[0002] In prefabricated concrete structures, the installation and connection of vertical prefabricated concrete components often use grouting joints to connect the vertical steel bars of the components. The function of the grouting material plugger is to block the duct where the grouting material flows out from the slurry holes on the surface of the component during grouting construction. The existing plugger is generally composed of a closing plate, a sealing column and a rubber sleeve. When sealing, the sealing column with a fixed rubber sleeve needs to be inserted into the duct so that the rubber sleeve is in sealing contact with the hole wall of the duct to achieve the sealing effect.

[0003] The existing channels to be blocked have different apertures, and the rubber sleeve is easily deformed due to long-term contact with the grouting slurry, which affects the blocking effect. At this time, the rubber sleeve needs to be replaced, but the rubber sleeve and the blocking column are generally fixed with adhesives, and the disassembly and assembly steps are relatively cumbersome.

[0058] Example 1

[0059] Reference Figures 1-8This embodiment provides a grouting material plug for a steel bar grouting joint, which is characterized in that it includes: a closing plate 1, a closing column 2 and a rubber sleeve 3. For the convenience of description, it is assumed that the closing plate 1 has a first side surface and a second side surface, the closing column 2 has a first end and a second end, and the rubber sleeve 3 has a first end and a second end.

[0060] The first end surface of the blocking column 2 is fixedly connected to the first side surface of the closing plate 1, and the rubber sleeve 3 is sleeved on the blocking column 2 and connected to the blocking column 2 through a locking assembly;

[0061] The surface of the blocking column 2 is provided with multiple groups of locking components for locking the rubber sleeve 3. The locking components include a support plate 4 and a locking block 6 fixedly installed on the surface of the support plate 4 through a support rod 5. The outer side surface of the blocking column 2 is circularly provided with multiple mounting grooves 7. The support plate 4 has a first end and a second end. The first end of the support plate 4 is arranged in the mounting groove 7 and is close to the second end of the blocking column 2. The outer side surface of the support plate 4 is fixedly connected to the locking block 6 through the support rod 5.

[0062] The inner side of the rubber sleeve 3 is provided with a locking groove 8 corresponding to the mounting groove 7, that is, a plurality of locking grooves 8 are provided around the circumference for receiving the plurality of locking blocks 6. The locking blocks 6 are disposed within the mounting groove 7 and move into the locking grooves 8 when locked. This is achieved by providing a drive assembly, which is disposed within the mounting groove 7 and fixedly connected to the locking blocks 6 to drive the locking blocks 6 to move into the locking grooves 8. The drive end of the drive assembly passes through the closing plate 1 and is disposed on the second side surface of the closing plate 1.

[0063] The surface of the closing plate 1 is circumferentially provided with a plurality of openings 9 corresponding to the mounting grooves 7; the mounting rod 10 is fixedly disposed in the opening 9, and the central axis of the mounting rod 10 is disposed along the radial direction of the closing plate 1;

[0064] The second end of the support plate 4 passes through the through opening 9 and is arranged on the outer side of the second side of the closing plate 1. The support plate 4 is provided with a through hole adapted to the mounting rod 10. The support plate 4 is slidably connected to the mounting rod 10.

[0065] The telescopic spring 11 is sleeved on the mounting rod 10 , and two ends of the telescopic spring 11 are fixedly connected to the outer side surface of the support plate 4 and the inner wall of the through opening 9 respectively.

[0066] The locking component includes two working states:

[0067] When in the unlocked state, the outer side surface of the locking block 6 does not exceed the outer circumferential surface of the blocking column 2, that is, the rubber sleeve 3 can be normally put on the blocking column 2, and the rubber sleeve 3 can be separated from the blocking column 2.

[0068] When in the locked state, the outer side surface of the locking block 6 exceeds the outer circumferential surface of the blocking column 2. Here, the locking block 6 is inserted into the locking groove 8 of the rubber sleeve 3, thereby fixing the blocking column 2 and the rubber sleeve 3.

