Description

Technical Field

[0001] The utility model relates to the technical field of concrete testing, in particular to a sample preparation device for concrete testing. Background Art

[0002] The preparation of concrete test blocks is a key link in ensuring the accuracy of concrete strength tests. The process begins with sufficient preparation, including cleaning and checking the accuracy of the test mold size and angles, and preparing the necessary tools and materials. Subsequently, the release agent is evenly applied to the inner wall of the test mold to facilitate demoulding and protect the mold. Concrete needs to be sampled from representative locations and fully mixed to ensure uniformity. When filling the mold, the concrete is loaded in two layers and compacted layer by layer to ensure that it is dense and free of bubbles. After compaction, the surface is polished to prevent dents. After molding, the test block needs to be covered to reduce moisture evaporation and sent to a standard curing room for curing under precisely controlled conditions after hardening. Finally, key information needs to be marked on the surface of the test block, and various parameters in the production process need to be recorded to ensure the quality of the test block and the accuracy of the test results. The entire production process must strictly comply with the specifications and operating procedures to ensure the representativeness of the test block and the effectiveness of the test.

[0003] However, existing concrete testing equipment, known as test molds, has exposed some significant drawbacks during actual use. One of these is the inherent limitations of its cubic structure. Specifically, due to its overall cubic design, all of its inner walls are vertical. This design presents significant inconvenience when applying release agent. The release agent needs to be evenly and thinly applied to the inner walls to ensure smooth demolding of the specimen without affecting the test results. However, the right angles and edges of the cubic test mold make it difficult to achieve ideal application conditions. Especially in corners and joints, it is often difficult to ensure uniform coverage of the release agent. This not only increases the complexity of the operation but also may affect the demolding effect. In addition, after the specimen is tested and demolded, cleaning the inner walls of the test mold is also challenging. The inner walls of the cubic test mold are perpendicular to each other, which easily forms hard-to-reach corners and crevices. After concrete residue accumulates in these areas, it is difficult to completely remove them by conventional means. This not only increases the difficulty and time cost of cleaning, but also may affect the quality of subsequent test specimens due to incomplete cleaning, forming a vicious cycle.

[0043] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0044] Combine Figure 1-Figure 5 As shown, the present invention is a concrete testing sample preparation device, which is characterized by comprising:

[0045] A bottom plate 1, one side surface of which is in contact with the concrete mixture;

[0046] Connectors 2 are provided on the side walls of the bottom plate 1, and are at least four in number and are symmetrically distributed around the center of the bottom plate 1;

[0047] The side panels 3 are provided on the connecting member 2 and are detachably connected to the bottom plate 1 via the connecting member 2. There are four side panels 3 and they are symmetrically distributed around the center of the bottom plate 1. The four side panels 3 and the bottom plate 1 together form a receiving area, and the receiving area can be filled with a test concrete mixture sample.

[0048] The fixing member 4 is provided on the side panels 3 and is used to fix and limit two adjacent side panels 3 to ensure that a test mold is formed between the bottom panel 1 and the four side panels 3 .

[0049] The equipment is mainly composed of a base plate 1, connectors 2, side panels 3 and fixing members 4. First, the base plate 1 serves as the bottom foundation of the test mold, and one side surface of the base plate is in direct contact with the concrete mixture to ensure that the mixture can be evenly distributed and tightly fits the base plate surface during the molding process. Then, the connectors 2 are carefully arranged on the side walls of the base plate 1. These connectors are not only sufficient in number but also symmetrically distributed according to the center of the base plate 1 to ensure the stability and balance of the entire test mold structure. The design of the connectors 2 enables the side panels 3 to be firmly connected to them while maintaining the flexibility of the test mold. The side panels 3 serve as the side wall parts of the test mold, and there are four of them. They are also symmetrically distributed according to the center of the base plate 1. These side panels 3 are detachably connected to the base plate 1 through the connectors 2. This design makes the test mold easier to assemble. The assembly and disassembly process is more convenient and quick. The four side panels 3 and the bottom plate 1 together constitute a closed accommodating area, into which the concrete mixture sample to be tested can be loaded. In order to further enhance the structural strength and stability of the test mold, the fixing member 4 is cleverly arranged on the side panel 3 and interconnected with the adjacent side panels 3. The main function of the fixing member 4 is to fix and limit the two adjacent side panels 3 to ensure that the bottom plate 1 and the four side panels 3 can fit closely together during the concrete mixture filling, tamping and molding process to form a complete and stable test mold. In summary, the concrete test sample preparation equipment realizes the effective accommodation and molding of the concrete mixture sample through the coordinated work of the bottom plate 1, the connecting piece 2, the side panel 3 and the fixing member 4, providing accurate and reliable test block samples for subsequent concrete strength tests.

