Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0029] Embodiment 1

[0030] As shown in Figure 1 , Figure 4 The utility model provides grouting sleeve sealing mechanism of assembly type building, including wall body one 1 and wall body two 2 with wall body one 1 assembly, wall body one 1 inside is embedded with grouting sleeve shell 7, and the lower end of grouting sleeve shell 7 is flush with the lower end of wall body one 1, and the outer wall and inside of grouting sleeve shell 7 are equally divided array fixed with a plurality of reinforcing rings 8, and the reinforcing ring 8 of grouting sleeve shell 7 outside is clamped and fixed with the inner wall of wall body one 1, and this installation mode is existing and conventional mode and will not be described in detail.

[0031] As shown in Figure 2 , Figure 3As shown, the middle part of the inner cavity of the grouting sleeve shell 7 is provided with a clamping mechanism 4 for longitudinally limiting the steel bars 3, and the reinforcing ring 8 at the middle part of the inner cavity of the grouting sleeve shell 7 is fixedly provided with a fixed ring seat 12. The fixed ring seat 12 can support the fixed sleeve 41. The surface of the fixed ring seat 12 is equally divided into multiple through holes. The through holes are connected to the inside of the grouting sleeve shell 7, so that the grout flows in the grouting sleeve shell 7. The clamping mechanism 4 includes a fixed sleeve 41 fixedly penetrating the middle part of the fixed ring seat 12. Both ends of the fixed sleeve 41 are provided with circular grooves for inserting the steel bars 3, but the two circular grooves are not connected, and the diameter of the circular groove is much larger than the diameter of the steel bar 3. Both ends of the inner cavity of the fixed sleeve 41 are fixedly provided with tapered sheets 42. The convex parts of the two tapered sheets 42 are oppositely arranged, so that when the steel bars 3 are inserted into the middle part of the tapered sheets 42, the ribs on the surface of the steel bars 3 are clamped by the tapered sheets 42, thereby achieving the fixing effect of the steel bars 3. The diameter of the tapered sheet 42 is larger than the diameter of the steel bar 3, so that the steel bar 3 can be smoothly inserted. At the same time, the tapered sheet 42 has a slope that converges to the middle part, which can guide the insertion of the steel bar 3 and make the insertion of the steel bar 3 more smooth. The longitudinal axis of the steel bar 3 coincides with the center of the tapered sheet 42, so that the steel bar 3 can be smoothly inserted into the fixed sleeve 41 to achieve the fixing effect of the steel bar 3.

[0032] As shown in Figure 1 , Figure 2 , Figure 6 , the sealing assembly 6 is used to seal the openings at both ends of the grouting sleeve shell 7. Each steel bar 3 penetrates the sealing assembly 6. Two sealing assemblies 6 are arranged inside the wall body 1 and on the upper end of the wall body 2. The sealing assembly 6 is provided with two cover plates 61. The middle part of each cover plate 61 is provided with a hole for the steel bar 3 to pass through. The two steel bars 3 penetrate the holes in the middle part of the cover plate 61 and are fixed by welding. It should be noted that the axis of the hole in the middle part of the cover plate 61 coincides with the center of the tapered sheet 42, so that the cover plate 61 and the steel bar 3 are welded and fixed to achieve better sealing. The sealing assembly 6 includes a cover plate 61 inserted into the end of the grouting sleeve shell 7. The diameter of the cover plate 61 is the same as the outer diameter of the grouting sleeve shell 7. A trapezoidal ring 62 is fixedly arranged around the end of the cover plate 61 facing the grouting sleeve shell 7. The installation structure of the trapezoidal ring 62 and the cover plate 61 is shown in Figure 2 . When the trapezoidal ring 62 is inserted into the abutting groove 10 and the sharp part 63 abuts against the abutting groove 10, a gap is left between the outer wall of the trapezoidal ring 62 and the horizontal through groove 9, so that the grout can flow downward from the vertical through groove 11. The upper end of the trapezoidal ring 62 is provided with a sharp part 63. The openings at both ends of the grouting sleeve shell 7 are provided with abutting grooves 10. The depth of the abutting groove 10 is 2mm less than the height of the trapezoidal ring 62, so that the cover plate 61 and the grouting sleeve shell 7 are completely abutted and fixed. The bottom of the abutting groove 10 abuts against the sharp part 63 and achieves hard sealing.