[0069] In this embodiment, in order to maintain installation stability, the number of installation grooves 7 is set to multiple and distributed in a ring shape around the central axis of the blocking column 2. The installation grooves 7 are arranged along the central axis of the blocking column 2, and the number of locking grooves 8, the number of installation grooves 7 and the number of locking blocks 6 are all equal.

[0070] In order to lock the position of the support plate 4, the driving assembly in this embodiment further includes a clamping component, and the second end of the support plate 4 is connected to the closing plate 1 through the clamping component;

[0071] The clamping component includes an inclined plate 14 , a pressing plate 13 , an inserting plate 16 , a first spring rod 12 and a second spring rod 15 .

[0072] The first end of the inclined plate 14 is fixedly connected to the second end of the support plate 4, and the distance from the second end of the inclined plate 14 to the center of the closing plate 1 is greater than the distance from the first end of the inclined plate 14 to the center of the closing plate 1; the pressure plate 13 is disposed on the second side surface of the closing plate 1, and the circumference of the pressure plate 13 abuts against the inclined surface of the inclined plate 14; the first end of the first spring rod 12 is fixedly connected to the second side surface of the closing plate 1, and the second end of the first spring rod 12 is fixedly connected to the pressure plate 13;

[0073] The plug-in board 16 has a first end and a second end. The first end of the plug-in board 16 is fixedly connected to the pressure plate 13. The closing plate 1 is provided with a slot 17 corresponding to the second end of the plug-in board 16. The second end of the plug-in board 16 is provided with a card interface 18.

[0074] The second spring rod 15 is fixedly arranged in the slot 17, and when in the original length state, the telescopic end of the second spring rod 15 is inserted into the card interface 18; a pull plate 19 is fixedly sleeved on the second spring rod 15, and the surface of the pull plate 19 is provided with anti-slip grooves.

[0075] When in the locked state, the first spring rod 12 applies a force to the pressing disk 13 away from the closing disk, and the telescopic end of the second spring rod 15 is inserted into the card interface 18 .

[0076] Here's how it works:

[0077] Removing the rubber sleeve 3: When the aperture of the blocked channel is large, the outer wall of the rubber sleeve 3 cannot be in sealing contact with the hole wall of the channel, or the rubber sleeve 3 is deformed due to long-term contact with the grouting slurry, and the rubber sleeve 3 needs to be replaced, first pull the pull plate 19 to control the contraction of the second spring rod 15, so that the telescopic end of the second spring rod 15 is moved out from the card interface 1818. At this time, under the elastic potential energy of the first spring rod 12, the pressure plate 13 will be quickly reset. During the reset process, the pressure on the inclined plate 14 will be released, and the multiple support plates 4 will quickly move back to the installation groove 7 from the multiple locking grooves 8 with the multiple locking blocks 6. At this time, the installation between the rubber sleeve 3 and the blocking column 2 is released, and the rubber sleeve 3 can be removed from the blocking column 2.

[0078] Install a new rubber sleeve 3: Remove the original rubber sleeve 3, and put the new rubber sleeve 3 on the blocking column 2, and make the multiple locking grooves 8 correspond to the multiple installation grooves 7 respectively. By pulling the pull plate 19 to control the contraction of the second spring rod 15, and then push the pressure plate 13 to move toward the direction close to the closing plate 1, the first spring rod 12 will contract, and the pressure plate 13 will also slide in contact with the inclined surface of the inclined plate 14. Under the pressure of the pressure plate 13, the multiple inclined plates 14 will move with the support plate 4, and the multiple telescopic springs 11 will also contract at this time.

