Technical Field

[0001] This utility model relates to the field of concrete technology, specifically to a testing device for building concrete. Background Technology

[0002] Concrete (an engineering composite material formed by mixing cementitious materials such as cement, aggregates, sand, and stone) and water in a certain proportion and then hardening it) is widely used in civil engineering, with a global annual production of over 4 billion tons.

[0003] Publication number CN220542670U discloses a concrete strength testing device. By incorporating a hydraulic cylinder, sliding plate, support rod, pressure plate, pressure sensor, air cylinder, clamping plate, insertion rod, base plate, motor, screw, clamping plate, connecting rod, and rollers, it facilitates the movement of concrete by the user while improving work efficiency. However, this patent still has the following problems in practical use:

[0004] The inconvenience of restricting space around the concrete means that during concrete testing, broken concrete blocks are crushed into multiple small pieces, resulting in a wide distribution of crushed concrete blocks that may even fall directly into the equipment, making subsequent cleanup difficult and affecting work efficiency.

[0005] A testing device for building concrete is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a testing device for building concrete, in order to solve the problem mentioned in the background art that it is currently inconvenient to restrict the space around the concrete. This results in the crushed concrete blocks being crushed into multiple small pieces during concrete testing, leading to a wide distribution of crushed concrete blocks, which may even fall directly into the device, making subsequent cleaning inconvenient and affecting work efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a testing device for building concrete, comprising a base plate and a placement plate installed on top of the base plate;

[0008] A fixing plate is fixedly connected to the top of the base plate, and a mounting block is fixedly connected to the front of the fixing plate. A hydraulic rod is fixedly connected inside the mounting block, and a fixing block is fixedly connected to the bottom of the hydraulic rod.

[0009] Also includes:

[0010] The front of the fixed plate is provided with an adjustment component, which includes a connecting block. The connecting block is fixed to one side of the fixed block, and a slot is opened inside the connecting block. A limit post is fixedly connected inside the slot, and a slide rod is slidably connected to the outside of the limit post.

[0011] Among them, a connecting piece is fixedly connected to one side of the slide rod, and a first spring is fixedly connected between the connecting piece and the connecting block, and a pressing block is fixedly connected to the other side of the slide rod.

[0012] The extrusion block has a movable piece on its outside and a groove inside the movable piece, allowing the extrusion block to slide inside the groove.

[0013] Preferably, a limiting piece is fixedly connected to the front of the fixing plate, and a block is fixedly connected to the top of the limiting piece, and a second spring is fixedly connected to one side of the block.

[0014] Preferably, a movable block is fixedly connected to one side of the second spring, and the movable block is fixedly connected to the movable piece.

[0015] Preferably, the limiting piece is symmetrically fixed with support bars on its upper and lower sides, and the support bars are slidably connected to the outside of the limiting piece with a first protective shell. The first protective shell is located on one side of the limiting piece, and a second protective shell is fixedly connected to the other side of the top of the limiting piece.

[0016] Preferably, the connecting block is L-shaped.

[0017] Preferably, the bottom of the fixing block is provided with a disassembly component, the disassembly component includes a positioning block, and the bottom of the positioning block is slidably connected to a sliding block, and the bottom of the sliding block is fixedly connected to a stamping block.

[0018] Preferably, a mounting plate is fixedly connected to one side of the positioning block, and a fastening bolt is threadedly connected between the mounting plate and the pressure block.

[0019] Compared with the prior art, the beneficial effects of this utility model are: this testing device for building concrete can confine the concrete within a certain space before testing its compression, thereby preventing the concrete from scattering into fragments when crushed, which would be inconvenient for cleaning. The specific details are as follows:

[0020] 1. When concrete hardness testing is required, the concrete can be placed on top of the placement plate. Then, the hydraulic rod is activated, which lowers the positions of the fixing block and the pressure block. As the fixing block descends, the connecting block also descends, causing the sliding rod to descend. The first spring's force is greater than the second spring's force, causing the moving plate to move to the left. The moving plate then moves the moving block to the left and stretches the second spring until the second protective shell connects, covering the concrete from all sides. This prevents the sliding rod from moving with the fixing block, compresses the first spring to accommodate the descent of the connecting block, and lowers the pressure block until it engages with the concrete for pressure testing. This creates a protective space around the concrete before pressure testing, preventing crushed concrete pieces from scattering and becoming difficult to clean.

[0021] 2. When it is necessary to disassemble and replace the pressure block, the fastening bolts can be unscrewed to release the limit on the mounting plate. Then, the pressure block can be pulled down to disengage it from the inside of the positioning block. The new pressure block can then be disassembled and inserted into the inside of the positioning block. Finally, it can be fixed again with the fastening bolts to achieve the disassembly and replacement of the pressure block. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 The present invention provides the following technical solution:

[0031] A testing device for building concrete includes a base plate 1 and a placement plate 2 mounted on top of the base plate 1. A fixing plate 3 is fixedly connected to the top of the base plate 1, and a mounting block 301 is fixedly connected to the front of the fixing plate 3. A hydraulic rod 302 is fixedly connected inside the mounting block 301, and a fixing block 303 is fixedly connected to the bottom of the hydraulic rod 302. An adjustment assembly 4 is provided on the front of the fixing plate 3. The adjustment assembly 4 includes a connecting block 401, which is fixed to one side of the fixing block 303. A slot 40 is formed inside the connecting block 401. 2. A limiting post 403 is fixedly connected inside the slot 402, and a sliding rod 404 is slidably connected to the outside of the limiting post 403; a connecting piece 405 is fixedly connected to one side of the reverse side of the sliding rod 404, and a first spring 406 is fixedly connected between the connecting piece 405 and the connecting block 401; and a pressing block 407 is fixedly connected to the other side of the reverse side of the sliding rod 404; a moving piece 408 is provided outside the pressing block 407, and a sliding groove 409 is opened inside the moving piece 408, and the pressing block 407 can slide inside the sliding groove 409.

