Abstract
An anchor for securing a threaded rod to a concrete structural element has a generally tapered conical or spherical body element configured to be seated within the concrete structural element. The anchor further includes a threaded bore extending through the body element. The threaded bore engages the threads of the rod in order to secure the rod to the concrete structural element. The body element has a generally planar top face having a top face diameter, as well as a generally planar bottom face having a bottom face diameter. Formed between the top face and the bottom face is a side wall such that the body element is formed with a taper. The taper is inserted into a complementary recess formed within the concrete structural element.
Claims14
An anchor for securing a threaded rod to a concrete structural element, the anchor comprising:
- a generally conical or partially spherical body element configured to be seated within the concrete structural element;
- and
- a threaded bore extending through the body element;
- wherein the threaded bore engages the rod in order to secure the rod to the concrete structural element.
A method of securing a threaded rod to a concrete structural element with a generally conically or spherically shaped anchor having threads, the method comprising the following steps:
- forming a bore sized slightly larger than the threaded rod within the concrete structural element;
- forming a recess complementary to the shape of the anchor within the concrete structural element, the recess being axially aligned with the bore;
- inserting the threaded rod into the anchor so as to engage the threads of the anchor;
- and
- inserting the combined threaded rod and anchor into the bore and recess such that the anchor secures the threaded rod to the concrete structural element.
A method of forming an anchor to attach a threaded rod to a concrete structural element from a body element, the method comprising the steps of:
- forming a generally planar top face having a top face diameter on the body element;
- forming a generally planar bottom face having a bottom face diameter on the body element;
- forming a side wall between the top face of the body element and the bottom face of the bottom element such that the side wall tapers from the top face to the bottom face;
- and
- forming a threaded bore within the body element between the top face and the bottom face, the threaded bore being configured to engage the threaded rod.
The method of claim 132 further comprising the step of upsetting the threads of the bore adjacent to the top face in order to prevent the threaded bore from running through the body element.
