Concrete compressive strength test detection device

Abstract

The invention discloses a concrete compressive strength test detection device, and relates to the technical field of compressive strength detection. After a tester puts in a concrete block, a pressure applying element is started to apply pressure to the concrete block, the concrete block and a pressure applying position cannot be accurately positioned, so that the pressure resistance detection data of the concrete block has a relatively large error, and through the cooperation of a side baffle and a pressure plate, after the pressure plate is in contact with the top of the concrete block, the work of a hydraulic cylinder is stopped; according to the technical scheme, under the cooperation of the sliding connection between the sliding rod and the sliding groove plate and the elastic deformation characteristic of the elastic bent plate, the limitation on the concrete block is reduced, the position adjustment of the concrete block is facilitated, meanwhile, the concrete corresponds to the pressure center position by utilizing the contact between the side baffle and the edge position of the concrete block, and the phenomenon that in the existing pressure detection process, the pressure is not influenced is avoided. When pressure detection is directly carried out, position deviation is caused, the pressed position of the concrete block deviates from the central position, and errors of test detection data are caused.

Description

Technical Field

[0001] The present invention relates to the technical field of compressive testing, and specifically to a testing device for concrete compressive strength testing. Background Art

[0002] The concrete compressive strength refers to the ultimate strength of a specimen under standard curing conditions when it is compressed to failure on a compression testing machine, which reflects the ability of the concrete to resist compressive deformation. The concrete compressive strength test is a key test item for evaluating the mechanical properties of concrete and is widely used in fields such as building engineering quality control and material property research. By applying axial pressure to the concrete specimen on a compression testing machine until the specimen fails, the maximum pressure value it can withstand is measured, and then the compressive strength of the concrete is calculated. The concrete compressive strength is the core index for measuring the mechanical properties of concrete, referring to the ability of the concrete to resist failure under axial pressure, usually expressed as the maximum pressure value that can be borne per unit area; During the existing compressive tests, after the test personnel place the concrete block, they start the pressing element to press the concrete block, but it is impossible to accurately position the concrete block and the pressing position, resulting in an offset between the concrete block and the pressing center position, and causing a large error in the compressive test data of the concrete block. Summary of the Invention

[0003] To achieve the above objectives, the present invention is realized through the following technical solutions: A testing device for concrete compressive strength testing, comprising: A frame body, on the top of which a control cabinet is fixedly installed, and on the top inner wall of the frame body, a hydraulic cylinder is fixedly installed; A slag collection mechanism, which is installed inside the frame body and is located directly below the hydraulic cylinder; A support mechanism, which is used to support the concrete block to be tested and is installed inside the slag collection mechanism; A connecting column is fixedly installed at the output end of the hydraulic cylinder. One end of the connecting column away from the hydraulic cylinder is fixedly installed with a top plate. Column holes are formed at the corners of the top of the top plate, and sliding columns are slidably installed at the column holes of the top plate. The bottom end of the sliding column is fixedly installed with a chute plate. A plate groove is formed at the center of the bottom of the chute plate, and rod grooves are formed on both sides of the top of the chute plate. Slide rods are slidably installed at the rod grooves of the chute plate. The bottom end of the slide rod is fixedly connected with a pressure plate. The bottom of the pressure plate is adapted to the plate groove. Rectangular grooves are formed on both sides of the chute plate, and side baffles are slidably installed at the rectangular grooves of the chute plate. Through the cooperation of the side baffles and the pressure plate, after the pressure plate contacts the top of the concrete block, the operation of the hydraulic cylinder is stopped, enabling the experimenter, under the sliding connection between the slide rod and the chute plate and the elastic deformation characteristics of the elastic curved plate, to reduce the restriction on the concrete block and facilitate the adjustment of the position of the concrete block. At the same time, by using the contact between the side baffle and the edge position of the concrete block, the concrete is made to correspond to the pressure application center position, avoiding the situation in the current pressure application test where direct pressure application detection causes a position deviation, resulting in the pressure application position of the concrete block deviating from the center position and causing errors in the test detection data. The bottom ends of the side baffles are inclined downward from top to bottom on both sides. Elastic curved plates are fixedly installed at the positions of the top of the chute plate close to the rectangular grooves, and the tops of the elastic curved plates are fixedly connected to the inner walls of the side baffles.

