Abstract

A support member for supporting a guardrail with respect to a support post is provided. The support member comprises a body including a first portion adapted to engage a mounting area of a support post and a second portion adapted to engage a mounting area of a guardrail. The first portion comprises a mounting surface that is substantially concave from a first side to a second side of the mounting surface. The first side is provided with a first mounting protrusion and the second side is provided with a second mounting protrusion. Guardrail assemblies including a support member and methods are further provided.

Claims

1. A method of providing a guardrail assembly comprising the steps of:

providing a support post including an outer surface with a convex mounting area and an aperture extending through the convex mounting area;

providing a guardrail including a mounting area and an aperture extending through the mounting area;

providing a support member comprising a mounting surface that is concave from a first side to a second side of the mounting surface, wherein the first side is provided with a first mounting protrusion shaped as a vertically elongated rib integral with the mounting surface and the second side is provided with a second mounting protrusion shaped as a vertically elongated rib integral with the mounting surface, wherein an aperture extends through the concave mounting surface;

providing a fastener device including a first end portion, a second end portion, and an intermediate portion;

positioning the support member with respect to the support post such that the first and second mounting protrusions engage the support post and straddle the convex mounting area of the support post;

positioning the intermediate portion of the fastener device through the aperture of the support post, the aperture of the support member and the aperture of the guardrail; and

tightening the fastener device wherein at least a portion of the concave mounting surface of the support member engages at least a portion of the convex mounting area of the support post and the first and second protrusions are at least partially embedded within the support post.

2. The method of claim 1, wherein the concave mounting surface of the support member is provided with a first radius and the convex mounting area of the support post is provided with a second radius, wherein the first radius is greater than the second radius prior to the step of tightening, and the first radius is equal to the second radius of at least a portion of the convex mounting area after the step of tightening.
