Problems solved by technology

At present, it is common to increase the bearing capacity of beam-column joints by increasing the cross-section of the beam-column or adding reinforcement materials. The former alone increases the shear cross-sectional area of ​​the core area of ​​the joint, thereby improving the shear strength and stiffness, but it is not effective for earthquakes to a certain extent. It has the effect of amplification, which is not conducive to earthquake resistance. The latter basically does not increase the cross-sectional area, but it requires a higher level of operation, and the construction process is more complicated, so it is difficult to control the overall effectiveness of reinforcement.

Abstract

The invention provides a frame beam-column anti-seismic reinforcing structure and a construction method thereof, and relates to a beam-column reinforcing structure and a construction method thereof. The portion, adjacent to the lower portion of frame beams, of a frame column externally expands to be provided with a variable cross-section reinforcing section, beam end reinforcing groove steel plates are matched and surrounded on the position, adjacent to the frame column, of the frame beam and are fixedly connected with a floor and the variable cross-section reinforcing section, each energy dissipation reinforcing member comprises two arc-shaped shearing steel plates with the perpendicular angle, the lower ends of every two arc-shaped shearing steel plates are connected into a whole throughan angle steel part, each angle steel part is fixedly connected with the corresponding corner of the variable cross-section reinforcing section, the upper end of every two arc-shaped shearing steel plates and the corresponding beam end reinforcing groove steel plate are fixed into a whole, a U-shaped buffer groove is bent in the middle of each arc-shaped shearing steel plate, openings of every two adjacent U-shaped buffer grooves are formed oppositely, and a composite elastic block is tightly fixed between the openings of every two adjacent U-shaped buffer grooves through a fastening threadedrod. The frame beam-column anti-seismic reinforcing structure and the construction method thereof have the advantages that the structure is simple and efficient, the construction is convenient, and the anti-seismic property can be improved.

Description

technical field [0001] The invention relates to a beam-column reinforcement structure and a construction method, in particular to a frame beam-column anti-seismic reinforcement structure and a construction method. Background technique [0002] The frame structure is a load-bearing system composed of beams and columns, and the walls only play the role of enclosure and separation without load-bearing, so it has the advantage of flexible space layout and is widely used in the field of housing construction. [0003] In the frame structure, the frame composed of beams and columns jointly resists horizontal loads and vertical loads. The beam-column joints play a pivotal role and are the key to transmitting internal forces. Therefore, when the beam-column joints are damaged by external forces such as material aging or earthquakes, seismic reinforcement maintenance is required Ensure building safety. At present, it is common to increase the bearing capacity of beam-column joints by...