[0079] During the movement, multiple locking blocks 6 will respectively enter multiple locking grooves 8 to form a lock, and the rubber sleeve 3 cannot be removed from the blocking column 2 at this time. At this time, the insert plate 16 will also be inserted into the slot 17, and the card interface 18 will correspond to the telescopic end position of the second spring rod 15 respectively. Then release the pull plate 19, and the telescopic end of the second spring rod 15 will quickly reset under the action of its own elastic potential energy and pass through the card interface 18 to form a card connection. At this time, the first spring rod 12 is locked, and the pressure plate 13 is released. The pressure plate 13 will not reset under the elastic potential energy of the first spring rod 12. At this time, the installation between the rubber sleeve 3 and the blocking column 2 is completed, which is convenient and quick, avoids the cumbersome steps of using glue, and improves the work efficiency of replacing the rubber sleeve 3.

[0080] In addition, in order to increase the connection stability between the pressure plate 13 and the closing plate 1, the number of the inserting plate 16, the second spring rod 15, and the slot 17 are all multiple and distributed in a ring shape along the central axis of the closing plate 1;

[0081] Example 2

[0082] The occluder also includes an auxiliary fixing assembly, which is arranged on the outer circumferential surface of the closing plate 1; the auxiliary fixing assembly is used to assist in fixing the closing plate 1 and the grouting joint. In actual use, the entire rubber sleeve 3 is first inserted into the grouting joint, and then the auxiliary fixing assembly is used to apply force to the grouting joint to clamp the grouting joint.

[0083] The auxiliary fixing assembly includes a threaded rod 20 , a sliding rod 21 , a limiting rod 23 and a clamping plate 22 .

[0084] The first end of the threaded rod 20 is rotatably connected to the outer circumferential surface of the closing plate 1, and the central axis of the threaded rod 20 is set along the radius of the closing plate 1; the first end of the sliding rod 21 is vertically threadedly connected to the second end of the threaded rod 20, and the central axis of the sliding rod 21 is set along the central axis of the blocking column 2; the clamping plate 22 is fixedly connected to the second end of the sliding rod 21, and when in an auxiliary fixed state, the clamping plate 22 applies an inward force to the outer side surface of the grouting joint; the limiting rod 23 is arranged parallel to the threaded rod 20, and the first end of the limiting rod 23 is fixedly connected to the closing plate 1, and the first end of the sliding rod 21 is slidably connected to the limiting rod 23.

[0085] The clamping plate 2222 is fixedly mounted to the second end of the slide rod 21 away from the closing plate 1 by screw and nut fixings. The slide rod 21 is restricted in rotation by a limiting component. The limiting component includes a plurality of limiting rods 23 fixedly mounted in a circular shape on the side wall of the closing plate 1. The slide rods 21 are slidably sleeved on the limiting rods 23. The surface of the clamping plate 22 is bonded with an anti-slip layer made of rubber.

[0086] The clamping plate 22 is a circular plate, the outer arc surface of which is fixedly connected to the second end of the slide rod 21, and the inner arc surface of which is in contact with the outer side surface of the rubber sleeve 3. There are multiple auxiliary fixing assemblies, and the multiple auxiliary fixing assemblies are distributed in a ring around the central axis of the rubber sleeve 3.

[0087] When the rubber sleeve 3 and the sealing column 2 block the channel for the outflow of the grouting slurry, the multiple threaded rods 20 are rotated at this time. Since the sliding rod 21 can only move on the limit rod 23, when the threaded rod 20 rotates, the sliding rod 21 threadedly sleeved on the threaded rod 20 will move linearly with the clamping plate 22 without rotating with the threaded rod 20 until the surfaces of the multiple clamping plates 22 are tightly against the surface of the grouting joint. At this time, it can play an auxiliary role in fixing the plugger and the grouting joint, reducing the possibility of the rubber sleeve 3 and the sealing column 2 slipping out of the grouting joint, improving the stability of the sealing work, and the rubber has good elasticity and viscosity, which can also increase the friction between the contact surface of the clamping plate 22 and the grouting joint surface, and when the clamping plate 22 is severely worn, the screw and nut fixing parts make it convenient for the staff to replace the clamping plate 22 that is severely worn.
