Description

Technical Field

[0001] This utility model relates to the field of crack reinforcement technology, specifically a structure for reinforcing and strengthening cracks in building structures. Background Technology

[0002] Concrete structures are a common building structure in modern construction. Concrete walls can develop cracks due to external influences, which can cause leakage and affect normal use. Therefore, it is necessary to fill the cracks. The current method of filling concrete cracks is to directly fill the cracks with filler. However, directly using filler cannot stop the cracks from expanding. The cracks will continue to expand after being filled, resulting in poor filling effect.

[0003] According to a concrete crack reinforcement structure with application number 202220582697.8, the structure consists of a concrete wall, a crack, and a reinforcement mechanism. In use, two limiting plates on the reinforcement plate are inserted into two limiting slots, and the reinforcement plate is fixed to the concrete wall using expansion bolts. The reinforcement plate reinforces the cracks in the concrete wall, thus inhibiting further expansion of the cracks. Rotating the sealing cap disengages it from the filling tube, releasing the seal. Filler is then injected into the crack through the filling tube and filling hole, thus filling and reinforcing the crack. After filling, the sealing cap is screwed back on, completing the reinforcement of the concrete wall crack and effectively improving the reinforcement effect.

[0004] However, the above-mentioned concrete crack reinforcement structure still has certain shortcomings. The reinforcement plate of this structure is positioned by limiting groove and limiting plate, and it can be fixed by expansion bolts. However, the fixing position depends on the installation of the expansion bolts. If the installation position of the expansion bolts is offset, although the reinforcement plate can be installed on the outside of the concrete wall crack, the tensile strength is poor after installation and it cannot apply a certain tensile force to the building crack, thus having certain shortcomings. Therefore, we propose a building structure crack reinforcement structure. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Please see Figures 1 to 8 This utility model provides a technical solution: a building structure crack reinforcement structure, including a building wall 1, fixed side plates 3 and a reinforcement middle plate 4. The surface of the building wall 1 is provided with a positioning groove 2 on the outside of the crack. The fixed side plates 3 and the reinforcement middle plate 4 are disposed inside the positioning groove 2. A tensioning mechanism is provided on the outside of the fixed side plates 3 and the reinforcement middle plate 4. The reinforcement middle plate 4 is disposed inside the positioning groove 2 on the outside of the crack. The two fixed side plates 3 are fixedly installed on both sides of the crack inside the positioning groove 2. A certain tension can be applied to the two fixed side plates 3 through the tensioning mechanism, thereby improving the reinforcement performance of the crack.

[0030] The tensioning mechanism includes a concave frame 10, a bidirectional threaded rod 11, two sleeve blocks 12, several tie rods 13, and a connecting plate 14. The concave frame 10 is fixedly installed in the middle of the outer side of the reinforced middle plate 4. The bidirectional threaded rod 11 is rotatably installed inside the concave frame 10. The two sleeve blocks 12 are threadedly installed on the outer side of the bidirectional threaded rod 11. Several tie rods 13 are rotatably installed on both sides of the two sleeve blocks 12. Several connecting plates 14 are fixedly installed on the outer side of the fixed side plate 3. Several tie rods 13 are rotatably connected to one side of the connecting plate 14. By rotating the bidirectional threaded rod 11, the two sleeve blocks 12 can be moved towards the middle of the bidirectional threaded rod 11 through the threads. At the same time as the sleeve blocks 12 move, a certain tension can be applied to the connecting plate 14 through the tie rods 13, so that the tension acts on both sides of the crack on the fixed side plate 3, preventing the crack from expanding further.

[0031] Both the building wall 1 and the fixed side plate 3 are equipped with fixing mechanisms for installation; the fixing mechanisms facilitate the installation of the fixed side plate 3 and the reinforced middle plate 4 inside the building wall 1.

