Description

Technical Field

[0001] The invention relates to the technical field of concrete quality detection, in particular to a concrete quality safety detection method for building construction. Background Art

[0002] Housing construction refers to a project with a roof, beams, columns, walls, foundations and internal space that can meet people's needs for production, residence, study and public activities. It is well known that the most commonly used material in housing construction is concrete. The quality of concrete not only affects the safety of the housing structure but also has a great impact on the cost of the housing construction project. Therefore, concrete quality testing is one of the important links in the entire testing work.

[0003] Currently, the commonly used method for concrete quality and safety testing is the specimen method. A sample of concrete to be used for pouring is placed in a test mold. After incubation for 28 hours, it is subjected to a compression test until it breaks. The pressure that the concrete sample can withstand before breaking is observed to determine whether the quality of the concrete meets the standard.

[0004] However, there are still several problems in the process of using the specimen method to conduct safety testing on concrete:

[0005] 1. In the actual testing process, the concrete quality safety testing device in the prior art often directly sets clamps that can move toward each other in the horizontal direction to clamp and fix the concrete test block. However, this fixing method has a poor fixing effect and cannot ensure that the concrete test block can be fixed directly under the pressing plate, so that the pressing plate is prone to tilting and sliding when applying pressure to the concrete test block, which affects the safety detection of the concrete test block and also poses a great safety hazard.

[0006] 2. During the actual testing process, the concrete quality safety testing device in the prior art cannot shield the debris splashed out when the concrete test block is broken. The splashed debris may cause personal injury to the staff, and the safety is low. Summary of the invention

[0007] The purpose of the present invention is to provide a method for detecting the quality and safety of concrete for building construction, so as to solve the problems mentioned in the above-mentioned background technology.

The positioning operation of the concrete test block can be completed, and under the action of the elastic potential energy of the four springs, the concrete test block can be initially fixed in four directions of front, back, left and right. The operation is simple and convenient. After the positioning is completed, the concrete test block is just below the pressing plate.

[0028] 2. In the present invention, after the four clamping plates are respectively in contact with the front, back, left and right sides of the concrete test block, as the spring 1 is squeezed, the moving block 1 will move relative to the clamping plate. In this process, under the hinged action of the hinged plate, the hinged block 2 will drive the abutment block to move downward, so as to further assist in fixing the concrete test block in the vertical direction. Multiple fixations can achieve better fixing effects, making the strength quality testing process of the concrete test block more stable and more practical.

[0029] 3. When the motor of the present invention is turned on and the moving block 1 is driven to move, the rack row 1 will also be moved synchronously. Under the meshing action of the rack row 1, the gear and the rack row 2, the four shielding plates can be extended to the top of the testing platform. Together with the four arc-shaped baffles, the concrete test block can be shielded in the front, back, left and right directions before the strength test is performed. This avoids the problem of broken concrete debris splashing in the process of the concrete test block being tested by the pressing plate being lowered, which may cause harm to the workers' bodies, and has higher safety performance.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] For example, see Figures 1 to 9The present invention provides a method for detecting the quality and safety of concrete for building construction, as follows:

[0042] Place the concrete test block on the test bench 1, turn on the motor 41, and drive the turntable 39 to rotate under the meshing action of the worm wheel 45 and the worm 46, so that the moving block 1 37 moves to a position close to the center of the test bench 1 until all four clamping plates 12 are in contact with the concrete test block, and then the concrete test block can be positioned directly below the pressing plate 6;

[0043] At this time, under the action of the four clamping plates 12, the concrete test block can be fixed from the front, back, left and right directions. At the same time, the abutment block 21 will also drop to a position abutting against the upper surface of the concrete test block, so as to fix it twice in the vertical direction.

[0044] When the motor 41 is turned on and the moving block 1 37 is driven to move toward the center of the test platform 1, the rack row 1 31 is also driven to move synchronously. Under the meshing action of the rack row 1 31, the gear 35 and the rack row 2 33, the four shielding plates 24 can be extended to the top of the test platform 1, and cooperate with the four arc-shaped baffles 8, that is, before the concrete test block is tested for strength, it can be shielded in the four directions of front, back, left and right;

[0045] Control the hydraulic assembly 4 to drive the pressure plate 6 to descend. Under the pressure of the pressure plate 6, the strength, quality and safety inspection operation can be performed on the positioned concrete test block until the concrete test block is broken. By observing the value displayed by the pressure sensor 47 displayed on the display 5, it can be determined whether the concrete test block meets the standard.

