Description

Technical Field

[0001] This utility model relates to the field of crack sealing technology, specifically to a device for sealing shrinkage cracks in concrete walls. 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, threatening the building's safety. Traditional crack sealing methods include surface coating and pressure grouting, but these methods have drawbacks such as unsatisfactory sealing effects, complex construction, and high costs. Therefore, concrete wall crack shrinkage sealing devices are needed.

[0003] For example, Chinese Patent CN221761481 U discloses a crack shrinkage sealing device for concrete walls, including a crack pulling and shrinkage mechanism. The crack pulling and shrinkage mechanism includes several crack pulling components spaced vertically. Each crack pulling component includes locking plates spaced horizontally, with side plates connected to both ends of the locking plates. The side plates are connected to the locking plates via an adjusting structure. The crack pulling components are connected to each other via several adjusting pulling parts, which tighten the components together. Each adjusting pulling part includes a central pull column, with threaded pull rods at its top and bottom. A pull ring is rotatably connected to the top of the pull rod and hangs on the side plates. This device effectively pulls and shrinks cracks in building walls, ensuring crack reinforcement and preventing them from widening.

[0004] Although the above example can compress and shrink cracks on the surface of concrete walls in the Z and X directions, the cracking direction of the concrete wall is random when it cracks. When the cracking direction corresponds to the Y shrinkage direction, the device does not have the function of shrinking in the Y direction, resulting in poor shrinkage effect and certain inconveniences in use. Utility Model Content

[0005] This invention provides a device for sealing shrinkage cracks in concrete walls to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A concrete wall crack shrinkage sealing device includes an X-axis shrinkage mechanism, with a Y-axis shrinkage mechanism fixedly connected to both ends of the X-axis shrinkage mechanism, and a Z-axis shrinkage mechanism provided on the surface of the X-axis shrinkage mechanism. The X-axis shrinkage mechanism includes an X-axis shrinkage component, with a first assembly fixedly connected to both ends of the X-axis shrinkage component, and a first rotating component fixedly connected to one side of the X-axis shrinkage component. A first fastener is rotatably connected to the surface of the first rotating component, and a hanging ring is fixedly connected to the surface of the first assembly.

[0008] A further improvement of the present invention is that the Y-axis retraction mechanism includes a Y-axis retraction component, and a second rotating component is fixedly connected to the surface of the Y-axis retraction component.

[0009] A further improvement of this utility model is that: the surface of the second rotating member is fixedly connected with a second fastener, and both ends of the Y-axis retractable member are fixedly connected with a second assembly bolted to the first assembly.

[0010] A further improvement of the present invention is that the Z-axis retraction mechanism includes a third fastener, and hooks are fixedly connected to both ends of the third fastener, with the surface of the hooks overlapping the inner wall of the hanging ring.

[0011] A further improvement of the present invention is that the X-axis shrinking component includes a plug-in part and a sleeve part, and one end of the plug-in part is plugged into the interior of the sleeve part.

[0012] A further improvement of this utility model is that the two first rotating parts are fixedly connected to the sides of the insertion part and the sleeve part respectively, and the structure of the X-axis shrinking part is the same as that of the Y-axis shrinking part.

[0013] A further improvement of this utility model is that the first fastener includes a threaded rod, one end of which is rotatably connected to the surface of the first rotating component.

[0014] A further improvement of this utility model is that: the surface of the threaded rod is threaded with a threaded sleeve, the surface of the threaded sleeve is provided with a hexagonal prism, and the structure of the first fastener is the same as the structure of the second and third fasteners.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] This utility model provides a concrete wall crack shrinkage sealing device. By setting the Y-axis shrinkage mechanism, when shrinking and filling the cracks in the concrete wall, the Y-axis shrinkage member can be contracted by rotating the second fastener, applying pressure in the Y-axis direction to the building wall. At the same time, in conjunction with the X-axis shrinkage mechanism and the Z-axis shrinkage mechanism, the device can have a three-dimensional shrinkage force, making it adaptable to wall cracks with different cracking directions, thus having greater applicability.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] Example 1

[0025] like Figure 1-5 As shown, this utility model provides a concrete wall crack shrinkage sealing device, including an X-axis shrinkage mechanism, a Y-axis shrinkage mechanism fixedly connected to both ends of the X-axis shrinkage mechanism, a Z-axis shrinkage mechanism provided on the surface of the X-axis shrinkage mechanism, the X-axis shrinkage mechanism including an X-axis shrinkage component 11, a first assembly component 12 fixedly connected to both ends of the X-axis shrinkage component 11, a first rotating component 13 fixedly connected to one side of the X-axis shrinkage component 11, a first fastener 14 rotatably connected to the surface of the first rotating component 13, and a hanging ring 15 fixedly connected to the surface of the first assembly component 12.

