AI Technical Summary

Benefits of technology

The invention is a body element with a spherical taper that allows for some rotational adjustability of the anchor in situations where the bore and recess in the concrete structure are not perfectly aligned. This enables better installation of the anchor and ensures stability and reliability of the overall structure.

Problems solved by technology

When epoxy anchors, mechanical expansion anchors, and undercut anchors are used, they must usually be installed with special inspection, which can cause construction delays and add significant costs to the installation of these concrete anchors.
However, the exterior plated wall anchors can be unsightly, and have a negative visual impact on a building.

Embodiment Construction

[0020]Referring now to the drawings wherein the showings are for purposes of illustrating the preferred embodiments of the present invention only, and not for purposes of limiting the same, FIG. 1 is a cross-sectional view of a seal anchor 10 inserted into a concrete structural element 12, such as a wall. The concrete structural element 12 has a first side 16 and a second side 18. The threaded rod 14 extends from the first side 16, while the seal anchor 10 is inserted into the concrete structural element 12 from the second side 18. A bracket (not shown) can be attached to the first side 16 of the concrete structural element 12 with the threaded rod 14. Specifically, the threaded rod 14 may be inserted through an aperture formed in the bracket. A nut or other similar type of fastener is then threaded over the rod 14 to compress the bracket between the nut and the concrete structural element 12. The seal anchor 10 secures the threaded rod 14 to the concrete structural element 12 by pr...

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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention generally relates to post installed concrete anchors, and more specifically to an anchor that can securely fasten items to existing concrete structural elements, including walls, floors, beams, columns, and in particular, pre-cast concrete tilt-up wall panels.[0003]2. Description of the Related Art[0004]During the seismic retrofit of a tilt-up building, it is often necessary to secure the pre-cast concrete wall panels to the various roof and floor framing elements with wall anchorage systems. These wall anchorage systems typically consist of fasteners, brackets, struts, and / or threaded rods, that are secured to the roof or floor framing elements and then attached to the wall panel with a concrete anchor. Concrete anchors for such applications will typically consist of either an epoxy anchor, a mechanical expansion anchor, or undercut anchor embedded into the wall panel, or an exterior plated anchor...
