Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering quality testing technology, specifically a measuring device for waterproof, anti-corrosion and thermal insulation engineering. Background Technology
[0002] In waterproofing, anti-corrosion and thermal insulation projects, coating thickness is the core indicator that determines the quality and service life of the project. The thickness of the wet coating directly affects the coating coverage and the thickness of the dry film after curing, while the thickness of the dry coating must meet the design standards to ensure that the waterproofing, anti-corrosion and thermal insulation performance meets the standards.
[0003] In actual testing operations, separate tools and equipment are required when measuring dry and wet coatings of waterproof or anti-corrosion coatings: a wet film comb is required for measuring wet film, and a coating thickness gauge and matching test probe are required for measuring dry film. Carrying and switching between multiple tools not only increases the equipment burden on the testing personnel, but also, especially in high-altitude operations (such as wall waterproofing construction), frequent hand switching can easily lead to tools falling and being damaged, and will also prolong the testing time and reduce on-site work efficiency.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a measuring device for waterproof, corrosion-resistant and heat-insulating engineering, in order to achieve a more practical value. Utility Model Content
[0005] The purpose of this invention is to provide a measuring device for waterproof, corrosion-resistant and thermal insulation engineering to solve the problems mentioned in the background art.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A measuring device for waterproof, anti-corrosion, and thermal insulation engineering includes a mounting frame. A square tube is installed inside the mounting frame. Through holes are formed on the top and bottom surfaces of one end of the square tube. A branch pipe is installed inside a pair of through holes. A detection probe is installed inside one end of the branch pipe. A coating thickness gauge is installed on the outer wall of the square tube. The input end of the coating thickness gauge is electrically connected to the detection probe via a wire. Circular holes are formed on the top and bottom surfaces of the square tube at the end furthest from the coating thickness gauge. A screw is installed inside a pair of circular holes. A slot is formed at one end of the screw. A wet film comb is installed inside the slot. The wet film comb is toothed at the end furthest from the screw.
[0007] The beneficial effect of adopting the above-mentioned further solution is that by integrating the wet film comb and coating thickness gauge in a square tube, the thickness of dry and wet coatings can be measured in an integrated manner. During construction, the toothed wet film comb is first inserted into the uncured wet coating to read the wet film thickness (controlling the coating coverage rate); after the coating has cured, the detection probe is used in conjunction with the coating thickness gauge to measure the dry film thickness (verifying the final quality). There is no need to carry multiple tools, which greatly improves the efficiency of on-site inspection. The structural design of the square tube makes the components of the two measurement functions compact, and the operation can be switched by simply holding the square tube, which is especially suitable for waterproof and anti-corrosion construction inspection scenarios in high-altitude and confined spaces.
[0008] Furthermore, the wet film comb has a tooth spacing of 10-50μm and a tooth height range of 50-500μm at the end away from the screw. The wet film comb is made of stainless steel and its surface is passivated.
[0009] The advantages of adopting the above-mentioned further solution are that the tooth spacing and tooth height range accurately cover the commonly used wet film thickness range (50-500μm) in waterproof and anti-corrosion engineering, ensuring that wet coatings of different thicknesses can be accurately read by immersing the tooth height; the stainless steel material and surface passivation treatment give the wet film comb strong corrosion resistance, which can be used for a long time in acid and alkali coatings and solvent environments, avoiding tooth surface corrosion that leads to blurred scale. At the same time, the high hardness of stainless steel and the non-deformable tooth structure ensure the long-term stability of measurement accuracy, making it suitable for high-frequency, multi-batch coating thickness testing needs.
[0010] Furthermore, the wet film comb has a first screw hole at the center of the inner part near the end of the screw, and the screw has second screw holes on both sides of the inner part near the slot. A bolt is threaded between the first screw hole and the two second screw holes, and the two ends of the bolt are respectively located in the two second screw holes.
[0011] The advantages of adopting the above-mentioned further solution are that the bolt connection method allows for quick disassembly and assembly of the wet film comb. When a certain comb tooth is worn or a wet film comb with a different range needs to be replaced, the replacement can be completed simply by unscrewing the bolt, without having to replace the entire measuring device, thus reducing maintenance costs. The first screw hole, the second screw hole, and the bolt work together to ensure a stable connection between the wet film comb and the screw rod. During measurement, the wet film comb will not shift due to vibration or resistance when inserting the wet film, ensuring accurate readings.
[0012] Furthermore, the top and bottom surfaces of the square tube are provided with transverse grooves on both sides of the circular hole, and the wet film comb is located in the transverse grooves, with the outer wall of the wet film comb slidingly engaged with the inner wall of the transverse groove.
