[0022] like Figure 1-4 As shown, a high-low grade concrete interception device for beam-column joints includes a splicing plate and a round rod 3, two of the splicing plates are spliced ​​together, and the splicing plates are embedded between the main reinforcements 5 of the beam, a protrusion is provided on the side wall of one of the splicing plates, and a groove is provided on the side wall of the other adjacent splicing plate, the groove and the protrusion match, a long hole is opened on the splicing plate and the long hole is perpendicular to the splicing surface, threads are provided at both ends of the round rod 3, the round rod 3 passes through the long hole and is locked in place by a nut 4, temporary fixing steel bars 9 are provided on both sides of the splicing plate, and the temporary fixing steel bars 9 are bound and fixed to the main reinforcements 5 of the beam.

[0023] The long hole is horizontally arranged on the splicing plate, and the long hole passes through the groove and the protrusion. Specifically, the round rod 3 passes through the groove and the protrusion and is fixed by the nut 4, so that the overall structure is more stable and the effect of blocking concrete is stronger.

[0024] One embodiment, such as Figure 1 As shown, the splicing plate includes a first splicing plate 1 and a second splicing plate 2, a plurality of square grooves 7 are arranged on one side wall of the first splicing plate 1, a plurality of arc grooves 6 are arranged on the other side wall of the first splicing plate 1, a plurality of square protrusions 8 are arranged on one side wall of the second splicing plate 2, a plurality of arc grooves 6 are arranged on one side wall of the second splicing plate 2, the first splicing plate 1 and the second splicing plate 2 are snap-fitted together, the arc grooves 6 are respectively snap-fitted with the main reinforcement 5 of the beam, and the square grooves 7 match the square protrusions 8.

[0025] During implementation, first, the first splicing plate 1 and the second splicing plate 2 are spliced ​​together through the square grooves and the square protrusions. Then, multiple groups of splicing plates are extended from the horizontal gaps of the main beam reinforcement 5 into the interior of the main beam reinforcement, and the positions of the splicing plates are adjusted so that the arc-shaped grooves of the multiple groups of splicing plates are engaged with the main beam reinforcement 5. Then, the multiple splicing plates are connected together by passing the horizontal long holes on the splicing plates through the round rods 3. The structure is more stable and is suitable for situations where the horizontal spacing of the main beam reinforcement is large. Finally, temporary fixing steel bars 9 are used to bind and fix the main beam reinforcement 5 and are located on both sides of the splicing plates, which play a role of temporarily fixing them on the main beam reinforcement.

[0026] Another embodiment, such as Figure 4 As shown, the splicing plate includes a third splicing plate 10 and a fourth splicing plate 11, and arc grooves 6 are provided on both side walls of the third splicing plate 10 and the fourth splicing plate 11, a square groove 7 is provided on one side wall of the third splicing plate 10, and a square protrusion 8 is provided on one side wall of the fourth splicing plate 11.
