Description

Technical Field

[0001] This utility model relates to the field of building engineering quality testing technology, and in particular to a building engineering quality testing device. Background Technology

[0002] Construction quality testing equipment is used to monitor and evaluate the quality of construction projects in real time. It includes a variety of instruments, such as infrared thermal imagers, ultrasonic detectors, and intelligent rebound hammers. Among them, the intelligent rebound hammer evaluates the compressive strength of concrete by measuring the rebound value, providing key data for project quality. The intelligent rebound hammer's intelligent functions, such as digital display, data storage, and automatic report generation, greatly improve the testing efficiency and accuracy.

[0003] Current methods for testing the compressive strength of building wall concrete require workers to use a smart rebound hammer to perform multi-point tests on the concrete. However, prolonged testing can cause the impact bar on the smart rebound hammer to tilt against the wall, making it difficult for the hammer to make precise vertical contact with the concrete and thus affecting the accuracy of the compressive strength test results. Utility Model Content

[0004] Therefore, it is necessary to provide a building engineering quality testing device to address the problem of difficulty in making intelligent rebound hammers accurately and vertically impact concrete walls.

[0005] The device includes: an intelligent rebound hammer; and an anti-deviation mechanism. The anti-deviation mechanism includes a control disc slidably connected to the inner wall of the intelligent rebound hammer. The inner wall of the control disc is slidably connected to annularly distributed anti-blocking blocks. A first rubber spring is fixedly connected to the opposite end of the anti-blocking blocks and the control disc, and a second rubber spring is fixedly connected to the opposite end of the control disc and the intelligent rebound hammer. Through the cooperation of the anti-blocking blocks, the control disc, and the first rubber spring, precise guidance is achieved when the intelligent rebound hammer contacts the building wall, preventing tilting of the impact rod on the intelligent rebound hammer. This ensures that the intelligent rebound hammer accurately and vertically contacts the building wall, thereby guaranteeing the accuracy of the concrete compressive strength test. The second rubber spring is used for automatic reset of the control disc, ensuring the convenience of using the intelligent rebound hammer.

[0006] In one embodiment, the surface of the intelligent rebound device is fixedly connected to two fixing blocks, and the inner wall of the fixing blocks is hinged with a handle.

[0007] In one embodiment, a friction sleeve is fixedly connected to the surface of the grip, with both ends of the friction sleeve curved into an arc shape. The friction sleeve improves the user's comfort and friction when gripping the grip, preventing slippage when pushing the intelligent rebound device.

[0008] In one embodiment, an anti-rotation rod is slidably connected to the inner wall of the grip, and the surface of the anti-rotation rod is engaged with the inner wall of the fixing block.

[0009] In one embodiment, a weight is fixedly connected to the top of the anti-rotation bar. The anti-rotation bar and the weight cooperate to lock the grip, ensuring stability of the grip after angle adjustment within the fixed block.

[0010] In one embodiment, two intercepting rods are fixedly connected to the top of the fixing block, and the surface of the grip is in contact with the surface of one of the intercepting rods. The intercepting rods precisely limit the rotation of the grip, ensuring that the anti-rotation rod is accurately locked within the fixing block, and the operation of positioning the grip within the fixing block is simple.

[0011] In one embodiment, a return spring is fixedly connected to the end of the anti-rotation rod, and the top end of the return spring is fixedly connected to the inner top wall of the grip.

[0012] In one embodiment, both the anti-slip block and the friction sleeve are rubber components.

[0013] Beneficial effects 1. By cooperating with the anti-slip block, the control plate, and the first rubber spring, the intelligent rebound hammer is precisely guided against the building wall, preventing the impact rod on the intelligent rebound hammer from tilting against the building wall. This ensures that the intelligent rebound hammer accurately and vertically contacts the building wall, thereby ensuring the accuracy of the concrete compressive strength test of the building wall. The second rubber spring is used to automatically reset the control plate, ensuring the convenience of using the intelligent rebound hammer. 2. By using the fixed block and the handle in coordination, the intelligent rebound hammer is pushed more effortlessly and conveniently, reducing the probability of the intelligent rebound hammer tilting when it hits the wall, and ensuring that the intelligent rebound hammer hits the building wall vertically, thereby ensuring the accuracy of the test of the compressive strength of the concrete of the building wall.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined with Figures 1-5 This utility model describes a construction engineering quality testing device.

[0019] In one embodiment, a construction engineering quality testing device includes: an intelligent rebound hammer 100; and an anti-deviation mechanism 200. The anti-deviation mechanism 200 includes a control disk 201 slidably connected to the inner wall of the intelligent rebound hammer 100. The inner wall of the control disk 201 is slidably connected to annularly distributed anti-blocking blocks 203. A first rubber spring 204 is fixedly connected to the opposite end of the anti-blocking blocks 203 and the control disk 201. A second rubber spring 202 is fixedly connected to the opposite end of the control disk 201 and the intelligent rebound hammer 100.

[0020] It should be noted that the HT-225W model can be selected for the Intelligent Rebound Tester 100.

