简介:摘 要: 近年来,社会经济发展速度明显加快,在工程建设各领域中,国家逐渐加大了基础设施的投入力度,一定程度上推动了建设工程各类施工技术的应用。其中,钢筋连接技术的创新与发展即充分体现了工程项目施工技术的价值。基于此,文章将钢筋连接技术作为主要研究对象,在阐述技术发展现状的同时,以镦粗直螺纹套筒连接技术为例,重点研究此技术的控制要点,希望有所帮助。
简介:摘要:为解决传统弯钩锚固存在的问题,本文提出采用钢筋镦锚技术作为钢筋的机械锚固方式。通过一系列拉拔试验,对比了镦锚钢筋、带锚固板钢筋、以及带900标准弯钩钢筋在混凝土块体中的机械锚固性能,并分析了钢筋位置、保护层厚度对锚固强度的影响。并通过低周往复试验,验证了镦头锚固在地震作用时的可靠性。试验结果表明采用钢筋镦锚技术具有和钢筋锚固板以及传统弯钩锚固相当的锚固强度,采用钢筋镦锚技术可以取代传统弯钩锚固形式。
