[0015] A method for using an assembled vertical prefabricated component sleeve visual grouting assembly mainly comprises the following steps:

[0016] Step A: When in use, a sleeve is pre-set in the component, and a steel bar is inserted through the sleeve to improve the strength of the structure, so that the two components are connected as a whole, wherein the overflow port and the grouting port penetrate the component and extend to the side surface of the prefabricated component, which is convenient for the subsequent grouting operation, and then an L-shaped pipe is inserted at one end of the overflow port and limited by a connecting sleeve. When the grouting operation is performed, the grouting pipe is inserted into the grouting port, and the injected slurry fills the sleeve and then overflows through the overflow port. The overflowed slurry enters the interior of the L-shaped pipe. When the slurry enters the L-shaped pipe, the staff can know the grouting amount state of the slurry by observing the slurry in the L-shaped pipe;

[0017] Step B: After the slurry enters the L-shaped tube, the slurry squeezes the sealing piece set in the L-shaped tube to move and displace the sealing piece. In this process, the air that enters the L-shaped tube during the grouting process can be exhausted. During the rising process of the sealing piece, the disc is driven to move synchronously, thereby facilitating the squeezing of the pre-stored air, causing the second airbag and the third airbag to expand. When the slurry squeezing piston is displaced to the inner wall at the top of the L-shaped tube, the grouting tube at the grouting port is pulled out, and the grouting port is blocked with a sealing plug to complete the grouting operation.

[0018] Compared with the prior art, the present invention provides a prefabricated vertical prefabricated component sleeve visual grouting assembly, which has the following beneficial effects:

[0019] 1. This kind of assembled vertical prefabricated component sleeve visual grouting assembly can be plugged into one end of the overflow port through the provided L-shaped tube. When the slurry injected into the sleeve enters the L-shaped tube, it is convenient for the staff to observe the state of the injected slurry in real time through the L-shaped tube. At the same time, the air entering the L-shaped tube can be discharged through the sealing piece provided on the L-shaped tube to prevent bubbles from being trapped inside the sleeve to form bubbles, which will affect the density and strength of the grouting.

[0020] 2. This kind of assembled vertical prefabricated component sleeve visualized grouting assembly drives the disc to move upward during the rising process of the sealing part, thereby facilitating the squeezing of the pre-placed first air bag, so that the internal air is transported to the second air bag and the diverter pipe, thereby effectively improving the sealing performance of one end of the L-shaped pipe and preventing the slurry from escaping from the joint between the L-shaped pipe and the connecting sleeve.

[0021] 3. This kind of assembled vertical prefabricated component sleeve visualized grouting assembly, when the trapezoidal block moves upward, can also drive the arc plate to move upward synchronously, thereby squeezing the limit ring to shift horizontally, and horizontally supporting the side of the second airbag, thereby further improving the sealing effect of the L-shaped tube, and at the same time playing a good role in correcting deformation.

[0022] The parts not involved in the device are the same as the prior art or can be implemented by the prior art. The L-shaped tube provided in the present invention can be used to observe the amount of slurry injected into the sleeve, thereby realizing the visual operation of the grouting process and improving the accuracy of slurry pouring. During the grouting process, the air entering the L-shaped tube during the grouting process can be exhausted by the setting of the plugging piece to avoid bubbles being trapped inside the sleeve and forming bubbles, which affect the density and strength of the grouting. At the same time, the power of the plugging piece moving upward is used to inflate the joint between the L-shaped tube and the connecting sleeve, thereby improving the sealing performance of the structure and preventing the slurry from leaking out.

