The rivets used in the steel structure space frame components are made of riveted steel with good top forging performance, riveted connection, first made in the connected components than the nail diameter 1.0 ~ 1.5mm hole. Then one end of the rivet with a semi-circular nail head is heated until the rivet is cherry red when it is plugged into the hole, and then riveted with a rivet gun or riveting machine, so that the rivet fills the nail hole, and hit into another rivet head.
The rivet cools and shrinks after riveting, creating a clamping force on the connected plate bundle, which facilitates force transfer. The toughness and plasticity of riveted connections are better.
However, riveted joints are more labor-intensive and have more consumables and complex construction. It is currently used only for large span bolted ball space frame steel structures that are subjected to large dynamic loads.
In the factory almost replaced by welding, in the site almost replaced by high-strength bolted connections.
