[0002] The reinforced concrete frame structure is one of the most common building structure forms in industrial and civil buildings. Among them, the node plays a role in distributing internal force, coordinating component deformation and maintaining the integrity of the structure in the structure bearing system.

The device can effectively absorb the energy of large earthquakes and small earthquakes through the setting of two working modes, thereby improving the seismic performance of the frame.

[0004] The scheme effectively absorbs the energy of large earthquakes and small earthquakes through the setting of two working modes, thereby improving the seismic performance of the frame, but the scheme does not have a structure for supporting the inside or outside of the building, thereby increasing the structure and effect of frame seismic resistance. When cracks occur in the concrete, the concrete may collapse from the inside due to the influence of the vibration force, thereby causing the outer wall to collapse. Therefore, the inside of the concrete needs to be reinforced, but the scheme does not have a structure for reinforcing the inside or outside of the building frame.

A method of seismic retrofitting of a reinforced concrete frame seismic retrofit structure, characterized by: The method is used for the reinforced concrete frame seismic reinforcement structure in any one of claims 1-5, and the method comprises the following steps: S1: frame installation; install the mounting ring at the clamping groove of the support column surface, limit the frame body to the surface of the support column, thereby supporting the support column through the support force generated by the frame body, fix the connecting plate to the ground through the first threaded hole and external screw, abut the support base to the base through threaded connection, adjust the installation angle of the connecting rod to the surface of the support column through the rotation of the connecting shaft along the inner surface of the mounting hole, then drill holes on the surface of the support column, abut one end of the connecting rod to the surface of the support column through the connecting external screw, and complete the frame installation process; S2: concrete pouring; pour the concrete from the pouring opening into the inside of the runner, fill the support column with concrete, increase the weight of the support column, and increase the support force of the support column on the frame body, and buffer the poured concrete through the buffer block to reduce the phenomenon of gaps or incomplete filling at the bottom of the support column during pouring; S3: plate body installation; after the pouring process is completed, pass the connecting bracket and the mounting plate through the air avoidance groove and the stepped groove to connect the bracket shaft installed on the surface of the connecting bracket to the connecting hole inside the mounting groove, complete the installation of the connecting bracket, the clamping plate, the support column and the frame body, install the clamping plate with the support column as the center point, form a closed space by installing a plurality of clamping plates, then pour concrete to pour the support column and the frame body inside the clamping plate forming a closed space with concrete, thereby supporting the concrete with the support column, the frame body, the connecting bracket and the clamping plate, and obtaining a reinforced concrete frame; S4: outer wall installation; before the concrete inside the reinforced concrete frame is preliminarily solidified, use the screw fixing method to make the screw penetrate the inside of the second threaded hole along the threaded hole, thereby completing the clamping plate and the outer wall plate installation process, then use the knocking push rod to make the push rod slide along the inner surface of the through hole and the inlay groove, and make the push rod push the inlay block under the action of the knocking force, thereby making the inlay block drive the taper block to embed into the inside of the concrete, increasing the contact points of the clamping plate and the concrete, and achieving the effect of anti-seismic reinforcement.

7. The anti-seismic reinforcement method of the reinforced concrete frame anti-seismic reinforcement structure according to claim 6, characterized in that: In S2, the concrete strength grade is C30-C35, the connecting bracket and the mounting plate are made of Q235 or Q345 steel, the steel strength standard value should have a guarantee rate of not less than 95%, the frame body is made of a frame or a diagonal bracing member with an anti-seismic level of one, two or three levels, the ratio of the tensile strength measured value to the yield strength measured value of the steel should be not less than 1.25, the ratio of the yield strength measured value to the yield strength standard value of the steel should be not greater than 1.3, and the total elongation rate measured value of the steel under the maximum tension should be not less than 9%; In S3, the clamping plate is made of Q235B grade steel or Q355B grade steel or aluminum plate or wood plate, the connecting rod is further fixed by welding after being fixed, the welding electrode type is one of E43, E50 or E55, and the connecting rod is welded before the frame installation and the concrete pouring.

8. The method for aseismic reinforcement of a reinforced concrete frame aseismic reinforcement structure according to claim 6, characterized in that: In the S4, the outer wall plate adopts Q235B or Q355B steel or aluminum plate or wood plate, the push rod and the embedded block adopt the inclined support component with the anti-seismic grade of one, two or three, the ratio of the measured value of the tensile strength of the steel bar to the measured value of the yield strength should not be less than 1.25, the ratio of the measured value of the yield strength of the steel bar to the standard value of the yield strength should not be greater than 1.3, and the total elongation rate of the steel bar under the maximum tension should not be less than 9%.