[0036] Reference Figure 1-Figure 9 , an assembled vertical prefabricated component sleeve visual grouting assembly, comprising a sleeve 1 preset in the component, an overflow port 11 is arranged on one side of the sleeve 1, a grouting port 12 is arranged on the side of the overflow port 11 below the overflow port 11, a steel bar 13 is arranged inside the sleeve 1, a connecting sleeve 14 is sleeved on the surface of the overflow port 11, an L-shaped tube 2 is sleeved on one end of the connecting sleeve 14, a sealing ring 21 is fixed on the outer wall of one end of the L-shaped tube 2, and convex patterns 22 distributed at equal intervals are arranged on the surface of the sealing ring 21; a disc 32 is arranged above the L-shaped tube 2, and a plugging piece is arranged at one end of the disc 32, which is used to discharge the air in the L-shaped tube 2 when the overflowed slurry squeezes the plugging piece to move; a second airbag 57 and a third airbag 59 are arranged on the outer wall surface of one end of the L-shaped tube 2, and when the plugging piece moves, the pre-stored air is transported to the second airbag 57 and the third airbag 59 to expand to seal and limit the joint between the L-shaped tube 2 and the connecting sleeve 14.

[0037] When in use, the sleeve 1 is pre-set in the component, and the steel bar 13 is inserted through the sleeve 1 to improve the strength of the structure, so that the two components are connected as a whole, wherein the overflow port 11 and the grouting port 12 extend through the component to the outer surface of the prefabricated component, which is convenient for the subsequent grouting operation, and then the L-shaped tube 2 is inserted at one end of the overflow port 11 and a limit is set through the connecting sleeve 14. When the grouting operation is performed, the grouting tube is inserted into the grouting port 12, and the injected slurry fills the sleeve 1 and then overflows through the overflow port 11. The overflowed slurry enters the interior of the L-shaped tube 2, wherein the L-shaped tube 2 is made of transparent plastic tube material. When the slurry enters the L-shaped tube 2, the staff can know the slurry by observing the slurry in the L-shaped tube 2. The filling amount state can be visualized for improved accuracy of slurry filling. When the slurry enters the L-shaped tube 2, the sealing member arranged in the L-shaped tube 2 is squeezed by the slurry to move the sealing member. In this process, the air entering the L-shaped tube 2 during the grouting process can be exhausted to prevent air from entering the slurry in the sleeve 1 and causing voids and leakage. During the rising process of the sealing member, the disc 32 is driven to move synchronously, thereby facilitating the squeezing of the pre-stored air, causing the second airbag 57 and the third airbag 59 to expand, thereby improving the sealing performance of the joint between the L-shaped tube 2 and the connecting sleeve 14, preventing the injected slurry from leaking out of the joint, and at the same time correcting the sealing components to extend their service life.

[0038] In a preferred embodiment, referring to Figure 2 , Figure 3 , Figure 4 and Figure 7The blocking member includes a piston 33 slidably connected to the inner wall of the L-shaped tube 2, a lifting rod 31 is fixedly connected to the top of the piston 33, the lifting rod 31 is slidably connected in the L-shaped tube 2, an extrusion spring 34 is fixedly connected to the inner wall of the L-shaped tube 2, the extrusion spring 34 is sleeved on the surface of the lifting rod 31, and the other end of the lifting rod 31 is fixedly connected to the disc 32, an exhaust channel 41 is opened inside the lifting rod 31, the disc 32 and the piston 33, a first chamber 44 is opened inside the piston 33, and the surface of the piston 33 is opened. A second chamber 45 is provided, and the first chamber 44, the second chamber 45 and the exhaust channel 41 are connected. A moving block 46 is slidably connected inside the first chamber 44, and a return spring 47 is fixedly connected to one side of the moving block 46. The end of the return spring 47 is fixedly connected to the piston 33. A pressing block 48 is fixedly connected to the top of the L-shaped tube 2, and the pressing block 48 is adapted to the second chamber 45. A retaining ring 42 is fixed to the top surface of the disc 32, and a sealing cover 43 is provided at the axis of the retaining ring 42 located at the outlet end of the exhaust channel 41.

