[0017] 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.

[0018] In the existing technology, when using grouting sleeves to connect reinforcing bars, the connection and alignment of the reinforcing bars require a large operating space, which weakens the overall stability of the precast components. Furthermore, during the installation phase of the precast components, the operation of connecting the reinforcing bars and installing the devices is highly complex, resulting in relatively low construction efficiency.

[0019] In view of this, the present invention provides a novel prefabricated fully grouted sleeve. Through the cooperation of the upper sleeve, lower sleeve, connecting sleeve, compression spring, sliding vertical groove, sliding inclined groove, limiting groove, limiting rod, grouting port and grout outlet, the sleeve adopts a split design, which allows the ends of the two reinforcing bars to be adjusted in position first, and then the upper and lower sleeves are assembled and installed by snap-fit ​​fixing. This effectively controls the operating space when connecting reinforcing bars, reduces the reserved space and the range of the post-cast area, thereby improving the integrity of the component. Even if there is a certain deviation in the position of the reinforcing bars when the component is in place, the connection operation can be carried out smoothly. It also effectively simplifies the operation steps of connecting and aligning reinforcing bars, reduces the construction difficulty, and significantly improves the construction efficiency.

[0020] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0021] Depend on Figures 1-5 It is known that a novel prefabricated grouting sleeve includes an upper sleeve 1, a lower sleeve 2 below the upper sleeve 1, and a connecting sleeve 3 at the top of the lower sleeve 2. The upper sleeve 1 is inserted into the connecting sleeve 3. A compression spring 4 is connected inside the connecting sleeve 3. The compression spring 4 provides elastic force to the upper sleeve 1 to move away from the lower sleeve 2. The two ends of the compression spring 4 are respectively pressed against the upper sleeve 1 and the lower sleeve 2. Sliding vertical grooves 5 are opened on both sides of the connecting sleeve 3. The connecting sleeve 3 is located at... A sliding inclined groove 6 is provided on one side of the bottom of the sliding vertical groove 5. The sliding inclined groove 6 is connected to the sliding vertical groove 5. A limiting groove 7 is provided at the end of the connecting sleeve 3 away from the sliding vertical groove 5. The limiting groove 7 is connected to the sliding inclined groove 6. Limiting rods 8 are provided on both sides of the outer wall of the upper sleeve 1. The limiting rods 8 are in clearance fit with the sliding vertical groove 5, the sliding inclined groove 6 and the limiting groove 7. A grouting port 9 is provided on one side of the outer wall of the lower sleeve 2 and a grout outlet 10 is provided on one side of the outer wall of the upper sleeve 1.

[0022] In the specific implementation process, it is worth noting that the main structure of the fully grouted sleeve is formed by the cooperation between the upper sleeve 1, the lower sleeve 2, and the connecting sleeve 3. By inserting and fixing the upper sleeve 1 into the connecting sleeve 3, a rapid connection between the upper sleeve 1 and the lower sleeve 2 is achieved. The sleeve adopts a split design, with the upper sleeve 1 and the lower sleeve 2 respectively fitted onto the ends of the two connecting reinforcing bars. This allows the ends of the two reinforcing bars to be adjusted in position before assembling and installing the upper sleeve 1 and the lower sleeve 2. This effectively controls the operating space during reinforcing bar connection, reduces the reserved space and the area of ​​the post-cast zone, thereby improving the overall integrity of the component. Even if there is a certain deviation in the position of the reinforcing bars when the component is in place, the connection operation can be carried out smoothly, reducing construction difficulty and significantly improving construction efficiency. The compression spring 4 provides elastic force to the upper sleeve 1, moving it away from the lower sleeve 2. Through the cooperation between the upper sleeve 1, lower sleeve 2, connecting sleeve 3, compression spring 4, sliding vertical groove 5, sliding inclined groove 6, limiting groove 7, and limiting rod 8, the limiting rod 8 is aligned with the sliding vertical groove 5. When the upper sleeve 1 is inserted into the connecting sleeve 3, the limiting rod 8 slides downward along the sliding vertical groove 5, compressing the compression spring 4. After reaching the end of the sliding vertical groove 5, the upper sleeve 1 is rotated, causing the limiting rod 8 to move from the sliding vertical groove 5 to the sliding inclined groove 6. Under the elastic action of the compression spring 4, the limiting rod 8 slides along the sliding inclined groove 6 towards the limiting groove 7, and finally engages inside the limiting groove 7, thus limiting and fixing the upper sleeve 1 inside the connecting sleeve 3, achieving the upper sleeve... The upper sleeve 1 and the lower sleeve 2 are assembled and installed together, and the compression spring 4 is used to press against the upper sleeve 1 to prevent loosening or separation between the upper sleeve 1 and the lower sleeve 2, thereby improving the stability and connection strength of the overall structure. Through the cooperation between the upper sleeve 1, the lower sleeve 2, the connecting sleeve 3, the grouting port 9 and the grout outlet 10, after the sleeve is assembled and installed, high-strength, early-strength, and micro-expandable cement-based grout is injected into the sleeve through the grouting port 9, and excess grout is discharged through the grout outlet 10 to ensure that the sleeve is full of grout. After the grout solidifies, it forms a tight connection with the sleeve and the reinforcing steel. The connection force between the reinforcing steel is composed of the bonding force of the grout, the friction force between the sleeve and the concrete, and the mechanical interlocking force. The multiple connection methods improve the connection performance of the reinforcing steel. Significantly improved, the structure is safer and more reliable, ensuring a tight connection between the reinforcing bars and the sleeve, thereby enhancing the overall load-bearing capacity and stability of the structure. This makes the fully grouted sleeve perform better under extreme conditions such as earthquakes and wind resistance. Through the cooperation of the upper sleeve 1, lower sleeve 2, connecting sleeve 3, compression spring 4, sliding vertical groove 5, sliding inclined groove 6, limiting groove 7, limiting rod 8, grouting port 9, and grout outlet 10, the sleeve adopts a separate design, allowing the ends of the two reinforcing bars to be adjusted first, and then the upper sleeve 1 and lower sleeve 2 are assembled and installed using a snap-fit ​​method. This effectively controls the operating space during reinforcing bar connection, reduces the reserved space and the area of ​​the post-cast zone, thereby improving the overall integrity of the component, even if there is a certain deviation in the position of the reinforcing bars when the component is in place.It also allows for smooth connection operations, effectively simplifies the steps of rebar connection and alignment, reduces construction difficulty, and significantly improves construction efficiency;

