屋面漏水是建筑技术上的“老大难”。长期以来,许多单位进行了研究。中国建筑科学研究院与有关单位协作,经过七年时间,研制成功的冷拌沥青珍珠岩(JG-0)、油溶型防水冷胶结料(JG-1)和水乳型防水冷胶结料(JG-2)三项保温防水新材料,基本上解决了沥青油毡防水屋面工程存在的起鼓、渗漏问题;改热作业为冷施工,操作简便,改善了劳动条件;减轻了屋盖重量,经济效果也很显著。如果在100万米2的屋面工程中,用这种新材料衬加玻璃纤维布代替两毡三油的传统作法,可节省沥青4000～5000吨,木柴4800～5400吨,降低造价50万元以上。目前,已在28个省、市应用了400多万米~2。为便于推广应用,本刊将陆续介绍有关文章。
Leaking of roofing is “premature” in construction technology. For a long time, many units have conducted research. In collaboration with related organizations, the China Academy of Building Research, after seven years of development, successfully developed cold-mixed asphalt perlite (JG-0), oil-soluble waterproof cold binder (JG-1) and water-emulsion-type waterproof cold binder ( JG-2) Three new thermal insulation and waterproof materials basically solved the problem of kicking and leakage of bitumen tared waterproof roofing projects; the heat change operation was cold construction, the operation was simple, the working conditions were improved, and the weight of the roof was reduced. The economic effect is also significant. In the case of a roof project of 1 million m2, the traditional practice of replacing glass wool with this new material in place of two felts and three oils can save 4,000 to 5,000 tons of asphalt, 4800 to 5,400 tons of firewood, and reduce the cost by more than 500,000 yuan. . At present, more than 4 million meters~2 have been applied in 28 provinces and cities. In order to facilitate the promotion and application, the journal will introduce relevant articles one after another.