[0050] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 、 Figure 2 As shown; the connecting member 2 includes:

[0051] The connecting tubes 21 are fixedly mounted on the side walls of the bottom plate 1 , and are divided into four groups, at least four in number, and are respectively arranged on the four side walls of the bottom plate 1 ;

[0052] The latches 22 are intermittently connected to the inner side of the connecting tube 21 , and the number and distribution of the latches 22 match those of the connecting tube 21 ; and

[0053] The fixing part 23, one side surface of which is fixedly connected to one end of the pin 22, and the other side surface is fixedly connected to the surface of the side panel 3, wherein the number of the fixing parts 23 corresponds to the number of the pins 22. The connecting tube 21 is a basic component for fixed installation and is firmly installed on the side wall of the bottom plate 1. There are no less than four of them, and they are equally divided into four groups, each of which is arranged on a side wall of the bottom plate 1. Such a layout ensures the symmetry and stability of the test mold structure. The design of the connecting tube 21 allows the pin 22 to be connected with a gap inside it, providing a reliable support and positioning point for the installation of the side panel 3. Next, the pin 22 is a movable component in the connector 2, and its number and distribution position are adapted to the connecting tube 21. The pin 22 can be flexibly inserted into and fixed on the inner side of the connecting tube 21, and the gap connection between them realizes the preliminary connection between the side panel 3 and the bottom plate 1. This design not only makes the connection process more convenient, but also allows disassembly and adjustment when necessary. Finally, the fixing part 23 serves as the key fixing component in the connecting part 2. One side surface of the fixing part is fixedly connected to one end of the pin 22, and the other end is fixedly connected to the surface of the side panel 3. The number of the fixing parts 23 corresponds to the number of the pins 22, ensuring that each pin 22 can form a stable connection with the side panel 3 through the fixing part 23. Under the action of the fixing part 23, the side panel 3 is tightly locked on the bottom plate 1, and together with the bottom plate 1, it constitutes a complete trial mold structure.

[0054] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 、 Figure 3 As shown; the fixing member 4 includes:

[0055] There are four mounting plates 41 connected to the two side walls of two of the side plates 3 by bolts, wherein the mounting plates 41 are installed on the left and right side walls of the two side plates 3;

[0056] The limiting seat 42 is fixedly mounted on the surface of the side of the mounting plate 41 away from the side plate 3, and its number and distribution position are adapted to the mounting plate 41;

[0057] Four sliding seats 43 are connected to the surfaces of the other two side panels 3 by bolts, and the sliding seats 43 are installed on the opposite sides of the other two side panels 3; and

