[0026] 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.

[0027] Reference Figure 1-4 This utility model provides a precast beam with a rapid assembly node connection structure, including a precast column 1 and a precast beam 3. A rigid precast component 2 is provided in the middle of the precast column 1. One end of the precast beam 3 is fixedly connected to the rigid precast component 2. Positioning rods 4 are symmetrically arranged on both sides of the precast column 1 near the top of the rigid precast component 2. Positioning mechanisms are symmetrically arranged on both sides of the positioning rods 4. A concrete covering block 5 is provided on one end of the precast beam 3 near the rigid precast component 2. The rigid precast component 2 includes a first fixing frame 21 and a second fixing frame 22 symmetrically arranged. A fixing mechanism is provided on the outer contour of the rigid precast component 2. The positioning mechanism includes a sliding rod 6 fixedly connected to the top of the first fixing frame 21 and the second fixing frame 22. A sliding groove 7 is provided at the bottom of the positioning rod 4 for the sliding rod 6 to engage. Positioning components 8 are provided on both sides of the top of the positioning rod 4.

[0028] First, the first fixed frame 21 and the second fixed frame 22 are assembled on the precast column 1 using a positioning mechanism, thereby assembling the first fixed frame 21 and the second fixed frame 22 into a rigid precast component 2. Then, the first fixed frame 21 and the second fixed frame 22 are positioned using positioning parts 8 provided on both sides of the positioning rod 4. After positioning, the precast column 1 and the rigid precast component 2 are effectively fixed using a fixing mechanism on the rigid precast component 2. After fixing, the precast beam 3 is screwed to the rigid precast component 2. After screwing, the concrete covering block 5 is placed at the connection between the rigid precast component 2 and the precast beam 3.

[0029] The positioning component 8 includes an adjustment groove 9 that runs through both sides of the positioning rod 4. An adjustment plate 10 is slidably connected to the inner wall of the adjustment groove 9. A toggle block 11 is fixedly connected to the top of the adjustment plate 10. A limiting groove 13 runs through the outer contour of the sliding rod 6 and the inner wall of the sliding groove 7 near the limiting plate 12. A limiting plate 12 that engages with the limiting groove 13 is fixedly connected to the bottom of the toggle block 11. A rectangular magnetic ring 14 is provided on the inner wall of the adjustment groove 9 near the top. Fastening bolts are provided at the four corners of the top of the rectangular magnetic ring 14 and are screwed to the positioning rod 4 through the fastening bolts. The inner wall of the rectangular magnetic ring 14 is slidably connected to the adjustment plate 10. The main view shape of the sliding rod 6 is trapezoidal. The main view shape of the sliding groove 7 is the same as that of the sliding rod 6.

[0030] The operator pulls the actuating block 11 upwards, causing the adjusting plate 10 at the bottom of the actuating block 11 to move upwards within the adjusting groove 9. Subsequently, the upward-moving adjusting plate 10 causes the limiting plate 12 to move upwards, so that the limiting plate 12 moves out of the limiting groove 13 opened on the sliding groove 7. Then, the limiting plate 12 is magnetically treated with the rectangular magnetic ring 14. At this time, the operator slides the sliding rods 6 on the first fixed frame 21 and the second fixed frame 22 into the sliding groove 7 opened at the bottom of the positioning rod 4, so that the limiting groove 13 on the sliding rod 6 is aligned with the limiting groove 13 on the sliding groove 7. Then, the operator moves the actuating block 11 downwards, causing the limiting plate 12 at the bottom of the adjusting plate 10 to move downwards within the adjusting groove 9, so that the limiting plate 12 is engaged into the limiting groove 13. At this time, the operator has completed the assembly and positioning process of the precast column 1, the first fixed frame 21 and the second fixed frame 22.

[0031] The rigid precast component 2 also includes a connecting plate 23 symmetrically arranged on the first fixed frame 21 and the second fixed frame 22. The connecting plate 23 has a through hole. The surfaces of the first fixed frame 21 and the second fixed frame 22 have through holes 24. The middle part of the precast column 1 has a fixing bolt 25 that matches the through hole 24. The inner wall of the through hole 24 has a groove 26. The inner wall of the fixing bolt 25 is screwed to the groove 26.

[0032] After the first fixed frame 21 and the second fixed frame 22 are assembled, the through holes 24 on the first fixed frame 21 and the second fixed frame 22 are aligned with the grooves 26 opened on the precast column 1. After alignment, the fixing bolts 25 are inserted into the through holes 24 and bolted to the grooves 26 on the precast column 1, so that the first fixed frame 21 and the second fixed frame 22 are fixed to the precast column 1 after assembly.

[0033] Working principle: The operator pulls the actuating block 11 upward, causing the adjusting plate 10 at the bottom of the actuating block 11 to move upward in the adjusting groove 9. Then, the upward-moving adjusting plate 10 causes the limiting plate 12 to move upward, so that the limiting plate 12 moves out of the limiting groove 13 opened on the sliding groove 7. Then, the limiting plate 12 is magnetically treated with the rectangular magnetic ring 14. At this time, the operator slides the sliding rods 6 on the first fixed frame 21 and the second fixed frame 22 into the sliding groove 7 opened at the bottom of the positioning rod 4, so that the limiting groove 13 on the sliding rod 6 is aligned with the limiting groove 13 on the sliding groove 7. Then, the operator moves the actuating block 11 downward, causing the limiting plate 12 at the bottom of the adjusting plate 10 to move downward in the adjusting groove 9, so that the limiting plate 12 is engaged in the limiting groove 13. At this time, the operator completes the assembly and positioning of the precast column 1, the first fixed frame 21 and the second fixed frame 22.

[0034] After the first fixed frame 21 and the second fixed frame 22 are assembled, the through holes 24 on the first fixed frame 21 and the second fixed frame 22 are aligned with the grooves 26 opened on the precast column 1. After alignment, the fixing bolts 25 are inserted into the through holes 24 and bolted to the grooves 26 on the precast column 1, so that the first fixed frame 21 and the second fixed frame 22 are fixed to the precast column 1 after assembly. After fixing, the connecting plate on the precast beam 3 is connected to the connecting plate 23 on the rigid precast component 2. After the rigid precast component 2 and the precast beam 3 are installed, the concrete covering block 5 is set at the connection between the rigid precast component 2 and the precast beam 3.
