Description

Technical Field

[0001] This invention relates to the field of concrete curing technology, and more specifically to a concrete curing device for building construction. Background Technology

[0002] In construction engineering, concrete curing is a common construction process. Curing provides suitable temperature and conditions for concrete, allowing it to undergo a continuous and thorough hydration reaction, thereby gradually hardening and gaining strength. This is crucial for concrete to achieve its designed strength and performance. At the same time, curing also plays a role in preventing cracking caused by premature drying of concrete after pouring, controlling changes in concrete temperature, improving the impermeability and durability of concrete, and enhancing the overall performance of concrete.

[0003] Traditional concrete curing devices commonly suffer from uneven insulation and humidification effects, poor sealing between curing units, low efficiency due to reliance on manual experience for control, and inability to stably guarantee the early strength development of concrete during winter construction. Specifically, traditional methods such as straw mats and plastic sheets are not airtight, resulting in rapid heat and humidity loss, and the reliance on manual timed monitoring and adjustment leads to delayed response and an inability to achieve precise constant temperature and humidity curing, thus affecting concrete quality and construction efficiency. Therefore, a concrete curing device for building construction is proposed. Summary of the Invention

[0023] IV. This application features a reasonable structure and enhanced integrated functions: the expansion bag can be weighted up by adding water to ensure that the insulation blanket is tightly attached to the concrete surface, thus enhancing the sealing performance. The filter screen and filter cotton in the water storage mechanism filter the curing water to prevent scale from clogging the pipes. In summary, this device, through its three-in-one design of "rapid sealing combination, uniform steam distribution, and intelligent feedback control," successfully solves the core pain points of traditional curing methods, such as poor sealing performance, uneven effects, and rough control, providing high-quality and efficient curing guarantee for winter concrete construction.

[0067] Start the steam generator 18: The electric butterfly valve opens, water flows through the transfer pipe 27 into the generator, and saturated steam is generated and transported through the delivery pipe 21.

[0068] Steam distribution: Steam is evenly distributed through steam pipeline 12 and evenly released through exhaust holes 22 in the diversion pipe 13;

[0069] The insulation system works in tandem: the insulation layer 11 reflects heat energy, and the insulation layer 10 reduces heat loss;

[0070] 14 Wireless Temperature and Humidity Sensors for Real-Time Monitoring: Concrete Surface Temperature and Ambient Humidity;

[0071] Control unit 4 intelligent regulation: Adjusts the opening of solenoid valve 23 according to monitoring data to control the steam output temperature at 55±5℃ and maintain relative humidity ≥90%;

[0072] Regular checks: 1. Ensure the insulation blanket is sealed properly; 2. Ensure the steam pipe network 12 is reliably connected; 3. Ensure the sensor data is accurate.

[0073] Adjust as needed: Adjust steam output according to temperature changes, replenish water in water tank 19, and clean filter screen 25 and filter cotton 26;

[0074] After maintenance is completed, shut off the following in sequence: power supply to steam generator 18, power supply to water pump 20, and solenoid valve 23.

[0075] System disassembly: Disconnect steam pipe network 12 joints 5, disassemble the combined component connections, and drain the water accumulated in the extension bag 2;

[0076] Equipment storage: Clean the surface of each component, check the equipment for integrity, and store it properly for future use.