[0058] The limiting plug-in 44 is slidably connected to the side surface of the sliding seat 43 away from the side panel 3, wherein the number and distribution position of the limiting plug-in 44 are adapted to the sliding seat 43, and the limiting plug-in 44 can be inserted into the inner side of the adjacent limiting seat 42 to fix the two adjacent side panels 3. The mounting plate 41 serves as the basic component of the fixing member 4, and there are four of them, which are respectively connected to the left and right side walls of the two side panels 3 at relative positions in the test mold by bolts. This layout ensures that the fixing member 4 can be evenly distributed around the test mold, providing a stable support point for subsequent fixing operations. Then, the limiting seat 42 is fixedly installed on the side surface of the mounting plate 41 away from the side panel 3, and its number and distribution position are adapted to the mounting plate 41. The design of the limiting seat 42 is to cooperate with the limiting plug-in 44 to achieve relative The adjacent side panels 3 are fixed and limited. Then, the sliding seat 43 is another key component, and its number is also four. It is connected to the surface of the other two side panels 3 in the test mold by bolts, and the two side panels 3 are installed with sliding seats 43 on the opposite sides. The design of the sliding seat 43 allows the limiting plug-in 44 to be slidably connected thereon, thereby realizing the fixation between the adjacent side panels 3. Finally, the limiting plug-in 44 is a movable component in the fixed component 4, and its number and distribution position are adapted to the sliding seat 43. The limiting plug-in 44 can be slidably connected to the side surface of the sliding seat 43 away from the side panel 3, and can be inserted into the inner side of the adjacent limiting seat 42. When the limiting plug-in 44 is fully inserted into the limiting seat 42, the two adjacent side panels 3 are firmly fixed together, thereby ensuring the overall stability and structural strength of the test mold.

[0059] In a preferred embodiment, the present invention can be further configured as follows: Figure 3 、 Figure 4As shown; a jack seat 5 is also fixedly installed on the surface of the limiting plug-in 44, wherein a limiting hole 6 is processed on the surface of the jack seat 5, and a magnet 7 corresponding to the position of the limiting hole 6 is fixedly installed on the surface of the limiting seat 42, and a T-shaped limiting pin 8 is connected to the gap in the limiting hole 6, wherein the T-shaped limiting pin 8 is made of metal material, and one end of the T-shaped limiting pin 8 can be adsorbed with the magnet 7. On the basis of the fixed component 4, a jack seat 5 is also fixedly installed on the surface of the limiting plug-in 44, and the jack seat 5 is an additional component, and a limiting hole 6 is processed on its surface. The position and number of these limiting holes 6 correspond to the magnet 7 fixedly installed on the surface of the limiting seat 42. This design makes it possible for the limiting plug-in 44 to cooperate with the limiting seat 42. When the jack seat 5 and the magnet 7 are connected, the jack seat 5 and the magnet 7 can be precisely aligned. The T-shaped limit pin 8 is a key component, which is made of metal material and has sufficient strength and hardness to ensure a stable fixing effect. The T-shaped limit pin 8 is inserted into the limit hole 6 of the jack seat 5 through a gap connection. This connection method allows a certain amount of fine-tuning space and ensures the stability of the connection. What is more important is that when the T-shaped limit pin 8 is inserted into the limit hole 6 and approaches the magnet 7, due to its metal material characteristics, one end of the T-shaped limit pin 8 will be adsorbed with the magnet 7. This magnetic adsorption effect not only enhances the connection strength between the limit plug-in 44 and the limit seat 42, but also ensures that the limit plug-in 44 is not easy to fall off or loosen when subjected to external force.

[0060] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 As shown; a sealing rubber pad 9 is fixedly installed at the end edge of the side panel 3 and is flush with the height of the side panel 3. When two adjacent side panels 3 are connected to each other, the sealing rubber pad 9 can be squeezed to achieve leakage prevention at the joint of the test mold. At the end edge of the side panel 3, that is, the edge where the side panels 3 are connected to each other to form the enclosure structure of the test mold, a sealing rubber pad 9 is fixedly installed and is flush with the height of the side panel 3. The sealing rubber pad 9 is a material with good elasticity and sealing, and is designed and installed at the joint position of the side panel 3 to ensure that the test mold can form an effective sealing barrier during the assembly process. When two adjacent side panels When the two plates 3 are connected by fixing members 4 or other connection methods, they will squeeze the sealing rubber pads 9 located at the edges of their respective ends. This squeezing action causes the sealing rubber pads 9 to deform and fit tightly to the butt joint surfaces of the two side plates 3, thereby filling any possible small gaps or unevenness. Through the elastic deformation and tight fit of the sealing rubber pads 9, the leak-proof performance of the test mold joint is significantly improved. Even when the concrete mixture is loaded into the test mold and subjected to operations such as tamping, the mixture is unlikely to leak out through the small gaps at the joint, thereby ensuring the accuracy and reliability of the test.

