Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of concrete material testing equipment, and more specifically, to a concrete specimen molding device. Background Technology
[0002] Concrete test blocks are specimens formed by filling standard molds (such as cubes or cylinders) with concrete mixed on-site or in the laboratory according to national standards or engineering specifications. After being vibrated to compact the concrete, the surface is smoothed, and then cured for a certain period of time (usually 28 days) under specified temperature and humidity conditions. The core purpose is to determine the actual strength and durability of the concrete through testing, ensuring that the project quality meets the design requirements.
[0003] However, after the concrete test block is formed in the mold, the mold needs to be turned over and the test block needs to be tilted to remove it. This process is inefficient, difficult to operate, and tilting can easily cause damage to the edges and corners of the test block, affecting the overall forming quality of the test block and the accuracy of subsequent testing.
[0004] Therefore, there is an urgent need for a concrete specimen molding device that facilitates the demolding of specimens to solve the above problems. Utility Model Content
[0005] To address the shortcomings of existing methods, this invention provides a concrete test block molding device that features a modular structure for easy and quick assembly and disassembly, enabling rapid demolding of the test block while ensuring molding quality.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A concrete test block forming device includes a base plate, a forming mold, and isolation components. The forming mold is disposed on the base plate. A slot adapted to the bottom of the forming mold is formed on the upper surface of the base plate. The bottom of the forming mold is inserted into the slot. Multiple sets of positioning baffles are uniformly fixed at the outer edge of the slot. A buckle is fixed on the outer side of the positioning baffle. A self-locking buckle adapted to the buckle is installed on the outer side of the forming mold at the position corresponding to the buckle. Two sets of isolation components are longitudinally arranged inside the forming mold.
[0008] The isolation assembly includes a partition, an air nozzle, an inflation tube, a valve, and an airbag. There are two sets of partitions, and the airbag is located between the two sets of partitions. Its left and right sides are fixedly connected to the surface of the partition. The height of the partition is the same as the height of the molding die. An inflation tube is connected to the upper side of the airbag. A valve is installed on the inflation tube. An air nozzle for inflation is provided at the outer end of the inflation tube.
[0009] Furthermore, a first partition groove is provided on the base plate corresponding to the isolation component, and the bottom of the isolation component is inserted into the first partition groove. A second partition groove is provided on the front and rear sides of the inner wall of the molding mold corresponding to the isolation component, and the front and rear sides of the isolation component are inserted into the second partition groove.
[0010] Furthermore, each of the card slot, partition slot one, and partition slot two is provided with a layer of sealing gasket.
[0011] Furthermore, a U-shaped notch is provided at the upper edge of the front side of the molding die to match the inflation tube, and the notch is connected to the partition groove.
[0012] Furthermore, a transverse support rod is provided on the rear side of the forming mold, and a scraper is provided longitudinally on the upper side of the forming mold. The length of the scraper is greater than the longitudinal width of the forming mold, and the bottom surface of the scraper is in close contact with the upper end surface of the forming mold. The rear end of the scraper is slidably connected to the support rod through a slide block.
[0013] Furthermore, handles are fixedly provided on both the left and right sides of the molding die.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This utility model adopts a split structure design, and the base plate, molding mold and isolation components can be disassembled. The molding device can be disassembled after the test block is molded, making it convenient to take out the molded test block. There is no need to invert the device for demolding, which realizes the rapid demolding of the test block. At the same time, the test block is intact and undamaged, ensuring the molding quality of the test block.
[0016] 2. The device of this utility model comes with a leveling component. The set scraper facilitates the leveling operation of concrete test blocks. It can level the surface of the concrete test block after it is poured, so that the surface remains flat. At the same time, the support rod provides a guide track for the sliding of the scraper, ensuring that the scraper moves accurately along the preset transverse path, thus ensuring the standardization and consistency of the operation.
