Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a concrete curing device and method for concrete preparation. Background Technology

[0002] After concrete is poured, there is a relatively long setting period, generally 10-30 days. If the external environment is hot and the air is dry, the water in the concrete will evaporate too quickly, causing dehydration. This prevents the cement particles, which have already formed a gel, from fully hydrating and transforming into stable crystals, resulting in insufficient bonding strength and causing flaking or powdering on the concrete surface. Simultaneously, if the external temperature is low, the concrete slab will not set quickly enough, reducing the cement's hydration rate and affecting the development of the material's strength, as well as the efficiency of the preparation process. Premature evaporation of water before the concrete has reached sufficient strength can also cause significant shrinkage deformation, leading to drying shrinkage cracks. Therefore, the initial curing stage after concrete pouring is crucial. Curing should begin immediately after the concrete has set, and dry-hard concrete should be cured immediately after pouring.

[0003] Currently, the most common type of curing is natural curing. However, watering and laying straw mats or felts in natural curing are mostly done manually, which is frequent and labor-intensive. This results in many concrete surfaces not being properly moisturized, and manual watering also leads to serious waste of water resources. Therefore, there is a need for a concrete curing device and curing method for concrete preparation to solve the above problems. Summary of the Invention

The two ends of the rotating rollers are rotatably connected to the water-holding block through end heads. The rotating rollers and the end heads are hollow and respectively connected to the water-holding groove.

[0011] Preferably, the rotating roller is composed of two semi-circular arc plates spliced ​​together, one of which is made of copper, aluminum or iron, and the other is made of hard resin.

[0012] Preferably, the third maintenance component includes two fixing strips and several chains.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] It should be noted that, in order to make the above-mentioned objectives, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Depend on Figure 1 The concrete curing device for concrete preparation shown includes a support plate 1. A frame assembly is fixedly connected to the top surface of the support plate 1. Two supports 5 are symmetrically fixedly connected to the top of the frame assembly. A water spraying assembly is fixedly connected between the two supports 5. A forming mechanism is fixedly connected to the inner cavity of the frame assembly. The forming mechanism includes two first curing components symmetrically fixedly connected to the inner cavity of the frame assembly. A push plate 27 and a baffle 28 are respectively arranged between the two first curing components. A drive motor 29 is drivenly connected to the push plate 27. The drive motor 29 is fixedly connected to the frame assembly. A concrete slab 7 is arranged in the enclosed area between the first curing components and the push plate 27 and the baffle 28. A second curing component is arranged on the bottom surface of the concrete slab 7 and the bottom surface of the forming mechanism. The second curing component is connected to the frame assembly. A third curing component is arranged on the top surface of the concrete slab 7. The third curing component is fixedly connected to the two supports 5 respectively.

[0036] Furthermore, the drive unit 29 is a hydraulic cylinder or an electric cylinder, which can push the push plate 27 to drive the molding mechanism and the concrete slab 7 to move back and forth. This is existing technology and will not be described in detail here.

[0037] The present invention uses a frame assembly to fix the molding mechanism, thereby strengthening the pressure-bearing strength of the molding mechanism. Concrete is poured inside the molding mechanism to directly form the concrete slab 7. The first curing assembly, the second curing assembly, and the third curing assembly respectively perform curing measures such as adding water and heat preservation on the concrete slab 7, thereby improving the molding quality of the concrete slab 7.

[0038] Further optimization of the design involves a frame component comprising two water-holding blocks 2. Each water-holding block 2 has a water-holding trough 3 on its top surface, which holds water for curing the concrete slab 7. An installation block 4 is fixedly connected to one end of each water-holding block 2. The installation block 4 is fixedly connected to a drive motor 29, and the output shaft of the drive motor 29 passes through the installation block 4 and is fixedly connected to a push plate 27. The output shaft of the drive motor 29 is also slidably connected to the installation block 4. The opposite sides of the two water-holding blocks 2 are fixedly connected to two first curing components. The water-holding blocks 2 and the installation block 4 are fixedly connected to the top surface of the support plate 1. This connection between the installation block 4, the water-holding blocks 2, and the support plate 1 completes the enclosure and fixation of the molding mechanism, improving its stability.

[0039] Furthermore, the water in the water tank 3 is fixedly connected to and communicated with the external solar energy device to heat it, thereby improving the solidification environment of the concrete slab 7 when the outside temperature is low.

