摘要
Abstract
With the rapid development of China's transportation network,prestressed concrete has been widely used in bridges.In the process of prestressed concrete construction,the construction of steel strands is particularly important and will directly affect the quality of prestressed concrete.The elongation and retraction values of steel strands in prestressed construction are important control indicators.How to quickly and accurately measure these two parameters has become a key task in prestressed construction.The paper elaborates on the development and application of a device for measuring the elongation and retraction values of prestressed steel strands,ensuring the construction quality of precast beam concrete and improving construction efficiency.关键词
