The hollow pressing block is pushed into the connecting pipe to fix the pipeline, and the movement of the connecting plate is controlled by changing the air pressure in the hollow pressing block to form a seal to prevent mortar leakage. Overall, the utility model can be quickly installed and disassembled, improving the grouting efficiency.

[0004] Although the above patent can quickly disassemble the pipeline, there are still some problems. The pipeline will vibrate during the grouting process, and continuous vibration may cause loosening at the connection between the connecting pipe and the pipeline, resulting in leakage. For this reason, the utility model provides a pipeline connection structure for grouting of prefabricated buildings. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a pipeline connection structure for grouting of prefabricated buildings, which solves the problem that the pipeline will vibrate during the grouting process, and continuous vibration may cause loosening at the connection between the connecting pipe and the pipeline, resulting in leakage.

[0014] Beneficial effects

[0015] The utility model provides a pipeline connection structure for grouting in prefabricated buildings. Compared with the prior art, the following beneficial effects are achieved:

[0016] (1). For this pipeline connection structure for grouting in prefabricated buildings, after the first connection pipe and the second connection pipe are docked, in order to improve the stability between the first connection pipe and the second connection pipe, the sealing pipe sleeve can be rotated. During the rotation of the sealing pipe sleeve, the pressing ring is driven to move towards the four sliding rods. Since one side of the outer wall of the pressing ring is provided with a bevel, the pressing ring will gradually press the sliding rods during the movement. After being pressed, the sliding rods will drive the arc-shaped pressing plates to move downward, so that the arc-shaped pressing plates press the first connection pipe. The arc-shaped pressing plates can provide an additional clamping force, making the connection between the first connection pipe and the second connection pipe more firm, being able to better resist the vibration generated during grouting, and further reducing the leakage at the pipeline connection caused by vibration between the pipelines.

[0017] (2) For the pipe connection structure for grouting of prefabricated buildings, when the sealing sleeve rotates, one end of its outer wall gradually approaches the sealing plate until the sealing sleeve is in close contact with the sealing ring. When leakage occurs between the first connecting pipe and the second connecting pipe, the sealing sleeve and the sealing plate can block the leaked grout, preventing the grout from leaking directly out, thus improving the sealing performance during pipe grouting.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The present invention provides two technical solutions:

[0026] Figures 1-5 The first embodiment is shown: A pipe connection structure for grouting of prefabricated buildings includes a first connection component 1, and a second connection component 2 is arranged on one side of the outer wall of the first connection component 1;

[0027] The first connection component 1 includes a first connecting pipe 11. An external thread 12 is provided on the outer wall of the first connecting pipe 11, enabling the first connecting pipe 11 to be threadedly connected to the connecting pipe sleeve 22, so that the first connecting pipe 11 and the second connecting pipe 21 are docked for grouting.

[0028] The second connection component 2 includes a second connecting pipe 21. One end of the outer wall of the second connecting pipe 21 is fixedly installed with a connecting pipe sleeve 22. A fixing sleeve 26 is fixedly installed on the outer wall of the connecting pipe sleeve 22. A second external thread 23 is provided on the outer wall of the connecting pipe sleeve 22. A sealing pipe sleeve 24 is threadedly connected to the outer wall of the connecting pipe sleeve 22, enabling the sealing pipe sleeve 24 to rotate and move on the surface of the connecting pipe sleeve 22.

[0029] Four sliding rods 27 slidably penetrate through the outer wall of the fixing sleeve 26. Arc-shaped pressing plates 210 are fixedly installed at the bottom ends of the four sliding rods 27. Springs 28 are sleeved on the outer walls of the four sliding rods 27. One ends of the four springs 28 are fixedly connected to the inner wall of the fixing sleeve 26, and the other ends of the four springs 28 are respectively fixedly connected to the four arc-shaped pressing plates 210. When the sliding rods 27 are squeezed, they will drive the arc-shaped pressing plates 210 to move downward. When the sliding rods 27 stop being squeezed, the springs 28 can reset the arc-shaped pressing plates 210.

[0030] Figures 1-5 The second implementation mode is shown. The main difference from the first implementation mode is that: an extrusion ring 25 is fixedly installed on the inner wall of the sealing pipe sleeve 24. One side of the outer wall of the extrusion ring 25 and the top ends of the four sliding rods 27 are provided with bevels at a certain angle. Ball bearings 29 are rotatably arranged at the top ends of the four sliding rods 27. Since the extrusion ring 25 is provided with a bevel, the extrusion ring 25 will squeeze the top ends of the sliding rods 27 during the moving process. At the same time, ball bearings 29 are provided at the top ends of the sliding rods 27, which will reduce the friction between the extrusion ring 25 and the top ends of the sliding rods 27 during the rotation process.

[0031] A sealing plate 13 is fixedly installed on the outer wall of the first connecting pipe 11. A sealing ring 14 is fixedly installed on one side of the outer wall of the sealing plate 13. The sealing ring 14 can be made of rubber material. When the sealing pipe sleeve 24 squeezes the sealing ring 14, the sealing performance between the sealing pipe sleeve 24 and the sealing plate 13 is improved.

[0032] The outer wall of the first connecting pipe 11 matches the inner wall of the connecting pipe sleeve 22, and the first connecting pipe 11 is threadedly connected to the connecting pipe sleeve 22.

[0033] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0034] During operation, when it is necessary to connect the first connecting pipe 11 and the second connecting pipe 21, first insert the first connecting pipe 11 into the interior of the connecting pipe sleeve 22, and then rotate the first connecting pipe 11 so that the first connecting pipe 11 and the second connecting pipe 21 are butted. After the first connecting pipe 11 and the second connecting pipe 21 are butted, in order to improve the stability between the first connecting pipe 11 and the second connecting pipe 21, the sealing pipe sleeve 24 can be rotated. During the rotation of the sealing pipe sleeve 24, the pressing ring 25 is driven to move towards the four sliding rods 27. Since one side of the outer wall of the pressing ring 25 is provided with an inclined edge, the pressing ring 25 will gradually press the sliding rods 27 during the movement. After being pressed, the sliding rods 27 will drive the arc-shaped pressing plate 210 to move downward, so that the arc-shaped pressing plate 210 presses the first connecting pipe 11. The arc-shaped pressing plate 210 can provide an additional clamping force, making the connection between the first connecting pipe 11 and the second connecting pipe 21 more firm, and being able to better resist the vibration generated during grouting, thereby reducing the leakage at the pipe connection caused by vibration between the pipes. When the sealing pipe sleeve 24 is rotating, one end of the outer wall will gradually approach the sealing plate 13 until the sealing pipe sleeve 24 is in close contact with the sealing ring 14. When leakage occurs between the first connecting pipe 11 and the second connecting pipe 21, the sealing pipe sleeve 24 and the sealing plate 13 can block the leaked grouting, preventing the grouting from leaking directly, and improving the sealing performance during pipe grouting.
