Energy-consuming steel rod replaceable beam-column joint node and construction method thereof
PendingCN110258789AGood waterproof performanceEasy to connectProtective buildings/sheltersShock proofingRebarPre stress
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.
