Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to an assembled prefabricated interior wall visual grouting device. Background Art

[0002] With the development of modern construction technology, prefabricated components have become an important part of building construction. The use of prefabricated components not only improves construction efficiency, but also reduces the impact of on-site construction on the environment. However, the connection and fixation of prefabricated components is one of the key steps to ensure their performance. Among them, sleeve grouting is a commonly used connection method, and its quality directly affects the stability and durability of prefabricated components.

[0003] In this regard, the patent document with publication number CN114635569B discloses a prefabricated and assembled building grouting device. The device includes a grouting cylinder, one end of which is slidably plugged with a piston rod, the other end of which is penetrated and plugged with a slurry outlet pipe, a plugging device is provided at the top of the grouting cylinder, and an adjusting device is provided on the side of the plugging device close to the piston rod. During grouting, the present invention only requires one operator to hold the grouting cylinder and inject concrete slurry into the grouting hole at the bottom through the first sealing tube. When the concrete slurry flows out through the second sealing tube, the grouting is stopped and the grouting cylinder is withdrawn. At this time, the first sealing plate closes the first sealing tube under the action of the first spring, and the second sealing plate cooperates with the third sealing plate under the action of the magnetic pull rod to close the second sealing tube, thereby preventing the concrete slurry from flowing out of the grouting hole at the top in time, ensuring sufficient concrete slurry in the grouting hole.

[0004] In this regard, the patent document with publication number CN116065853A discloses a wall crack grouting device and a method of using the same, which are applied in the technical field of wall crack grouting. By setting a moving component and a double-spraying mechanism, the double-spraying mechanism and the heat-insulating and cleaning grouting mechanism are respectively installed and carried on the top of the moving component, which can be convenient for users to push and carry uniformly, and thus convenient for the staff to use for subsequent repair of the wall cracks. Before grouting the wall cracks, the staff uses the spraying component of the double-spraying mechanism to blow high-pressure air into the wall cracks to clean the cement particles and dust inside the wall cracks, thereby achieving the goal of cleaning the cement particle residue inside the wall cracks, avoiding the problem of incomplete grouting and the existing particle residue affecting the slurry filling and bonding effect when grouting the cracks.

[0005] The traditional prefabricated component sleeve grouting process has certain limitations. For example, the filling of the slurry in the sleeve cannot be directly observed during the grouting process, resulting in incomplete grouting or voids, which affects the overall performance of the structure.

DETAILED DESCRIPTION

[0033] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0034] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0035] In the grouting construction of prefabricated interior walls, after conventional grouting, it is necessary to let it stand for a period of time before grouting again. However, during the grouting process, it is impossible to directly observe the filling situation of the slurry in the sleeve, resulting in incomplete grouting, or even too long a standing time, and the slurry solidifies, resulting in hollowing inside. In order to solve this problem, a prefabricated interior wall grouting device is proposed. The device adopts a visualized grouting pipe 11, a grouting head 12, a grouting sleeve 13 and a plugging head 15, so that the grouting process can be directly observed, thereby ensuring the fullness and density of the grouting, fundamentally solving the problem of incomplete grouting in traditional grouting methods, and improving construction efficiency and quality. In addition, the device has a wide range of applications, and is suitable for the construction of all vertical prefabricated component sleeve grouting. It is simple to operate. Through the visualized grouting process, construction personnel can intuitively monitor the grouting height and quality, and make timely adjustments to ensure that the slurry in each sleeve can reach the expected fullness and density.

