Description

Technical Field

[0001] This invention relates to a concrete curing device that coordinates temperature and humidity control, belonging to the field of concrete construction technology. Background Technology

[0002] With the continuous development of social productivity and the increasing height of buildings, formwork equipment systems such as slipform, climbing formwork, and integral climbing steel platforms, as well as large-scale mechanical equipment such as internal climbing tower cranes, have emerged to meet the needs of formwork construction and on-site concrete construction for tall buildings. Among these equipment, corbels or load-bearing pins are widely used as cantilever support components for concrete structures, mainly bearing large vertical loads and a certain amount of horizontal tension in engineering projects. The corbels or load-bearing pins extend into the opening and rest on the concrete at the bottom of the opening. The concrete at the bottom of the opening needs to bear the weight of the equipment itself, which is a large load. During construction, additional construction loads from materials, workers, concrete placing booms, construction elevators, etc., must also be added. The stress on the concrete at the bottom of the opening also depends on the contact area with the load-bearing pins or corbels. For construction safety, it is essential to ensure the strength of the concrete at the bottom of the opening, making the curing of the concrete at the bottom of the opening particularly important.

[0003] During winter construction, the significant temperature difference between the inside and outside of concrete makes it prone to cracking. Furthermore, the diffusion of moisture in winter concrete easily leads to drying shrinkage cracks. The concrete at the bottom of openings is directly exposed to air after formwork removal, necessitating heating and humidification curing to ensure the quality of the concrete structure. Traditional methods for concrete heating and curing include moist heat curing, electric heating curing, and heated sheds. However, in high-rise building construction, the working conditions are poor, making the construction of heated sheds impractical. Electric heating of the internal steel reinforcement is cumbersome and energy-intensive. Moist heat curing uses steam as a heat medium to accelerate concrete hardening, ensuring appropriate strength and good density during winter construction. However, current methods for curing the concrete at the bottom of openings require heating and humidification after formwork removal, missing the optimal curing period. Therefore, it is necessary to design a curing device specifically for the concrete at the bottom of openings. Summary of the Invention

[0004] In view of the problems existing in the curing of concrete at the bottom of the opening where the corbel or load-bearing pin rests, the present invention provides a concrete curing device with coordinated temperature and humidity control to cure the concrete at the bottom of the opening.

[0005] To solve the above technical problems, the present invention includes the following technical solutions:

[0006] A concrete curing device for coordinated temperature and humidity control includes a pre-embedded box body, and a controller, a drive motor, a temperature and humidity sensor, a humidifier, and a heater disposed within the pre-embedded box body.

[0007] The drive motor includes a vertically arranged drive rod, the bottom of the pre-embedded box body is a movable base plate, the bottom of the drive rod is connected to the movable base plate, and the drive motor can drive the movable base plate to move up and down;

[0008] The pre-embedded box body is also equipped with a water storage tank, and the humidifier is connected to the water storage tank; the humidifier includes an atomizing nozzle. When the movable base plate is at the bottom, the atomizing nozzle is located above the movable base plate. When the movable base plate moves upward, the atomizing nozzle is located below the movable base plate and can perform atomized spraying on the space below the movable base plate.

[0009] The controller receives temperature and humidity data collected by the temperature and humidity sensors and determines whether to perform humidification or heating maintenance. The controller can control the drive motor to rotate, causing the drive rod to move the movable base plate upward. It can also control the humidifier to spray mist onto the space below the movable base plate and control the heater to heat or keep the space below the movable base plate warm.

[0010] Furthermore, the pre-embedded box body also includes two side plates, a top plate, a back plate, and a sealing plate;

[0011] Two side panels are set in parallel and spaced apart. The back panel is set at the same end of the two side panels and welded to the end of the side panels. The top panel is welded to the top of the back panel and the side panels. The sealing plate is set opposite to the back panel and welded to the end of the side panels and the top panel.

[0012] The movable base plate is located at the bottom of the pre-embedded box body.

[0013] Furthermore, the pre-embedded box is equipped with a vertical partition and a horizontal partition, and the vertical partition and the sealing plate form a closed space, which serves as a water storage tank;

[0014] The horizontal partition divides the space between the vertical partition and the back panel into upper and lower parts. The upper part is used to install the drive motor and controller; the lower part is used to install the temperature and humidity sensor and heater.

[0015] Furthermore, when the initial strength of the concrete is between 0.4 and 0.5 MPa, the controller begins to determine whether the concrete environment is curing the concrete under the movable base plate based on the data transmitted by the temperature and humidity sensors.