[0061] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 、 Figure 5 As shown; a handrail 10 is fixedly installed on the end portion of one side panel 3 away from the bottom plate 1, and a clip 11 is detachably connected to the handrail 10, and a corrugated metal hose 12 is fixedly installed on the clip 11, and a storage component 13 for storing test concrete sample information is provided on the other end of the corrugated metal hose 12. A handrail 10 is fixedly installed on the end portion of one side panel 3 away from the bottom plate 1. The design of the handrail 10 not only provides a position for the operator to hold and move the test mold, but also serves as a support point for an additional functional component. A clip 11 is detachably connected to the handrail 10. This detachable connection method allows the clip 11 to be easily installed or removed as needed, which increases the flexibility of use. The design of the clip 11 ensures that it can be firmly fixed on the handrail 10 to support the subsequently connected components. A corrugated metal hose 12 is further fixedly installed on the clip 11. 12 is a flexible and durable material that can bend and maintain a certain shape to adapt to different usage scenarios. One end of it is connected to the clip 11 to ensure the stability of the connection; the other end is provided with a storage component 13 for storing the test concrete sample information. The storage component 13 is the core part of this design. It can be a box with a label or record card, a clip or other form of container for storing information related to the current test concrete sample, such as the sample number, test date, concrete mix ratio, etc. This information is crucial for subsequent test records, data analysis and result comparison. When the operator needs to conduct a concrete test, the storage component 13 containing the sample information can be fixed to the handrail 10 through the corrugated metal hose 12 and the clip 11. In this way, no matter where the test mold is moved for testing, the storage component 13 will move with it, ensuring that the sample information is portable and easy to access.

[0062] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 、 Figure 5 Storage assembly 13 includes:

[0063] The connecting arm 131 is fixedly mounted on the outside of the corrugated metal hose 12, and one end of the connecting arm 131 is machined with a notch;

[0064] The cover 132 is fixedly mounted on one side surface of the connecting arm 131;

[0066] A screw rod 134 is hinged to the storage box 133 and can rotate relative to the storage box 133. The screw rod 134 can be located inside the notch; and

[0067] The hand-tightening nut 135 is threadedly connected to the outer side of the screw rod 134 and contacts one side surface of the connecting arm 131. The storage assembly 13 is mainly composed of the connecting arm 131, the cover body 132, the storage box 133, the screw rod 134 and the hand-tightening nut 135. These components cooperate with each other to achieve the storage, protection and convenient access of the sample information. First, the connecting arm 131 serves as a support and connecting component of the storage assembly 13 and is fixedly installed on the outer side of the corrugated metal hose 12. A notch is processed at one end thereof. The notch is designed to cooperate with the screw rod 134 to achieve the locking or release of the storage box 133. The cover body 132 is fixedly installed on one side surface of the connecting arm 131 and adapts to the storage box 133. A closed placement area is formed between the cover body 132 and the storage box 133 for storing relevant information of the test concrete sample, such as the sample number, test date, concrete mix ratio, etc. The storage box 133 is hinged. The screw 134 is hinged to the storage box 133 and can rotate relative to it. When the storage box 133 is closed, the screw 134 can be rotated to the inside of the notch of the connecting arm 131 and locked with the hand nut 135. This locking mechanism ensures that the storage box 133 will not be accidentally opened during transportation or testing, thereby protecting the safety of the sample information. The hand nut 135 is threadedly connected to the outer side of the screw 134 and contacts one side surface of the connecting arm 131. By rotating the hand nut 135, the degree of thread engagement between it and the screw 134 can be adjusted, thereby controlling the locking or release of the storage box 133. This design makes the locking and releasing operations simple and quick.

