[0002] Currently, most of the splicing connectors used in prefabricated buildings are symmetrically embedded on both sides of the prefabricated components. However, when these connectors are used for connection, they exert significant tensile forces on the prefabricated components, leading to cracks between the components and the connectors and reducing the durability of the prefabricated components. To address this issue, a new technical solution is proposed. Utility Model Content

The reinforcing rod is provided with a first docking frame and a connecting frame. The first docking frame is placed at the left end of the reinforcing rod. The first docking frame is provided with a first semi-circular slot and a connecting bushing. The first semi-circular slot is symmetrically opened on the right side of the first docking frame and fitted onto the left end of the reinforcing rod. The connecting bushing is welded to the middle of the left end of the first docking frame. The connecting bushing is provided with a boss and a connecting internal thread. The boss is integrally formed and connected to the middle of the outer side of the connecting bushing. The connecting internal thread is opened inside the connecting bushing. The connecting frame is placed at the right end of the reinforcing rod.

[0005] Preferably, the connecting frame is provided with a second docking bracket and a through groove. The second docking bracket is integrally formed and connected to the left end of the connecting frame. The second docking bracket has a second semi-circular slot symmetrically opened on the left side. The second semi-circular slot is fitted onto the right end of the reinforcing rod. The through groove is opened in the middle of the right end of the connecting frame.

[0006] Preferably, a gasket is placed at the inner end of the through groove, and a through hole is formed in the middle of the gasket. The through hole is symmetrical in size and position to the through groove, and a connecting bolt is nested in the through hole.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: a connecting bolt is nested in the through hole, which can be connected to the connecting internal thread through the connecting bolt; the boss is integrally formed and connected to the middle of the outer side of the connecting bushing, which can effectively increase the firmness between the connecting bushing and the prefabricated component; the reinforcing rod is embedded in the prefabricated component, which can effectively improve the strength of the prefabricated component; in summary, this utility model can easily connect prefabricated buildings and effectively improve the tensile strength of prefabricated components.

Detailed Implementation

[0009] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0010] like Figure 1-3 As shown, a high-efficiency splicing connection structure for prefabricated buildings includes a reinforcing rod 1, which is embedded inside a prefabricated component. A first connecting frame 2 and a connecting frame 3 are provided on the reinforcing rod 1. The first connecting frame 2 is placed at the left end of the reinforcing rod 1 and has a first semi-circular slot 4 and a connecting bushing 5. The first semi-circular slot 4 is symmetrically located on the right side of the first connecting frame 2 and is fitted onto the left end of the reinforcing rod 1. The connecting bushing 5 is welded to the middle of the left end of the first connecting frame 2 and has a boss 6 and a connecting internal thread 7. The boss 6 is integrally formed and connected to the connecting shaft. The inner thread 7 is opened inside the outer middle of the sleeve 5. The connecting frame 3 is placed at the right end of the reinforcing rod 1. The connecting frame 3 is provided with a second docking bracket 8 and a through groove 9. The second docking bracket 8 is integrally formed and connected to the left end of the connecting frame 3. The second docking bracket 8 is symmetrically provided with a second semi-circular slot 10 on the left side. The second semi-circular slot 10 is fitted onto the right end of the reinforcing rod 1. The through groove 9 is opened in the middle of the right end of the connecting frame 3. A gasket 11 is placed in the inner end of the through groove 9. A through hole 12 is opened in the middle of the gasket 11. The size and position of the through hole 12 are symmetrical with those of the through groove 9. A connecting bolt 13 is nested in the through hole 12.

[0011] Specific usage: After connecting the reinforcing rod 1, the first docking frame 2, and the connecting frame 3, they are embedded equidistantly in the precast components; when splicing the precast components, the outer end of the connecting bushing 5 on the first precast component is fitted with the outer end of the connecting frame 3 on the second precast component, and then the gasket 11 is placed in the inner end of the through groove 9, and the connecting bolt 13 is threaded through the through hole 12, the through groove 9 and the connecting internal thread 7 in sequence; while the connecting bolt 13 tightens the connecting bushing 5, the resulting tension is transmitted to the reinforcing rod 1, which effectively reduces the tensile force borne by the precast components.
