Description

Technical Field

[0001] This utility model belongs to the technical field of testing devices, specifically relating to a tool for testing the thickness of concrete floor slabs. Background Technology

[0002] Concrete slab thickness testing is the process of measuring and inspecting the actual thickness of concrete slabs in a building. Slab thickness is a crucial factor affecting the structural load-bearing capacity and stability of a building. Appropriate thickness ensures that the slab will not undergo excessive deformation or damage when bearing its own weight, service loads, and potential dynamic loads, thus guaranteeing the structural safety of the building.

[0003] Patent document CN215676798U discloses a simple tool for detecting the thickness of concrete pouring in floor slabs. The tool includes a main body with a slide rail at its top. One end of the slide rail is recessed downwards. A sliding ring is nested in the outer wall of the main body. A connecting rod is fixedly installed on the inner wall of the sliding ring. A turntable is movably installed at the bottom of the connecting rod, and another turntable is movably installed at one end of the connecting rod. The turntable is installed inside the slide rail. Simultaneously, when the sliding ring moves, it drives the connecting rod to move, and the movement of the connecting rod causes the turntable to rotate inside the slide rail. This reduces friction and facilitates the sliding of the sliding ring on the outer wall of the main body, greatly improving the operator's work efficiency and reducing the workload of the workers.

[0004] The aforementioned device greatly improves the work efficiency of operators and reduces the workload of staff. However, when using the device, after the traditional testing tool completes the test, the probe surface is often covered with a large amount of concrete. The cleaning process is cumbersome, time-consuming, and may lead to probe corrosion and wear due to incomplete cleaning, shortening the tool's service life and increasing maintenance costs. Therefore, a new type of concrete slab thickness testing tool is needed to improve the aforementioned device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a concrete slab thickness detection tool. It features a vertical guide rail and inner slider for precise guidance, ensuring the cylindrical measuring probe moves vertically to the bottom of the slab. Combined with a scale at the front end of a square external hollow tube, it accurately reads the thickness data of the poured concrete slab, effectively avoiding measurement errors. This solution addresses the problem of traditional detection tools where a large amount of concrete often adheres to the probe surface after testing, making cleaning cumbersome, time-consuming, and potentially leading to probe corrosion and wear due to incomplete cleaning, shortening tool lifespan and increasing maintenance costs.

[0006] To achieve the above-mentioned precise guidance via vertical guide rail and inner slider, ensuring that the cylindrical measuring probe moves vertically downward to the bottom of the floor slab, and in conjunction with the scale at the front end of the square outer hollow tube, the thickness data of the concrete floor slab can be accurately read, effectively avoiding measurement errors, this utility model provides the following technical solution: a concrete floor slab thickness detection tool, including a detection component, a handle component provided on the inner side of the detection component, a flushing component provided on the upper end of the detection component, and an auxiliary component provided inside the detection component;

[0007] The detection assembly includes a square outer hollow tube, a scale is fixedly connected to the left front end of the square outer hollow tube, a vertical guide rail is fixedly connected to the inner rear wall of the square outer hollow tube, an inner slider is installed on the vertical guide rail, a cylindrical measuring probe is fixedly connected to the front end of the inner slider, a bottom expansion plate is fixedly connected to the lower end of the square outer hollow tube, and a front opening is opened at the front end of the square outer hollow tube.

[0008] The rinsing assembly includes a first ring, which is located inside the lower part of a square outer hollow tube. Multiple pressurized nozzles are fixedly connected to the upper end of the first ring. A water top tank is fixedly connected to the upper end of the square outer hollow tube. Multiple hoses are provided at the output end of the water top tank, and the multiple hoses are interconnected with the corresponding pressurized nozzles.

[0009] Furthermore, multiple pressurized nozzles are arranged in a ring at equal intervals, with the multiple pressurized nozzles located outside the cylindrical measuring probe.

