Description

Technical Field

[0001] The present application relates to the field of concrete curing, and in particular to a concrete curing device. Background Art

[0002] Concrete curing takes the longest time in the entire concrete construction project, and it is also the construction operation that has the greatest impact on the quality of concrete. The reason why concrete can gradually harden and increase its strength is the result of cement hydration, and cement hydration requires certain temperature and humidity conditions. Therefore, concrete curing requires artificial creation of certain humidity and temperature conditions to allow the newly poured concrete to harden and increase its strength normally or accelerate its hardening and strength. In order to ensure the strength of concrete and prevent cracks from forming due to surface dryness, it is usually necessary to water and maintain the concrete to the necessary humidity. If the watering and maintenance of concrete is neglected, on the one hand, the strength of the concrete will be reduced, and on the other hand, the concrete will not have time to replenish water during the hardening process, resulting in a large lack of water, which will cause cracks.

[0003] In addition to humidity, temperature is also an important factor in the concrete curing process. If the temperature is too low, it will also affect the final quality of the concrete. When curing concrete in cold weather such as winter, there are mainly several methods such as film curing and greenhouse curing.

[0004] Film curing is to prevent the loss of water and heat by covering with a film. However, film curing can only play a role in heat preservation, but cannot control the temperature. If the outside temperature is low, the curing effect of this method will be greatly reduced. Secondly, although the film can prevent water from overflowing the film, it cannot prevent water from overflowing the concrete. If the temperature rises and the water overflows the concrete quickly, or if the film is not tightly wrapped during construction and causes water loss, the concrete surface may still appear dry. At this time, the film needs to be lifted for water replenishment, which will not only increase the workload, but may also cause the final quality of the concrete to vary greatly due to reasons such as untimely water replenishment or freezing of the concrete caused by lifting the film.

[0005] Greenhouse maintenance is achieved by building a greenhouse and installing electric heaters and other equipment in it to heat the air in the greenhouse to achieve concrete maintenance. However, this method requires uninterrupted heating, otherwise the air in the greenhouse will cool down in a very short time. And uninterrupted heating consumes a lot of energy. In addition, greenhouse maintenance also requires regular water spraying to ensure the humidity in the greenhouse. If cold water is sprayed directly, the cold water will fall directly on the concrete, which may cause structural damage to the concrete due to the large temperature difference between the inside and the outside. Therefore, before spraying water, the water needs to be heated, which further increases the maintenance cost. Summary of the invention

[0006] In order to solve the problems of high concrete curing cost and poor curing quality, the present application provides a concrete curing device.

[0007] The present application provides a concrete curing device that adopts the following technical solution: A concrete curing device comprises a circulation pipeline, a first water pump, a first heater, a spraying component and a plurality of curing components.

[0008] The curing assembly comprises a curing box and a first water tank. The curing box is used to accommodate concrete parts. The first water tank is arranged in the curing box.

[0009] The first heater is used to heat water in at least one of the first water tanks.

[0010] The plurality of first water tanks are all connected through the circulation pipeline, and the first water pump is arranged on the circulation pipeline.

[0011] The spray assembly is communicated with the curing box and is used for spraying water into the curing box.

[0012] By adopting the above technical solution, efficient and uniform maintenance of multiple concrete parts can be achieved. Specifically: The arrangement of the circulation pipeline, the first water pump and the plurality of first water tanks enables water to circulate between the first water tanks, thereby ensuring the consistency and stability of the water temperature, making the temperature in each curing box substantially consistent, and ensuring the stability of the curing quality of the concrete parts.

[0013] The first heater can heat the water in at least one first water tank, and then transfer the heat to other first water tanks through the circulation system. Even if there is only one first heater, the water in multiple first water tanks can be evenly heated, and the heating speed will not be too fast, avoiding excessive heating.

[0014] The connection design between the spray assembly and the curing box enables the spray assembly to spray water into the curing box to keep the surface of the concrete parts moist, which is beneficial to improving the strength and durability of the concrete.