[0040] Depend on Figure 2-5 As shown, the first maintenance component includes an airbag 8, which is fixedly connected to and connected to a valve 13. The airbag 8 can be inflated or filled with water using the valve 13, thus completing the airbag's contraction and expansion. The airbag 8 slides in contact with the side of the water-filled block 2. The airbag 8 is fixedly connected to and connected to a side panel 9, which has several water inlet holes. These water inlet holes connect the inner cavity of the airbag 8 to the concrete slab 7, allowing the water filled into the airbag 8 to come into contact with the concrete slab 7. A plug 10 is slidably connected inside the water inlet hole. A rubber plate 11 is fixedly connected to the plug 10. Two rubber plates 11 are provided, facing each other. A fixing plate 12 is fixedly connected to one side of each rubber plate 11. The fixing plate 12 is fixedly installed in the middle of the side of the side panel 9. The fixing plate 12 is fixedly connected to one side of the rubber plate 11, restricting the direction of water absorption and expansion of the rubber plate 11. The expanded rubber plate 11 can pull the plug 10 out of the water inlet hole, allowing water to contact the concrete slab 7. The fixing plate 12 and rubber plate 11 are both located inside the airbag 8. A heating rod 14 is fixedly installed on the side of the fixing plate 12 away from the side panel 9. The two side panels 9 are detachably connected to a push plate 27 and a baffle 28, respectively. The push plate 27 and baffle 28 are preferably fixed to the two side panels 9 with screws for easy removal. The outer surface of the concrete slab 7 is in contact with the two side panels 9, the baffle 28, and the push plate 27. The rubber sheet 11 is made of water-absorbing and swellable rubber, and the fixing plate 12 is made of flexible resin. The fixing plate 12 can withstand the deformation caused by the water-absorbing and swellable rubber sheet 11.

[0041] Furthermore, the airbag 8 is connected to an external inflator and water pump, which is existing technology and will not be described in detail here.

[0042] Furthermore, the plunger 10 is made of flexible rubber or silicone material, which facilitates the pulling out of the rubber plate 11.

[0043] Depend on Figure 2 , 7 As shown, the second curing component includes an abutment plate 15. The top surface of the abutment plate 15 is slidably connected to the side panel 9, the push plate 27, and the baffle 28. The top surface of the abutment plate 15 has several rotating grooves, and several rotating rollers 16 are rotatably connected in the rotating grooves. The two ends of the rotating rollers 16 are rotatably connected to the water-holding block 2 through end heads 17. The rotating rollers 16 and end heads 17 are hollow and connected to the water-holding tank 3. The rotating rollers 16 are spliced ​​together from two arc plates with a semi-circular cross-section. One arc plate is made of copper, aluminum, or iron, and the other arc plate is made of hard resin. The rotating rollers 16 can rotate to allow the sides of the different materials to contact the bottom surface of the concrete slab 7. By utilizing the different thermal conductivity coefficients of the different materials, heat dissipation or heat preservation of the bottom surface of the concrete slab 7 can be achieved.

[0044] Furthermore, the bottom surface of the concrete slab 7 is adapted to the abutment plate 15 and the rotating roller 16 respectively, and the concrete slab 7 is placed on the top surface of the abutment plate 15.

[0045] Depend on Figure 6 As shown, the third curing component includes two fixing bars 18 and several chains 19. The two fixing bars 18 are detachably connected to the top surface of the push plate 27 and the top surface of the baffle 28, respectively. A cover 20 is fixedly connected between the two fixing bars 18. The fixing bars 18 and the cover 20 are respectively connected to a winding assembly via the chains 19. The cover 20 can be lifted a certain distance by the winding assembly to achieve different degrees of heat dissipation or humidity reduction for the concrete slab 7. The winding assembly includes a motor 21 and a reel 22. The motor 21 is fixedly connected to two supports 5 via a crossbeam 6, and the motor 21 is fixedly connected to the reel 22. The chains 19 are wound around the outer side of the reel 22.

[0046] Furthermore, the covering 20 is a straw mat or tarpaulin, which can achieve intermittent contact with the concrete slab 7 when pulled by the chain 19.

[0047] In a further optimized design, absorbent cotton cloth 23 is fixedly connected to both sides of the cover 20. One end of the absorbent cotton cloth 23 is set on the bottom surface of the cover 20, and the other end is set in the inner cavity of the water tank 3. The absorbent cotton cloth 23 can absorb the water in the water tank 3 to the top surface of the concrete slab 7 at the other end, thereby replenishing the concrete slab 7 with water.

[0048] Depend on Figure 6 As shown, the sprinkler assembly includes a fixed frame 24, which is fixedly connected to the crossbeam 6. Several nozzles 25 are fixedly connected to both ends of the bottom surface of the fixed frame 24. The nozzles 25 are fixedly connected to and connected to a water pump. The water pump is located in the inner cavity of the water tank 3. The water pump can spray the water in the water tank 3 through the nozzles 25 onto the top surface of the concrete slab 7, thereby achieving strong water replenishment to the concrete slab 7.