[0016] Furthermore, the pre-embedded box is equipped with a built-in power supply to power the drive motor, heater, and humidifier; or, a lead wire is provided to power the device through an external power source.

[0017] Furthermore, a support rod is also provided inside the pre-embedded box, which can limit the maximum range of upward movement of the movable base plate.

[0018] Compared with existing technologies, this invention, by adopting the above technical solutions, has the following advantages and positive effects: The temperature and humidity coordinated control concrete curing device provided by this invention combines the functions of formwork and concrete curing into one. During the concrete pouring stage, it serves as a formwork for openings. After the concrete is poured, it provides timely curing for the concrete at the bottom of the opening. By accurately monitoring and controlling the temperature and humidity inside the pre-embedded box, it promotes the development of early-age strength of the concrete, effectively prevents the generation of temperature difference cracks in the structural concrete, and ensures that the pouring quality and load-bearing capacity of the concrete at the bottom of the opening meet the requirements. Moreover, this curing device is pre-installed inside the wall formwork, eliminating the need for additional high-altitude scaffolding for curing equipment during the concrete stage, ensuring the safety of high-altitude operations. Furthermore, the heating and humidification operation of the concrete steam curing process is fully automated, remotely controlled and monitored by on-site management personnel, making operation flexible and convenient, and improving construction efficiency.

[0029] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a concrete curing device for coordinated temperature and humidity control according to the present invention. The advantages and features of the present invention will become clearer from the following description. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0030] like Figures 1 to 4 As shown, this embodiment provides a concrete curing device with coordinated temperature and humidity control, comprising a pre-embedded box body 10, a controller 20, a drive motor 30, a temperature and humidity sensor 40, a humidifier 50, and a heater 60. This curing device is used to cure the concrete 5 at the bottom of the opening.

[0031] like Figures 1 to 4 As shown, the embedded box body 10 includes two side plates 11, a top plate 12, a movable bottom plate 13, a back plate 15, and a sealing plate 14. The two side plates 11 are arranged parallel and spaced apart. The back plate 15 is located at the same end of the two side plates 11 and is welded and fixed to the ends of the side plates 11. The top plate 12 is welded and fixed to the top of the back plate 15 and the side plates 11. The sealing plate 14 is arranged opposite to the back plate 15 and is welded and fixed to the ends of the side plates 11 and the top plate 12. The shape and size of the embedded box body 10 are consistent with the shape and size of the opening 2 to be constructed. Typically, the side view of the embedded box body 10 is a right trapezoid, that is, the bottom of the sealing plate 14 is flush with the bottom of the back plate 15, the height of the sealing plate 14 is greater than the height of the back plate 15, and the back plate is located inside the opening.

[0032] The pre-embedded box body 10 has multiple chambers. For example, the pre-embedded box body 10 has a vertical partition 16 and a horizontal partition 17. The vertical partition 16 and the sealing plate 14 form a closed space, which serves as a water storage tank 18. The horizontal partition 17 divides the space between the vertical partition 16 and the back plate 15 into upper and lower parts. The upper part is used to install the drive motor 30 and the controller 20. For example, the drive motor 30 and the controller 20 can be installed on the horizontal partition 17. The controller 20 can also be installed on the top plate 12, the back plate 15, the side plate 11, or the vertical partition 16. The lower part is used to install the temperature and humidity sensor 40 and the heater 60. The drive motor 30 can move the movable base plate 13 up and down in the space of the lower part through the drive rod 31 without touching the heater 60. The humidifier 50 is located at the bottom of the vertical partition 16 and is connected to the water storage tank 18. The humidifier 50 includes an atomizing nozzle. When the movable base plate 13 is at the bottom, the atomizing nozzle is located above the movable base plate 13. When the movable base plate 13 moves upward, the atomizing nozzle is located below the movable base plate 13 and can perform atomized spraying on the space below the movable base plate 13.

[0033] The controller 20 is used to receive temperature and humidity data collected by the temperature and humidity sensor 40 and determine whether to perform humidification or heating maintenance. The controller 20 can control the drive motor 30 to rotate, so that the drive rod 31 drives the movable base plate 13 to move upward. It can also control the humidifier 50 to perform atomized spraying and control the heater 60 to perform heating or heat preservation maintenance.