[0015] The design of multiple curing components enables the device to cure multiple concrete parts at the same time, thereby improving the curing efficiency.

[0016] Preferably, the spray assembly includes a second water tank, a water supply pipe, a second water pump, a spray head, a water spray pipe, a first valve and a second valve.

[0017] The spray head is arranged in the maintenance box and is connected with the first water tank through the water spray pipe. The first valve is arranged on the water spray pipe.

[0018] The second water tank is in communication with the circulation pipeline through the water supply pipeline, and the second water pump and the second valve are both arranged on the water supply pipeline.

[0019] By adopting the above solution, the second water pump can guide the water in the second water tank into the circulation pipe, so that the water in the first water tank is sprayed out through the nozzle, improving the humidity in the curing box. And because there is a large amount of hot water in the first water tank, when the amount of water sprayed is not large, there is no need to heat the water in the second water tank. The cold water in the second water tank can be directly guided into the circulation pipe, so that the nozzle can spray hot water without causing a large fluctuation in the temperature in the first water tank.

[0020] Preferably, the concrete curing device further comprises a second heater, and the second heater is used for heating the water in the second water tank.

[0021] By adopting the above technical solution, the water temperature in the second water tank can be effectively increased, ensuring that the water temperature sprayed by the spray assembly into the curing box reaches an appropriate temperature range, further improving the curing effect of the concrete parts.

[0022] Preferably, the water spray pipe is at least partially a bendable pipe.

[0023] By adopting the above technical solution, the water spray pipe is at least partially a bendable pipe, so that the nozzle can flexibly adjust the water spray direction and position, thereby improving the maintenance effect.

[0024] Preferably, the first water tank comprises a first part and a second part which are interconnected.

[0025] There are two first water tanks in the curing box, the first parts of the two first water tanks are respectively located on opposite sides of the concrete component in a first direction, the second parts of the two first water tanks are respectively located on opposite sides of the concrete component in a second direction, and the first direction is perpendicular to the second direction.

[0026] By adopting the above technical solution, the layout of the first water tank enables the water in the first water tank to be evenly distributed around the concrete component, ensuring that all parts of the concrete component can receive a balanced insulation or heating effect, avoiding the phenomenon of excessive moisture or dryness in some areas due to uneven temperature, and improving the maintenance quality.

[0027] Preferably, the concrete curing device further comprises a heat insulating pad, which is arranged in the curing box and located above the concrete component.

[0028] By adopting the above technical solution, the thermal insulation pad can prevent heat loss in the curing box and reduce the heating frequency of the first heater.

[0029] Preferably, a support frame is provided on the inner wall of the curing box, and a limiting member is provided on the support frame.

[0030] The thermal insulation pad is provided with a limiting portion, and the limiting member is in limiting cooperation with the limiting portion.

[0031] By adopting the above technical solution, the setting of the support frame and the limiter can ensure the stable fixation of the thermal insulation pad in the curing box, prevent the thermal insulation pad from shifting during use, thereby ensuring uniform heating of the concrete parts and improving the curing effect. At the same time, the matching design of the limiter and the limiter makes the installation and replacement of the thermal insulation pad more convenient and quick.

[0032] Preferably, the curing box comprises a box body and an upper cover.

[0033] The upper cover is used to cover the top of the box body, so that the thermal insulation pad is clamped between the upper cover and the support frame.

[0034] By adopting the above technical solution, the structural design of the upper cover and the box body enables the insulation pad to be firmly clamped between the upper cover and the support frame, effectively preventing the insulation pad from shifting or falling off during the curing process, ensuring the stability and reliability of the insulation effect, and thereby improving the quality and efficiency of concrete curing.

[0035] Preferably, the concrete curing device further comprises heat dissipation fins, and the heat dissipation fins are arranged on the first water tank.

