Description

Technical Field

[0001] This invention relates to the field of concrete curing equipment technology, and in particular to a curing device and method for concrete in high-altitude and cold regions. Background Technology

[0002] The core of concrete curing in high-altitude and cold regions is to resist the various adverse effects of low temperatures. The increase in concrete strength relies on the cement hydration reaction, and the rate of this reaction is directly limited by the ambient temperature. When the temperature drops to 5°C, the hydration process slows down significantly, and when it drops to 0°C, the internal water freezes, and the hydration reaction basically stops. This not only causes slow strength growth and makes it difficult to meet the required strength, but the volume expansion caused by the freezing of water also creates internal stress, which can easily lead to internal micro-cracks. Repeated freeze-thaw cycles will further expand the damage, seriously impairing the density and durability of the components.

[0003] Given the aforementioned hazards of low temperatures, insulated sheds are commonly used for the insulation and curing of cast concrete components in high-altitude and cold regions. However, most existing conventional insulated sheds are fixed in their layout. After completing the insulation and curing work on a batch of components, all components must be moved out of the site before the next batch of components can be cured. This process is time-consuming and cumbersome, directly resulting in low overall curing efficiency.

[0004] Therefore, this application proposes a curing device and method for concrete in cold regions. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background art by proposing a curing device and method for concrete in cold regions.

[0006] On one hand, the technical solution of the present invention is: a curing device for concrete in cold regions, comprising a C-shaped cage, and further comprising: a heating mechanism installed inside the C-shaped cage, wherein both ends of the C-shaped cage are provided with openings, and each opening is equipped with a sealing mechanism for sealing the openings; a pulling component installed at both ends of the C-shaped cage corresponding to the sealing mechanism, the pulling component being used to drive the sealing mechanism to complete the opening action by manually pulling; and a sliding mechanism disposed at the bottom of the C-shaped cage, the sliding mechanism being used to support the C-shaped cage to slide horizontally alternately.

[0007] Optionally, the sealing mechanism includes cavities disposed within a C-shaped cage, each cavity having a rotatably connected winding shaft inside, each cavity having a through groove at its bottom, and a shielding cloth wound around the outside of the winding shaft. One end of the shielding cloth movably passes through the through groove and is fitted with a sliding member, which is slidably fitted into the opening.

[0008] Optionally, the pulling assembly includes an inner cavity disposed within the C-shaped cage, one end of the winding shaft extending into the inner cavity is equipped with a winding wheel, a pull line is wound around the outside of the winding wheel, and one end of the pull line movably passes through the C-shaped cage and is fixedly connected to a pull ring.

[0009] Optionally, a guide ring is fixedly connected to the inner bottom wall of the cavity, and the guide ring is used for the winding shaft to move through.

[0010] Optionally, the inner walls on both sides of the opening are provided with limiting grooves, and a sliding rod is fixedly connected inside the limiting groove. The two ends of the sliding member are slidably assembled on the sliding rod, and a spring is movably sleeved on the sliding rod. The spring is located above the end of the sliding member.

[0011] Optionally, the two end side walls of the C-shaped cage are fixedly connected with clips, which are used for the pull rings to be hooked.

[0012] Optionally, the heating mechanism includes multiple hot air blowers assembled inside a C-shaped cage, the hot air blowers being arranged linearly at equal intervals inside the C-shaped cage, and the outside of the C-shaped cage being covered with an insulation film.

[0013] Optionally, the sliding mechanism includes a slide rail located at the bottom of the C-shaped cage, and the bottom of the C-shaped cage is provided with multiple pulleys, which are slidably fitted inside the slide rail.

[0014] On the other hand, this application provides a curing method for a curing device for concrete in cold regions, applied to the curing device for concrete in cold regions as described above, comprising the following steps: S1. Prepare a concrete component on the front side of the C-shaped cage, pull the pulling assembly, and drive the C-shaped cage to slide upward toward the sliding part on the side of the concrete component, so that the shielding cloth is stored in the cavity and the opening is exposed. S2. Slide the C-shaped cage, move the concrete component into the C-shaped cage through the opening, release the tensioning component to release the limit on the sliding component, let the sliding component slide down and reset, and drive the shielding cloth to extend out of the cavity to close the opening. S3. After the concrete component is placed inside the C-shaped cage, the heating mechanism of the C-shaped cage is activated to raise the temperature inside the cage and perform heat preservation and curing on the concrete component. S4. After the component is cured and formed, turn off the heating mechanism, open the opening, slide the C-shaped cage to remove the finished component, and at the same time prepare a new component at the opening on the other side. Repeat the operation to achieve simultaneous and efficient construction of pouring and curing.