[0033] As shown in Figure 2、 Figure 5 As shown in the drawings, the grouting sleeve shell 7 is located on the wall body 1 side near the end of the grouting sleeve shell 7, and a horizontal through groove 9 is formed, the horizontal through groove 9 is not a bidirectional through groove, and a vertical through groove 11 communicating with the horizontal through groove 9 is formed at the position opposite to the horizontal through groove 9 on the inner wall of the grouting sleeve shell 7, the horizontal through groove 9 and the vertical through groove 11 form an "L" shape, the vertical through groove 11 penetrates through one end of the grouting sleeve shell 7 away from the horizontal through groove 9 and communicates with the outside, the lower end of the vertical through groove 11 communicates with the gap between the wall body 1 and the wall body 2, and then part of the slurry enters the gap between the wall body 1 and the wall body 2, thereby improving the connection stability of the wall body 1 and the wall body 2.

[0034] It should be noted that two steels 3 are respectively implanted in the wall body 1 and the wall body 2 in advance.

[0035] The principle and process of the utility model are as follows:

[0036] When the device is used, the user first inserts the two cover plates 61 into the steels 3 of the wall body 1 and the steels 3 of the wall body 2 and then fixes them by welding.

[0037] Then, the construction person inserts the grouting sleeve shell 7 into the upper end of the cover plate 61 of the wall body 1, and then inserts one end of the steel 3 into the middle of the conical sheet 42 and makes the one end of the steel 3 located in the inside of the fixing sleeve 41, and the rib of the steel 3 is locked by the conical sheet 42, at this time, the grouting sleeve shell 7 is in close contact with the cover plate 61 under the self weight, then the user pours the slurry into the inside of the grouting sleeve shell 7, the slurry will flow to the lower end of the inside cavity of the grouting sleeve shell 7 through the through hole of the fixing ring seat 12 and accumulate, at the same time, the slurry will flow into the inside of the fixing sleeve 41 through the gap between the conical sheet 42 and the steel 3.

[0038] The fixing sleeve 41 can also adopt other structures, including but not limited to that a plurality of circular holes communicating with the inside of the fixing sleeve 41 are formed on the surface of the fixing sleeve 41, so that the slurry outside can enter the fixing sleeve 41 through the circular holes and then fix the steel 3.

[0039] When the slurry is about to fill the grouting sleeve shell 7, at this time, the slurry will overflow the horizontal through groove 9, stop pouring, the slurry will enter the vertical through groove 11 through the horizontal through groove 9 and fall into the gap between the wall body 1 and the wall body 2 under the action of gravity and fill, until the slurry overflowing the horizontal through groove 9 in the grouting sleeve shell 7 is discharged.

[0040] Subsequently, the wall body two 2 is lifted by the loading device, the reinforcing steel bars 3 of the wall body two 2 are inserted into the grouting sleeve shell 7 and the inside of the fixing sleeve 41, and the reinforcing steel bars 3 are fixed by the tapered sheet 42, when the reinforcing steel bars 3 are inserted into the inside of the grouting sleeve shell 7, the inside grout is extruded, and the excess grout is discharged through the horizontal through groove 9, therefore, the construction person needs to determine the grout injection amount according to the actual situation, so as to avoid the waste.

[0041] When the cover plate 61 of the wall body two 2 is clamped on the grouting sleeve shell 7 and the hard connection is realized, it can be placed stably.

[0042] The setting of the horizontal through groove 9 will not cause the excess grout to be discharged due to the increased sealing between the cover plate 61 and the grouting sleeve shell 7, under the action of thermal expansion, the wall body two 2 is lifted, the stability of the connection between the walls is poor, the grout stays in the vertical through groove 11 and solidifies, and the sealing effect is realized.

[0043] Through the above settings, the sealing connection device has the advantages of simple structure, effectively increased sealing by the sharp part 63, and improved sealing effect by the small contact area and large pressure.

[0044] Embodiment 2

[0045] The difference from embodiment 1 is that the middle part of the cover plate 61 is embedded and fixed with a rubber ring (5), the reinforcing steel bars 3 pass through the middle part of the rubber ring 5, and the diameter of the rubber ring 5 is smaller than the diameter of the reinforcing steel bars 3, so that the sealing is realized by the deformation of the rubber ring 5, and the advantages are that the installation of the cover plate 61 does not need to use a welding device for fixation, and the device is more flexible.
