Specific embodiments
[0022] Please refer to Figures 1-6, the utility model provides a precast concrete beam-column connection structure for buildings, including a precast concrete beam column 1. On one side of the precast concrete beam column 1, there is a first precast concrete beam cross-column 2. At one end of the precast concrete beam column 1, there is a second precast concrete beam cross-column 3. Two first slots 4 are penetrated through the surfaces on the left and right sides of the precast concrete beam column 1. Two second slots 6 are penetrated through the surfaces at the front and rear ends of the precast concrete beam column 1. The first slot 4 is communicated with the second slot 6 at the adjacent position. On the surface of one end of the first precast concrete beam cross-column 2, two first sockets 7 are fixed. A positioning port 8 is penetrated through the surface of the first socket 7. On the surface of one side of the first precast concrete beam cross-column 2, two second sockets 9 are fixed. The first socket 7 is slidably connected with the second slot 6. The second socket 9 is slidably connected with the first slot 4 and the positioning port 8. On the surface of one side of the second socket 9, a fixing block 10 is fixed. A first threaded cylinder 11 is penetrated and threadedly connected at the middle position of the fixing block 10. At the middle position of one of the first threaded cylinders 11, a threaded column 12 is threadedly connected. The threaded column 12 is slidably connected with the other first threaded cylinder 11. On the surface of one end of the first precast concrete beam cross-column 2 and on the surface of one side of the second precast concrete beam cross-column 3, a support plate 24 is attached. At the middle position of the two support plates 24, a reinforcement plate 26 is arranged. By inserting the first socket 7 into the interior of the second slot 6 at the adjacent position, the second socket 9 into the interior of the first slot 4 and the positioning port 8 at the adjacent position, and by extending the threaded column 12 into the interior of the first threaded cylinder 11 at the adjacent position and installing the reinforcement plate 26 at the middle position of the two support plates 24, the first precast concrete beam cross-column 2 and the second precast concrete beam cross-column 3 can be limited and reinforced, so that it is convenient for the user to quickly assemble the precast concrete beam column 1, the first precast concrete beam cross-column 2 and the second precast concrete beam cross-column 3, thus shortening the time during connection and installation, and improving the connection and installation efficiency of the device.
[0023] Further, as Figure 1 , Figure 2 and Figure 3As shown, it is worth specifically explaining that two support holes 27 are penetrated and opened on the side surfaces of the first precast concrete beam cross-column 2 and the second precast concrete beam cross-column 3. An insertion shaft 25 is inserted into the interior of the support hole 27. The surface of the insertion shaft 25 near the surface of the adjacent position support plate 24 is fixed to the surface of the adjacent position support plate 24. A slot 28 is opened on the surface of the support plate 24. An insertion plate 5 is inserted into the interior of the slot 28. One side of the insertion plate 5 is fixed to the surface of the adjacent position reinforcement plate 26. Two second bolts 29 are threadedly connected to the position of the support plate 24 near the adjacent position slot 28. The second bolts 29 are slidably connected to the adjacent position insertion plate 5. By inserting the two insertion shafts 25 fixed to the surface of the support plate 24 into the interior of the adjacent position support holes 27, the second fixing block second fixing seat 23 can be connected to the second precast concrete beam cross-column 3 and the second fixing block second fixing seat 23 can be connected to the first precast concrete beam cross-column 2. The reinforcement plate 26 is inserted into the middle position of the two support plates 24 through the slot 28 and the insertion plate 5, and the second bolts 29 can limit the insertion plate 5, thereby improving the connection stability between the precast concrete beam column 1 and the first precast concrete beam cross-column 2 and between the precast concrete beam column 1 and the second precast concrete beam cross-column 3.
