Description

Technical Field

[0001] The utility model relates to the field of waterproof construction inspection, and particularly relates to a crack detection tool for waterproof construction. Background Art

[0002] The bathroom is one of the areas with the most water vapor and humidity in the family. Therefore, the waterproof construction of the bathroom is very important. In the waterproof construction of the bathroom, crack detection is a crucial step. Construction workers need to comprehensively and accurately evaluate the integrity of the waterproof layer in order to timely discover and solve any potential problems to ensure the integrity and long-term effect of the waterproof layer.

[0003] The prior art has the following deficiencies: In traditional bathroom waterproof construction, crack detection mainly relies on visual inspection, tactile inspection, and water release tests, etc. For some extremely tiny cracks, they may be covered by dust and soil at the construction site. Therefore, visual inspection and tactile inspection are difficult to detect. And due to the surface tension of water, during the water release test, water will not penetrate through these extremely tiny cracks, which may create an illusion of no cracks. Although these tiny cracks may not be obvious initially, over time and with the increase of usage pressure, they may gradually expand, eventually leading to water leakage and structural damage.

[0004] Therefore, it is necessary to invent a crack detection tool for waterproof construction. Content of the Utility Model

[0005] In order to achieve the above object, the utility model provides the following technical solution: A crack detection tool for waterproof construction, including an outer shell. One side of the outer wall of the outer shell is provided with an opening. A transparent panel is fixedly installed in the opening on the outer wall of the outer shell. A slide rail is fixedly installed on the surface of the outer shell on one side of the transparent panel. A sliding scale is slidably installed on the slide rail. A pressing plate is slidably installed on the inner wall of the outer shell. A water injection port is arranged on the top surface of the pressing plate. Four corners of the top surface of the outer shell are fixedly installed with flat plates. A hydraulic push rod is fixedly installed on the top surface of the flat plate. The lower end of the hydraulic push rod penetrates through the flat plate and is fixedly connected with the top surface of the pressing plate.

[0006] Preferably, an inner shell plate is fixedly installed on the inner wall of the outer shell. The inner shell plate surrounds the inner wall of the outer shell, and a gap is formed between the inner shell plate and the outer shell.

[0007] Preferably, a vacuum air pump is fixedly installed on the outer wall of the outer shell. The vacuum air pump penetrates through the outer shell and extends into the gap between the outer shell and the inner shell plate.

[0020] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0021] Example 1

[0022] As Figure 1 - Figure 3 shown, a waterproof construction crack detection tool in the first aspect embodiment of the present utility model includes an outer shell 11. One side of the outer wall of the outer shell 11 is provided with an opening. A transparent panel 12 is fixedly installed in the opening of the outer wall of the outer shell 11. A slide rail 21 is fixedly installed on the surface of the outer shell 11 on one side of the transparent panel 12. A sliding scale 22 is slidably installed on the slide rail 21. A pressing plate 17 is slidably installed on the inner wall of the outer shell 11. A water injection port 18 is arranged on the top surface of the pressing plate 17. Four corners of the top surface of the outer shell 11 are fixedly installed with flat plates 14. A hydraulic push rod 16 is fixedly installed on the top surface of the flat plates 14. The lower end of the hydraulic push rod 16 penetrates through the flat plates 14 and is fixedly connected to the top surface of the pressing plate 17.

[0023] In the above embodiment, it should be noted that the outer shell 11 is closely attached to the ground to be detected. Then, a certain amount of water is injected into the outer shell 11 through the water injection port 18. The sliding scale 22 is flush with the water surface. Finally, the hydraulic push rod 16 is started to push the pressing plate 17 to squeeze the water in the outer shell 11 downward, increasing the water pressure to achieve the effect of making the water enter the tiny cracks that usually cannot penetrate, avoiding misjudgment of tiny cracks by the detection device due to the surface tension of the water, and eliminating the possibility of the gradual expansion of tiny cracks in the later stage, ultimately leading to water leakage and structural damage. After the water pressure is increased for a period of time, the hydraulic push rod 16 is controlled to drive the pressing plate 17 to reset. Then, the water surface is observed through the transparent panel 12. If the water surface is significantly lower than the sliding scale 22, it indicates that there are cracks in the detection area. If the water surface is slightly lower than the sliding scale 22, it belongs to normal loss, indicating that there are no cracks in the detection area.

[0025] As Figure 1 - Figure 4 shown, a waterproof construction crack detection tool includes all the contents of Example 1. In addition, an inner shell plate 13 is fixedly installed on the inner wall of the outer shell 11. The inner shell plate 13 is arranged around the inner wall of the outer shell 11. A gap is formed between the inner shell plate 13 and the outer shell 11. A vacuum air pump 20 is fixedly installed on the outer wall of the outer shell 11. The vacuum air pump 20 penetrates through the outer shell 11 and extends into the gap between the inner shell plate 13 and the inner shell plate 13. The bottom surface of the outer shell 11 is flush with the bottom surface of the inner shell plate 13. A sealing rubber strip 23 is fixedly bonded to the bottom surface of the outer shell 11. A sealing rubber strip 23 is also fixedly bonded to the bottom surface of the inner shell plate 13.

[0026] In the above embodiments, it should be noted that the sealing strip 23 is made of rubber material. The sealing strip 23 can make the bottom surface of the outer shell 11 and the bottom surface of the inner shell plate 13 better fit the ground. After the bottom surface of the outer shell 11 and the bottom surface of the inner shell plate 13 are fitted to the ground, the air in the gap between the inner shell plate 13 and the outer shell 11 is pumped out by starting the vacuum pump 20, and a vacuum is formed in the gap between the inner shell plate 13 and the outer shell 11, so as to achieve the effect of making the present utility model fit the ground more closely.

[0032] In the above embodiments, it should be noted that unscrewing the sealing plug 19 can inject water into the outer shell 11. If the water injected into the outer shell 11 is not full, it is necessary to start the hydraulic push rod 16 to push the pressing plate 17 downward to the water surface to achieve the effect of discharging the air in the outer shell 11, and finally tighten the sealing plug 19.
