Abstract
A guardrail system for use along a roadway. The system can include a longitudinal body having one or more longitudinal void spaces formed therein, at least one substantially vertical post connected at one or both ends of the body, and a longitudinal member disposed within any one of the longitudinal void spaces of the body having a crosswise ultimate tensile strength that is at least 20% greater than the crosswise ultimate tensile strength of the longitudinal body.
Claims22
A guardrail, comprising:
- a longitudinal body made from one or more plastics, the body having at least two void spaces formed through the body from a first end of the body to a second end of the body, and
- a structural member disposed within any one of the void spaces, the structural member being metallic, wherein the void spaces are isolated from one another by the body and at least one of the void spaces is rectangular cuboid in shape, and wherein the structural member has a length substantially the same as the length of the longitudinal body.
A guardrail system, comprising:
- a longitudinal body having two or more void spaces formed therein, wherein a cross section of the longitudinal body comprises a height and a width, the height being less than the width;
- a substantially vertical post connected at one end of the longitudinal body, the post having a recessed channel formed therein, the recessed channel configured to receive at least a portion of the longitudinal body;
- and
- a structural member disposed within any one of the void spaces, the structural member being metallic, and wherein at least one of the void spaces is rectangular cuboid in shape.
1 more element
A guardrail, comprising:
- a longitudinal body made from fiber reinforced plastic;
- a first longitudinal void space formed within the body, the first longitudinal void space having a circular cross-section;
- a second longitudinal void space formed within the body, the second longitudinal void space having a rectangular cross-section having a height that is less than a width;
- and
- a structural tube disposed within at least one of the first and second longitudinal void spaces, wherein the first and second longitudinal void spaces are generally parallel and separated from one another by the fiber reinforced plastic of the body.