[0024] Further, as Figure 5 shown, it is worth specifically explaining that two first fixing seats 14 are fixed at the positions of the precast concrete beam column 1 at the top of the second groove 6 and the top of the first groove 4. A movable shaft 16 is rotatably connected at the middle position between the two adjacent first fixing seats 14. A rotating cylinder 15 is fixedly sleeved on the outer peripheral surface of the movable shaft 16. A second threaded cylinder 17 is threadedly connected at the middle position of the rotating cylinder 15. The angle of the rotating cylinder 15 can be adjusted through the movable shaft 16, and the total length between the rotating cylinder 15 and the second threaded cylinder 17 can be adjusted by the cooperation of the threaded structure between the rotating cylinder 15 and the second threaded cylinder 17 by rotating the second threaded cylinder 17.
[0025] Further, as Figure 5 and Figure 6As shown, it is worth specifically explaining that a movable rod 19 is slidably inserted at the middle position of the second threaded cylinder 17. One end of the movable rod 19 is fixed with a spring 18, and one end of the spring 18 is fixed to one end of the inner wall of the second threaded cylinder 17. One end of the movable rod 19 is fixed with a connecting shaft 20. A first bolt 22 is inserted through the middle position of the connecting shaft 20. Two second fixing seats 23 are fixed on the top surfaces of the first precast concrete beam cross-column 2 and the second precast concrete beam cross-column 3. Jacks 21 are formed on the surfaces of the two second fixing seats 23. One end of the first bolt 22 is threadedly connected to one of the second fixing seats 23. The other end of the first bolt 22 extends into the adjacent jack 21. Due to the arrangement of the spring 18, the movable rod 19 can abut against the spring 18 to cause it to deform. By rotating the first bolt 22, it extends horizontally under the cooperation of the threaded structure with the adjacent second fixing seat 23, so that the first bolt 22 can pass through the connecting shaft 20 and extend into the adjacent jack 21, thereby being able to limit the connecting shaft 20. Thus, when the first precast concrete beam cross-column 2 and the second precast concrete beam cross-column 3 shake vertically under an external force, the movable rod 19 can be driven to abut against the adjacent spring 18 to cause it to deform, thereby improving the stability of the first precast concrete beam cross-column 2 and the second precast concrete beam cross-column 3.
[0026] The present solution has the following working process: During actual use, insert the first socket 7 on the surface of one end of the second precast concrete beam cross-column 3 into the interior of the second slot 6 at an adjacent position. Then, insert the second socket 9 on the surface of one side of the first precast concrete beam cross-column 2 into the interior of the first slot 4 and pass through the interior of the positioning port 8. Subsequently, under the cooperation of the threaded structure between the first threaded cylinder 11 and the fixed block 10, the first threaded cylinder 11 can extend in the vertical direction, so that the threaded column 12 fixed to the surface of one of the first threaded cylinders 11 is inserted into the interior of the other first threaded cylinder 11, thereby being able to limit the second socket 9 and prevent the second socket 9 from detaching from the interior of the first slot 4 at an adjacent position, and thus being able to fix the connection between the precast concrete beam column 1 and the first precast concrete beam cross-column 2, as well as between the precast concrete beam column 1 and the second precast concrete beam cross-column 3. Subsequently, insert the reinforcement plate 26 into the middle position between the two support plates 24 through the slot 28 and the insertion plate 5, and the second bolt 29 can limit the insertion plate 5, thereby being able to improve the stability of the connection between the precast concrete beam column 1 and the first precast concrete beam cross-column 2, as well as between the precast concrete beam column 1 and the second precast concrete beam cross-column 3. Subsequently, the angle of the rotating cylinder 15 can be adjusted through the movable shaft 16, and by rotating the second threaded cylinder 17, under the cooperation of the threaded structure between the second threaded cylinder 17 and the rotating cylinder 15, the total length between the rotating cylinder 15 and the second threaded cylinder 17 can be adjusted, so that the connecting shaft 20 can extend to the middle position between two adjacent second fixed seats 23. Subsequently, rotate the first bolt 22 so that it extends horizontally under the cooperation of the threaded structure, so that the first bolt 22 can pass through the connecting shaft 20 and extend into the interior of the adjacent jack 21. Thus, under an external force, the first precast concrete beam cross-column 2 and the second precast concrete beam cross-column 3 can shake in the vertical direction, which can drive the movable rod 19 to abut against the adjacent spring 18 and cause it to deform, thereby being able to improve the stability of the first precast concrete beam cross-column 2 and the second precast concrete beam cross-column 3.
