Description

Technical Field

[0001] The present invention belongs to the technical field of building maintenance, and more specifically, relates to a device for electromagnetic maintenance of reinforced concrete. Background Art

[0002] Reinforced concrete is a composite material composed of two materials: steel bars and concrete. Its maintenance refers to the process of controlling the ambient temperature, humidity and other conditions after the concrete is poured and formed to ensure the normal cement hydration reaction.

[0003] A search of the Chinese patent publication number "CN117569573A" discloses a "steel heatable mold for concrete columns and its use method." This mold is used to enclose the concrete pouring area. The column angle steel formwork and the flat steel formwork are welded together to form an integrated structure. The mold has few joints, high smoothness, and high strength, ensuring the flatness, verticality, and appearance of the reinforced concrete column construction surface. At the same time, the installation of electric heating cables and a detachable power supply can heat and insulate the reinforced concrete column, ensuring the coagulation strength and quality of the reinforced concrete column.

[0004] Based on the above search and combined with the existing technology, it was found that the above patent has certain defects: when the mold heats the concrete, the heat emitted by the electric heating tape is used to heat the surface of the mold as a whole, and the concrete cannot be heated from the inside out, which leads to a longer heating process and lower efficiency. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a device for electromagnetic maintenance of reinforced concrete to solve the above problems.

[0007] An adaptive electromagnetic maintenance structure is fixedly installed on the upper end of the inner plate

[0008] The adaptive electromagnetic maintenance structure includes a spring-type electromagnetic heating device, a plurality of inner stop columns are fixedly installed on the upper end of the inner plate, each of the inner stop columns is located on the inner side of the spring-type electromagnetic heating device, a pressure plate is fixedly installed on the upper end of the spring-type electromagnetic heating device, the pressure plate is located inside the column and is slidably installed, an upper fixed shell is fixedly installed on the outside of the column, an electric push rod is fixedly installed inside the upper fixed shell, four-corner transmission rods are fixedly installed on the circumferential surface of the output shaft of the electric push rod, the four-corner transmission rods are fixedly installed with the pressure plate, and a plurality of through grooves are opened through the inside of the pressure plate.

[0009] Preferably, the electric push rod can be started by compressing the electromagnetic spring of the spring-type electromagnetic heating device downward through the four-corner transmission rods and the pressure plate. Each of the through slots is parallel to the inner block column, and each of the through slots is slidably installed with the inner block column. A storage slot is opened through the center of the pressure plate, and the storage slot is located on the inner side of the through slot. A blower is provided inside the storage slot, and a plurality of sliding slots are opened on the inner wall of the column.

[0010] Preferably, an insulating layer is provided on the inner wall of the column, and the insulating layer can isolate the heat inside the column from being transferred to the surface of the column. Sliders are symmetrically fixedly installed on the circumferential surface of the pressure plate, and each of the slides is slidably installed with the slide groove. A plurality of circulation grooves are provided on the circumferential surface of the column, and a U-shaped tube is provided between each group of the circulation grooves.

[0011] Preferably, each of the two ends of the U-shaped tube is respectively provided with a first one-way valve and a second one-way valve, the first one-way valve can transport the hot air inside the U-shaped tube to the inside of the column, and the second one-way valve can transport the hot air inside the column to the inside of the U-shaped tube, the lower end of the column is provided with a stepped base, and the upper end of the upper fixed shell is provided with a hanging ring.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

In the process of the electric push rod driving the four-corner transmission rod and the pressure plate compressing the spring-type electromagnetic heating device, the directional sliding of the slider in the slide groove and the guiding effect of the inner stop column in the through groove realize the highly adaptive installation of the device to concrete columns of different specifications, providing a structural foundation for subsequent heating efficiency and improving applicability.

[0014] In the present invention, after the spring-type electromagnetic heating device is started, a high-frequency electromagnetic field is used to generate an eddy current effect in the steel bar, which can increase the temperature of the steel bar and simultaneously heat the concrete from the inside through heat conduction, thereby improving the heating effect of the concrete, promptly stabilizing the steel bar, avoiding subsequent deviation and other problems, and improving the maintenance quality;

[0015] In the present invention, by providing a blower, the forced airflow introduced by the blower forms a circulating heat field within the column to assist in heating the surface of the concrete column. In combination with the adaptive electromagnetic curing structure, the interior and exterior of the concrete column can be heated simultaneously, thereby greatly improving the curing efficiency and quality of the concrete column.

[0026] See also Figures 1-6 The present invention provides a device for electromagnetic curing of reinforced concrete, comprising a column 11, an inner plate 12 fixedly mounted on the inner side of the column 11:

[0027] An adaptive electromagnetic maintenance structure is fixedly mounted on the upper end of the inner plate 12;

[0028] The adaptive electromagnetic maintenance structure includes a spring-type electromagnetic heating device 13, a plurality of inner blocking columns 14 are fixedly installed on the upper end of the inner plate 12, each inner blocking column 14 is located on the inner side of the spring-type electromagnetic heating device 13, a pressure plate 15 is fixedly installed on the upper end of the spring-type electromagnetic heating device 13, the pressure plate 15 is located inside the column 11 and is slidably installed, an upper fixed shell 16 is fixedly installed on the outside of the column 11, an electric push rod 17 is fixedly installed inside the upper fixed shell 16, and a four-corner transmission rod 18 is fixedly installed on the circumferential surface of the output shaft of the electric push rod 17. The movable rod 18 is fixedly installed with the pressure plate 15. A plurality of through slots 19 are formed inside the pressure plate 15. The activation of the electric push rod 17 can compress the electromagnetic spring of the spring-type electromagnetic heating device 13 downward through the four-corner transmission rods 18 and the pressure plate 15 (the spring-type electromagnetic heating device 13 is a device with a heating function and a spring-shaped structure. The electromagnetic spring, as part of the overall structure, can be compressed by the pressure plate 15 when driven by the electric push rod 17 and other components. The electromagnetic spring is a structure in the device that has spring characteristics and can be related to the electromagnetic heating function);

