Description

Technical Field

[0001] The utility model relates to the technical field of spray devices, in particular to an automatic spray device for maintaining concrete crack prevention structures of high-rise residential buildings. Background Art

[0002] Concrete curing is to artificially create certain humidity and temperature conditions so that the newly poured concrete can harden and increase its strength normally or accelerate its hardening. 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. If the surrounding environment does not have such conditions, the concrete needs to be cured manually. Concrete curing is divided into natural curing and heating curing according to different construction processes. Natural curing refers to keeping the concrete moist for a period of time under natural conditions. It has the advantages of simple construction and low energy consumption, but the curing takes a long time and is suitable for the curing of various concrete structures. The methods are divided into watering curing, film drip irrigation curing, plastic film covering curing, film curing liquid curing, etc.; heating curing refers to curing the concrete precast parts under high temperature and high humidity conditions. This method can accelerate the strength growth of the concrete precast parts, achieve their design performance in a short time, and speed up the mold turnover, but it consumes a lot of energy, has a complex structure, and is costly. The methods include steam curing, hot mold curing, and solar heating curing. The maintenance of concrete crack prevention structures in high-rise residential buildings generally uses spraying devices for water curing.
