To provide a biaxial connector for concrete products, wherein bolt axial lines are deflected toward a product side surface to facilitate work time saving, safety and saving, and wherein tightened crossing bolts have spring elastic force, tensile and shearing resistance bearing forces.
The system consists of a biaxial connector and two bolts; the former comprising an anchor 13 at one end, a contact surface 14 perpendicular to the axis line S1 of the anchor 13 at the other end; pressure seat units 22 and 23 inclined in a chevron shape to the axial line are provided at the inside of the contact surface; a bolt hole 26 perpendicular to the front-side pressure seat unit 22 is opened to the longitudinal center line V of contact surface 14, and a female-screw bolt hole 28 perpendicular to the rear-side pressure seat unit 23 is opened to the longitudinal center line V of the contact surface at an angle symmetrical with the bolt hole 26; and bolts 30 are inserted from the front sides of two connectors and tightened crossing each other in the X- shaped form at both sides of the axial line S1.
