[0002] The grouting sleeve is a combination of a specially processed sleeve, matching grouting materials and steel bars. When connecting the steel bars, quick-hardening non-shrinkage grouting material is injected. The steel bars and sleeves are connected by relying on the bonding and bite action between the materials. The sleeve grouting joint has the advantages of reliable performance, wide applicability and easy installation. According to the filling method, it is divided into full grouting sleeve and semi grouting sleeve.

[0003] In the prior art, when the full grouting sleeve is used to butt the steel bars, since one end of the steel bar is inserted into the sleeve, the connecting steel bar may not be in the center of the sleeve, which causes the two steel bars to be offset during the grouting process, making the butt position of the two steel bars relative to one end not stable enough; in addition, after the slurry inside the sleeve is filled, before the slurry solidifies, when the filling head is pulled out, part of the slurry will flow out from the slurry port, and gaps are likely to exist in the later solidification, thereby affecting the quality of the project. Therefore, the utility model designs a prefabricated concrete component grouting sleeve connection device to solve the problems existing in the prior art. Utility Model Content

By arranging the plugging components 7 inside the grouting pipe 2 and the grouting pipe 3 opposite to each other, the grouting pipe and the grouting pipe after filling can be plugged in time to prevent the grouting sleeve body 1 from losing the grouting liquid after filling, thereby improving the grouting quality.

[0020] See also Figure 2In the embodiment of the utility model: the positioning assembly 6 includes: a connecting column 601, and four connecting columns 601 are provided. The four connecting columns 601 are fixedly installed at the middle position of the inner wall of the grouting sleeve body 1 at equal intervals along the circumference. A threaded sleeve 602 is fixedly installed between one end of the four connecting columns 601, and the inside of the threaded sleeve 602 is threadedly installed with one end of the threaded steel bar 4. The inside of the threaded sleeve 602 is provided with a thread groove corresponding to the surface thread of the threaded steel bar 4. When two threaded steel bars 4 are butted inside the grouting sleeve body 1, by rotating the threaded steel bars 4, one end of the two threaded steel bars 4 at the upper and lower ends inside the grouting sleeve body 1 can be rotated to the inside of the threaded sleeve 602. This installation method makes the steel bar connection of the full grouting sleeve accurate, simple, efficient and light, and avoids the displacement of the butt joint position of the two threaded steel bars 4 during grouting, which affects the grouting quality.

[0021] See also Figure 2 In the embodiment of the present invention, the upper and lower ends of the inner wall of the threaded sleeve 602 are both provided with thread grooves, and the thread directions of the upper and lower ends are arranged in opposite directions. The arrangement of the threaded grooves inside the threaded sleeve 602 facilitates the butt joint of the two opposite ends of the threaded steel bars 4, and improves the stability of the butt joint of the threaded steel bars 4.

[0022] See also Figure 2-3 In an embodiment of the utility model: the sealing assembly 7 includes: a sealing ring 701 and a connecting block 702, the sealing ring 701 is fixedly installed on one side of the inner wall of the grouting pipe 3, the connecting block 702 is fixedly installed on the other side of the inner wall of the grouting pipe 3, a T-shaped movable rod 703 is movably provided through the middle of the connecting block 702, and one end of the T-shaped movable rod 703 is fixedly connected to a sealing block 704, the surface of one side of the sealing block 704 is built on the inner wall of one side of the sealing ring 701, the surface of the T-shaped movable rod 703 is covered with a reset spring 705, and one end of the reset spring 705 is fixedly connected to the surface of the sealing block 704, and the other end of the reset spring 705 is fixedly connected to the surface of the connecting block 702. When the grouting sleeve body 1 is filled with slurry, the filling head is installed at the end of the grouting pipe 3. After the slurry enters the grouting pipe 3, it squeezes and pushes the sealing block 704 to move away from the sealing ring 701, and the return spring 705 is squeezed and contracted. At this time, the slurry enters the interior of the grouting sleeve body 1. After filling, the slurry moves away from the corresponding sealing ring 701 by squeezing the sealing block 704 inside the grouting pipe 2. After the slurry flows out from the end of the grouting pipe 2, the filling is stopped. At this time, the slurry inside the grouting sleeve body 1 is no longer flowing, and the sealing block 704 is no longer squeezed by external force. Since the filled slurry is in a fluid state, the return spring 705 has little effect on the expansion and contraction. After the return spring 705 is stressed, it elastically resets, so that the sealing block 704 is squeezed on the inner wall of the corresponding sealing ring 701, completing the sealing of the slurry, avoiding the loss of slurry that has not yet solidified, and affecting the filling quality inside the grouting sleeve body 1.

[0023] See also Figure 2-3 In the embodiment of the utility model, one side of the inner ring of the blocking ring 701 is set to be conical, and one side of the blocking block 704 is set to be a conical surface that matches the inner ring of the blocking ring 701. The conical surface on one side of the blocking block 704 matches the conical inner ring of the blocking ring 701, so that when the return spring 705 pushes the blocking block 704 to approach the inner ring of the blocking ring 701, the blocking effect is improved to prevent the slurry filled in the grouting sleeve body 1 from being lost.

[0024] See also Figure 1-3 In the embodiment of the utility model, the inner diameter of the grouting pipe 3 and the grouting pipe 2 is twice the width of the connecting block 702. When the grouting slurry enters the grouting sleeve body 1 through the grouting pipe 3, since the inner diameter of the grouting pipe 3 is greater than the width of the connecting block 702, the grouting slurry can smoothly enter the grouting sleeve body 1, and can flow out from the end of the grouting pipe 2 after the grouting slurry is filled, so that the grouting situation of the grouting slurry can be observed.

[0025] Working principle: When the assembled concrete component grouting sleeve connection device is used, firstly, the two threaded steel bars 4 are butt-jointed through the positioning assembly 6 inside the grouting sleeve body 1, and the two threaded steel bars 4 are respectively inserted from the two ends of the grouting sleeve body 1. By rotating the threaded steel bars 4, one end of the two threaded steel bars 4 at the upper and lower ends inside the grouting sleeve body 1 can be rotated to the inside of the threaded sleeve 602 for threaded installation, which can prevent the butt joint position of the two threaded steel bars 4 from shifting during grouting. The filling head is installed at the end of the grouting pipe 3, and the slurry enters the grouting pipe 3 and is squeezed and pushed The dynamic blocking block 704 moves away from the blocking ring 701, and the reset spring 705 is squeezed and contracted. At this time, the slurry enters the interior of the grouting sleeve body 1. After filling, the slurry moves away from the corresponding blocking ring 701 by squeezing the blocking block 704 inside the grouting pipe 2. After the slurry flows out from the end of the grouting pipe 2, the filling is stopped. At this time, the slurry inside the grouting sleeve body 1 is no longer flowing, and the blocking block 704 is no longer squeezed by external force. The reset spring 705 is elastically reset after being stressed, so that the blocking block 704 is squeezed on the inner wall of the corresponding blocking ring 701, completing the slurry blocking.