[0034] The temperature and humidity coordinated control concrete curing device provided in this embodiment can serve as a mold for the opening 2 in the concrete wall. It is pre-set inside the wall formwork and acts as the mold for the opening 2 during concrete pouring. When the concrete strength of the opening 2 reaches the required level, the controller 20 determines whether the concrete environment needs to be cured below the movable base plate 13 based on the data transmitted by the temperature and humidity sensor 40. When curing is required, the controller 20 controls the drive motor 30 to rotate, causing the drive rod 31 to move the movable base plate 13 upward, so that the atomizing nozzle of the humidifier 50 is positioned below the movable base plate 13. The curing humidity is controlled by the atomizing spray of the humidifier 50, and the curing temperature is controlled by heating or heat preservation by the heater 60. Therefore, the temperature and humidity coordinated control concrete curing device provided in this embodiment combines the functions of formwork and concrete curing. During the concrete pouring stage, it serves as the formwork for opening 2. After the concrete is poured, it promptly cures the concrete 5 at the bottom of the opening. By accurately monitoring and controlling the temperature and humidity inside the embedded box 10, it promotes the development of early-age strength of the concrete, effectively prevents the generation of temperature difference cracks in the concrete, and ensures that the pouring quality and load-bearing capacity of the concrete 5 at the bottom of the opening meet the requirements. Moreover, this curing device is pre-installed inside the formwork of wall 1, eliminating the need for additional high-altitude erection of curing equipment, ensuring the safety of high-altitude operations. Furthermore, the heating and humidification operation of the concrete steam curing process is fully automated, remotely controlled and monitored by on-site management personnel, making operation flexible and convenient, and improving construction efficiency.

[0035] In one specific embodiment, the drive rod 31 includes a threaded rod and a threaded sleeve. The threaded sleeve fits around the threaded rod and is threadedly connected to it. The bottom of the threaded rod is fixedly connected to the movable base plate 13. Rotation of the drive motor 30 causes the threaded sleeve to rotate around the threaded rod, thereby moving the movable base plate 13 upward. Furthermore, to protect the upper heater 60, a support rod 19 can be installed within the pre-embedded housing. The support rod is located above the movable base plate and below the heater. The support rod 19 can limit the maximum upward movement of the movable base plate 13. When the movable base plate 13 moves upward and abuts against the support rod 19, it stops moving upward. For further linkage, a control switch can be installed on the support rod 19. When the movable base plate 13 approaches the support rod 19, it will trigger the control switch, stopping the drive motor 30. The support rod 19 can be installed on the back plate 15 or the side plate 11, or its top can be located below the transverse partition 17 and its bottom below the heater 60.

[0036] In one specific embodiment, the temperature and humidity sensor 40 uses an integrated temperature and humidity probe as the temperature measuring element, with a temperature measurement range of -20 to 120°C and a humidity measurement range of 0 to 100% RH, for detecting curing temperature and atomized humidity. When the temperature and humidity sensor 40 detects a temperature higher than a preset value, the heater 60 automatically cuts off the power to prevent the concrete from being damaged by excessive temperature, and issues a warning to the management personnel through the controller 20.

[0037] In one specific embodiment, heater 60 uses a heating tube or resistance wire for heating.

[0038] It should be noted that the power supply for the drive motor 30, heater 60, and humidifier 50 can be a portable power supply installed in the pre-embedded box, or it can be connected to an external power source via lead wires. To reduce the space required for the water storage tank 18, the water storage tank 18 can be supplied with water through an external water pipe.

[0039] In one specific embodiment, such as Figure 4 As shown, when the formwork for wall 1 is erected, the curing device is pre-positioned at an appropriate location inside the formwork, and then the formwork on both sides is fixed with tie bolts 4. During concrete construction, the movable base plate 13 is located at the bottom of the embedded box body 10, and the curing device is poured into the concrete. After the concrete has initially set, when the initial strength is determined to be between 0.4 and 0.5 MPa based on the age or other methods, the controller 20 starts to determine whether the concrete environment needs to cure the concrete 5 at the bottom of the opening based on the data transmitted by the temperature and humidity sensor 40, and adjusts the temperature and humidity as needed. After the concrete 5 at the bottom of the opening has cured, the curing device is removed.

[0040] In one specific embodiment, to ensure the sealing performance of the movable base plate 13 during concrete pouring, sealing rubber blocks are provided at the four edges of the movable base plate. The sealing rubber blocks are elastic and can seal the gaps around the movable base plate to prevent concrete from entering the interior of the embedded box. The sealing rubber blocks can be set on the side plates, back plates, and vertical partitions and do not move up and down with the movable base plate, or they can be sleeved on the movable base plate and move up and down with it.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