[0023] Furthermore, positioning rings 11 are provided at opposite ends of the upper sleeve 1 and the lower sleeve 2. Connecting rods 12 are provided at equal intervals on the outer side of the positioning rings 11. The two positioning rings 11 are fixedly connected to the upper sleeve 1 and the lower sleeve 2 respectively through the connecting rods 12. A rubber ring 13 is provided inside the positioning ring 11. Adaptive grooves 14 are provided at equal intervals on the inner wall of the rubber ring 13.

[0024] In the specific implementation process, it is worth noting that through the cooperation between the upper sleeve 1, lower sleeve 2, positioning ring 11, connecting rod 12, rubber ring 13 and adapter groove 14, when the sleeve is fitted into the end of the rebar joint, the rebar is stuck into the inside of the rubber ring 13. The elasticity of the rubber ring 13 provides initial positioning and support for the rebar, keeping the axis of the rebar and the sleeve consistent. This prevents the sleeve from loosening or shifting during grouting, improving the connection strength and stress uniformity after the sleeve is assembled. At the same time, the adapter groove 14 on the inner side of the rubber ring 13 can accommodate rebars of different diameters and ensure that the grout flows through the adapter groove 14, increasing the applicability and flexibility of the sleeve and helping to improve its versatility and practicality.

[0025] Furthermore, the upper sleeve 1 and the lower sleeve 2 are provided with a constriction 15 at their ends that are far apart from each other. The end of the constriction 15 is provided with a through hole 16. A sealing ring 17 is provided inside the constriction 15. Both ends of the grouting port 9 and both ends of the grout outlet 10 are provided with flared openings 20.

[0026] In the specific implementation process, it is worth noting that through the cooperation between the upper sleeve 1, the lower sleeve 2, the constriction opening 15, and the reinforcement insertion hole 16, by setting the constriction opening 15 at the end of the upper sleeve 1 and the lower sleeve 2 and opening the reinforcement insertion hole 16, the end of the sleeve is contracted inward, allowing the reinforcement to be inserted into the sleeve through the reinforcement insertion hole 16. After the sleeve is installed, the grout forms a relatively tight barrier at the constriction opening 15, which not only enhances the structural strength of the sleeve end but also allows the sleeve to better cooperate with the reinforcement during installation, ensuring the uniformity and density of the grouting. The sealing ring 17 is used to seal the gap between the steel bar and the through hole 16 to prevent the grout from leaking out of the gap between the steel bar and the through hole 16. Through the cooperation between the grouting port 9, the grout outlet 10 and the flared end 20, both ends of the grouting port 9 and the grout outlet 10 are designed to be turned outward, which improves the convenience of grouting operation. The outward flow force of the grouting material forms a self-sealing effect on the grouting port 9 and the grout outlet 10, thereby avoiding grout leakage and grout detachment from the upper part of the sleeve, and enhancing the saturation and sealing of the sleeve grouting.

[0027] Furthermore, recesses 18 are provided at equal intervals on the inner walls of both the upper sleeve 1 and the lower sleeve 2. The recesses 18 are used to enhance the connection strength and stress performance between the sleeve, the cement-based grout and the connecting steel bars, so that the bonding material can obtain good mechanical friction resistance on the inner wall of the sleeve.

[0028] In the specific implementation process, it is worth noting that the concave 18 is used to enhance the connection strength and stress performance between the sleeve, cement-based grout and connecting steel bars, so that the bonding material can obtain good mechanical friction resistance on the inner wall of the sleeve.

[0029] Furthermore, the outer walls of the upper sleeve 1, lower sleeve 2 and connecting sleeve 3 are provided with anti-slip textures 19 at equal intervals. The anti-slip textures 19 are used to increase the friction of the outer wall of the grouting sleeve, so that the user can better grip and rotate the sleeve when using it.

[0030] In the specific implementation process, it is worth noting that the anti-slip texture 19 is used to increase the friction of the outer wall of the grouting sleeve, so that the user can better hold and rotate the sleeve during use, avoiding slippage or poor rotation. This can effectively improve the stability and safety of the operation. Furthermore, after the concrete is poured, it can increase the bonding force between the concrete and the sleeve, ensuring the sleeve's firmness in the concrete.
