A limiting block is fixedly connected to the inner wall of the fixing block, and a pressing block is fixedly connected to the outer surface of the limiting block. A limiting groove is formed at the side end of the steel beam, and a fixing groove is formed on the outer side of the steel beam. This connection device for steel structure nodes, through the design of the fixing block, limiting block, pressing block, limiting groove, fixing groove, insert block, threaded rod, and rotating rod, allows for quick connection of the steel beam and column during use, greatly increasing the overall effectiveness of the device.

[0004] Traditional steel structure node connection methods involve multiple steps and complex operations, resulting in lengthy connection processes and reduced construction efficiency. Some connection devices lack effective limiting and clamping mechanisms, causing steel beams to easily sway or shift after connection, affecting the overall stability of the steel structure. Complex connection processes or unstable connections increase safety hazards during construction, threatening the safety of operators. Some connection devices are poorly designed, making it difficult to disassemble and reinstall steel beams when maintenance or replacement is needed, increasing construction difficulty and cost. Therefore, a new connection device for steel structure nodes is needed to solve these problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3This utility model discloses a connection device for a steel structure node, including a steel column 1, a steel beam 2, and a quick connection device 3. The quick connection device 3 includes a sliding rod 301, a top cover 302, a first limiting tooth 303, a connecting frame 304, a limiting ring 305, a connecting bolt 306, a clamping plate 307, a mounting groove 308, a spring 309, a nut 310, and a second limiting tooth 311. The top cover 302 is fixedly installed on the top of the connecting frame 304. Multiple first limiting teeth 303 are evenly distributed on the inner wall of the connecting frame 304 near one side of the periphery. The bottom of the top cover 302 has a mounting groove. A spring 309 is fixedly installed on the inner top wall of the mounting groove 308 near the middle. A clamping plate 307 is fixedly installed on the bottom of the spring 309. A sliding rod 301 is fixedly installed on the top of the clamping plate 307 near the left and right sides. A limit ring 305 is provided on the outer surface of both sliding rods 301. A connecting bolt 306 is threadedly connected to the middle of the top of the top cover 302. A nut 310 is threadedly connected to the connecting bolt 306. A quick connection end 4 is fixedly connected to one side of the steel beam 2. A limit pattern 5 is provided on the outer surface of the quick connection end 4 near one end of the steel beam 2.

[0022] Specifically, the tops of the two slide rods 301 extend through the inner top wall of the mounting groove 308 near the left and right sides and out of the top of the cover 302, and the connection between the slide rods 301 and the cover 302 is a movable sleeve.

[0023] Specifically, the internal movable sleeve of the mounting groove 308 of the clamping plate 307.

[0024] Specifically, a threaded groove is provided at the top center of the quick-connect end 4, and a second threaded groove is provided at the center of the inner bottom wall of the connecting frame 304. When the quick-connect end 4 is inserted into the connecting frame 304, the bottom of the connecting bolt 306 passes through the top cover 302, the clamping plate 307, the threaded groove on the quick-connect end 4, and the second threaded groove on the connecting frame 304, and is connected to the connecting bolt 306 through the nut 310.

[0025] Specifically, the connection between the connecting bolt 306 and the clamping plate 307 is a movable sleeve, and the connecting bolt 306 passes through the interior of the spring 309 during use.

[0026] Specifically, multiple second limiting teeth 311 are arranged side by side at the bottom right side of the clamping plate 307, and multiple first limiting teeth 303 and second limiting teeth 311 are all elastic.

[0027] Specifically, there are four steel beams 2, and the four steel beams 2 have the same structure.

[0028] Specifically, there are four quick-connect devices 3, and the four quick-connect devices 3 have the same structure. The four connecting brackets 304 are fixedly connected to the periphery of the steel column 1 respectively.

