[0002] Concrete, as one of the most important materials in construction engineering, directly affects the safety and durability of structures through its mechanical properties. In the evaluation of concrete's mechanical properties, compressive strength and tensile strength are two key indicators. Compressive strength reflects the concrete's ability to withstand pressure, while tensile strength reflects its ability to resist tensile failure.

[0003] However, traditional testing methods require the use of two separate sets of equipment. This separate testing approach has the following problems: First, using two sets of equipment increases testing costs and occupies more laboratory space; second, testing efficiency is low, and operators need to switch between different devices, which increases testing time and management complexity.

[0019] The present invention discloses the following technical effects:

[0020] In this device, the force-applying mechanism is used to apply external force to the concrete material to be tested during compressive strength testing and tensile strength testing.

Then the second base plate stops moving. The force application mechanism applies force to the first base plate. The first base plate applies a pushing force to the fixed column. When the fixed column moves, the connecting column will move in the first through hole, so that the first slider moves away from the second pressure sensor and comes into contact with the side wall of the cavity, so that the force can be transmitted to the concrete material to be tested. The pressure on the concrete material to be tested can be measured by the first pressure sensor.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1-4 This invention provides a concrete material strength testing device, comprising:

[0033] A base 1 is fixedly connected to an outer frame, which includes an upper plate 2 and a lower plate 3. The upper plate 2 and the lower plate 3 are fixedly connected by a reinforcing plate 4.

[0034] The measuring assembly includes a force application mechanism, a tension clamping mechanism, and a data acquisition mechanism. The force application mechanism is mounted on an upper plate 2 and a lower plate 3, and is driven by a first base plate 5 located between the upper plate 2 and the lower plate 3. A fixing post 6 is fixedly connected to the first base plate 5, and a cavity 7 is formed in the fixing post 6. A first slider 8 is slidably mounted in the cavity 7, and a first through hole is formed in the cavity 7. A connecting post 9 is fixedly connected to the first slider 8, and the connecting post 9 extends out of the cavity 7 through the first through hole. A conical force-bearing block 10 is detachably connected to the connecting column 9. A tension clamping mechanism is installed on the conical force-bearing block 10. During tensile testing, the tension clamping mechanism is used to clamp the concrete material 13 to be tested. A pressure sensor 11 is fixedly connected to the conical force-bearing block 10, and a pressure sensor 12 is fixedly connected inside the cavity 7. During compressive testing, pressure sensor 11 is used to measure the compressive strength of the concrete material 13 to be tested, and during tensile testing, pressure sensor 12 is used to measure the tensile strength of the concrete material 13 to be tested.

[0035] A fixing component is used to fix the concrete material 13 to be tested. A second base plate 14 is movably arranged between the upper plate 2 and the lower plate 3. The fixing component is set on the second base plate 14. A displacement mechanism is set on the reinforcing plate 4. The displacement mechanism is connected to the second base plate 14 in a transmission manner.

[0036] In this device, the force-applying mechanism is used to apply external force to the concrete material 13 to be tested during compressive strength testing and tensile strength testing. The force-applying mechanism applies force to the first base plate 5, and the first base plate 5 transmits the force to the fixed column 6. The first slider 8 can slide in the cavity 7.

[0037] When tensile strength testing is required, one end of the concrete material 13 to be tested is first installed on the fixing component. The position of the concrete material 13 to be tested is adjusted by the displacement mechanism. Then, the tension clamping mechanism is installed on the conical force block 10. Before installation, the conical force block 10 is removed. After installation, the conical force block 10 is installed on the connecting column 9. Then, the tension clamping mechanism is used to clamp the concrete material 13 to be tested. Finally, the force is applied to the first base plate 5 by the force application mechanism. The first base plate 5 pulls the fixing column 6. The fixing column 6 moves and will pull the conical force block 10 through the connecting column 9, which will cause the first slider 8 to contact the pressure sensor 12, so that the pressure sensor 12 can measure the tension of the concrete material 13 to be tested.

