Description

Technical Field

[0001] This utility model belongs to the field of building measurement technology, and specifically relates to a wall thickness measuring instrument. Background Technology

[0002] Building codes have clear standards for wall thickness. For example, the thickness of load-bearing walls is usually between 15 and 30 cm; the thickness of exterior walls can reach 20 to 30 cm because they need to withstand wind and rain erosion. The measurement data must be strictly matched with the design requirements to ensure structural strength and durability. The wall thickness directly affects the load-bearing capacity, resistance to lateral displacement and stability of the structure. Walls that are too thin may lead to instability or deformation, affecting building safety; walls that are too thick may increase material consumption and construction difficulty. Therefore, accurate measurement of building wall thickness is crucial for building construction.

[0003] The same wall may require multiple measurement points. The average of these measurements is used to more accurately reflect the wall's thickness. The most basic measurement method is manual measurement using measuring tools such as tape measures, which is not accurate enough. Existing technologies include wall measuring devices that fit against both sides of the wall, holding the wall in place, and then reading the thickness using a scale on the device. Alternatively, an ultrasonic measuring instrument can be installed on the device to directly measure the wall thickness using ultrasound. However, all of these devices have a problem: when taking multiple measurements from the bottom to the top of the wall, the device needs to be manually removed and repositioned at another point, which is very cumbersome. This manual selection of measurement points cannot cover all points from the bottom to the top of the wall, and some points may be overlooked due to thickness anomalies caused by poor construction quality. Summary of the Invention

[0004] This utility model provides a wall thickness measuring instrument. The measuring instrument is attached to the two sides of the wall on both sides and is fixed to the wall as a whole. The inner side of the device is provided with a structure adapted to be pushed and rolled on the wall. The device can be pushed to move from the bottom to the top of the wall. The wall thickness is measured during the movement of the device. The measurement path is the pushing path, which can fully cover all points on the wall from bottom to top. This makes the measurement data sample library more complete and the final mean value more accurate.

[0005] To achieve the above-mentioned technical objectives, this utility model is implemented through the following technical solution: A wall thickness measuring instrument, comprising: The first clamping part has its inner side surface attached to one side of the wall. The second clamping part has its inner side surface attached to the other side of the wall.

[0006] Preferably, at least two sets of the inner rollers are provided on the inner side of the clamping part; Each set of inner rollers has a mounting groove on the inner side of the clamping part, and the inner rollers are rotatably mounted in the mounting groove via the wheel axle core rod.

[0007] Preferably, both the first clamping part and the second clamping part are provided with hinge seats at their rear ends; The hinge seat is equipped with a hinge pivot rod; The hinge pivot rod is provided with a push support rod at its first end.

[0008] Preferably, the connection component includes: A screw, the first end of which is disposed on a first clamping part; the second end of which passes through a through hole opened on a second clamping part and is movably disposed between the screw and the second clamping part; Fastening bolts are movably mounted on the screw rod via threaded engagement.

[0009] Preferably, an ultrasonic transmitting probe is provided on the outer side of the second clamping part; An ultrasonic receiving probe is provided on the outer side of the first clamping part; The ultrasonic receiving probe is communicatively connected to the processor terminal.

[0010] Preferably, a plurality of sets of outer rollers are provided on the outer surfaces of the first clamping part and the second clamping part; The outer roller includes roller mounting seats symmetrically arranged on both sides, and the roller is rotatably set between the two sets of roller mounting seats via a rotating shaft.

[0011] The beneficial effects of this utility model are: The wall thickness measuring instrument provided by this utility model uses the inner surfaces of the first and second clamping parts to adhere to the wall surface, clamping the wall and then measuring its thickness. Inner rollers are provided on the inner surfaces of both the first and second clamping parts that contact the wall surface, allowing the entire measuring device to be moved along the wall during measurement. All points along the path traveled by the measuring device can be measured. Compared to existing measuring instruments, it eliminates the need for installation and measurement at each point, and the collected measurement sample data is more comprehensive and complete, resulting in a more accurate average value. The outer surfaces of the second clamping part and the first clamping part are respectively equipped with an ultrasonic transmitting probe and an ultrasonic receiving probe. For walls between two rooms where the measuring instrument cannot clamp, the wall thickness can be measured by attaching the first clamping part and the second clamping part to the walls on both sides, using ultrasonic waves. This makes the measuring instrument applicable to a wider range of scenarios. Attached Figure Description

