[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3 In this embodiment of the utility model, a grouting device for structural gaps in building engineering includes an upper connecting pipe 1. The bottom of the outer periphery of the upper connecting pipe 1 is detachably connected to a lower connecting pipe 2 via a docking mechanism. The bottom of the lower connecting pipe 2 is integrally formed with an upper connecting head 3. A deformable rubber sleeve 4 is rotatably installed on the outer periphery of the upper connecting head 3. A lower connecting head 5 is fixedly installed on the lower inner periphery of the deformable rubber sleeve 4. The upper connecting head 3 and the lower connecting head 5 are connected by threads. A one-way mechanism is installed inside the upper connecting head 3. The lower outer periphery of the lower connecting head 5 is fixedly connected to the inner wall of the deformable rubber sleeve 4.

[0019] In the embodiment, first, when grouting the structural gap generated on the building, drill holes on the wall as required, after the drilling is completed, one end of the device deformed rubber sleeve 4 is inserted into the drilled hole groove, because the outer wall of the deformed rubber sleeve 4 has a friction-increasing pattern, after insertion, the deformed rubber sleeve 4 cannot move at will, then by rotating the upper connecting pipe 1, the rotating upper connecting pipe 1 drives the lower connecting pipe 2 to rotate synchronously through the butt joint mechanism, the rotating lower connecting pipe 2 drives the upper connecting head 3 and the lower connecting head 5 to be screwed, at this time, the lower connecting head 5 cannot rotate under the restriction of the deformed rubber sleeve 4, the upper connecting head 3 rotating towards the lower connecting head 5 drives the deformed rubber sleeve 4 to expand and deform, realizing the tight insertion of the deformed rubber sleeve 4;

[0020] Then use the grouting pipe to butt joint with the input end of the upper connecting pipe 1, under the driving of the pump, the grouting raw material is grouted into the structural gap of the building through the device, in the process, the one-way mechanism is opened under pressure, realizing the grouting purpose.

[0021] Please refer to Figure 2 , the upper connecting head 3 is provided with a rotating groove with a "convex" structure rotated by ninety degrees in cross section above the outer periphery, and the inner periphery of the deformed rubber sleeve 4 is integrally formed with a rotating ring butt joint with the rotating groove.

[0022] In the embodiment, in the process of the upper connecting head 3 rotating in, because the lower half of the deformed rubber sleeve 4 cannot move, the upper connecting head 3 drives the deformed rubber sleeve 4 to expand and deform through the rotating groove and the rotating ring, effectively plugging the drilled hole.

[0023] Please refer to Figure 2 , the one-way mechanism includes a blocking ball 7 located above the channel of the upper connecting head 3, and the channel of the upper connecting head 3 is fixedly connected with a return spring 6 below the blocking ball 7.

[0024] In the embodiment, when the grouting raw material contacts the blocking ball 7 through the channel of the upper connecting head 3, the blocking ball 7 is compressed to compress the return spring 6, at this time, the channel is opened, and enters the gap, when the grouting is stopped, the return spring 6 resets to drive the blocking ball 7 to block the channel of the upper connecting head 3, thereby avoiding the occurrence of backflow phenomenon.

[0025] Please refer to Figure 2 and Figure 3 , the butt joint mechanism includes a connecting groove 8 provided on the outer periphery of the upper connecting pipe 1 and recessed inward, a connecting spring 9 is fixedly installed on one end of the inner wall of the connecting groove 8, one end of the connecting spring 9 is fixedly installed with a butt joint plate 10 penetrating to the outside of the upper connecting pipe 1, the butt joint plate 10 is semicircular in cross section at one end outside the upper connecting pipe 1, and the inner periphery of the lower connecting pipe 2 is provided with a butt joint groove 11 butt joint with the semicircular structure of the butt joint plate 10.

[0026] In the embodiment: after the grouting is finished, the upper connecting pipe 1 is moved outward by pulling, the upper connecting pipe 1 drives the synchronous movement of the butt joint plate 10, the outer periphery of the semicircular structure of the butt joint plate 10 is extruded with the inner wall of the butt joint groove 11, at this time the connecting spring 9 is compressed, until the butt joint plate 10 is completely dislocated with the butt joint groove 11, at this time the upper connecting pipe 1 can be disassembled, without hammering or cutting.

[0027] And the butt joint mechanism can effectively transmit the torque of the upper connecting pipe 1 to the lower connecting pipe 2 during the rotation of the upper connecting pipe 1.