[0039] When the poured slurry overflows from the overflow port 11 into the L-shaped tube 2, the overflowing slurry contacts the bottom surface of the piston 33 to squeeze the piston 33 to move inside the L-shaped tube 2. When the piston 33 moves to the top of the L-shaped tube 2, it stops moving at a limited position to prevent the poured slurry from running out. At the same time, since the L-shaped tube 2 is made of transparent plastic, it is convenient to visualize the fullness of the poured slurry. During the pouring process, since one end of the lifting rod 31 is fixedly connected to the disc 32, when the piston 33 moves, the disc 32 moves synchronously. The shape of the disc 32 is larger than that of the piston 33, and the disc 32 moves upward during the pouring process, which makes it more convenient for the staff to observe the state of the poured slurry, and the slurry delivery can be stopped in time to prevent leakage from the grouting port 12, thereby optimizing the visualization state of the L-shaped tube 2 and making it more eye-catching.

[0040] When the slurry poured in the sleeve 1 overflows from the overflow port 11, the internal air enters the interior of the L-shaped tube 2 in advance. Since an exhaust channel 41 is provided at the piston 33, the air entering the L-shaped tube 2 can be discharged through the exhaust channel 41 and then transported to the top of the disc 32. This prevents air from flowing back into the slurry or into the interior of the sleeve 1, causing local voids and unfilled honeycombs, which affects the construction quality. The L-shaped tube 2 has an exhaust effect when performing visual operations on the poured slurry.

[0041] It should be noted that, although the exhaust channel 41 can exhaust the air in the sleeve 1, during the pouring process, when the slurry contacts the bottom of the piston 33, a small part of the slurry will be discharged through the exhaust channel 41. However, since the diameter of the exhaust channel 41 is small, the part of the slurry that escapes flows through the exhaust port to the retaining ring 42 for storage and collection, so that no waste of slurry is caused.

[0042] When the piston 33 moves upward and approaches the top inner wall of the L-shaped tube 2, the pressing block 48 is inserted into the interior of the second chamber 45 and contacts the moving block 46. The pressing block 48 is adapted to the moving block 46, squeezing the moving block 46 to move horizontally. The moving block 46 is used to block the exhaust channel 41 to prevent the slurry in the L-shaped tube 2 from continuously running out, thereby achieving a good limiting effect.

[0043] In a preferred embodiment, reference is made to Figure 2 , Figure 4 , Figure 5 and Figure 6 The bottom of the disc 32 is located on one side of the lifting rod 31 and is fixedly connected to a connecting rod 51. The end of the connecting rod 51 is fixedly connected to a trapezoidal block 52. A first airbag 53 is arranged obliquely above the trapezoidal block 52. The first airbag 53 is fixed on the outer wall of the L-shaped tube 2. A reset member is arranged in the first airbag 53. The reset member includes a limit plate 54 fixed on the inner wall of the first airbag 53. A telescopic spring 55 is fixedly connected between the two limit plates 54. The outer wall of the first airbag 53 is rounded. An air inlet is arranged on the surface of the first airbag 53. A sealing cap is arranged at the air inlet. An air supply pipe 56 is fixedly connected to the top of the first airbag 53. One end of the air supply pipe 56 passes through the inner wall of the L-shaped tube 2 and is fixedly connected to the second airbag 57. A shunt pipe 58 is fixedly connected to one end of the air supply pipe 56. The end of the shunt pipe 58 is fixedly connected to the third airbag 59. The third airbag 59 is arranged in the sealing ring 21.