Detailed Implementation

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 like Figure 1 As shown, a wall thickness measuring instrument includes: a first clamping part 1 and a second clamping part 2. The inner surfaces of the first clamping part 1 and the second clamping part 2 are attached to the two sides of the wall and clamped to the wall. A connecting component is provided near the rear end of the first clamping part 1 and the second clamping part 2 to connect the two clamping parts. The second clamping part 2 can move on the connecting component to adjust the distance between the first clamping part 1 and the second clamping part 2 according to the wall thickness. like Figure 1 As shown, the connecting assembly includes: a screw 3 and a fastening bolt 4; the first end of the screw 3 is disposed on the first clamping part 1, and the second end of the screw 3 passes through a through hole opened on the second clamping part 2, allowing the second clamping part 2 to move on the screw 3; a fastening bolt 4 is disposed near the second end of the screw 3 and on the screw 3, with a threaded engagement between the fastening bolt 4 and the screw 3; when the distance between the first clamping part 1 and the second clamping part 2 is adjusted to be able to clamp the wall, the fastening bolt 4 is tightened, so that the two clamping parts exert a certain clamping force on the wall, but without hindering the movement of the entire device on the wall; Hinges 5 are provided at the rear ends of both the first clamping part 1 and the second clamping part 2, such as... Figure 5 As shown, a hinge pivot rod 501 is provided inside the hinge seat 5, and one end of the push support rod 6 is connected to the hinge pivot rod 501. The structural principle of the hinge pivot rod 501 is the same as that of the pivot rod on the existing component hinge. Due to the presence of the hinge pivot rod 501, the push support rod 6 has a degree of rotational movement relative to the hinge seat 5; the measuring instrument can be moved up and down on the wall by pushing the push support rod 6. like Figure 2As shown, a laser reflector 8 and a laser rangefinder 7 are respectively provided on the inner sides of the first clamping part 1 and the second clamping part 2, and near the rear ends of the first clamping part 1 and the second clamping part 2, to measure the wall thickness using the laser rangefinder principle; laser rangefinder is an existing technology, and its principle and component composition will not be described in detail. To facilitate moving the entire measuring instrument along the wall, such as Figure 2 As shown, inner rollers 9 are provided on the inner surfaces of both the first clamping part 1 and the second clamping part 2. Multiple sets of inner rollers 9 can be provided on the clamping part to achieve stable pushing and minimize pushing resistance. In this embodiment, two sets of inner rollers 9 are vertically provided on each clamping part, and the inner rollers 9 are set close to the front end of the clamping part. Each set of inner rollers 9 has a mounting groove at the mounting position on the inner surface of the clamping part. The inner rollers are rotatably mounted in the mounting groove through the wheel axle core rod. The inner rollers 9 protrude a portion of the inner surface of the clamping part. The height of this portion of the inner rollers 9 protruding from the inner surface of the clamping part is equal to the thickness of the laser rangefinder 7 and the laser reflector 8. When the measuring instrument clamps the wall, the inner rollers 9 are actually in contact with the wall. At this time, the distance between the laser rangefinder 7 and the laser reflector 8 is exactly the wall thickness, ensuring accurate measurement results. When adjusting the measuring instrument to be clamped to the wall, care should be taken to avoid the wall obstructing the laser rangefinder 7 and the laser reflector 8, and the clamping position should not be too far back relative to the measuring instrument. After clamping, measurement can begin. By pushing the support rod 6, the measuring instrument is moved from bottom to top or from top to bottom on the wall, and the wall thickness is measured during the movement. Data from all points the measuring instrument passes through can be collected, avoiding the omission of abnormal points, and the sample data is sufficient and completely covered, which helps to improve the accuracy of the final average wall thickness measurement. When using the measuring instrument provided in this embodiment for multi-point measurement, there is no need to disassemble and install the measuring instrument at each point, making the measurement more continuous and faster.

[0017] Example 2 Based on Example 1, the measuring instrument structure provided in Example 1 is suitable for situations where the wall has an open side, such as unfinished building walls or walls at door frames, where it is easy to clamp and measure on the open side; however, for finished buildings, the partition wall between two independent rooms usually does not have an open side, and in this case, it is impossible to measure the wall thickness by clamping. This embodiment is based on the measuring instrument structure of Embodiment 1, and adds an ultrasonic measuring element, making it suitable for measuring walls without an open side; like Figure 3As shown, an ultrasonic transmitting probe 10 is centrally located on the outer side of the second clamping part 2, and an ultrasonic receiving probe 11 is centrally located on the outer side of the first clamping part 1; the ultrasonic receiving probe 11 is communicatively connected to the processor terminal; using ultrasonic waves for thickness measurement is existing technology, and its component structure and principle will not be described in detail here. During measurement, the outer surfaces of the first clamping part 1 and the second clamping part 2 are respectively attached to the two sides of the wall; the ultrasonic transmitting probe 10 and the ultrasonic receiving probe 11 are aligned. The alignment of the two sets of probes can be determined according to the positioning coordinates. For example, the wall is used as the coordinate plane, and the positioning point can be determined by the horizontal distance and the vertical distance. The two sets of probes can be aligned after moving to the same positioning point. The two clamping parts move on the wall, also propelled by the pushing strut 6. To reduce the pushing resistance, such as... Figure 3 As shown, outer rollers 12 are provided on the outer surfaces of both the first clamping part 1 and the second clamping part 2. The outer rollers 12 are arranged in a row on each side of the ultrasonic transmitting probe 10 and the ultrasonic receiving probe 11, and several sets of outer rollers are arranged on each row. In this embodiment, three sets of outer rollers are arranged in the same row on the outer surface of the second clamping part 2, and four sets of outer rollers are arranged in the same row on the outer surface of the first clamping part 1. like Figure 6 As shown, the outer roller 12 structure includes roller mounting seats 1202 symmetrically arranged on both sides, and the roller 1201 is rotatably arranged between the two sets of roller mounting seats 1202 via a rotating shaft. The overall height of the outer roller 12 on the outer side of the first clamping part 1 is equal to the thickness of the ultrasonic receiving probe 11; the overall height of the outer roller 12 on the outer side of the second clamping part 2 is equal to the thickness of the ultrasonic transmitting probe 10; this ensures that when the outer sides of the first clamping part 1 and the second clamping part 2 are in contact with the wall, the two sets of ultrasonic probes are also in contact with the wall.
