[0034] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] This utility model provides a device for detecting the thickness of concrete pouring, comprising: a support unit 100, consisting of a triangular bracket 110 and a telescopic rod 120, the telescopic rod 120 being a telescopic hollow cylindrical structure with a vertical pointer 121 on the rod; a measuring unit 200, installed at the top of the telescopic rod 120, used to monitor the concrete surface height in real time and calculate the pouring thickness; and an alarm unit 300, signal-connected to the measuring unit 200, used to trigger different alarm modes based on the concrete pouring thickness measured by the measuring unit 200.

[0036] The support unit 100 consists of a triangular bracket 110 and a telescopic hollow cylindrical rod. The triangular bracket 110 is hinged to the bottom of the telescopic rod 120, and a measuring unit 200 is installed at the top of the telescopic rod 120. The measuring unit 200 collects real-time data on the height of the concrete surface and calculates the difference between the measured height and the design thickness using a built-in algorithm. The alarm unit 300 receives the signal from the measuring unit 200 via a wireless receiving module (such as Bluetooth) and triggers an audible and visual alarm. The triangular bracket 110 provides three-point stable support, and the telescopic rod 120 achieves length adjustment through nested segments.

[0037] The three-unit collaboration enables full automation of the measurement-calculation-alarm process, achieving integrated design. It is suitable for environments with dense reinforcement or complex formwork, reducing manual intervention and improving adaptability.

[0038] For example, the telescopic rod 120 is made of spirally wound stainless steel strip, with adjacent sections locked by snap-fit ​​fasteners; or it is made of ABS plastic sheet, hot-pressed, with sections tightened by threads. The metal material enhances bending strength, while the plastic material reduces weight; the telescopic structure uses a spring to assist in retraction. The retracted volume is reduced by more than 50%, facilitating transportation. The metal material is corrosion-resistant, and the plastic material is low-cost.

[0039] In one embodiment, the measurement unit 200 includes a measurement sensor 210 and a signal sensor 220. The measurement sensor 210 is a laser rangefinder or an ultrasonic sensor, and the signal sensor 220 transmits the data measured by the measurement sensor 210 to the alarm unit 300.

[0040] For example, the sensor uses an industrial-grade laser rangefinder, and signal transmission is processed through integrated circuit board.

[0041] In one embodiment, the triangular bracket 110 is a detachable or foldable structure for fixing the device in a reinforced environment.

[0042] The 110-foot tripod is foldable, with the unfolded angle secured by pins; alternatively, it can be attached to rebar using a magnetic base. The folding structure allows for opening and closing from 0-90° via hinges, and the magnetic base contains built-in neodymium magnets. No additional tools are needed when working through rebar mesh, and deployment can be completed in 3 seconds. The folded design reduces thickness, making it easy to store in confined spaces.

[0043] In one embodiment, the vertical pointer 121 is used to calibrate the perpendicularity of the telescopic rod 120 to the template, thereby reducing measurement errors.

[0044] The vertical pointer 121 is a gravity hammer structure, suspended in a groove on the side of the telescopic rod 120; or it can be an electronic level integrated into the rod body. The mechanical pointer indicates verticality by swinging; the electronic level indicates tilt status via an LED light. The verticality error is <0.5°, ensuring the reliability of the measurement data.

[0045] In one embodiment, the measuring unit 200 signals the sensor 220 and generates at least one of the following signals by measuring the difference between the concrete pouring surface and the design value by the measuring sensor 210: a thickness almost reaching the standard signal, i.e., the thickness is less than the design value by 15-20 cm; a thickness reaching the standard signal, i.e., the thickness is equal to the design value; and a thickness exceeding the standard signal, i.e., the thickness is greater than the design value.

[0046] The sensor has preset thresholds: when the measured value equals the design value minus 20cm, it outputs a near-compliance signal; when the measured value equals the design value, it outputs a compliance signal; and when the measured value exceeds the design value, it outputs an exceedance signal. This provides advance notice to construction personnel to adjust the pouring speed and avoid excessive waste. The signal sensor 220 is a wireless transmission module that sends data to the alarm unit 300 or a mobile terminal.

[0047] In one embodiment, the alarm unit 300 includes an audible and visual alarm device 310 and a signal receiver 320, the signal receiver 320 receiving signals sent by the signal sensor 220. The audible and visual alarm device 310 of the alarm unit 300 performs the following actions based on the received signals: a yellow light flashes when the thickness is close to the target; a green light flashes and three beeps sound when the thickness meets the target; and a red light flashes and a continuous, rapid beeping sound sounds when the thickness exceeds the target.

[0048] The audible and visual alarm device 310 uses a combination of three-color LED lights 311 (red / yellow / green) and a horn 312, controlled by a relay. The red light flashes at a high frequency (5Hz), the green light flashes intermittently (1Hz), and the horn 312 has an adjustable volume. This dual audible and visual alert is suitable for noisy construction site environments.

[0049] In one embodiment, the telescopic rod 120 has a telescopic range of 0.5m to 3m to accommodate large-volume concrete pouring scenarios.

[0050] The 120mm telescopic pole has a minimum retracted length of 0.5m and a maximum extended length of 3m, with segments positioned by elastic pins. It covers concrete thickness requirements ranging from thin to thick slabs.

[0051] In one embodiment, the measurement accuracy of the measuring sensor 210 is ±1 mm. A sensor with ±1 mm accuracy is selected, and random errors are reduced by averaging multiple samples.

[0052] In one embodiment, the legs of the triangular bracket 110 are provided with anti-slip pads 111 to enhance the stability of the device on the template.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
