为了解决石膏珍珠岩空心隔墙板存在的脆性问题,门口板的抗冲击性问题及施工运输包装等方面存在的问题,原北京市水泥砖瓦厂和北京市建筑设计院研究所、北京市第六建筑工程公司合作,于1980年开始研制增强石膏条板。增强石膏条板以半水石膏和少量水泥作胶结材料,膨胀珍珠岩为轻骨料,板的两面内埋涂塑玻璃纤维网。它既具备了原石膏空心条板的轻质高强、隔热防火、造价低廉、安装方便等优点,又改善了脆性、满足了门口板抗冲击的要求。该产品已生产了5万平方米在北京儿童医院塔
In order to solve the brittleness problem of hollow perforated gypsum perspex panels, problems with the impact resistance of doorway panels and problems in construction and transportation packaging, the former Beijing Cement and Brickyards and Beijing Institute of Architectural Design Institute, Beijing Six construction engineering companies cooperated to develop reinforced gypsum strips in 1980. The reinforced gypsum board uses hemihydrate gypsum and a small amount of cement as the cementing material. The expanded perlite is a lightweight aggregate. The two sides of the board are coated with a glass fiber mesh. It not only possesses the advantages of lightweight, high strength, fireproof, fireproof, low cost, and easy installation of the original gypsum hollow strip, but also improves the brittleness and meets the requirements of the impact resistance of the door panel. The product has produced 50,000 square meters in Beijing Children’s Hospital Tower
