Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a novel sleeve grouting leak-proof sealing structure. Background Technology

[0002] With my country's economic development and the large-scale rollout of prefabricated buildings nationwide, the assembly nodes of prefabricated buildings are receiving increasing attention, especially the crucial vertical connection technology. Among these, grouting sleeve technology is the most widely used and prevalent vertical connection method. The connection of pre-embedded grouting sleeves during the fabrication of prefabricated building components is key to the reliability of vertical connections in prefabricated buildings. Since the pre-embedded section of the grouting sleeve is embedded in concrete and cannot be visually observed, the anti-leakage measures for the pre-embedded section directly affect the connection quality of the grouting sleeve.

[0003] At the end of grouting inside the sleeve, the grouting port must be sealed with a rubber plug within one second. Rapid sealing may result in the rubber plug not fitting completely with the grouting port, leaving gaps or inadequate sealing, leading to grout leakage or backflow. Completing the sealing operation within one second requires extremely high skill and reaction speed from the operator, making it prone to human error. Grout leakage will affect the grout density and reduce structural strength. Therefore, a grout leakage prevention structure is needed that can automatically seal the grouting port when the grouting pipe is pulled out, improving the sealing effect while ensuring structural strength. Utility Model Content

[0004] The purpose of this utility model is to provide a novel sleeve-type grouting leak-proof sealing structure to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a novel sleeve grouting leak-proof sealing structure, comprising:

[0006] The sleeve, the grouting pipe, and the grout outlet pipe are connected through to the lower end of the sleeve and through to the upper end of the sleeve.

[0007] The anti-leakage grouting component includes a fixed ring, circular holes, movable columns, and baffles. The fixed ring is fixed inside the grouting pipe. Four circular holes are equally spaced on the outer surface of the fixed ring. There are four movable columns, which slide through the circular holes respectively. The baffles are fixed at the ends of the movable columns.

[0008] Furthermore, a first reinforcing bar is inserted through the lower end of the sleeve, and a second reinforcing bar is inserted through the upper end of the sleeve.

[0009] Furthermore, a connecting plate is fixed to the other end of the movable column, and a spring is fixed to one side of the connecting plate.

[0010] Furthermore, the spring extends through the outer surface of the movable column and is located between the fixed ring and the connecting plate.

[0011] Furthermore, a blocking block is fixed on one side of the connecting plate, and the blocking block is conical, with the blocking block corresponding to the internal hole of the grouting pipe.

[0012] Furthermore, it also includes a sealing assembly, which includes a sealing block, a sealing groove, a mounting groove, and a movable groove. The sealing block is engaged at the upper end of the sleeve, the sealing groove is engaged at the upper end of the outer surface of the sleeve, the mounting groove is opened inside the sealing block, and the movable groove is opened on both sides of the sealing block, and the movable groove and the mounting groove are interconnected.

[0013] Furthermore, a sealing ring is placed inside the mounting groove, a connecting block runs through the movable groove, and a push plate is fixed on one side of the connecting block, with the push plate in contact with the sealing ring.

[0014] This utility model has the following beneficial effects:

[0015] This utility model relates to a sleeve, grouting pipe, grout outlet pipe, first reinforcing bar, second reinforcing bar, and anti-leakage grouting component. During grouting, simply insert the grouting pipe into the sleeve, and the grouting pipe will push the plug backward, causing the movable column to retract within the circular hole. This compresses the spring, opening the hole in the grouting pipe and allowing grout to enter the sleeve. After grouting is completed, the grouting pipe is pulled out. Under the elastic force of the spring, the spring will quickly return to its original deformation, causing the connecting plate to move to the opposite side, moving the movable column out of the circular hole and causing the plug to block the hole in the grouting pipe. The automatic opening and closing design of the plug driven by the spring eliminates the need for manual operation, improving construction efficiency, preventing grout leakage, and ensuring grouting quality.

[0025] 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.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this utility model is a novel sleeve grouting leak-proof sealing structure, comprising:

[0028] Sleeve 11, grouting pipe 12 and grout outlet pipe 13, grouting pipe 12 is connected to the lower end of sleeve 11, grout outlet pipe 13 is connected to the upper end of sleeve 11, the lower end of sleeve 11 is penetrated by a first steel bar 14, and the upper end of sleeve 11 is penetrated by a second steel bar 15.

[0029] The sleeve 11 serves as a container for grouting, used to wrap the first reinforcing bar 14 and the second reinforcing bar 15. Grouting is injected and discharged through the grouting pipe 12 and the grout outlet pipe 13. The grouting pipe 12 is used to inject grout, which enters the sleeve 11 through the grouting pipe 12 and fills the gap between the sleeve 11 and the reinforcing bar.

