Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The reinforcement assembly 7 includes a reinforcement plate 1 71, the outer wall of which is fixedly connected to the inside of the steel bar column 1, the damping element 72 is rotatably connected to the inside of the reinforcement plate 1 71, the outer wall of the damping element 72 is rotatably connected to the connection shell 73, the outer wall of the connection shell 73 is rotatably connected to the inside of the reinforcement plate 1 71, the connection shell 73 is rotatably connected to the inside of the connection block 74, the outer wall of the connection block 74 is rotatably connected to the reinforcement plate 2 75, and the inside of the reinforcement plate 2 75 is rotatably connected to the outer wall of the reinforcement plate 1 71. The reinforcement assembly 7 also includes a positioning block 76, the outer wall of the positioning block 76 is fixedly connected to the outer wall of the reinforcement plate 2 75, the outer wall of the positioning block 76 is slidably connected to the inside of the positioning hole 8, and the fixing assembly 9 is arranged inside the reinforcement plate 2 75.

[0024] Specifically, firstly, the steel bar column 1 and the steel bar column 2 are connected, and the outer wall of the positioning block 76 is slid into the inside of the positioning hole 8. When the positioning block 76 is completely slid into the inside of the positioning hole 8, the connection between the steel bar column 1 and the steel bar column 2 is completed. Then, the steel plate 3 is attached to the outer wall of the steel bar column 1 and the steel bar column 2 to cover the connection between the steel bar column 1 and the steel bar column 2. Then, the high-strength bolt 4 is inserted into the screw hole 6 inside the steel bar column 1 and the steel bar column 2 after passing through the steel plate 3. Finally, the high-strength bolt 4 is tightened with the M20 self-locking nut 5 to fix the steel bar column 1 and the steel bar column 2. The reinforcement component 7 inside 1 is installed inside the steel column 1 and the steel column 2 at the same time. By utilizing the characteristics of the damping element 72, and then performing rotation buffering through the cooperation of the damping element 72, the connecting shell 73 and the connecting block 74, the vibration generated by the steel column 1 and the steel column 2 can be absorbed. Through the shock absorption technology, the frame structure can produce a certain plastic deformation to prevent brittle failure, thereby significantly improving the ductility and seismic resistance of the structure; in addition, the shock absorption device can effectively control the inter-layer displacement angle, reduce the influence of excessive lateral displacement on the overall structure, and avoid overall structural failure or even continuous collapse caused by damage to local nodes.

[0025] Please see attached Figure 5 -Attached Figure 6 In a preferred embodiment of the present invention, the fixing assembly 9 includes a spring 91, which is arranged inside the reinforcing plate 75, and the outer wall of the spring 91 is fixedly connected with a fixing block 92, and the outer wall of the fixing block 92 is slidably connected inside the reinforcing plate 75, and the end of the fixing block 92 away from the spring 91 is provided with an arc 93.

[0026] Specifically, when the reinforcing assembly 7 is installed, when the outer wall of the fixing block 92 touches the outer wall of the steel bar column 2, since the outer wall of the fixing block 92 is designed with an arc 93, the steel bar column 2 will push the fixing block 92 to compress the spring 1 91. When the fixing block 92 passes through the fixing groove 10, the spring 1 91 will rebound and push the fixing block 92 into the inside of the fixing groove 10 to get stuck; thereby, the effect of strengthening and fixing the steel bar column 1 and the steel bar column 2 can be achieved. The fixing block 92 can accurately enter the fixing groove 10 of the steel bar column 2 and get stuck firmly through the arc design of its outer wall and the compression-rebound characteristics of the spring 1 91. This design realizes the efficient docking and fixation of the steel bar column 1 and the steel bar column 2, greatly improves the stability of the node, prevents the connection from loosening or failing due to vibration, and thus enhances the seismic performance of the overall structure.

[0027] Please see attached Figure 6 In a preferred embodiment of the present invention, the connection assembly 11 includes a housing 111, the outer wall of the housing 111 is fixedly connected to the inside of the steel column 2, the inside of the housing 111 is fixedly connected to a pillar 112, the outer wall of the pillar 112 is rotatably connected to a clamp 113, the outer wall of the pillar 112 is rotatably connected to a clamp 2 114, and the outer walls of the clamp 1 113 and the clamp 2 114 are both connected to a spring 3 115. The outer wall of the spring 3 115 is fixedly connected to the outer wall of the housing 111. The connection assembly 11 also includes a connection plate 116, the outer wall of the connection plate 116 is fixedly connected to the two ends of the steel column 1, and the outer wall of the connection plate 116 is arranged inside the clamp 1 113 and the clamp 2 114.