[0036] Aiming at this defect, a device is proposed, and the operation steps of the device are as follows:

[0037] Combination Figure 1-Figure 10The present invention discloses an assembled prefabricated interior wall visual grouting device, comprising a grouting pipe 11, a grouting head 12 is sleeved at the top end of the grouting pipe 11, a grouting sleeve 13 is connected to the bottom end of the grouting pipe 11, the grouting pipe 11 and the grouting sleeve 13 are combined into an L shape, the insides of the grouting pipe 11 and the grouting sleeve 13 are connected, a plugging head 15 is embedded in the grouting pipe 11, a pull rod 14 is embedded in the plugging head 15, the grouting head 12 is sleeved at the top end of the grouting pipe 11 by a thread, the grouting head 12 and the plugging head 15 are fixedly connected together, and the plugging head 15 is embedded in the plugging head 15. The pull rod 14 embedded in the part is vertically downwardly set at the center position of the grouting pipe 11, and a spring 16 is arranged on the outer surface of the pull rod 14. The bottom end of the spring 16 is connected with a plugging piece 17, and the plugging piece 17 is arranged in a conical shape. The upper edge of the plugging piece 17 is attached to the bottom surface of the plugging head 15. The spring 16 is used to seal the bottom surface of the plugging head 15. The grouting pipe 11, the grouting head 12, the grouting sleeve 13 and the plugging head 15 are made of transparent materials. A slurry inlet 18 is provided on the plugging head 15, and the slurry inlet 18 is connected to the pipeline, and the slurry can be transported to the inside through the pipeline;

[0038] When grouting, firstly, the grouting pipe 11, the grouting head 12, the grouting sleeve 13, the tie rod 14 and the plugging head 15 are assembled, wherein the end of the grouting sleeve 13 is embedded in the prefabricated inner wall, and then the slurry is transported to the inside of the slurry inlet 18 through the pipeline. During the slurry transporting stage of the grouting machine, the transport generates pressure to make the tie rod 14 sink. At this time, the gap between the tie rod 14 and the plugging head 15 allows the slurry to flow into the inside of the plugging head 15. After the slurry flows into the inside of the plugging head 15, the slurry overcomes the pulling force of the spring 16 and pushes the plugging piece 17 and the plugging head 15 to separate. After the separation, the slurry flows from the bottom end of the plugging head 15 to the inside of the grouting pipe 11, and finally the slurry flows through the grouting pipe 11 to the inside of the grouting sleeve 13, and finally poured into the inner wall.

[0039] When the slurry flows into the interior of the plugging head 15, the slurry is continuously transported into the interior of the plugging head 15 by the grouting machine, so that the space inside the plugging head 15 is completely filled, so that the air inside the plugging head 15 can also be discharged. After the internal air is discharged, the slurry needs to be continuously compressed until the plugging piece 17 and the plugging head 15 are pushed to separate, and the slurry can flow into the grouting pipe 11 through the grouting port 32. If there is air in the slurry, after compression and extrusion, the density of the slurry can be made higher, so that some bubbles in the slurry can also be eliminated;

[0040] Based on this, not only can the injection of slurry be observed in real time, but the interior can also be sealed after grouting to reduce the introduction of air and reduce hollowing.

[0041] In order to further eliminate the air in the slurry, the slurry is squeezed by setting, and the slurry is extracted by negative pressure after squeezing, and the internal bubbles are eliminated by extraction to improve the quality of slurry injection. The specific operations are as follows:

[0042] The inside of the grouting pipe 11 is also embedded with a pressurizing component 2, which includes a through rod 21, which is embedded in the inside of the pull rod 14, and the through rod 21 and the pull rod 14 are slidably connected. By pulling the through rod 21, the grouting pipe 11 can be vibrated. An isolation plate 22 is embedded in the inside of the grouting pipe 11, and a positioning plate 23 is also embedded in the inside of the grouting pipe 11. Two groups of pressure pipes 24 are arranged at the bottom end of the positioning plate 23. The pressure pipes 24 are grouped in pairs, totaling four. The positioning plate 23 is arranged at the bottom end of the isolation plate 22, and the bottom surface of the positioning plate 23 is connected to the pressure pipe 24, and the bottom end of the pressure pipe 24 is connected to a sealing ring 25. A gear ring 26 is installed on the upper surface of the disk 23. Two groups of gear rings 26 are provided. The two groups of gear rings 26 are connected by a bracket. The rotation of the gear ring 26 is driven by a rotating rod 28. A pressure rod 29 is embedded in the pressure tube 24. The bottom end of the pressure tube 24 corresponds to the slurry outlet 34 opened at the bottom end of the sealing ring 25. The pressure rod 29 embedded in the pressure tube 24 is close to the inner wall of the pressure tube 24. The top of the pressure rod 29 is connected to a rack 27. The rack 27 is embedded in the pressure tube 24 and fixedly connected to the pressure rod 29. The rack 27 is slidably connected to the inside of the pressure tube 24. The rack 27 is meshed with the gear ring 26. The gear ring 26 is connected to the rotating rod 28.

