[0002] As the main material of construction projects, the quality of concrete is directly related to the overall safety, stability and durability of the building. Therefore, testing concrete is an indispensable part of construction projects. Through testing, quality problems of concrete can be effectively discovered and timely measures can be taken to deal with them, thereby ensuring the safety and stability of the building.

[0003] Among them, the compressive strength test is one of the most important mechanical properties of concrete and an important indicator for testing the quality of concrete. During the test, the influence of external factors needs to be reduced to ensure the accuracy of the test results. The flatness of the test sample is an important factor during the test, which will greatly affect the force results of the test sample. In addition to external testing, internal water permeability is also one of the quality testing methods. Therefore, in order to be able to simultaneously test the compressive strength and water permeability, a concrete quality testing equipment based on construction engineering is proposed.

[0006] Furthermore, a scraper block structure is provided on the frame, and the scraper block structure consists of a telescopic plate and a scraper block. The scraper block is connected to the telescopic plate, and a pull rope is also connected to the telescopic plate. One end of the pull rope is connected to the telescopic end of the telescopic plate, and the other end of the pull rope is connected to the upper cover body through two fixed pulley guides. The two fixed pulleys are located in the frame, and the scraper block is a cylindrical structure.

The pad also has a protrusion and a groove, and the protrusion and the groove match each other. The bottom pad has the protrusion, the bottom of the support column has the groove, the intermediate pad has a protrusion on the top and a groove on the bottom. There is only one bottom pad on each support column, and there are several intermediate pads, and the height of the intermediate pads is 1CM.

[0009] Furthermore, a slot is provided directly below the opening slot, the slot is located in the lower cavity and has openings distributed in the slot, and the openings extend to the bottom of the lower cavity so that the lower cavity is connected.

[0010] Furthermore, the length, width and height of the open groove are the same as those of the slot, the length and width of the pressing block are smaller than the opening groove and the height of the pressing block is larger than the opening groove, the height of the opening groove plus the height of the slot is larger than the height of the pressing block, and if the height of the water cavity of the opening groove is not taken into account, the height of the opening groove plus the height of the slot will be smaller than the height of the pressing block.

[0011] Furthermore, a water discharge hole is provided on the material tray, a water receiving cavity is provided on the workbench, the water discharge hole is communicated with the water receiving cavity, and the water discharge hole is located directly below the lower cavity.

[0013] When performing compression test: place the test sample on the material tray, and make the scraper block and the test sample fit together, and drive the connecting block and the test device to press down through the operation of the first motor;

[0014] Since the upper cover is connected to the pull rope, the pull rope will be pulled at the same time when the detection device is pressed down, and the pull rope is guided by the fixed pulley so that the pull rope pulls the telescopic plate to contract, so that the scraper block scrapes the surface of the detection sample;

[0016] When conducting water penetration testing: on the basis of the compression test, the second motor drives the detection block to press down.

At this time, the detection block continues to press down, which will cause the pressure block to break the water cavity and let the water in the water cavity flow out.

[0017] When the water in the water cavity flows out, the water flows to the surface of the test sample through the openings in the slots and penetrates. Since the compression test is working synchronously, the lower cavity tightly presses the test sample, so no water leakage will be found;

[0018] By checking whether there is water flowing into the water receiving cavity through the drain hole, the water seepage amount of the test sample can be determined;

[0019] It also includes the adjustment method of the support column. When testing, the flatter the workbench is, the more uniform the force on the test sample will be;

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0041] See also Figure 1-Figure 9 The present invention provides a technical solution of a concrete quality detection device based on a construction project and a method for using the same: the structure includes a workbench 1, a frame 2 is set up on the workbench 1, a support column 3 for support is set at the bottom of the workbench 1, and four support columns 3 are set. A first motor 4 is set above the frame 2, and a connecting block 5 is connected to the output shaft of the first motor 4 and a detection device 6 is connected through the connecting block 5. The detection device 6 consists of an upper cover body 7 and a lower cavity 8, and the upper cover body 7 and the lower cavity 8 are threadedly connected by a thread 9. A material tray 10 is set on the workbench 1, and the workbench 1 is long. The four support columns 3 are respectively located at the four corners of the bottom of the workbench 1. Each support column 3 is provided with a transmitting end 301 and a receiving end 302. The four support columns 3 are respectively A column, B column, C column, and D column. The transmitting end of the A column corresponds to the receiving end of the B column, the transmitting end of the B column corresponds to the receiving end of the C column, the transmitting end of the C column corresponds to the receiving end of the D column, and the transmitting end of the D column corresponds to the receiving end of the A column. The transmitting ends 301 and the receiving ends 302 of the four support columns 3 are parallel to each other and correspond to form a rectangular shape. By using the principle characteristics of the transmitting end and the receiving end, it can be effectively known whether the support column has high and low feet.