[0046] It is worth noting that the intelligent livestock and veterinary inspection method adopts a testing platform 1, the lower surface of the testing platform 1 is fixedly connected with a stabilizing member 44, the surface of the testing platform 1 is slidably connected with four shielding plates 24, the lower surface of the testing platform 1 is fixedly installed with a control box 2, the control box 2 is provided with fixing components for positioning and fixing concrete test blocks, and the testing platform 1 is provided with auxiliary components and shielding components.

[0047] The fixed component includes a protective shell 40 fixedly mounted on the inner wall of the control box 2, the surface of the protective shell 40 is connected to a rotating rod 38 for fixed-axis rotation, the end of the rotating rod 38 extending out of the protective shell 40 is fixedly connected to a rotating disk 39, the surface of the rotating disk 39 is provided with four arc-shaped slots 43 distributed in a circumferential array, the four arc-shaped slots 43 are all slidably connected with a moving column 36, the end of the moving column 36 extending out of the arc-shaped slot 43 is fixedly connected to a moving block 1 37, the upper surface of the moving block 1 37 is fixedly connected to a connecting block 29, the upper surface of the connecting block 29 is fixedly connected to a moving block 2 9, and the upper surface of the moving block 2 9 is fixedly connected to a connecting plate 1 13;

[0048] A telescopic rod 14 is arranged on the surface of the connecting plate 13, a clamp 12 is fixedly connected to the end of the telescopic rod 14, a spring 15 is arranged between the clamp 12 and the telescopic rod 14, a slider 11 is fixedly connected to the lower surface of the clamp 12, and a slide groove 10 for the slider 11 to slide and adapt is provided on the surface of the moving block 29.

[0049] The lower surface of the detection platform 1 is fixedly connected with a connecting column 26, the end of the connecting column 26 is fixedly connected with a limiting plate 27, the surface of the limiting plate 27 is provided with a sliding groove 2 for the sliding and adapting moving block 1 37, and the surface of the detection platform 1 is provided with a rectangular notch 7 for the sliding and adapting moving block 2 9 and the connecting block 29;

[0050] A motor 41 is fixedly mounted on the inner wall of the control box 2, and the output shaft of the motor 41 is fixedly connected to a rotating shaft 42, and the end of the rotating shaft 42 extending into the protective shell 40 is fixedly connected to a worm 46, and the end of the rotating rod 38 extending into the protective shell 40 is provided with a worm wheel 45 meshing with the worm 46.

[0051] More specifically, when this embodiment is used: first, a sample of concrete for pouring is placed in a square test mold, and after culturing for 28 hours, a concrete test block is obtained. Figure 2 As shown, the concrete test block is placed on the testing platform 1 from the side of the testing platform 1.

[0052] like Figure 5 , Figure 6 and Fig. 9 As shown, the motor 41 is turned on to drive the rotating shaft 42 to rotate. Under the meshing action of the worm wheel 45 and the worm 46, the rotating rod 38 and the rotating disk 39 are driven to rotate synchronously. As the rotating disk 39 rotates, the position of the arc-shaped notch 43 on its surface will change. Since the moving block 37 fixed on the upper surface of the moving column 36 is limited by the limiting plate 27, the arc-shaped notch 43 at this time will produce relative movement with the moving column 36, and the moving column 36 drives the moving block 37 to move to a position close to the center of the rotating disk 39.

[0053] like Figure 2 , Figure 3 and Figure 5As shown, in this process, as the moving block 1 37 moves, the connecting block 29 and the moving block 2 9 will be driven to move synchronously, so that the four clamping plates 12 can be moved from the four directions of front, back, left and right to the direction close to the center of the testing platform 1. When the clamping plates 12 come into contact with the concrete test block, the concrete test block will be pushed to the center position of the testing platform 1 until the four clamping plates 12 come into contact with the four sides of the concrete test block, the concrete test block will be pushed to the center position of the testing platform 1. At this time, as the moving block 1 37 continues to move, the spring 15 will be compressed. Under the action of the elastic potential energy of the spring 15, the positioning and preliminary fixation of the concrete test block can be completed. The operation is simple and convenient. After the concrete test block is positioned, it will be located just below the pressing plate 6. When the pressing plate 6 is subsequently lowered for strength, quality and safety testing, it will not tilt and slide due to uneven force on the surface of the concrete test block.

[0054] Furthermore, a support platform 3 is fixedly installed on the upper surface of the detection platform 1, a hydraulic component 4 is arranged on the surface of the support platform 3, an output end of the hydraulic component 4 is fixedly connected to a pressure plate 6, a pressure sensor 47 is arranged on the upper surface of the pressure plate 6, a display 5 is arranged on the support platform 3, and a controller 22 is also arranged on the support platform 3.

