1. Bolted connection: Different parts of the pipe truss are connected together by bolts. This is a common and reliable connection method, which is suitable for large structures and occasions requiring disassembly. When connecting, it is necessary to ensure that the selection of bolts and pre-tightening force meet the design requirements.
2. Welded connection: Different parts of the pipe truss are permanently connected by welding. This connection mode can provide higher strength and rigidity, and is suitable for occasions where stable structures need to be fixed. When welding connection, attention should be paid to selecting appropriate welding methods and materials to ensure weld quality and structural integrity.
3. Splicing connection: Different parts of the pipe truss are spliced together by using pins, pins or sleeves. This connection method is often used for small pipe trusses, which is convenient to install and disassemble and the position of the connection point can be adjusted.
4. Node connection: Use special node connectors to connect different parts of the pipe truss. Joint connectors can provide higher stiffness and force balance, and can meet complex structures and special requirements.
When selecting the connection mode, it needs to be determined according to the specific application scenarios, design requirements and structural characteristics. At the same time, ensure that the connection mode meets the relevant building and safety standards, and be designed and evaluated by professional engineers to ensure the strength and structural stability of the connection.
