Abstract
An insert for construction supports such as joist hangars and hurricane straps provides corrosion protection from chemicals and moisture in exterior construction lumber. The insert is a semi-rigid body having a shape that fits the construction support so that surfaces of the insert are disposed between the support and the construction lumber at joints in the construction. In the preferred embodiments, the inserts are made of a plastic material and provide a chemical, moisture and electrical barrier between the support and exterior lumber elements of a structure.
Claims23
A corrosion protection insert for metallic construction supports used in attaching a treated lumber, said insert comprising:
- a semi-rigid body of a polymeric material, said body comprising a predefined shape wherein at least two orthogonal insert attachment surfaces of said insert fit between corresponding support attachment surfaces of said construction support and corresponding treated lumber attachment surfaces.
The corrosion protection insert of claim 7 wherein said male fastener element is a button tab and said complementary element is a nail hole on said construction support.
A corrosion protection construction support for use with treated lumber, said support comprising:
- a metallic body comprising at least two orthogonal attachment surfaces for attaching said treated lumber;
- and
- a polymeric film attached to said metallic body whereby said film separates said metallic body and said treated lumber thereby preventing corrosion of said metallic body.
A method of reducing corrosion of metallic construction supports used with treated lumber, the method comprising the step of placing a semi-rigid, preformed polymeric insert having at least two orthogonal surfaces between joining surfaces of said treated lumber and said metallic construction support.
