In order to meet the needs of multi-functional, multi-purpose and thick slabs in industrial and civil buildings, new hollow floor technology has been continuously developed and improved. Among them, hollow floor slabs with built-in spheres are particularly outstanding due to their advantages of high strength, material reduction, energy saving, sound insulation, etc., but in There is no standard guidance in application, which brings inconvenience to design, sphere manufacturing, engineering construction, and quality acceptance. Therefore, there is an urgent need to prepare corresponding engineering technical regulations. In response to the construction market's demand for built-in sphere hollow floor technology, the preparation team conducted extensive and in-depth research and organized relevant units to jointly prepare this technical regulation.
