Abstract

The invention discloses a fabricated beam-column connecting structure and a construction method. The beam column connecting structure comprises a fixed beam column, and a driving part is mounted on the side wall of the fixed beam column; the connecting beam column is hung on the driving part and located on one side of the fixed beam column, and the relative positions of the connecting beam column and the fixed beam column are adjusted through the driving part; the connecting triangular body is arranged on the connecting beam column and is provided with a first connecting piece connected with the fixed beam column and a second connecting piece connected with the connecting beam column; the tightening mechanism comprises a power source, a first tightening part and a second tightening part, and the first tightening part is aligned with the first connecting piece and connected with the power source so as to tighten the first connecting piece; the second tightening part is aligned with the second connecting piece and is connected with the power source so as to tighten the first connecting piece; and the limiting mechanism comprises a first limiting part and a second limiting part which correspond to the first connecting piece and the second connecting piece respectively for clamping and limiting. By means of the beam column connecting structure, assembling convenience, assembling efficiency and reliability can be improved.