[0004] A protective plate is fixedly installed at the bottom of the outer side of the frame body, and a rotating plate is rotatably installed on the outer side of the protective plate. The rotating plate and the protective plate cooperate to enclose the slag collection mechanism and the support mechanism inside.

[0005] Preferably, the slag collection mechanism includes a bottom plate. The bottom of the bottom plate is fixedly connected to the inner wall of the frame body. Support bin plates are fixedly installed on both sides of the top of the bottom plate. A slag dropping bin is fixedly installed on the top of the support bin plate. There is a space between the bottom of the slag dropping bin and the bottom plate, and powder dropping grooves are uniformly formed at the bottom of the slag dropping bin. Through the cooperation of the powder dropping grooves and the slag dropping bin, during the compressive test, the concrete debris broken and dropped during the experiment is collected in a graded manner, avoiding the situation during the experiment where the concrete materials broken by pressure accumulate at the support position, resulting in the need to clean the support position when putting the concrete block for the experiment again, and avoiding the residual concrete debris contacting the bottom of the concrete block and causing the concrete block to tilt, affecting the normal progress of the experiment. A powder collection groove is slidably installed in the gap between the slag dropping bin and the bottom plate, and the top of the powder collection groove is in close contact with the bottom of the slag dropping bin.

[0006] Preferably, plate grooves are formed on both sides of the slag dropping bin, and an empty groove is formed at the bottom of the slag dropping bin near the rotating plate. A clamping strip is fixedly installed on the inner wall of the slag dropping bin away from the rotating plate, and an inclined groove plate is clamped on the inner wall of the slag dropping bin. The top of the inclined groove plate is an inclined surface that slopes downward near the rotating plate, and through grooves are evenly formed on the top of the inclined groove plate. Through the cooperation of the through grooves and the inclination of the inclined groove plate, when large debris falls off under pressure, it drops onto the top of the inclined groove plate. The inclined groove plate blocks it, causing the large debris to roll down along the inclined surface and then be blocked by the material blocking plate, so as to centrally collect the large debris, avoid the mixing of large debris and powder, prevent the large debris from causing material jamming, and affect the cleaning of the debris. The end of the bottom of the inclined groove plate away from the rotating plate contacts the top of the clamping strip, and a material blocking plate is fixedly installed at the end of the top of the inclined groove plate near the rotating plate.

[0007] Preferably, the support mechanism includes inclined panels. The number of the inclined panels is two and they are fixedly installed at the plate grooves of the slag dropping bin. Side support plates are fixedly installed on the sides of the bottoms of the inclined panels away from each other, and the bottoms of the side support plates are fixedly connected to the inner wall of the frame body. Connecting plates are fixedly installed at the bottoms of the inclined panels. The connecting plates are symmetrically installed along the axial center position of the inclined panels, and the ends of the connecting plates away from the inclined panels are fixedly connected to the inner wall of the slag dropping bin. Through the cooperation of the inclined surfaces of the inclined panels and the inclined plates, using their inclined surfaces that gradually incline inward from top to bottom, when pressing the concrete block, the pressure is transmitted to the inclined plate through the support beam. Utilizing the sliding adaptation of the inclined plate and the inclined surface of the inclined panel, the vertically downward force is guided obliquely to both sides, and with the triangular support of the inclined support plate, the bearing capacity of the support mechanism is improved. While ensuring the smooth dropping of the fragmented concrete blocks, the support for the test material is maintained, and the inclined panels are located above the inclined groove plates.