[0049] Furthermore, the water pump and the nozzle 25 are fixedly connected and linked by a pipe, which is existing technology and is not shown in the attached drawings.

[0050] To further optimize the design, limit blocks 26 are also provided at both ends of the airbag 8. The opposite sides of the limit blocks 26 slide in contact with the water block 2 and the side panel 9, respectively. The limit blocks 26 can prevent the push plate 27 and the baffle 28 from bearing too much force when the airbag 8 contracts, which would cause the concrete slab 7 to not be properly secured.

[0051] A method for curing concrete used in concrete preparation includes the following steps:

[0052] S1. Molding: Concrete is introduced into the enclosed area between the first curing component and the push plate 27 and the baffle 28, and solidified to form concrete slab 7.

[0053] Inflation is pumped into the airbag 8 via valve 13 to provide lateral support for the side panel 9, preventing it from deflecting due to its excessive length and affecting the molding quality of the concrete slab 7. Meanwhile, concrete is injected into the box-like structure formed by the side panel 9, push plate 27, baffle 28, and abutment plate 15. After one end has solidified, the concrete absorbs water and releases heat during the solidification process. Water is then sprayed onto the top surface of the concrete slab 7 through the nozzle 25 at the top to replenish moisture and cool it.

[0054] Furthermore, in order to further reduce the solidification heat of the concrete slab 7 during the process, the drive motor 29 is started. The drive motor 29 extends its output shaft to push the push plate 27 fixed thereon, thereby driving the entire molding mechanism to move the concrete slab 7, so that the metal side of the rotating roller 16 comes into contact with the concrete slab 7, and the metal side of the rotating roller 16 comes into contact with the clean water flowing inside the rotating roller 16 to achieve heat exchange.

[0055] If the outside temperature is low, the clean water in the water tank 3 can be connected to an external solar or other energy heater to heat the water in the water tank 3, thereby maintaining the solidification temperature of the concrete slab 7. The heating rod 14 in the airbag 8 heats the concrete slab 7 from all directions.

[0056] S2. Humidification and protection: Clean water is injected into the first curing component to achieve humidification and curing of the concrete slab 7; at the same time, the second curing component switches different positions of the concrete slab 7 through the drive motor 29, and the third curing component maintains the temperature and humidity of the concrete slab 7 by adjusting the contact area with the concrete slab 7.

[0057] To ensure consistent setting rates on the sides and top of the concrete slab 7, gas is released from the airbag 8 and a large amount of clean water is injected. The clean water comes into contact with the water-absorbing and expanding rubber sheet 11, causing it to expand and deform. Due to the tension of the fixing plate 12, the deformation of the rubber sheet 11 causes the plug 10 to detach from the water inlet hole, allowing clean water to come into contact with the sides of the concrete slab 7 from the water inlet hole. Furthermore, as the concrete slab 7 solidifies and the gaps created between it and the side panel 9, the clean water achieves complete contact with the sides of the concrete slab 7. Further, as the clean water continues to seep in, it will also contact the concrete slab 7 through the gap between it and the top surface of the abutment plate 15, thus achieving complete water replenishment of the concrete slab 7.

[0058] Covering element 20 covers the top surface of concrete slab 7, preventing significant moisture evaporation. Furthermore, the gap between covering element 20 and the top surface of concrete slab 7 can be adjusted via the chain 19, allowing for coverage of different areas of the concrete slab 7. This enables flexible adjustment of the setting rate and effect of the concrete slab 7. To reduce the frequency of manual operation, absorbent cotton cloth 23 is fixed to both sides of covering element 20, continuously drawing water from the water tank 3 onto the top surface of concrete slab 7, thus avoiding frequent activation of the water spraying system.

[0059] S3. Process adjustment: Concrete slab 7 has a large water absorption capacity, so increase the contact area between the third curing component and concrete slab 7, and simultaneously turn on the water spray component.

[0060] If the concrete slab 7 requires a large amount of water, the first curing component and the water spraying component are turned on at the same time to replenish the concrete slab 7 with water. The motor 21 is used to make the cover 20 fit as closely as possible to the top surface of the concrete slab 7. The cover 20 can absorb a large amount of clean water to make up for the needs of the concrete slab 7.

[0061] S4. Curing complete: After the concrete slab 7 has completely solidified, remove the first curing component and baffle 28, and start the drive motor 29 to push the concrete slab 7 out of the frame component.

[0062] After the curing of concrete slab 7 is completed, first remove the limiting block 26, release the air bladder 8, and remove the first curing component and baffle 28. Then start the drive motor 29 to push the push plate 27 to push the concrete slab 7 out of the frame component, thus completing the curing of concrete slab 7.

[0063] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
