the bottom end of the second damper is connected with the seventh connecting piece.
8. An assembled beam-column connecting node as defined in claim 7, wherein the other end of said first damper is connected to said eighth connecting piece.
9. An assembled beam-column connection node as defined in claim 7, wherein the other end of said second damper is connected to said fifth connecting piece.
10. The construction method of the assembled beam column is characterized by comprising the following steps:
(1) the column is internally provided with a column longitudinal rib, a first connecting piece, a column stirrup, an anchoring piece and a third connecting piece, the column stirrup is sleeved outside the column longitudinal rib and the first connecting piece to form a column frame, and the column frame, the anchoring piece and the third connecting piece are integrally cast and molded to form a column body of the prefabricated column; a section of the first connecting piece is reserved and arranged outside the column body;
(2) the prefabricated beam is internally provided with a beam longitudinal rib, a second connecting piece, a beam stirrup and a fourth connecting piece, the beam stirrup is sleeved outside the beam longitudinal rib and the second connecting piece to form a beam frame, and the beam frame and the fourth connecting piece are integrally cast to form a beam body of the prefabricated beam; a section of the second connecting piece is reserved and arranged outside the beam body;
(3) arranging a first damper on the third connecting piece, and arranging a second damper on the fourth connecting piece;
(4) hoisting the precast beam to enable one end of a second connecting piece positioned outside the beam body to be connected with one end of a first connecting piece positioned outside the column body in an embedded mode, connecting a second connecting piece with a third connecting piece, connecting the first connecting piece with a fourth connecting piece, connecting the anchoring piece with the second connecting piece, connecting the first damper with the fourth connecting piece, and connecting the second damper with the third connecting piece, so that the precast column and the precast beam are connected together.
