With its light weight and good seismic performance, steel structure plays a crucial role in modern architecture.Steel not only has excellent shock resistance and impact resistance, but also has a high degree of industrial production, so that components can be quickly and accurately assembled.
Steel structure steel mainly includes carbon structural steel, low alloy high strength structural steel, high quality carbon structural steel and alloy structural steel, etc.These materials are widely used in different structures and components according to their properties, such as high-rise buildings, long-span structures, and various specialized purpose structures.When choosing steel structural materials, it is necessary to ensure the load-bearing capacity of the load-bearing structure and to prevent brittle failure under specific conditions.
High-rise and space steel structure technology is suitable for high-rise buildings and large-span space structures, including frames, frame supports, tubes and giant frame structures.
Light steel structure technology is suitable for light industrial plant, using color steel plate as wall and roof envelope structure, with rapid installation and light weight and high strength characteristics.
The steel-concrete composite structure technology combines the advantages of steel and concrete, improves the overall strength, stiffness and seismic performance, and is suitable for multi-storey and high-rise buildings.
High-strength bolting and welding technology provides a reliable connection method for steel structures, where high-strength bolting is convenient for construction and disassembly, and welding can provide greater connection stiffness.
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.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. 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.
