电缆桥架弯头45上下爬坡弯制作要注意什么

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。 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。
At present, the cable bridge elbow used in power construction is generally processed by the cable bridge factory before leaving the factory. However, due to the different conditions on the construction site, some projects need to process the cable bridge elbow according to local conditions, which requires the installation personnel to have some basic knowledge of construction to be competent. The cable bridge in construction site can be roughly divided into main bridge and bracket. The main bridge frame is designed by the design institute and constructed according to the drawings; the branch frame is the cable bracket which is led from the main bridge frame to the local equipment, without drawings, and is designed by the constructors according to the site conditions. Commonly used elbow types include: up and down jump 45 degrees, vertical up and down elbow, horizontal tee, etc.
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. The joint of elbow, jump and tee of self-made cable bridge frame should be fixed by spot welding on the inner side and polished with burr coating. The outer side should be smooth, and the gap should be as small as possible and the saw edge should be smooth and neat.

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. There are no wrong edges in the butt joint of cable bridge elbow. The butt joint after welding should be smooth and smooth, and there should be no burrs or sharp edges that damage the insulation layer of cable.
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 reinforcing bars to tray-type cable bridge, add 6-8MM round steel, and paint should be repaired both inside and outside. Before painting, the coating and welding slag should be cleaned up.
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 tees and elbows of the multi-layer cable bridge frame is completed, the bending angle should be on 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 making all self-made elbows, the rust-proof paint should be brushed at the cutting, polishing and welding points, and then the top paint with the same color as the bridge frame should be brushed.