[0032] A limiting piece 410 is fixedly connected to the front of the fixed plate 3, and a block 411 is fixedly connected to the top of the limiting piece 410. A second spring 412 is fixedly connected to one side of the block 411, and a moving block 413 is fixedly connected to one side of the second spring 412. The moving block 413 is fixedly connected to the moving piece 408. Support strips 4131 are symmetrically fixed to the upper and lower parts of the limiting piece 410. Figures 1-2 , Figures 4-5 As shown, when concrete hardness testing is required, the concrete can be placed on top of the placement plate 2, and then the hydraulic rod 302 is activated, which causes the fixed block 303 and the pressing block 503 to descend. At the same time, when the fixed block 303 descends, it will cause the connecting block 401 to descend, which in turn causes the sliding rod 404 to descend. Furthermore, the elastic force of the first spring 406 is greater than that of the second spring 412. Therefore, when the sliding rod 404 descends, the first spring 406 will not be compressed, and the position of the pressing block 407 will also descend.

[0033] Then, the pressing block 407 will press the moving piece 408, causing the moving piece 408 to move to the left. Then, the moving piece 408 will drive the moving block 413 to move to the left and stretch the second spring 412. Next, since the moving block 413 is fixed to the first protective shell 414, the moving block 413 will drive the first protective shell 414 to approach the second protective shell 415 until it docks with the second protective shell 415, while covering the concrete around.

[0034] Furthermore, the size of the concrete to be tested must be smaller than the width of the placement plate 2. Since the position of the first protective shell 414 can no longer be moved, the position of the sliding rod 404 will not move with the movement of the fixed block 303. When the fixed block 303 continues to descend, the sliding rod 404 will continue to descend, but the sliding rod 404 will not descend further. At this time, the first spring 406 will be compressed to adapt to the descent of the connecting block 401. At this time, the position of the stamping block 503 will also descend.

[0035] Until a pressure test is conducted on the concrete, a protective space is formed around the concrete before the pressure test, thus preventing the crushed concrete blocks from scattering everywhere and making cleaning difficult. The support strip 4131 and the limiting plate 410 are slidably connected to the outside of the first protective shell 414, which is located on one side of the limiting plate 410. The other side of the top of the limiting plate 410 is fixedly connected to the second protective shell 415, and the connecting block 401 is L-shaped.

[0036] The bottom of the fixing block 303 is provided with a disassembly assembly 5, which includes a positioning block 501. A sliding block 502 is slidably connected to the bottom of the positioning block 501, and a punching block 503 is fixedly connected to the bottom of the sliding block 502. Furthermore, a pressure sensor can be installed on the punching block 503 to facilitate recording the pressure borne by the concrete. An mounting plate 504 is fixedly connected to one side of the positioning block 501. Figure 3 As shown, when it is necessary to disassemble and replace the pressure block 503, the fastening bolt 505 can be unscrewed to release the restriction on the mounting plate 504.

[0037] Then, the stamping block 503 can be pulled down to disengage it from the interior of the positioning block 501. A new stamping block 503 can then be disassembled and inserted into the interior of the positioning block 501. Finally, it can be re-fixed by the fastening bolt 505, thereby realizing the disassembly and replacement of the stamping block 503. The mounting plate 504 and the pressure block 503 are threadedly connected by the fastening bolt 505.

[0038] Working principle: Before using this testing device for building concrete, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 6 As shown, firstly, when it is necessary to test the hardness of concrete, the concrete can be placed on top of the placement plate 2, and then the hydraulic rod 302 is activated, which causes the fixed block 303 and the pressing block 503 to descend. At the same time, when the fixed block 303 descends, it will cause the connecting block 401 to descend, which in turn causes the sliding rod 404 to descend. Secondly, the elastic force of the first spring 406 is greater than that of the second spring 412. Therefore, when the sliding rod 404 descends, the first spring 406 will not be compressed, and the position of the pressing block 407 will also descend. Then the pressing block 407 will press the moving plate 408, causing the moving plate 408 to move to the left. Then the moving plate 408 will drive the moving block 413 to move to the left and stretch the second spring 412.

[0039] Secondly, since the moving block 413 is fixed to the first protective shell 414, the moving block 413 will drive the first protective shell 414 closer to the second protective shell 415 until it docks with the second protective shell 415, while covering the concrete around it. The size of the concrete to be tested must be smaller than the width of the placement plate 2. At this time, since the position of the first protective shell 414 can no longer be moved, the position of the sliding rod 404 will not move with the fixed block 303. At this time, the fixed block 303 continues to descend, and the sliding rod 404 will not descend further. At this time, the first spring 406 will be compressed to adapt to the descent of the connecting block 401. At this time, the position of the punching block 503 will also descend until it generates pressure test with the concrete. This achieves the formation of a protective space around the concrete before the concrete pressure test, thereby preventing the crushed concrete blocks from scattering everywhere and making it inconvenient to clean.

[0040] When it is necessary to disassemble and replace the pressure block 503, the fastening bolt 505 can be unscrewed to release the limit on the mounting plate 504. Then, the stamping block 503 can be pulled down to disengage it from the interior of the positioning block 501. Then, the new stamping block 503 can be disassembled and inserted into the interior of the positioning block 501. Finally, it can be fixed again by the fastening bolt 505, thereby realizing the disassembly and replacement of the stamping block 503.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
