Description

Technical Field

[0001] This application belongs to the field of precast T-beam curing technology, and particularly relates to a precast T-beam atomized curing shed and curing process. Background Technology

[0002] Currently, precast T-beams are the most commonly used superstructure in highway bridge engineering. Typically, the reinforcing steel for precast T-beams is processed into semi-finished products at a steel processing plant, then transported to the T-beam prefabrication yard for installation on the prefabrication pedestals. Finally, the formwork is closed and the T-beam concrete is poured. After the wet joint has reached the required strength for demolding, the bottom formwork of the wet joint is removed. After the T-beam is removed, the concrete needs to be cured for at least 7 days. Traditional curing methods often involve sprinkling water or covering with wet burlap sacks, resulting in uneven curing, difficulty in precisely controlling humidity, affecting the quality of the T-beam, and wasting a significant amount of water. To address this issue, Chinese patent CN223147384U discloses a mobile steam curing shed for precast beams. This shed contains steam pipes with numerous steam holes, through which steam is released to cure the precast T-beams. This curing method can improve curing uniformity and reduce water waste to some extent. However, in actual curing, it was found that the steam released through the steam holes, due to its low pressure, failed to directly reach the T-beam surface, and most of the steam rose to the top of the curing shed, resulting in an unsatisfactory curing effect. Furthermore, as the amount of steam increases, steam accumulates in the upper part of the shed while insufficient steam is found in the lower part, causing uneven curing of the T-beams and affecting their overall strength. Increasing the steam pressure will cause the steam to consistently blow onto the same part of the T-beam, resulting in localized overheating and humidification while other areas remain too dry. Insufficient localized humidification can lead to an evaporation rate exceeding the internal hydration rate, causing shrinkage cracks. Irregular network cracks or longitudinal cracks along the reinforcing bars may appear on the surface. Initially, these cracks are small (0.1~0.5mm), but they gradually widen over time due to stress concentration. In severe cases, the cracks may penetrate the surface and extend deep into the interior, becoming channels for rainwater and corrosive media to seep in later, directly threatening structural safety. In particular, the steam, influenced by airflow and gravity, cannot reach the connection between the web and flange during its movement. This area has the highest stress concentration and is a weak point prone to future cracking. The inability of steam to effectively cover this area leads to lower local strength, causing stress concentration under load, premature plastic deformation or localized failure, and affecting the overall load-bearing capacity. Summary of the Invention

[0003] This application provides a precast T-beam atomized curing shed and curing process to solve the technical problem of how to prevent steam from rising to the top of the shed, causing uneven curing between the upper and lower parts, and how pressurization can lead to localized excessive moisture or dryness, resulting in uneven curing of the precast T-beams, under the premise of reducing water waste by using steam for curing existing precast T-beams.

[0004] The technical solution adopted in this application is as follows: A prefabricated T-beam atomization curing shed includes a shed body and fixed supports located inside the shed body and on the outside of the T-beam. The T-beam includes a wing plate and a web plate connected below the wing plate. The fixed supports include an upper support located above the wing plate and side supports located on both sides of the web plate. Both the upper support and the side supports extend longitudinally along the T-beam. The shed body is also equipped with a mist generating device and nozzles connected to the mist generating device. The nozzles include an upper nozzle fixed to the upper support and facing the wing plate, and a side nozzle fixed to the side supports and facing the web plate. The upper nozzle can swing back and forth laterally along the wing plate, and the side nozzles can swing back and forth vertically along the web plate. A guide plate is also hinged to the side support, with the end face of the guide plate close to the nozzle. The shed body is also equipped with a driving device for driving the guide plate to rotate. The guide plate and the nozzles can swing synchronously, and when the guide plate moves to the top, the extension line of the extended end of the guide plate passes at least through the connection between the web plate and the wing plate.

[0005] This application utilizes a mist-generating device and spray nozzles connected to it within the curing shed. Compared to traditional spraying methods, mist curing creates a fine water mist that keeps the concrete surface moist, effectively preventing surface cracking and moisture loss. Furthermore, the uniform distribution of the water mist allows the concrete to maintain a relatively constant humidity level during hardening, reducing shrinkage caused by moisture evaporation. The continuous humid environment provided by mist curing also promotes more uniform hardening, improving overall quality, including uniform concrete strength. Moreover, the wide coverage area of ​​the water mist allows for even penetration of the concrete surface, eliminating the need for excessive watering and saving significant water resources.

[0006] Simultaneously, by configuring the nozzles to include an upper nozzle fixed to the upper support and facing the wing plate, and a side nozzle fixed to the side support and facing the web plate, the T-beam can achieve all-round curing of the wing plate and web plate through the synergistic effect of the upper and side nozzles during atomized curing. The upper nozzle can oscillate laterally along the wing plate, and the side nozzle can oscillate vertically along the web plate. This oscillation during spraying ensures uniform coverage of the wing plate surface, while the vertical oscillation of the side nozzle ensures sufficient wetting of all parts of the web plate, further improving curing uniformity. This allows for more even wetting of all parts of the wing plate and web plate, avoiding localized cracking and uneven strength, thereby ensuring the overall stability and durability of the T-beam structure. In addition, a guide plate is hinged to the side support. The end face of the guide plate is set close to the side nozzle. The guide plate and the side nozzle can swing synchronously. During the synchronous swing of the side nozzle and the guide plate, after the side nozzle sprays water mist, it can be guided by the guide plate to move directly to the belly plate. This allows the water mist to cover the belly plate more accurately and ensures that the water mist penetrates the belly plate completely. This effectively avoids the situation where the water mist sprayed directly from the nozzle is not evenly covered on the belly plate due to turbulence caused by airflow and other factors during the movement. This further improves the maintenance effect on the belly plate.

