Abstract

A system includes an anchor body, having a head and a hollow chamber shaft coupled to the head. The system includes a housing component configured to support the anchor body. The system also includes one or more fasteners supported by the housing component. At least one of the fasteners is coupled to the head of the anchor body, and an apex of each fastener is positioned to be above the head of the anchor body.

First claim

What is claimed is:

1. A system, comprising:
an anchor body comprising a head and a hollow chamber shaft coupled to the head;
a housing configured to support the anchor body;
one or more ribs coupled to the anchor body and tapered in a lengthwise direction of the housing; and
one or more fasteners supported by the housing, wherein at least one fastener of the one or more fasteners is coupled to the head of the anchor body, and wherein an apex of the at least one fastener is positioned to be above the head of the anchor body.

2. The system of claim 1 , wherein the hollow chamber shaft comprises a multi-thread area comprising two or more threads of varying diameters configured to engage a construction surface.

3. The system of claim 1 , wherein a bottom surface of the apex of each of the one or more fasteners is adjacent a top surface of the head of the anchor body in a press-fit interference connection, and wherein each of the one or more fasteners is configured to pass through the head of the anchor body.

4. The system of claim 1 , wherein each of the one or more fasteners is coupled to the head of the anchor body via a friction fit, an interlock connection, a welded connection, or a threaded connection, or wherein each of the one or more fasteners is bent slightly below the head of the anchor body.

5. The system of claim 1 , further comprising a seal configured to seal a gap between the housing and the hollow chamber shaft.

6. The system of claim 5 , wherein the seal is a compressible foam gasket.

7. The system of claim 5 , wherein the seal comprises a visual indicia configured to uniquely identify the system, and wherein the visual indicia comprises a color, a text, a number, or a combination thereof.

8. The system of claim 5 , wherein the seal is configured to be removable to engage and disengage from the gap between the housing and the hollow chamber shaft.

9. The system of claim 5 , wherein the seal is a fixed construction and comprises one or more flexible fingers configured to allow a construction surface to pass therethrough.

10. The system of claim 1 , wherein the one or more tapered ribs are disposed along a length of the anchor body, and wherein the one or more ribs contact a bottom surface of the head of the anchor body when the system is installed.

11. The system of claim 1 , wherein each of the one or more fasteners comprises a nail.

12. The system of claim 1 , wherein the head of the anchor body comprises a shape selected from the group consisting of a circular shape, a hexagonal shape, a heptagonal shape, a square shape, a pentagonal shape, an octagonal shape, and any combination thereof.

13. The system of claim 2 , wherein the construction surface comprises a pipe, a sprinkler system, an HVAC surface, a conduit, a surface of an area comprising an electrical system, or any combination thereof.

14. The system of claim 1 , wherein:
the one or more fasteners comprise a plurality of fasteners, and
each of the one or more ribs are disposed along an outer surface of the housing between a respective pair of the plurality of fasteners.

15. The system of claim 1 , wherein:
each of the one or more ribs have a bottom width and a top width, and
the bottom width is greater than the top width to form the taper in the lengthwise direction of the housing.

16. The system of claim 1 , wherein the hollow chamber shaft comprises at least one tapered wall.

17. The system of claim 1 , wherein a width of each of the one or more ribs is greater than a distance between each of the one or more fasteners and the hollow chamber shaft.

18. The system of claim 2 , wherein the multi-thread area comprises at least one automatic clamping area.

19. The system of claim 18 , wherein the multi-thread area comprises a first automatic clamping area having a first size and a second automatic clamping area having a second size different from the first size.

20. The system of claim 1 , further comprising:
a non-removable barrier comprising one or more flexible appendages configured to block access into the hollow chamber shaft.