[0055] Control the hydraulic assembly 4 to drive the pressing plate 6 to descend. Under the pressure of the pressing plate 6, the strength, quality and safety testing operation can be performed on the positioned concrete test block until the concrete test block is broken. By observing the pressure value displayed on the display 5, it can be judged whether the concrete test block meets the standard.

[0056] Furthermore, the auxiliary component includes a connecting plate 2 fixedly connected to the surface of the connecting plate 13, the surface of the connecting plate 2 is slidably connected to a limiting rod 18, one end of the limiting rod 18 is fixedly connected to a cushion block, the other end of the limiting rod 18 is fixedly connected to a hinge block 19, the upper surface of the splint 12 is fixedly installed with a hinge block 2 16, and a hinge plate 17 is hinged between the hinge block 19 and the hinge block 2 16.

[0057] A telescopic rod 2 is fixedly provided on the lower surface of the hinge block 19 , an end of the telescopic rod 2 is fixedly connected to an abutment block 21 , and a spring 20 is provided between the abutment block 21 and the hinge block 19 .

[0058] It is worth noting that Figure 2 and Figure 3As shown, after the four clamps 12 are in contact with the front, back, left and right sides of the concrete test block respectively, as the moving block 37 continues to move, when the spring 15 is compressed, the moving block 37 and the clamp 12 will also move relative to each other. In this process, under the hinged action of the hinged plate 17, the hinged block 2 16 and the abutment block 21 will move downward. When the abutment block 21 contacts the concrete test block below, the concrete test block can be further auxiliary fixed in the vertical direction. The two fixations have a better fixing effect, which can make the strength quality detection process of the concrete test block more stable and practical.

[0059] Embodiment 2, based on the above embodiment:

[0060] Further, the shielding component in the first embodiment is disclosed, the shielding component includes a rack row 1 31 fixedly connected to the side of the moving block 1 37, the inner wall of the control box 2 is fixedly connected to a support plate 32, the surface of the support plate 32 is connected to a rotating shaft 2 34 for fixed axis rotation, the surface of the rotating shaft 2 34 is fixedly connected to a gear 35 meshing with the rack row 1 31, the inner wall of the control box 2 is fixedly connected to a limit rod 2, and the surface of the limit rod 2 is slidably connected to a rack row 2 33 meshing with the gear 35;

[0061] The upper surface of the second rack row 33 is fixedly connected to the baffle plate 24, and the surface of the baffle plate 24 is fixedly connected with a protrusion 25. The surface of the detection platform 1 is provided with a through hole for the baffle plate 24 and the protrusion 25 to extend and slide; four arc-shaped baffles 8 are fixedly connected to the upper surface of the detection platform 1.

[0062] More specifically, when this embodiment is used, Figure 5 , Figure 6 and Figure 7 As shown, when the motor 41 is turned on, the moving column 36 and the moving block 1 37 are driven to move toward the center position of the test bench 1. The movement of the moving block 1 37 will also cause the rack row 1 31 to move synchronously. As the rack row 1 31 moves, the gear 35 is driven to rotate. As the gear 35 rotates, the rack row 2 33 is moved upward, so that the baffle plate 24 fixedly connected to the upper surface of the rack row 2 33 can be moved upward. After the four clamping plates 12 and the abutment blocks 21 complete the positioning and fixing of the concrete test block, the four baffle plates 24 will also be fully extended to the top of the test bench 1, and cooperate with the four arc-shaped baffle plates 8 above the test bench 1, that is, before the concrete test block is subjected to strength testing, it can be shielded in the four directions of front, back, left and right, thereby avoiding the problem that the broken concrete debris may splash and cause harm to the staff during the process of the pressing plate 6 descending to test the concrete test block, and the safety performance is higher.

[0063] It is worth noting that only when the moving block 37 moves to the center position of the testing platform 1 to position and fix the concrete test block on the testing platform 1, the four shielding plates 24 will be extended to the top of the testing platform 1 and will not block the space for placing the concrete test block on the testing platform 1. While being able to effectively block the splashing of debris, it also provides convenience for the staff to place the concrete test block on the testing platform 1.

[0064] Similarly, after the concrete test block is tested, the motor 41 is turned on to rotate in the opposite direction, so that the movable block 37 and the clamping plate 12 above it can release the fixation of the concrete test block. At this time, the four shielding plates 24 will also drop to the bottom of the test platform 1 again, thereby providing convenience for subsequent staff to clean up the crushed concrete test block debris on the test platform 1, which is more practical.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