[0007] Simultaneously, when the guide plate moves to its highest point, the extended line of its extended end passes at least through the connection between the web and the flange, ensuring that the water mist guided by the guide plate directly reaches this connection. This guarantees thorough wetting of the connection, eliminates blind spots in curing, and enhances the overall strength of the T-beam, especially at the high stress concentration points where the web and flange connect. It effectively prevents strength loss due to cracking at the connection, thereby comprehensively improving the structural stability and service life of the T-beam. Furthermore, after the water mist travels through the guide plate to the connection, it disperses upon impact, further wetting the lower surface of the flange, thus achieving comprehensive wet curing of the T-beam.

[0008] In a preferred embodiment of a prefabricated T-beam atomized curing shed, the side nozzles include a first side nozzle and a second side nozzle arranged vertically at intervals along the side support, and the guide plate includes a first guide plate located below the first side nozzle and a second guide plate located above the second side nozzle, with the upper end face of the first guide plate being adjacent to the first side nozzle and the lower end face of the second guide plate being adjacent to the second side nozzle.

[0009] By configuring the nozzles to include a first side nozzle and a second side nozzle arranged vertically at intervals along the side support, and the guide plate including a first guide plate below the first side nozzle and a second guide plate above the second side nozzle, with the upper end face of the first guide plate adjacent to the first side nozzle and the lower end face of the second guide plate adjacent to the second side nozzle, the first side nozzle can be guided by the upper end face of the first guide plate, while the second side nozzle can be precisely guided by the lower end face of the second guide plate. This allows the first guide plate to flip upwards to cover the upper half of the web and the connection between the web and the wing plate, while the second guide plate can flip downwards to cover the lower half of the web. This ensures that the water mist evenly covers all parts of the T-beam under the synergistic effect of the two guide plates, eliminating maintenance blind spots, further improving the uniform wetting effect of the overall structure, and enhancing the durability and stability of the T-beam. Furthermore, the dual guide vanes and dual-side nozzles can achieve a wider coverage area according to the actual size of the T-beam, adapting to the maintenance needs of different T-beam structures, ensuring thorough wetting without dead angles, and improving the applicability of maintenance. It can also increase the spray frequency of each part of a single side nozzle, improving maintenance efficiency.

[0010] In a preferred embodiment of a prefabricated T-beam atomized curing shed, both the first guide plate and the second guide plate are arc-shaped from one side of the side support to the side of the web plate, with the first guide plate protruding downward and the second guide plate protruding upward.

[0011] By setting the first and second guide plates to be arc-shaped from the side support to the web side, with the first guide plate protruding downwards and the second guide plate protruding upwards, the water mist, guided by the arc-shaped first guide plate, forms an upward-sloping water mist flow upon detaching from the guide plate. This effectively covers the upper half of the web, the connection between the web and the wing plate, and the bottom surface of the wing plate. This reduces the upward swing amplitude of the first guide plate and the first side nozzle, increases the reciprocating swing frequency of the first guide plate and the first side nozzle, and further improves spray efficiency. Simultaneously, guided by the second guide plate, the water mist forms a downward-sloping water mist flow upon detaching from the second guide plate, effectively covering the lower half of the web. This reduces the downward swing amplitude of the second guide plate and the second side nozzle, increases the reciprocating swing frequency of the second guide plate and the second side nozzle, ensures uniform water mist coverage of all parts of the T-beam, optimizes maintenance effects, and extends the service life of the T-beam.

[0012] In a preferred embodiment of a prefabricated T-beam atomized curing shed, the first side nozzle is located above the vertical center of the side support, and the second side nozzle is located below or above the vertical center of the side support.

[0013] By positioning the first side nozzle above the vertical center of the side support, it is closer to the upper half of the T-beam web and the connection between the web and the wing plate. This allows the water mist to cover the target area in a shorter distance when sprayed upwards, reducing water mist diffusion loss and lowering the probability that the water mist will not reach the target area due to gravity and airflow. This ensures precise water mist coverage and improves the maintenance effect. Simultaneously, the second side nozzle is positioned below the vertical center of the side support, close to the lower half of the web. This ensures that the water mist quickly covers this area when sprayed downwards, reducing water mist loss and enhancing the uniformity of maintenance.

[0014] In a preferred embodiment of a prefabricated T-beam atomized curing shed, the T-beam further includes a bottom plate connected to the underside of the web plate, and the shed body is also provided with a support seat supporting the bottom plate, and the support seat is hollowed out. The nozzle also includes a lower nozzle for spraying the bottom plate.

[0015] By incorporating a support base within the shed that rests beneath the base plate, and by including a lower spray nozzle for spraying the base plate, the system ensures that the lower nozzle directly and evenly sprays the base plate, preventing cracks caused by dryness. This further enhances the overall maintenance effect of the T-beam and extends its service life. Simultaneously, the openwork support base design allows water mist to penetrate directly through the support base while simultaneously supporting the bottom of the T-beam, evenly covering the base plate. This further guarantees effective maintenance of the bottom of the T-beam, reduces obstruction of the spray by the support base, ensures comprehensive water mist coverage, and improves overall maintenance quality.

[0016] In a preferred embodiment of a prefabricated T-beam atomized curing shed, a diversion plate extending longitudinally along the T-beam is provided below the support base. The diversion plate has a V-shaped cross-section and the opening is oriented in the opposite direction, so that the vertical projection of the bottom plate falls entirely into the diversion plate.

[0017] By installing a V-shaped deflector plate extending longitudinally along the T-beam beneath the support base, with the opening facing the desired direction, some of the water mist sprayed downwards from the lower nozzles directly hits the upper surface of the base plate. The remaining downward-sprayed water mist bounces upwards after colliding with the deflector plate, covering the bottom surface of the base plate. This achieves comprehensive curing of the base plate, ensuring both the upper and lower surfaces are adequately moistened and preventing cracks caused by localized dryness. Simultaneously, the entire vertical projection of the base plate falls within the deflector plate, ensuring that the water mist continues to cover the entire base plate after bouncing, preventing water spillage and maximizing the curing effect, thus improving the overall quality and durability of the T-beam.

