Main technical content
High-rise and space steel structure technology: suitable for high-rise buildings and long-span space structures, including frames, frame supports, barrels and giant frame structures.
Light steel structure technology: suitable for light industrial plants, the color steel plate is used as the wall and roof envelope structure, with fast installation and light and high strength characteristics.
Steel-concrete composite structure technology: combining the advantages of steel and concrete, improve the overall strength, stiffness and seismic performance, suitable for multi-storey and high-rise buildings.
High-strength bolt connection and welding technology: provides a reliable connection method for steel structures, in which high-strength bolt connection is easy to construct and disassemble, and welding can provide greater connection stiffness.
Connection method
The main connection methods of steel structure include weld connection, bolt connection and rivet connection. Each method has its own unique advantages and disadvantages and is suitable for different structural needs and construction conditions. For example, weld joints can provide greater stiffness but may cause stress concentration; Bolted connection is easy to install and disassemble, suitable for the need to install and disassemble the structure.
Weld and bolt connection details
Welding is one of the common methods in steel structure connection, which is divided into manual arc welding, automatic or semi-automatic arc welding and gas shielded welding. Welds come in various forms, including butt welds and fillet welds. Bolt connection is divided into ordinary bolt connection and high strength bolt connection, the latter can be divided into friction type and pressure type two.