[0015] Compared with the prior art, this application includes at least one of the following beneficial technical effects: This invention utilizes the combined structure of a C-shaped cage, a heating mechanism, a sealing mechanism, a pulling component, and a sliding mechanism. First, pulling the pulling component drives the sealing mechanism to retract the covering cloth and expose the opening. Then, the C-shaped cage slides into the concrete component on one side of the slide rail. Releasing the pulling component allows the covering cloth to close the opening. The heating mechanism is then activated to raise and maintain the temperature inside the cage, which is maintained by the insulation film to ensure normal cement hydration and resist low-temperature freezing damage. After the component is formed, the C-shaped cage slides out the finished component, and a new component is simultaneously prepared on the other side of the slide rail in a cyclical operation. This solves the problems of cumbersome and inefficient transportation in fixed insulated greenhouses. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example

[0024] like Figures 1 to 6 As shown, the present invention proposes a curing device for concrete in cold regions, comprising a C-shaped cage 1. Both ends of the C-shaped cage 1 have openings 11, and each opening 11 is equipped with a sealing mechanism to seal the openings 11. The sealing mechanism includes a cavity 13 within the C-shaped cage 1, which houses a shielding cloth 16 and a winding shaft 14. The winding shaft 14 is rotatably connected inside each cavity 13, and is used to wind and house the shielding cloth 16. A through groove 15 is provided at the bottom of each cavity 13. The shielding cloth 16 is wound and connected to the outside of the winding shaft 14, allowing the openings 11 to be closed or opened, thus sealing the cage. One end of the shielding cloth 16 movably passes through the through groove 15 and is fitted with a sliding member 17, which is slidably fitted within the opening 11.

[0025] The C-shaped cage 1 can be easily moved via a sliding mechanism, eliminating the need for manual handling of concrete components. Workers simply pull the ring 23 to expose the opening 11, sliding the C-shaped cage 1 next to the newly poured component for storage, thus reducing labor intensity and shortening handling time. The C-shaped cage 1 has openings 11 on both sides; one side is used to store already poured components for curing, while the other side allows for simultaneous pouring of new components. After curing, the working surface can be quickly switched by sliding the C-shaped cage 1, enabling parallel operation of curing and pouring, significantly improving construction efficiency.

[0026] Secondly, such as Figures 4 to 6 As shown, the C-shaped cage 1 has pull components at both ends corresponding to the sealing mechanism. These pull components are used to manually pull and drive the sealing mechanism to open. Each pull component includes an inner cavity 2 within the C-shaped cage 1. A winding wheel 21 is fitted to one end of the winding shaft 14 that extends into the inner cavity 2. The winding wheel 21 rotates as pulled by the pull line 22. The pull line 22 is wound around the outside of the winding wheel 21, and pulling the pull line 22 drives the winding wheel 21 and the winding shaft 14 to rotate. One end of the pull line 22 passes through the C-shaped cage 1 and is fixedly connected to a pull ring 23, which is used for manual pulling to control the sealing mechanism. Clips 261 are fixedly connected to the side walls at both ends of the C-shaped cage 1. These clips 261 are used to hold the pull ring 23 in the open state of the opening 11.

[0027] In addition, such as Figure 6 As shown, a guide ring 28 is fixedly connected to the inner bottom wall of the inner cavity 2. The guide ring 28 supports and guides the winding shaft 14 to ensure stable rotation. The guide ring 28 is used for the winding shaft 14 to move through.

[0028] It is worth noting that, such as Figure 5 As shown, both sides of the inner wall of the opening 11 are provided with limiting grooves 24, and each limiting groove 24 is fixedly connected with a sliding rod 25. The sliding rod 25 is used for sliding assembly of the sliding member 17 and serves as a guide. Both ends of the sliding member 17 are slidably assembled on the sliding rod 25, and each sliding rod 25 is movably sleeved with a spring 26. The spring 26 assists the sliding member 17 in resetting and drives the covering cloth 16 to close the opening 11. The springs 26 are all located above the ends of the sliding member 17.