[0018] As a preferred embodiment of this application, this application also includes a curing process for a precast T-beam atomized curing shed, comprising the precast T-beam atomized curing shed as described above, the curing process including: S1: Transfer the precast T-beam to the curing shed and position it in the predetermined location using a positioning device; S2: A scanning device is installed inside the greenhouse to perform three-dimensional scanning of the T-beam and obtain the dimensional data of the T-beam. The dimensional data is transmitted to the control device connected to the nozzle, and the control device controls the swing angle of the nozzle according to the dimensional data. S3: After the curing time T, the precast T-beam will be transferred to the curing shed.

[0019] By applying the aforementioned curing process within the curing greenhouse, the T-beams can be precisely positioned after being transported there. A scanning device then performs a three-dimensional scan to obtain accurate dimensional data of the T-beams. The control device can then adjust the swing angle of the spray nozzles based on this data. For example, once the lateral dimensions of the wing plates are obtained, the swing angle of the upper spray nozzle can be controlled to ensure that the water mist sprayed from the upper nozzle completely covers the surface of the wing plates, ensuring uniform curing. Similarly, once the longitudinal dimensions of the web plates are obtained, the swing angle of the side spray nozzles can be controlled to ensure that the water mist sprayed from the side spray nozzles completely covers the web plates and the surface where the web plates connect to the wing plates. This ensures comprehensive curing of the entire T-beam structure, preventing localized over-drying or over-wetting, effectively preventing cracks and deformation, improving the overall strength and stability of the T-beams, and ensuring their safety and durability during use. By precisely controlling the swing angle of the nozzle, the nozzle can adaptively adjust according to T-beams of different sizes, ensuring that the water mist evenly covers all parts of the T-beam, avoiding maintenance blind spots, improving maintenance efficiency, and avoiding the problem of uneven maintenance of T-beams caused by applying the same maintenance plan to different T-beam sizes. This enables personalized maintenance strategies and ensures that each T-beam achieves the best maintenance effect.

[0020] In a preferred embodiment of a curing process for a precast T-beam atomized curing shed, the curing shed further includes a humidity sensor installed on the T-beam for detecting the real-time humidity of the T-beam, and the curing process further includes: Between S2 and S3 is S21, where the control device can control the spray flow rate and spray frequency of the nozzle by comparing the real-time humidity detected by the humidity sensor with a preset threshold.

[0021] The curing shed also includes a humidity sensor installed on the T-beam to detect the real-time humidity of the T-beam. The control device can compare the real-time humidity detected by the humidity sensor with a preset threshold to control the spray flow rate and spray frequency of the nozzles. This allows the control device to adjust the spray flow rate and spray frequency of the nozzles according to the real-time humidity of the T-beam. For example, when the humidity is too high, the spray flow rate and spray frequency can be reduced, and when the humidity is too low, the spray flow rate and spray frequency can be increased, so that the humidity of all parts of the T-beam is always kept within the optimal range. This avoids the problem of poor curing effect caused by excessive humidity fluctuations, ensures that the T-beam remains in a uniformly moist state during the curing process, further optimizes the curing effect, and improves the quality of the T-beam.

[0022] In a preferred embodiment of a curing process for a precast T-beam atomized curing shed, the humidity sensor includes a first humidity sensor located on the wing plate, a second humidity sensor located on the web plate, and a third humidity sensor located at the connection between the wing plate and the web plate. The curing process also includes: In S21, the control device can compare the real-time humidity detected by each humidity sensor with a preset threshold to individually control the spray flow rate and spray frequency of the top and side nozzles.

[0023] By configuring the humidity sensors to include a first humidity sensor located on the wing plate, a second humidity sensor located on the web plate, and a third humidity sensor located at the connection between the wing plate and the web plate, and by comparing the real-time humidity detected by each humidity sensor with a preset threshold, the control device can individually control the spray flow rate and spray frequency of the upper and side nozzles. This allows the control device to perform differentiated spraying based on the real-time humidity detected at different locations. For example, when the humidity of the wing plate is too low, the first humidity sensor can transmit the detected data to the control device. After receiving the data, the control device compares it with a preset threshold to increase the spray flow rate and spray frequency, ensuring that the humidity of the wing plate is suitable. Similarly, when the humidity of the web plate is too high, the second humidity sensor can transmit the detected data to the control device. After receiving the data, the control device compares it with a preset threshold to decrease the spray flow rate and spray frequency, ensuring that the humidity of the wing plate is suitable. This ensures that the humidity of all parts of the T-beam is balanced, avoiding localized over-wetness or over-dryness, thereby comprehensively improving the quality of maintenance.

[0024] In a preferred implementation of a curing process for a precast T-beam atomized curing shed, in S21, the curing time T includes an initial strong water retention period, a middle strength promotion period, and a later stable humidity period. During the initial strong water retention period, the spraying time is t1, the spraying flow rate is q1, and the spraying frequency is f1. During the middle strength promotion period, the spraying time is t2, the spraying flow rate is q2, and the spraying frequency is f2. During the later stable humidity period, the spraying time is t3, the spraying flow rate is q3, and the spraying frequency is f3, where q1 > q2 > q3 and f1 > f2 > f3.

[0025] By dividing the curing time T into three stages—the initial strong water retention period, the intermediate strength promotion period, and the later stable humidity period—with q1 > q2 > q3 and f1 > f2 > f3, the entire curing cycle of the T-beam is subdivided into three phases: In the initial strong water retention period, cement particles begin to hydrate, and it is necessary to avoid plastic shrinkage cracking caused by rapid evaporation of surface moisture. At this time, high-flow-rate, high-frequency spraying is required to maintain surface moisture. In the intermediate strength promotion period, the hydration reaction accelerates, and the internal strength develops rapidly. Medium-flow-rate, medium-frequency continuous replenishment of water is required to ensure that the hydration reaction proceeds fully. In the later stable humidity period, the hydration reaction tends to stabilize, and the hydration rate slows down. Only low-flow-rate, low-frequency spraying is required to avoid excessive water seeping into the concrete and causing lag in strength growth. This achieves precise and efficient humidity control during the curing process of the T-beam, ensuring that the curing objectives at each stage are achieved and improving the overall quality and durability of the T-beam. If the flow rate is fixed, it may lead to water shortage and cracking during the initial strong water retention period, insufficient water supply affecting strength during the mid-term strength promotion period, and excessive moisture reducing durability during the later stable humidity period. Flow rate control, on the other hand, can dynamically adjust to match the needs of each stage, achieving "on-demand water supply" and solving problems such as "over-curing," "under-curing," and "resource waste" that exist in traditional fixed-flow spraying. In the time dimension, the spray flow rate and frequency are dynamically adjusted to match the needs of the concrete hydration stage. In the spatial dimension, multiple nozzles and guide plates are used to form a three-dimensional atomization field to achieve three-dimensional spatial coverage, ultimately achieving the curing goals of "uniform humidity, sufficient hydration, reliable quality, and optimized cost."

