[0023] In the implementation process, it is particularly worth pointing out that the left sleeve 1, the right sleeve 2, the end restraint ring 3, the middle restraint ring 4, the hinge 5 and the fixed card 6 are matched to form the full grouting sleeve main structure by the left and right sleeve units, that is, the left sleeve 1 and the right sleeve 2, and are connected through the hinge 5 installed on the end restraint ring 3 and the middle restraint ring 4, so that the left sleeve 1 and the right sleeve 2 can rotate relative to the hinge 5 as the shaft, and at the same time, through the fixed card 6, the left sleeve 1 and the right sleeve 2 after rotation can be fixed, so that the full grouting sleeve is sleeved on the connection of the two steels, ensuring the stability after connection, and through the cooperation between the left sleeve 1, the right sleeve 2, the end restraint ring 3, the middle restraint ring 4, the hinge 5, the fixed card 6, the grouting port 9 and the outlet port 10, the setting of the grouting port 9 and the outlet port 10 makes the grouting process more convenient, and the grouting material can be injected from the grouting port 9 to fill the gap between the left sleeve 1, the right sleeve 2 and the steel, until overflowing from the outlet port 10, ensuring the uniformity and compactness of grouting, further improving the strength and stability of the connection, and through the cooperation between the left sleeve 1, the right sleeve 2, the end restraint ring 3, the middle restraint ring 4, the hinge 5, the fixed card 6, the mortise 7 and the tenon 8, the mortise 7 and the tenon 8 are arranged on the side of the left sleeve 1 and the right sleeve 2 away from the hinge 5, and the connection strength and stability of the full grouting sleeve are improved by using the mortise and tenon structure, so that it has good anti-pulling performance and anti-seismic performance, and in the event of natural disasters such as earthquakes, the mortise and tenon structure can absorb and disperse seismic energy through its unique deformation capacity, thereby reducing the seismic response of the structure. Since the mortise and tenon connection completely relies on the strength and shape design of the component itself, it does not need to use nails, glue and other modern connecting materials, at the same time, the mortise and tenon structure allows the material to naturally shrink and expand with temperature and humidity changes, reducing stress damage caused by climate change, avoiding connection failure caused by material aging, corrosion and other reasons, thereby prolonging the service life of the overall structure, and through the cooperation between the left sleeve 1, the right sleeve 2, the end restraint ring 3, the middle restraint ring 4, the hinge 5, the fixed card 6, the mortise 7, the tenon 8, the grouting port 9 and the outlet port 10, the full grouting sleeve adopts a semi-separation design, the left sleeve 1 and the right sleeve 2 are buckled into the connection of the steel, and the fixed card 6 is used for fixation, the mortise and tenon structure is used for assembly, the end restraint ring 3 and the middle restraint ring 4 provide compressive stress for the full grouting sleeve, so that the full grouting sleeve can uniformly distribute stress when stressed, avoiding connection failure caused by stress concentration, thereby improving the reliability and durability of the overall structure, at the same time, the ends of the two steels can be adjusted in position first, and then the sleeve is assembled and installed, thereby allowing the component to have a certain deviation in the early stage of the installation process, reducing the operation space required for assembly, reducing the construction difficulty and improving the construction efficiency;

[0024] Furthermore, both ends of the left sleeve 1 and the right sleeve 2 are provided with through holes 11, and both ends of the left sleeve 1 and the right sleeve 2 are provided with sealing rings 12.

[0025] In the specific implementation process, it is worth noting that, through the cooperation between the left sleeve 1, the right sleeve 2, the through hole 11 and the sealing ring 12, the setting of the through hole 11 facilitates the insertion of the full grouting sleeve into the reinforcing bar. By setting the sealing ring 12 at the through hole 11, the grouting material is effectively prevented from leaking from the gap between the reinforcing bar and the through hole 11, thereby ensuring the compactness of the grouting and the stability of the connection. In addition, the design of the sealing ring 12 can simplify the construction process, reduce additional sealing treatment steps, and further improve construction efficiency.

[0026] Furthermore, a through hole 13 is provided inside the fixing clip 6 located on the left sleeve 1, and a screw hole 14 is provided inside the fixing clip 6 located on the right sleeve 2. A fixing bolt 15 passes through the inner wall of the through hole 13, and the fixing bolt 15 is threadedly connected to the screw hole 14.

[0027] In the specific implementation process, it is worth noting that, through the cooperation between the left sleeve 1, the right sleeve 2, the fixing clip 6, the through hole 13, the screw hole 14 and the fixing bolt 15, after the left sleeve 1 and the right sleeve 2 are fastened together, the fixing clip 6 located on the left sleeve 1 is close to the fixing clip 6 located on the right sleeve 2. By inserting the fixing bolt 15 into the screw hole 14 and screwing it into the screw hole 14 for fixation, a quick and stable connection between the left sleeve 1 and the right sleeve 2 is achieved, improving the assembly efficiency of the overall structure.

[0028] Furthermore, streamlined recesses 16 are equidistantly provided on the inner walls of the left sleeve 1 and the right sleeve 2. The streamlined recesses 16 are used to enhance the connection strength and stress performance between the sleeve, the cement-based grout and the connecting steel bars.

[0029] In the specific implementation process, it is worth noting that the streamlined concave rib 16 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. Compared with conventional concave and convex ribs, it is easier to make the grout fuller, which helps to reduce the air bubbles that may be generated during the grouting process, improve the density of the grout, and improve the convenience of grouting operation during construction.

[0030] Furthermore, both the grouting port 9 and the grout outlet 10 are provided with flared ends 17;

[0031] In the specific implementation process, it is worth noting that, through the cooperation between the grouting port 9, the grout outlet 10 and the flared opening 17, the connection between the grout outlet 9 and the grouting port 10 and the left sleeve 1 is designed with an outward-flaring opening to improve the convenience of grouting operation. The outward flow force of the grouting material is used to form a self-sealing effect on the grout outlet 9 and the grouting port 10, thereby preventing grout leakage and grout loss in the upper part of the sleeve, and enhancing the saturation and sealing of the sleeve grouting.
