Materials required to build a 12 * 6 * 6m light frame: 12 3m aluminum alloy trusses, 8 2m aluminum alloy trusses, 8 1m aluminum alloy trusses, 8 diagonal supports, 4 iron bases, 4 reverse heads, 4 square sleeves, 4 cross arms, 4 sling belts, 4 stage special hoist, screws, etc.
Note: The commonly used aluminum alloy truss column is 300 * 300MM section. If the truss beam is not hung with 300 * 300MM, if the span is large or the light is hung with 400 * 400 or 450 * 450.
Construction method of aluminum alloy light frame:
1. First place four bases roughly on the ground;
2. Insert the lower part of the diagonal support at the outer side of each base;
3. Fix the counter head on the base with screws;
4. Put a square sleeve on the reverse end;
5. Link the beams;
6. Connect the two ends of the beam with the two square sleeves on both sides, and then the beam is assembled on the ground;
7. Connect the column truss horizontally, and then screw one end on the reverse end and the other end on the cross arm. At the same time, connect the hanging hoist and the cross arm. The hoist is used to lift the lower beam truss;
8. Several people slowly erect the column truss together, pay attention not to push the column too hard, and then fix the screws on the counter head;
9. After the column is erected, hook the hook under the hoist to the lower beam through the sling;
10. Four people slowly pull the hanging hoist together to lift the beam to the left and right of the person's head;
11. Install lighting and sound equipment on the beam;
12. Four people pull the hoist to the preset height to stop;
13. Tighten one end of the diagonal support with the column, and the other end with the transverse support of the base, so that the gantry is completed.
Material deｓｃｒｉｐｔion: the diagonal brace is made of aluminum alloy, the cross bar is made of steel, the base is made of iron and aluminum, the cross arm is made of steel, and the truss, square sleeve, square head and reverse head are all made of aluminum alloy.