[0029] Furthermore, such as Figure 2 As shown, a heating mechanism is installed inside the C-shaped cage 1. The heating mechanism includes several hot air blowers 27 assembled inside the C-shaped cage 1. The hot air blowers 27 are devices that heat the air and blow it out in a direction to provide clean and controllable hot air, thereby increasing and maintaining the curing temperature inside the cage. The hot air blowers 27 are arranged linearly and at equal intervals inside the C-shaped cage 1. The outside of the C-shaped cage 1 is covered with an insulation film 12. The insulation film 12 covers the outside of the C-shaped cage 1 to reduce heat loss and maintain the curing temperature inside the cage.

[0030] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the bottom of the C-shaped cage 1 is provided with a sliding mechanism, which is used to support the horizontal alternating sliding of the C-shaped cage 1. The sliding mechanism includes a slide rail 31 located at the bottom of the C-shaped cage 1, and multiple pulleys 3 are provided at the bottom of the C-shaped cage 1. The pulleys 3 cooperate with the slide rail 31 to realize the horizontal sliding of the cage. The pulleys 3 are slidably assembled in the slide rail 31.

[0031] This application provides a curing method for concrete curing devices in cold regions, such as... Figure 1 - Figure 6 As shown, it includes the following steps: S1. Prepare a concrete component on the front side of the C-shaped cage 1, pull the pulling component, and drive the C-shaped cage 1 to slide upward toward the sliding part 17 on the side of the concrete component, so that the shielding cloth 16 is stored in the cavity 13 and the opening 11 is exposed. S2. Slide the C-shaped cage 1, move the concrete component into the C-shaped cage 1 through the opening 11, release the tensioning component to release the limit on the sliding component 17, so that the sliding component 17 slides down to reset, and drives the shielding cloth 16 to extend out of the cavity 13 to close the opening 11. S3. After the concrete component is placed inside the C-shaped cage 1, the heating mechanism of the C-shaped cage 1 is activated to raise the temperature inside the cage and perform heat preservation and curing on the concrete component. S4. After the component is cured and formed, the heating mechanism is turned off, the opening 11 is opened, the C-shaped cage 1 is slid out to remove the finished component, and at the same time, a new component is prepared at the opening 11 on the other side. The operation is repeated to achieve simultaneous and efficient construction of pouring and curing.

[0032] In this embodiment, when using the curing device for concrete in cold regions, a concrete component is first prepared in front of the opening 11 on one side of the C-shaped cage 1; the pull ring 23 is pulled down to drive the pull wire 22 out from the winding wheel 21, so that the winding wheel 21 and the winding shaft 14 rotate under the limit of the guide support ring 28, and the shielding cloth 16 is rolled into the cavity 13; the sliding member 17 slides up along the sliding rod 25 and compresses the spring 26, and after the opening 11 is exposed, the pull ring 23 is fastened on the clip 261 to fix the opening in the open state.

[0033] Then push the C-shaped cage 1 so that the bottom pulley 3 slides smoothly along the slide rail 31, and move the prepared concrete component into the C-shaped cage 1 through the exposed opening 11; remove the clamp 261 and release the pull ring 23. Under the combined action of the spring force 26 and gravity, the sliding part 17 slides down quickly along the limiting groove 24 to reset, driving the shielding cloth 16 to be pulled out from the cavity 13 through the through groove 15, completely sealing the opening 11.

[0034] Next, the hot air blowers 27, which are arranged in an equally spaced array on the inner wall of the C-shaped cage 1, are started to continuously deliver hot air into the cage. Together with the insulation film 12 covering the outer layer of the C-shaped cage 1, a sealed insulation space is formed, which quickly raises and stabilizes the temperature inside the cage, providing a suitable environment for the concrete components, ensuring that the cement is fully hydrated, and avoiding low-temperature freezing damage.

[0035] Finally, after the concrete component has cured and formed, turn off the hot air blower 27; pull the pull ring 23 again to repeat the first step to expose the other side opening 11; slide the C-shaped cage 1 to move the cured component out of the cage; at the same time, a new concrete component can be prepared in front of the other side opening 11. Repeat the above steps to achieve parallel curing and pouring, and efficiently complete the concrete curing operation in cold regions.

[0036] The preferred embodiments of the present invention described above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
