The side wall of the threaded round cover 302 is provided with thread grooves 1 304 at equal distances. The fixing bolt 303 is threadedly connected in the thread groove 1 304 and the thread groove 2 306.

[0058] The four fixing frames 301 are respectively placed at the four corners where the assembly beam 2 and the assembly column 1 are connected. The fixing blocks 305 on the four fixing frames 301 are connected to each other to form a round block with threads. The threaded round covers 302 are threadedly connected to the four fixing blocks 305. Then, the fixing bolts 303 are threadedly connected into the thread groove 1 304 and the thread groove 2 306 corresponding to each other. The fixing bolts 303 limit the rotation of the threaded round covers 302 to prevent the threaded round covers 302 from being separated from the fixing blocks 305. The threaded round covers 302 tightly fix the four fixing blocks 305 together, so that the four fixing frames 301 are tightly fixed together. The four fixing frames 301 are fixed to the outside of the assembly column 1 and the assembly beam 2, so that the assembly column 1 and the assembly beam 2 are further better connected together.

[0059] The fixed frame 301 is composed of a snap-in frame 1 3001, a snap-in frame 2 3002 and a snap-in frame 3 3003.

[0060] The first clamping frame 3001 is clamped on the assembly beam 2 , the third clamping frame 3003 is clamped on the assembly column 1 , and the second clamping frame 3002 is clamped on the fixing protrusion 7 .

[0061] The shock absorbing fixed structure 4 includes a fixed frame 401, a rotating block 402, a shock absorbing damper 403, a connecting block 404, a threaded sleeve 405, a clamping groove 406 and a fixed frame 407. The fixed frame 401 and the clamping frame 3003 cooperate with each other, and the fixed frame 2 407 and the clamping frame 3001 cooperate with each other. The side walls of the fixed frame 401 and the fixed frame 407 are respectively rotatably connected with the rotating block 402, the shock absorbing damper 403 is fixedly connected to the side wall of the rotating block 402, and the other end of the shock absorbing damper 403 is fixedly connected to the connecting block 404. The side wall of the connecting block 404 is provided with an external thread, and the side wall of the connecting block 404 is provided with a clamping groove 406. The clamping grooves 406 on the connecting block 404 cooperate with each other, and the connecting block 404 is threadedly connected with a threaded sleeve 405.

[0062] The connecting block 404 on the fixed frame 1 401 is clamped together with the connecting block 404 on the same side of the fixed frame 2 407, and then the threaded sleeve 405 is threadedly connected to the two connecting blocks 404 clamped together. The threaded sleeve 405 can prevent the two connecting blocks 404 clamped together from being separated, so that a pull rod composed of a rotating block 402, a shock-absorbing damper 403 and a connecting rod is formed between the fixed frame 1 401 and the fixed frame 2 407. The pull rod can prevent the fixed frame 1 401 from being separated from the clamping frame 3 3003 and the fixed frame 2 407 from being separated from the clamping frame 1 3001, so that the connection between the assembly column 1 and the assembly beam 2 is more firmly established, and the shock-absorbing damper 403 can also buffer the vibration of the assembly beam 2 and the assembly column 1, thereby increasing the seismic effect of the entire beam-column node.

[0063] When the present invention is used, when connecting, the assembly beam 2 is inserted into the square through groove 13 on the fixed protrusion 7, and the plug-in protrusion 6 at the end of the assembly beam 2 is plugged into the plug-in groove 5 on the assembly column 1 for clamping;

[0064] Then, the threaded rod 1002 is rotated, and the threaded rod 1002 rotates to drive the clamping block 1001 to move, and the clamping block 1001 drives the limiting sleeve 1004 to slide on the limiting rod 1003. The limiting rod 1003 and the limiting sleeve 1004 can limit the rotation of the clamping block 1001, and the clamping block 1001 is lowered and inserted between the two sliding plates 1011 below. The sliding plates 1011 move toward both sides as the clamping block 1001 is inserted, and the spring 1015 is pressed against the clamping block 1001. When the sliding plate 1011 is compressed, the movement of the sliding plate 1011 drives the second clamping block 1014 to move. When the top of the threaded rod 1002 is completely screwed into the placement groove 8, the first clamping block 1001 is clamped into the second clamping groove 9 on the assembly beam 2, and the second clamping block 1014 is clamped into the third clamping groove 12 on the fixed protrusion 7. The assembly beam 2 is restricted by the first clamping block 1001 and the second clamping block 1014 to prevent the plug-in protrusion 6 from being separated from the plug-in groove 5, so that the assembly beam 2 and the assembly column 1 are better connected.

[0065] Then, four fixing frames 301 are placed at the four corners where the assembly beam 2 and the assembly column 1 are connected, the clamping frame 1 3001 is clamped on the assembly beam 2, the clamping frame 3 3003 is clamped on the assembly column 1, and the clamping frame 2 3002 is clamped on the fixing protrusion 7. The fixing blocks 305 on the four fixing frames 301 are connected to each other to form a round block with threads. The threaded round cover 302 is threadedly connected to the four fixing blocks 305, and then the fixing bolts 303 are threadedly connected into the thread groove 1 304 and the thread groove 2 306 corresponding to each other. The bolt 303 limits the rotation of the threaded round cover 302 to prevent the threaded round cover 302 from being separated from the fixing block 305. The threaded round cover 302 tightly fixes and connects the four fixing blocks 305 together, so that the four fixing frames 301 are tightly fixed and connected together. The four fixing frames 301 are fixed on the outer sides of the assembly column 1 and the assembly beam 2, further making the assembly column 1 and the assembly beam 2 better connected together, and making it convenient to make the assembly beam 2 and the assembly column 1 better fixed and connected together, while it is not necessary to open a large number of mounting holes on the side walls of the assembly beam 2 and the assembly column 1 body;

[0066] The fixing frame 301 can also block the top of the threaded rod 1002, which can better resist the threaded rod 1002 to prevent the threaded rod 1002 from moving upward, thereby preventing the clamping block 1001 from being separated from the clamping groove 2 9. The clamping block 1001 does not move and is blocked between the sliding plates 1011, which can prevent the clamping block 2 1014 from being separated from the clamping groove 3 12, thereby better ensuring that the clamping block 1001 is always clamped in the clamping groove 2 9, and the clamping block 2 1014 is always clamped in the clamping groove 3 12;

[0067] Then, the fixed frame 1 401 is sleeved onto the clamping frame 3 3003, and the fixed frame 2 407 is sleeved onto the clamping frame 1 3001, and then the connecting block 404 on the fixed frame 1 401 is clamped together with the connecting block 404 on the same side of the fixed frame 2 407, and then the threaded sleeve 405 tube is threadedly connected to the two clamped connecting blocks 404, and the threaded sleeve 405 tube can prevent the two clamped connecting blocks 404 from separating, so that a pull rod composed of a rotating block 402, a shock-absorbing damper 403 and a connecting rod is formed between the fixed frame 1 401 and the fixed frame 2 407, and the pull rod can prevent the fixed frame 1 401 from detaching from the clamping frame 3 3003 and the fixed frame 2 407 from detaching from the clamping frame 1 3001, so that the connection between the assembly column 1 and the assembly beam 2 is more firmly, and the shock-absorbing damper 403 can also buffer the vibration of the assembly beam 2 and the assembly column 1, thereby increasing the seismic effect of the entire beam-column node.
