[0023] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed by an instrument for detecting the thickness and flatness of concrete pouring, and the layout of the components may also be more complex.

[0024] Some exemplary embodiments of the present invention have been described for illustrative purposes. It should be understood that the present invention may be implemented in other ways not specifically shown in the accompanying drawings.

[0025] Reference Figs. 1-3 An instrument for detecting the thickness and flatness of concrete pouring includes a storage rod 1, which is made of high-strength aluminum alloy, lightweight and corrosion-resistant; the surface is oxidized to enhance wear resistance and impact resistance, making it suitable for harsh construction environments. The side wall of the storage rod 1 has a cover plate 7 for placing batteries. The cover plate 7 has a waterproof sealing structure to ensure that the battery compartment is not affected in a humid environment and to extend the battery life. The edge of the cover plate 7 has a buckle for quick opening and closing, facilitating battery replacement or charging. The lower end of the storage rod 1 has a sliding cavity 12, which has a T-shaped structure to limit the travel of the limiting disc 11. The limiting disc 11 is slidably connected inside the sliding cavity 12, and the lower end of the limiting disc 11 is fixedly installed with a measuring rod 2.

[0026] A linear laser emitter 3 is fixedly installed on the lower section of the side wall of the storage rod 1. The outer side of the measuring rod 2 is equipped with scale lines for measuring length. The scale lines have a wear-resistant coating to ensure clear data reading even after long-term use. The scale line unit is millimeters, with an accuracy of ±0.5mm, meeting high-precision measurement requirements. The length of the head of the measuring rod 2 is 30mm, the middle is 47mm, and the total length is 500mm. The total length of the storage rod 1 is 970mm, with the remaining space used to house the power storage device for the linear laser generator 3. It uses a rechargeable battery + backup battery system, allowing for battery replacement in case of emergency. Two handles 8 are fixedly installed on the upper section of the side wall of the storage rod 1. The outer side of the handles 8 is covered with an anti-slip sleeve 9 made of rubber, providing a comfortable grip and reducing fatigue during prolonged operation. The surface of the anti-slip sleeve 9 has a textured surface to further enhance the anti-slip effect, suitable for operation while wearing gloves. A level bubble 10 for measuring levelness is located at the upper end of the storage rod 1.

[0027] The outer side of the storage rod 1 is provided with a fixing component for fixing the measuring rod 2. The fixing component includes a fixing buckle 6 fixedly installed on the side wall of the storage rod 1. The fixing buckle 6 is connected to a fastening bolt 4 through a pull rope 5. The fastening bolt 4 is threadedly connected to the storage rod 1. The fixing buckle 6 and the pull rope 5 are made of high-strength materials and are highly durable. The surface of the fastening bolt 4 is provided with anti-slip texture, which is easy to tighten manually and ensures that the measuring rod 2 remains stable during use.

[0028] Working principle:

[0029] Insert the measuring rod 2 vertically into the concrete slab and read the concrete thickness value through the scale lines. Ensure the rod is perpendicular to the concrete surface during insertion to avoid measurement errors caused by tilting.

[0030] The level bubble 10 is used to adjust the horizontal state of the measuring rod 2 to ensure the accuracy of the measurement results. The level bubble 10 indicates the horizontal state through gravity, and leveling it can eliminate measurement deviations caused by the tilt of the rod.

[0031] After leveling, tighten the upper fastening bolt 4 to firmly fix the measuring rod 2 and the storage rod 1 to prevent the rod from moving during the measurement process.

[0032] Turn on the linear laser generator 3 and observe the projection of the laser line onto the concrete surface to determine if there are any areas with significant deviations. The linear laser generator 3 emits a straight laser beam, providing a direct view of the smoothness of the concrete surface and facilitating the rapid location of problem areas.