[0029] In use, this steel structure node connection device provides two convenient connection methods to ensure a stable connection between the steel column 1 and the steel beam 2. Method 1: The upper cover 302 is removed for connection. First, the operator gently removes the upper cover 302 from the connecting frame 304. This exposes the internal space of the connecting frame 304, facilitating the subsequent insertion of the quick-connect end 4. Next, align the quick-connect end 4 on the steel beam 2 with the upper opening of the connecting frame 304 and slowly insert it into the connecting frame 304. During this process, special attention must be paid to the matching of the position of the quick-connect end 4 with the internal structure of the connecting frame 304 to ensure smooth subsequent connection operations. Then, the upper cover 302 is replaced on the connecting frame 304 and fixed to it with bolts. During the process of replacing the upper cover 302, the limiting pattern 5 interacts with the first limiting tooth 303 and the second limiting tooth inside the connecting frame 304. The teeth 311 engage, effectively enhancing the stability of the connection and preventing the quick-connect end 4 from shaking or shifting during the connection process. Subsequently, after the top cover 302 is securely closed, the elastic force of the spring 309 pushes the clamping plate 307 to clamp and fix the quick-connect end 4 inside the connecting frame 304. This step is crucial to ensuring the stability of the quick-connect end 4 inside the connecting frame 304, effectively preventing any displacement or loosening during subsequent operations. Finally, the connecting bolt 306 passes through the top of the top cover 302, the top of the clamping plate 307, the threaded groove in the quick-connect end 4, and the second threaded groove on the connecting frame 304, extending to the bottom of the connecting frame 304. Then, the nut 310 is threadedly connected to the connecting bolt 306 at the bottom of the connecting frame 304, thereby further strengthening the connection between the steel column 1 and the steel beam 2, ensuring the stability and safety of the entire structure.Method 2: The top cover 302 can be connected without removal. In this method, the operator does not need to remove the top cover 302 from the connecting frame 304 and can directly perform the connection operation, greatly improving connection efficiency. First, align the quick-connect end 4 on the steel beam 2 with the opening of the connecting frame 304 and slowly insert it into the interior of the connecting frame 304. At this time, the elastic characteristics of the first limiting tooth 303 and the second limiting tooth 311 are fully utilized. During the insertion process, the quick-connect end 4 can fit tightly with the internal structure of the connecting frame 304. Specifically, when the quick-connect end 4 is inserted into the connecting frame 304, the side of the first limiting tooth 303 near the inner wall of the connecting frame 304 will fit tightly against the inner wall of the connecting frame 304, and at the same time, the side of the first limiting tooth 303 near the bottom of the clamping plate 307 will also fit tightly against the bottom of the clamping plate 307. During this process, the clamping plate 307 will be compressed into the mounting groove 308, the spring 309 will also be compressed at the same time, and part of the slide rod 301 will slide along the top... The cover 302 extends beyond the top of the upper cover 302; this design not only ensures the smooth insertion of the quick-connect end 4, but also provides sufficient elasticity for subsequent clamping and fixing; after all the quick-connect ends 4 are inserted into the connecting frame 304, the pressure disappears, and the elasticity of the spring 309 will quickly push the clamping plate 307 to clamp and fix the quick-connect ends 4 inside the connecting frame 304; at the same time, the first limiting tooth 303 and the second limiting tooth 311 will lock the limiting pattern 5, further ensuring the stability of the quick-connect ends 4 inside the connecting frame 304; finally, the operator can easily tighten and fix the quick-connect ends 4 to the upper cover 302 and the connecting frame 304 respectively with the connecting bolts 306 and nuts 310, thereby completing the entire connection process; this method not only eliminates the steps of removing and putting on the upper cover 302, improving connection efficiency, but also fully ensures the stability and safety of the connection, providing a strong guarantee for the rapid construction of steel structure projects.

[0030] In summary, the connection device for this steel structure node, through the inclusion of the quick-connect device 3, simplifies and expedites the connection process between the steel column 1 and the steel beam 2. Whether the connection is achieved by removing the top cover 302 or without removing it, the connection time is significantly reduced, improving construction efficiency. The engagement of the limiting teeth {first limiting tooth 303 and second limiting tooth 311} with the limiting groove 5 in the quick-connect device 3, and the clamping and fixing of the clamping plate 307 under the elastic force of the spring 309, effectively enhance the stability of the connection. These features ensure that the steel beam 2 will not shake or shift after connection, guaranteeing the overall stability of the connection. The stability of the steel structure; the stable connection characteristics of the quick connection device 3 reduce safety hazards during construction; due to the simple and reliable connection process, operators can more easily complete the connection work, reducing the risk of safety accidents caused by unstable connections; the quick connection device 3 makes it easier to disassemble and reinstall the steel beam 2 when maintenance or replacement is needed; this disassembly not only facilitates adjustments during construction, but also provides convenience for subsequent maintenance and upgrades; it can adapt to the connection needs of steel beams 2 of different sizes and shapes; this adaptability makes the quick connection device 3 have a wider range of application prospects in steel structure engineering.