[0033] like Figures 1 to 3As shown, this application discloses a precast T-beam 8 mist curing shed, including a shed body 1 and a fixed support set inside the shed body 1 and located outside the T-beam 8. The T-beam 8 includes a wing plate 81 and a web plate 82 connected below the wing plate 81. The fixed support includes an upper support 2 located above the wing plate 81 and side supports 3 located on both sides of the web plate 82. Both the upper support 2 and the side supports 3 extend longitudinally along the T-beam 8. The shed body 1 is also equipped with a mist generating device 7 and a nozzle connected to the mist generating device 7. The nozzle includes a nozzle fixed to the upper support 2. The upper nozzle 4 faces the wing plate 81 and the side nozzle 5 is fixed to the side bracket 3 and faces the web plate 82. The upper nozzle 4 can swing back and forth along the lateral side of the wing plate 81, and the side nozzle 5 can swing back and forth along the vertical side of the web plate 82. A guide plate 6 is also hinged on the side bracket 3. The end face of the guide plate 6 is close to the nozzle. The canopy 1 is also equipped with a drive device to drive the guide plate 6 to rotate. The guide plate 6 and the nozzle can swing synchronously. When the guide plate 6 moves to the top, the extension line of the extended end of the guide plate 6 passes through the connection between the web plate 82 and the wing plate 81 at least.

[0034] This application, by incorporating a mist-generating device 7 and nozzles connected to it within the shed 1, achieves a misting curing method that, compared to traditional spraying, generates a fine water mist. This keeps the concrete surface moist, effectively preventing surface cracking and moisture loss. Furthermore, due to the uniform distribution of the water mist, the concrete maintains a relatively constant humidity during the hardening process, reducing shrinkage caused by moisture evaporation. Simultaneously, the continuous humid environment provided by misting curing allows for more uniform hardening of the concrete, thus improving its overall quality. This includes enhancing the uniformity of concrete strength. Moreover, because the water mist covers a wide area and penetrates evenly onto the concrete surface, it eliminates the need for extensive watering, saving significant water resources.

[0035] Meanwhile, by configuring the nozzles to include an upper nozzle 4 fixed to the upper support 2 and facing the wing plate 81, and a side nozzle 5 fixed to the side support 3 and facing the web plate 82, the upper nozzle 4 and the side nozzle 5 can work together to achieve all-round maintenance of the wing plate 81 and the web plate 82 during atomized curing of the T-beam 8. The upper nozzle 4 can oscillate laterally along the wing plate 81, and the side nozzle 5 can oscillate vertically along the web plate 82. This oscillation of the upper nozzle 4 during spraying ensures uniform coverage of the wing plate 81 surface, while the vertical oscillation of the side nozzle 5 ensures that all parts of the web plate 82 are adequately moistened, further improving the uniformity of curing. This allows for more even wetting of the wing plate 81 and the web plate 82, avoiding localized cracking and uneven strength, thus ensuring the overall stability and durability of the T-beam 8 structure. In addition, a guide plate 6 is hinged to the side bracket 3. The end face of the guide plate 6 is set close to the side nozzle 5. The guide plate 6 and the side nozzle 5 can swing synchronously. During the synchronous swinging process of the side nozzle 5 and the guide plate 6, after the side nozzle 5 sprays water mist, it can be guided by the guide plate 6 to move directly to the web plate 82. This allows the water mist to cover the web plate 82 more accurately and ensures that the water mist fully penetrates the web plate 82. This effectively avoids the situation where the water mist sprayed directly from the nozzle becomes turbulent due to airflow and other factors during the movement, resulting in the water mist not being evenly covered on the web plate 82. This further improves the maintenance effect on the web plate 82.

[0036] Simultaneously, when the guide plate 6 moves to its highest point, the extension line of the extended end of the guide plate 6 passes at least through the connection between the web plate 82 and the wing plate 81, so that the water mist guided by the guide plate 6 can directly reach the connection between the web plate 82 and the wing plate 81, ensuring that the connection is fully moistened, eliminating maintenance dead spots, enhancing the overall strength of the T-beam 8, especially the high stress concentration area at the connection between the web plate 82 and the wing plate 81, effectively preventing strength reduction due to dry cracking at the connection, thereby comprehensively improving the structural stability and service life of the T-beam 8. Furthermore, after the water mist moves to the connection through the guide plate 6, it will disperse upon collision with the guide plate 6, thereby wetting the lower surface of the wing plate 81, achieving comprehensive moist curing of the T-beam 8.

[0037] Of course, the side nozzles 5 and the guide plate 6 are not limited to the point where the guide plate 6 moves to the top. The extension line of the extended end of the guide plate 6 passes through the connection between the web plate 82 and the wing plate 81. More preferably, during the movement of the guide plate 6, its extended end can achieve full coverage of the bottom surface of the wing plate 81, thereby achieving continuous wetting of the bottom surface of the wing plate 81 and the connection between the web plate 82, ensuring no dead angles in maintenance, and further improving the overall uniformity and durability of the T beam 8.