[0013] The beneficial effects of adopting the above-mentioned further solution are that the transverse groove provides guidance for the movement of the wet film comb, ensuring that the wet film comb remains vertical when inserted into the wet coating, avoiding measurement errors in wet film thickness caused by tilting; the sliding fit structure allows the wet film comb to be stored in the transverse groove when not measuring, preventing the tooth surface from being bumped and damaged, while keeping the device clean and easy to carry and store.
[0014] Furthermore, the screw is externally threaded with a nut, the bottom surface of which is in contact with the top surface of the square tube at the end furthest from the coating thickness gauge.
[0015] The beneficial effect of adopting the above-mentioned further solution is that the nut is connected to the screw thread through the thread preload, and the extension length of the wet film comb can be adjusted according to the testing requirements (for example, when a thick coating needs to be measured in depth, the nut can be loosened to adjust the position of the screw before tightening it to fix it), which is suitable for wet film measurement scenarios with different thicknesses and different construction surfaces (walls / grounds).
[0016] Furthermore, there is a gap between the bottom end of the wet film comb and the bottom end of the detection probe.
[0017] The beneficial effects of adopting the above-mentioned further scheme are that the wet film comb works independently when measuring wet film, and the detection probe works independently when measuring dry film. There is a gap between the wet film comb and the construction surface, which improves the smoothness and safety of the measurement process.
[0018] Furthermore, the branch pipe has a wire groove on its outer wall at the end away from the detection probe, and the wire is located in the wire groove.
[0019] The beneficial effect of adopting the above-mentioned further solution is that the wire groove makes the wire layout neat and locates the wire direction.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This measuring device for waterproof, anti-corrosion and thermal insulation engineering integrates a wet film comb and a coating thickness gauge in a square tube, realizing integrated measurement of dry and wet coating thickness. During construction, the toothed wet film comb is first inserted into the uncured wet coating to read the wet film thickness (controlling the coating coverage rate); after the coating is cured, the detection probe is used in conjunction with the coating thickness gauge to measure the dry film thickness (verifying the final quality). There is no need to carry multiple tools, which greatly improves the efficiency of on-site inspection. The structural design of the square tube makes the components of the two measurement functions compact, and the switching can be completed by simply holding the square tube during operation. It is especially suitable for waterproof and anti-corrosion construction inspection scenarios in high-altitude and confined spaces. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-5 This utility model provides a technical solution: a measuring device for waterproof, anti-corrosion, and thermal insulation engineering, including a mounting frame 1, a square tube 2 installed inside the mounting frame 1, through holes 3 on the top and bottom surfaces of one end of the square tube 2, a branch pipe 4 installed inside the pair of through holes 3, a detection probe 5 installed inside one end of the branch pipe 4, a coating thickness gauge 7 installed on the outer wall of the square tube 2, and the input end of the coating thickness gauge 7 electrically connected to the detection probe 5 via a wire; the top and bottom surfaces of the square tube 2 at the end away from the coating thickness gauge 7... Each surface has a circular hole 8, and a screw 9 is installed inside a pair of circular holes 8. A slot 11 is opened at one end of the screw 9, and a wet film comb 12 is installed inside the slot 11. The wet film comb 12 is toothed at the end away from the screw 9. During construction, the toothed wet film comb 12 is first inserted into the uncured wet coating to read the wet film thickness (to control the coating coverage). After the coating is cured, the dry film thickness is measured with the detection probe 5 and the coating thickness gauge 7 (to verify the final quality). There is no need to carry multiple tools, which greatly improves the efficiency of on-site inspection.
[0025] The wet film comb 12 has a tooth spacing of 10-50μm and a tooth height range of 50-500μm at the end furthest from the screw 9. The wet film comb 12 is made of stainless steel and its surface is passivated. The tooth spacing and tooth height range accurately cover the commonly used wet film thickness range (50-500μm) in waterproof and anti-corrosion engineering, ensuring that wet coatings of different thicknesses can be accurately read by immersing the tooth height. The stainless steel material and surface passivation treatment give the wet film comb 12 strong corrosion resistance, allowing it to be used for a long time in acid and alkali coatings and solvent environments, avoiding tooth surface corrosion that could cause the scale to become blurred.
