Scope

Large-scale public buildings such as convention and exhibition centers, transportation hubs, hospitals, theaters, stadiums, data centers, and large-scale commercial complexes generally have the characteristics of large structural volume, high functional load, large spatial span, thick foundations and core cylinders, deep underground spaces, and long continuous pouring sections. During construction, thick floor slabs, thick roof slabs, thick shear walls, piers, and large-section conversion components are widely used. Such components have concentrated concrete hydration heat, long heat dissipation paths, significant constraints on temperature gradients and volume deformation, and are prone to temperature cracks and shrinkage cracks, which in turn lead to problems such as leakage, deterioration of durability, damage to structural stiffness and functional use, and significant increases in subsequent maintenance costs. Current national standards have set forth temperature control indicators and temperature monitoring and control requirements for large-scale concrete construction, such as giving limit principles for key control indicators such as temperature rise and internal-external temperature difference, and requiring the formulation of corresponding temperature control technical measures; at the same time, they provide operable provisions for the layout of monitoring points and monitoring. However, in the context of public buildings, temperature control measures and crack prevention often need to be implemented and evaluated in a closed loop based on practical conditions such as complex work organization, dense pre-embedded electrical and mechanical installations, multiple interfaces of waterproofing systems in decoration, compressed construction periods, and cross-disciplinary operations of multiple professions. This document takes "plan-first, data-driven, full-process control, and closed-loop evaluation" as the main line, and proposes requirements for constructi