[0008] Preferably, the opposite surfaces of the inclined panels are inclined surfaces that incline inward from top to bottom, and inclined plates are slidably installed on the inclined surfaces of the inclined panels. Card slots are evenly formed at the tops of the inclined plates, and a support beam is clamped between the inclined plates. Diagonal support plates are fixedly installed at the bottoms of the support beams. The ends of the diagonal support plates away from the support beams are closely attached to the opposite surfaces of the inclined plates. Tooth grooves are evenly formed along the axis at the tops of the support beams. Through the cooperation of the tooth grooves of the support beam and the limiting strips, during the process of supporting the concrete block, the tooth grooves contact the bottom of the concrete block through the tooth grooves, increasing the friction with the bottom of the concrete block. At the same time, the limiting strips on both sides limit the position of the concrete block during the pressing process, avoiding the fragmented concrete blocks moving to both sides under pressure after being pressed and broken, resulting in the concrete blocks flying out under pressure and causing injury to personnel. Limiting strips are fixedly connected to the tops of the inclined plates, and the tops of the limiting strips are arc-shaped.

[0009] The present invention provides a device for testing the compressive strength of concrete. It has the following beneficial effects: 1. The concrete compressive strength test and detection device, through the cooperation of the side baffle and the pressure plate, stops the operation of the hydraulic cylinder after the pressure plate contacts the top of the concrete block, enabling the experimenter, under the sliding connection of the sliding rod and the chute plate and in cooperation with the elastic deformation characteristics of the elastic curved plate, to reduce the restrictions on the concrete block, facilitating the adjustment of the position of the concrete block. At the same time, by using the contact between the side baffle and the edge position of the concrete block, the concrete is made to correspond to the pressure application center position, avoiding the situation in the current pressure application detection process where direct pressure application detection leads to position deviation, causing the pressure application position of the concrete block to deviate from the center position and resulting in errors in the test and detection data.

[0010] 2. The concrete compressive strength test and detection device, through the cooperation of the powder dropping groove and the slag dropping bin, during the compressive test, classifies and collects the concrete debris that breaks and falls during the experiment, avoiding the situation during the experiment where the concrete materials that are crushed under pressure accumulate at the support position, resulting in the need to clean the support position when the concrete block is placed again for the experiment, and avoiding the residual concrete debris contacting the bottom of the concrete block, causing the concrete block to tilt and affecting the normal progress of the experiment.

[0011] 3. The concrete compressive strength test and detection device, through the through groove and inclination of the inclined chute plate, after the large debris falls off under pressure, it drops onto the top of the inclined chute plate, is blocked by the inclined chute plate, and rolls down along the inclined plane, and then is blocked by the baffle plate, collecting the large debris centrally, avoiding the mixing of the large debris with the powder and preventing the large debris from causing material jamming and affecting the cleaning of the debris.

[0012] 4. The concrete compressive strength test and detection device, through the inclined plane of the inclined panel and the inclined plate, using its inclined plane that gradually inclines inward from top to bottom, when applying pressure to the concrete block, the pressure is transmitted to the inclined plate through the support beam, and by the sliding adaptation of the inclined plate and the inclined plane of the inclined panel, the vertically downward force is guided obliquely to both sides, and in cooperation with the triangular support of the inclined strut plate, the bearing capacity of the support mechanism is improved, while ensuring the smooth dropping of the broken concrete block and maintaining the support for the test material.

[0013] 5. The concrete compressive strength test and detection device, through the cooperation of the tooth groove of the support beam and the limit strip, during the process of supporting the concrete block, contacts the bottom of the concrete block through the tooth groove, increasing the friction with the bottom of the concrete block. At the same time, the limit strips on both sides limit the position of the concrete block during the pressure application process, avoiding the situation where after pressure application and fragmentation, the broken concrete block moves to both sides under pressure, causing the concrete block to fly out under pressure and resulting in injury to personnel.