[0017] 3. This utility model can divide the interior of the molding mold into multiple spaces through the isolation components, and can simultaneously cast multiple concrete test blocks, thus improving the testing efficiency. At the same time, the partitions are connected by air bladders. After the concrete test block is formed, the air bladders are deflated through the inflation tube, reducing the volume of the air bladders. The tension of the air bladders pulls the two sets of partitions closer to the air bladders, thereby separating the concrete test block from the inner wall of the partitions, thus achieving rapid demolding.

Detailed Implementation
[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0028] Example:
[0029] like Figures 1 to 8 As shown, a concrete test block forming device includes a base plate 1, a forming mold 2 and an isolation component 4. The forming mold 2 is set on the base plate 1. The upper surface of the base plate 1 is provided with a slot 12 that is adapted to the bottom of the forming mold 2. The bottom of the forming mold 2 is inserted into the slot 12. Multiple sets of positioning baffles 8 are evenly fixed at the outer edge of the slot 12. A buckle 7 is fixed on the outer side of the positioning baffle 8. A self-locking buckle 6 that is adapted to the buckle 7 is installed on the outer side of the forming mold 2 at the position corresponding to the buckle 7. Two sets of isolation components 4 are arranged longitudinally inside the forming mold 2.
[0030] The isolation assembly 4 includes partitions 41, air nozzles 42, inflation pipes 43, valves 44, and airbags 45. There are two sets of partitions 41, and the airbags 45 are located between the two sets of partitions 41. The left and right sides of the airbags 45 are fixedly connected to the surface of the partitions 41. The height of the partitions 41 is the same as the height of the molding mold 2. The upper side of the airbags 45 is connected to the inflation pipes 43, and the valves 44 are installed on the inflation pipes 43. The outer end of the inflation pipes 43 is provided with air nozzles 42 for inflation. The isolation assembly 4 can divide the interior of the molding mold 2 into multiple spaces, and multiple concrete test blocks can be poured at the same time, which improves the testing efficiency. At the same time, the partitions 41 are connected by the airbags 45. After the concrete test block is formed, the airbags 45 are deflated through the inflation pipes 43, which reduces the volume of the airbags 45. The tension of the airbags 45 drives the two sets of partitions 41 to move closer to the airbags 45, thereby separating the concrete test block from the inner wall of the partitions 41, thus achieving rapid demolding. This design solves the problem that in the existing technology, after the concrete test block is formed in the mold, the mold needs to be turned over and the test block tilted to remove it. This process is inefficient, difficult to operate, and tilting can easily cause damage to the edges and corners of the test block, affecting the overall forming quality of the test block and the accuracy of subsequent testing.
[0031] In this embodiment, a first groove 13 is provided on the base plate 1 at a position corresponding to the isolation component 4, and the bottom of the isolation component 4 is inserted into the first groove 13. A second groove 14 is provided on the front and rear sides of the inner wall of the molding mold 2 at a position corresponding to the isolation component 4, and the front and rear sides of the isolation component 4 are inserted into the second groove 14. This design, through the first groove 13 and the second groove 14, facilitates the rapid positioning and assembly of the isolation component 4, and allows for precise positioning of the isolation component 4 from multiple directions, ensuring the stability of the isolation component 4.
[0032] In this embodiment, a sealing gasket 11 is provided in each of the slot 12, partition 13, and partition 2 14. During the concrete pouring process, the grout is fluid. If there are gaps between the slot 12, partition 13, and partition 2 14 and the molding mold 2 and the isolation component 4, the grout will leak through these gaps. The sealing gasket 11 is made of flexible, compressible rubber or silicone and can closely fit the contact surface, fill any possible tiny gaps, form a reliable sealing barrier, and ensure the sealing of the connection.
[0033] In this embodiment, a U-shaped notch 15 adapted to the inflation tube 43 is provided at the upper edge of the front side of the molding mold 2. The notch 15 is connected to the partition groove 14. The U-shaped notch 15 is adapted to the shape of the inflation tube 43, providing a dedicated space for the inflation tube 43, so that the inflation tube 43 can be neatly arranged along the upper edge of the front side of the molding mold 2 along the notch 15, avoiding interference between the inflation tube 43 and other components.
