Abstract

A post sleeve includes a reinforced concrete body preformed around a liner that defines a cavity extending longitudinally within the body, sized to receive a post. Standoff ribs run lengthwise within the cavity and extend inward from inner walls of the cavity. A post in the cavity is supported laterally by the standoff ribs. Drain channels between the ribs permit water to flow past the post and exit the cavity via a lower aperture. A drain tube is coupled to the lower aperture, and extends downward where it is covered with gravel at the bottom of a post hole. Concrete is poured around the post sleeve in the hole. The cavity is adaptable to receive posts of varying sizes, and at various depths. A collar closes a space between the post and the top of the cavity, permitting air circulation within the cavity while shedding water and substantially preventing insects from entering the cavity.

Claims

1. A post sleeve assembly, comprising:

a body having a central longitudinal axis, a first end portion at a first end of the body along the longitudinal axis, a second end portion at a second end of the body opposite the first end along the longitudinal axis, a first aperture at the first end portion, and a second aperture at the second end portion;

a cavity extending through the body along the longitudinal axis from the first aperture to the second aperture such that the cavity is exposed to an external environment of the body through the first aperture and through the second aperture, the cavity bounded by an interior wall of the body, the interior wall including a plurality of standoff elements, each standoff element having a respective innermost surface; and

a plurality of stops, each of the stops adjacent to a respective one of the standoff elements, each of the stops extending from the interior wall toward the longitudinal axis without extending toward the longitudinal axis beyond the innermost surface of the respective adjacent standoff element, each of the stops having a bearing surface that is substantially perpendicular to the longitudinal axis.

2. The post sleeve assembly of claim 1, further comprising a drain tube having a first end coupled to the second aperture such that fluid exiting the cavity through the second aperture passes into the drain tube.

3. The post sleeve assembly of claim 1, further comprising a socket positioned within the cavity and configured to receive an end of a post.

4. The post sleeve assembly of claim 3 wherein the socket is one of a plurality of sockets positioned in the cavity near the second end portion, the plurality of sockets are arranged concentrically with respect to the longitudinal axis, and each of the sockets has either a different size or a different shape than the other sockets.

5. The post sleeve assembly of claim 4, further comprising a gutter extending across each of the sockets, the gutter permitting fluid to flow out of the cavity through the second aperture when a post is positioned in one of the sockets.

6. The post sleeve assembly of claim 1 wherein at least one of the first and second apertures is threaded.

7. The post sleeve assembly of claim 1 wherein an inner space collectively defined by the innermost surfaces of the plurality of standoff elements has lateral dimensions corresponding to those of an end portion of a 4×

4 post.

8. The post sleeve assembly of claim 1 wherein each of the standoff elements includes a standoff rib extending parallel to the longitudinal axis.

9. The post sleeve assembly of claim 8 wherein each of the stops extends between a respective pair of the standoff ribs.

10. The post sleeve assembly of claim 1, further comprising a plate having a plurality of tabs, each tab configured to bear against the bearing surface of a respective stop when the plate is positioned in the cavity.

11. The post sleeve assembly of claim 10 wherein the plate includes a plate aperture configured to provide lateral support to a post extending through the plate aperture and through the cavity along the longitudinal axis.

12. The post sleeve assembly of claim 10 wherein the plate includes a socket configured to receive an end of a post extending through the cavity along the longitudinal axis.

13. The post sleeve assembly of claim 1 wherein the plurality of stops is a first plurality of stops and the post sleeve assembly further comprises a second plurality of stops, each of the second plurality of stops extending from the interior wall toward the longitudinal axis without extending toward the longitudinal axis beyond an innermost surface of an adjacent one of the standoff elements, each of the second plurality of stops having a bearing surface that is substantially perpendicular to the longitudinal axis and offset along the longitudinal axis with respect to the first plurality of stops.

14. The post sleeve assembly of claim 13, further comprising a plate having a plurality of tabs, each tab configured to bear against the bearing surface of a respective one of the second plurality of stops when the plate is positioned in the cavity.

15. The post sleeve assembly of claim 13 wherein the second plurality of stops are offset along the longitudinal axis with respect to the first plurality of stops by four inches.

16. The post sleeve assembly of claim 1, further comprising a rim extending around the first aperture and laterally outward from the first end portion of the body.