[0026] The wet film comb 12 has a first screw hole 14 at the center of its interior near the end of the screw 9. The screw 9 has second screw holes on both sides of its interior near the end of the slot 11. A bolt 15 is threaded between the first screw hole 14 and the two second screw holes, with the two ends of the bolt 15 located in the two second screw holes respectively. The bolt 15 connection method allows the wet film comb 12 to be quickly disassembled and assembled. When a comb tooth is worn or a wet film comb 12 with a different range needs to be replaced, the replacement can be completed by simply unscrewing the bolt 15, without having to replace the entire measuring device.
[0027] The square tube 2 has horizontal grooves 13 on both sides of the circular hole 8 on its top and bottom surfaces. The wet film comb 12 is located in the horizontal grooves 13, and the outer wall of the wet film comb 12 slides in fit with the inner wall of the horizontal groove 13. The sliding fit between the horizontal groove 13 and the wet film comb 12 allows the wet film comb 12 to be stored in the horizontal groove 13 when not measuring, preventing the tooth surface from being damaged by bumps.
[0028] The screw 9 is externally threaded with a nut 10, and the bottom surface of the nut 10 is in contact with the top surface of the square tube 2 at the end away from the coating thickness gauge 7.
[0029] There is a gap between the bottom end of the wet film comb 12 and the bottom end of the detection probe 5. When measuring the thickness of the dry coating, the detection probe 5 is in contact with the coating. Since there is a gap between the bottom end of the wet film comb 12 and the bottom end of the detection probe 5 (the wet film comb 12 is away from the dry coating and the detection probe 5 is close to the dry coating), the wet film comb 12 is not in contact with the dry coating at this time. When measuring the wet coating, the wet film comb 12 slides out from the transverse groove 13, and there is a gap between its bottom end and the bottom end of the detection probe 5 (the wet film comb 12 is close to the wet coating and the detection probe 5 is away from the wet coating). At this time, the detection probe 5 is not in contact with the wet coating.
[0030] Among them, the branch pipe 4 has a wire groove 6 on the outer wall at the end away from the detection probe 5, and the wire is located in the wire groove 6.
[0031] Specifically, the working principle of this measuring device for waterproof, anti-corrosion, and thermal insulation engineering is as follows: When using it, first select the measuring function according to the type of coating to be tested (wet film or dry film). If testing the wet film thickness, first confirm whether the tooth spacing and tooth height of the wet film comb 12 are suitable for the current coating (e.g., if the wet film thickness of the waterproof coating is expected to be 100-300μm, a wet film comb 12 with a tooth height covering this range can be selected). If the wet film comb 12 needs to be replaced, unscrew the bolt 15, remove the old wet film comb 12 from the slot 11 of the screw 9, and replace it with a new wet film comb 12. Align the first screw hole 14 with the second screw hole and screw in the bolt 15 to secure it; then loosen the nut 10 and adjust the extension length of the screw 9 in the round hole 8 of the square tube 2 so that the toothed end of the wet film comb 12 can be vertically inserted into the wet coating. After adjustment, tighten the nut 10 to secure the screw 9; holding the square tube 2, slide the wet film comb 12 along the transverse groove 13 to extend it and vertically insert it into the uncured wet coating. The insertion depth should be such that the toothed end completely contacts the bottom surface of the coating. After removal, observe the height of the wetted teeth and read the wet film thickness. After completion, slide the wet film comb 12 back into the transverse groove 13. If measuring the dry film thickness, there is no need to operate the wet film comb 12. Simply hold the square tube 2 and align the detection probe 5 with the cured dry coating surface, ensuring that the detection probe 5 is perpendicular to and in contact with the coating. The coating thickness gauge 7 receives the signal from the detection probe 5 through the wire and displays the dry film thickness value in real time. During the measurement process, when measuring the dry coating thickness, the detection probe 5 is in contact with the coating. Because there is a gap between the bottom end of the wet film comb 12 and the bottom end of the detection probe 5 (the wet film comb 12 is away from the dry coating and the detection probe 5 is close to the dry coating), at this time the wet film comb 12 is not in contact with the dry coating. Coating contact; when measuring a wet coating, the wet film comb 12 slides out from the transverse groove 13, and there is a gap between its bottom end and the bottom end of the detection probe 5 (the wet film comb 12 is closer to the wet coating detection probe 5 and farther away from the wet coating). At this time, the detection probe 5 does not contact the wet coating, ensuring that the two measurement functions do not interfere with each other and avoiding collision damage to components. Throughout the process, the integrated design of the square tube 2 makes the dry and wet film measurement tools compact. The two measurement functions can be switched by simply holding the square tube 2, which greatly improves the efficiency of on-site coating thickness detection in waterproof, anti-corrosion and thermal insulation projects.
[0032] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
