Description

Technical Field

[0001] The utility model belongs to the technical field of concrete engineering quality, and particularly relates to an embedded label for preventing the replacement of concrete test specimens. Background Technique

[0002] In order to supervise the quality of concrete projects, the supervision department generally requires witnessed sampling, that is, while pouring concrete on site, some concrete test specimens are made under the witness of supervisors as samples of the same batch of concrete. The construction unit sends these concrete test specimens to a third-party testing unit for testing, and the testing results of the third-party testing unit are used to reflect the quality of this concrete project. However, due to the characteristics of concrete, it takes a long time from pouring to forming and then to testing. During this period, the specimens may be replaced, thus affecting the supervision of the quality of concrete projects.

[0003] At present, in order to prevent the replacement of concrete specimens, generally there are the following two methods:

[0004] 1. The method of implanting a single two-dimensional code label is adopted to prevent the replacement of concrete test specimens. However, due to the characteristics of concrete, it takes a period of time from pouring to forming. During this period, the label can still be pulled out and then inserted into other specimens for replacement, resulting in the final test results being unable to correctly reflect the strength of the concrete.

[0005] 2. The implantable anti-replacement label for concrete test specimens using a main identification label and a slave identification label can prevent the replacement of specimens to a certain extent. However, due to the complex operation process of this method and the uneven levels of on-site operators at the construction site, the implementation difficulty increases, and even resistance occurs at the construction site. Content of the Utility Model

[0006] The purpose of the utility model is to provide an embedded label for preventing the replacement of concrete test specimens to solve the problem that concrete test specimens are easily replaced in the above-mentioned background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] An embedded label for preventing the replacement of concrete test specimens, comprising: a first fixing plate, four connecting plates are fixedly connected inside the first fixing plate, the end of the connecting plate far away from the first fixing plate is fixedly connected with a second fixing plate, four empty slots are formed between the first fixing plate and the second fixing plate through the connecting plates, a two-dimensional code identifier is arranged on the top of the first fixing plate, and the bottom of the second fixing plate is connected with a concrete test specimen.

[0009] Preferably, connection holes are formed on both sides of the bottom of the second fixing plate. A screw rod penetrates through the inside of the connection hole, and the surface of the screw rod penetrates through the inside of the second fixing plate. A fastening nut is threadedly connected to the surface of the screw rod, and the fastening nut is located on the top of the second fixing plate.

[0010] Preferably, fixing rods are fixedly connected to both sides of the bottom of the first fixing plate, and insertion cones are fixedly connected to the bottom ends of the fixing rods.

[0011] Preferably, a protective cover is arranged inside the empty groove. A connecting strip is fixedly connected to the top of the protective cover, and the adjacent two protective covers are connected by the connecting strip.

[0012] Preferably, a grip rod is fixedly connected to the top of the protective cover, and an anti-slip sleeve is fixedly connected to the surface of the grip rod.

[0013] Preferably, sealing gaskets are fixedly connected to the four circumferential parts of the surface of the protective cover, and the surface of the sealing gasket is connected to the inner side wall of the empty groove.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] (1) The hollow part of the anti-replacement label empty groove is filled with a water-soluble new material. After the label is implanted at the sampling site, the filled water-soluble new material begins to gradually dissolve and is dissolved within a short time to form a hollow. The color of the dissolved material adheres to the surface of the test piece, and the authenticity of the concrete test block can be intuitively judged by whether there is the color of the water-soluble material in the hollow part, which is more convenient and fast to judge the authenticity of the concrete test block.

[0016] (2) When the empty groove part is not in use, in order to prevent the water-soluble material placed inside the empty groove from dissolving in water, the empty groove is protected by the protective cover. At the same time, when the protective cover is protecting, through the cooperation with the sealing gasket, its sealing performance is better, ensuring that the water-soluble material inside the empty groove is not affected by water, and at the same time, the film made of the water-soluble material can be fixed, avoiding the situation that it cannot be fixed inside the empty groove and falling off randomly.

[0022] 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 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 shall fall within the protection scope of the present invention.

[0023] Embodiment 1:

[0024] Please refer to Figures 1 to 4 As shown, an embedded label for preventing the replacement of concrete specimens includes: a first fixing plate 1, four connecting plates 2 are fixedly connected inside the first fixing plate 1, one end of the connecting plate 2 away from the first fixing plate 1 is fixedly connected to a second fixing plate 3, and four empty slots 4 are formed between the first fixing plate 1 and the second fixing plate 3 through the connecting plates 2. A QR code label 5 is arranged on the top of the first fixing plate 1, and a concrete specimen 6 is connected to the bottom of the second fixing plate 3. Through the setting of the first fixing plate 1, the connecting plate 2 can be fixedly connected thereto, which is convenient for the subsequent connection of the second fixing plate 3 and it as a whole. Through the opening of the empty slots 4, it is convenient for the subsequent placement of water-soluble materials, and at the same time, it is convenient to clearly observe the dissolution traces after contacting with water and dissolving. It should be noted that the water-soluble material in this device is a water-soluble plastic film made of polyvinyl alcohol, which melts when it meets water. The staff can pre-dye a layer of dye inside it for subsequent observation. Through the QR code label 5, it is convenient for the staff to know whether the concrete specimen 6 is the original specimen.

