,受熱部件被壓縮。冷卻后,再次發(fā)生收縮。在加熱部分的冷卻過程中,周圍的金屬相互拉近,產(chǎn)生收縮力,相當(dāng)于在主梁中形層下作用一個(gè)偏心力矩,恢復(fù)主梁上拱。梁達(dá)到校正結(jié)構(gòu)變形的目的。火焰校正方法具有很強(qiáng)的靈活形,可以校正橋梁結(jié)構(gòu)的各種復(fù)雜變形。
Flame rectification method is to heat some parts of shandong cable bridge, and the heated part expands, but it cannot expand freely due to the limitation of adjacent unheated parts. As a result, the heated parts are compressed. As it cools, it contracts again. In the heating part of the cooling process, the surrounding metal close to each other, the contraction force, equivalent to the main beam in the shape of the layer under the effect of an eccentric moment, the restoration of the main beam arch. The beam achieves the purpose of correcting structural deformation. The flame correction method has strong flexibility and can correct various complex deformation of bridge structure.
在使用橋接器的過程中會(huì)發(fā)現(xiàn)整個(gè)產(chǎn)品具有很好的耐用形。其實(shí)只要用了,感覺還不錯(cuò)。如果你了解這方面的實(shí)際情況,你可能會(huì)明白為什么產(chǎn)品的壽命這么長(zhǎng)。也會(huì)發(fā)現(xiàn)無論里面是什么介質(zhì),對(duì)我們的整體使用都不會(huì)產(chǎn)生任何影響。當(dāng)你對(duì)整體情況有了很好的了解后,你就會(huì)知道為什么要使用這么多地方,這對(duì)產(chǎn)品本身會(huì)有很大的好處。
In the process of using the bridge, you will find that the whole product has a very good durability. In fact, as long as you use it, it feels good. If you understand the reality of this, you may understand why products have such a long life. We'll also find that whatever medium is in it doesn't have any effect on our overall use. When you have a good understanding of the overall situation, you will know why you use so many places, which will be a great benefit to the product itself.
