Description

Technical Field

[0001] The invention relates to the technical field of concrete curing, and in particular to a spray curing device for a house concrete structure. 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 required during house construction. Conventional curing operations are performed by people dragging water pipes for spraying curing. The coverage of the nozzle is limited and it needs to be swung back and forth manually, which is very labor-intensive.

[0003] Those skilled in the art have conducted research and improvements on this, such as a concrete spray curing device for house construction with application number CN202323629146.6. This technical solution uses a hydraulic cylinder to adjust the height of the bracket, thereby adjusting the height of the spray mechanism inside the bracket, and can make corresponding height supplements to achieve auxiliary spraying. This device can achieve good spray curing effects on vertical surfaces, but when spraying and curing concrete structures on horizontal surfaces, the water outlet position is not easy to adjust, and spray dead angles are prone to occur.
