Scope

This document specifies the basic requirements for intelligent steam curing of precast concrete components, the layout and construction of steam curing sheds, intelligent control systems, steam delivery and regulation, data storage, quality control, safety, and environmental protection. This document applies to all types of intelligent steam curing of precast concrete components. Main technical content: The "Technical Regulations for Intelligent Steam Curing of Precast Concrete Components" (T/JSJTQX 79—2025) specifies the basic requirements for intelligent steam curing of precast concrete components, the layout and construction of steam curing sheds, intelligent control systems, steam delivery and regulation, data storage, quality control, safety, and environmental protection. It applies to all types of intelligent steam curing of precast concrete components. The main content is as follows: I. Basic requirements Following the principles of systematization, standardization, safety, and environmental protection, a special plan and safety technical briefing are required before construction. The curing parameters are determined according to the type and size of the components and the type of cement. The intelligent system needs to monitor the environment in real time, and the layout of the steam curing sheds should be connected to the production process. II. Intelligent steam curing facilities (I) Steam curing sheds The priority is to use "steel structure + rock wool board/polyurethane foam board". The steel structure can resist temperature changes and wind and snow, and the insulation materials are tightly spliced. The size should match the production needs: leaving 1~1.5m of operation space at both ends of the components, and the shed roof should be 1~1.5m higher than the components; the lighting should have a waterproof rating of ≥IP65, and the ventilation vents should be evenly distributed. (II) Steam pipelines and equipment The pipelines should b