Detailed implementation manners

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0017] The first embodiment is as Figures 1 to 4 shown. The present invention provides a technical solution: A device for testing the compressive strength of concrete, comprising: A frame body 1, on the top of which a control cabinet 4 is fixedly installed, and on the top of the inner wall of the frame body 1, a hydraulic cylinder 6 is fixedly installed; A slag collection mechanism 2, which is installed inside the frame body 1 and is located directly below the hydraulic cylinder 6; A support mechanism 3, which is used to support the concrete block to be tested and is installed inside the slag collection mechanism 2; A connecting column 8 is fixedly installed at the output end of the hydraulic cylinder 6. One end of the connecting column 8 away from the hydraulic cylinder 6 is fixedly installed with a top plate 9. Column holes are provided at the corners of the top of the top plate 9, and sliding columns 11 are slidably installed at the column hole positions of the top plate 9. A bottom end of the sliding column 11 is fixedly installed with a chute plate 13. A plate groove is provided at the center position of the bottom of the chute plate 13, and rod grooves are provided on both sides of the top of the chute plate 13. Slide rods 12 are slidably installed at the rod groove positions of the chute plate 13. When the hydraulic cylinder 6 is started and the pressing plate 15 contacts the top of the concrete, the position between the concrete and the pressing plate 15 is visually inspected by the tester, and the position of the concrete block is adjusted so that the pressing plate 15 is at the center position of the top of the concrete and the side baffle 14 contacts both side edges of the concrete block. Subsequently, the hydraulic cylinder 6 drives the top plate 9 to move downward through the connecting column 8. Since the pressing plate 15 is restricted by the concrete and cannot move downward, at this time, the top plate 9 moves downward, causing the sliding column 11 to slide at the column hole of the top plate 9, bringing the top plate 9 closer to the top of the chute plate 13 until the top plate 9 fits against the top of the chute plate 13. The bottom end of the slide rod 12 is fixedly connected to the pressing plate 15, which is adapted to the plate groove at the bottom of the pressing plate 15. Rectangular grooves are provided on both sides of the chute plate 13, and side baffles 14 are slidably installed at the rectangular groove positions of the chute plate 13. The bottom ends of the side baffles 14 are inclined from top to bottom to both sides. Elastic curved plates 10 are fixedly installed at positions of the top of the chute plate 13 close to the rectangular grooves. Subsequently, the output end of the hydraulic cylinder 6 drives the top plate 9 to continue to move downward, increasing the contact pressure between the side baffle 14 and the concrete block, causing the side baffle 14 to slide at the rectangular groove of the chute plate 13 and transmitting the pressure to the elastic curved plate 10, causing the elastic curved plate 10 to stretch and deform. When the side baffle 14 moves upward, the pressing plate 15 moves upward together with the sliding of the side baffle 14, causing the pressing plate 15 to be stuck in the plate groove of the chute plate 13. The pressure of the hydraulic cylinder 6 is sequentially transmitted to the top of the concrete through the connecting column 8, the top plate 9, the chute plate 13, and the pressing plate 15 to perform a pressure test on the concrete. The top of the elastic curved plate 10 is fixedly connected to the inner wall of the side baffle 14.

[0018] A protective plate 5 is fixedly installed at the bottom outside the frame body 1, and a rotating plate 7 is rotatably installed on the outside of the protective plate 5. The rotating plate 7 and the protective plate 5 cooperate to enclose the slag collection mechanism 2 and the support mechanism 3 inside.

[0019] Second embodiment, on the basis of the first embodiment, please refer to Figures 8 to 9As shown in the figure, the slag collection mechanism 2 includes a bottom plate 21. The bottom of the bottom plate 21 is fixedly connected to the inner wall of the frame body 1. On both sides of the top of the bottom plate 21, support bin plates 25 are fixedly installed. The top of the support bin plate 25 is fixedly installed with a slag dropping bin 23. There is a space between the bottom of the slag dropping bin 23 and the bottom plate 21. The slag dropping bin 23 provides a collection space for the crushed concrete debris that is crushed under pressure and drops. During the compressive strength test, the crushed concrete debris is concentrated and dropped into the slag dropping bin 23 for collection, preventing the debris from concentrating at the placement position, so that the test personnel need to clean the placement position during each test. The bottom of the slag dropping bin 23 is evenly provided with powder dropping grooves 28. A powder collection groove 26 is slidably installed in the gap between the slag dropping bin 23 and the bottom plate 21. The top of the powder collection groove 26 is closely attached to the bottom of the slag dropping bin 23.