[0010] Furthermore, the grip assembly includes a rotating connector mounted above the front end of the cylindrical measuring probe.

[0011] Furthermore, an extension handle is rotatably connected to the front end of the rotating connector, and a spur bolt is installed at the upper end of the extension handle.

[0012] Furthermore, the auxiliary component includes a second ring, which is located above the first ring.

[0013] Furthermore, a metal inner ring is fixedly connected to the inner end of the second ring, and multiple springs are fixedly connected to the inner end of the metal inner ring.

[0014] Furthermore, an electromagnetic arc-shaped plate is fixedly connected to the end of one of the multiple springs away from the inner metal ring, and a wiping inner plate is fixedly connected to the end of the electromagnetic arc-shaped plate away from the spring.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. When in use, this utility model uses a vertical guide rail and an inner slider to precisely guide the cylindrical measuring probe to move vertically down to the bottom of the floor slab. With the scale at the front end of the square outer hollow tube, the thickness data of the concrete floor slab can be accurately read, effectively avoiding measurement errors. The extended grip of the handle assembly cooperates with the rotating connector to facilitate adjustment of the grip angle. Construction personnel can quickly and stably push the probe to complete the measurement operation.

[0017] 2. In use, this utility model consists of an automatic flushing system formed by the water tank at the top of the flushing component, the hose, the first ring, and the pressurized nozzle. Pressurized water is sprayed from multiple angles, which can efficiently remove concrete deposits from the surface of the cylindrical measuring probe. The auxiliary component automatically dries the residual sewage on the probe surface by de-energizing the electromagnetic arc plate and driving the spring force to wipe the inner plate, thereby reducing the corrosion and wear of the probe by concrete, extending the service life of the tool, and reducing maintenance costs.

[0018] 3. In use, the extended handle in the handle assembly can be rotated and folded around the rotating connector, and then fixed with a claw bolt, effectively reducing the overall size of the tool and making it convenient for construction workers to carry and store. In the limited space of the construction site, this storage design improves the portability of the tool, making it easy to access at any time and enhancing its ease of use.

[0027] 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.

[0028] Please see Figures 1 to 5 The present invention provides a technical solution: a concrete floor slab thickness detection tool, including a detection component 1, a handle component 2 provided on the inner side of the detection component 1, a flushing component 3 provided on the upper end of the detection component 1, and an auxiliary component 4 provided inside the detection component 1.

[0029] The detection component 1 includes a square outer hollow tube 100. A scale 105 is fixedly connected to the left front end of the square outer hollow tube 100. A vertical guide rail 102 is fixedly connected to the inner rear wall of the square outer hollow tube 100. An inner slider 103 is installed on the vertical guide rail 102. A cylindrical measuring probe 104 is fixedly connected to the front end of the inner slider 103. A bottom expansion plate 106 is fixedly connected to the lower end of the square outer hollow tube 100. A front opening 107 is opened at the front end of the square outer hollow tube 100.

[0030] The rinsing assembly 3 includes a first ring 301, which is located inside the lower part of the square outer hollow tube 100. Multiple pressurized nozzles 302 are fixedly connected to the upper end of the first ring 301. A water top tank 300 is fixedly connected to the upper end of the square outer hollow tube 100. Multiple hoses are provided at the output end of the water top tank 300, and the multiple hoses are interconnected with the corresponding pressurized nozzles 302.

[0031] like Figure 2 , Figure 4As shown, multiple pressurized nozzles 302 are arranged in a ring at equal intervals. The multiple pressurized nozzles 302 are located outside the cylindrical measuring probe 104. The handle assembly 2 includes a rotating connector 200, which is installed above the front end of the cylindrical measuring probe 104. An extension handle 201 is rotatably connected to the front end of the rotating connector 200, and a spur bolt 202 is installed at the upper end of the extension handle 201.

