Graded energy dissipation assembly type beam hinge joint

The invention discloses a graded energy dissipation assembly type beam hinge joint which comprises at least one pair of first embedded parts and at least one pair of second embedded parts, and the first embedded parts and the second embedded parts are distributed in the connecting direction of two precast beams. Each pair of first embedded parts and each pair of second embedded parts are arranged at intervals, and the ends of the two sides are used for being connected with precast beams correspondingly; the first embedded parts and the second embedded parts which are adjacent on the same side are connected through energy dissipation parts, the second embedded parts are provided with limiting holes and reserved stranded wire holes, and each pair of second embedded parts are connected through limiting bolt pins penetrating into the limiting holes and prestressed stranded wires penetrating into the reserved stranded wire holes. After being combined, the grading energy dissipation structures are matched with one
