在工厂中安装机床,通常都是使用地脚螺钉浇灌混凝土的传统方法。近年来,我厂采用膨胀螺栓安装机床(如图1)效果很好。　　　　用膨胀螺栓和胀管(图2),不需在基础中予留方孔,只要在已浇注混凝土的地面上钻孔就可进行安装机床了,而且当天安装当天就可校水平并投入生产试车。膨胀螺 Installing a machine tool in a factory is usually a traditional method of pouring concrete using anchor bolts. In recent years, I plant expansion bolts installed machine (Figure 1) works well. With expansion bolts and expansions (Figure 2), there is no need to leave a square hole in the foundation, as long as the ground has been poured concrete drilling can be installed on the machine, and the day of installation can be level and put into production test .
