[0002] A Chinese patent with announcement number CN214995261U discloses an assembled building construction grouting sleeve. When slurry comes out of the vent holes, the fan-shaped baffle is rotated to block the multiple vent holes, thereby preventing the slurry in the pipe body from leaking out of the vent holes, thereby preventing slurry waste. Grouting is then continuously performed into the pipe body to completely fill the pipe body with slurry and completely wrap the prefabricated end steel bars and the inserted end steel bars, making the hardened slurry more compact.
[0003] In the above patent, the grouting sleeve needs to be locked at both ends by a sleeve when grouting the steel bars to prevent the mud from flowing out. Once the steel bars are too long, the sleeve needs to be inserted from the end. The process is very cumbersome and cannot achieve efficient assembly operation. Utility Model Content
[0004] The purpose of the utility model is to provide an assembled grouting sleeve for building construction. When mud flows into the filling rubber ring, the filling rubber ring will be deformed due to pressure and then tightly fit against the inner wall of the port slot to prevent the outflow of mud, thereby realizing self-locking operation and eliminating the need for external sealing, which can solve the problems in the prior art.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] In order to solve the problem that the grouting sleeve needs to be locked with a sleeve at both ends to prevent the mud from flowing out when the steel bar is butt grouting, and once the steel bar is too long, the sleeve needs to be inserted from the end, which is a very cumbersome process and cannot achieve efficient assembly operation; please refer to Figure 1-3 , the utility model provides the following solutions:
[0020] A prefabricated grouting sleeve for building construction includes a sleeve body 1, a grouting port 101 is provided on the upper side of one side of the sleeve body 1, and a grouting port 102 is provided on the lower side of one side of the sleeve body 1, wherein the grouting port 101 and the grouting port 102 are provided as an integrated structure with the sleeve body 1, and port slots 103 are provided at both ends of the sleeve body 1, and a sealing ring 2 is provided inside the port slot 103, which can lock and limit the steel bars at the port slot 103.
[0021] Specifically, one end of the grouting port 101 and the grouting port 102 are both provided with threaded joints, the interior of the sleeve body 1 is provided with a pre-buried cavity 104 , and the middle section of the pre-buried cavity 104 is provided with an alignment baffle 1041 .
[0022] Specifically, the alignment baffle 1041 and the sleeve body 1 are configured as an integrated structure, and stress ring ribs 1042 are provided on both sides of the alignment baffle 1041. The stress ring ribs 1042 are welded to the sleeve body 1. The alignment baffle 1041 is mainly used to limit the steel bars entering at both ends to ensure that the lengths of the steel bars at both ends are consistent. The stress ring ribs 1042 can increase the tensile strength of the sleeve and the mud after the mud solidifies, thereby preventing the solidified mud from sliding inside the sleeve.
[0023] Specifically, the grouting port 101 and the grouting port 102 are connected through the embedded cavity 104 .
[0024] Specifically, a filling rubber ring 3 is provided on the inner side of the port slot 103. When in use, the steel bars need to be inserted from the inside of the filling rubber ring 3, and the inner side of the filling rubber ring 3 is in contact with the steel bars. A mounting support plate 301 is provided on the bottom of the filling rubber ring 3, wherein the mounting support plate 301 is welded to the sleeve body 1. When the mud is injected into the embedded cavity 104 through the grouting port 101, part of the mud will flow toward the port slots 103 at both ends. When the mud flows into the filling rubber ring 3, the filling rubber ring 3 will be deformed due to the pressure and then tightly fit with the inner wall of the port slot 103 to prevent the outflow of mud, thereby realizing self-locking operation without the need for external sealing.
[0025] Specifically, a flow limiting cone bucket 302 is provided at the bottom of the mounting support plate 301, and the flow limiting cone bucket 302 is connected to the mounting support plate 301 through a flange, wherein the flow limiting cone bucket 302 extends to one side of the grouting port 101 and the grouting port 102 respectively, and the narrow mouth area of the flow limiting cone bucket 302 faces the embedded cavity 104, which can effectively prevent a large amount of mud from flowing into the filling rubber ring 3 during pouring, limit the flow rate, and avoid the situation where the filling rubber ring 3 is dislocated due to large changes in pressure.
[0026] Working principle: when in use, the steel bar needs to be inserted from the port slot 103, and then the steel bar passes through the inside of the filling rubber ring 3 and enters the embedded cavity 104. The positioning baffle 1041 in the embedded cavity 104 is mainly to limit the steel bars entering at both ends to ensure that the length of the steel bars at both ends is consistent. The stress ring 1042 can increase the tensile strength of the sleeve and the mud after the mud solidifies, and avoid the sliding of the solidified mud inside the sleeve. When the mud is then injected into the embedded cavity 104 through the grouting port 101, part of the mud will flow to the port slots 103 at both ends. When the mud flows into the filling rubber ring 3, the filling rubber ring 3 will be deformed due to pressure and then tightly fit against the inner wall of the port slot 103 to prevent the outflow of mud, realizing self-locking operation without the need for external sealing.
