橋架不同的角度是如何開展相連的？為了更好的使用該橋架您應該來看看這個問題內容，下面山東電纜橋架廠家為您講解。

How are bridges connected from different angles? In order to better use the cable tray, you should take a look at this problem. The Shandong cable tray manufacturer will explain it to you.

橋架直線段中間、直線段與彎通、變直接通間的連接件，應使用橋架生產廠配套連接件。連接件冷軋鋼板薄厚不可低于橋架冷軋鋼板薄厚。插口應整平，無歪曲、突起和凹痕，聯接使用的半圓頭鍍鋅螺栓，半圓頭需在橋架里側，螺栓長度適度，扭緊以后，外露長短以2～5牙合適。水準安裝橋架，其直線段三通接頭，應盡可能建在2個抗震支架間的1/4上下處。

The connectors between the straight line section of the bridge and between the straight line section and the elbow and transformer shall be the connectors provided by the bridge manufacturer. The thickness of the cold-rolled steel plate of the connector shall not be less than that of the cold-rolled steel plate of the bridge. The socket shall be flat without distortion, protrusion and dent. The semicircle head galvanized bolt used for connection shall be on the inside of the bridge. The length of the bolt shall be appropriate. After tightening, the exposed length shall be 2~5 threads. For horizontally installed cable tray, its straight section tee joint shall be built at 1/4 of the upper and lower positions between two seismic supports as far as possible.

1.一般情況下沒有在施工工地制做橋架。因為特殊情況必不可少時，可以利用已有的橋架改制非標彎通和變直接通。改制和斷開直線段橋架時，均不得天燃氣、電焊切割，運用專用型切割工具。改制的橋架務必整平，立即噴漆，油漆色調是與其他橋架相仿。

1. Generally, no bridge is made on the construction site. When special circumstances are necessary, the existing cable tray can be used to make non-standard elbow and direct elbow. When restructuring and disconnecting the straight section bridge, natural gas and electric welding cutting shall not be allowed, and special cutting tools shall be used. The modified cable tray must be leveled and painted immediately. The paint color is similar to other cable trays.

2.橋架超越建筑物的伸縮相接處，按GB50168要求，應設伸縮縫，確保橋架及鋪設在橋架里的電纜線在建筑物伸縮不嚴重危害其自身安全性時可以隨意伸縮，不會受到毀壞。由于新創建建筑物里，橋架組裝一般都在鋼筋混凝土工程項目進行數月乃至一年之后開展，混凝土收縮慢慢減少。伸縮量一般不能超過建筑物伸縮縫寬L。

2. The expansion joint of the bridge beyond the building shall be set according to the requirements of GB50168 to ensure that the bridge and the cable laid in the bridge can be expanded at will without being damaged when the building expansion does not seriously endanger its own safety. In newly built buildings, the cable tray assembly is generally carried out months or even a year after the reinforced concrete project, and the concrete shrinkage is slowly reduced. Generally, the expansion amount shall not exceed the width L of the expansion joint of the building.

3.如果發現或從土建工程企業了解到了建筑物伸縮縫比較大有可能會超出L時，應按照實際搞好伸縮解決。要超越伸縮縫橋架少一側有比較長的直線段，宜高于30m，或伸縮縫兩邊直線段橋架求和有30m，正中間無水準或豎直彎通。這樣有利于在橋架中留電纜線(或電纜線)的伸縮容量，這一容量應超過伸縮縫寬L。

3. If it is found or learned from the civil engineering enterprise that the expansion joint of the building is likely to exceed L, the expansion shall be solved according to the actual situation. There are relatively long straight sections on the few sides of the bridge beyond the expansion joint, which should be higher than 30m, or the sum of straight sections on both sides of the expansion joint is 30m, and there is no level or vertical bending in the middle. This is conducive to reserving the expansion capacity of cable (or cable) in the bridge, which should exceed the expansion joint width L.
