glass dome structure In the connection between the main parts of the steel beam and the steel beam of the dome structure , the traditional construction method has two forms. One is the direct welding on site . Second, the plate is fixed and then welded on site. C rane lifts the steel beam to the joint of another steel beam and the person welds it at high altitude and grinds it flat on site. Both of the above two methods require welding operation, and on-site welding has the following disadvantages: 1) welding operation requires on-site welding machine to pull wires, which is of high labor intensity and slow construction speed, time-consuming and laborious, and also increases labor cost;2) high-altitude welding is dangerous, easy to cause casualties and cannot guarantee welding quality;4) due to welding deformation and errors, the lighting glass above cannot be processed correctly. Generally, the frame is welded and installed, and the glass is ordered and produced afte...
