    • A method and system for securing an anchor in a hard substance or rigid material (34) include a cutter bit (24) for drilling a hole in the hard substance, an anchor for fitting within the drilled hole, the process of drilling the hole using the cutter bit, the drilling machine (10) for using the cutter bit, and the resulting improved hard substance or rigid material that may be used as a curtain wall for fastening to a building or similar structure. The hard substance may be a sheet of granite, marble, glass, limestone, or other similar material. The invention includes an anchor that has a cylindrical shaft, a bevelled head portion, and an expanding collar for fitting within and securing the anchor in a drilled hole of the hard substance. The drilled hole includes a bevelled bottom portion that receives the bevelled head portion of the anchor and the expanding collar. A placement device transmits an impacting force to place the expanding collar around the bevelled head portion of the anchor. This secures the anchor in the drilled hole in a time-saving and highly reliable manner.
    • 用于将锚固件固定在硬质材料或刚性材料中的方法和系统包括用于在硬质材料中钻孔的切割钻头,用于装配在钻孔内的锚固件,使用切割钻头钻孔的过程,钻孔 用于使用切割刀头的机器,以及所得到的改进的硬物质或刚性材料,其可以用作用于紧固到建筑物或类似结构的幕墙。 硬质物质可以是花岗岩,大理石,玻璃,石灰石或其他类似材料。 本发明包括具有圆柱形轴,倾斜头部和膨胀套圈的锚固件,用于安装在固定件内并将其固定在硬质物质的钻孔中。 钻孔包括倾斜的底部,其接收锚固件的倾斜头部和膨胀套环。 放置装置传递冲击力以将扩张的环绕在锚的倾斜头部周围。 这样可以节省时间和高度可靠的方式将锚固在钻孔中。
