What is the side sealing plate of steel space frame structure

The basic components of the space frame are rods and ball nodes. Their connection is mainly through bolts. When bolts and rods are connected, a steel space frame sealing plate and a cone are required. The steel space frame sealing plate is welded to the end of the rod; the components vary in size. When the structure is stressed, according to the design result, the function is the structure under tension or pressure. The “cone head” is an accessory used in the structure of the bolt ball steel grid, it is welded to the end of the steel pipe. The screw of the high-strength bolt is screwed into the bolt ball through the round hole at the bottom. The nut is inside the cone head, and the “sealing plate” the function is the same. When the diameter of the steel pipe is small, the “sealing plate” is used. When the diameter of the steel pipe is large, in order to avoid the collision between the steel pipes on the same bolt ball, the “taper head” is used. The “cone head” or “sealing plate” and steel pipe form the “rod” of the bolted ball space frame structure. Sometimes the “sealing plate” and “cone head” are collectively referred to as “head”.
