Abstract
PURPOSE: To easily fasten a foundation bolt with a great pull resistant strength by screwing it into a concrete foundation with a spiral thread provided on the outer surface thereof.
CONSTITUTION: A ground hole 8 of a less diameter than a foundation bolt 1 is drilled at a specified position on a concrete foundation beforehand. The foundation bolt 1 is screwed down into the ground hole 8 from the tip thereof. As the foundation bolt 1 is screwing, the corner section 2a of a thread 2 cuts into the inner surface of the hole 8 to form a female-threadlike inserting hole 9. A screw section 6 is left projected from the concrete foundation A and then, inserted into a through hole 11 provided on a base 10 of a machine or a construction. Then, a seat plate 12 and a nut 13 are mounted to fix the machine or the like. This eliminates means of drilling an inserting hole of a large-diameter while the thread on the outer surface of the foundation bolt bites into the concrete thereby enhancing the pull resistant strength.
