高强度螺栓是工业、民用钢结构建(构)筑物的重要组成部分。近些年来随着我国钢结构的迅猛发展,钢结构用高强度螺栓的生产厂家和产量也不断增加,从事钢结构用高强度螺栓检测的机构也越来越多。但由于一些检测方法不规范或检测设备不适合,造成检测结果的差异和离散较大,致使对产品的质量争议越来越多,给高强度螺栓生产企业和施工企业带来困扰和经济损失、给工程质量造成隐患。为了确定、规范、提高钢结构用高强度螺栓生产企业和第三方检测机构对钢结构用高强度螺栓的检测能 High-strength bolts are industrial, civil steel structures (structures) building an important part. In recent years, with the rapid development of China’s steel structure, the manufacturers and output of high strength bolts for steel structures have also been increasing. More and more institutions are engaged in testing high strength bolts for steel structures. However, due to some non-standard detection methods or testing equipment is not suitable, resulting in large differences in test results and discrete, resulting in more and more controversial product quality, high-strength bolt manufacturing enterprises and construction enterprises and economic losses caused by distress, To create a hidden danger to the quality of the project. In order to determine, standardize and improve the use of high-strength steel bolts manufacturing enterprises and third-party testing agencies on the detection of high strength steel bolts
