冷轧扭钢筋是我国为节约钢材由有关单位在七十年代末自行研制成功的一种适合我国国情的新品种钢筋。应用在工程中可节约钢材40%,节约投资25%左右。1990年该项科研成果被建设部列为“八五”期间的重点推广项目,并在全国推广,对于节约钢材,降低工程成本取得明显经济效益。1995年在全国十多个地方标准的基础上,建设部下达了编制建筑行业标准《冷轧扭钢筋》和《冷轧扭钢筋混凝土技术规程》的任务,并于1996年年底出台以上两项标准。
Cold-rolled twisted steel bar is our country to save steel by the relevant units in the late seventies developed a successful new varieties of steel for our national conditions. Application in the project can save 40% of steel, saving about 25% of investment. In 1990, the scientific research achievements were listed by the Ministry of Construction as key promotion projects during the “85” period and were popularized in the whole country, which made obvious economic benefits for saving steel and reducing construction cost. On the basis of more than a dozen local standards in 1995, the Ministry of Construction issued the task of compiling the construction industry standard “Cold Rolled Twist Bars” and “Technical Specification for Cold Rolled Twisted Reinforced Concrete” and issued the above two standards by the end of 1996 .
