In the horizontal bolt hole on the stud ball, the other side of the stud ball is fixed in the same way, and the basic mesh is connected with the hinged platform support as a whole, and forms a hinge with the hinged platform support;

e. Use a crane to lift the basic mesh, and use the hinge point formed by the non-threaded nut and the bolt ball to adjust the height and angle of the first section of the basic mesh, so that the workers can stand on the ground and form the basic mesh frame. The unit is installed together with the assembled end of the first basic mesh;

f. As the basic unit continues to be assembled with the basic mesh pieces across the grid at the beginning, the grid gradually lengthens along the span direction, and the crane also continuously increases the height of the grid to adjust the height of the mesh assembly end so that it is always at a suitable height from the ground It is convenient for workers to assemble the grid on the ground.

g. When the length of the post-assembled part of the grid to the crane is close to the distance from the crane to the bolted ball grid, the crane will re-place the hoisted grid on the ground, and the crane will move to the assembly end of the grid and change the rigging Re-lift at the hoisting position;

h. Repeat steps e, f, and g until all the basic spanning grids are fully assembled, and at the other end of the span, the grid support balls are in place, and the basic spanning grids are installed.

Compared with the prior art, the beneficial effect of the present invention is: the present invention uses a single crane to adjust the height and angle of the grid connected to the stud balls, making it suitable for assembly with the next section of the grid, effectively solving the problem of basic span installation. Scaffolding and multiple cranes are used for hoisting and assembly, which are prone to instability, bending, difficult construction, and inaccurate positioning. At the same time, the invention has simple structure, high safety, simple operation, and is economical and practical.
