Strength testing methods for building materials

Abstract

The invention discloses a building material strength detection method, and relates to the technical field of building material detection. A concrete block is fixedly clamped to the bottom of a strength detection component above a base, wherein the strength detection component includes a pressure sensor, and a connecting plate and the strength detection component are driven to move downward by a hydraulic cylinder. During this process, the strength detection component presses down the concrete block to detect the pressure data of the concrete block by the pressure sensor. During the downward movement of the connecting plate, two protection frames are synchronously made to approach and fit together to block the flying debris when the concrete block is broken. After the detection is completed, the output shaft of the hydraulic cylinder is reset and retracted to make the two protection frames move away from each other, and at the same time, a push plate is made to slide along the surface of a detection groove to push the concrete block broken on the surface of the detection groove to the top of a collecting groove, and then the push plate is reset and slid to the initial position, so that the next detection work can be directly carried out.

Description

Technical Field

[0001] The invention relates to the technical field of building material detection, in particular to a building material strength detection method. Background Art

[0002] Building materials, as the cornerstone of building structures, can be divided into structural materials, decorative materials and special materials according to their functions and uses. Cement boards, in particular, are an important part of structural building materials, and their frequency of use and demand are increasing day by day.

[0003] However, due to various factors such as equipment conditions, raw material quality, and operating technology level in the production process, the quality of structural building materials such as cement boards varies.

[0004] Therefore, in order to ensure the stability and safety of building structures, it is particularly important to carry out strict quality inspections on structural building materials such as cement boards. Strength testing is a key link, and specific strength testing equipment is required to evaluate the mechanical properties of the material to ensure that it meets the design requirements and usage standards.

[0005] The general strength test method for building materials is to test the maximum bearing capacity of concrete blocks by squeezing through strength test components. In this process, some concrete blocks will be squeezed and broken, resulting in broken concrete blocks easily remaining in the test area after the test, making the device body dirty and messy, which brings inconvenience to the cleaning work of the subsequent staff and is difficult to clean up. If the broken blocks are not cleaned up in time, the subsequent testing work may be inaccurate. At the same time, concrete blocks are prone to causing debris to fly out at the moment of damage, and the staff nearby are easily injured by the flying debris. This safety hazard not only threatens the health of the staff, but may also affect the smooth progress of the testing work. Summary of the invention

[0036] Automatic limit: The concrete block is fixedly clamped to the bottom of the strength detection component 13 above the base 1, and the strength detection component 13 includes a pressure sensor;

[0037] The connecting plate 5 and the strength detection assembly 13 are driven downward by the hydraulic cylinder 4. During this process, the strength detection assembly 13 presses down the concrete block to detect the pressure data of the concrete block through the pressure sensor;

[0038] Automatic protection: When the connecting plate 5 moves downward, the two protection frames 601 are simultaneously brought close to each other and fit together to block the debris that is blown away when the concrete block is broken;

[0039] Automatic cleaning: After the detection is completed, the output shaft of the hydraulic cylinder 4 is reset and retracted to move the two protective frames 601 away from each other, and at the same time, the push plate 904 slides along the surface of the detection groove 7 to push the broken concrete blocks on the surface of the detection groove 7 to the top of the collection groove 10, and then the push plate 904 is reset and slid to the initial position, and the next detection work can be carried out directly.

[0040] The present invention also provides the following building material strength detection device, including a base 1, the top of the base 1 is fixedly connected to a support frame 2, and the end of the support frame 2 away from the base 1 is fixedly connected to a support plate 3, the top of the base 1 is provided with a detection groove 7, and the side wall of the detection groove 7 is provided with a first slide groove 8, and the bottom of the connecting plate 5 is fixedly installed with a strength detection component 13.

[0041] A protection mechanism 6 is provided on the top of the support plate 3 to automatically protect the detection area during detection.

