Multi-purpose bolt unit for fixing object to drilled hole of soft construction structure
A multi-purpose bolt unit for fixing an object to a drilled hole formed in a soft construction structure. The multi-purpose bolt unit including: a cylindrical body inserted into the drilled hole; a front end tip formed at a lower end of the cylindrical body and having a larger outer diameter than an outer diameter of the cylindrical body; an upper thread surface formed in an upper side of the cylindrical body while spaced apart from the front end tip; an elastic packing pipe inserted into the cylindrical body and placed on the front end tip; an upper washer inserted into the cylindrical body and placed on the elastic packing pipe; a compression nut screwed to the upper thread surface and pressurizing the upper washer so that the elastic packing pipe expands; and a fastening screw groove formed inside the cylindrical body and opened upward through the compression nut.