[0042] The frame 2 is also provided with a scraper block structure 201, which is composed of a telescopic plate 202 and a scraper block 203. The scraper block 203 is connected to the telescopic plate 202, and a pull rope 204 is also connected to the telescopic plate 202. One end of the pull rope 204 is connected to the telescopic end of the telescopic plate 202, and the other end of the pull rope 204 is guided and connected to the upper cover body 7 through two fixed pulleys 205. The two fixed pulleys 205 are located in the frame 2. The scraper block is a cylindrical structure. The scraper block structure is used to scrape off the dust particle structure on the surface of the test sample to reduce external factors that may affect the data during the test. The scraper block is cylindrical. Compared with the flat scraper, the cylindrical scraper can more effectively scrape off the impurities on the surface.

[0043] Each of the support columns 3 is also provided with a pad 303, and the pad 303 includes a bottom pad 304 and an intermediate pad 305. The pad 303 is also provided with a convex block 306 and a groove 307, and the convex block 306 matches the groove 307. The bottom pad 304 has the convex block 306, and the bottom of the support column 3 has the groove 307. The intermediate pad 305 has a convex block 306 on the top and a groove 307 on the bottom. There is only one bottom pad 304 on each of the support columns 3, and there are several intermediate pads 305, and the height of the intermediate pads 305 is 1CM. By adding or reducing the intermediate pads 305, the support column 3 can be fine-tuned, thereby ensuring that the transmitting end and the receiving end are kept as corresponding as possible, thereby greatly reducing the error caused by unevenness;

[0044] The detection device 6 includes a second motor 601, and a detection block 602 is connected to the output shaft of the second motor 601. An open groove 603 is provided at the bottom of the detection block 602. A water cavity 604 is provided in the open groove 603, and a pressure block 605 is connected to the water cavity 604. The water cavity 604 will rupture when subjected to force, so that water can flow out. A slot 606 is provided directly below the open groove 603, and the slot 606 is located in the lower cavity 8 and has openings 607 distributed therein. The openings 607 extend to the bottom of the lower cavity 8 so that the lower cavity 8 is connected. The length, width and height of the open groove 603 are the same as those of the slot 606, and the length and width of the pressure block 605 are smaller than the opening groove 603. And the height of the pressing block 605 is greater than the opening groove 603, and the height of the opening groove 603 plus the height of the slot 606 is greater than the height of the pressing block 605. Without counting the height of the water cavity 604, the height of the opening groove 603 plus the height of the slot 606 will be less than the height of the pressing block 605. The material tray 10 is provided with a water discharge hole 1001, and the workbench 1 is provided with a water receiving cavity 1002. The water discharge hole 1001 is connected with the water receiving cavity 1002, and the water discharge hole 1001 is located directly below the lower cavity 8. The water penetration test must be carried out during the pressure resistance test to ensure that water will not leak out, and the pressure resistance test and the water penetration test can be carried out at the same time.

[0045] For example:

[0046] Before the test, the flatness of the workbench 1 is adjusted first. First, the four support columns 3 and the transmitting ends and receiving ends on the four support columns 3 are used to determine whether the workbench 1 is in a flat state. When it is not flat, the support columns 3 are fine-tuned by appropriately adding or subtracting the intermediate pads 305, so as to keep the corresponding between the transmitting end and the receiving end.

[0047] When the compression test is performed: the test sample is placed on the material tray 10, and the scraper block 203 and the test sample are in a fitted state, and the first motor 4 is driven to press the connecting block 5 and the detection device 6 downward. Since the upper cover 7 is connected to the pull rope 204, the pull rope 204 will be pulled at the same time when the detection device 6 is pressed downward. The pull rope 204 is guided by the fixed pulley 205 so that the pull rope 204 will pull the telescopic plate 202 to contract, so that the scraper block 203 will scrape the surface of the test sample, and the detection device 6 continues to press downward until the lower cavity 8 presses the test sample and the applied force and the time of applying pressure are appropriately adjusted and matched according to the test standard, so as to achieve compression test;

[0048] When water penetration test is performed: on the basis of the compression test, the second motor 601 works to drive the test block 602 to press down. When the test block 602 is pressed down, the pressing block 605 will be pressed against the slot 606. At this time, the test block 602 continues to press down, which will cause the pressing block 605 to break the water cavity 604 so that the water in the water cavity 604 flows out. When the water in the water cavity 604 flows out, the water flows to the surface of the test sample through the opening 607 in the slot 606 and penetrates. Since the compression test is working synchronously, the lower cavity 8 tightly presses the test sample, so no water leakage is found;

[0049] When super-strong pressure is required, since the pressure block 605 will break through the water cavity 604, the height of the pressure block 605 will be less than the height of the opening groove 603 plus the groove 606. At this time, the pressure block 605 will be located between the opening groove 603 and the groove 606. At this time, the second motor 601 continues to work, which will cause the detection block 602 to apply a downward pressure to the lower cavity 8 from the inside. At this time, the test sample will be subjected to the combined pressure of the first motor 4 and the second motor 601 at the same time, thereby achieving super-standard pressure resistance testing.
