[0002] Concrete core measuring equipment is a device used to measure concrete core samples (also called concrete drill cores) to evaluate the quality and strength of concrete structures. Concrete core samples are taken from existing concrete structures, usually by drilling core samples. These samples are then subjected to various physical and chemical tests in the laboratory. Concrete core measuring equipment may include a variety of instruments and tools, such as: Dimension measuring tools: used to measure the diameter, length and shape of the core sample to ensure that the sample meets the test standards. Density measuring instruments: used to determine the density of concrete, which is related to its quality and durability. Strength testing machines: such as pressure testing machines, are used to apply pressure to the core sample until it breaks to determine its compressive strength. Moisture measuring instruments: used to measure the moisture content of concrete samples. Porosity and permeability testing equipment: evaluates the pore structure of concrete and its ability to resist the penetration of water and other fluids. These test results help engineers evaluate the integrity of concrete structures and check whether the design standards and construction quality requirements are met.

[0020] See also Figure 1-3 , the utility model provides the following technical solutions: please refer to Figure 1-3 The utility model provides the following technical solutions: a construction engineering concrete core sample measuring device, comprising a bottom plate 1, a support bracket 3 and a collection box 5 are fixedly connected to the lower surface of the bottom plate 1, a motor 2 is fixedly connected to the inside of the support bracket 3, a threaded column 8 is fixedly connected to the output shaft of the motor 2, a threaded tube 9 is threadedly connected to the surface of the threaded column 8, a movable plate 10 is fixedly connected to the surface of the threaded tube 9, a sliding rod 12 is slidably connected to the inside of the movable plate 10, a baffle 11 is fixedly connected to the upper end of the sliding rod 12 and the threaded column 8, the lower end of the sliding rod 12 is fixedly connected to the upper surface of the bottom plate 1, a transmission rod 13 is fixedly connected to the lower surface of the transmission rod 13, a pressure plate 14 is fixedly intercepted at the lower end of the transmission rod 13, a slider 16 is fixedly connected to the surface of the pressure plate 14, and the slider 1 The surface of 6 is slidably connected with a protective frame 15. By setting a slider 16 and the protective frame 15, in actual applications, through the cooperation between the above, the concrete placed on the surface of the base plate 1 can be fully protected, avoiding environmental pollution caused by splashing of concrete debris under the continuous pressure of the pressure plate 14, ensuring the personal safety of the operator. At the same time, since the protective frame 15 is made of transparent material, it does not affect the data observation of the operator. The interior of the base plate 1 is provided with a mesh 7, and the interior of the collection box 5 is slidably connected with a drawer 6. By setting the mesh 7, the collection box 5 and the drawer 6, in actual applications, through the cooperation between the above, the concrete debris generated under the continuous pressure can be collected, thereby reducing the time required for later cleaning and improving the cleaning efficiency.
[0021] Specifically, the lower surface of the base plate 1 is fixedly connected with support legs 4 , and the number of the support legs 4 is four and they are distributed in a rectangular shape at the four corners of the lower surface of the base plate 1 .
[0022] Specifically, a handle 18 is fixedly connected to the surface of the drawer 6 , and the position of the mesh 7 corresponds to the position of the drawer 6 .
[0023] Specifically, the shape of the protection frame 15 is a transparent rectangular parallelepiped, the inner length and width of the protection frame 15 are the same as the length and width of the pressing plate 14, and the protection frame 15 is made of a transparent material.
[0024] Specifically, a slide groove 17 is provided inside the protection frame 15 , and the protection frame 15 is slidably connected to the slider 16 via the slide groove 17 .
[0025] The working principle of the utility model is:
[0026] When the device is in use, first place the sampled concrete block just above the mesh hole 7 opened on the bottom plate 1, then turn on the motor 2 through the external controller, so that the motor 2 drives the threaded column 8 to rotate inside the threaded tube 9. At the same time, since the movable plate 10 is fixedly connected to the threaded tube 9 and the slide bar 12 positions the movable plate 10, the threaded tube 9 will drive the movable plate 10 to move up and down with the rotation of the threaded column 8. In the process of continuous descent, the protection frame 15 will first contact the bottom plate 1 to fully protect the concrete on the bottom plate 1. The pressing plate 14 will slide inside the protection frame 15 under the action of the slider 16 as it continues to descend. The continuous descent exerts pressure on the concrete, and the protective frame 15 blocks the debris generated in the process to avoid environmental pollution and possible personal injury caused by flying debris. At the same time, the debris generated in the process of continuous pressure exerted by the pressing plate 14 will pass through the mesh 7 and enter the interior of the drawer 6 for collection until the detection work is completed and the motor 2 is stopped. During the detection process, since the protective frame 15 is made of transparent material, it does not affect the operator's data recording during the detection process. Then, the motor 2 is controlled to rotate in the opposite direction to drive the protective frame 15 and the pressing plate 14 to rise, so that the broken concrete blocks can be collected, and the debris can be further processed by pulling out the drawer 6 through the handle 18.
