When the space frame is installed, the joint requirements between the accessories are very strict, so the size requirements for the accessories are very high.
The accuracy of the fabricating size of the space frame structure is the basis and prerequisite to ensure the accuracy of the overall structure size and the smooth installation of the steel structure space frame construction, and it is also a guarantee to ensure the stability of the overall structure of the steel structure space frame building.
When processing the grid, you must accurately grasp the size of the accessories and structure of the space frame. For example, the straightness and twist of the steel column, the distance between the connecting hole of the column and the beam and the column bottom plate, the processing accuracy of the connecting hole itself, the straightness of the roof beam and the processing accuracy of the column-beam connecting plate, the tie rod or support on the beam and column, the position and size of the connecting plate relative to the beam and column itself, the position and size of the purlin, etc.
For a space frame building, if the size of an accessory is deviated, it may cause problems with the stability of the entire site building. Therefore, the size of the accessory is a guarantee for the safety of the space frame building and must undergo strict testing.
