Description

Technical Field

[0001] The utility model belongs to the technical field of concrete crack repair, and in particular relates to a basement concrete outer wall crack repair device. Background Art

[0002] At present, cities are developing rapidly. Due to the shortage of above-ground space, the development and use of underground space has attracted more and more attention, which has led to the basement part of the building being increasingly valued. In the construction of the basement, cracking and leakage of basement concrete is one of the difficult problems of the project. The risk of cracking of the side wall is relatively prominent compared to the cracking of the bottom plate. How to take targeted treatment measures for cracking of the side wall is the key to ensuring the waterproof quality of the basement.

[0003] The document with the authorization announcement number CN217232867U discloses a basement side wall concrete crack control structure, including a first reserved grouting hole connected to the concrete crack, and the control structure includes a hose, a fixed block and a high-pressure pump. The fixed block is used to connect to the first reserved grouting hole, one end of the hose is connected to the high-pressure pump, and the other end of the hose is used to extend into the first reserved grouting hole. This solution fills the crack by grouting into the grouting hole connected to the crack to bond it and prevent the crack from expanding. However, the grouting hole needs to be completed when pouring concrete, which not only increases the difficulty of the pouring process, but the existence of the grouting hole will also affect the structural strength of the concrete itself.

[0004] The document with the authorization announcement number 222848926U discloses a basement crack concrete pouring device, including a mounting seat, a storage barrel, a delivery pump, a lifting mechanism, a pouring piece, a smoothing mechanism and a receiving mechanism; the storage barrel, the delivery pump and the lifting mechanism are all mounted on the mounting seat, the feed end of the delivery pump is connected to the storage barrel, and the discharge end of the delivery pump is connected to the pouring piece through a delivery pipe; the pouring piece is arranged at the top of the lifting mechanism, the receiving mechanism is arranged between the pouring piece and the lifting mechanism, and the smoothing mechanism is arranged above the pouring piece. The device fills the gap by finding the gap and grouting, but this grouting method needs to fill the gap as deep as possible, so the pouring piece needs to stay in the gap for a long time, and the work efficiency is low.

[0033] Example 1

[0034] As attached Figure 1~2 As shown, this embodiment provides a basement concrete exterior wall crack repair device, which includes a grouting device 1 and a control device 2 for conveying the grouting device 1.

[0035] In this embodiment, the grouting device 1 includes a slurry storage barrel 11 and a piston core rod 12 disposed in the slurry storage barrel 11. The grouting device 1 can directly refer to the syringe structure in the prior art, except that: an internal thread 111 is provided on the opening of the injection end of the slurry storage barrel 11, and an external thread discharge barrel 112 is screwed onto the internal thread 111. The purpose of this arrangement is to ensure the sealing of the structure, and the second purpose is to make the external thread discharge barrel 112 removable and replaceable to be suitable for construction scenes with different gap sizes.

[0036] In this embodiment, the control device 2 includes a base plate 21, a lifting structure 22 arranged on the base plate 21, a mounting platform 23 arranged on the lifting structure 22, a fixer 24 arranged on the mounting platform 23 and used to fix the slurry storage barrel 11, and a driver 25 arranged on the mounting platform 23 and driving the piston core rod 12 to compress the slurry in the slurry storage barrel 11.

[0037] The bottom plate 21 is provided with a roller 211, and the bottom plate 21 is provided with a handle 212 at one end away from the grouting device 1. This arrangement facilitates the control of the entire device to move and improves construction efficiency.

[0038] The lifting structure 22 is a structure that can drive the installation platform 23 to rise and fall in the vertical direction. The existing technology can be directly adopted, so it will not be described in detail in this embodiment.

[0039] The fixture 24 includes a support rod 241 and a support ring 242 disposed on the support rod 241. In this embodiment, there may be multiple fixtures 24, which respectively support various positions of the slurry storage barrel 11 to prevent the slurry storage barrel 11 from moving.

[0040] The driver 25 acts on the piston core rod 12 to push the piston core rod 12 to move in the slurry storage barrel 11 toward the injection end of the slurry storage barrel 11, thereby pushing the filling slurry to be discharged into the gap.

[0041] The working principle of the crack repair device provided in this embodiment is: the operating handle 212 pushes the bottom plate 21 to drive the entire device to move to the lower end of the gap to be repaired, the grouting device 1 is installed on the fixture 24, and then the lifting structure 22 is started to drive the installation platform 23 to lift until it reaches the predetermined position; the position of the bottom plate 21 is further adjusted until the injection end of the slurry storage barrel 11 is inserted into the gap; finally, the driver 25 is started to push the piston core rod 12 to gradually push the slurry inside the barrel into the gap.

[0042] It should be noted that the front end of the mounting platform 23 cannot exceed the injection end of the slurry storage barrel 11, and the capacity of the slurry in the grouting device 1 is determined according to the usage amount calculated in advance according to the gap.

