[0001] The utility model relates to the technical field of node connection, in particular to an assembled building node connection structure. Background Art

[0002] In the field of prefabricated buildings, joint connections are critical for ensuring the overall stability and safety of the structure. However, traditional joint connection methods in prefabricated buildings often suffer from low construction efficiency and insufficient connection reliability. Traditional connection methods often require complex installation steps and a large number of fasteners, which not only increases construction difficulty and time costs but can also cause stress concentration at the connection points, affecting the overall performance of the structure. Furthermore, traditional connection methods often require the disassembly of numerous other components for maintenance, increasing the complexity and cost of maintenance.

[0003] Furthermore, with the continuous development of prefabricated building technology and the expansion of its application areas, the requirements for prefabricated building node connection structures are becoming increasingly stringent. Traditional connection methods can no longer meet the efficiency, reliability, and ease of maintenance required of modern prefabricated buildings. In particular, in large-scale public buildings and residential industrialization, the construction efficiency, connection strength, stability, and maintenance ease of prefabricated building node connection structures are being placed on a higher level. To this end, we have developed a prefabricated building node connection structure. Utility Model Content

[0004] In order to solve the above problems, the present invention proposes an assembled building node connection structure to more accurately solve the problems raised in the above background technology.

[0005] The utility model is achieved through the following technical solutions:

[0006] The utility model proposes an assembled building node connection structure, comprising an assembled building vertical beam, an assembled building horizontal beam, and an L-shaped connecting plate installed at the node between the two. A quick disassembly mechanism is connected between the assembled building vertical beam and the L-shaped connecting plate; a fixing structure is connected between the assembled building horizontal beam and the L-shaped connecting plate; and a stabilizing component is connected between the assembled building vertical beam and the L-shaped connecting plate.

[0008] Furthermore, the reset component includes a strip-shaped placement groove opened on the inner side wall of the storage groove, a vertical fixing rod is fixedly connected between the two end walls of the strip-shaped placement groove, a spring is provided on the outer periphery of the vertical fixing rod, and a movable sleeve block is slidably sleeved on the outer periphery of the vertical fixing rod.

[0009] Furthermore, the fixing structure includes a threaded hole opened on the assembled building beam and a fixing screw threadedly connected to the L-shaped connecting plate, and the threaded section of the fixing screw passes through the L-shaped connecting plate and is threadedly connected to the inner wall of the threaded hole.

[0010] Furthermore, the stabilizing component includes a plug-in hole opened on the side of the vertical beam of the prefabricated building and a stabilizing plug-in rod fixedly connected to the periphery of the L-shaped connecting plate, and the stabilizing plug-in rod is inserted into the inner wall of the plug-in hole.

[0011] Furthermore, the upper end of the spring is fixedly connected to the lower end surface of the movable sleeve block, and the lower end of the spring is fixedly connected to the end wall of the strip-shaped placement groove.

[0021] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0022] Example

[0023] like Figure 1-Figure 4 As shown, an embodiment of the present invention proposes an assembled building node connection structure, which is mainly composed of an assembled building vertical beam 1, an assembled building horizontal beam 2, and an L-shaped connecting plate 3. A quick disassembly mechanism is designed at the connection between the vertical beam 1 and the L-shaped connecting plate 3 to facilitate quick installation and disassembly. The quick disassembly mechanism consists of a rectangular through-slot 4 provided on the side of the vertical beam 1 and a plug-in block 5 fixed to the periphery of the L-shaped connecting plate 3. A storage groove 6 is provided at the upper end of the plug-in block 5. An arc-shaped limit block 11 is slidably inserted into the storage groove 6 to prevent the plug-in block 5 from being dislodged after the plug-in block 5 is inserted into the rectangular through-slot 4. The storage groove 6 and the arc-shaped limit block 11 are connected by a reset component to ensure that the arc-shaped limit block 11 can automatically pop out when needed. At the same time, the horizontal beam 2 and the L-shaped connecting plate 3 are connected by a fixed structure to ensure the stability of the connection. In addition, a stabilizing component is provided between the vertical beam 1 and the L-shaped connecting plate 3 to further enhance the stability of the connection.

