电缆桥架在不同角度是怎么进行连接的?

桥架不同角度是怎么进行连接的?下面由小编带您了解一下!
How are bridges connected at different angles? Now let's take you to know!
桥架直线段之间、直线段与弯通、变径直通之间的连接件,应采用桥架制造厂配套的连接件。连接件薄钢板厚度不应小于桥架薄钢板厚度。
The connectors between the straight-line sections of the bridge, between the straight-line section and the elbow and reducer shall be the connectors matched by the bridge manufacturer. The thickness of thin steel plate of connector shall not be less than that of bridge.

接口应平整,无扭曲、凸起和凹陷,连接用的半园头镀锌螺栓,半园头应在桥架内侧,螺栓长度适当,拧紧之后,露出长度以2~5牙为宜。水平安装的桥架,其直线段的连接头,应尽量设在两个支吊架之间的1/4左右处。
The interface shall be flat without distortion, bulge and depression. The half round head galvanized bolt for connection shall be on the inner side of the bridge, and the bolt length shall be appropriate. After tightening, the exposed length shall be 2 ~ 5 teeth. For the horizontally installed bridge, the connector of the straight section shall be set at about 1 / 4 between the two supports and hangers as far as possible.
一般情况下不在施工现场制作桥架。由于特殊原因时,可利用现有的桥架改制非标准弯通和变径直通。
Generally, the bridge is not made on the construction site. For special reasons, the existing bridge can be used to restructure non-standard elbow and variable diameter straight through.
改制和切断直线段桥架时,均不得用气、电焊切割,应用专用切割工具。改制的桥架一定要平整,及时补漆,面漆颜色应与其它桥架相近。
When reforming and cutting the straight-line bridge, gas and electric welding shall not be used for cutting, and special cutting tools shall be used. The restructured bridge must be flat and repaired in time, and the finish color should be similar to that of other bridges.
桥架跨越建筑物的伸缩缝处,按GB50168规定,应设置伸缩缝,保证桥架及敷设在桥架内的电缆在建筑物伸缩不危及其本身时能自由伸缩,不受损坏。
At the expansion joints where the bridge crosses the building, expansion joints shall be set according to the provisions of GB50168 to ensure that the bridge and the cables laid in the bridge can expand freely without damage when the expansion of the building does not endanger itself.
因为新建建筑物里,桥架安装一般都在混凝土结构工程完成数月甚至一年之后进行,混凝土收缩逐渐减小。伸缩量一般不会超过建筑物伸缩缝宽L。
Because in new buildings, the bridge installation is generally carried out months or even a year after the completion of concrete structure engineering, and the concrete shrinkage decreases gradually. Generally, the expansion amount will not exceed the expansion joint width l of the building.
若发现或从土建单位了解到建筑物伸缩缝较大有可能超过L时,应按实际做好伸缩处理。
If it is found or learned from the civil engineering unit that the expansion joint of the building is large and may exceed L, the expansion treatment shall be carried out according to the actual situation.
要跨越伸缩缝的桥架至少一侧有较长的直线段,宜超过30m,或伸缩缝两侧直线段桥架相加有30m,中间无水平或垂直弯通。以便于在桥架中留电缆(或电线)的伸缩余量,这个余量应大于伸缩缝宽L。
At least one side of the bridge to cross the expansion joint has a long straight section, which should be more than 30m, or the sum of the straight sections on both sides of the expansion joint is 30m, and there is no horizontal or vertical bend in the middle. In order to reserve the expansion allowance of cable (or wire) in the bridge, this allowance shall be greater than the expansion joint width L.
