[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] See also Figure 1-4 , in the figure: This embodiment is a preferred implementation of the technical solution, a building concrete prefabricated component connection structure, including a component 1 and a component 2 embedded and fixed in the prefabricated concrete structure, the component 1 and the component 2 2 are matched and fixed with each other; the component 1 includes a connecting body 11, a sleeve 12 fixed to the end of the connecting body 11, an inner sleeve 13 integrally arranged in the middle of the connecting body 11, a plug rod 14 filled and fixed inside the inner sleeve 13, positioning holes 15 irregularly distributed on the circumference of the inner sleeve 13, and a marking rod 16 fixed in the middle position inside the inner sleeve 13; the component 2 includes a connecting body 21, a sleeve 22 fixed to the end of the connecting body 21, an outer sleeve 23 integrally arranged in the middle of the connecting body 21, a positioning column 24 arranged in the middle position inside the outer sleeve 23, a slot 25 opened inside the end face of the positioning column 24, and a positioning block 26 elastically arranged between the inner wall of the outer sleeve 23 and the circumference of the positioning column 24;

[0022] It should be noted that: in the building concrete prefabricated component connection structure involved in the present application, by setting the connection between component 1 and component 2 2, the assembly and fixation between the prefabricated concrete components are assisted. The structure is simple and the assembly is convenient, and the process does not require welding or bolting. The automatic assembly and fixation of component 1 and component 2 2 can realize the rapid assembly between the prefabricated concrete components, and the connection between component 1 and component 2 2 relative to the concrete components is stable, the force is uniform, and it is not easy to break or deform.

[0023] Among them Figure 1 As shown, the connecting body 11, the sleeve 12, the connecting body 21 and the sleeve 22 are all embedded and fixed inside the edge of the assembled concrete structure, and the connecting body 11, the sleeve 12, the connecting body 21 and the sleeve 22 are all tubular structures;

[0024] It should be noted that the component 1 and the component 2 are both embedded parts. When manufacturing prefabricated concrete components, the connection body 11, the sleeve 12, the connection body 21 and the sleeve 22 are fixed inside the component in advance, and fixed structures such as steel bars are inserted into the connection body 11, the sleeve 12, the connection body 21 and the sleeve 22 to reinforce the position of the component 1 and the component 2.

[0025] Among them Figure 2 As shown, the connecting body 11 is arranged perpendicularly to the axial direction of the sleeve 12, and the connecting body 21 is arranged perpendicularly to the axial direction of the sleeve 22;

[0026] It should be noted that: the middle parts of the connecting body 11, the sleeve 12, the connecting body 21 and the sleeve 22 are all inserted with a steel bar fixing structure. Therefore, the relative directions of the above structures are set so that the component 1 and the component 2 2 can remain relatively stable relative to the concrete component and the axial force is uniform;

[0027] The end of the inner sleeve 13 is rounded, and the inner sleeve 13 is arranged in a gap formed by the inner wall of the outer sleeve 23 and the circumference of the positioning column 24; the positioning column 24 is inserted into the inner sleeve 13, and the insertion rod 14 and the marking rod 16 are inserted into the slot 25;

[0028] It should be noted that the rounded corners at the end of the inner sleeve 13 are used to facilitate the squeezing of the positioning block 26 by its edge to avoid interference of the positioning block 26 with the movement of the inner sleeve 13. After the inner sleeve 13 and the outer sleeve 23 are fully matched, the insertion rod 14 and the marking rod 16 are also fully matched with the slot 25. The positioning column 24 is fully inserted into the inner sleeve 13 to form a complete receiving structure. Among them, the marking rod 16 is used to assist in the alignment marking of several of the insertion rods 14 and the slots 25 when component 1 and component 2 2 cooperate with each other. The marking rod 16 first enters the slot 25 to realize the movement and positioning of the subsequent insertion rods 14.

[0029] Among them Figure 4 As shown, the positioning block 26 is embedded in the inner wall of the outer sleeve 23 through a spring, and the positioning block 26 and the positioning hole 15 are arranged in a one-to-one correspondence;

[0030] It should be noted that: as the outer sleeve 23 moves relative to the inner sleeve 13, the positioning block 26 is squeezed by the end of the inner sleeve 13 at the moment it contacts the inner sleeve 13, so that the positioning block 26 is compressed into the outer sleeve 23. As the inner sleeve 13 gradually enters into the outer sleeve 23, when the positioning hole 15 moves to the positioning block 26, the positioning block 26 loses external constraints and pops out from the inner wall of the outer sleeve 23 under the action of the spring, cooperating with the positioning hole 15 to assist in the positioning between the outer sleeve 23 and the inner sleeve 13.