[0024] Furthermore, the design of the reset component includes a strip-shaped placement groove 7 formed on the inner side wall of the receiving groove 6, a vertical fixing rod 8 fixedly connected to the strip-shaped placement groove 7, and a spring 9 sleeved around the vertical fixing rod 8. One end of the spring 9 is fixedly connected to the end wall of the strip-shaped placement groove 7, and the other end is fixedly connected to a movable sleeve 10 that is slidably sleeved around the vertical fixing rod 8. The movable sleeve 10 slides within the strip-shaped placement groove 7, and the opposing surfaces of the two movable sleeves 10 are fixedly connected to the two sides of the arc-shaped limit block 11. When the plug-in block 5 is inserted into the rectangular through-slot 4, the arc-shaped limit block 11 is compressed into the receiving groove 6, and the movable sleeve 10 moves accordingly and compresses the spring 9. When the plug-in block 5 reaches the predetermined position, the elastic force of the spring 9 pushes the movable sleeve 10, which in turn drives the arc-shaped limit block 11 to pop out, preventing the plug-in block 5 from falling out. The design of the reset component ensures that the arc-shaped limit block 11 can automatically pop out after the plug-in block 5 is inserted, effectively preventing the plug-in block 5 from accidentally falling out.

[0025] Furthermore, the design of the fixing structure includes threaded holes 12 in the prefabricated building beam 2 and through-holes corresponding to threaded holes 12 in the L-shaped connecting plate 3. Tightening screws 13, which are threaded into the L-shaped connecting plate 3, securely connect the L-shaped connecting plate 3 to the beam 2. The threaded section of the tightening screw 13 penetrates the L-shaped connecting plate 3 and is threaded into the inner wall of the threaded hole 12, ensuring a secure connection. The design of the fixing structure ensures a stable connection between the L-shaped connecting plate 3 and the beam 2, improving the reliability of the joint connection.

[0026] Furthermore, the design of the stabilizing assembly includes a socket 14 formed on the side of the prefabricated building vertical beam 1, and a stabilizing rod 15 fixedly connected to the periphery of the L-shaped connecting plate 3. The shape and size of the stabilizing rod 15 match the socket 14, ensuring that the stabilizing rod 15 can be smoothly inserted into the socket 14. After the L-shaped connecting plate 3 and the vertical beam 1 are connected via the quick-release mechanism, the stabilizing rod 15 is inserted into the socket 14, further enhancing the stability of the connection. The design of the stabilizing assembly improves the stability of the node connection and ensures the safety of the prefabricated building during use.

[0027] Furthermore, the upper end of spring 9 is fixedly connected to the lower surface of movable sleeve 10, while the lower end is fixedly connected to the end wall of strip-shaped receiving groove 7. This connection ensures that spring 9 generates sufficient elastic force when compressed to push movable sleeve 10 and arc-shaped stopper 11 back into position. Furthermore, the elastic force and stability of spring 9 also ensure the reliability and durability of the quick-disconnect mechanism. This connection ensures that the arc-shaped stopper 11 in the quick-disconnect mechanism automatically pops out and resets, improving the reliability and stability of the connection structure.

[0028] Furthermore, the movable sleeve 10 is slidably connected to the inner wall of the strip-shaped mounting groove 7, ensuring that the movable sleeve 10 can move smoothly along the vertical support rod 8 when subjected to external forces. At the same time, the opposing surfaces of the two movable sleeves 10 are fixedly connected to the two sides of the arc-shaped limit block 11, ensuring the stability and accuracy of the arc-shaped limit block 11 during movement. This connection method not only improves the reliability of the rapid disassembly and assembly mechanism, but also simplifies the operation steps and improves construction efficiency. The sliding connection of the movable sleeve 10 and the fixed connection with the arc-shaped limit block 11 ensure the smooth movement and resetting of the arc-shaped limit block 11 in the rapid disassembly and assembly mechanism, improving the stability of the connection structure and construction efficiency.
