We are working on improving the construction efficiency and quality of the bottom plate reinforcement method for fatigue damage in the welded joints of steel deck plates and U-ribs.
The "high-strength stud bolt" (equivalent to F8T) is a stud bolt suitable for one-sided construction applicable to friction joints. It can be used for joining members of steel structures and reinforcing against corrosion and fatigue damage with backing plates. Additionally, to ensure the quality and shape of stud welding on the underside of steel deck plates, a "stud upward welding system" has been developed. This system consists of an "upward stud welding device," "support rails," "templates," and "welding monitoring equipment." [Features of High-Strength Stud Bolts] ■ Reinforcement of members with closed sections or those with pavement/concrete on the back can be performed from one side only. ■ No drilling is required, preventing damage to existing members and avoiding a decrease in load-bearing capacity. ■ As a high-strength stud bolt for friction joints, it ensures the strength of bolt grade F8T. ■ With fastening tools for high-strength bolts, the specified bolt axial force can be reliably applied. ■ Patent number: 6556490 *For more details, please refer to the PDF document or feel free to contact us.
