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.
Claims19
A guardrail for use along a roadway, comprising:
- a longitudinal body made from one or more plastics, the body having two or more longitudinal void spaces formed therein, and
- a longitudinal member disposed within any one of the longitudinal void spaces, the longitudinal member being a metallic tube to add flexibility and strength to the guardrail, wherein at least one of the longitudinal void spaces is rectangular cuboid in shape and at least one of the longitudinal void spaces is cylindrical in shape.
A guardrail system for use along a roadway, comprising:
- a first longitudinal body consisting essentially of one or more non-metallic materials, the first longitudinal body having two or more longitudinal void spaces formed therein;
- a second longitudinal body consisting essentially of one or more non-metallic materials, the second longitudinal body having two or more longitudinal void spaces formed therein;
- at least one substantially vertical post disposed between the first longitudinal body and the second longitudinal body;
- a first longitudinal member disposed within any one of the longitudinal void spaces of the first longitudinal body;
- a second longitudinal member disposed within any one of the longitudinal void spaces of the second longitudinal body, wherein the first and second longitudinal members are flexible and made from one or more metals, the first and second longitudinal members having a greater tensile strength than first and second longitudinal bodies;
- and
- a splicer disposed within the first and second longitudinal members and configured to connect to the at least one substantially vertical post, such that when a force is imparted on the longitudinal bodies, the longitudinal members transfer the load of the force through the splicer to the post.
A guardrail for use along a roadway, comprising:
- a longitudinal body made from fiber reinforced plastic;
- at least two longitudinal void spaces formed within the body, wherein the longitudinal void spaces are non-concentric to each other and at least one of the longitudinal void spaces is rectangular cuboid in shape and at least one of the longitudinal void spaces is cylindrical in shape;
- and
- a structural member housed within any one of the longitudinal void spaces, the structural member made from one or more metals to add flexibility and strength to the guardrail.
