Abstract
An adhesive insert includes a first end and a second end, and comprises a threaded portion at the first end, the threaded portion having a circular cross-section. A securing portion is provided at the second end, the securing portion including an anti-rotation structure formed therein which resists rotation of the insert under cyclic loading by the building element. The anti-rotation structure may be a triobular cross-section formed in the securing portion. Other anti-rotation structures are provided.
Claims20
An adhesive insert suitable for securing a building element to concrete, the anchor having a first end and a second end and including:
- a threaded portion at the first end, the threaded portion having a circular cross-section;
- and
- a securing portion at the second end, the securing portion including a plurality helical threads having a constant pitch forming an anti-rotation structure, each thread formed by a continuous upper helical surface and a corresponding continuous helical lower surface separated from adjacent threads by a spacer and having a tri-obular cross-section, the anti-rotation structure resisting rotation of the anchor under cyclic loading by the building element.
An adhesive insert suitable for securing an element to a concrete foundation, the insert including:
- a threaded portion having a circular cross-section capable of receiving a threaded nut;
- and
- a securing portion comprising a plurality of helical threads each having a constant pitch and a triobular cross section, each thread formed by an upper continuous helical surface and a lower continuous helical surface separated from adjacent threads by a spacer.
An system for securing an adhesive insert suitable for use in a pre-drilled hole, comprising;
- a threaded portion at a first end for the adhesive insert, the threaded portion having a circular cross-section;
- an insert section including one or more continuous helical threads having a constant pitch, each of said helical threads having a triobular cross-section and formed by a continuous upper surface and a continuous lower surface;
- and
- an adhesive surrounding the insert section in the pre-drilled hole and in contact with the hole and the insert section.
A system for anchoring a foundation, comprising:
- an axially extending rod having leading end inserted into the pre-drilled bore and a trailing end, the trailing end including a threaded portion having a circular cross-section, the leading end having a securing region with a helical profile extending from the leading end towards the trailing end on an outer surface, wherein the profile includes an anti-rotation structure formed in the profile which inhibits rotation of the insert under cyclic loads applied to the rod, the anti-rotation structure comprising a plurality helical threads having a constant pitch, each thread formed by an upper continuous helical surface angled with respect to a lower continuous helical surface, each thread separated from adjacent threads by a spacer and having a triobular cross-section;
- and
- an adhesive surrounding the anti-rotation section and in contact with the hole and the insert section.
