[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figure 1 - Figure 5As shown, this utility model provides a concrete compressive strength testing device for building engineering, including a support frame 1. A testing mechanism 5 is installed at the top of the support frame 1. A testing box 3 is fixedly connected to one side of the support frame 1. An adjustment mechanism 2 is installed on one side of the testing box 3. A cleaning mechanism 4 is installed on the other side of the testing box 3. The cleaning mechanism 4 includes a second motor 41. One side of the second motor 41 is fixedly connected to one side of the testing box 3. A threaded rod 410 is fixedly connected to the output end of the second motor 41 through the testing box 3. A cleaning plate 411 is threadedly connected to the external thread of the threaded rod 410. A push block 42 is fixedly connected to one end of the cleaning plate 411. A fixing block 48 is fixedly connected to the inside of the detection box 3. A telescopic rod 47 is fixedly connected to one end of the fixing block 48. A spring 49 is sleeved on the outside of the telescopic rod 47. A baffle 45 is fixedly connected to one end of the telescopic rod 47. The spring 49 is located between the fixing block 48 and the baffle 45. A push groove 46 is opened on one side of the baffle 45. A first guide rod 43 is fixedly connected inside the detection box 3. The outside of the first guide rod 43 is slidably connected to the cleaning plate 411. An opening 44 is opened on the bottom side of the detection box 3.

[0026] After the pressure test is completed, the second motor 41 drives the threaded rod 410 to rotate, and the threaded cleaning plate 411 moves. The cleaning plate 411 slides outside the first guide rod 43, and the fixed cleaning plate 411 moves in a straight line. The movement of the cleaning plate 411 pushes the debris on the bottom side of the test box 3 to the other side. The pushing block 42 moves to contact the pushing groove 46. The pushing block 42 is set at an inclination, which can push the pushing groove 46 upward. The baffle 45 moves upward, the telescopic rod 47 retracts, the spring 49 is compressed, and the baffle 45 separates from the opening 44, so that the debris is pushed to the opening 44 and falls down, cleaning the debris inside the test box 3 and preventing the debris remaining inside the test box 3 from being pressed into the surface of the new test piece and changing the actual stress area of ​​the test piece.

[0027] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the adjustment mechanism 2 includes a gear 21 and a belt assembly 29. A shift rack 24 meshes with both sides of the gear 21. A moving bar 25 is fixedly connected to one end of the shift rack 24. An adjustment block 26 is fixedly connected to one side of the moving bar 25. A moving block 22 is fixedly connected to one side of the shift rack 24. A guide rail 23 is slidably connected to one side of the moving block 22. One side of the guide rail 23 is fixedly connected to one side of the detection box 3. A rotating rod 27 is fixedly connected to the middle of the gear 21. One end of the rotating rod 27 passes through one side of the detection box 3. One end of the rotating rod 27 is connected to a first motor 28 via the belt assembly 29. One side of the first motor 28 is fixedly connected to... The detection mechanism 5 includes a second electric push rod 56, one side of which is fixedly connected to the top of the support frame 1. A movable plate 52 is fixedly connected to one end of the second electric push rod 56. A third guide rod 55 is slidably connected to one side of the movable plate 52. The end of the third guide rod 55 is fixedly connected to the top of the support frame 1. A first electric push rod 54 is fixedly connected to the middle of the movable plate 52. One end of the first electric push rod 54 passes through the movable plate 52 and is fixedly connected to a pressure plate 51. A second guide rod 53 is fixedly connected to one side of the pressure plate 51. The outer side of the second guide rod 53 is slidably connected to the movable plate 52.

[0028] The concrete sample to be tested is placed inside the testing chamber 3. The belt assembly 29 consists of two pulleys and a conveyor belt. The first motor 28 drives the rotating rod 27 to rotate, and the gear 21 rotates accordingly. Through the meshing between the gear 21 and the shifting rack 24, the shifting rack 24 is driven to move. The moving block 22 slides outside the guide rail 23, and the fixed shifting rack 24 moves linearly. The movement of the two shifting racks 24 sequentially drives the moving bar 25 and the adjusting block 26 to move. Through the two adjusting blocks 26, the placed concrete sample is pushed towards the center, and the concrete... The concrete sample is positioned correctly to ensure uniform stress during the loading process, thereby accurately measuring the true compressive strength of the concrete. The first electric push rod 54 drives the pressure plate 51 to press down. During the pressing process, the second guide rod 53 slides on the moving plate 52, and the fixed pressure plate 51 moves in a straight line. The pressure plate 51 presses down to perform a pressure test on the concrete sample. The second electric push rod 56 can drive the moving plate 52 to move the pressure plate 51 above different test boxes 3 to perform compressive strength testing on the concrete sample inside the test box 3.

[0029] The method of use and working principle of this device: The concrete sample is placed inside the test chamber 3. The first motor 28 drives the rotating rod 27 to rotate, and the gear 21 rotates accordingly, driving the shifting rack 24 to move. The moving bar 25 and the adjusting block 26 move, pushing the placed concrete sample towards the center. When the first electric push rod 54 works, it drives the pressure plate 51 to press down, performing a pressure test on the concrete sample. The second electric push rod 56 can drive the moving plate 52 to move, moving the pressure plate 51 above different test chambers 3 to perform a compressive strength test on the concrete sample inside the test chamber 3. After the compressive strength test is completed, the second motor 41 drives the threaded rod 410 to rotate, and the cleaning plate 411 moves, pushing the debris on the bottom side of the test chamber 3 to the other side. The pushing block 42 moves to contact the pushing groove 46, pushing the pushing groove 46 upward. The baffle 45 separates from the opening 44, causing the debris to be pushed to the opening 44 and fall down.
