The utility model discloses an articulated structure suitable for prefabricated concrete structure, including prefabricated component A, prefabricated component B and pre -cast screw, prefabricated component B need set up the reservation round hole, the pre -cast screw lower part is pre -buried in prefabricated component A, and its upper portion is passed pre -buried round hole, pre -cast screw pass through at the top billet and the nut is fixed, and this screw rod bears axial tension, prefabricated component A and prefabricated component B use unsmooth notch rotatable as the axis, become articulated structure, this notch acceptor level shear force, set up unsmooth notch between prefabricated component A and the prefabricated component B lap -joint, set up notch top surface multilayer oil felt pad between unsmooth notch, one end transversely can only set up one row of articulated structure in same prefabricated component B, can set up a plurality of articulated structures in one row to this row must be on same straight line. The utility model discloses can solve when prefabricated component is concrete member, the structure needs to concern reliably articulated between the component, and it is indeformable that the wall is found to the structure to the removable technical problem that waits of superstructure.
