According to the characteristics of its bearing capacity, Hexagon Flange Bolt can be divided into working pressure type and friction type. The calculation method is different.



　　 The stud bolt connection relies on the anti-shear stress of the anchor bolt rod and the working pressure of the hole to transmit the shear stress. The pre-tightening force required when tightening the nut is not large, and its effect can be ignored. In addition to the high compressive strength of the raw material, the high-strength bolt also releases a large pre-tension force, which causes squeezing pressure in the middle of the coupling. Therefore, the high-strength bolt is in the vertical position with the anchor bolt. , It will cause a lot of friction, and elements such as pre-tensioning, ground anti-skid index and steel type will immediately harm its bearing capacity.



　　 The minimum specification of stud bolts and high-strength bolts is M12, and the general application is M16~M30. The characteristics of large and medium-sized anchor bolts are unstable, so be careful when designing. Judging from the bearing force characteristics of Threaded Rods And Eye Bolts: High-strength bolts release pre-stressed steel bars and transmit external forces according to friction.
