Description

Technical Field

[0001] The utility model relates to the technical field of grouting sleeves, in particular to a steel bar grouting pre-embedded connecting sleeve. Background Art

[0002] The grouting sleeve is a combination of a specially processed sleeve, matching grouting material and steel bars. When connecting the steel bars, fast-hardening, non-shrinkage grouting material is injected, and the steel bars and sleeves are connected by relying on the bonding and biting effect between the materials.

[0003] After searching, the announcement number is CN220167171U, and the name is a utility model of a grouting sleeve, including a grouting sleeve body. Through research and analysis, it is found that although it can provide a reference for the staff to stop grouting in time, it can not only improve the quality of grouting, but also avoid mortar overflow and pollute the construction site and surrounding environment. However, there are still the following defects to a certain extent.

[0004] For example, the grouting sleeve cannot be disassembled. The grouting sleeve is an integral structure. It is inconvenient to take out the steel bars from the inside of the sleeve during the recycling process. The sleeve needs to be cut, so the sleeve cannot be used a second time. Moreover, when one side of the sleeve is damaged, the entire sleeve needs to be replaced, which undoubtedly increases the construction cost. In order to solve the above technical problems, we have designed a steel bar grouting pre-embedded connection sleeve. Utility Model Content

[0005] The purpose of the utility model is to provide a steel bar grouting pre-embedded connecting sleeve, which has the advantages of being able to disassemble the grouting sleeve, convenient for recycling and reuse, more flexible assembly, and reduced construction costs. It solves the problem that the sleeve cannot be disassembled for grouting, cannot be used again after recycling, and cannot be flexibly assembled, resulting in increased construction costs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel bar grouting embedded connecting sleeve, comprising a right side plate and a left side plate, connecting plates are welded on the front and rear sides of the right side plate, a plug-in opening is opened on the left side of the connecting plate, fixing plates are welded on the front and rear sides of the left side plate, a positioning plug-in plate is welded on the right side of the fixing plate, a positioning screw is passed through and fixedly connected to the bottom of the connecting plate, and anti-leakage baffles are plugged into the top and bottom between the right side plate and the left side plate.

[0007] Preferably, the right side plate includes a right sleeve, the top and bottom of the inner cavity of the right sleeve are provided with right positioning grooves, and sealing plug plates are welded on both the front and rear sides of the left side of the right sleeve.

[0008] Preferably, the left side plate includes a left sleeve, the top and bottom of the inner cavity of the left sleeve are both provided with left positioning grooves, and the front and rear sides of the right side of the left sleeve are both provided with sealing slots.

[0009] Preferably, a grouting pipe and a grouting pipe are respectively welded and connected to the top and bottom of the left side of the left sleeve, and the rear sides of the grouting pipe and the grouting pipe are both covered with protective sleeves.

[0010] Preferably, positioning plates are welded to both the left and right sides of the anti-leakage baffle, and the top of the positioning screw passes through the connecting plate and the positioning plug plate in sequence.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] Remove the nut on the top of the positioning screw surface from the connecting plate, remove the right plate and the left plate from the internal concrete surface. The disassembled right plate and left plate can be used again. When one side of the sleeve is damaged, only the damaged side needs to be removed and replaced with the intact side. The assembly and matching are more flexible, which greatly reduces the construction cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] See also Figure 1-Figure 4A steel bar grouting pre-embedded connection sleeve comprises a right side plate 1 and a left side plate 2. The front and rear sides of the right side plate 1 are welded with connection plates 7. The left side of the connection plate 7 is provided with a plug-in opening 12. By providing the plug-in opening 12, a positioning plug-in plate 8 can be inserted into the interior to achieve connection. The front and rear sides of the left side plate 2 are welded with fixing plates 3. The right side of the fixing plate 3 is welded with a positioning plug-in plate 8. A positioning screw 16 is fixedly connected to the bottom of the connection plate 7. The top and bottom between the right side plate 1 and the left side plate 2 are plugged with anti-leakage baffles 6. By providing the anti-leakage baffles 6, the slurry in the sleeve can be prevented from flowing out;

[0019] See also Figure 3 The right side plate 1 includes a right sleeve 15. The top and bottom of the inner cavity of the right sleeve 15 are provided with right positioning grooves 14. By providing the right positioning grooves 14 and the left positioning grooves 10, the positioning plates 17 on both sides of the leakage-proof baffle 6 can be inserted into the interior to position it. The front and rear sides of the left side of the right sleeve 15 are welded with sealing plug plates 13. By providing the sealing plug plates 13, they can be inserted into the sealing slots 9 on the left sleeve 11, thereby improving the connection sealing between the right sleeve 15 and the left sleeve 11 and preventing slurry leakage.

[0020] See also Figure 2 The left side plate 2 includes a left sleeve 11, the top and bottom of the inner cavity of the left sleeve 11 are provided with a left positioning groove 10, and the front and rear sides of the right side of the left sleeve 11 are provided with a sealing slot 9;

[0021] See also Figure 1 The top and bottom of the left side of the left sleeve 11 are respectively welded to the grouting pipe 5 and the grouting pipe 18, and the rear sides of the grouting pipe 5 and the grouting pipe 18 are both sleeved with a protective sleeve 4. By setting the protective sleeve 4, the openings of the grouting pipe 5 and the grouting pipe 18 can be protected;

[0022] See also Figure 4 Positioning plates 17 are welded on both sides of the leakage-proof baffle 6, and the top of the positioning screw 16 passes through the connecting plate 7 and the positioning plug plate 8 in sequence.

[0023] When in use, two steel bars are inserted into the sleeve from the upper and lower sides respectively, and then grouting is poured into the sleeve through the grouting pipe 18. When the slurry is full, it overflows from the grouting pipe 5, and then the grouting is stopped. After the slurry solidifies, the steel bar is fixed to complete the connection. When recycling, use a tool to remove the nut on the top of the surface of the positioning screw 16, and then remove the positioning screw 16 from the connecting plate 7, and then knock the right side plate 1 and the left side plate 2 off from the internal concrete surface. In this way, the splitting is completed, and there is no need for personnel to remove the sleeve by cutting. The split right side plate 1 and left side plate 2 can be used for a second time. When one side of the sleeve is damaged, there is no need to replace the entirety. Only the damaged side needs to be removed and replaced with a good one. The assembly and matching are more flexible, which greatly reduces the construction cost.

[0024] To sum up: the steel bar grouting embedded connecting sleeve, through the coordinated use of the right side plate 1, the left side plate 2, the connecting plate 7, the positioning plug plate 8, the sealing slot 9, the positioning screw 16 and the positioning plate 17, solves the problem that the sleeve cannot be disassembled due to grouting, cannot be reused after recycling, and cannot be flexibly assembled, resulting in increased construction costs.