[0036] By adopting the above technical solution, the heat dissipation fins are arranged in the first water tank, which can effectively increase the heat exchange area between the first water tank and the environment outside the first box body, improve the heat transfer efficiency, thereby accelerating the temperature adjustment speed in the curing box, ensuring that the concrete parts always maintain a suitable temperature during the curing process, and improving the curing quality and efficiency.

[0037] Preferably, a humidity sensor and a first temperature sensor are provided in the curing box.

[0038] By adopting the above technical solution, the humidity and temperature in the curing box can be monitored in real time to ensure that the concrete parts are in suitable environmental conditions during the curing process, thereby improving the curing quality. The humidity sensor can detect the humidity in the curing box in real time to ensure that the humidity is maintained within the set range and avoid degradation of concrete performance due to over-wetness or over-dryness.

[0039] The first temperature sensor can detect the temperature in the curing box in real time to ensure that the temperature is maintained within an appropriate range and prevent the temperature from being too high or too low to affect the quality of the concrete.

[0040] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the combined use of the circulation pipe, the first water pump and the first heater, water circulation between multiple curing components is achieved, ensuring that the temperature in each curing box remains consistent, thereby improving the quality stability of concrete curing; 2. The setting of the spray component allows the curing box to continuously replenish water, avoiding the problem of frequent water addition in traditional curing methods, simplifying the operation process and improving the curing efficiency; 3. The second water tank is connected to the circulation pipe through the water supply pipe, so that when the second water pump is started, the nozzle can immediately spray out hot water with a temperature basically the same as that in the curing tank.

[0047] The following is combined with Figure 1 —5 Provide further details of this application.

[0048] like Figure 1 to Figure 2 As shown, an embodiment of the present application discloses a concrete curing device, including a circulation pipeline 1, a first water pump 2, a first heater, a spraying assembly 3 and a plurality of curing assemblies 4.

[0049] The curing assembly 4 includes a curing box 41 and a first water tank 42. The curing box 41 is used to accommodate the concrete component 200, and the first water tank 42 is arranged in the curing box 41; the first heater is used to heat the water in at least one first water tank 42; multiple first water tanks 42 are connected through a circulation pipe 1, and the first water pump 2 is arranged on the circulation pipe 1; the spray assembly 3 is connected to the curing box 41 and is used to spray water into the curing box 41.

[0050] Specifically, the outer sides of the curing box 41 and the circulation pipe 1 are wrapped with an insulation layer, which can be made of a material such as sponge. An observation window is provided on the side wall of the curing box 41, and an opening corresponding to the observation window is provided on the insulation layer outside the curing box 41. An insulation curtain is provided at the opening, and the insulation curtain and the insulation layer can be connected by a zipper. When it is necessary to observe the curing status of the concrete component 200, just unzip the zipper, open the insulation curtain, and observe the concrete component 200 through the observation window.

[0051] The first heater may be a heating rod, a heating wire or other conventional heating devices. At least one first water tank 42 is provided with a first heater, and the first heater can heat the water in the corresponding first water tank 42 .

[0052] The first water pump 2 can drive water to circulate in the circulation pipe 1 and the plurality of first water tanks 42, so that the temperature in the plurality of first water tanks 42 tends to be consistent. The first water tank 42 can be made of a material with good thermal conductivity such as aluminum alloy, and the first water tank 42 is provided with heat dissipation fins, so that the heat of the water in the first water tank 42 can be dissipated to the outside, thereby heating and insulating the concrete member 200 in the curing box 41, and, compared with spraying hot water for insulation, the solution of the embodiment of the present application does not change the humidity in the curing box 41 during heating.

[0053] The first water tank 42 is provided with a water inlet and a water outlet for connecting to the circulation pipe 1. The water inlet can be arranged at the bottom of the side wall of the first water tank 42, and the water outlet can be arranged at the upper half of the side wall of the first water tank 42. Hot water flows in from the bottom and flows out from the top, which can ensure that the temperature of each area of ​​the first water tank 42 is basically the same, and the flowing water has a faster heat exchange speed, which is convenient for heat dissipation to the outside, and improves the insulation effect of the concrete component 200.

