The characteristics of aluminum alloy truss construction

1. First, place the four bases at the approximate positions on the ground, and adjust the legs below to make them in a horizontal plane;

2. Insert the bottom part of the diagonal support on the outside of the base on the four corners, and insert 2 pieces on each corner, for a total of 8 pieces;

3. Fix the reverse head on the base with screws. Note that the rotation direction of the reverse head should be the same as the one marked in the figure;

4. Put a square sleeve on the reverse head;

5. Connect the beams on the ground;

6. Connect the two ends of the beam with the two square sleeves on both sides respectively. At this time, the beam parts are assembled on the ground;

7. Connect the column truss flatly, then screw one end on the reverse head, and screw the cross arm on the other end, and at the same time link the hanging hoist and the cross arm, the function of the hoist is to lift the lower beam truss ;

8. Slowly erect the column truss with multiple people, be careful not to push the column with too much force, and then fix the screws on the reverse head;

9. After the column is erected, hook the hook under the hoist to the beam below through the sling;

10. 4 people slowly pull the hanging hoist together to pull the beam to the left and right of the person's head;

11. Install lighting and audio equipment on the beam;

12. 4 people pull the hanging hoist together to the predetermined height and stop;

13. Tighten one end of the inclined support to the column, and the other end to the horizontal support of the base, so that the aluminum alloy frame is completed.
