The steel structure grid member is one of the main grid fittings used in the grid construction project. After the grid construction project is completed, the rod member is to be inspected. Let's take a look at the requirements for the production and inspection of the lower rod together:
Production of rods:
In the welding * ball net frame, the rod and the ball are directly welded *, and in the bolt ball grid frame, the rod is connected to the sphere through the bolt. In addition to its own steel pipe, the rod also includes the sealing plate and cone that form the rod Head, sleeve and * strength bolt. Therefore, when considering the welding * shrinkage of the rod, the rod should be considered as a whole, and the allowable deviation value refers to the combined deviation.
Inspection of rods:
JGJ78-91 "Quality Inspection and Evaluation Standards for Grid Structure Engineering" controls the quality inspection standards of the rod itself and the components that make up the rod, according to the guarantee items and the allowable deviation items, respectively.
