Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a mortar strength testing device. Background Technology

[0002] Mortar plays a crucial role in construction engineering, and its strength is a key indicator of mortar quality, directly affecting the safety and durability of building structures. Accurate strength testing is of great significance for ensuring building quality. Currently, common methods for testing mortar strength include compressive strength testing, flexural strength testing, bond strength testing, and needle penetration testing, with each method selected based on different engineering requirements and site conditions.

[0003] Among numerous testing methods, compressive strength testing is widely used due to its applicability to various mortar types. This method involves applying pressure to a mortar specimen using a press until it breaks, recording the maximum pressure the specimen can withstand, and then dividing this value by the specimen's cross-sectional area to obtain the compressive strength. However, existing mortar testing equipment lacks the function of directly measuring the cross-sectional area of ​​the specimen. Testing personnel must rely on specialized measuring tools to determine the area, which undoubtedly increases the testing steps and negatively impacts the efficiency of the entire testing process, making it difficult to meet the needs of rapid and efficient construction testing.

[0027] This patent relates to a mortar strength testing device, the structure of which is as follows: Figures 1 to 5 As shown, the device mainly consists of a vertical plate 1, a base 11, a horizontal frame 12, a pressure sensor 2, a testing platform 3, a guide rail pair 4, a right-angle ruler 5, a hydraulic cylinder 6, a pressure head 7, and a digital display 8. The vertical plate 1 serves as the main support for the entire device, with its bottom fixedly connected to the base 11 and its top connected to the horizontal frame 12. The pressure sensor 2 is mounted on top of the base 11, and the testing platform 3 is mounted on top of the pressure sensor 2. A guide rail pair 4 is located on the front of the testing platform 3, and a right-angle ruler 5 is positioned on the upper side of the testing platform 3. The right-angle ruler 5 is connected to the movable end of the guide rail pair 4 and can move laterally along the guide rail pair to facilitate the measurement of the cross-sectional area of ​​the test block. A hydraulic cylinder 6 is located above the horizontal frame 12, and its extension rod passes downwards through the horizontal frame 12 and connects to the pressure head 7. The digital display 8 is electrically connected to the pressure sensor 2 and is used to record and display the values ​​measured by the pressure sensor 2 in real time.

[0028] To improve equipment performance, a cleaning brush 9 is installed between the right-angle ruler 5 and the test platform 3. See details... Figure 2 and Figure 3 The upper end of the cleaning brush 9 is connected to the right angle ruler 5, and the lower end of the cleaning brush 9 contacts the test platform 3. When the cleaning brush 9 moves with the right angle ruler 5, it can clean the mortar debris on the platform. The cleaning brush 9 includes a base mounting part 91 and a brush body 92. The top of the base mounting part 91 has a slider structure 911, and the bottom has a receiving cavity 912. The top of the brush body 92 is detachably embedded in the receiving cavity 912. The mounting groove 51 at the bottom of the right angle ruler 5 matches the slider mechanism 911, and the base mounting part 91 is embedded therein, which facilitates the quick installation and removal of the cleaning brush 9.

[0029] refer to Figure 4 The pressure head 7 includes a base 71 and a contact body 72. The base 71 is a rectangular block that is threadedly connected to the telescopic rod of the hydraulic cylinder 6. The contact body 72 has a concave structure and is wrapped around the bottom of the base 71. The base 71 has vertical grooves 711 on both sides, and the contact body 72 has corresponding protrusions 721 on both sides. The two sides together form a threaded hole 73, and a locking screw 74 is installed in the threaded hole 73 to ensure that the base 71 and the contact body 72 are tightly connected, which is both stable and convenient for replacing the contact body 72 as needed.

[0030] refer to Figure 1The test platform 3 has a flat plate equipotential platform 31 on one side and a triangular inclined platform 32 on the other side. The upper ends of the equipotential platform 31 and the platform 32 are flush with the test platform 3. The equipotential platform 31 is convenient for placing the mortar test block to be tested, while the platform 32 is convenient for the debris to be discharged smoothly after the test block is broken, so as to avoid accumulation and interference with subsequent testing.

[0031] refer to Figure 5 The digital display 8 integrates the control module of the hydraulic cylinder 6. Magnetic suction parts 81 are respectively provided on its side and the side of the upright plate 1. The digital display 8 is connected to the upright plate 1 via magnetic suction, making installation and disassembly convenient and allowing operators to adjust its position according to their habits. Furthermore, the pressure head 7, testing platform 3, equalization platform 31, and unloading platform 32 are all made of stainless steel and have undergone mirror finishing. Stainless steel is corrosion-resistant, wear-resistant, and has high strength, while the mirror finish improves flatness and facilitates cleaning.

[0032] During the test, the mortar specimen is placed on the equalization platform 31. Before testing, the mortar specimen is transferred to the testing platform 3, and the length and width of the specimen are measured by moving the right-angle ruler 5 to calculate the cross-sectional area. Then, the hydraulic cylinder 6 and pressure head 7 are moved downwards by the digital display 8 to apply pressure to the specimen until it is crushed. At this time, the digital display 8 records and displays the pressure value measured by the pressure sensor 2 in real time. The compressive strength of the mortar is calculated based on the measured maximum pressure value and the cross-sectional area. After the test of this specimen is completed, the right-angle ruler 5 is moved while the cleaning brush 9 cleans the residual mortar debris on the platform, allowing the debris to slide off the drop platform 32, and then the next specimen is tested.

[0033] This equipment solves the problem that traditional mortar strength testing equipment cannot directly measure the cross-sectional area of ​​test blocks. By adding a right-angle ruler 5 and a cleaning brush 9, the testing process is simplified, and the measurement efficiency and accuracy are improved. It also facilitates the cleaning of debris on the test platform 3. Furthermore, the replaceable contact body 72, the convenient digital display 8 connection method, and the use of mirror-finish stainless steel enhance the equipment's versatility, durability, and ease of operation, enabling it to better adapt to different testing needs and complex field environments.
