The grid is a spatial structure formed by multiple rods connected by nodes in a certain grid form. At present, it is widely used in the roofs of buildings such as stadiums, theaters, exhibition halls, waiting halls, stadium stands, hangars, and two-way large-pillar workshops. Today I will tell you about the preparation work before the grid construction:

1. Check the grid support axis and elevation before the grid construction. The grid axis and elevation position must meet the design requirements and relevant standards.
2. Check the concrete strength of the support before the grid construction. The concrete strength must meet the design requirements and the current relevant standards before installation.
3. Set up full house red scaffolding, and arrange the position and elevation of each fulcrum. And design and arrange the temporary fulcrum, the location and quantity of the temporary fulcrum are confirmed by checking calculation.
4. Use jacks to adjust the height of the net frame gradually.