[0025] Fixed rods 7 are fixedly connected to both sides of the bottom of the first fixing plate 1, and insertion cones 8 are fixedly connected to the bottom ends of the fixed rods 7. Through the setting of the fixed rods 7, the insertion cones 8 can be indirectly connected to the first fixing plate 1 to keep it stable. During operation, the whole label is pressed onto the surface of the specimen. The conical design of the insertion cone 8 can easily be pressed into the concrete specimen 6. However, when the concrete solidifies, the conical design of the insertion cone 8 makes it impossible to easily pull out the label from the surface of the specimen, ensuring the stability of the connection between the whole device and the concrete specimen 6.

[0026] Embodiment 2:

[0027] Please refer to Figure 1 、 Figure 2 andFigure 4 As shown in the figure, connection holes 9 are provided on both sides of the bottom of the second fixing plate 3. A screw rod 10 penetrates through the inside of the connection hole 9, and the surface of the screw rod 10 penetrates through the inside of the second fixing plate 3. A fastening nut 11 is threadedly connected to the surface of the screw rod 10, and the fastening nut 11 is located on the top of the second fixing plate 3. By providing the connection holes 9, the screw rod 10 can penetrate through its inside. By providing the fastening nut 11, the screw rod 10 can be fixed after being inserted into the connection hole 9.

[0028] A protective cover 12 is provided inside the empty groove 4. A connecting strip 13 is fixedly connected to the top of the protective cover 12, and the adjacent two protective covers 12 are connected by the connecting strip 13. By providing the protective cover 12, the water-soluble material located inside the empty groove 4 can play a certain protective role, avoiding accidental contact with water sources inside the empty groove 4, causing the water-soluble material to dissolve and resulting in waste of resources. By providing the connecting strip 13, the four protective covers 12 can be connected to each other to form a whole.

[0029] A grip rod 14 is fixedly connected to the top of the protective cover 12, and an anti-slip sleeve 15 is fixedly connected to the surface of the grip rod 14. By providing the grip rod 14, the four protective covers 12 can be lifted simultaneously. By providing the anti-slip sleeve 15, the grip rod 14 is more stable when lifted.

[0030] Sealing gaskets 16 are fixedly connected to the four peripheral portions of the surface of the protective cover 12, and the surface of the sealing gasket 16 is connected to the inner side wall of the empty groove 4. By providing the sealing gaskets 16, the protective cover 12 has better sealing performance when closing the empty groove 4, avoiding water droplets on the protective cover 12 from flowing into the inside of the empty groove 4 through its top.

[0031] Working principle of the utility model: The staff pre-places a film made of water-soluble material at the bottoms of the first fixing plate 1 and the second fixing plate 3, and drills holes corresponding to the positions of the insertion cones 8 on the film, or directly passes the film through the insertion cones 8 to form holes, ensuring that the film fits the bottoms of the first fixing plate 1 and the second fixing plate 3. At this time, the empty slot 4 is blocked. Subsequently, the staff inserts the screw rod 10 into the connecting hole 9 until the surface of the screw rod 10 penetrates through the inside of the connecting hole 9. At this time, the staff screws the fastening nut 11 onto the surface of the screw rod 10 to connect the screw rod 10 with the second fixing plate 3. The above operations are those of the staff during product production. When the user gets it, the water-soluble material is already under the device and can be used directly. Then, the staff places the first fixing plate 1 and the second fixing plate 3 on the concrete specimen 6. At this time, the fixing rods 7 and the insertion cones 8 are inserted into the concrete specimen 6. When sampling and implanting the label, the concrete specimen 6 is in a soft state. During the operation, the whole device is pressed onto the surface of the specimen to expose the QR code label 5. Before the specimen solidifies, a sampling photo of the surface of the specimen exposing the QR code label 5 on the label surface is taken on-site, and then the sampling photo and the relevant shooting information during shooting are transmitted to the platform. Then, the specimen is sent to the testing unit. After receiving the specimen, the testing unit first checks whether the anti-replacement label is complete and whether there are color features left after the water-soluble material in the hollow part of the label empty slot 4 is dissolved. If the label is incomplete or there is no color left after the water-soluble material in the hollow part of the label empty slot 4 is dissolved, the specimen can be determined to be invalid. Secondly, the QR code label 5 on the anti-replacement label on the surface of the specimen is scanned to obtain the sampling information of the specimen from the platform, and at the same time, a comparison photo is taken. The system automatically compares the features of the sampling photo and the comparison photo. If the comparison passes, the specimen is determined to be valid; otherwise, the specimen is determined to be invalid. The conical design of the insertion cone 8 can easily be pressed into the concrete specimen 6, but when the concrete solidifies, the conical design of the insertion cone 8 makes it impossible to easily pull out the label from the surface of the specimen. When the label implantation is completed at the sampling site, the dissolvable part of the label begins to gradually dissolve. Before the concrete completely solidifies, the soluble part gradually dissolves, and the water-soluble material in the empty slot 4 is dissolved in water to form a hollow, which can visually observe that this label has been used and cannot be placed on other concrete specimens 6 for the second time, thus achieving the function of preventing the replacement of the concrete specimen 6.

[0032] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
