Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to an automatic spray curing device for large-volume concrete walls. Background Technology

[0002] Curing of cast-in-place concrete is a crucial step in ensuring normal strength development, preventing cracking, and guaranteeing durability and overall quality. The core of curing is controlling the temperature and humidity of the concrete to allow it to undergo hydration reactions under suitable conditions.

[0003] Chinese patent CN219344099U discloses an automatic spray curing device based on temperature and humidity control, which includes a wall and a fixed plate located on the top of the wall. A mixing tank, a heating tank and a water inlet tank are installed on the top of the fixed plate. One side of the water inlet tank is connected to the mixing tank through a water inlet pipe. A water inlet is provided at the connection between the heating tank and the mixing tank. An adjustment mechanism is installed inside the mixing tank to adjust the flow rate of the water inlet pipe and the water inlet. A spraying mechanism is installed at the bottom of the fixed plate to spray and cure the side of the wall.

[0004] The spray curing device in the relevant technology can adjust the water temperature according to the temperature of the concrete wall surface to achieve wall curing. However, for large-volume concrete walls, due to the thickness of the wall, it is impossible to monitor the internal temperature changes of the wall. Therefore, the structural strength of the wall may be affected after curing, which needs to be improved. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic spray curing device for large-volume concrete walls, which can ensure the structural strength of the wall.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic spray curing device for large-volume concrete walls, comprising: Temperature sensors are embedded in the wall in layers, with multiple sensors spaced apart in each layer. A wireless temperature sensor is connected to the temperature sensor. A temperature-controlled water tank includes a cold water tank, a hot water tank, a warm water tank, and a control platform. The cold water tank and the hot water tank are both connected to the warm water tank via water pumps. The control platform is connected to the wireless temperature acquisition device and is used to control the opening and closing of a pair of water pumps. A water supply pipe is connected to the warm water tank via a high-pressure pump, and the high-pressure pump is connected to the control platform. The sprinkler pipes are horizontally and layered on the wall surface. Multiple nozzles facing the wall surface are spaced apart on the sprinkler pipes. The sprinkler pipes are connected to the water supply pipes via solenoid valves, and the solenoid valves are connected to the control platform.

[0007] In a preferred embodiment, the present invention can be further configured such that: multiple clamps are spaced apart on the spray pipe, and the clamps are connected to tie bolts on the wall.

[0008] In a preferred embodiment, the present invention can be further configured such that a protective cover is provided between two adjacent spray pipes.

[0009] In a preferred embodiment, the present invention can be further configured such that: multiple locking rings are provided at both the upper and lower ends of the protective cover, and the locking rings hook the spray pipe.

[0010] In a preferred embodiment, the present invention can be further configured such that the temperature-controlled water tank also includes a base, the lower end face of which is provided with casters, and the base is used to place the cold water tank, hot water tank, warm water tank and control platform.

[0012] In a preferred embodiment, the present invention can be further configured such that: the spray pipe includes multiple connecting pipes and a tee head, the connecting pipes are threaded to two of the interfaces of the tee head, and the spray head is threaded to the other interface of the tee head.

[0013] In summary, this utility model has the following beneficial effects: 1.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, an automatic spray curing device for large-volume concrete walls includes a temperature sensor 1, a wireless temperature collector 2, a temperature-controlled water tank 3, a water supply pipe 4, and a spray pipe 5.

[0018] like Figure 1 As shown, temperature sensors 1 are pre-embedded in layers inside the wall, with multiple sensors spaced apart in each layer, and the embedding depth of the multiple temperature sensors 1 gradually increases. Temperature sensors 1 are wireless with IP68 protection rating, and their minimum monitoring distance can reach 0.5 meters, supporting a wide measurement range of -20℃ to 150℃. Wireless temperature acquisition device 2 connects to temperature sensors 1 and can continuously measure and record temperature data at each measuring point according to a preset sampling frequency.

[0019] like Figure 1 , Figure 2 As shown, the temperature-controlled water tank 3 includes a base 31, a cold water tank 32, a hot water tank 33, a warm water tank 34, and a control platform 35. The base 31 is equipped with casters 36 on its lower surface, allowing it to move freely on the ground. The cold water tank 32, hot water tank 33, warm water tank 34, and control platform 35 are all mounted on the base 31. The cold water tank 32 and hot water tank 33 are both connected to the warm water tank 34 via water pumps. The control platform 35 is connected to the wireless temperature sensor 2 and is used to control the start and stop of a pair of water pumps.