[0027] According to the above working process, it can be seen that: between the precast concrete beam column 1, the first precast concrete beam cross-column 2 and the second precast concrete beam cross-column 3, the first socket 7 is inserted into the interior of the second slot 6 at the adjacent position, and the second socket 9 is inserted into the interior of the first slot 4 and the positioning port 8 at the adjacent position. By extending the threaded column 12 into the interior of the first threaded cylinder 11 at the adjacent position and installing the reinforcing plate 26 at the middle position between the two support plates 24, the first precast concrete beam cross-column 2 and the second precast concrete beam cross-column 3 can be limited and reinforced, facilitating the user to quickly assemble the precast concrete beam column 1, the first precast concrete beam cross-column 2 and the second precast concrete beam cross-column 3 with each other, shortening the time for connection and installation, improving the efficiency of connection and installation of the device, and thus enhancing the practicality of the device. By rotating the rotating cylinder 15, its angle can be adjusted so that the first precast concrete beam cross-column 2 can extend to the middle position between the two connecting shafts 20 at the adjacent position, and the connecting shaft 20 is limited by the first bolt 22. Thus, during use, under the action of the resilience of the spring 18, the precast concrete beam column 1 and the first precast concrete beam cross-column 2 and between the precast concrete beam column 1 and the second precast concrete beam cross-column 3 can play an anti-deformation role, improving the compressive performance of the device.
[0028] Furthermore, as Figure 2 shown, it is specifically worth noting that two positioning caps 13 are threadedly connected to the outer peripheral surface of the threaded column 12. The mutually remote ends of the positioning caps 13 are in contact with the surface of the first threaded cylinder 11 at the adjacent position. By rotating the positioning caps 13, they extend in the vertical direction under the cooperation of the threaded structure with the threaded column 12, so that the positioning caps 13 can abut against the surface of the first threaded cylinder 11 at the adjacent position, improving the stability of the connection between the two first threaded cylinders 11, and further enhancing the stability of the connection between the precast concrete beam column 1 and the first precast concrete beam cross-column 2 and between the precast concrete beam column 1 and the second precast concrete beam cross-column 3.
[0029] In summary: By inserting the first socket 7 into the interior of the second slot 6 at the adjacent position between the precast concrete beam column 1, the first precast concrete beam cross-column 2 and the second precast concrete beam cross-column 3, and inserting the second socket 9 into the interior of the first slot 4 and the positioning port 8 at the adjacent position, and by extending the threaded column 12 into the interior of the first threaded cylinder 11 at the adjacent position and installing the reinforcing plate 26 at the middle position between the two support plates 24, the first precast concrete beam cross-column 2 and the second precast concrete beam cross-column 3 can be limited and reinforced, facilitating the user to quickly assemble the precast concrete beam column 1, the first precast concrete beam cross-column 2 and the second precast concrete beam cross-column 3 with each other, shortening the time for connection and installation, improving the efficiency of the device during connection and installation, and enhancing the practicality of the device. By rotating the rotating cylinder 15, its angle can be adjusted so that the first precast concrete beam cross-column 2 can extend to the middle position between the two connecting shafts 20 at the adjacent position and the connecting shaft 20 is limited by the first bolt 22. Thus, during use, under the action of the resilience of the spring 18, an anti-deformation effect can be achieved between the precast concrete beam column 1 and the first precast concrete beam cross-column 2 and between the precast concrete beam column 1 and the second precast concrete beam cross-column 3, improving the compressive performance of the device. By rotating the positioning cap 13, it extends in the vertical direction under the cooperation of the threaded structure with the threaded column 12, so that the positioning cap 13 can abut against the surface of the first threaded cylinder 11 at the adjacent position, improving the stability of the connection between the two first threaded cylinders 11 and further enhancing the stability of the connection between the precast concrete beam column 1 and the first precast concrete beam cross-column 2 and between the precast concrete beam column 1 and the second precast concrete beam cross-column 3.