[0038] When a compressive strength test is required, one end of the concrete material 13 to be tested is first installed on the fixed component. The position of the concrete material 13 to be tested is adjusted by the displacement mechanism. At this time, the tension clamping mechanism is no longer used. The concrete material 13 to be tested must contact the conical force block 10. The second base plate 14 moves until the concrete material 13 to be tested comes into contact with the pressure sensor 11. Then the second base plate 14 stops moving. The force application mechanism applies force to the first base plate 5. The first base plate 5 applies a pushing force to the fixed column 6. When the fixed column 6 moves, the connecting column 9 will move in the first through hole, so that the first slider 8 moves away from the pressure sensor 12 and comes into contact with the side wall of the cavity 7, so that the force can be transmitted to the concrete material 13 to be tested. The pressure on the concrete material 13 to be tested can be measured by the pressure sensor 11.

[0039] The scheme is further optimized by providing threaded holes on the conical force-bearing block 10 and threaded connections on the connecting column 9. The connecting column 9 is threadedly connected to the threaded holes. Several connecting holes 15 are provided on the conical force-bearing block 10. Short rods 16 are inserted into the connecting holes 15. A protective plate 17 is fixedly connected to the short rod 16. Pressure sensor 11 is located between the protective plate 17 and the conical force-bearing block 10.

[0040] The conical force-bearing block 10 and the connecting column 9 are detachably connected by threads. The short rod 16 can move within the connecting hole 15. The protective plate 17 mainly protects the pressure sensor 11. The protective plate 17 can move with the short rod 16. When conducting the compressive strength test, the protective plate 17 will not affect the pressure sensor 11.

[0041] The scheme is further optimized. The clamping mechanism includes two arc-shaped force-bearing rings 18. The inner edge of the arc-shaped force-bearing rings 18 is conical. The arc-shaped force-bearing rings 18 are adapted to the conical force-bearing blocks 10. A first connecting plate 19 is fixedly connected to the outside of the arc-shaped force-bearing rings 18. The two first connecting plates 19 are rotatably connected to the fixed rings 20. A first clamping plate 21 is fixedly connected to the first connecting plate 19. The two first clamping plates 21 are detachably connected. A first mounting hole is opened on the first clamping plate 21. A first screw 22 passes through the first mounting hole. A first nut 23 is detachably connected to the first screw 22.

[0042] Two arc-shaped force rings 18 are used to fit onto the conical force block 10, and a fixing ring 20 is used to connect two first connecting plates 19. When performing tensile strength testing, the conical force block 10 is removed, then placed between the two arc-shaped force rings 18, and then the conical force block 10 is installed on the connecting column 9. The two first clamping plates 21 are installed on the concrete material 13 to be tested and fixed with the first screw 22 and the first nut 23. During installation, the concrete material 13 to be tested cannot cause the pressure sensor 11 to generate force.

[0043] During the tensile strength test, the conical force block 10 is subjected to tensile force. Since the outer edge of the conical force block 10 is conical and the inner edge of the arc-shaped force ring 18 is conical, the arc-shaped force ring 18 will move along the surface of the conical force block 10 when subjected to tensile force. The two arc-shaped force rings 18 will move upward and downward respectively. Since the first connecting plate 19 is rotatably connected inside the fixed ring 20, with the connection point between the first connecting plate 19 and the fixed ring 20 as the fulcrum, the end of the first connecting plate 19 away from the arc-shaped force ring 18 will move towards the concrete material 13 to be tested. The upper and lower first connecting plates 19 will squeeze the concrete material 13 to be tested, thereby clamping the concrete material 13 to be tested more tightly.

[0044] The scheme is further optimized by fixing several first sleeves 24 to the first connecting plate 19, fixing a first rotating shaft 25 to the inside of the fixing ring 20, rotating the first rotating shaft 25 to the inside of the first sleeve 24, and fixing an anti-slip pad to the first clamping plate 21.

[0045] The first connecting plate 19 and the fixing ring 20 are rotatably connected by the cooperation of the first rotating shaft 25 and the first sleeve 24, and the anti-slip pad increases the friction between the first connecting plate 19 and the concrete material 13 to be tested.