[0038] Specifically, such as Figure 2 , Figure 3As shown, the water mist sprayed from the upper nozzle 4 and the side nozzles 5 is fan-shaped, allowing each nozzle to cover a wider area. The side nozzles 5 are located on both sides of the web 82, ensuring uniform wetting on both sides. Furthermore, multiple upper nozzles 4 and side nozzles 5 are spaced along the longitudinal direction (length direction) of the T-beam 8 to achieve comprehensive, no-dead-angle curing of the entire length of the T-beam 8. There is minimal overlap at the edges of the water mist coverage areas of the upper nozzles 4 and the lower nozzles 14, ensuring comprehensive coverage while avoiding excessive humidity at overlapping areas. This achieves balanced wetting of all parts of the T-beam 8, preventing localized over-wetting or over-drying. In addition, multiple guide plates 6 can be installed, each oscillating synchronously with its corresponding side nozzle 5. Alternatively, only one guide plate 6 can be installed extending along the length of the T-beam 8. In this case, each side nozzle 5 moves synchronously with the guide plate 6, ensuring coordinated operation between the guide plate 6 and the side nozzle 5. This application does not specifically limit the driving device. Preferably, the driving device is a brushless motor that is connected to the guide plate 6 for transmission. The brushless motor and the side spray nozzles 5 are synchronously controlled by the same control device to ensure precise synchronization of the movements of the guide plate 6 and the side spray nozzles 5, further optimizing the water mist distribution. At the same time, the mist generating device 7 is not specifically limited; it can be an ultrasonic atomizer, a thermal evaporation device, etc. Preferably, the mist generating device 7 is a high-pressure micro-mist system. A high-pressure pump pressurizes water to an ultra-high pressure state, and then atomizes it into extremely fine water mist through specially designed nozzles, ensuring that the water mist particles are uniform and delicate, easily penetrate the air, and evenly cover all parts of the T-beam 8, improving the maintenance effect. The mist generating device 7 is connected to each spray nozzle through pipes.

[0039] It should be noted that this application does not specifically limit the configuration of the upper nozzle 4 and the side nozzle 5. As one preferred embodiment of this application, such as... Figure 2 , Figure 3 As shown, the side nozzle 5 includes a first side nozzle 51 and a second side nozzle 52 arranged vertically at intervals along the side support 3. The guide plate 6 includes a first guide plate 61 located below the first side nozzle 51 and a second guide plate 62 located above the second side nozzle 52. The upper end face of the first guide plate 61 is adjacent to the first side nozzle 51, and the lower end face of the second guide plate 62 is adjacent to the second side nozzle 52.

[0040] By configuring the nozzles to include a first side nozzle 51 and a second side nozzle 52 arranged vertically at intervals along the side support 3, the guide plate 6 includes a first guide plate 61 located below the first side nozzle 51 and a second guide plate 62 located above the second side nozzle 52. The upper end face of the first guide plate 61 is adjacent to the first side nozzle 51, and the lower end face of the second guide plate 62 is adjacent to the second side nozzle 52. This allows the first side nozzle 51 to be guided by the upper end face of the first guide plate 61, while the second side... The nozzle 52 can be precisely guided by the lower end face of the second guide plate 62, allowing the first guide plate 61 to flip upwards to cover the upper half of the web 82 and the connection between the web 82 and the wing plate 81. Simultaneously, the second guide plate 62 can flip downwards to cover the lower half of the web 82. This ensures that the water mist, under the synergistic effect of the two guide plates 6, evenly covers all parts of the T-beam 8, eliminating maintenance blind spots and further improving the uniform wetting effect of the overall structure, thus enhancing the durability and stability of the T-beam 8. Furthermore, the two guide plates 6 and the two side nozzles 5 can achieve a wider coverage area according to the actual size of the T-beam 8, adapting to the maintenance needs of different T-beam 8 structures, ensuring thorough wetting without dead angles, and improving the applicability of maintenance. It can also increase the spray frequency of each part of a single side nozzle 5, improving maintenance efficiency.

[0041] Of course, the side nozzles 5 are not limited to two; there can also be multiple side nozzles 5 arranged vertically at intervals along the side support 3. Each side nozzle 5 corresponds to a guide plate 6. The synchronous movement of each guide plate 6 and the side nozzle 5 is controlled by a control device to achieve precise adjustment of the swing angle of each side nozzle 5, ensuring that the water mist coverage area perfectly matches the structure of the T beam 8.

[0042] It should be further noted that this application does not specifically limit the structure of the first guide plate 61 and the second guide plate 62. As a preferred embodiment of this application, such as Figure 2 , Figure 3 As shown, the first guide plate 61 and the second guide plate 62 are both arc-shaped from the side of the side bracket 3 to the side of the web plate 82, and the protrusion direction of the first guide plate 61 is downward and the protrusion direction of the second guide plate 62 is upward.

[0043] By configuring the first guide plate 61 and the second guide plate 62 as arc-shaped sections from the side support 3 towards the side of the web 82, with the first guide plate 61 protruding downwards and the second guide plate 62 protruding upwards, the water mist, guided by the arc-shaped first guide plate 61, forms an upward-sloping water mist flow upon detachment from the guide plate 61. This effectively covers the upper half of the web 82, the connection between the web 82 and the wing plate 81, and the bottom surface of the wing plate 81, thereby reducing the impact on the first guide plate 61 and the first side nozzle 51. The slight upward swing amplitude increases the reciprocating swing frequency of the first guide plate 61 and the first side nozzle 51, thereby further improving the spraying efficiency. At the same time, guided by the second guide plate 62, the water mist forms a downward-sloping water mist flow when it leaves the second guide plate 62, effectively covering the lower half of the web plate 82. This reduces the downward swing amplitude of the second guide plate 62 and the second side nozzle 52, increases the reciprocating swing frequency of the second guide plate 62 and the second side nozzle 52, ensures that the water mist evenly covers all parts of the T-beam 8, optimizes the maintenance effect, and extends the service life of the T-beam 8.

[0044] Furthermore, in this embodiment, the first guide plate 61 can move below the horizontal plane during the flipping process, and the second guide plate 62 can move above the horizontal plane during the flipping process, so that the first guide plate 61 and the second guide plate 62 complement each other during the flipping process, ensuring that the water mist can fully cover the belly plate 82 and eliminate any potential maintenance dead corners.

