Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a concrete hardness detection device. Background Art

[0002] Concrete is an artificial stone made of cementitious materials, granular aggregate (also called aggregate), water, and admixtures and additives added in a certain proportion, which is evenly mixed, densely formed, and cured and hardened.

[0003] Concrete deforms under load or temperature and humidity, primarily through elastic deformation, plastic deformation, shrinkage, and temperature deformation. The elastic modulus is the primary indicator of concrete's elastic deformation under short-term loads. Under long-term loads, creep refers to a phenomenon in which stress remains constant but strain continues to increase, while relaxation refers to a phenomenon in which strain remains constant but stress continues to decrease. Volumetric deformation due to factors such as cement hydration, carbonation of cement paste, and water loss is called shrinkage. Deformation of hardened concrete stems from two factors: environmental factors (temperature and humidity changes) and applied loads.

[0004] After concrete is poured, its strength needs to be tested using a hardness testing device. Commonly used concrete hardness testing devices include concrete rebound testers. The measurement principle is to use a spring-driven hammer to impact the impact rod that is in vertical contact with the concrete surface, causing local deformation of the concrete to absorb part of the energy. The remaining energy is converted into the rebound kinetic energy of the hammer. When this part of the kinetic energy is completely converted into potential energy, the hammer rebounds to the maximum distance, and this distance is finally displayed on the scale or digital display as the rebound value.

[0005] The patent document with publication number CN220322918U discloses a concrete hardness detection device. The anti-slip sleeve and the end cover sleeve are elastically deformable, and the outer surfaces of the end cover sleeve and the outer surfaces of the anti-slip sleeve are provided with anti-slip grooves, which can increase the friction coefficient and improve the anti-slip effect.

[0006] However, in the process of implementing the above technical solution, it was found that the above technical solution had the following technical problems:

[0007] The concrete rebound test hammer in the existing concrete hardness testing device increases the friction coefficient by utilizing the anti-slip grooves on the outer surface of the end cover and the anti-slip sleeve to ensure the test stability. However, in actual application, since the contact area between the detection head of the device and the concrete is relatively narrow, even if the control effect of the device can be improved, it is still difficult to ensure that the axis of the device is always perpendicular to the concrete test surface, and the detection accuracy is easily affected. Utility Model Content

[0008] In order to overcome the shortcomings of the concrete rebound tester of the existing concrete hardness testing device, such as the narrow contact area between the testing head of the device and the concrete, even if the control effect of the device can be improved, it is still difficult to ensure that the axis of the device is always perpendicular to the concrete test surface, and the detection accuracy is easily affected, the embodiment of the present application provides a concrete hardness testing device, which fixes the correction structure to the monitoring device body by utilizing two clamping arc plates to be buckled on the outside of the testing body. When the user passes the fingers of one hand through the finger groove on the control base and holds the monitoring device body, and the other hand supports the bottom of the supporting arc plate, the surface of the support ring and the surface of one end of the testing head can be supported on the concrete surface, so as to ensure that one end of the monitoring device body is perpendicular to the concrete surface, so as to achieve the effect of accurate testing.

[0009] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0010] A concrete hardness detection device comprises a monitoring device body and a correction structure, wherein the correction structure is sleeved on the outside of the monitoring device body;

[0011] The monitoring device body includes a detection body, one end of the detection body is externally connected to a control shell, and the other end of the detection body is internally provided with a detection head;

[0012] The correction structure includes a correction base plate, one end and a middle portion of the correction base plate are integrally formed with a clamping arc plate, and the other end of the correction base plate is integrally formed with a support ring.

[0013] In one possible implementation, the two clamping arc plates are respectively buckled onto the outside of one end and the outside of the center of the detection body, the control shell is located between the two clamping arc plates, one end of the detection head passes through the inside of the support ring, and the end face is flush with one side surface of the support ring.

[0014] In a possible implementation, a control frame is machined on the outer wall of one end of the correction base plate, and four finger grooves are machined inside the control frame. The control frame is located at the bottom of the control shell, and fingers pass through the four finger grooves.

[0015] In a possible implementation, a supporting arc plate is integrally formed on the outside of one end of the correction base plate, and the supporting arc plate is located between a clamping arc plate and a support ring.

[0016] In a possible implementation, two assembly sleeves are integrally formed on one side of the support ring, and bubble levels are assembled and connected to the interiors of the two assembly sleeves.

[0017] In a possible implementation, observation windows are machined inside the two assembly sleeves, and the bubbles in the bubble level are exposed inside the observation windows.

[0018] In a possible implementation, the detection head and the support ring are coaxially arranged, the two assembly sleeves are symmetrically arranged on both sides of the support ring, and the centers of the detection head and the two assembly sleeves are located on the same straight line.

[0019] In summary, the present invention has at least one of the following beneficial technical effects:

[0020] 1. By using two clamping arc plates to buckle onto the outside of the detection body, the correction structure is fixed to the monitoring device body. When the user passes the fingers of one hand through the finger groove on the control base and holds the monitoring device body, and the other hand supports the bottom of the support arc plate, the surface of the support ring and the surface of one end of the detection head can be supported on the concrete surface, which is convenient for ensuring that one end of the monitoring device body is perpendicular to the concrete surface, so as to achieve the effect of accurate testing;

[0021] 2. By processing two assembly sleeves with bubble levels inside on one side of the support ring, when the correction structure is fixed to the outside of the monitoring device body and the monitoring device body is kept in a horizontal state, the position of the bubble inside the bubble level can be observed to determine whether the axis of the correction structure is parallel to the axis of the monitoring device body, thereby ensuring the effect of the correction structure assisting the monitoring device body in detection.

