Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of prefabricated building construction, in particular to a winter grouting constant-temperature numerical control steam curing equipment and construction method. BACKGROUND

[0002] Prefabricated buildings have become an important development direction of the modern building industry due to their high construction efficiency, short construction period, and small environmental impact. In prefabricated building construction, the connection quality between the wallboard and the floor directly affects the structural stability and durability of the entire building. The quality of this connection not only depends on the performance of the grouting material itself, but also is greatly influenced by the curing conditions.

[0003] Currently, insulation and heating methods are commonly used, such as covering insulation materials and using electric heating equipment. Although these methods can improve the temperature of the curing area to some extent, they do not control the humidity of the curing environment precisely, making it difficult to achieve the optimal temperature and humidity conditions required for grouting material curing.

[0004] However, steam curing, as an advanced curing method, has been proven in experimental conditions to provide an ideal temperature and humidity environment for grouting materials. This curing method promotes uniform solidification of grouting materials and accelerates their hardening process by providing uniform heat and moisture, thereby significantly improving the early strength and durability of the materials. However, despite the many advantages of steam curing in experimental environments, it is difficult to implement in actual construction environments, limiting its application in large-scale construction.