[0042] Furthermore, the protection mechanism 6 includes a protection frame 601, and both side walls of the protection frame 601 are provided with second slide grooves 602, the inner wall of the second slide groove 602 is slidably connected with a first sliding rod 603, the ends of the two first sliding rods 603 away from the protection frame 601 are fixedly connected with a fixing plate 604, the top of the fixing plate 604 is fixedly connected with a second sliding rod 605, the side wall of the protection frame 601 is provided with a limiting groove 607, the top of the protection frame 601 is penetrated with a third slide groove 606, and the first The outer wall of the second sliding rod 605 is slidably connected to the inner wall of the third sliding groove 606, the side wall of the protection frame 601 is fixedly connected with a rack 608, and the outer wall of the rack 608 is slidably connected to the inner wall of the limiting groove 607, the top of the support plate 3 is fixedly installed with a hydraulic cylinder 4, and the output shaft of the hydraulic cylinder 4 is fixedly connected to the connecting plate 5, the outer wall of the second sliding rod 605 penetrates and is slidably connected to the inside of the support plate 3, and the end of the second sliding rod 605 away from the fixed plate 604 is fixedly connected to the top of the connecting plate 5;

[0043] In this embodiment, the concrete blocks used in the building need to be tested by the strength detection device first, so as to intuitively understand whether their compressive strength meets the design requirements and use standards. If the strength of the concrete blocks is insufficient, it may cause safety hazards in the building structure during use, such as cracks, deformation or even collapse. Therefore, before the concrete blocks are put into use, it is necessary to ensure that their strength is tested;

[0044] First, the concrete block to be tested is fixed and clamped to the bottom of the strength detection component 13, and then the hydraulic cylinder 4 is driven to drive the connecting plate 5 of its output shaft to move downward, and then the connecting plate 5 will drive the concrete block to press down through the strength detection component 13, so that the concrete block will gradually move toward the inside of the detection groove 7, and at the same time, the connecting plate 5 will drive the second sliding rods 605 on both sides to move downward, and then the second sliding rod 605 will drive the fixed plate 604 to move synchronously, and then the fixed plate 604 will drive the first sliding rod 603 to move downward, and during the process, the end of the first sliding rod 603 will slide along the inner wall of the second slide groove 602. When sliding to a certain distance, since the middle part of the second slide groove 602 is set as an inclined groove, the first sliding rod 603 will squeeze the protective frame 601 through the second slide groove 602, and then the two protective frames 601 will move relative to each other at the same time after being squeezed, and then when the concrete block is inside the detection groove 7, the first sliding rod 603 will slide along the second slide groove 602 The two protective frames 601 are slid to the bottom, so that the two protective frames 601 slide and fit together. Since the inner wall of the protective frame 601 corresponds to the side wall of the connecting plate 5, the inner wall of the protective frame 601 will slide along the side wall of the connecting plate 5 during the sliding process of the protective frame 601, so that the strength detection component 13 that clamps the concrete block through the connecting plate 5 is more stable during the extrusion test. At the same time, the outer wall of the rack 608 will slide into the inside of the limiting groove 607, so that the fit of the two protective frames 601 will not be offset. In the subsequent extrusion test, the strength detection component 13 squeezes the concrete block. When the concrete block cannot withstand the pressure, it may break, and the broken debris may also be blown away. At this time, since the two protective frames 601 are merged together, the flying debris can be blocked, so that the debris stays on the surface of the detection groove 7, thereby avoiding the concrete block from breaking during the detection process. The broken debris flies out, causing physical damage to the staff, protecting the physical safety of the staff, and reducing the safety risks of the device when it is used.

[0045] As described above, the first sliding rod 603 is driven by the connecting plate 5 to slide along the inner wall of the second sliding groove 602, so that the two protection frames 601 are close to each other and fit together. In the subsequent inspection work, if the concrete blocks cannot withstand the pressure and break, they will be blocked by the protection frame 601 on the surface of the inspection groove 7 to prevent them from splashing onto the staff, thereby greatly reducing the risk of injury to the staff.

[0046] Embodiment 2, on the basis of the above embodiment, the inner wall of the first slide groove 8 is provided with a cleaning mechanism 9 to automatically clean the surface of the detection groove 7 when the detection is completed, the side wall of the detection groove 7 is provided with a collecting groove 10, and the side wall of the collecting groove 10 is fixedly connected with a fixing rod 11, and the outer wall of the fixing rod 11 is rotatably connected with a first gear 12, and the gear teeth of the first gear 12 are matched and meshed with the gear teeth of the fourth gear 913.