[0054] By driving the water to circulate, the temperature in each curing box 41 can be made substantially uniform, which helps to improve the stability of curing of the concrete member 200 and avoid uneven quality. In addition, compared with air, the temperature of water changes slowly and has a larger specific heat capacity, so that the water in the first water tank 42 does not need to be heated continuously, but only needs to be heated intermittently, so that the temperature in each curing box 41 can always be kept within a suitable range, which helps to save resources.

[0055] In addition, the first heater and the first water pump 2 are matched with each other, so that only a single first heater can heat the water in all the first water tanks 42 at the same time. Since the total amount of water in the multiple first water tanks 42 is large, even if a high-power first heater is used, the water temperature in the first water tank 42 will not rise too fast, which is convenient for fine adjustment of the temperature in the curing tank 41, and there is no need to use multiple low-power first heaters to heat the water in the multiple first water tanks 42 respectively in order to avoid too fast temperature rise.

[0056] like Figure 1 to Figure 2 As shown, the spray assembly 3 includes a second water tank 31 , a water supply pipe 32 , a second water pump 33 , a spray head 34 , a water spray pipe 35 , a first valve 36 and a second valve 37 .

[0057] The nozzle 34 is arranged in the maintenance box 41 and is connected to the first water tank 42 through the water spray pipe 35. The first valve 36 is arranged on the water spray pipe 35. The second water tank 31 is connected to the circulation pipe 1 through the water supply pipe 32. The second water pump 33 and the second valve 37 are both arranged on the water supply pipe 32.

[0058] Specifically, both the first valve 36 and the second valve 37 can be solenoid valves. A humidity sensor and a first temperature sensor are provided in the curing box 41 to monitor the temperature and humidity in the curing box 41. When the humidity in the curing box 41 reaches the humidity requirement of the concrete member 200, the first valve 36 and the second valve 37 are both closed.

[0059] When the humidity in the curing box 41 is low, the first valve 36 and the second valve 37 are opened, and the second water pump 33 introduces the water in the second water tank 31 into the circulation pipe 1 through the water supply pipe 32, so that the pressure in the first water tank 42 increases, and the water in the first water tank 42 is sprayed out through the nozzle 34, thereby increasing the humidity in the curing box 41.

[0060] The nozzle 34 can be specifically an atomizing nozzle 34, and the water mist sprayed by the nozzle can be dispersed in the entire curing box 41, so that all parts of the concrete component 200 are effectively moistened. Furthermore, at least part of the water spray pipe 35 is a bendable pipe. For example, the water spray pipe 35 can be a combination of a rigid pipe and a bendable pipe. The setting of the bendable pipe makes the position and water spray direction of the nozzle 34 flexible and adjustable, further ensuring that all parts of the concrete component 200 are effectively moistened.

[0061] Compared with directly introducing the water in the second water tank 31 through the water supply pipe 32 to the nozzle 34 and spraying it into the curing tank 41, the embodiment of the present application introduces the water in the second water tank 31 into the circulation pipe 1 and the first water tank 42 first, so that the water in the first water tank 42 is sprayed out through the nozzle 34, so that the water sprayed out from the nozzle 34 is hot water from the beginning, avoiding affecting the temperature in the curing tank 41. Even if the water in the second water tank 31 is heated first, then introduced into the nozzle 34 through the water supply pipe 32 and the water in the second water tank 31 is directly sprayed out, the technical effect of the embodiment of the present application cannot be achieved, because: 1. There is cold water in the water supply pipe 32. Even if the water in the second water tank 31 is hot water, when the water in the second water tank 31 flows into the nozzle 34 through the water supply pipe 32 and is sprayed out, the first water to flow out is still cold water.

[0062] 2. The curing box 41 is frequently sprayed and replenished with water. Before each spraying, it is necessary to wait for the second heater to heat the water in the second water tank 31, resulting in a waste of time. If the water in the second water tank 31 is heated and kept warm in advance, energy consumption will increase.