[0029] By providing the inner stop column 14, the problem of a large displacement of the electromagnetic spring of the spring-type electromagnetic heating device 13 when it is compressed can be avoided;

[0030] By setting the lifting ring 32 and cooperating with the crane, the staff can quickly complete the positioning of the device and the reinforced concrete column. In the process of the electric push rod 17 driving the four-corner transmission rod 18 and the pressure plate 15 to compress the electromagnetic spring of the spring-type electromagnetic heating device 13, the directional sliding of the slider 25 in the slide groove 23 and the guiding effect of the inner stop column 14 in the through groove 19 realize the highly adaptive device to concrete columns of different specifications, providing a structural foundation for subsequent heating efficiency and improving applicability.

[0031] After the spring-type electromagnetic heating device 13 is started, it uses a high-frequency electromagnetic field to generate an eddy current effect in the steel bars, which can increase the temperature of the steel bars and simultaneously heat the concrete from the inside through heat conduction, thereby improving the heating effect of the concrete, stabilizing the steel bars in time, avoiding subsequent problems such as deviation, and improving the maintenance quality.

[0032] Each through slot 19 is parallel to the inner stop column 14 and is slidably mounted on the inner stop column 14. A storage slot 21 is formed through the center of the pressure plate 15 and is located on the inner side of the through slot 19.

[0033] A blower 22 is provided inside the storage slot 21, a plurality of chute grooves 23 are provided on the inner wall of the column 11, and an insulating layer 24 is provided on the inner wall of the column 11. The insulating layer 24 can isolate the heat inside the column 11 from being transferred to the surface of the column 11. Sliders 25 are symmetrically fixedly installed on the circumferential surface of the pressure plate 15, and each slider 25 is slidably installed with the chute 23. A plurality of circulation grooves 26 are provided on the circumferential surface of the column 11;

[0034] By setting up the blower 22, the forced airflow introduced by the blower 22 forms a circulating heat field in the column 11 to assist in heating the surface of the concrete column. Combined with the adaptive electromagnetic curing structure, the concrete column can be heated both inside and outside at the same time, thereby greatly improving the curing efficiency and quality of the concrete column.

[0035] A U-shaped tube 27 is provided between each set of circulation grooves 26. A first one-way valve 28 and a second one-way valve 29 are provided at the ends of each U-shaped tube 27. The first one-way valve 28 can transport the hot air inside the U-shaped tube 27 to the inside of the column 11, and the second one-way valve 29 can transport the hot air inside the column 11 to the inside of the U-shaped tube 27.

[0036] By providing the U-shaped tube 27 and the first one-way valve 28 and the second one-way valve 29, a portion of the wind enters the interior of the U-shaped tube 27 through the second one-way valve 29 at the lower end of the U-shaped tube 27 and is discharged through the second one-way valve 29. This can force a portion of the hot air to undergo heat circulation through the U-shaped tube 27 inside the column 11, effectively solving the problem of curing large-volume concrete with cold top and hot bottom, and further improving the curing efficiency and quality.

[0037] A stepped base 31 is provided at the lower end of the column 11, and a hanging ring 32 is provided at the upper end of the upper fixed shell 16;

[0038] By providing the lifting ring 32, the device can be carried as a whole and can be conveniently mounted on a concrete column.

[0039] Working principle:

[0040] In the first step, when using, the staff can first connect the sling with the lifting ring 32, and operate the crane to put the entire device on the outside of the reinforced concrete column. Then the staff can turn on the electric push rod 17, so that the output shaft of the electric push rod 17 compresses the electromagnetic spring of the spring-type electromagnetic heating device 13 downward through the four-corner transmission rod 18 and the pressure plate 15, so that the height of the spring-type electromagnetic heating device 13 matches the height of the reinforced concrete column;

[0041] In the second step, when the pressing plate 15 moves, the pressing plate 15 will drive the slider 25 to slide inside the slide groove 23. At the same time, the inner blocking column 14 will actively slide with the through groove 19. Then the staff can turn on the spring-type electromagnetic heating device 13, so that the spring-type electromagnetic heating device 13 uses the electromagnetic induction principle to heat the steel bars in the concrete, and then transfer the heat to the concrete, thereby achieving the purpose of curing the concrete. At this time, a certain amount of heat will be generated inside the column 11. Then the staff can turn on the blower 22, so that the blower 22 blows air into the column 11, so that the hot air can simultaneously perform auxiliary heat treatment on the surface of the concrete column, and part of the hot air will be discharged through the stepped base 31;

[0042] In the third step, at the same time, some of the hot air will enter the interior of the U-shaped tube 27 through the second one-way valve 29 on the U-shaped tube 27, and will eventually be discharged through the first one-way valve 28, so that the hot air will circulate for the second time from a distance near the top of the reinforced concrete column for waste heat treatment.

Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described in order to better illustrate the principles of the invention and its practical application and to enable those skilled in the art to understand the invention and design various embodiments with various modifications as suited for specific applications.