[0020] On both sides of the slag dropping bin 23, plate grooves are provided. At the bottom of the slag dropping bin 23 near one side of the rotating plate 7, an empty groove is provided. On the side of the inner wall of the slag dropping bin 23 away from the rotating plate 7, a clamping strip 27 is fixedly installed. An inclined groove plate 24 is clamped on the inner wall of the slag dropping bin 23. The top of the inclined groove plate 24 is an inclined surface that slopes downward near the rotating plate 7. The top of the inclined groove plate 24 is evenly provided with through grooves. After the crushed concrete debris falls into the slag dropping bin 23, it first contacts the top of the inclined groove plate 24. Through the cooperation of the inclination angle of the inclined groove plate 24 and the evenly arranged through grooves at the top, larger concrete blocks are blocked, enabling the powder and small fragments to pass through the through grooves and fall on the top of the inner wall of the slag dropping bin 23. Then the powder passes through the powder dropping grooves 28 of the slag dropping bin 23 and enters the powder collection groove 26 for collection. The large concrete blocks slide down along the inclined surface of the inclined groove plate 24. Through the blocking of the baffle plate 22, the large concrete blocks are collected. The end of the bottom of the inclined groove plate 24 away from the rotating plate 7 contacts the top of the clamping strip 27. At the end of the top of the inclined groove plate 24 near the rotating plate 7, a baffle plate 22 is fixedly installed.

[0021] For the third embodiment, on the basis of the first and second embodiments, please refer to Figures 5 to 7 As shown in the figure, the support mechanism 3 includes inclined panels 32. The number of the inclined panels 32 is two and they are fixedly installed at the plate grooves of the slag dropping bin 23. On the sides of the bottoms of the inclined panels 32 that are far away from each other, side support plates 31 are fixedly installed. The bottoms of the side support plates 31 are fixedly connected to the inner wall of the frame body 1. The test personnel place the concrete material to be tested on the top of the support beam 33, making the support beam 33 cooperate with the inclined support plate 34. By using the support beam 33 to contact the bottom of the concrete, in combination with the connection between the inclined support plate 34 and the support beam 33, and the inclined support plate 34 forms a triangular support between the support beam 33 and the inclined plate 36, improving the compressive capacity of the support beam 33. On the bottoms of the inclined panels 32, connecting plates 37 are fixedly installed. The connecting plates 37 are symmetrically installed along the axial center position of the inclined panels 32. The ends of the connecting plates 37 away from the inclined panels 32 are fixedly connected to the inner wall of the slag dropping bin 23. And the inclined panels 32 are located above the inclined groove plate 24.

[0022] The opposite faces of the inclined panel 32 are inclined planes that slope inwards from top to bottom, and inclined plates 36 are slidably mounted at the inclined plane positions of the inclined panel 32. Card slots are evenly formed at the tops of the inclined plates 36, and a support beam 33 is clamped between the inclined plates 36. Diagonal bracing plates 34 are fixedly mounted at the bottoms of the support beam 33. One end of the diagonal bracing plate 34 away from the support beam 33 is in close contact with the opposite faces of the inclined plates 36. The intervals between the support beams 33 provide a falling gap for the concrete that breaks under pressure testing, enabling the broken concrete under the compression test to fall through the intervals and enter the slag collection mechanism 2 for collection. At the same time, during the pressure application test, through the cooperation of the tooth grooves at the top of the support beam 33 and the limit strips 35, the tooth grooves are used to increase the friction between the bottom of the concrete block and the support beam 33. At the same time, the limit strips 35 position the concrete block, preventing the concrete block from sliding and flying out under pressure and causing injury to personnel. Tooth grooves are evenly formed along the axial direction at the top of the support beam 33, and limit strips 35 are fixedly connected to the tops of the inclined plates 36. The tops of the limit strips 35 are arc-shaped.