[0046] The scheme is further optimized. The force-applying mechanism includes several first hydraulic cylinders 27 and several second hydraulic cylinders 29. First mounting grooves 28 are provided on both the upper plate 2 and the lower plate 3. Two first mounting grooves 28 are set correspondingly. Second sliders 30 are slidably arranged in the first mounting grooves 28. First hydraulic cylinders 27 and second hydraulic cylinders 29 are fixedly connected in both first mounting grooves 28. The first hydraulic cylinders 27 and second hydraulic cylinders 29 are located on both sides of the second sliders 30. First hydraulic cylinders 27 are used in the compression test, and second hydraulic cylinders 29 are used in the tensile test. Second through holes 31 are provided on both the upper plate 2 and the lower plate 3. The second through holes 31 communicate with the first mounting grooves 28. A first base plate 5 is fixedly connected between the two second sliders 30. The first base plate 5 passes through the second through holes 31.

[0047] The second slider 30 slides within the first mounting groove 28. When a compressive strength test is required, the first hydraulic cylinder 27 is activated, which pushes the second slider 30 to move. The two second sliders 30 push the first base plate 5 to move. When a tensile strength test is required, the second hydraulic cylinder 29 is activated, which pushes the second slider 30 to move.

[0048] The scheme is further optimized. The fixing component includes two second connecting plates 32, which are rotatably connected to the second base plate 14. A third connecting plate 33 is rotatably connected to the second connecting plate 32. A second clamping plate 34 is fixedly connected to the third connecting plate 33. The two second clamping plates 34 are detachably connected. A fixing block 35 is fixedly connected to the second base plate 14. The fixing block 35 is set to correspond to the concrete material 13 to be tested.

[0049] During installation, the concrete material to be tested 13 is brought into contact with the fixing block 35, and the concrete material to be tested 13 is placed between the two second clamping plates 34. Then the two second clamping plates 34 are connected together.

[0050] The scheme is further optimized as follows: several second sleeves 36 are fixedly connected to the second base plate 14; a second rotating shaft 37 is fixedly connected to the second connecting plate 32 and rotatably connected to the second sleeve 36; a third sleeve 38 is fixedly connected to the second connecting plate 32; a third rotating shaft 39 is fixedly connected to the third connecting plate 33 and rotatably connected to the third sleeve 38; an anti-slip pad is fixedly connected to the second clamping plate 34; a second mounting hole is opened on the second clamping plate 34; a second screw 26 passes through the second mounting hole; and a second nut 40 is detachably connected to the second screw 26.

[0051] The second connecting plate 32 is rotatably connected to the second base plate 14 through the cooperation of the second sleeve 36 and the second rotating shaft 37. The second connecting plate 32 is rotatably connected to the third connecting plate 33 through the cooperation of the third sleeve 38 and the third rotating shaft 39. The anti-slip pad can increase the friction between the concrete material 13 to be tested and the third connecting plate 33. The second screw 26 and the second nut 40 are used to connect the two second clamping plates 34.

[0052] The scheme is further optimized by providing a second mounting groove 41 on both the upper plate 2 and the lower plate 3. A third slider 42 is slidably disposed in the second mounting groove 41. A third through hole 43 is provided on both the upper plate 2 and the lower plate 3. The third through hole 43 communicates with the second mounting groove 41. The second base plate 14 is fixedly connected between the two third sliders 42 and passes through the third through hole 43.

[0053] The third slider 42 slides within the second mounting groove 41, thereby allowing the second base plate 14 to move between the upper plate 2 and the lower plate 3.

[0054] The scheme is further optimized. The displacement mechanism includes a threaded column 44 and a connecting pipe 45. The connecting pipe 45 is fixedly connected to the second base plate 14. The inner edge of the connecting pipe 45 is threaded. The threaded column 44 and the connecting pipe 45 are threadedly connected. The threaded column 44 is rotatably connected to the reinforcing plate 4. The threaded column 44 passes through the reinforcing plate 4. A motor 46 is fixedly connected to the reinforcing plate 4. A first gear 47 is fixedly connected to the output end of the motor 46. A second gear 48 is fixedly connected to the threaded column 44. The first gear 47 and the second gear 48 mesh.