[0068] In a preferred embodiment, the present invention can be further configured as follows: Figure 1As shown; a transparent glass cover 14 is embedded on the surface of the storage box 133 away from the cover 132. The storage box 133 is a key component for storing the test concrete sample information. Its internal space is used to place related record cards, labels or other forms of information carriers. In order to facilitate the operator to quickly view the sample information without opening the storage box 133, the designer embedded a transparent glass cover 14 on the surface of the storage box 133 away from the cover 132. The transparent glass cover 14 is made of transparent materials, such as glass, acrylic, etc., with good light transmittance and certain impact resistance. It is tightly embedded in the side surface of the storage box 133. It is tightly integrated with the border or frame of the storage box 133 to form a closed but visible observation window. When the operator needs to put the sample information into the storage box 133, they can open the cover 132, place the information carrier in the placement area inside the storage box 133, and then close the cover 132 to ensure the safety of the information. Afterwards, the operator does not need to open the storage box 133 again, but can clearly view the sample information in the storage box 133 through the transparent glass cover 14. The design of the transparent glass cover 14 not only improves the convenience of information viewing, but also protects the information carrier inside the storage box 133 from contamination or damage from the external environment.

[0069] The specific working principle of the concrete testing sample preparation equipment of the utility model is as follows:

[0070] Apply release agent evenly on the side panels 3 and place the bottom panel 1 on a stable workbench. One side of the bottom panel 1 is designed to be in contact with the concrete mixture. The four side panels 3 are respectively mounted on the four side walls of the bottom panel 1 through the combination of the connecting tube 21 and the latch 22 in the connector 2, ensuring that they are symmetrically distributed and firmly connected. Each side panel 3 is fixed with the fixing member 23 and the latch 22 to form a preliminary test mold frame. The test mold is further reinforced with the fixing member 4. The limit seat 42 is installed on the mounting plate 41, and the sliding seat 43 is installed on the two opposite side panels 3. , slide the limiting plug 44 into the sliding seat 43, and insert it into the limiting seat 42 on the adjacent side panel 3 to achieve fixation and limiting between the side panels 3. At this time, the fixing effect can be further enhanced by the adsorption effect of the T-shaped limiting pin 8 and the magnet 7 to ensure the stability of the test mold structure. At the end edge of the side panel 3, a sealing rubber pad 9 flush with the height of the side panel 3 has been installed. When the two adjacent side panels 3 are tightly connected, the sealing rubber pad 9 is squeezed, thereby achieving leak-proofing at the test mold joint and ensuring that the concrete mixture will not seep out from the joint.

[0071] After confirming that the test mold is stable and sealed, pour the concrete mixture into the containing area formed by the bottom plate 1 and the four side plates 3. At this time, the concrete mixture will be confined in the test mold for subsequent molding and curing. When removing the mold, the T-shaped limit pin 8 can be removed and the limit plug 44 can be disconnected from the inner side of the limit seat 42. Then, the side plates 3 can be removed to facilitate subsequent demoulding.

[0072] During the sample preparation process, the storage assembly 13 is used to manage the information of the test concrete sample. The storage assembly 13 is fixed to the handrail 10 through the corrugated metal hose 12 and the clamp 11, so that it can be moved together with the test mold. The connecting arm 131 in the storage assembly 13 is fixedly installed on the outside of the corrugated metal hose 12. A cover 132 and a storage box 133 are provided on the storage assembly 13. The information of the test concrete sample, such as the sample number and test date, is placed in the storage box 133 and closed by the cover 132 to protect the information. If the information needs to be viewed, it can be directly observed through the transparent glass cover 14 without opening the storage box 133. At the same time, the storage box 133 can be conveniently opened or closed by rotating the combination of the hand nut 135 and the screw 134.

[0073] After the concrete mixture is solidified and formed in the test mold, corresponding tests can be carried out. During the test, the information on the storage component 13 can help identify and trace the specific information of each sample. After the test is completed, the test mold is removed as needed, and the sample is subsequently processed and analyzed. The information on the storage component 13 is still retained to facilitate subsequent data collation and report writing.
