Description

Technical Field

[0001] This utility model relates to the field of floor slab thickness detection, specifically to a concrete floor slab thickness detection device. Background Technology

[0002] In the construction process, accurate measurement of the thickness of poured concrete slabs is a crucial step in ensuring construction quality. Traditional methods typically involve inserting a metal probe directly into the uncured concrete until it contacts the bottom formwork, then removing the probe. The concrete marks left on the probe's surface are then manually measured using a measuring tape. This method has significant technical drawbacks: First, the concrete marks are often unclear, especially in conditions of high humidity or high concrete slump, making it difficult for surveyors to accurately determine the actual contact point. Second, the probe is prone to skew during insertion, failing to maintain absolute verticality and resulting in distorted measurement data. Third, the entire measurement process requires multiple operations (insertion, withdrawal, measurement), which is not only inefficient but also causes secondary disturbance to the concrete structure with each measurement. Furthermore, existing testing tools lack effective vertical support mechanisms and intuitive reading displays, making on-site testing both time-consuming and inaccurate. These problems severely impact the accuracy and efficiency of construction quality control. Utility Model Content

[0007] Furthermore, this application also proposes that when the sleeve is at the lowest point of the insertion rod, the height between the outer edge of the annular groove and the bottom of the insertion rod is the dimension between the bottom of the scale and the top of the sleeve.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0015] like Figure 1-2 As shown, this application proposes a concrete floor slab thickness detection device, including a sleeve and an insertion rod inserted inside it. A support ring is connected to the bottom of the sleeve, and an annular groove for displaying the highest point of the concrete floor slab is provided on the outside of the support ring. A scale for displaying the thickness of the concrete floor slab is provided on the insertion rod.

[0016] The sleeve can be made of different materials, such as lightweight PVC pipe or metal pipe, and its inner diameter must ensure that the insertion rod can slide smoothly. The support ring and sleeve can be fixed by threaded connection, welding, or integral molding, and its outer diameter must be larger than the outer diameter of the sleeve to form a support surface. The annular groove can be processed into a V-groove, U-groove, or other cross-sectional shape to clearly mark the highest point of the concrete surface. The insertion rod can be made of metal or high-strength plastic, and the scale on its surface can be implemented by laser etching, printing, or adhesive, with a scale accuracy of millimeters.

[0017] The device is stably placed on the concrete surface using a support ring. The insertion rod is inserted vertically to the bottom of the floor slab. The highest point of the concrete surface is where the concrete begins to flow into the annular groove. At this point, the floor slab thickness can be directly obtained by reading the scale value corresponding to the top of the sleeve. Compared to existing technologies, this device achieves simultaneous measurement and reading, avoiding secondary measurement errors. The annular groove design makes the markings on the concrete surface clearer and more legible. The sleeve guide structure effectively prevents the insertion rod from deflecting, improving measurement accuracy. The entire measurement process is simple, quick, and yields accurate and reliable results.

[0018] Furthermore, this application also proposes that the bottom of the insertion rod is provided with a tapered head, and multiple support plates are provided on the outside of the tapered head to keep the insertion rod vertical.

[0019] The conical head is made of metal, with a cone angle ranging from 30° to 60°, preferably 45°. Supporting vertical plates are evenly distributed along the circumference of the conical head, with 3-6 plates, preferably 3. The supporting vertical plates are connected to the conical head by welding or integral molding. The length of the supporting vertical plates ranges from 5-15cm, preferably 8cm. The supporting vertical plates can be made of thin metal sheet or plastic sheet, with a thickness of 1-3mm.

[0020] Specifically, this technical solution effectively solves the problem of easy skewness in existing technologies by setting a conical head and a support plate at the bottom of the insertion rod. The conical head facilitates insertion into the concrete, while the support plate generates a reaction force through contact with the concrete during insertion, automatically correcting the verticality of the insertion rod. Thus, the insertion rod remains vertical during measurement, avoiding measurement errors caused by skewness. Compared with existing technologies, this solution has a simpler structure, is easier to operate, and significantly improves the accuracy of thickness measurement.

[0021] Furthermore, this application also proposes that when the sleeve is at the lowest point of the insertion rod, the height between the outer edge of the annular groove and the bottom of the insertion rod is the dimension between the bottom of the scale and the top of the sleeve.

[0022] Specifically, the height difference between the outer edge of the annular groove and the bottom of the insertion rod is precisely set to be equal to the distance from the bottom of the scale to the top of the sleeve.

[0023] This technical solution establishes a precise height correspondence, allowing the operator to directly read the scale reading from the top of the sleeve when the insertion rod touches the floor slab base, eliminating the need for additional measurement of concrete surface marks. In practice, the combination of a lightweight PVC sleeve and an aluminum alloy annular groove ensures both structural lightness and the accuracy and stability of the annular groove as a measurement reference surface. This design effectively solves the reading difficulties caused by blurred concrete marks in traditional methods, while also eliminating cumulative errors from multiple measurements, significantly improving the accuracy and ease of operation of thickness detection.

[0024] Furthermore, this application also proposes that the sleeve is made of lightweight PVC pipe and the annular groove is made of lightweight aluminum alloy.

[0025] Specifically, lightweight PVC pipes are characterized by their light weight, corrosion resistance, and low cost, which can reduce the overall weight of the testing device, making it easier for operators to carry and use. The annular groove is made of lightweight aluminum alloy, which ensures the strength and wear resistance of the groove while reducing weight.

[0026] Furthermore, this application also proposes that a handle be fixed to the top of the insertion rod.

[0027] By incorporating a handle at the top of the insertion rod, operators can more stably control its vertical insertion, effectively preventing skewing during measurement. This design significantly improves the convenience and stability of the measurement operation, solving the problem of inaccurate measurements caused by easy skewing of the insertion rod in existing technologies. During measurement, operators can complete the entire insertion and reading process by holding the handle with one hand, avoiding the hassle of repeatedly adjusting the insertion rod position required by traditional methods.

[0028] The implementation principle of the concrete floor slab thickness detection device in this application embodiment is as follows:

[0029] When measuring the thickness of the concrete floor slab 9, hold the handle 8 and insert the insertion rod 4 of this device into the concrete floor slab 9. The cone-shaped head 5 at the bottom of the concrete floor slab 9 contacts the bottom template 10. At the same time, multiple support plates 6 realize the vertical positioning of the insertion rod 4.

[0030] Next, hold the sleeve 1, rotate it, and press down the support ring 2. When the external concrete is about to flow into the interior along the outer edge of the annular groove 3, stop pressing down. The edge of the annular groove 3 indicates the height of the concrete floor slab 9. Then, the value read from the scale 7 on the insertion rod 4 is the thickness of the concrete floor slab 9. This test is fast and efficient, and the data is more accurate.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
