Construction of Aluminum Alloy Truss

Construction of Aluminum Alloy Truss

1, first place four bases in the approximate position on the ground, adjust the following legs, so that it is in a horizontal plane;
2, Insert the outer side of the base on the four corners of the diagonal support under the part, each corner inserted 2, a total of 8;
3. Fix the reverse head on the base with screws, and pay attention to the rotation direction of the reverse head to be consistent with that marked in the figure;
4, put a good square sleeve on the reverse head;
5. Connect the beam on the ground;
6. The two ends of the beam and the two square sets on both sides are linked well, and the beam part is assembled on the ground at this time;
7, the column truss lying flat connected, and then one end of the screw on the reverse head, the other end of the screw on the cross arm, while the hanging hoist and the cross arm link, the role of the hoist is used to lift the beam truss below;
8, more than one person to slowly erect the column truss, be careful not to push the column too hard, and then fix the screws on the reverse head;
9. After the column is erected, the hook under the hanging gourd is hooked through the sling to the lower beam;
10, 4 people slowly pull the hanging gourd to pull the beam to the left and right position of the person's head;
11. Install lighting and sound equipment on the beam;
12, 4 people pull the hanging gourd together to the predetermined height stop;
13. Tighten one end of the diagonal support and the column, and tighten the other end and the transverse support of the base, so that the aluminum alloy frame is completed
