Winding assembly and welding of net frame

The work steps of the winding assembly and electric welding of the steel structure grid:

1. Put in the longitudinal members of the net frame of the winding plan view, and check whether the longitudinal parts and specifications of the winding ball are appropriate.

2. Put in the horizontal rods of the grid frame of the winding plan view, and check whether the horizontal position and specifications of the winding ball are appropriate.

3. According to the appropriate adjustment of the oblique web rod of the three-dimensional small assembly module, the longitudinal and transverse rods of the upper chord and the electric welding ball are properly in place. The way to adjust the oblique web rod is to not only laser cut too long rods, but also to open the angle of view of the cross rods with inverted chains, so that the rods are properly in place. Make sure that the winding grid is properly sized.

4. Adjust the gaps everywhere, and weld the upper chords after the foundations of the gaps meet the standards.

5. After the upper chord member is fixed, weld the lower chord ball and the crossbar to make the connection firm.

6. Gradually check the grid specifications and push forward gradually. The installation of the web rods of the grid frame and the chord rods of the grid frame should be carried out in coordination with each other.

7. After the steel structure grid pavement is installed, the engineering acceptance should be carried out according to the overall specifications of the bars or blocks where the grid is installed.

8. The net frame to be hoisted must be hoisted (improved) after the electric welding welding process is finished, the welding appearance quality, and the welding ultrasonic flaw detector report reaches the standard.
