来自北京、上海、天津、山西等省市的七十四名专家和工程技术入员对自贡市建筑工程设计院等单位设计、研制的大跨、重载、高强页岩陶粒混凝土预应力空心楼板进行了鉴定。经过对技术文件的评审和实地考蔡,全体代表一致认为,这项设计和研制是成功的,在应用技术上有新的发展和突破,尤其框架、墙体、预应力楼板全部采用轻混凝土,这在国内还是第一个工程。代表们一致建议推广使用。 Seventy-four experts and engineering technicians from Beijing, Shanghai, Tianjin, and Shanxi Province designed and developed a large-span, heavy-duty, and high-strength shale ceramsite concrete pre-stressed hollow designed and designed by the Zigong City Architectural Engineering Design Institute and other units. The floor was identified. After reviewing the technical documents and field tests, all representatives agreed that the design and development were successful, and there were new developments and breakthroughs in applied technology. In particular, the framework, walls, and prestressed floors were all made of light concrete. This is the first project in the country. Delegates unanimously recommended the promotion of use.
