The invention relates to an energy-consuming steel rod replaceable beam-column joint node and a construction method thereof, which comprises a frame column, a precast beam, a prestressing tendon, and a laminated floor.A prestressing tendon channel is formed in the prestressing beam; a through tendon channel is formedin the position corresponding to the prestressing tendon channel in the frame column; the prestressing tendon is arranged in the prestressing tendon channel and a through tendon channel; the bottom of the precast beam near the both ends is provided witha connecting component; the connecting component comprises a rectangular box which is enclosed by four vertical side plates and a top plate and a vertical connecting rod connected to the top of the rectangular box; a lower side of the vertical side plate near one side of the frame column is provided with a notch; a connecting channel is formed inthe position corresponding to the notch in the frame column; and an energy-consuming steel rod is worn in the connecting channel. The construction method solves the difficult technical problems, comprising complicated construction of the traditional beam-column joints, the inconvenient installation of the energy-consuming steel bars, the complicated installation of the energy-consuming steel bars in the upper part of the prefabricated beams, the poor integrity of the structural floor panels, the difficulty in waterproofing between the floors, the difficulty in replacing the connected components after the earthquake, and the structural repair after the earthquake.
Description
technical field [0001] The invention belongs to the field of construction engineering, in particular to a beam-column connection node with replaceable energy-consuming steel rods and a construction method thereof. Background technique [0002] At present, the domestic prefabricated concrete frame structure system mainly adopts beam-column disconnection at the node connection, prefabricated in sections, and the beam-column node area is cast in-situ at the construction site to form an assembled integral structural system. The dry connection system of beam-column joints is limited to setting corbels supporting prefabricated beams on prefabricated columns. The two are usually connected by steel plate embedded parts or inserted ribs, and the ability to transfer beam end bending moments is poor. Such joints with poor seismic performance are mainly used in plant structures. There are prefabricated prestressed frame dry joints without corbels used in civil buildings in the United S...
