摘要:对冷作强化直螺纹套筒力学性能进行试验研究,研究结果表明,冷作强化直螺纹套筒高温后力学性能降低,不满足相关规范要求;作为对比,45号钢直螺纹套筒高温后力学性能无明显变化,满足相关规范要求。应用冷作强化直螺纹套筒时,在有耐火要求的情况下,需开展套筒入场防火性能检验。

Abstract: The mechanical property of the cold hardening parallel threaded sleeves was studied. The experimental results show that the mechanical property of the cold hardening parallel threaded sleeves after high temperature heating reduced,can not meet the standards. As a comparison,there is no obvious change for the mechanical property of the 45 parallel threaded sleeve after high temperature heating.When the cold hardening parallel threaded sleeve is used in the condition that the sleeve has to satisfy the performance of fire resistance for construction engineering,the admission inspection of fire resistance for the sleeves must be done.
Keywords: prefabricated; parallel threaded sleeves; cold hardening; mechanical properties; fire resistance; testing