[0034] In this embodiment, a transverse support rod 9 is provided on the rear side of the molding mold 2, and a scraper 5 is provided longitudinally on the upper side of the molding mold 2. The length of the scraper 5 is greater than the longitudinal width of the molding mold 2, and the bottom surface of the scraper 5 is in close contact with the upper end surface of the molding mold 2. The rear end of the scraper 5 is slidably connected to the support rod 9 through a slide block 10. The scraper 5 facilitates the leveling operation of the concrete test block, and can level the surface of the concrete test block after pouring, keeping the surface flat. At the same time, the support rod 9 provides a guide track for the sliding of the scraper 5, ensuring that the scraper 5 moves accurately along the preset transverse path, ensuring the standardization and consistency of the operation.
[0035] In this embodiment, handles 3 are fixed on both the left and right sides of the molding mold 2. The handles 3 facilitate the removal of the molding mold 2 from the base plate 1 for demolding. After the concrete test block is molded, demolding is required. The operator can simultaneously grasp the handles 3 on both sides and apply uniform force to lift or flip the molding mold 2 from the concrete test block, achieving smooth demolding. Furthermore, the handles 3 also facilitate the handling and movement of the device.
[0036] The working principle of this concrete test block molding device:
[0037] In actual use, align the bottom of the molding mold 2 with the slot 12 on the base plate 1, and insert the bottom of the molding mold 2 into the slot 12. Use the slot 12 and the positioning baffle 8 to initially position the molding mold 2. Then, fasten the self-locking buckle 6 on the outer side of the molding mold 2 with the buckle 7 on the outer side of the positioning baffle 8 to ensure that the molding mold 2 is firmly fixed on the base plate 1.
[0038] Then, insert the bottom of the isolation component 4 into the corresponding slot 13 on the base plate 1, and simultaneously insert the front and rear sides of the isolation component 4 into the slots 14 on the front and rear sides of the inner wall of the molding mold 2. This completes the installation of the isolation component 4. Insert the inflation tube 43 into the U-shaped notch 15 on the upper edge of the front side of the molding mold 2 to prevent interference between the inflation tube 43 and other components. Connect the air nozzle 42 to an external air pump, open the valve 44, and inflate the airbag 45 through the inflation tube 43. After the airbag 45 inflates, it pushes the two sets of partitions 41 to the sides, ensuring that the edges of the partitions 41 are tightly fitted into the slots 13 and 14.
[0039] Then, the prepared concrete is slowly poured into the molding mold 2. Pouring is stopped when the concrete level is slightly above the top surface of the molding mold 2. The operator holds the scraper 5 and pushes it laterally along the support rod 9 on the rear side of the molding mold 2, allowing the scraper 5 to slide from one end of the molding mold 2 to the other. During this sliding process, the scraper 5 removes excess concrete, making the concrete surface smooth.
[0040] After the leveling operation is completed, the concrete inside the molding mold 2 is cured. Once the concrete test block has reached the specified curing time and achieved a certain strength, the demolding operation is performed. First, open the valve 44 on the inflation pipe 43 to deflate the airbag 45, reducing its volume. The tension of the airbag 45 pulls the two sets of partitions 41 towards the airbag 45, thus separating the concrete test block from the inner wall of the partitions 41. Then, open the self-locking latch 6 to separate it from the latch seat 7. Next, simultaneously grasp the handles 3 on both sides of the molding mold 2 with both hands, applying a uniform force to slowly lift the molding mold 2 from the concrete test block. During the lifting process, continuously shake the molding mold 2; under the action of gravity, the test block smoothly separates from the inner wall of the molding mold 2, achieving demolding. Then, remove the test block from the base plate 1.
[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