[0032] The fixing mechanism includes several square through holes 5, a threaded cylinder 6, countersunk bolts 7, and nuts 9. The square through holes 5 are respectively opened inside the four corners of the positioning groove 2. The threaded cylinder 6 is inserted into the square through holes 5. Two connecting holes 8 are opened inside the two fixing side plates 3. The countersunk bolts 7 are engaged with the connecting holes 8 and the threaded cylinder 6. The nuts 9 are threaded on the outside of the countersunk bolts 7. The fixing side plates 3 and the reinforcing middle plate 4 are installed by inserting the threaded cylinder 6 into the square through holes 5, placing the fixing side plates 3 and the reinforcing middle plate 4 inside the positioning groove 2, passing the countersunk bolts 7 through the connecting holes 8 and the threaded cylinder 6, and then installing the nuts 9 on the outside of the countersunk bolts 7 from inside the building. When the nuts 9 are installed on the outside of the countersunk bolts 7, the threaded cylinder 6 and the countersunk bolts 7 can be limited from inside the building by adding a washer on the outside of the countersunk bolts 7, thereby preventing the threaded cylinder 6 from slipping out of the square through holes 5.

[0033] An adjustment mechanism is provided on one side of the reinforced middle plate 4; the adjustment mechanism can be used to adjust the pulling force of the tie rod 13.

[0034] The adjustment mechanism includes a rotating shaft 15, a worm gear 16, and a worm wheel 17. The rotating shaft 15 is rotatably mounted on one side of the reinforced middle plate 4 and is rotatably connected to the concave frame 10. The worm gear 16 is fixedly mounted on the outside of the rotating shaft 15, and the worm wheel 17 is fixedly mounted on the outside of the double-threaded rod 11. The worm gear 16 and the worm wheel 17 mesh. One end of the rotating shaft 15 is fixedly mounted with an internal hex head 18. The internal hex head 18 needs to be used with an external hex wrench. By inserting the hex wrench into the internal hex head 18 and rotating the rotating shaft 15, the worm gear 16 and the worm wheel 17 will mesh, thereby driving the double-threaded rod 11 to rotate. After the double-threaded rod 11 rotates, it can drive the two sleeve blocks 12 through its external threads, thereby adjusting its tension.

[0035] The middle part of the reinforced plate 4 is equipped with an injection pipe 19, which is matched with the cracks inside the building wall 1; grout can be injected into the cracks through the injection pipe 19 for repair.

[0036] One end of the injection pipe 19 passes through the interior of the concave frame 10, and a threaded cap 20 is threaded on the outside of the injection pipe 19; the threaded cap 20 can seal the injection pipe 19 after the grouting is completed.

[0037] The threaded cylinder 6 has a hole inside that mates with the countersunk bolt 7. The fixed side plate 3 has a countersunk groove inside that mates with the countersunk bolt 7 on the side of the connecting hole 8. The countersunk bolt 7 can pass through the hole inside the threaded cylinder 6, and the end of the countersunk bolt 7 can be recessed into the groove on the side of the connecting hole 8.

[0038] Both sides of the sleeve block 12 and one side of the connecting plate 14 are provided with hinges that cooperate with the pull rod 13; by providing hinges on one side of the sleeve block 12 and the connecting plate 14, the pull rod 13 can be rotatably connected to the sleeve block 12 and the connecting plate 14 respectively.

[0039] In summary, the structural crack reinforcement structure is used as follows: First, a positioning groove 2 is opened on the outer side of the crack on the surface of the building wall 1 to accommodate the fixed side plate 3 and the reinforced middle plate 4. Then, a square through hole 5 is opened, and a threaded cylinder 6 is inserted into the square through hole 5. After installing the fixed side plate 3 and the reinforced middle plate 4 into the positioning groove 2, the countersunk bolt 7 is inserted into the connecting hole 8 so that it passes through the interior of the threaded cylinder 6. Then, a washer is placed on the outer side of the countersunk bolt 7 on the back of the building wall 1. Then, the nut 9 is screwed onto the outer side of one end of the countersunk bolt 7 to install and fix the fixed side plate 3 and the reinforced middle plate 4. Finally, a hex wrench is used to fix the structure. After inserting your hand into the hexagonal head 18, rotating the shaft 15 will engage the worm gear 16 with the worm wheel 17, thereby driving the double-threaded rod 11 to rotate. After the double-threaded rod 11 rotates, it will drive the two sleeve blocks 12 to move towards the middle of the double-threaded rod 11 through the threads. At the same time as the sleeve blocks 12 move, a certain tension can be applied to the connecting plate 14 through the pull rod 13, so that the tension is applied to both sides of the crack on the fixed side plate 3. Finally, unscrew the threaded cap 20 and inject grout into the crack inside the building wall 1 through the injection pipe 19 for repair. After the grouting is completed, tighten the threaded cap 20 on the outside of the injection pipe 19 to complete the crack reinforcement.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
