large span steel structure project

What are the connection methods for large-span steel structures that need to be connected during construction?

1. The prefabrication and assembly of steel components are carried out on the steel platform according to the installation sequence and process requirements, and the welding production quality must be determined. The spacing between the joint of the flange plate and the joint of the web plate of the section steel should be greater than 200mm.

2. Rivet connection: Rivet connection is the process of inserting a rivet with a semi-circular prefabricated nail head on one end, burning the nail rod red, into the nail hole of the connecting piece, and then using a rivet gun to rivet the other end into a nail head to achieve a secure connection.

3. Bolted connection: Bolted connection is a type of fastener that connects the connecting parts into a whole through bolts. There are two types of bolt connections: ordinary bolt connections and bolt connections. Advantages: The construction process is simple and easy to install, making it particularly suitable for on-site installation and connection, as well as easy disassembly. It is suitable for structures that require disassembly and temporary connections.

4. Welding seam connection: Welding seam connection is a process in which the heat generated by the arc causes the welding rod and the welded part to locally melt, and then cool and condense into a weld seam, thereby connecting the welded part into a whole.
