Scope

Main technical content: To meet the needs of multi-functional, multi-purpose, and thick-plate industrial and civil buildings, new hollow floor technologies are constantly developing and improving. Among them, the hollow floor with built-in spheres is particularly outstanding due to its advantages of high strength, material reduction, energy saving, and sound insulation. However, there are no standard guidelines for its application, which brings inconveniences to design, sphere manufacturing, engineering construction, and quality acceptance. Therefore, it is urgently necessary to formulate corresponding engineering technical regulations. In response to the demand for built-in hollow floor technologies in the construction market, the compilation team conducted extensive and in-depth investigations and studies, and organized relevant units to jointly formulate this technical regulation.
