How to build truss system?

The steps to build an aluminum alloy truss are generally divided into thirteen steps, and the specific steps are as follows:

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

2. Insert the bottom part of the oblique support on the outside of the base at the four corners, 2 at each corner, a total of 8;

3. Fix the reverse head to the base with screws, and pay attention to the rotation direction of the reverse head to be consistent with the marking in the figure;

4. Put the square sleeve on the reverse head;

5. Connect the beam on the ground;

6. Connect the two ends of the beam to the two square sleeves on both sides respectively. At this time, the beam part is assembled on the ground;

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

8. Several people slowly erect the column truss together, 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 hanging hoist to the beam below through the sling;

10. Four people slowly pull the hanging hoist together to pull the beam up to the left and right of the head;

11. Install the lighting and sound equipment on the beam;

12. Four 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 built.