[0043] The inner wall grouting slurry flows through the interior of the grouting pipe 31 through the grouting port 32 until it flows into the space at the bottom end of the sealing ring 25 and fills the interior of the grouting sleeve 13. A pressure relief component 3 is provided inside the isolation plate 22. The pressure relief component 3 includes a grouting port 32. A grouting pipe 31 is embedded in the grouting port 32. The bottom end of the grouting pipe 31 passes through the interior of the sealing ring 25 and extends to the bottom surface of the sealing ring 25. An air vent 33 is provided on the surface of the positioning plate 23. A slurry outlet 34 is provided at the bottom end of the sealing ring 25. The interior of the air vent 33 is configured to be trumpet-shaped. The top opening of the air vent 33 is large and the bottom opening is small.

[0044] After the grouting is completed, the grout is injected into the interior of the plugging head 15, and then transported to the lower half of the grouting pipe 11 through the grouting pipe 31 until it is filled into the prefabricated inner wall. At this time, the gear ring 26 is rotated by rotating the rotating rod 28. When the gear ring 26 rotates, it drives one of the racks 27 to descend. When the rack 27 descends, it drives the pressure rod 29 to descend. At this time, the slurry is squeezed, and the density inside the slurry is increased by squeezing. The gear ratios on both sides of the gear ring 26 are different. When the gear ring 26 rotates, one group of racks 27 descends and the other group of racks 27 rises. The descending process is twice the ascending process.

[0045] For example, when one set of racks 27 drops by 2 units, the other set of racks 27 only rises by one unit, so that the middle of the interior is reduced, and the slurry is squeezed under pressure to accelerate the filling of the wall interior, so that the slurry can be pressurized during the descent. When one of the racks 27 drops to the bottom, the other rack 27 rises to the top, and contacts the one-way valve provided on the pressure rod 29 through the top block on the pressure tube 24, so that the one-way valve is opened. At this time, air overflows through the one-way valve on the pressure rod 29. When rotating in the reverse direction, when the racks 27 drop by 1 unit, the other rack 27 rises by two units. The negative pressure generated at this time will attract the slurry, and thus the slurry is sucked into the interior of the pressure tube 24 through the slurry outlet 34. When one of the racks 27 drops, it drives the corresponding pressure rod 29 to drop. At this time, the slurry sucked into the interior of the pressure tube 24 will be discharged through the slurry outlet 34. Through the reciprocating circulation of the racks 27, the slurry continuously goes back and forth to the interior of the pressure tube 24, thereby improving the fluidity of the slurry inside.

[0046] As the gear ring 26 rotates in different directions, the racks 27 on both sides of the gear ring 26 are driven to rise and fall. The different rising heights and falling heights are adjusted by the gear ratio, so that the internal space can be compressed when the racks 27 are lowered. In addition, the slurry can be driven to flow, so that the slurry flows to eliminate hollows. As the air inside is discharged after the flow, the slurry is continuously transported through the grouting pipe 31 to ensure that the prefabricated inner wall is completely filled.

[0047] During the operation of pressurizing the interior, based on the visual design, the internal situation can be better observed, and the gear ring 26 can be controlled to rotate according to the specific situation to pressurize the interior, and the operation flexibility is also higher.
