[0003] Specifically, the lower side wall of the grouting sleeve is provided with the pulp inlet, and the upper side wall is provided with the pulp outlet, the reinforcement of one prefabricated component is connected with the upper end of the sleeve through the thread, and the reinforcement of another prefabricated component is inserted into the sleeve, after assembly, the matched grouting material is injected through the pulp inlet, and the two prefabricated components are connected through the out of the pulp structure of the grouting sleeve.The connecting structure not only has the connecting effect higher than the strength of the reinforcement base material, but also ensures the compactness of the sleeve and the firm adhesion of the reinforcement and the sleeve.

[0004] However, since the pulp outlet of the grouting sleeve has a height interval with the top of the grouting sleeve, when grouting, as the grouting material level gradually rises, the cylinder segment between the top of the grouting sleeve and the pulp outlet forms an air column, and the grouting material cannot effectively enter the air column segment, resulting in no grouting body in the air column segment of the grouting sleeve and zero performance.

[0005] Therefore, how to design an out of the pulp structure of the grouting sleeve to avoid the formation of an air column cavity in the cylinder segment is a problem to be solved by those skilled in the art. SUMMARY

[0006] The utility model aims at the shortage of prior art, provides a kind of out of the pulp structure of grouting sleeve, its structure is simple, processing cost is low, can effectively exhaust to ensure that matched grouting material fills full sleeve inner cavity, avoid to appear quality problem.

[0007] The technical scheme of the utility model is: a kind of out of the pulp structure of grouting sleeve, including sleeve body, the lower side wall of sleeve body is provided with pulp inlet, and the upper side wall is provided with pulp outlet, the upper end inner cavity wall of sleeve body is provided with thread section, forms reinforcement connecting section, the lower end inner cavity of sleeve body forms reinforcement insertion section, the partition between reinforcement connecting section, reinforcement insertion section is located above pulp outlet, still include exhaust pipe, the exhaust pipe is L-shaped, the horizontal section of L-shaped exhaust pipe is fixed in the top inner wall of pulp outlet, the vertical section of L-shaped exhaust pipe is located in the reinforcement insertion section of sleeve body, and it extends upwards, with the interval distance of partition.

[0008] The bottom surface of the partition is provided with an upwardly recessed accommodation cavity, and the vertical section of the exhaust pipe extends into the accommodation cavity.

[0009] The accommodation cavity is close to the pulp outlet.

[0010] The horizontal section of the exhaust pipe is fixed on the top of the inner wall of the slurry outlet by spot welding.

[0011] The extending end of the horizontal section of the exhaust pipe does not exceed the slurry outlet.

[0012] The exhaust pipe is a circular pipe, and the vertical section and the horizontal section of the exhaust pipe are connected by an arc-shaped transition.

[0013] The above technical scheme has the following beneficial effects:

[0014] 1. The slurry outlet structure of the grouting sleeve comprises a sleeve body, an inlet is arranged on the lower side wall of the sleeve body, and a slurry outlet is arranged on the upper side wall of the sleeve body, the grouting material is pressurized to enter the inner cavity of the sleeve body from the inlet on the lower side wall, and gradually fills the inner cavity of the sleeve body. A threaded section is arranged on the inner cavity wall of the upper end of the sleeve body to form a steel bar connecting section, and the inner cavity of the lower end of the sleeve body forms a steel bar insertion section. The sleeve body is first sleeved on the steel bar of the lower prefabricated part, and then is threadedly connected with the steel bar of the upper prefabricated part through the threaded section. After sealing, the grouting material is pressurized to enter the inner cavity of the sleeve body through the inlet. A partition plate is arranged between the steel bar connecting section and the steel bar insertion section, and the partition plate is located above the slurry outlet. The partition plate can limit the threaded connection position of the sleeve body and ensure the connection strength of the sleeve body and the upper prefabricated part. An exhaust pipe is further arranged, the exhaust pipe is in an L shape, the horizontal section of the L-shaped exhaust pipe is fixed on the inner wall of the slurry outlet, the vertical section of the L-shaped exhaust pipe is located in the steel bar insertion section of the sleeve body and extends upward with a spacing distance from the partition plate, so that the exhaust pipe is prevented from being blocked in advance due to turbulence during the rising of the grouting material, and smooth exhaust is ensured. As the liquid level of the grouting material continuously rises, when the liquid level of the grouting material exceeds the slurry outlet, an air column is formed in the cavity section of the inner cavity of the sleeve body above the slurry outlet. The air column is extruded out of the inner cavity of the sleeve body through the exhaust pipe. When the grouting material fills the air column section, the exhaust pipe remaining in the inner cavity of the sleeve body further forms a reinforcing rib to play a reinforcing role.

[0015] 2. The bottom surface of the partition plate is provided with an upwardly recessed accommodation cavity, and the vertical section of the exhaust pipe extends into the accommodation cavity. In this way, the exhaust pipe can be effectively prevented from being blocked in advance due to turbulence during the rising of the grouting material, and smooth exhaust is ensured.

[0016] 3. The extending end of the horizontal section of the exhaust pipe does not exceed the slurry outlet. Under the premise of meeting the exhaust requirement, the slurry outlet can be conveniently blocked by the staff in the later period, and the actual demand is met.

[0017] The above and other objects, features and advantages of the present application will become apparent from the following description of the preferred embodiments, taken in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF DRAWINGS