[0044] When the disc 32 moves, it can drive the connecting rod 51 to move synchronously, and then drive the trapezoidal block 52 at one end of the connecting rod 51 to move, wherein the trapezoidal block 52 is a trapezoidal shape, and when moving upward, one side of the inclined surface contacts the surface of the first airbag 53 to squeeze the first airbag 53, so that the air in the first airbag 53 is transported to the second airbag 57 through the air delivery pipe 56, and the second airbag 57 expands, thereby supporting and squeezing the concave inclined surface of one side of the sealing ring 21. On the other hand, part of the air is transported to the third airbag 59 through the shunt pipe 58 to make it expand, and the third airbag 59 is arranged on the sealing ring 21. The inside of the ring 21 makes the sealing ring 21 fit more closely with the inner wall of the connecting sleeve 14 to prevent loosening and falling off, thereby ensuring that the slurry in the sleeve 1 runs out from the joint, improving the sealing effect of the device, and making the device have visual operation while having good sealing performance. Compared with the traditional sealing structure, it avoids the connected parts from being squeezed and deformed during transportation, which causes the sealing to be unreliable. In addition, the sealing design of this scheme is evenly extruded to improve the stability of the device sealing. It should be understood that the second airbag 57 expands upward when it expands.

[0045] In a preferred embodiment, referring to Figure 1 , Figure 8 and Fig. 9 A fixing rod 61 is fixedly connected to the bottom of the trapezoidal block 52, and an arc-shaped plate 62 is fixedly connected to the bottom of the fixing rod 61. A limiting ring 63 is arranged on one side of the arc-shaped plate 62. A sliding seat 64 is fixedly connected to the bottom of the limiting ring 63. The sliding seat 64 is slidably connected to a sliding rail 65. The sliding rail 65 is fixed on the outer wall of the L-shaped tube 2. A fixing ring 67 is fixed at one end of the sliding rail 65. The fixing ring 67 is fixed on the outer wall of the L-shaped tube 2. A limiting spring 66 is fixedly connected between the fixing ring 67 and the limiting ring 63.

[0046] By adopting the above scheme, when the trapezoidal block 52 moves upward, it drives the arc plate 62 to move upward synchronously, wherein one end of the arc plate 62 is provided with an inclined surface, which is adapted to one side surface of the limit ring 63. As the arc plate 62 moves, the limit ring 63 is squeezed and horizontally displaced, so that one side surface of the limit ring 63 is displaced toward the second airbag 57, thereby providing side support and positioning for the second airbag 57 and the sealing ring 21. The diameter of the limit ring 63 is the same as the diameter of the connecting sleeve 14, and a secondary seal is performed on the joint between the connecting sleeve 14 and the L-shaped tube 2, which has a good limiting support effect, and has a good corrective effect on the sealing ring 21 and the second airbag 57, preventing large deformation during inflation. The setting of the slide seat 64 and the slide rail 65 improves the smoothness and stability of the movement of the limit ring 63, and plays a role in movement limitation.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

A method for using a prefabricated vertical prefabricated component sleeve visual grouting assembly, according to claim 4, characterized in that: The main steps include: Step A: When in use, the sleeve (1) is pre-arranged in the component, and the steel bar (13) is inserted through the sleeve (1) to improve the strength of the structure so that the two components are connected as a whole, wherein the overflow port (11) and the grouting port (12) penetrate the component and extend to the side surface of the prefabricated component to facilitate the subsequent grouting operation, and then the L-shaped pipe (2) is inserted into one end of the overflow port (11) and limited by the connecting sleeve (14). When the grouting operation is performed, the grouting pipe is inserted into the grouting port (12), and the injected slurry fills the sleeve (1) and then overflows through the overflow port (11). The overflowed slurry enters the interior of the L-shaped pipe (2). When the slurry enters the L-shaped pipe (2), the staff can know the injection amount state of the slurry by observing the slurry in the L-shaped pipe (2); Step B: After the slurry enters the L-shaped tube (2), the slurry squeezes the sealing member provided in the L-shaped tube (2), causing the sealing member to move and displace. During this process, the air that enters the L-shaped tube (2) during the grouting process can be exhausted. During the rising process of the sealing member, the disc (32) is driven to move synchronously, thereby facilitating the squeezing of the pre-stored air, causing the second airbag (57) and the third airbag (59) to expand. When the slurry squeezing piston (33) moves to the inner wall at the top of the L-shaped tube (2), the grouting tube at the grouting port (12) is pulled out, and the grouting port (12) is blocked with a sealing plug, thereby completing the grouting operation.