[0030] The anti-leakage component includes a fixed ring 21, a circular hole 22, a movable column 23 and a baffle 24. The fixed ring 21 is fixed inside the grouting pipe 12. There are four circular holes 22, which are equally spaced on the outer surface of the fixed ring 21. There are four movable columns 23, which slide through the circular holes 22 respectively. The baffle 24 is fixed at the end of the movable column 23.

[0031] The fixed ring 21 serves as a support structure for the anti-leakage grouting component, and is used to install the movable column 23 and the spring 26. The circular hole 22 is used to insert the movable column 23, providing a sliding track for the movable column 23. The movable column 23 transmits the thrust of the grouting pipe, which pushes the baffle 24 and the plug 27 to move, thereby opening and closing the grouting pipe 12. The baffle 24 is used to limit the stroke of the movable column 23 to prevent excessive movement.

[0032] A connecting plate 25 is fixed to the other end of the movable column 23, and a spring 26 is fixed to one side of the connecting plate 25. The spring 26 passes through the outer surface of the movable column 23 and is located between the fixing ring 21 and the connecting plate 25. A blocking block 27 is fixed to one side of the connecting plate 25. The blocking block 27 is conical and corresponds to the internal hole of the grouting pipe 12.

[0033] The connecting plate 25 is used to connect the spring 26 and the plug 27. The connecting plate 25 transmits the elastic force of the spring 26, drives the plug 27 to reset, and simultaneously drives the movable column 23 to move synchronously. The spring 26 provides elastic force, drives the movable column 23 and the plug 27 to reset, realizing the automatic closing of the grouting pipe 12. Under the elastic force of the spring 26, the plug 27 blocks the hole of the grouting pipe 12 to prevent grout leakage; it is pushed open when the grouting pipe is inserted, allowing the grout to pass through.

[0034] Working principle:

[0035] During grouting, simply insert the grouting pipe into the grouting pipe 12. The grouting pipe pushes the block 27 backward, causing the movable column 23 to retract into the circular hole 22, compressing the spring 26, opening the hole of the grouting pipe 12, and allowing the grout to enter the sleeve 11. After grouting is completed, the grouting pipe is pulled out. Under the elastic force of the spring 26, the spring 26 will quickly recover its deformation, driving the connecting plate 25 to move to the opposite side, causing the movable column 23 to move out of the circular hole 22, and causing the block 27 to block the hole of the grouting pipe 12.

[0036] This step utilizes a design where the spring 26 drives the block 27 to open and close automatically, eliminating the need for manual operation, improving construction efficiency, preventing grout leakage, and ensuring grouting quality.

[0037] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The sealing assembly includes a sealing block 31, a sealing groove 32, a mounting groove 33, and a movable groove 34. The sealing block 31 is clamped at the upper end of the sleeve 11, the sealing groove 32 is clamped at the upper end of the outer surface of the sleeve 11, the mounting groove 33 is opened inside the sealing block 31, and the movable groove 34 is opened on both sides of the sealing block 31, and the movable groove 34 and the mounting groove 33 are interconnected. A sealing ring 35 is placed inside the mounting groove 33, and a connecting block 36 passes through the movable groove 34. A push plate 37 is fixed on one side of the connecting block 36, and the push plate 37 contacts the sealing ring 35.

[0039] The sealing block 31 is snapped onto the upper end of the sleeve 11, serving as the main structure of the sealing assembly for fixing and supporting other components. The sealing groove 32 cooperates with the sealing ring 35 to form a seal on the outer surface of the second reinforcing bar 15. The mounting groove 33 is used to place the sealing ring 35. The movable groove 34 provides a movement channel for the connecting block 36, enabling it to push the push plate 37 and the sealing ring 35. Under the pressure of the push plate 37, the sealing ring 35 is tightly pressed against the outer surface of the sleeve 11 to prevent concrete leakage. The connecting block 36 transmits concrete pressure to the push plate 37, pushing the sealing ring 35 to adhere to the outer surface of the sleeve 11.

[0040] Working principle:

[0041] After inserting the second reinforcing bar 15 into the sleeve 11, concrete is then injected into the precast mold. The concrete will push the connecting block 36 inward, causing the connecting block 36 to drive the push plate 37 to squeeze towards the center, so that the sealing ring 35 is tightly attached to the second reinforcing bar 15.

[0042] This step involves using concrete pressure to drive the connecting block 36 and push plate 37 to compress the sealing ring 35, thereby compensating for gaps and preventing grout leakage.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
