The main technical content
High rise and space steel structure technology: suitable for high rise buildings and large span space structure, including frame, frame support, cylinder and giant frame structure.
Light steel structure technology: suitable for light industrial plant, using color steel plate as wall and roof enclosure structure, with fast installation and light weight and high strength characteristics.
Steel-concrete composite structure technology: combines the advantages of steel and concrete to improve the overall strength, stiffness and seismic performance, suitable for multi-storey and high-rise buildings.
High-strength BOLted connection and welding technology: It provides a reliable connection method for steel structures, in which high-strength bolted connection is convenient for construction and disassembly, and welding can provide greater connection stiffness.
Method of connection
Steel structure of the main connection methods include weld connection, bolt connection and rivet connection.Each method has its unique advantages and disadvantages and is suitable for different structural needs and construction conditions.For example, weld connections can provide greater stiffness but may cause stress concentration;The bolt connection is easy to install and remove, suitable for the structure that needs to be installed and removed.
Welding and bolting details
Welding is one of the commonly used methods in steel structure connection, which is divided into manual arc welding, automatic or semi-automatic arc welding and gas shielded welding.There are various forms of weld, including butt weld and fillet weld.Bolt connection is divided into ordinary bolt connection and high strength bolt connection, the latter can be divided into friction type and pressure type.