[0055] Motor 46 drives the first gear 47 to rotate, the first gear 47 drives the second gear 48 to rotate, and the second gear 48 drives the threaded column 44 to rotate. Since the threaded column 44 and the connecting pipe 45 are threadedly connected, when the threaded column 44 rotates, it will cause the connecting pipe 45 to move, thereby causing the second base plate 14 to move. The part where the threaded column 44 is connected to the reinforcing plate 4 has no threads, so when the threaded column 44 rotates on the reinforcing plate 4, the two will not produce relative displacement.

[0056] The design is further optimized by providing a fourth through hole on the reinforcing plate 4, through which the threaded post 44 passes. An annular groove is provided on the reinforcing plate 4, which communicates with the fourth through hole. A limiting plate 49 is fixedly connected to the threaded post 44, and the limiting plate 49 is rotatably positioned within the annular groove.

[0057] The limiting plate 49 prevents the threaded post 44 from moving on the reinforcing plate 4.

[0058] The method of using this device is as follows: Before testing, first install one end of the concrete material 13 to be tested on the second base plate 14, then place the concrete material 13 to be tested against the fixing block 35, then place the concrete material 13 to be tested between the two second clamping plates 34, and connect the two second clamping plates 34 using the second screw 26 and the second nut 40. Start the motor 46, the motor 46 drives the first gear 47 to rotate, the first gear 47 drives the second gear 48 to rotate, the second gear 48 drives the threaded column 44 to rotate. When the threaded column 44 rotates, it will cause the connecting pipe 45 to move, thereby causing the second base plate 14 to move, and causing the concrete material 13 to be tested to move towards the conical force block 10.

[0059] If a tensile strength test is required, remove the conical force block 10, place it between the two arc-shaped force rings 18, and then install the conical force block 10 on the connecting column 9. Place the two first clamping plates 21 on the concrete material 13 to be tested and secure them with the first screws 22 and the first nuts 23. Activate the second hydraulic cylinder 29, which pushes the second slider 30 to move. The second slider 30 moves the first base plate 5, which pulls the fixing column 6. As the fixing column 6 moves, the first slider 8 contacts the pressure sensor 12. The connecting column 9 pulls the first slider 8, and the pressure sensor 12 is subjected to pressure, thus transmitting the pressure. Sensor 12 measures the tensile force on the concrete material 13 to be tested; at the same time, the conical force block 10 is subjected to tensile force. Since the outer edge of the conical force block 10 is conical and the inner edge of the arc-shaped force ring 18 is conical, when subjected to tensile force, the arc-shaped force ring 18 will move along the surface of the conical force block 10. The two arc-shaped force rings 18 will move upward and downward respectively. Since the first connecting plate 19 is rotatably connected in the fixed ring 20, with the connection point between the first connecting plate 19 and the fixed ring 20 as the fulcrum, the end of the first connecting plate 19 away from the arc-shaped force ring 18 will move towards the concrete material 13 to be tested. The upper and lower first connecting plates 19 will squeeze the concrete material 13 to be tested, thereby clamping the concrete material 13 to be tested more tightly.

[0060] If a compressive strength test is required, a tension clamping mechanism is not needed, meaning the arc-shaped force ring 18 and related structures are not required. The second base plate 14 is moved by the motor 46 until the concrete material 13 to be tested comes into contact with the pressure sensor 11. Then the second base plate 14 stops moving, and the first hydraulic cylinder 27 is activated. The first hydraulic cylinder 27 pushes the second slider 30 to move, and the second slider 30 drives the first base plate 5 to move. The first base plate 5 applies a pushing force to the fixed column 6. When the fixed column 6 moves, the connecting column 9 moves in the first through hole, causing the first slider 8 to move away from the pressure sensor 12 and to come into contact with the side wall of the cavity 7. This allows the force to be transmitted to the concrete material 13 to be tested, and the pressure on the concrete material 13 can be measured by the pressure sensor 11.