[0021] In this embodiment, when performing compressive strength testing on the concrete of a building wall, a calibration test must be conducted on a steel anvil before the test. A fully charged intelligent rebound hammer 100 is struck vertically downwards onto the steel anvil, causing multiple anti-slip blocks 203 to contact the anvil. This ensures that one end of the rebound rod on the intelligent rebound hammer 100 precisely and vertically contacts the steel anvil, allowing the intelligent rebound hammer 100 to reach a suitable calibration value range. If the calibration value is not within this range, the intelligent rebound hammer 100 should be adjusted or calibrated to ensure the instrument is in normal working condition.

[0022] Using a special measuring stamp, press it against the concrete wall to be tested, and then set up multiple testing areas. At this time, the tester holds the intelligent rebound hammer 100 and moves it towards the testing area on the wall, so that multiple anti-slip blocks 203 first contact the testing area on the wall. Continue to push the intelligent rebound hammer 100, so that the anti-slip blocks 203 move within the control panel 201 and stretch the first rubber spring 204. When the anti-slip blocks 203 move to the appropriate position, the intelligent rebound hammer 100 continues to move towards the testing area on the wall, so that the control panel 201 moves within the intelligent rebound hammer 100 and stretches the second rubber spring 202. Then, the impact rod of the intelligent rebound hammer 100 is vertically aligned with the measuring point on the testing area, and pressure is slowly applied. After the impact hammer is released, the digital control screen on the intelligent rebound hammer 100 displays a certain value, which is the rebound value.

[0023] When the intelligent rebound device 100 moves away from the wall, the elastic force of the first rubber spring 204 pushes the anti-slip block 203 to reset, and the elastic force of the second rubber spring 202 pushes the control plate 201 to reset. The multiple anti-slip blocks 203 cooperate with the first rubber spring 204 to make one end of the control plate 201 horizontal with the building wall, thereby making the rebound rod on the intelligent rebound device 100 vertically abut against the wall.

[0024] The rebound value of each test point is measured sequentially in the above manner, and the rebound value of each test point is accurately read and recorded. The average value of the subsequent rebound values ​​is calculated, and the compressive strength value of the concrete in the wall test area is estimated.

[0025] like Figure 5 As shown, the surface of the intelligent rebound device 100 is fixedly connected to two fixed blocks 205. The inner wall of the fixed block 205 is hinged to a grip 206. The surface of the grip 206 is fixedly connected to a friction soft sleeve 207. Both ends of the friction soft sleeve 207 are curved into an arc shape. The inner wall of the grip 206 is slidably connected to an anti-rotation rod 208. The surface of the anti-rotation rod 208 is snapped into the inner wall of the fixed block 205. The top of the anti-rotation rod 208 is fixedly connected to a weight block 211. The top of the fixed block 205 is fixedly connected to two intercepting rods 210. The surface of the grip 206 contacts the surface of one of the intercepting rods 210. The end of the anti-rotation rod 208 is fixedly connected to a return spring 209. The top of the return spring 209 is fixedly connected to the inner top wall of the grip 206. The anti-slip block 203 and the friction soft sleeve 207 are both rubber components.

[0026] In this embodiment, initially, the grip 206 and the smart rebound device 100 are parallel. When the smart rebound device 100 needs to be used, the weight block 211 is pulled upward, causing the anti-rotation rod 208 to move upward within the grip 206, squeezing the return spring 209 and moving it away from the fixed block 205. This pushes the friction sleeve 207, causing the grip 206 to rotate 90 degrees within the fixed block 205 and contact the surface of the corresponding interceptor 210. At this time, the elastic force of the return spring 209 pushes the anti-rotation rod 208 and the weight block 211 downward, causing the anti-rotation rod 208 to be stuck within the fixed block 205, locking the grip 206 onto the fixed block 205. This makes the grip 206 and the smart rebound device 100 perpendicular. The other grip 206 is then adjusted in the same way. At this time, the hand grips the friction sleeve 207, thus effortlessly pushing the smart rebound device 100 towards the wall.

[0027] Working principle: The testing personnel hold the friction sleeve 207 and move the intelligent rebound hammer 100 towards the test area on the wall, so that multiple anti-slip blocks 203 first contact the test area on the wall. Continue to push the intelligent rebound hammer 100, so that the anti-slip blocks 203 move within the control panel 201 and stretch the first rubber spring 204. When the anti-slip blocks 203 move to the appropriate position, the intelligent rebound hammer 100 continues to move towards the test area on the wall, so that the control panel 201 moves within the intelligent rebound hammer 100 and stretches the second rubber spring 202. Then, the impact rod of the intelligent rebound hammer 100 is vertically aligned with the test point on the test area, and pressure is slowly applied. After the impact hammer is released, the digital control screen on the intelligent rebound hammer 100 displays a certain value, which is the rebound value.

[0028] It should be noted that the intelligent rebounder 100, the second rubber spring 202, the first rubber spring 204, the reset spring 209, and the weight block 211 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the intelligent rebounder 100 can be powered by the built-in power supply or by the mains power. The specific power supply method can be selected according to the situation, and will not be elaborated here.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended 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.