[0045] Of course, the first guide plate 61 and the second guide plate 62 are not limited to the above-mentioned configuration. They can also be flat plates. When the first guide plate 61 and the second guide plate 62 are both flat plates, the first guide plate 61 and the second guide plate 62 can be abutted in a horizontal state, and the first guide plate 61 flips upward from the horizontal surface and the second guide plate 62 flips downward from the horizontal surface to achieve all-round coverage of the belly plate 82.

[0046] It should also be noted that this application does not specifically limit the location of the first side nozzle 51 and the second side nozzle 52. As a preferred embodiment of this application, the first side nozzle 51 is located above the vertical center of the side support 3, and the second side nozzle 52 is located below the vertical center of the side support 3.

[0047] By positioning the first side nozzle 51 above the vertical center of the side support 3, it is closer to the upper half of the web 82 of the T-beam 8 and the connection between the web 82 and the wing plate 81. This allows the water mist to cover the target area within a shorter distance when sprayed upwards, reducing water mist diffusion loss and lowering the probability that the water mist will not reach the target area due to the influence of gravity and airflow. This ensures precise water mist coverage and improves the maintenance effect. Simultaneously, the second side nozzle 52 is positioned below the vertical center of the side support 3, close to the lower half of the web 82. This ensures that the water mist quickly covers the area when sprayed downwards, reducing water mist loss and enhancing the uniformity of maintenance.

[0048] As a preferred embodiment of this application, such as Figure 2 , Figure 3 As shown, the T-beam 8 also includes a base plate 83 connected to the bottom of the web plate 82. The canopy 1 is also provided with a support seat 9 supporting the bottom plate 83, and the support seat 9 is hollowed out. The nozzle also includes a lower nozzle 14 for spraying the bottom plate 83.

[0049] By incorporating a support base 9 inside the shed 1 that rests beneath the base plate 83, and by designing the support base 9 to be openwork, and by including a lower nozzle 14 for spraying the base plate 83, the lower nozzle 14 can directly and evenly spray the base plate 83, preventing cracks from forming due to dryness. This further enhances the overall maintenance effect of the T-beam 8 and extends its service life. Simultaneously, the openwork design of the support base 9 allows water mist to penetrate directly through the support base 9 while simultaneously providing support to the bottom of the T-beam 8, evenly covering the base plate 83. This further ensures effective maintenance of the bottom of the T-beam 8, reduces obstruction of the spray by the support base 9, ensures comprehensive water mist coverage, and improves the overall maintenance quality.

[0050] Furthermore, such as Figure 2 , Figure 3 As shown, a diversion plate 10 extending longitudinally along the T-beam 8 is provided below the support base 9. The diversion plate 10 has a V-shaped cross section and the opening is oriented in the same direction. The vertical projection of the bottom plate 83 falls entirely into the diversion plate 10.

[0051] By installing a diversion plate 10 extending longitudinally along the T-beam 8 below the support base 9, the diversion plate 10 has a V-shaped cross-section with its opening facing the desired direction. This allows part of the water mist sprayed downwards from the lower nozzle 14 to be directly sprayed onto the upper surface of the base plate 83, while the other part of the downward-sprayed water mist bounces upwards after colliding with the diversion plate 10, covering the bottom surface of the base plate 83. This achieves all-round curing of the base plate 83, ensuring that both the upper and lower surfaces of the base plate 83 are fully moistened, preventing cracks caused by localized dryness. Simultaneously, the entire vertical projection of the base plate 83 falls within the diversion plate 10, ensuring that the water mist still covers the entire area of ​​the base plate 83 after bouncing, preventing water mist overflow, maximizing the curing effect, and improving the overall quality and durability of the T-beam 8.

[0052] As a preferred embodiment of this application, this application also includes a curing process for a precast T-beam 8 atomized curing shed, comprising the precast T-beam 8 atomized curing shed as described above, the curing process including: S1: Transfer the precast T-beam 8 to the curing shed and position it in the predetermined location using a positioning device; S2: A scanning device is installed inside the greenhouse. The scanning device performs a three-dimensional scan of the T-beam 8 and obtains the dimensional data of the T-beam 8. The dimensional data is transmitted to the control device connected to the nozzle. The control device controls the swing angle of the nozzle according to the dimensional data. S3: After the curing time T, the precast T beam 8 will be transferred to the curing shed at the location.

[0053] By applying the aforementioned curing process within the curing greenhouse, the T-beam 8 can be precisely positioned after being transported there and subjected to three-dimensional scanning using a scanning device. This allows for the acquisition of accurate dimensional data for the T-beam 8. The control device can then adjust the swing angle of the spray nozzles based on this data. For instance, once the lateral dimension of the wing plate 81 is obtained, the swing angle of the upper spray nozzle 4 can be controlled to ensure that the water mist sprayed from the upper spray nozzle 4 completely covers the surface of the wing plate 81, ensuring uniform curing. Similarly, once the longitudinal dimension of the web plate 82 is obtained, the swing angle of the side spray nozzle 5 can be controlled to ensure that the water mist sprayed from the side spray nozzle 5 completely covers the web plate 82 and the surface at the connection between the web plate 82 and the wing plate 81. This ensures comprehensive curing of the entire T-beam 8 structure, preventing localized over-drying or over-wetting, effectively preventing cracks and deformation, improving the overall strength and stability of the T-beam 8, and ensuring its safety and durability during use. By precisely controlling the swing angle of the nozzle, the nozzle can adaptively adjust according to the different sizes of T-beams 8, ensuring that the water mist evenly covers all parts of the T-beams 8, avoiding maintenance blind spots, improving maintenance efficiency, avoiding the problem of uneven maintenance of T-beams 8 caused by applying the same maintenance plan to different sizes of T-beams 8, realizing a personalized maintenance strategy, and ensuring that each T-beam 8 can achieve the best maintenance effect.

