Description

Technical Field

[0001] This utility model relates to the field of concrete wall crack treatment technology, specifically a concrete shrinkage crack device. Background Technology

[0002] During construction, concrete walls frequently crack due to factors such as foundation settlement and thermal expansion and contraction. These cracks not only reduce the wall's strength but, in larger cases, significantly decrease its load-bearing capacity, especially in load-bearing structures like columns, walls, and bridge piers. Currently, a common repair method involves injecting filler into the cracks, most commonly using adhesive sealant. The specific application method involves injecting the sealant into the crack using a syringe or high-pressure pump. While this method is effective for cracks caused by thermal expansion and contraction, for load-bearing structures like piles and columns, the sealant can cause the cracks to widen further after filling due to the heavy load and the tendency for foundation settlement. This can lead to gaps forming between the hardened sealant and the existing wall cracks.

[0003] A concrete wall crack shrinkage sealing device disclosed in Chinese Utility Model Patent Application Publication No. CN221761481U, while employing a wrench to rotate a pull rod during the clamping and tightening process of the crack pulling component to maintain the crack in a vertical shrinkage state, thereby improving the shrinkage stability of the crack and preventing further enlargement, and while the resulting adhesive fully fills the crack with high stability, further enhancing the stability of the building structure, does not address the issues of drying and cooling the adhesive after wall repair and smoothing, or reducing secondary cracking of the wall after repeated fixing of the device. Therefore, this utility model is proposed to solve these problems. Utility Model Content

The lead screw thread passes through an adjusting frame, causing the adjusting frame to move horizontally. This achieves mutual adaptation between the adjusting frame and the equipment frame to fix the cracked column, effectively compressing and shrinking the cracked column and reducing the possibility of secondary cracking on the column surface. A limiting rod limits the movement of the adjusting frame, reducing displacement when fixing the column. Fixed supports are provided on the lower surfaces of the equipment frame and the adjusting frame. These fixed supports drive a telescopic rod, allowing for height adjustment.

A compression spring block drives the telescopic guardrail, aligning it with the inside of the telescopic rod to protect the column. The telescopic rod can be adjusted based on the required area of ​​the column / wall, making the protected area adjustable. Interlocking telescopic guardrails causes the internal compression spring block to deform, aligning the guardrail with the telescopic rod.

One end of the adjusting frame 5 has a threaded through hole, and the lead screw 3 passes through the adjusting frame 5. The adjusting frame 5 is slidably connected to the limit rod 4. The upper surfaces of both the equipment frame 1 and the adjusting frame 5 have threaded holes, and the bolt 16 is threaded through the threaded hole and the bracket 17. The lower surfaces of both the equipment frame 1 and the adjusting frame 5 are provided with adjusting rods 11 near the middle. The handrail 15 is located on the upper surface of the driven frame 14 near the limit rod 4. During use, a motor 2 is fixedly connected inside the equipment frame 1. Motor 2 drives lead screw 3, causing it to rotate. The lead screw 3, threaded through an adjusting frame 5, moves the adjusting frame 5, achieving a mutual adaptation between the adjusting frame 5 and the equipment frame 1 to fix the cracked column. This effectively compresses and contracts the cracked column, reducing the possibility of secondary cracking on its surface. A limiting rod 4 limits the movement of the adjusting frame 5, reducing displacement during column fixation. Fixed supports are located on the lower surfaces of the equipment frame 1 and the adjusting frame 5. These supports drive a telescopic rod 6, allowing for height adjustment.

The problem of displacement of the telescopic pole 6 during use is solved, greatly improving the stability of the equipment. By compressing the spring block 10, the telescopic guardrail 9 is driven to engage with the inside of the telescopic pole 6, thus protecting the column. The telescopic pole 6 can be adjusted according to the required area of ​​the column wall, making the protection area adjustable. The telescopic guardrail 9 is spliced ​​together, causing the internal compression spring block 10 to deform and engage with the telescopic pole 6.

[0027] like Figure 2 and Figure 3 As shown, in this embodiment, an adjusting rod 11 is inserted into the lower surface of the equipment frame 1, and a sleeve rod 12 is slidably connected to the outer surface of the adjusting rod 11. A fixing bolt 13 passes through the internal thread of the sleeve rod 12. A driven frame 14 is fixedly connected to the lower surface of the sleeve rod 12, and a handrail 15 is provided on the upper surface of the driven frame 14. A round hole is opened on one side of the adjusting rod 11, and the fixing bolt 13 passes through the sleeve rod 12 and the adjusting rod 11. Adjusting rods 11 are provided near the middle of the lower surface of the equipment frame 1 and the adjusting frame 5. The handrail 15 is located near the limit rod 4 on the upper surface of the driven frame 14. During use, the adjusting rod 11 slides inside the sleeve rod 12, causing the sleeve rod 12 to move. The height of the driven frame 14 is adjusted by fixing bolts 13 through which the sleeve rod 12 and the adjusting rod 11 are threaded, thus fixing the adjusting rod 11 and reducing the displacement of the sleeve rod 12 and the adjusting rod 11 during use. The adjusting rod 11 and the sleeve rod 12 provide fixed support for the driven frame 14, allowing the equipment frame 1 and the adjusting frame 5 to drive the driven frame 14 through the adjusting rod 11 and the sleeve rod 12, so that the driven frame 14 adjusts its position accordingly. This achieves a secondary stabilization effect on the column wall, greatly improving the stability of the equipment. The handrail 15 makes it easy for workers to pull down the driven frame 14 to adjust its height, greatly improving the stability of the equipment and increasing its utilization efficiency.

