Abstract
The modular free-standing ballasted guardrail system comprises: a support foot, attachable stanchion, leverage bar, and counterweight bases. T-head bolts preferably facilitate a modular assembly process, allowing attachment of the stanchion, leverage bar, and counterweights to the foot. The counterweight bases may be made of durable material like HDPE filled with cement or water. The support foot may feature channels for slidable receipt of the stanchion and leverage bar.
Claims25
A modular free-standing ballasted guardrail system comprising:
- a support foot;
- a guardrail stanchion attachable to the support foot;
- a leverage bar attachable to the support foot;
- a counterweight base, wherein the guardrail system is configurable in:
- a first configuration wherein the counterweight base is attached directly to the support foot without the leverage bar;
- and
- a second configuration wherein the counterweight base is attached directly to the leverage bar, the leverage bar is attached to the support foot, and the counterweight base is spaced away from the support foot;
- wherein the support foot defines a stanchion engaging channel for slidable receipt of the stanchion therein;
- wherein the stanchion defines a longitudinal attachment channel engageable by means of a T-head bolt;
- wherein the stanchion engaging channel of the support foot has a proximal notch to accommodate a stem of the T-head bolt;
- and
- wherein a nut on the stem tightens against the proximal notch to lock the stanchion into the stanchion engaging channel.
