Definition and purpose of bolts
Studs are high-strength and rigid fasteners used in various steel structure projects for rigid combination connections between different connectors. It uses arc stud welding to fix the cylindrical head welding nail on the connecting piece, which enhances the structural stability and load-bearing capacity.
Specification of bolts
The specifications of bolts are usually nominal diameters of 10mm to 25mm, and the total length before welding is 40mm to 300mm. This specification of bolt is suitable for connection requirements in various steel structure engineering.
Chemical composition and mechanical properties of bolts
Studs are usually made of low-carbon alloy steel, with chemical compositions including carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), etc. In terms of mechanical properties, the tensile strength of the bolt should not be less than 400N/mm ², the yield point should not be less than 320N/mm ², and the elongation rate should not be less than 14%.
Size and surface requirements for bolts
The size of bolts has specific regulations, such as minimum length, maximum length, diameter, etc. In addition, the surface of the bolt should be free of rust, oxide scale, grease, burrs, etc. The rod should not have cracks that affect its use, and the depth of the head cracks should not exceed a certain value.
National standard for bolts
The national standard for bolts is issued by the General Administration of Quality Supervision, Inspection and Quarantine of China, with the specific standard being GB/T10433-2002. This standard is applicable to shear resistant components, embedded components, and anchoring components of various structures in civil and construction engineering, and ensures the quality and safety of bolts.
Stud is a type of fastener used for high-strength and rigid connections in steel structure engineering, mainly applied in various steel structure constructions, serving as a rigid combination connection. The specification of the bolt is usually a nominal diameter of 10-25mm and a total length of 40-300mm before welding. It is the abbreviation of cylindrical head welding nail for arc stud welding, which is firmly embedded in concrete through welding technology and tightly connected to steel structure, thereby improving the bonding strength between the two materials, enabling more effective load transmission between steel and concrete, and enhancing the bearing capacity of the entire structure. The application of bolts is widespread, especially in large-scale projects such as high-rise buildings, bridges, and industrial plants, and is a key factor in ensuring structural stability. In addition, bolts can also improve the shear resistance of structures, especially under horizontal forces (such as wind loads and seismic actions), by resisting relative slip caused by shear forces, ensuring that the structure can maintain integrity under horizontal forces, and enhancing the seismic and wind pressure resistance of the structure.