[0028] like Figure 2 and Figure 4As shown, in this embodiment, the equipment frame 1 has a bolt 16 inside, a bracket 17 on the outer surface of the bolt 16, a protective plate 18 inserted inside the bracket 17, a sliding block 19 slidably connected inside the protective plate 18, a smoothing block 20 slidably connected inside the protective plate 18, a scraper 21 fixedly connected to one side of the smoothing block 20, and a fan box 22 inserted inside the protective plate 18. Threaded holes are provided on the upper surfaces of both the equipment frame 1 and the adjusting frame 5. The bolt 16 is threaded through the threaded hole and the bracket 17. The fan box 22 is hollow inside, and a filter screen is provided on one side of the fan box 22. During use, the bolt 16 is threaded through the upper surfaces of the equipment frame 1 and the adjusting frame 5, allowing the bolt 16 to thread through the bracket 17, thus fixing the bracket 17 to the lower surfaces of the equipment frame 1 and the adjusting frame 5. This reduces the problem of bracket 17 displacement and prevents the bracket 17 from falling off. A protective plate 18 is inserted into the inside of the bracket 17, making the protective plate 18 detachable and facilitating its disassembly and storage. A sliding block 19 and a smoothing block 20 are slidably connected inside the protective plate 18, allowing them to slide up and down. A docking hole on one side of the sliding block 19 allows it to connect to a caulking gun, facilitating the filling of cracked walls. This achieves wall shrinkage repair, reducing the risk of secondary cracking. The smoothing block 20 drives the scraper 21, smoothing the cracks after caulking, improving equipment efficiency. A filter screen on one side of the fan box 22 allows air to pass through, driving the internal fan to dry the caulking adhesive on the wall surface, achieving a rapid repair effect. The protective plate 18 supports the fan box 22, reducing the risk of it falling or shifting, and greatly improving the stability of the equipment.

[0029] The working principle of this practical application is as follows:

[0030] During use, a motor 2 is fixedly connected inside the equipment frame 1. The motor 2 drives a lead screw 3, causing the lead screw 3 to rotate. An adjusting frame 5 is threaded through the lead screw 3, causing the lead screw 3 to move the adjusting frame 5 horizontally. This achieves mutual adaptation between the adjusting frame 5 and the equipment frame 1 to fix the cracked column, effectively compressing and shrinking the cracked column and reducing the possibility of secondary cracking on the column surface. A limiting rod 4 limits the movement of the adjusting frame 5, reducing displacement when fixing the column. A fixed bracket is provided on the lower surface of the equipment frame 1 and the adjusting frame 5. This fixed bracket drives a telescopic rod 6, allowing for height adjustment. A spring 7 drives a protrusion 8, causing the protrusion to... The internal structure of the fixed bracket limits the telescopic rod 6, reducing displacement during use and significantly improving equipment stability. The compression spring block 10 drives the telescopic guardrail 9, aligning it with the inside of the telescopic rod 6 to protect the column. The telescopic rod 6 can be adjusted to accommodate the required area of ​​the column / wall, making its protective area adjustable. The interlocking of the telescopic guardrails 9 causes the internal compression spring block 10 to deform, aligning the telescopic guardrail 9 with the telescopic rod 6. A threaded end on one end of the telescopic guardrail 9 secures it within the telescopic rod 6, achieving protection of the column / wall and reducing secondary cracking of the concrete wall, thus greatly improving the equipment's overall safety. This system improves equipment efficiency and facilitates subsequent angle adjustments. The adjusting rod 11 slides within the sleeve rod 12, allowing the sleeve rod 12 to adjust the height of the driven frame 14. A fixing bolt 13, threaded through the sleeve rod 12 and adjusting rod 11, secures the adjusting rod 11, reducing displacement during use. The adjusting rod 11 and sleeve rod 12 provide fixed support for the driven frame 14, allowing the equipment frame 1 and adjusting frame 5 to adjust their positions, thus achieving secondary stabilization of the column wall and significantly improving equipment stability. A handrail 15 facilitates easy access for workers to pull down the driven frame 14. Adjusting the height greatly improves the stability of the equipment, increases its efficiency, and facilitates subsequent repair of cracked concrete walls. Bolts 16 threaded through the upper surfaces of the equipment frame 1 and adjusting frame 5, and bolts 16 threaded through the bracket 17, fixing the bracket 17 to the lower surfaces of the equipment frame 1 and adjusting frame 5. This reduces the risk of the bracket 17 shifting or falling. A protective plate 18 is inserted inside the bracket 17, making it detachable and easy to disassemble and store. A sliding block 19 and a smoothing block 20 are slidably connected inside the protective plate 18, allowing them to slide up and down. A mating hole is provided on one side of the sliding block 19.This design allows for connection to a caulking gun, facilitating the filling of cracked walls. It achieves repair after wall shrinkage, reducing the risk of secondary cracking. The smoothing block 20 drives the scraper 21, which smooths the cracks after caulking, improving equipment efficiency. A filter on one side of the fan box 22 allows air to pass through, driving the internal fan to dry the caulking adhesive on the wall surface, resulting in rapid repair. The protective plate 18 supports the fan box 22, reducing the risk of it falling or shifting, and significantly improving equipment stability.
