施工现场电缆桥架大致分为主桥架和分支架。主桥架是由设计院设计，根据图纸施工；分支架是由主桥架引到就地设备的电缆支架，没有图纸设计，根据现场情况由施工人员来设计的。常用的弯头种类包括：上下跳弯45°、垂直上下弯头、水平三通等。下面 山东电缆桥架厂家来讲讲桥架45°上下爬坡弯的有关制作内容：

The cable bridge at the construction site is roughly divided into main bridge frame and sub-frame. The main bridge frame is designed by the design institute and constructed according to the drawings; The sub-support is the cable support led from the main bridge to the local equipment. There is no drawing design, and it is designed by the construction personnel according to the site conditions. The commonly used elbow types include: jumping up and down 45 °, vertical up and down elbow, horizontal tee, etc. Next, Shandong cable bridge manufacturer will talk about the relevant manufacturing content of 45 ° up-and-down ramp of the bridge:

1.自制的电缆桥架弯头、跳弯、三通的连接处，应先在内侧进行点焊固定并把毛刺药皮打磨干净，外侧应平整，缝隙应尽量小且锯口处平整整齐。

1. For the connection of self-made cable tray elbow, jump bend and tee, spot welding shall be carried out on the inner side first and the burr coating shall be polished. The outer side shall be flat, the gap shall be as small as possible and the saw mouth shall be flat and tidy.

2.电缆桥架弯头对接无错边，焊接后的对口处应打磨平整、光洁，不应有损伤电缆绝缘层的毛刺、锐边等棱角。

2. The butt joint of the cable tray elbow shall be free of misalignment, and the butt joint after welding shall be polished and smooth, and there shall be no burrs, sharp edges and other edges that damage the cable insulation layer.

3.在托盘式电缆桥架内加钢筋时，采用增加Φ6-8MM圆钢，内、外侧都应补刷油漆。刷油漆前，应把药皮，焊渣清理干净。

3. When adding reinforcement in the tray type cable tray, add Φ The inner and outer sides of 6-8MM round steel shall be repainted. Before painting, the coating and welding slag shall be cleaned.

4.多层电缆桥架的自制三通及弯头安装完成后，折角应在垂直的统一直线上。

4. After the installation of the self-made tee and elbow of the multi-layer cable bridge, the bending angle should be in the vertical uniform straight line.

5.所有自制弯头制作完成后，应在切割、打磨、焊接处刷防锈漆，再刷与桥架颜色相同面漆。

5. After the fabrication of all self-made elbows, anti-rust paint shall be applied at the cutting, grinding and welding positions, and then the finish paint with the same color as the bridge.

目前电建施工中所使用的电缆桥架弯头一般是由电缆桥架厂在出厂之前完整加工好的，但是由于施工现场情况各不相同，所以有的项目需要因地制宜现场加工电缆桥架弯头，这就需要安装人员有一定的施工基础知识才能胜任。有关于电缆桥架的信息了解，就来我们网站 //www.comprepyme.com咨询吧！

At present, the cable bridge elbow used in power construction is generally completely processed by the cable bridge factory before leaving the factory. However, due to the different construction site conditions, some projects need to process the cable bridge elbow according to local conditions, which requires the installation personnel to have certain basic construction knowledge to be competent.