[0023] During use, the tester opens the rotating plate 7, places the concrete block to be tested on the top of the support mechanism 3, and the support mechanism 3 provides support for the concrete. Subsequently, the worker starts the hydraulic cylinder 6 through the control cabinet 4, causing the hydraulic cylinder 6 to drive the connecting column 8 to move downward, so that the pressure plate 15 contacts the top of the concrete. Subsequently, the worker adjusts the position of the concrete according to the contact position, making the concrete in the central position of the pressure application. Then the rotating plate 7 is closed, and the worker makes the hydraulic cylinder 6 continue to move downward through the control cabinet 4, gradually increasing the pressure applied to the concrete until the concrete breaks, and detecting the maximum pressure resistance of the concrete. At the same time, the support mechanism 3 cooperates with the slag collection mechanism 2 to collect the broken concrete slag that falls.

[0024] When starting the hydraulic cylinder 6 to make the pressure plate 15 contact the top of the concrete, the tester visually observes the position between the concrete and the pressure plate 15 and adjusts the position of the concrete block, making the pressure plate 15 in the central position at the top of the concrete and making the side baffle 14 contact the two side edges of the concrete block. Subsequently, the hydraulic cylinder 6 drives the top plate 9 to move downward through the connecting column 8. Since the pressure plate 15 is restricted by the concrete and cannot move downward, at this time, the top plate 9 moves downward, causing the sliding column 11 to slide at the column hole of the top plate 9, making the top plate 9 approach the top of the chute plate 13 until the top plate 9 fits with the top of the chute plate 13. Subsequently, the output end of the hydraulic cylinder 6 drives the top plate 9 to continue to move downward, increasing the contact pressure between the side baffle 14 and the concrete block, causing the side baffle 14 to slide in the rectangular groove of the chute plate 13 and transmitting the pressure to the elastic curved plate 10, causing the elastic curved plate 10 to stretch and deform. When the side baffle 14 moves upward, the pressure plate 15 moves upward together with the sliding of the side baffle 14, making the pressure plate 15 snap into the plate groove of the chute plate 13. The pressure of the hydraulic cylinder 6 is sequentially transmitted to the top of the concrete through the connecting column 8, the top plate 9, the chute plate 13 and the pressure plate 15 to perform pressure testing on the concrete.

[0025] In the support mechanism 3, the tester places the concrete material to be tested on the top of the support beam 33, making the support beam 33 cooperate with the inclined support plate 34. By using the support beam 33 to contact the bottom of the concrete, and in combination with the connection between the inclined support plate 34 and the support beam 33, and the inclined support plate 34 forms a triangular support between the support beam 33 and the inclined plate 36, which improves the compressive capacity of the support beam 33. At the same time, the interval between the support beams 33 provides a falling gap for the concrete crushed under pressure testing, so that the concrete crushed under the compressive test can fall through the interval and enter the slag collection mechanism 2 for collection. Meanwhile, during the pressure testing process, through the cooperation between the tooth grooves on the top of the support beam 33 and the limiting strip 35, the tooth grooves are used to increase the friction force between the bottom of the concrete block and the support beam 33. At the same time, the limiting strip 35 positions the concrete block to prevent the concrete block from sliding and flying out during compression, causing injury to personnel.

[0026] In the slag collection mechanism 2, the slag falling bin 23 provides a collection space for the concrete debris crushed and fallen under pressure, so that the concrete debris crushed during the compressive test is concentrated and falls into the slag falling bin 23 for collection, avoiding the debris concentrating at the placement position, resulting in the tester having to clean the placement position every time during the test. At the same time, after the crushed concrete debris falls into the slag falling bin 23, it first contacts the top of the inclined chute plate 24. Through the cooperation between the inclination angle of the inclined chute plate 24 and the through grooves evenly opened at the top, larger concrete blocks are blocked, enabling the powder and small fragments to pass through the through grooves and fall on the top of the inner wall of the slag falling bin 23. Then the powder passes through the powder falling groove 28 of the slag falling bin 23 and enters the powder collection groove 26 for collection. The large concrete blocks slide down along the inclined surface of the inclined chute plate 24 and are collected by being blocked by the baffle plate 22.
