后锚固连接中免清孔施工技术的研发与应用

Research and Application of Non-cleaning Technology in Post-installed Fastening

后锚固安装过程的清孔步骤是影响化学锚栓承载力的关键因素。本文对免清孔施工技术的产品组合,受力原理和抗震测试要求,对其在后锚固领域的应用做了详解。同时结合深圳国银民生大厦的幕墙安装项目,依据后锚固规范对免清孔施工技术的应用和产品承载力计算做了案例分析。

Effect of cleaning concrete hole is key step for the loading capacity of chemical anchor. This paper introduces the product portfolio, mechanic theory and seismic test requirement of non-cleaning （SAFEset） technology in post-installed application. Together with the project in Shenzhen Minsheng Financial Tower, calculation example is presented based on post-installed design code.
