Description

Technical Field

[0001] The present invention relates to the technical field of building maintenance, and in particular to a circulating spraying assembled building structure maintenance device. Background Art

[0002] Prefabricated construction refers to a construction method in which some or all of a building's components are manufactured in a prefabrication factory, transported to the construction site, and assembled using safe and reliable installation methods and machinery to create a functional building. Mixed concrete is poured into molds to create a variety of prefabricated building structures. This method not only improves factory-based and mechanized construction, reduces on-site wet work, but also saves on-site labor, overcomes seasonal effects, and shortens the construction cycle.

[0003] The hardening and strength of concrete requires a certain temperature and humidity. Concrete is an artificial stone formed by mixing cement, aggregate, and water and then hardening. Cement is a hydraulic binder. During the setting process, water evaporates from the concrete. This lack of water severely impacts hydration, causing the concrete to set slowly. Especially in dry and windy weather, water in the concrete's pores evaporates rapidly. Not only does the lack of water cause cement hydration to cease, but capillary attraction also causes shrinkage within the concrete. The resulting tensile force quickly causes cracking. Furthermore, the concrete's strength is still very low at this stage. External vibrations can further damage the concrete structure, easily leading to quality issues.

[0004] At present, the direct spraying method is a method of spraying water directly on concrete building structures. Since there is no covering to prevent the rapid evaporation of water, a considerable amount of water is required to keep the concrete surface moist. In addition, due to the rapid evaporation of water, manual spraying is required continuously. Therefore, the direct spraying method not only consumes a large amount of water resources, but also wastes human resources, which is contrary to the concept of energy conservation and environmental protection.
