Abstract
The invention relates to an architectural structure node and in particular to an anti-seismic node of a reinforced concrete column beam. The anti-seismic node of the reinforced concrete column beam comprises a frame column. The frame column is outwards extended to form a bracket. Two ends of a frame beam between the frame columns are outwards extended to form a bulge part matched with the bracket. The upper surface of the bracket and the lower surface of the bulge part are provided with mutually matched grooves. Each groove is pre-embedded with an outer gear matched with an inner gear sheathed and fixed on a rotation shaft. The rotation shaft is fixed between the grooves through a fixing ring pre-embedded in the bracket. The split-type connection is formed between the frame column and the frame beam, so the beam end forms the plastic hinge structure in the earthquake, the node structure can be effectively protected, and the structure failure is prevented.