[0063] The solution of the embodiment of the present application can achieve that even if the water in the second water tank 31 is cold water, the water finally sprayed out by the nozzle 34 is still hot water, without waiting for the water heating process, and without heating and keeping the water in the second water tank 31 in advance. Since the amount of water sprayed each time is very small compared to the total amount of water in the first water tank 42, the second water pump 33 only needs to introduce a small amount of cold water in the second water tank 31 into the circulation pipe 1 to meet the spraying demand, and the small amount of cold water introduced will not have a significant impact on the temperature in the first water tank 42.

[0064] Furthermore, the concrete curing device further includes a second heater, and the second heater is used to heat the water in the second water tank 31 .

[0065] Specifically, the second heater may also be a heating device such as a heating rod. By providing the second heater, the water temperature in the second water tank 31 can be quickly increased in the preparation stage before maintenance, and the hot water in the second water tank 31 is introduced into the first water tank 42 through the second water pump 33, thereby replenishing the water volume in the first water tank 42 and increasing the temperature in the first water tank 42. The first heater and the second heater can work together to quickly increase the temperature in the first water tank 42 and shorten the maintenance preparation time.

[0066] In addition, when the amount of spray water in the curing tank 41 is large, the water in the second water tank 31 can be heated by the second heater to a temperature close to or the same as that in the first water tank 42, and then the water in the second water tank 31 is introduced into the circulation pipe 1 to avoid large fluctuations in the water temperature in the first water tank 42. A second temperature sensor is provided in the first water tank 42, and a third temperature sensor is provided in the second water tank 31 to monitor the water temperatures in the first water tank 42 and the second water tank 31.

[0067] like Figure 3 As shown, the concrete curing device further includes a heat insulating pad 5 , which is arranged in the curing box 41 and located above the concrete component 200 .

[0068] Specifically, the maintenance box 41 includes a box body 411 and an upper cover 412 . The upper cover 412 is hinged to the top of the box body 411 , and the upper cover 412 can be turned over to cover the top of the box body 411 .

[0069] A support frame 413 is provided on the inner wall of the box body 411 of the curing box 41. The support frame 413 may be annular and connected to each inner wall of the box body 411. A stopper 414 is provided on the top of the support frame 413. The thermal insulation pad 5 has a stopper portion. The stopper 414 cooperates with the stopper portion to fix the thermal insulation pad 5. For example, the stopper 414 may be a stopper rod, and the stopper portion may be a stopper hole. The stopper rod is passed through the stopper hole to fix the thermal insulation pad 5.

[0070] Furthermore, when the upper cover 412 is placed on the top of the box body 411, the upper cover 412 can press on the thermal insulation pad 5, so that the thermal insulation pad 5 is clamped between the upper cover 412 and the support frame 413, further improving the thermal insulation effect and preventing the heat loss in the curing box 41. The thermal insulation pad 5 can be a quilt.

[0071] The first water tank 42 may be a cubic structure. There are two first water tanks 42 in the curing box 41, and the two first water tanks 42 are respectively located on opposite sides of the concrete member 200 in the first direction. The two first water tanks 42 are used to simultaneously heat the interior of the curing box 41, thereby improving the heating efficiency. The cubic structure of the first water tank 42 is easy to manufacture.

[0072] like Figures 4 to 5As shown, in other embodiments, the first water tank 42 includes a first part 421 and a second part 422 that are interconnected. There are two first water tanks 42 in the curing box 41, and the first parts 421 of the two first water tanks 42 are respectively located on opposite sides of the concrete member 200 in the first direction, and the second parts 422 of the two first water tanks 42 are respectively located on opposite sides of the concrete member 200 in the second direction, and the first direction is perpendicular to the second direction. Through the two first water tanks 42, heat can be transferred to the opposite sides of the concrete member 200 in the first direction and the opposite sides in the second direction at the same time, so that the temperature of each area in the curing box 41 is more uniform, which helps to improve the curing effect.