[0020] like Figure 1 , Figure 3As shown, the water supply pipe 4 is connected to the warm water tank 34 via a high-pressure pump 51, and the high-pressure pump 51 is connected to the control platform 35. The spray pipes 5 are horizontally and layered on the wall surface, and the layering of the spray pipes 5 is the same as that of the temperature sensor 1. Multiple nozzles 52 facing the wall surface are spaced apart on the spray pipes 5. The spray pipes 5 are connected to the water supply pipe 4 via a solenoid valve 53, and the solenoid valve 53 is connected to the control platform 35.

[0021] During construction, since the wall needs to be poured in layers, temperature sensors 1 for each layer are installed inside the wall before each pour, and then poured into the concrete wall to achieve temperature measurement at different depths.

[0022] When wall maintenance is required, temperature sensor 1 collects temperature data every 15 minutes with an accuracy of ±0.5℃, and then the data is collected to wireless temperature collector 2, which then records and transmits the data to control platform 35.

[0023] The control platform 35 pre-sets the curing cycle, which is 4 hours each time. At the same time, it adjusts the curing cycle and curing water temperature according to the preset threshold, which is the temperature difference between the inside and surface of the concrete ≥20℃ or the temperature difference between the surface and the ambient temperature ≥18℃.

[0024] During maintenance, the cold water tank 32 is filled with tap water, and the hot water tank 33 is equipped with a heater. The water temperature is always maintained between 50 and 90°C. Heating begins when the water temperature in the hot water tank 33 is below 50°C and stops when the water temperature reaches 90°C. Precise temperature control is not required.

[0025] At the start of maintenance, based on the received information, the water pumps are controlled to start and stop, drawing water from the cold water tank 32 and the hot water tank 33 into the warm water tank 34. By controlling the pumping volume of the two water pumps, the water temperature in the warm water tank 34 is regulated to meet the spraying requirements.

[0026] Finally, the control platform 35 will control the high-pressure pump 51 and the solenoid valve 53 to open and close, and control the opening and closing of each layer of spray pipe 5 as needed to complete the layered curing of the wall.

[0027] Therefore, by setting up multiple layers of temperature sensors 1 embedded inside the wall, the temperature difference between the inner and outer surfaces of the concrete wall, the cooling rate, and changes in ambient temperature can be transmitted to the control platform 35. Then, the outlet water temperature of the warm water tank 34 can be adjusted. At the same time, in conjunction with the solenoid valve 53, layered curing can be achieved, adjusting the curing water temperature and spraying time of each layer to realize automated curing operations. This solves the quality problems such as concrete structure cracks, reduced structural strength, and decreased durability caused by inadequate curing, thereby ensuring the structural quality of the concrete wall.

[0028] like Figure 3As shown, multiple clamps 6 are spaced apart on the sprinkler pipe 5, and the clamps 6 are connected to the tie bolts on the wall.

[0029] Since aluminum alloy formwork is required when pouring concrete walls, and tie bolts are needed for fixing during the construction of aluminum alloy formwork, the clamps 6 and sprinkler pipes 5 can be directly fixed to the tie bolts without removing them during curing. This achieves the fixing of sprinkler pipes 5 without drilling holes in the wall, thus enabling the fixing and curing of sprinkler pipes 5 without damaging the wall.

[0030] like Figure 4 As shown, a protective cover 7 is installed between two adjacent spray pipes 5. Multiple locking rings 71 are installed at both the upper and lower ends of the protective cover 7, and the locking rings 71 hook the spray pipes 5.

[0031] Therefore, by installing a protective cover 7 between the spray pipes 5 that can be quickly installed and removed, the water mist can be kept between the protective cover 7 and the wall surface during the curing process, preventing the external wind from blowing away the mist and ensuring the stable curing of the wall.

[0032] like Figure 3 As shown, the water supply pipe 4 includes multiple pipe sections 41 and a tee connector 42. The pipe sections 41 are connected to two of the ports of the tee connector 42 by clamps, and the solenoid valve 53 is connected to the other port of the tee connector 42 by clamps.

[0033] like Figure 3 As shown, the spray pipe 5 includes multiple connecting pipes 54 and a tee head 55. The connecting pipes 54 are threaded to two of the ports of the tee head 55, and the spray head 52 is threaded to the other port of the tee head 55.

[0034] Therefore, by setting up water supply pipes 4 and spray pipes 5 that can be modularly assembled, the spacing between spray pipes 5 and the spacing between nozzles 52 can be freely adjusted, which can adapt to concrete structures of various sizes and heights, especially suitable for vertical large-volume concrete, making the curing time and method more scientific and energy-saving.

[0035] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