[0026] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0027] Example 1:

[0028] This embodiment introduces a specific structure of a concrete hardness detection device. Figure 1-Figure 3As shown, it includes a monitoring device body 1 and a correction structure 2 sleeved on the outside of the monitoring device body 1. The monitoring device body 1 includes a detection body 102. The control shell 101 is assembled and connected to the outside of one end of the detection body 102. The detection head 103 is provided inside the other end of the detection body 102.

[0029] like Figure 1 As shown, the correction structure 2 includes a correction base plate 206, one end and the middle of the correction base plate 206 are integrally formed with a clamping arc plate 202, and the other end of the correction base plate 206 is integrally formed with a support ring 205;

[0030] The two clamping arc plates 202 are respectively fastened to the outside of one end and the outside of the center of the detection body 102, so that the control housing 101 is located between the two clamping arc plates 202 (the control housing 101 is used to restrict the two clamping arc plates 202 from sliding along the axis of the detection body 102 on the outside of the detection body 102), thereby facilitating the assembly and fixation of the correction structure 2 and the monitoring device body 1;

[0031] At the same time, by passing one end of the detection head 103 through the interior of the support ring 205, and with the end face flush with one side surface of the support ring 205, when the monitoring device body 1 is used to perform concrete testing, the surface of the support ring 205 is in contact with the concrete surface, and the surface of one end of the detection head 103 is in contact with the concrete surface, thereby ensuring the basic prerequisite that the monitoring device body 1 can test concrete (hereinafter related descriptions are all concrete products, typically concrete stone) through the detection head 103, and the test is performed based on the working principle of the existing concrete hardness testing device (i.e., concrete rebound test hammer);

[0032] Secondly, in order to facilitate the user to control the correction structure 2, one end of the monitoring device body 1 is perpendicular to the wall to perform the hardness test. Figure 1 and Figure 3 As shown, the outer wall of one end of the correction base plate 206 is processed with a control base frame 203, and the interior of the control base frame 203 is processed with four finger grooves 3. By placing the control base frame 203 at the bottom of the control housing 101, when the fingers pass through the four finger grooves 3, it is convenient for the user to control one end of the monitoring device body 1 through the correction structure 2, thereby controlling the support ring 205 on the correction structure 2 and one end of the detection head 103 on the monitoring device body 1 to fit with the concrete surface;

[0033] Furthermore, in order to facilitate the user to stably control the monitoring device body 1 through the correction structure 2 to test the target concrete, Figure 1As shown, a support arc plate 201 is integrally formed on the outside of one end of the correction base plate 206. The support arc plate 201 is located between a clamping arc plate 202 and a support ring 205. When the user uses the control base 203 to hold the monitoring device body 1 with one hand, the other hand is placed on the bottom of the support arc plate 201, and the monitoring device body 1 is controlled by both hands to perform the test of the concrete surface hardness.

[0034] By adopting the above technical solutions:

[0035] The above design utilizes two clamping arc plates 202 to buckle onto the outside of the detection body 102, and positions the two clamping arc plates 202 between the two ends of the control shell 101 to fix the correction structure 2 to the monitoring device body 1. When testing the target concrete hardness, the user passes the fingers of one hand through the finger groove 3 on the control base frame 203, and supports the bottom of the supporting arc plate 201 with the other hand. The user can hold and lift the surface of the support ring 205 and the surface of one end of the detection head 103 on the concrete surface, thereby ensuring that one end of the monitoring device body 1 is perpendicular to the concrete surface and accurately testing the concrete hardness.

[0036] Example 2:

[0037] Based on Example 1, this example introduces the specific structure of the correction base plate 206. Figure 1 and 3 As shown, one side of the support ring 205 is integrally formed with two assembly sleeves 204, the interiors of the two assembly sleeves 204 are assembled and connected with bubble levels 4, and the interiors of the two assembly sleeves 204 are processed with observation windows 5;

[0038] The two assembly sleeves 204 are equipped with a bubble level 4. The bubble inside the bubble level 4 is located at the center (based on the bubble inside the bubble level 4 being exposed inside the observation window 5). This is used to observe whether the concrete surface remains perpendicular to the ground when the support ring 205 is attached to the concrete surface (the monitoring device body 1 and the correction structure 2 are both in a horizontal state for testing).

[0039] Secondly, in order to enable the two bubble levels 4 to monitor the assembly status of the correction structure 2 and the monitoring device body 1, it is ensured that the correction structure 2 can be used to support the monitoring device body 1 to maintain verticality with the concrete surface, such as Figure 1 and 3As shown, the detection head 103 and the support ring 205 are coaxially arranged, and the two mounting sleeves 204 are symmetrically arranged on both sides of the support ring 205. By making the centers of the detection head 103 and the two mounting sleeves 204 be located on the same straight line, it is possible to use the monitoring device body 1 to maintain a horizontal state to determine whether the bubble level 4 inside the mounting sleeve 204 on the correction structure 2 is in a horizontal state (the position of the bubble inside the bubble level 4).

[0040] By adopting the above technical solutions:

[0041] The above design processes two assembly sleeves 204 on one side of the support ring 205 and assembles the bubble level 4 inside the two assembly sleeves 204. When the correction structure 2 is fixed to the outside of the monitoring device body 1 and the monitoring device body 1 is kept in a horizontal state, it is possible to observe from the inside of the observation window 5 whether the bubble level 4 is in a horizontal state (the position of the bubble inside the bubble level 4), thereby ensuring the effect of the correction structure 2 assisting the monitoring device body 1 in detection.

[0042] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