[0043] Compared with the prior art, the crack repairing device provided in this embodiment has the following advantages: first, the injection volume of the slurry can be accurately controlled to ensure the filling effect; second, the filling speed of the slurry can be increased to improve work efficiency.

[0044] Example 2

[0045] This embodiment optimizes and transforms the structure of the fixer 24 on the basis of the embodiment 1. Figure 3 and attached Figure 4 As shown, the details are as follows:

[0046] The fixer 24 also includes a fixed cylinder 243 which is sleeved on the outside of the slurry storage cylinder 11 and rotatably connected to the support ring 242, a drilling ring 244 which is arranged on the same side of the fixed cylinder 243 and the injection end of the slurry storage cylinder 11 and has a gradually decreasing inner diameter, a fixed gear 245 installed on the outside of the fixed cylinder 243, a support plate 246 arranged on the mounting platform 23, a rotating motor 247 arranged on the support plate 246, and a driving gear 248 arranged on the output end of the rotating motor 247 and meshing with the fixed gear 245.

[0047] Furthermore, the fixture 24 further comprises a ball 1 249 arranged on the opening of the drilling ring 244 ; and a ball 2410 arranged on the inner wall of the fixing cylinder 243 and rotatably connected to the slurry storage cylinder 11 .

[0048] It is understandable that the structure of the support rod 241 and the support ring 242 in this embodiment is used to assist in supporting the fixed cylinder 243. And the opening of the drilling ring 244 is flush with the opening of the discharge cylinder 112 or slightly ahead of the opening of the discharge cylinder 112 in the horizontal direction.

[0049] The working principle of the fixer 24 in this embodiment includes: before grouting, starting the rotating motor 247 to drive the driving gear 248 to drive the fixed gear 245 to rotate, thereby driving the fixed cylinder 243 to rotate, and the drilling ring 244 at the front end of the fixed cylinder 243 can act on the wall at the gap, and through rotation, a pit connected to the gap is punched in the wall, thereby increasing the size of the aperture on the surface of the gap and improving the success rate and efficiency of grouting.

[0050] The advantages of the fixer in this embodiment are: first, it can improve the success rate and efficiency of grouting when used before grouting; second, it can drive the slurry storage barrel in the fixed barrel to rotate together, mix the slurry and avoid stratification.

[0051] Example 3

[0052] This embodiment optimizes the lifting structure 22 based on the embodiment 2, as shown in the attached Figure 5 As shown, the details are as follows:

[0053] The lifting structure 22 includes a lifting cylinder 221, a base 222 arranged on the output end of the lifting cylinder 221, a slide groove 223 arranged on the base 222, a slider 224 arranged at the lower end of the mounting platform 23 and slidably connected to the slide groove 223, and a control rod 225 arranged at the end of the mounting platform 23 away from the slider 224.

[0054] As a further preference of this embodiment, the lifting structure 22 also includes a fixing plate 226 arranged on the base plate 21, a transverse opening 227 arranged on the fixing plate 226, and an extension rod 228 arranged at the lower end of the control rod 225 and slidably connected to the transverse opening 227.

[0055] As a further preferred embodiment of the present invention, the lifting structure 22 further includes a tension spring 229 with two ends respectively connected to the fixing plate 226 and the control rod 225 .

[0056] The main purpose of the lifting structure 22 provided in this embodiment is to help enhance the drilling effect of the fixture 24; when the fixture 24 rotates, the control rod 225 is pushed by the control extension rod 228 to drive the entire installation platform 23 to move along the slide groove 223 toward the injection end, so that a suitable pressure is generated between the drilling ring 244 and the wall surface, helping to quickly punch a suitable pit. After the rotation of the fixture 24 is completed or the slurry injection is completed, the control of the extension rod 228 is removed, and under the action of the tension spring 229, the installation platform 23 will drive the structure on the platform to return to its original position.

[0057] Example 4

[0058] This embodiment can be structurally optimized based on any one of the solutions in Embodiments 1 to 3, as shown in the attached Figure 6 As shown, the details are as follows:

[0059] The control device 2 also includes a mounting groove 231 arranged on the mounting platform 23, a mounting rod 232 arranged in the mounting groove 231 and located on the side of the piston core rod 12 away from the injection end of the slurry storage barrel 11, a baffle 233 rotatably mounted on the mounting rod 232, and a torsion spring 234 for connecting the mounting rod 232 and the baffle 233 and keeping the baffle 233 perpendicular to the mounting groove 231.

[0060] It is worth noting that the baffle 233 is located at the rear end of the farthest end of the piston core rod 12 when the groove 231 is installed vertically, so as to prevent the piston core rod 12 from being pushed and causing the slurry to leak out; at the same time, the baffle 233 can be in contact with the surface of the output end of the driver 25 when the groove 231 is installed vertically, so as to play the effect of marking and blocking the driver 25. When the driver 25 needs to push the piston core rod 12, it needs to first contact the baffle 233 and push it into the installation groove 231 to avoid leakage of slurry due to improper operation.

[0061] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
