However, it should be understood that the specific embodiments described herein are merely for the purpose of explaining this utility and are not intended to limit the scope of this utility. In addition, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessary confusion in the concepts of this utility.

[0023] See Figure 1 The present invention provides a building seismic node connection structure, including a column 1, a beam 2 and a node connection unit 3 for connecting the column 1 and the beam 2, the node connection unit 3 including a support assembly 4 and a seismic assembly 5, the support assembly 4 including a support frame 41 for bearing the main impact, the support frame 41 is provided with an installation groove 411, the seismic assembly 5 includes two seismic parts 51 and four shock-absorbing parts 52, the seismic part 51 is arranged in the installation groove 411.

[0024] See Figure 2 Specifically, the support frame 41 includes a connecting base 412 and an assembly frame 413 integrally connected to the connecting base 412. The connecting base 412 is fixedly connected to the beam 2 by fasteners 414. The top surface of the assembly frame 413 is connected to the column 1. An arched plate 415 is provided under the assembly frame 413, and both ends of the arched plate 415 are connected to the connecting base 412.

[0025] See Figure 3 Specifically, the shock-absorbing member 52 includes a shock-absorbing rod 521, both ends of which are movably connected to the assembly frame 413 and the arched plate 415 through axial holes. A buffer gasket 522 is provided in the middle of the shock-absorbing rod 521, and the buffer gasket 522 is located between the assembly frame 413 and the arched plate 415.

[0026] See Figure 2 Specifically, the arched plate 415 includes an arched ring 416, and a connecting plate 417 is provided between the arched rings 416. The connecting plate 417 is connected to the beam 2. The arched ring 41 is more conducive to resisting force impact and has stronger earthquake resistance.

[0027] See Figure 4 Specifically, the anti-seismic component 51 includes an anti-seismic sleeve 511, a buffer rod 512 and an anti-seismic spring 513. The base of the anti-seismic sleeve 511 is fixedly connected to the mounting groove 411, one end of the buffer rod 512 is fixedly connected to the connecting plate 417, and the other end of the buffer rod 512 extends into the anti-seismic sleeve 511. The anti-seismic spring 513 is arranged on the buffer rod 512.

[0028] See Figure 4 Specifically, an air pressure chamber 5111 and a spring chamber 5112 are provided in the anti-seismic sleeve 511, a piston 514 is connected to the top of the buffer rod 512, the piston 514 is located in the air pressure chamber 5111 and is connected to the air pressure chamber 5111, and the anti-seismic spring 513 is located in the spring chamber 5112.

[0029] See Figure 4 Specifically, a limiting ring 5113 is provided between the air pressure chamber 5111 and the spring chamber 5112, and a limiting block 5121 is provided on the buffer rod 512.

When impacted, the anti-seismic spring 513 is compressed by the limiting ring 5113 and the limiting block 5121.

[0030] The working principle of the present invention is as follows: when the building vibrates, the column 1 and the beam 2 transmit the impact force to the supporting frame 41 of the connection node. After the supporting frame 41 is impacted, the anti-seismic component 51 bears the main impact, and the shock-absorbing components 52 on both sides buffer the aftermath. The anti-seismic component 5 and the shock-absorbing component 52 cooperate synchronously to buffer and absorb the vibration, thereby improving the anti-seismic performance of the connection node; in this process, the buffer rod 512 and the vibration sleeve 511 move relative to each other, and the anti-seismic spring 513 undergoes corresponding elastic deformation to buffer the impact force, and the piston 514 will cause piston movement in the air pressure chamber 5111 to compress or release the gas, further enhancing the buffering and anti-seismic effect.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