[0047] Furthermore, the cleaning mechanism 9 includes a horizontal plate 901, a horizontal rod 902 is fixedly connected to one side of the two horizontal plates 901, and a sliding frame 903 is slidably connected to the outer wall of the horizontal rod 902, and a push plate 904 is fixedly connected to the bottom of the sliding frame 903, and a rotating rod 905 is axially connected to the inner wall of one of the horizontal plates 901, and one end of the rotating rod 905 is fixedly connected to a first rotating plate 906, and the end of the first rotating plate 906 away from the rotating rod 905 is fixedly connected to a first rotating shaft 907, and the first rotating shaft 907 is connected to the first rotating plate 90 6 is fixedly connected to a second gear 908, an outer wall of the first rotating shaft 907 is rotatably connected to a bottom plate 909, one end of the sliding frame 903 is rotatably connected to a second rotating plate 910, and an end of the second rotating plate 910 away from the sliding frame 903 is fixedly connected to a second rotating shaft 911, an end of the second rotating shaft 911 away from the second rotating plate 910 is fixedly connected to a third gear 912, and the gear teeth of the third gear 912 are matched and meshed with the gear teeth of the second gear 908, and an outer wall of the rotating rod 905 is fixedly connected to a fourth gear 913;

[0048] In this embodiment, during the detection process, some concrete blocks usually cannot withstand the pressure and break. After the detection is completed, the output shaft of the hydraulic cylinder 4 will reset and retract, thereby driving the first sliding rod 603 to slide upward along the inner wall of the second sliding groove 602, so that the two protection frames 601 slide away from each other. At the same time, since the broken concrete block cannot maintain its original shape, it is no longer subject to the clamping force of the strength detection component 13. The broken concrete block will stay on the surface of the detection groove 7. During the reset process of the protection frame 601, the rack 608 will drive the first gear 12 to continue to rotate, and then the first gear 12 will drive the fourth gear 913 to rotate, and then the fourth gear 913 will drive the first rotating plate 906 to rotate at the same time through the rotating rod 905, so that the first rotating plate 906 drives the second gear 908 to rotate with the rotating rod 905 as the axis through the first rotating shaft 907, and the distance between the first rotating shaft 907 and the second rotating shaft 911 is limited by the bottom plate 909, so that the second rotating plate 906 The distance between the gear 908 and the third gear 912 will not change. Then, the first rotating shaft 907 will drive the third gear 912 to rotate when it moves. At the same time, the first rotating plate 906 will drive the second rotating plate 910 to move through the bottom plate 909. During the movement of the second rotating plate 910, it will rotate around the second rotating shaft 911. The outer wall of the sliding frame 903 is slidably connected to the inner wall of the first sliding groove 8, and the bottom of the push plate 904 slides in contact with the top of the detection groove 7, thereby driving the sliding frame 903 to slide along the outer wall of the cross bar 902, so that the push plate 904 will slide along the surface of the detection groove 7. During the sliding process of the push plate 904, the broken concrete blocks on the surface of the detection groove 7 will be pushed to the top of the collecting groove 10, and then fall into the inside of the collecting groove 10. After that, after the rotating rod 905 rotates half a circle, it will drive the sliding frame 903 to slide in the opposite direction along the cross bar 902, so that the push plate 904 is reset and slid to the initial position, and then the next detection work can be directly carried out;

[0049] As described above, the two protective frames 601 are reset by the connecting plate 5, so that the push plate 904 slides along the surface of the detection groove 7, and the broken concrete blocks on the surface of the detection groove 7 are pushed to the top of the collecting groove 10, and then fall into the inside of the collecting groove 10, thereby completing the cleaning of the detection groove 7 after the detection, and then the next detection work can be carried out directly, which improves the work efficiency, reduces the labor intensity of the staff, and avoids the accuracy of the next detection work being affected by the residual debris on the surface of the detection groove 7.

