1. The steel material must meet the design requirements. If there is no qualification or in doubt, the mechanical performance test and chemical analysis shall be carried out in accordance with the current national standard ≤Steel structure engineering construction and inspection standard ≥ GBJ205, and use it after proving that it meets the standards and design requirements. The quality of concrete should meet the requirements of the current national standard ≤ concrete structure engineering construction and inspection standard ≥  2. Space processing and installation shall comply with ≤ Space Structure Engineering Quality Inspection and Evaluation Standards≥ JGJ78-91, the construction plan design shall be formulated, and the construction shall be carefully implemented. 
2. All steel rulers used in the installation and testing of space frame processing and radiation transmission in civil engineering should be unified to make the measured tension consistent. When the span is large, the temperature should be adjusted according to the temperature condition.
3. Welding operations have been carried out in factories and prefabricated factories to reduce workload at heights and on-site. The on-site steel pipe welding shall be carried out by four or more technicians. After the welding technology of the welded ball joint and the steel pipe joint is inspected, all positions of qualified welding can participate in the construction. In order to reduce welding deformation and welding stress, a reasonable process sequence must be selected when using welded steel plate joints.
4. The installation method of the space frame should be determined according to the force and structural characteristics of the space frame, combined with local construction technical conditions, to meet the requirements of quality, safety, progress and economic benefits.
