Technical Field

[0001] This utility model belongs to the technical field of concrete construction and curing equipment, specifically relating to a spraying device for concrete floor construction. Background Technology

[0002] After the concrete floor is poured, timely spray curing is a crucial step in ensuring the quality of the project. Spray curing mainly involves evenly spraying water mist onto the surface of the newly poured concrete to maintain suitable humidity and temperature, promoting full hydration of the cement. This effectively prevents problems such as surface powdering, spalling, or shrinkage cracks caused by dehydration of the concrete. It plays an irreplaceable role in improving the final strength, durability, and overall quality of the concrete.

The rotating rod 142 is rotatably mounted inside the middle cylinder 141, and its two ends extend from the... The middle cylinder 141 extends out at both ends, and the spraying mechanism 2 is installed at both ends of the rotating rod 142. The middle cylinder 141 is fixedly connected to the support rod 11. The spraying mechanism 2 includes a connecting pipe 21 and a nozzle 22. One end of the connecting pipe 21 is connected to a water supply pipe, and the other end is connected to the nozzle 22.