[0026] In this embodiment, when shrinking cracks on the surface of a concrete wall, after grouting the cracks, the first assembly 12 and the second assembly 24 of multiple X-axis shrinkage mechanisms and Y-axis shrinkage mechanisms are connected by bolts so that they are evenly wrapped around the surface of the concrete wall. Then, the hexagonal post 143 inside the first fastener 14 is rotated to rotate the threaded sleeve 142, causing the threaded rod 141 to shrink into the threaded sleeve 142, thereby driving the insertion part 111 to insert into the sleeve part 112 and applying a shrinkage force in the X-axis direction to the concrete wall.

[0027] Example 2

[0028] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the Y-axis retraction mechanism includes a Y-axis retraction component 21, a second rotating component 22 is fixedly connected to the surface of the Y-axis retraction component 21, a second fastener 23 is fixedly connected to the surface of the second rotating component 22, and a second assembly 24, which is bolted to the first assembly 12, is fixedly connected to both ends of the Y-axis retraction component 21.

[0029] In this embodiment, by rotating the hexagonal post 143 inside the first fastener 14, the threaded sleeve 142 is rotated, causing the threaded rod 141 to retract into the threaded sleeve 142, thereby driving the insertion part 111 to insert into the sleeve part 112 and applying a contraction force in the X-axis direction to the concrete wall. Then, by rotating the hexagonal post inside the second fastener 23, the Y-axis contraction part 21 can apply a Y-axis contraction force to the concrete wall.

[0030] Example 3

[0031] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the Z-axis retraction mechanism includes a third fastener 31, with hooks 32 fixedly connected to both ends of the third fastener 31. The surface of the hooks 32 overlaps with the inner wall of the hanging ring 15. The X-axis retraction component 11 includes an insertion part 111 and a sleeve part 112. One end of the insertion part 111 is inserted into the inside of the sleeve part 112. Two first rotating parts 13 are fixedly connected to the sides of the insertion part 111 and the sleeve part 112, respectively. The structure of the X-axis retraction component 11 is the same as that of the Y-axis retraction component 21. The first fastener 14 includes a threaded rod 141, with one end of the threaded rod 141 rotatably connected to the surface of the first rotating part 13. A threaded sleeve 142 is threadedly connected to the surface of the threaded rod 141. A hexagonal prism 143 is provided on the surface of the threaded sleeve 142. The structure of the first fastener 14 is the same as that of the second fastener 23 and the third fastener 31.

[0032] In this embodiment, by hanging the hook 32 onto the surface of the hanging ring 15 and rotating the hexagonal post inside the third fastener 31, the third fastener 31 can be contracted to apply a Z-axis contraction force to the concrete wall. The three-way contraction allows the injected filler to contact the inner wall of the crack more tightly, resulting in a better filling effect.

[0033] The working principle of this concrete wall crack shrinkage sealing device will be explained in detail below.

[0034] like Figure 1-5 As shown, when shrinking cracks on the surface of a concrete wall, after grouting the cracks, the first assembly 12 and the second assembly 24 of multiple X-axis shrinkage mechanisms and Y-axis shrinkage mechanisms are connected by bolts, so that they are evenly wrapped around the surface of the concrete wall. Then, the hexagonal post 143 in the first fastener 14 is rotated, causing the threaded sleeve 142 to rotate, causing the threaded rod 141 to shrink into the threaded sleeve 142, thereby driving the insertion part 111 to insert into the sleeve part 112, applying a shrinkage force in the X-axis direction to the concrete wall. Then, the hexagonal post in the second fastener 23 is rotated, and similarly, the Y-axis shrinkage part 21 can apply a Y-axis shrinkage force to the concrete wall. After the hook 32 is hung on the surface of the hanging ring 15, the hexagonal post in the third fastener 31 is rotated, so that the third fastener 31 shrinks and applies a Z-axis shrinkage force to the concrete wall. The three-way shrinkage method can make the injected filler contact the inner wall of the crack more tightly, and the filling effect is better.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
