Abstract
A spring bolt hanger comprising a barrel, a bolt positioned within the barrel, a retainer associated with the bolt, and a spring positioned in the barrel between the retainer and a first end of the barrel, said spring configured to bias the bolt away from the first end of the barrel. The spring bolt hanger has two distinct operative configurations. In the retracted configuration the spring bolt hanger has the bolt retracted into the barrel. In the extended configuration the bolt is extended from the barrel and is accessible outside of the concrete surface for use as an attachment point. The spring bolt hanger may be selectively moved between operative configurations. Also disclosed are methods of using a spring bolt hanger to attach an object to a concrete surface.
Claims18
A spring bolt hanger comprising:
- a barrel comprising a rod barrel section and a spring barrel section, wherein the rod barrel section has a diameter smaller than a diameter of the spring barrel section, wherein the rod barrel section is permanently fixed with respect to the spring barrel section and wherein the spring barrel section is permanently fixed with respect to the rod barrel section;
- a bolt positioned within the barrel;
- a retainer associated with the bolt;
- and
- a spring positioned in the barrel between the retainer and a first end of the barrel, said spring configured to bias the bolt away from the first end of the barrel, wherein the retainer, the plurality of first internal stops, and the spring are positioned in the spring barrel section.
A method of attaching an object to a concrete surface comprising:
- providing a spring bolt hanger comprising:
- a barrel comprising a rod barrel section and a spring barrel section, wherein the rod barrel section has a diameter smaller than a diameter of the spring barrel section, wherein the rod barrel section is permanently fixed with respect to the spring barrel section and wherein the spring barrel section is permanently fixed with respect to the rod barrel section;
- a bolt positioned within the barrel;
- a retainer associated with the bolt;
- and
- a spring positioned in the barrel between the retainer and a first end of the barrel, said spring configured to bias the bolt away from the first end of the barrel such that an end of the bolt may extend beyond an opposite end of the barrel wherein the retainer, the plurality of first internal stops, and the spring are positioned in the spring barrel section;
- embedding the spring bolt hanger in concrete;
- extending the bolt to an extended state where the end of the bolt extends beyond the barrel;
- and
- attaching the object to the extended end of the bolt.
