冷拔低碳钢丝预应力混凝土技术是我国广大科技人员根据我国国情,从五十年代中期开始研制和发展起来的一项预应力混凝土新技术。由于这项技术符合我国国情,经济效益显著,打开了发展预应力混凝土的新局面,因此受到了重视和欢迎,在试验研究和工程实践的基础上,技术得到了不断地完善,使用范围和地区逐步扩大。目前冷拔丝预应力混凝土构件已在全国近二十个省(市、自治区)推广应用,其中以四川、江苏、浙江三省的使用范围最大,产量最高,经济效益最
Cold drawn low carbon steel prestressed concrete technology is a prestressed concrete new technology developed and developed by the majority of scientific and technological personnel in China in the mid-fifties according to China’s national conditions. As this technology is in line with China’s national conditions and the economic benefits are significant, it opens up a new situation for the development of prestressed concrete. Therefore, it has received attention and welcome. Based on experimental research and engineering practice, the technology has been continuously improved, the scope and area of use Gradually expand. At present, cold-drawing prestressed concrete components have been promoted and applied in nearly 20 provinces (municipalities and autonomous regions) in the country, among which the Sichuan, Jiangsu, and Zhejiang provinces have the largest range of use, the highest output, and the most economic benefits.
