Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated building technology, and in particular to beam-column joint connectors for prefabricated buildings. Background Technology
[0002] Prefabricated building beam-column joint connectors are standardized key components made of materials such as steel plates and bolts. They are used for the rapid on-site connection of beams and columns in prefabricated concrete or steel structures, and have the advantages of improving construction efficiency, ensuring structural reliability, reducing construction difficulty, promoting green construction, and adapting to diverse designs.
[0003] Prefabricated building beam-column joint connectors are generally composed of steel plates, bolts, connecting plates, etc. Prefabricated building beam-column joint connectors use standardized mechanical connection structures (such as bolts and sleeves) to assemble prefabricated beams and columns into a whole on site. By clearly defining the force transmission path, stiffness matching, and deformation coordination design, load transfer and structural safety are achieved.
[0004] The existing prefabricated building beam-column joint connectors cannot achieve rapid installation of steel, leading to low construction efficiency. More time is spent on-site for complex operations such as bolt tightening and welding, delaying process connections and extending the construction period. In addition, the increased labor input and reliance on skilled workers, as well as the increased safety risks associated with working at heights and complex operations, affect the overall integrity and reliability of the structure due to the extended temporary support time for components. The increased on-site wet work and energy consumption also contradict the goals of green building and cannot be matched with the logic of prefabricated component factory production, limiting the improvement of the degree of building industrialization and making it difficult to fully realize the advantages of prefabricated buildings. Therefore, prefabricated building beam-column joint connectors are proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a prefabricated building beam-column joint connector, which aims to improve the problem that the existing technology cannot achieve rapid installation of steel.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A prefabricated building beam-column joint connector includes a beam and a column. A fixed frame is fixedly connected to the outer side of the beam and column. Connecting blocks are fixedly connected to all four sides of the fixed frame. H-beams are slidably connected to the outer side of the connecting blocks. Bolts are slidably connected to the outer side of the H-beams. Vibration damping components are slidably connected to the outer side of the H-beams.
[0008] As a further description of the above technical solution:
[0009] The shock absorption assembly includes a rotating block, a rotating plate rotatably connected inside the rotating block, a spring fixedly connected to the top of the rotating plate, and a damper fixedly connected to the top of the rotating plate.
[0010] As a further description of the above technical solution:
[0011] The outer side of the H-beam is slidably connected to a connecting plate, the inner side of the connecting plate is slidably connected to the outer side of the connecting block, and the inner side of the connecting plate is rotatably connected to multiple bolts.
[0012] As a further description of the above technical solution:
[0013] Two of the bolts are rotatably connected inside the H-beam, and the other two bolts are rotatably connected outside the connecting block.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, the installation effect of the H-beam is achieved by using a fixed frame with connecting blocks, connecting blocks with H-beams, H-beams with connecting plates, and connecting plates with bolts. Energy is dissipated by the synergistic action of dampers and springs. It has the advantages of convenient assembly, easy maintenance, wide applicability, and optimized life cycle cost.
[0016] 2. In this utility model, the rotating block cooperates with the rotating plate, and the rotating plate cooperates with the damper and the spring to achieve the vibration reduction effect on the H-beam. With reliable load-bearing capacity, clear force transmission path, standardized prefabrication advantages, convenient construction and assembly, and economic cost control, it has become the preferred foundation connection method for static load structures, low-intensity fortification areas, and projects that require later renovation.

[0023] 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.
[0024] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model provides a prefabricated building beam-column joint connector, including a beam-column 1. A fixed frame 2 is fixedly connected to the outside of the beam-column 1. The fixed frame 2 provides a stable base for the connection between the beam-column 1 and external components. Connecting blocks 3 are fixedly connected around the beam-column 1. The connecting blocks 3 serve as transition components to facilitate the installation and positioning of H-beams 5. H-beams 5 are slidably connected to the outside of the connecting blocks 3. The H-beams 5 can slide along the outside of the connecting blocks 3 to achieve preliminary alignment to meet installation requirements.
[0025] A connecting plate 4 is slidably connected to the outside of the H-beam 5. The connecting plate 4 can slide on the outside of the H-beam 5 to ensure precise alignment with the holes of the connecting block 3. Multiple bolts 6 are rotatably connected inside the connecting plate 4. The bolts 6 pass through the holes of the connecting plate 4, the H-beam 5 and the connecting block 3. A reliable mechanical connection is formed by tightening. The inside of the connecting plate 4 is slidably connected to the outside of the connecting block 3, so that the connecting plate 4 can fit against the surface of the connecting block 3 and ensure that the bolts 6 are evenly stressed. The bolts 6 are slidably connected to the outside of the H-beam 5. The bolts 6 can slide on the outside of the H-beam 5 to adjust their insertion position and improve installation tolerance.
[0026] The outer sides of the other two bolts 6 are rotatably connected to the inside of the connecting block 3. These two bolts 6 fix the connecting block 3 to the connecting plate 4, enhancing the rigidity of the node connection. Two of the bolts 6 are rotatably connected to the inside of the H-beam 5. These two bolts 6 make the H-beam 5 and the connecting plate 4 tightly connected, ensuring effective load transfer. The outer side of the H-beam 5 is slidably connected to a damping component, which can absorb external vibration energy and reduce the structural vibration response.
[0027] Reference Figures 1 to 3The damping component includes a rotating block 7, which is installed on the outside of the H-beam 5 to provide a rotation fulcrum for the damping component. A rotating plate 8 is rotatably connected inside the rotating block 7. The rotating plate 8 can rotate around the rotating block 7 to adapt to the angle changes during structural deformation. A spring 10 is fixedly connected to the top of the rotating plate 8. The spring 10 absorbs vibration energy through elastic deformation to reduce structural displacement. A damper 9 is fixedly connected to the top of the rotating plate 8. The damper 9 suppresses the vibration amplitude by consuming energy and works in conjunction with the spring 10 to improve the damping effect.
[0028] Working principle: When the worker needs to install the H-beam 5, the hole opened inside the H-beam 5 can be slid to the outside of the connecting block 3. Then the connecting plate 4 is placed inside the hole opened inside the H-beam 5 and the connecting block 3, and then the bolts 6 are used to connect them.
[0029] After the H-beam 5 is installed, the rotating block 7 can be installed and fixed to the outside of the H-beam 5. Then, the other end can be fixed to the outside of the beam and column 1. At this time, the spring 10 and damper 9 on the top of the rotating plate 8 can reduce the shock to the outside.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
