Description

Technical Field

[0001] This utility model belongs to the field of building steel structure technology, and in particular relates to a connection node structure for prefabricated buildings. Background Technology

[0002] The connection node structure in prefabricated buildings refers to the part in prefabricated buildings where prefabricated components are assembled through specially designed connection nodes. The connection node structure is not only responsible for effectively connecting the various components together, but also undertakes important functions such as load transfer, ensuring building stability and seismic resistance. The design of the connection node needs to consider the mechanical properties between different components, the compatibility of materials, and the convenience of construction.

[0003] Existing prefabricated building connection node structures still have some problems in use. For example, in the process of connecting columns and beams, welding is usually required for fixing. This not only significantly reduces the construction efficiency of prefabricated steel structure buildings, but also increases the safety risks of welding operations because the connection nodes are mostly located at high places. In addition, existing connection nodes are insufficient in terms of seismic performance and adaptability, making it difficult to meet diverse building needs and limiting their widespread application.

[0004] To address these issues, we provide a prefabricated building connection node structure. Utility Model Content

[0025] Specifically: After the connecting sleeve 2 is fitted onto the surface of the steel column 1, it can move in the parallel direction of the steel column 1 to connect the crossbeam 5 at the required position. The distance of the inner cavity of the locking block 3 is close to the surface of the web plate at the center of the crossbeam 5 so that it can be fixed to the surface of the connecting sleeve 2 by fastening bolts 4. The first bolt 6 can install the right angle bracket 7, and the second bolt 8 can connect the right angle bracket 7 to the crossbeam 5. The transverse structure of the top and bottom areas of the crossbeam 5 is the beam flange, and the vertical structure at the center is the beam web plate. The fastening bolt 4 has a nut threaded on its surface to fasten the crossbeam 5.

[0026] Example 2

[0027] Please see Figures 1-5Based on Example 1, support blocks 9 are fixedly connected to all four sides of the surface of the connecting sleeve 2. The top of the support block 9 is slidably connected to the bottom of the crossbeam 5. A tripod 10 is fixedly connected to the bottom of the support block 9. The tripod 10 is used to improve the stability of the support block 9. The inner cavity of the connecting sleeve 2 is threaded with mounting bolts 11. One end of the mounting bolt 11 extends into the inner cavity of the steel column 1. A damper 12 is fixedly connected to one side of the bottom of the right-angle bracket 7. A gasket 13 is fixedly connected to the free end of the damper 12. The bottom of the gasket 13 contacts one side of the top of the crossbeam 5. Buffer pads 14 are fixedly connected to both sides of the inner cavity of the locking block 3. The buffer pads 14 are made of rubber. The inner cavity of the connecting sleeve 2 has an insertion port 15. The surface of the steel column 1 is slidably connected to the inner cavity of the insertion port 15. The locking block 3 is used to fix the center of the crossbeam 5 and is further reinforced by fastening bolts 4.

[0028] Specifically: the inner cavity of the support block 9 has a locking groove to lock the bottom flange of the crossbeam 5, ensuring the stability of the bottom of the crossbeam 5; the triangular bracket 10 can improve the stability of the support block 9, further improving the stability of the crossbeam 5; the mounting bolt 11 can install the connecting sleeve 2 on the surface of the steel column 1; the gasket 13 at the free end of the damper 12 contacts the top flange of the crossbeam 5 to improve the seismic performance of the crossbeam 5; the buffer pad 14 can improve the seismic performance of the web of the crossbeam 5 without affecting the installation; and a detachable right-angle bracket 7 is provided, which can be flexibly used when installing the corresponding crossbeam 5 on the surface of the steel column 1 according to actual needs, avoiding the right-angle bracket 7 being idle in unnecessary situations, thereby reducing its redundancy and improving resource utilization efficiency.

After the connecting sleeve 2 moves to the position of the crossbeam 5, the connecting sleeve 2 is fixed to the surface of the steel column 1 by screwing in the installation bolt 11. Then, through the design of the inner cavity of the locking block 3, the web of the crossbeam 5 can be locked and fixed, and further reinforced by the fastening bolt 4 to ensure the stability of the connection. The support block 9 provides reliable support for the bottom wing plate of the crossbeam 5, enhancing the load-bearing capacity of the overall structure and enabling the locking block 3 to be fixedly connected to the web of the crossbeam 5.

[0030] With support at the bottom of the crossbeam 5 and the web of the beam fixed, the right-angle bracket 7 is installed on one side of the surface of the connecting sleeve 2 by the first bolt 6. After the right-angle bracket 7 is installed, the second bolt 8 is screwed in to connect the right-angle bracket 7 to the top of the crossbeam 5, thereby connecting the crossbeam 5 to the steel column 1. At this time, the gasket 13 at the free end of the damper 12 at the bottom of the right-angle bracket 7 will contact the top of the crossbeam 5 to improve the seismic resistance of the crossbeam 5 flange. The buffer pad 14 in the inner cavity of the locking block 3 can improve the seismic resistance of the crossbeam 5 web. Thus, the installation work can be completed.
