Guardrail support, attachment, and positioning block
First Claim
1. A spacer block for attaching a guardrail to a support post, comprising:
- a pair of side-walls having respective first and second ends;
a top panel disposed proximate the first end of the side-walls;
a bottom panel disposed proximate the second end of the side-walls;
the top panel, bottom panel and side panels forming a generally rectangular block having respective first and second faces;
at least one mounting bore traveling between the first and second face of the block;
an engagement mechanism slidably engaged with the top panel, the engagement mechanism operable to engage the block with the support post; and
a resting mechanism operably coupled proximate the bottom panel, the resting mechanism operable to support a guardrail during assembly.

Abstract
A guardrail support, attachment and positioning block used to space guardrails from support posts is disclosed. The positioning or spacer block is a generally rectangular block having corded-out cavities to reduce weight and tabs or projections for cooperatively engaging the sides and top of a support post as well as the edges of the guardrail during roadway safety barrier system installation. Webbing within one or more of the cavities may be used for additional structural support. To optimize the strength to weight characteristics of the spacer block, the spacer block may be formed by low-pressure injection molding. The spacer block may also be formed from virgin and/or recycled plastic material and/or include virgin or recycled rubber material, such as that obtained from the regrind of used tires, and/or another elastomeric materials from other sources.

4. The spacer block of claim 2 further comprising a reinforcement structure disposed in at least one of the cavities.
-
5. The spacer block of claim 2 further comprising a webbing structure disposed within at least one of the cavities, the webbing structure operable to structurally reinforce the spacer block.
-
6. The spacer block of claim 1 further comprising:
-
first and second medial walls disposed generally perpendicular to the side-walls and generally parallel to the top and bottom panels;
the first medial wall, side-walls and top panel creating a first cavity;
the first medial wall, second medial wall and side-walls forming a second cavity; and
the second medial wall, side-walls and bottom panel forming a third cavity.
-
-
7. The spacer block of claim 6 further comprising:
-
at least one mounting bore disposed in the first medial wall, the mounting bore traveling between the first and second faces of the spacer block; and
at least one mounting bore disposed in the second medial wall, the mounting bore traveling between the first and second faces of the spacer block.
-
-
8. The spacer block of claim 1 further comprising:
-
the engagement mechanism including a tab operably coupled to the top panel, the tab extending beyond the second face of the spacer block;
at least two spaced apart fingers operably coupled proximate a distal end of the tab, the fingers extending from a bottom surface of the tab and forming a gap between the fingers and the second face of the spacer block; and
the gap between the fingers operable to engage respective sides of a web on an I-beam support post and the gap between the fingers and the second face of the spacer block operable to engage respective sides of a flange on the I-beam support post.
