DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Reference Figure 1-Figure 3 As shown, this embodiment provides a prefabricated structural steel bar sleeve grouting structure, including a grouting sleeve 1, a pre-buried steel bar 3 is installed on the top of the grouting sleeve 1, a connected steel bar 2 is installed on the bottom of the grouting sleeve 1, a grouting pipe 4 is fixedly connected to the side wall of the grouting sleeve 1 and connected, a grouting pipe 5 is provided below the grouting pipe 4, one end of the grouting pipe 5 is fixedly connected to and connected with the grouting sleeve 1, and an auxiliary sleeve 6 is installed on the other end of the grouting pipe 5, a sealing component is slidably connected in the auxiliary sleeve 6, the sealing component is detachably connected to the grouting pipe 5, a control component is fixedly connected to the sealing component, and the end of the control component extends out of the auxiliary sleeve 6.

[0022] When in use, the grouting sleeve 1 with the embedded steel bar 3 is sleeved on the connected steel bar 2, the auxiliary sleeve 6 is installed, and the mortar is pressure-filled into the grouting pipe 5 through the auxiliary sleeve 6 until the grouting sleeve 1 is filled. When the grouting sleeve 1 is full of mortar, it will overflow from the grouting pipe 4. When the mortar flowing out is in a linear shape, the filling can be stopped. At this time, the mortar inside the grouting sleeve 1 is uniform and full, and then the grouting pipe 4 is sealed, and the sealing component is driven to slide in the auxiliary sleeve 6 through the control component until the sealing component contacts the grouting pipe 5 and extends into the grouting pipe 5. The sealing component squeezes the mortar in the auxiliary sleeve 6 and the grouting pipe 5 to prevent the mortar from flowing out of the grouting pipe 5, and ensures the compactness of the mortar inside the grouting sleeve 1, thereby improving the stability of the structure; wherein the mortar production process is: about 70% dry material is added to water - stirred for 2 minutes - the remaining 30% dry material is poured in - stirred for 3 minutes - left to stand in the mixing barrel - grouting material fluidity detection - retained test blocks - pressure grouting. The utility model has a simple structure and is easy to use, and can quickly seal the grouting pipe 5 without causing leakage of mortar, thereby greatly improving the stability of the structural connection and enhancing the bearing capacity.

[0023] Further optimization scheme, the sealing component includes a baffle 13 slidably connected to the inner wall of the auxiliary sleeve 6, a threaded section 14 runs through the center of the baffle 13, the threaded section 14 is detachably connected to the grouting pipe 5, and the side walls of the baffle 13 and the threaded section 14 are respectively fixed to the control component. The control component drives the baffle 13 to slide in the auxiliary sleeve 6, drives the threaded section 14 to move, and the threaded section 14 extends into the grouting pipe 5 and then rotates to seal the grouting pipe 5, reduce the leakage of mortar, and improve the compactness of the inside of the grouting sleeve 1. The setting of the baffle 13 can block the mortar, ensuring that the mortar can only enter the grouting sleeve 1 from the grouting pipe 5.

[0024] In a further optimized solution, the control assembly includes a connecting rod 8 symmetrically fixed to the side wall of the baffle 13, the connecting rod 8 extends out of the auxiliary sleeve 6 and is fixed to a connecting plate 9. Pushing the connecting plate 9 drives the connecting rod 8 to move, and the connecting rod 8 drives the baffle 13 to move, thereby facilitating the rapid completion of the sealing work.

When the threaded section 14 extends into the grouting pipe 5, the knob 10 is turned, the knob 10 drives the center rod 11 to rotate, the center rod 11 drives the threaded section 14 to rotate, and the threaded section 14 is threadedly connected to the inner wall of the grouting pipe 5, thereby completing the plugging work.

[0026] In a further optimized solution, a plug 12 is fixedly connected to one end of the threaded section 14 away from the center rod 11, and the plug 12 is adapted to the inner diameter of the grouting pipe 5. When the baffle 13 and the threaded section 14 move, the plug 12 is driven to move, and the plug 12 first contacts the grouting pipe 5, squeezes the mortar into the grouting sleeve 1, and then rotates the threaded section 14 to complete the plugging, so that the end of the grouting pipe 5 is more tight and the possibility of leakage is reduced.

[0027] In a further optimized solution, the top of the auxiliary sleeve 6 is fixedly connected and connected with a connecting pipe 7, which is located between the grouting pipe 5 and the plug 12. The connecting pipe 7 is connected to an external pressure grouting device, and the mortar is input into the auxiliary sleeve 6 through the connecting pipe 7, and then flows into the grouting pipe 5 from the auxiliary sleeve 6, and finally injected into the grouting sleeve 1 from the grouting pipe 5 to complete the filling.

[0028] In a further optimized solution, one end of the auxiliary sleeve 6 is detachably connected to the grouting pipe 5, and the other end of the auxiliary sleeve 6 is fixedly connected to a sealing plate 15, and the connecting rod 8 and the center rod 11 are respectively slidably connected to the sealing plate 15. The sealing plate 15 supports the connecting rod 8 and the center rod 11 to ensure the stability of the sliding process.

[0029] In a further optimized solution, one end of the auxiliary sleeve 6 away from the sealing plate 15 is open, an internal thread is engraved in the open end, and an external thread is engraved on the end of the grouting pipe 5, and the external thread is adapted to the internal thread. The internal thread and the external thread are provided to facilitate the installation of the auxiliary sleeve 6 and the grouting pipe 5, and improve the construction speed.