[0054] Specifically, after the T-beam 8 arrives on site, workers can use scanning devices such as laser 3D scanners or structured light 3D scanners to quickly scan the T-beam 8, obtain accurate 3D data, and transmit it to the control device. The control device then adjusts the swing angle of the nozzles in real time based on the data and the distance between the nozzles and the T-beam 8, ensuring that the water mist accurately covers all surfaces of the T-beam 8. Preferably, the upper nozzle 4 is located at the center of the width direction of the T-beam 8. For example, if the width of the wing plate 81 is measured to be 2.5 meters and the vertical distance between the upper nozzle 4 and the upper surface of the wing plate 81 is 1 meter, then the swing angle of the upper nozzle 4 should be set to ±55° to ensure that the water mist covers the entire wing plate 81. Similarly, if there is only one side nozzle 5 and the height of the web plate 82 is measured to be 3 meters and the horizontal distance between the side nozzle 5 and the side surface of the web plate 82 is 1.5 meters, then the swing angle of the side nozzle 5 should be set to ±50° to ensure that the water mist covers the entire web plate 82 and its connection with the wing plate 81. Of course, when there are multiple side nozzles 5, the control device can control the swing angle of each side nozzle 5 according to the measured data to ensure full coverage of the web plate 82. In addition, slide rails can be installed at the bottom of the side support 3 and at the connection with the upper support 2, so that the side support 3 can move relative to the upper support 2 along the length of the T-beam 8. After the T-beams of different lengths enter the site, the control device can adjust the spacing between each side support 3 according to the measured data, thereby adjusting the spacing between each side nozzle 5. At the same time, the fan-shaped angle of the water mist sprayed by each side nozzle 5 is adjusted to achieve seamless coverage of the side surface of the T-beam 8 by the water mist of each side nozzle 5, ensuring curing without dead angles.

[0055] Of course, it is not limited to measuring the dimensions of T-beams 8 through scanning devices. It can also pre-store the dimensional parameters of various models of T-beams 8 in the control device. When a new T-beam 8 arrives on site, the system automatically matches the corresponding parameters, quickly adjusts the spray nozzle swing angle, improves maintenance efficiency, reduces manual intervention, and ensures that each T-beam 8 can receive accurate and comprehensive maintenance.

[0056] In addition, it is not limited to transferring T-beam 8 to the maintenance shed. Rollers can also be installed at the bottom of the shed body 1 so that the shed body 1 can be moved by the rollers, so that the shed body 1 can adapt to the maintenance needs of T-beam 8 in different positions.

[0057] Furthermore, the maintenance shed also includes a humidity sensor installed on T-beam 8 to detect the real-time humidity of T-beam 8, and the maintenance process also includes: Between S2 and S3 is S21, where the control device can control the spray flow rate and spray frequency of the nozzle by comparing the real-time humidity detected by the humidity sensor with a preset threshold.

[0058] The curing shed also includes a humidity sensor installed on the T-beam 8 to detect the real-time humidity of the T-beam 8. The control device can compare the real-time humidity detected by the humidity sensor with a preset threshold to control the spray flow rate and spray frequency of the nozzles. This allows the control device to adjust the spray flow rate and spray frequency of the nozzles according to the real-time humidity of the T-beam 8. For example, when the humidity is too high, the spray flow rate and spray frequency can be reduced, and when the humidity is too low, the spray flow rate and spray frequency can be increased, so that the humidity of each part of the T-beam 8 is always kept within the optimal range. This avoids the problem of poor curing effect caused by excessive humidity fluctuations, ensures that the T-beam 8 is always kept in a uniformly moist state during the curing process, further optimizes the curing effect, and improves the quality of the T-beam 8.

[0059] Specifically, when it is necessary to control the humidity of T-beam 8 to above 90%, when the humidity sensor detects that the humidity is maintained above 90%, the control device will maintain the current spray state to ensure stable humidity; if the humidity is below 90%, the control device will control the nozzle to increase the spray flow and frequency until the humidity is restored to above 90%, thereby ensuring a constant and efficient maintenance environment for T-beam 8.

[0060] Furthermore, such as Figure 2 , Figure 3 As shown, the humidity sensor includes a first humidity sensor 11 disposed on the wing plate 81, a second humidity sensor 12 disposed on the web plate 82, and a third humidity sensor 13 disposed at the connection between the wing plate 81 and the web plate 82. The maintenance process also includes: In S21, the control device can compare the real-time humidity detected by each humidity sensor with a preset threshold to individually control the spray flow rate and spray frequency of the upper nozzle 4 and the side nozzle 5.

[0061] By configuring the humidity sensors to include a first humidity sensor 11 located on the wing plate 81, a second humidity sensor 12 located on the web plate 82, and a third humidity sensor 13 located at the connection between the wing plate 81 and the web plate 82, and by comparing the real-time humidity detected by each humidity sensor with a preset threshold, the control device can individually control the spray flow rate and spray frequency of the upper nozzle 4 and the side nozzle 5. This allows the control device to perform differentiated spraying based on the real-time humidity detected at different locations. For example, when the humidity of the wing plate 81 is too low, the first humidity sensor 11 can transmit the detected data to the control device. After receiving the data, the control device compares it with a preset threshold to increase the spray flow rate and spray frequency, ensuring that the humidity of the wing plate 81 is suitable. Similarly, when the humidity of the web plate 82 is too high, the second humidity sensor 12 can transmit the detected data to the control device. After receiving the data, the control device compares it with a preset threshold to decrease the spray flow rate and spray frequency, ensuring that the humidity of the wing plate 81 is suitable. This ensures that the humidity of each part of the T-beam 8 is balanced, avoiding local over-wetness or over-dryness, thereby comprehensively improving the maintenance quality.

[0062] As a preferred embodiment, in S21, the maintenance time T includes an initial strong water retention period, a mid-term strength promotion period, and a late-term stable humidity period. During the initial strong water retention period, the spraying time is t1, the spraying flow rate is q1, and the spraying frequency is f1. During the mid-term strength promotion period, the spraying time is t2, the spraying flow rate is q2, and the spraying frequency is f2. During the late-term stable humidity period, the spraying time is t3, the spraying flow rate is q3, and the spraying frequency is f3, where q1 > q2 > q3 and f1 > f2 > f3.