[0050] Working principle: first, the concrete block to be tested is fixed and clamped to the bottom of the strength detection component 13, and then the hydraulic cylinder 4 is driven to drive the connecting plate 5 of its output shaft to move downward through the hydraulic cylinder 4, and then the connecting plate 5 will drive the concrete block to press down through the strength detection component 13, so that the concrete block will gradually move toward the inside of the detection groove 7, and at the same time, the connecting plate 5 will drive the second sliding rods 605 on both sides to move downward, and then the second sliding rod 605 will drive the fixed plate 604 to move synchronously, and then the fixed plate 604 will drive the first sliding rod 603 to move downward, and during the process, the end of the first sliding rod 603 will slide along the inner wall of the second slide groove 602. When sliding to a certain distance, since the middle part of the second slide groove 602 is set as an inclined groove, the first sliding rod 603 will squeeze the protective frame 601 through the second slide groove 602, and then the two protective frames 601 will move relative to each other at the same time after being squeezed, and then when the concrete block is inside the detection groove 7, the first sliding rod 603 will slide to the bottom along the second slide groove 602, so that the two The two protective frames 601 slide and fit together. Since the inner wall of the protective frame 601 corresponds to the side wall of the connecting plate 5, the inner wall of the protective frame 601 will slide and fit along the side wall of the connecting plate 5 during the sliding process of the protective frame 601, so that the strength detection component 13 that clamps the concrete block is more stable during the extrusion test through the connecting plate 5. At the same time, the outer wall of the rack 608 will slide into the inside of the limiting groove 607, so that the fit of the two protective frames 601 will not be offset. In the subsequent extrusion test, the strength detection component 13 squeezes the concrete block. When the concrete block cannot withstand the pressure, it may break, and the broken debris may also be blown away. At this time, since the two protective frames 601 are merged together, the flying debris can be blocked, so that the debris stays on the surface of the detection groove 7, so as to avoid the concrete block being broken during the detection process. After the broken debris flies out, causing physical damage to the staff, the physical safety of the staff is protected, and the safety risk hidden dangers of the device when in use are reduced, thereby greatly reducing the risk of injury to the staff;

[0051] During the detection process, some concrete blocks usually cannot withstand the pressure and break. After the detection is completed, the output shaft of the hydraulic cylinder 4 will reset and retract, thereby driving the first sliding rod 603 to slide upward along the inner wall of the second sliding groove 602, so that the two protection frames 601 slide away from each other. At the same time, since the broken concrete block cannot maintain its original shape, it is no longer subject to the clamping force of the strength detection component 13. The broken concrete block will stay on the surface of the detection groove 7. During the reset process of the protection frame 601, the rack 608 will drive the first gear 12 to continue to rotate, and then the first gear 12 will drive the fourth gear 913 to rotate, and then the fourth gear 913 will drive the first rotating plate 906 to rotate at the same time through the rotating rod 905, so that the first rotating plate 906 drives the second gear 908 to rotate with the rotating rod 905 as the axis through the first rotating shaft 907, and the distance between the first rotating shaft 907 and the second rotating shaft 911 is limited by the bottom plate 909, so that the second gear 9 08 and the third gear 912 will not change, and then the first rotating shaft 907 will drive the third gear 912 to rotate when it moves, and at the same time, the first rotating plate 906 will drive the second rotating plate 910 to move through the bottom plate 909. During the movement of the second rotating plate 910, it will rotate around the second rotating shaft 911 as the axis, and the outer wall of the sliding frame 903 is slidably connected to the inner wall of the first sliding groove 8, and the bottom of the push plate 904 slides in contact with the top of the detection groove 7, thereby driving the sliding frame 903 to slide along the outer wall of the cross bar 902, so that the push plate 904 will slide along the surface of the detection groove 7. During the sliding process of the push plate 904, the broken concrete blocks on the surface of the detection groove 7 will be pushed to the top of the collecting groove 10, and then fall into the inside of the collecting groove 10. After that, after the rotating rod 905 rotates half a circle, it will drive the sliding frame 903 to slide in the opposite direction along the cross bar 902, so that the push plate 904 is reset and slides to the initial position, and then the next detection work can be carried out directly.
