Abstract
A construction anchor for mounting an object on a structure of masonry, concrete, metal or the like includes a metal anchoring portion and a plastic cap. The anchor is adapted to be inserted, metal end first, into a pre-drilled adhesive-filled hole. The cap has a flange that is larger than the hole diameter, so that the anchor may be inserted and seated in the hole at a consistent depth. When the adhesive has set, a screw or bolt is inserted through the plastic cap to engage the threads in an internal bore in the anchoring portion. The plastic cap serves not only to determine the depth of the anchor in the hole, but also to prevent adhesive and other material from entering the threaded interior of the anchor prior to use.
Claims28
A construction anchor for retaining an object against..,.!. a structure of masonry, concrete, metal or the like, said construction anchor, in use, being secured within a hole defined in said structure, comprising:
- a cylindrical anchoring portion having a threaded axial bore extending partially through said anchoring portion from one end thereof;
- and
- a cap adapted to be snap-fit over said end to cover said threaded axial bore, said cap having an annular flange seatable on the periphery of said hole, so that said construction anchor may be set into said hole at a predetermined and consistent depth.
A construction anchor for retaining an object against a structure of masonry, concrete, metal or the like, said construction anchor, in use, being secured within a hole defined in said structure, said construction anchor comprising a cylindrical member having a first end, a second end and a longitudinal axis, a threaded axial bore extending partially therethrough from said first end, and at least one first annular groove around said second end, thereby providing a lobe in said cylindrical member at said second end, said lobe having a surface oriented obliquely with respect to said longitudinal axis, said threaded axial bore terminating within said cylindrical member short of said at least one first annular groove and a cap tightly fitted upon said first end to cover said threaded axial bore.
