[0023] To achieve mortar strength testing, it is usually necessary to follow the following steps: 1. Prepare mortar samples that meet the requirements according to actual needs. It is usually necessary to prepare mortar according to the proportion requirements in the standard specifications, and fill it into the mold for vibration and curing; 2. Take out the test specimen that meets the requirements of the specification from the prepared mortar sample, which is usually a rectangular or cylindrical sample; 3. Prepare the mortar strength testing device, including the pressure loading system, testing instruments and control system; 4. Start the pressure loading system to apply gradually increasing pressure to the mortar sample to simulate the stress condition. During the loading process, monitor and record the pressure data of the sample; 5. Evaluate whether the strength of the mortar sample meets the design requirements based on the test results, and make necessary records and analyses. The detection and evaluation of mortar strength can provide an important reference for the quality control and safety assurance of construction projects. However, mortar stone samples are easily squeezed and broken during testing, resulting in splashing stones, which poses a safety hazard.

[0024] Embodiment 1:

[0025] Based on the technical defects of the existing technology that the mortar stone samples are easy to break during testing, which may cause safety hazards, please refer to Figure 1-Figure 4 The utility model provides a building mortar strength testing device. During the testing process, two protective covers 56 are closed to protect the mortar stone sample inside. In this way, when the mortar stone sample is squeezed and crushed subsequently, the stone will also be blocked inside the protective cover 56, and will not cause safety hazards to external personnel. The device includes a body 1, a base 2 is fixedly provided on the body 1, and a hydraulic cylinder 3 installed on one side of the body 1 is provided directly above the base 2. A pressure plate 4 is installed on the telescopic shaft of the hydraulic cylinder 3, and a protective mechanism 5 for preventing fragments from splashing is connected to the telescopic shaft of the hydraulic cylinder 3. The protective mechanism 5 can cover the mortar stone sample inside to avoid the problem of safety hazards caused by the crushing of the mortar stone sample. A cleaning mechanism 6 for cleaning fragments is also fixedly provided at a position near the base 2 on the inner side of the body 1; the cleaning mechanism 6 can push the stone on the base 2 into the collection box 9 to avoid affecting the next test work.

[0026] In order to prevent the mortar stone sample from being squeezed and crushed during the test and the stones from splashing out, a protective mechanism 5 is set to block the stones inside, and the protective mechanism 5 includes a moving component connected to the telescopic shaft of the hydraulic cylinder 3, and two symmetrically arranged protective covers 56 are fixed on the moving component. The opposite surfaces of the two protective covers 56 are open, and the top surface is provided with a semicircular through hole for the pressure plate 4 to enter and exit; the mortar stone sample is covered by the protective cover 56, and even if the mortar stone sample is broken, the stones will be blocked inside and will not splash out.

[0027] Specifically, in order to facilitate the control of the movement of the two protective covers 56 and to form a linkage effect with the movement of the hydraulic cylinder 3, that is, when the hydraulic cylinder 3 moves downward, the protective cover 56 is closed, and when the hydraulic cylinder 3 moves upward, the protective cover 56 is opened. Therefore, a moving component is set, and the moving component includes a connecting block 51 connected to the telescopic shaft of the hydraulic cylinder 3, one end of the connecting block 51 is fixedly provided with a driving plate 52, both ends of the driving plate 52 are provided with driving holes, and a cylindrical slider 53 is slidably arranged in the driving hole, the slider 53 is fixedly connected to the side wall of the sliding sleeve 54, the sliding sleeve 54 is sleeved on the fixing frame 55, the fixing frame 55 is fixedly connected to the inner side of the body 1, and the sliding sleeve 54 is fixedly connected to the side wall of the protective cover 56; the connecting block 51 is connected to the telescopic shaft of the hydraulic cylinder 3, so that when the hydraulic cylinder 3 moves, the driving plate 52 will also be driven to move through the connecting block 51, and the driving plate 52 forces the slider 53 to move under the action of the driving hole, and the slider 53 drives the protective cover 56 to move through the sliding sleeve 54, so that the two have a linkage effect.

[0028] Furthermore, in order to facilitate viewing of the status of the mortar stone sample during the test, the protective cover 56 is made of a transparent plastic material, so that the mortar stone sample can be directly seen through the protective cover 56 .

[0029] Furthermore, in order to facilitate the control of the opening and closing of the protective cover 56, the driving plate 52 is set to a "U" shape, and the two ends are bent outward. When the driving plate 52 moves downward, the driving hole can squeeze the two sliders 53 closer to each other, so that the two protective covers 56 are closed. The uppermost part of the driving hole is vertical. During the subsequent extrusion test, the two protective covers 56 will not continue to move, thereby avoiding motion interference. On the contrary, when the driving plate 52 moves upward, the two protective covers 56 can be automatically opened, which is convenient for taking and placing mortar stone samples.

[0030] According to the embodiment, during the test, the mortar stone sample is first placed on the base 2, and the mortar stone sample should be directly below the pressure plate 4, then the hydraulic cylinder 3 is started and the pressure plate 4 is driven to move downward, and the connecting block 51 is used to connect the telescopic shaft of the hydraulic cylinder 3, so that when the hydraulic cylinder 3 moves, it will also drive the drive plate 52 to move through the connecting block 51, and the drive plate 52 forces the slider 53 to move under the action of the driving hole, and the slider 53 drives the protective cover 56 to move through the sliding sleeve 54. When the two protective covers 56 are closed, the pressure plate 4 enters the interior through the through hole on the protective cover 56, and then the pressure plate 4 contacts the mortar stone sample and performs the pressure test. After the test is completed, the hydraulic cylinder 3 is reset and the two protective covers 56 are opened, and the mortar stone sample after the test can be removed.

[0031] Embodiment 2:

[0032] After the mortar stone sample is tested, some broken stones will be left on the base 2.

[0036] Through the above embodiments, it can be known that the use process of the device is as follows: during the test, the mortar stone sample is first placed on the base 2, and the mortar stone sample must be directly below the pressure plate 4, and then the hydraulic cylinder 3 is started to drive the pressure plate 4 to move downward, and the connecting block 51 is connected to the telescopic shaft of the hydraulic cylinder 3, so that when the hydraulic cylinder 3 moves, it will also drive the driving plate 52 to move through the connecting block 51, and the driving plate 52 forces the slider 53 to move under the action of the driving hole, and the slider 53 drives the protective cover 56 to move through the sliding sleeve 54. When the two protective covers 56 are closed, , the pressure plate 4 enters the interior through the through hole on the protective cover 56, and then the pressure plate 4 contacts the mortar stone sample and performs pressure testing. After the test is completed, the hydraulic cylinder 3 is reset and the two protective covers 56 are opened, and the mortar stone sample after the test is removed.