[0032] It should be noted that the extended grip 201 in the grip assembly 2 can be rotated and folded around the rotating connector 200 and then fixed by the spur bolt 202, which effectively reduces the overall size of the tool and makes it convenient for construction personnel to carry and store. In the environment of limited space on the construction site, this storage design improves the portability of the tool, makes it easy to access at any time, and enhances the convenience of use.

[0033] like Figure 2-3 As shown, the auxiliary component 4 includes a second ring 401, which is located above the first ring 301. A metal inner ring 402 is fixedly connected to the inner end of the second ring 401. A plurality of springs 403 are fixedly connected to the inner end of the metal inner ring 402. An electromagnetic arc plate 404 is fixedly connected to the end of the plurality of springs 403 away from the metal inner ring 402. A wiping inner plate 405 is fixedly connected to the end of the electromagnetic arc plate 404 away from the springs 403.

[0034] It should be noted that the auxiliary component 4 automatically wipes the residual sewage on the probe rod surface by de-energizing the electromagnetic arc plate 404 and driving the inner plate 405 with the elastic force of the spring 403, thereby reducing the corrosion and wear of the probe rod by the concrete, extending the tool's service life, and reducing maintenance costs.

[0035] The working principle of the above embodiment is as follows: The construction worker holds the extended handle 201 in the handle assembly 2. The extended handle 201 is connected to the upper front end of the cylindrical measuring probe 104 via the rotating connector 200, allowing for flexible adjustment of the grip angle. The testing tool is placed on the surface of the pre-formed concrete slab. The bottom expansion plate 106 increases the contact area with the concrete, ensuring the tool's stability. Then, the extended handle 201 is pushed downwards, moving the cylindrical measuring probe 104. Since the vertical guide rail 102 is fixed to the rear inner wall of the square outer hollow tube 100, its output end's inner slider 103 is fixedly connected to the front end of the cylindrical measuring probe 104. The vertical guide rail 102 and the inner slider 103 cooperate to provide precise guidance for the movement of the cylindrical measuring probe 104, allowing it to move vertically downwards until the bottom of the probe touches the bottom of the concrete slab. Once the cylindrical measuring probe 104 reaches the bottom of the slab, the construction workers stop pushing it. At this point, by observing the depth of concrete adhesion on the cylindrical measuring probe 104 and comparing it with the scale 105 fixedly connected to the left side of the front end of the square outer hollow tube 100, the thickness data of the concrete slab is obtained. The scale 105 has clearly marked graduations, meeting the needs of different precision measurements and ensuring the accuracy of data reading, thus completing the thickness measurement. Afterwards, the flushing assembly 3 is activated, and the pump in the top water tank 300 starts working, delivering the water in the tank through multiple hoses at the output end to the pressure nozzles 302 arranged in a ring at equal intervals on the upper end of the first ring 301. The pressure nozzles 302 pressurize the water and spray it out, the water flow impacting the outside of the cylindrical measuring probe 104, washing away the concrete adhering to the probe. Because multiple pressure nozzles 302 surround the outside of the cylindrical measuring probe 104, they can cover the probe surface in all directions, ensuring the flushing effect. After flushing is completed, the auxiliary assembly 4 is operated using the external control terminal to de-energize the electromagnetic arc plate 404. After power is cut off, the magnetism is lost. Under the elastic force of the spring 403, the electromagnetic arc plate 404 drives the wiping inner plate 405 away from the metal inner ring 402 until the wiping inner plate 405 comes into contact with the outer side of the cylindrical measuring probe 104. The wiping inner plate 405 wipes the residual sewage on the probe surface clean, ensuring the probe is clean and ready for the next measurement. After the measurement and cleaning are completed, the construction personnel can store the handle assembly 2. By rotating the extension handle 201, it can be rotated around the rotating connector 200. After adjusting it to a suitable position, the extension handle 201 can be fixed with the claw bolt 202 to reduce the space occupied by the tool and make it easy to carry and store.

[0036] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