[0028] Specifically, when the steel column 1 and the steel column 2 are being installed, the connecting plate 116 will squeeze the clamp 113 and the clamp 2 114. When the clamp 113 and the clamp 2 114 are squeezed by the connecting plate 116, the spring 3 115 will be compressed and rotate on the outer wall of the pillar 112. When the steel column 1 and the steel column 2 are installed, the connecting plate 116 will completely enter the interior of the clamp 113 and the clamp 2 114. At the same time, the spring 3 115 will rebound to fix the clamp 113 and the clamp 2 114 to fix the connecting plate 116 inside. Thereby, the positioning block 76 and the fixing block 92 can be used to achieve the upper, middle and lower three-layer fixing effect, and it is convenient to install the steel plate 3. The upper, middle and lower three-layer fixing structure effectively improves the shear resistance of the node, simplifies the installation steps of the steel plate during construction, and significantly improves the connection stability and assembly efficiency of the structure.

[0030] Specifically, when installing the steel plate 3 and the high-strength bolt 4, the flat washers 12 are placed at both ends of the high-strength bolt 4, and the spring washers 13 are placed on one side of the M20 self-locking nut 5, and the M20 self-locking nut 5 is tightened. Finally, the installation is completed and the next step can be carried out; in the connection between the steel plate 3 and the high-strength bolt 4, the pressure of the bolt is evenly dispersed by the flat washers 12, and the spring washers 13 provide additional friction, which effectively prevents the nuts from loosening under earthquakes or long-term vibrations. This design not only ensures the connection reliability of the bolts, but also reduces the stress concentration at the nodes, thereby protecting the integrity of the connection parts and extending the service life of the frame structure.

[0031] A construction method for a highly seismic cast-in-place reinforced concrete frame structure comprises the following steps: S1. Connect the steel bar column 1 and the steel bar column 2, first slide the positioning block 76 into the positioning hole 8, and after completing the connection, fit the steel plate 3 to the outer wall of the steel bar column 1 and the steel bar column 2 to cover the connection, then insert the high-strength bolt 4 through the steel plate 3 into the screw hole 6, and tighten and fix it with the M20 self-locking nut 5, and at the same time install the reinforcement component 7 inside the steel bar column 1 to the inside of the steel bar column 1 and the steel bar column 2, and use the damping element 72 and the connection shell 73 and the connection block 74 to buffer and absorb the vibration generated by the steel bar column 1 and the steel bar column 2; S2. When installing the reinforcement assembly 7, the fixing block 92 touches the outer wall of the steel column 2 and then compresses the spring 1 91. When the fixing block 92 enters the fixing groove 10, the spring 1 91 rebounds and pushes the fixing block 92 to be firmly stuck into the fixing groove 10; S3. During the installation process, the connecting plate 116 squeezes the clamping jaw 113 and the clamping jaw 2 114, compresses the spring 3 115 and drives the support 112 to rotate. When the steel column 1 1 and the steel column 2 2 are installed, the connecting plate 116 completely enters the inside of the clamping jaw 113 and the clamping jaw 2 114, and the spring 3 115 rebounds to fix the clamping jaw 113 and the clamping jaw 2 114 to the connecting plate 116; S4. When installing the steel plate 3 and the high-strength bolt 4, place washers 12 at both ends of the high-strength bolt 4, and place spring washers 13 on the side of the M20 self-locking nut 5. Finally, tighten and fix, and then proceed to the next step.

[0032] Specifically, during the construction process, first ensure the accurate docking of each component, including the precise installation of the positioning block 76 sliding into the positioning hole 8, and the stable connection of the steel column 1 and the steel column 2. The damping element 72 cooperates with the connecting shell 73 and the connecting block 74 to effectively absorb energy under vibration, reduce the brittle failure of the structure, and control the inter-layer displacement angle to avoid continuous collapse of the structure. At the same time, the multi-layer fixed structure further enhances the stability of the node, and combined with the role of the high-strength bolts 4 and the flat washers 12, significantly improves the seismic performance and service life of the overall frame structure.
