Reinforced concrete frame beam hogging moment region reinforcing method and reinforcing device
The invention discloses a reinforced concrete frame beam hogging moment region reinforcing method and a reinforcing device. The reinforcing device comprises a perpendicular supporting seat and a horizontal supporting seat, wherein the perpendicular supporting seat is fixed on a column member of a frame beam hogging moment region, and the horizontal supporting seat is fixed on a beam member of the frame beam hogging moment region. At least one energy-dissipating steel bar is arranged between the horizontal supporting seat and the perpendicular supporting seat, two ends of the energy-dissipating steel bars are connected with the perpendicular supporting seat and the horizontal supporting seat through clamp nuts respectively, the perpendicular supporting seat is fixedly connected with the column member through high-strength screws, the horizontal supporting seat is fixedly connected with the beam member through high-strength screws, pre-tension nuts are arranged on the high-strength screws, and buckling-restrained pipes sleeve the energy-dissipating steel bars. The reinforced concrete frame beam hogging moment region reinforcing method and the reinforcing device have the advantages that by the aid of the perpendicular supporting seat, the horizontal supporting seat and the energy-dissipating steel bars, anchoring reliability of the energy-dissipating steel bars is guaranteed, and replacement of the energy-dissipating steel bars is facilitated; the buckling-restrained pipes are arranged and filled with epoxy resin, so that the energy-dissipating steel bars are prevented from compressive buckling under the action of earthquakes; after reinforcement is completed, mortar is poured, and accordingly, the reinforcing device is protected from being corroded, and anchoring performance is enhanced.
