[0028] The pressure block 27 is arranged at the bottom of the pressure block 1 5, and a groove 25 is arranged on the top of the pressure block 27. When the pressure block 27 is located at the bottom of the pressure block 1 5, the pressure block 1 5 drives the pressure block 27 to move downward, which is used to test the compressive strength of the concrete. When the pressure block 27 is located at the top of the placement plate 6, the concrete is located on the pressure block 27, which is used to test the bending strength of the concrete.

[0029] like Figure 2 and Figure 4 As shown, in this embodiment, a mounting plate 19 is provided in the groove 25, a mounting plate 20 is fixed to the side of the pressure block 5, the mounting plate 19 is mounted on the mounting plate 20 by bolts, and the pressure block 27 is mounted on the mounting plate 20 on the side of the pressure block 5 by the mounting plate 19 and bolts.

[0030] like Figure 1-Figure 4 As shown, in this embodiment, a receiving groove 8 is provided at the bottom of the groove 25, an inner cavity 13 and an inner cavity 15 are provided inside the pressure block 27, a flow channel 14 is provided on the side of the inner cavity 13, the flow channel 14 is communicated with the inner cavity 15, a piston 12 is slidably connected in the inner cavity 13, a round rod 11 is fixed on the top of the piston 12, the round rod 11 movably passes through the top of the inner wall of the inner cavity 13 and is fixed with a slider 9, the slider 9 is slidably connected to the inner wall of the receiving groove 8, a spring 10 is fixed between the bottom of the slider 9 and the receiving groove 8, and the inner wall of the inner cavity 15 is slidably connected to the inner wall of the inner cavity 15. The groove 25 is movably connected with a piston 16, and a receiving groove 18 is provided at the bottom of the groove 25. A round rod 17 is fixed to the top of the piston 16. The top of the round rod 17 movably passes through the top of the inner wall of the inner cavity 15 and is fixed to the bottom of the mounting plate 19. The inner cavity 13, the flow channel 14 and the inner cavity 15 are all filled with hydraulic oil. After the pressure block 7 is placed on the placement plate 6, the mounting plate 19 will be stored in the receiving groove 18, and the top of the slider 9 will be in the same plane with the bottom of the inner wall of the groove 25. In this way, after impurities are accumulated on the inner wall of the groove 25, it is convenient for subsequent cleaning.

[0031] like Figure 4 As shown, in this embodiment, a slope 21 is provided on the side of the groove 25. When the pressing block 27 supports the strip concrete block, a large pressure will be formed on the top of the side of the groove 25 after the middle of the strip concrete block is compressed.

[0036] Working principle: When the compressive strength of the concrete test block is tested, the concrete test block is placed on the placement plate 6, and the hydraulic rod 4 is started. The hydraulic rod 4 will drive the pressure block 1 5 to move downward, and the pressure block 1 5 will drive the pressure block 2 7 to move downward. The pressure block 2 7 will press on the top of the concrete test block to achieve the compressive strength test of the concrete test block;

[0037] When the strip concrete test block is subjected to bending strength test, the pressure block 2 7 is moved to the placement plate 6, the bolts on the side of the mounting plate 19 are removed, and the pressure block 15 moves upward. At this time, the spring 10 drives the slider 9 to move upward, and the slider 9 drives the round rod 11 to move upward. After the slider 9 moves upward, the top of the slider 9 and the bottom of the inner wall of the groove 25 are in the same plane, and the round rod 11 drives the piston 12 to move upward. After the piston 12 moves upward, the pressure in the inner cavity 13 at the bottom of the piston 12 decreases. At this time, the hydraulic oil flows from the inner cavity 15 through the flow channel 14 and enters the inner cavity 13. At this time, the piston 16 moves downward, and the piston 16 drives the round rod 17 and the mounting plate 19 to move downward. The mounting plate 19 is stored downward in the storage groove 18. Then, the strip concrete test block is placed on the pressure block 2 7. At this time, the bending strength test of the strip concrete test block is realized by moving the pressure block 5 downward.
