The space frame structure need to use bolts for connection during installation , but the bolts are also different. The classification and characteristics of the bolted connection of the space frame steel structure as follows. There are two main types of bolted connections: ordinary bolted connections and high-strength bolted connections. Ordinary generally have two types: coarse bolts and refined bolts. The rough bolts are hot-pressed from round steel with rough surface.
Coarse bolts and refined bolts are not only different in screw rods, but also in hole walls. Bolt hole walls can be divided into first and second types of holes according to their quality. Rough bolts use second types of holes, and refined bolts use first types of holes.
High-strength bolt connection is a new form. It has the advantages of simple construction, removable, good mechanical performance, fatigue resistance, and no loosening under dynamic load. It is a promising connection method. The construction process of the bolt connection is simple, and the installation is convenient. Some of its advantages are bound to make it the most important connection method.
