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. 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. 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. 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. 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. 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.
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.
