桥架不同的角度是如何开展相连的？为了更好的使用该桥架您应该来看看这个问题内容，下面 山东电缆桥架厂家为您讲解。

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.

桥架直线段中间、直线段与弯通、变直接通间的连接件，应使用桥架生产厂配套连接件。连接件冷轧钢板薄厚不可低于桥架冷轧钢板薄厚。插口应整平，无歪曲、突起和凹痕，联接使用的半圆头镀锌螺栓，半圆头需在桥架里侧，螺栓长度适度，扭紧以后，外露长短以2～5牙合适。水准安装桥架，其直线段三通接头，应尽可能建在2个抗震支架间的1/4上下处。

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.

1.一般情况下没有在施工工地制做桥架。因为特殊情况必不可少时，可以利用已有的桥架改制非标弯通和变直接通。改制和断开直线段桥架时，均不得天燃气、电焊切割，运用专用型切割工具。改制的桥架务必整平，立即喷漆，油漆色调是与其他桥架相仿。

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.桥架超越建筑物的伸缩相接处，按GB50168要求，应设伸缩缝，确保桥架及铺设在桥架里的电缆线在建筑物伸缩不严重危害其自身安全性时可以随意伸缩，不会受到毁坏。由于新创建建筑物里，桥架组装一般都在钢筋混凝土工程项目进行数月乃至一年之后开展，混凝土收缩慢慢减少。伸缩量一般不能超过建筑物伸缩缝宽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.如果发现或从土建工程企业了解到了建筑物伸缩缝比较大有可能会超出L时，应按照实际搞好伸缩解决。要超越伸缩缝桥架少一侧有比较长的直线段，宜高于30m，或伸缩缝两边直线段桥架求和有30m，正中间无水准或竖直弯通。这样有利于在桥架中留电缆线(或电缆线)的伸缩容量，这一容量应超过伸缩缝宽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.
