According to SH 3531-2003, Ω-shaped anchor bolts should be welded on the outside of the straight sections, with each weld length being no less than 25 mm. 2. In GB 50474-2008: Ω-shaped anchor bolts shall be welded on both sides of the straight section, and the length of each weld shall not be less than 25 mm. 3. In SH 3609-2011: The omega-shaped anchor bolts shall be welded on the inside or outside of the straight section, and the length of each weld shall not be less than 25 mm. Current issues: 1. Is it necessary to weld on both sides of the straight section? Currently, testing shows that welding three points is sufficient to achieve a bent shape without the part coming apart; therefore, it is possible to weld on the inside or outside of the straight section in accordance with SH 3609. 2. The length of each weld on one side should not be less than 25 mm; the length of the straight edge of the anchor pin is approximately 17 mm. How can a weld on one side reach a length of 25 mm? Or should the total weld length be 25 mm (to ensure sufficient welding strength)? Ω anchor pin is shown in the figure below