[0063] By dividing the curing time T into three stages—the initial strong water retention period, the intermediate strength promotion period, and the later stable humidity period—with q1 > q2 > q3 and f1 > f2 > f3, the entire curing cycle of T-beam 8 is subdivided into three phases: In the initial strong water retention period, cement particles begin to hydrate, and it is necessary to avoid plastic shrinkage cracking caused by rapid evaporation of surface moisture. At this time, high-flow-rate, high-frequency spraying is required to maintain surface moisture. In the intermediate strength promotion period, the hydration reaction accelerates, and internal strength develops rapidly. Medium-flow-rate, medium-frequency continuous replenishment of water is required to ensure sufficient hydration reaction. In the later stable humidity period, the hydration reaction tends to stabilize, and the hydration rate slows down. Only low-flow-rate, low-frequency spraying is required to avoid excessive water seeping into the concrete and causing lag in strength growth. This achieves precise and efficient humidity control during the curing process of T-beam 8, ensuring that the curing objectives at each stage are achieved and improving the overall quality and durability of T-beam 8. If the flow rate is fixed, it may lead to water shortage and cracking during the initial strong water retention period, insufficient water supply affecting strength during the mid-term strength promotion period, and excessive moisture reducing durability during the later stable humidity period. Flow rate control, on the other hand, can dynamically adjust to match the needs of each stage, achieving "on-demand water supply" and solving problems such as "over-curing," "under-curing," and "resource waste" that exist in traditional fixed-flow spraying. In the time dimension, the spray flow rate and frequency are dynamically adjusted to match the needs of the concrete hydration stage. In the spatial dimension, multiple nozzles and guide plates are used to form a three-dimensional atomization field to achieve three-dimensional spatial coverage, ultimately achieving the curing goals of "uniform humidity, sufficient hydration, reliable quality, and optimized cost."

[0064] Specifically, for example, the entire curing time T for T beam 8 is 14 days. The initial strong water retention period t1 is 3 days, q1 is 8~15L / h (adjusted according to the surface area of ​​beam 8; for easily dry parts such as wing plate 81 and web plate 82, the number of spray nozzles can be increased or the local flow rate can be increased appropriately), f1 is "5 on 10 off" or "10 on 10 off" (i.e., spray for 5~10 minutes, stop for 10 minutes); the mid-term strength promotion period t2 is 7 days, q2 is 6~12L / h, f2 is "10 on 15 off" or "10 on 20 off" (spray for 10 minutes, stop for 15~20 minutes); the late-term stable humidity period t3 is 4 days, q3 is 5~8L / h, f3 is "10 on 30 off" or "10 on 45 off" (spray for 10 minutes, stop for 30~45 minutes), or spray 2~3 times at fixed times every day (such as once in the morning and once in the evening) to ensure that there is no obvious dryness on the surface. This meticulous maintenance strategy not only effectively avoids many drawbacks of traditional maintenance methods, but also significantly improves the mechanical properties and durability of T-beam 8, providing a solid guarantee for the long-term stability of the project quality.

[0065] Furthermore, based on the above three-stage maintenance strategy, fine-tuning can be made according to changes in ambient temperature and humidity. Temperature sensors are also installed inside the greenhouse to monitor temperature changes in real time. Combined with humidity data, the spray system is intelligently controlled. Specifically, the surface humidity of T-beam 8 is used as the core trigger condition. When the surface humidity is < target value - 3% (e.g., initially < 92%): If the deviation is ≤5% (e.g., 95%→91%): increase the nozzle flow rate by 10%~15% (e.g., from 1.0L / min to 1.1~1.15L / min), and at the same time shorten the stop time of intermittent spraying (e.g., adjust from "10 on 15 off" to "10 on 10 off" in the middle period).

[0066] If the deviation is greater than 5% (e.g., 95% → 88%), increase the flow rate by 20% to 30% and turn on the "continuous spray mode" (until the surface humidity rises back to the target value + 2% and then resumes the intermittent mode), and focus on increasing the power of the nozzles in areas prone to water loss such as corners and ends.

[0067] When surface humidity > target value + 5% (e.g., initially > 100%, i.e., surface condensation): Reduce the flow rate to 70%~80% of the baseline value and extend the stop spraying time (e.g., adjust from "10 on 15 off" to "10 on 20 off" in the middle period). If the humidity continues to be too high (>5 minutes), stop spraying the corresponding area until the humidity drops back to within the target value +3%.

[0068] Similarly, temperature-coordinated compensation is used to correct the humidity adjustment range, specifically: High-temperature environment (temperature > sensitivity threshold): For every 3°C increase in temperature (e.g., from 25°C to 28°C), the rate of water evaporation increases by about 15% to 20%. In addition to humidity control, the flow rate needs to be increased by 5% to 10%, or the spray stop time needs to be shortened by 5 minutes (to avoid a sudden drop in surface humidity due to excessive evaporation).

[0069] For example, during mid-term maintenance, if the surface humidity drops to 88% (target 90%, deviation 2%), and the ambient temperature is 32℃ (sensitive threshold 30℃, exceeding 2℃), then the flow rate needs to be increased by 10% (basic adjustment) + 5% (temperature compensation) = 15%.

[0070] Low temperature environment (temperature < sensitivity threshold): When the temperature is <10℃, the hydration reaction slows down and the evaporation of water weakens. It is necessary to reduce the flow rate by 10%~20% or extend the time of stopping spraying (to avoid long-term water accumulation on the surface, which will lead to slow strength growth). If the temperature is close to the freezing point (<5℃), spraying should be stopped and the greenhouse should be closed for insulation to prevent freezing and damage to T-beam 8.

[0071] By combining the data from various sensors with the maintenance patterns of T-beam 8, "on-demand spraying" is achieved: ensuring the moisture requirements of T-beam 8 at different ages while avoiding resource waste or quality risks caused by excessive spraying, ultimately ensuring the uniformity of T-beam 8 maintenance and meeting strength standards.
