ABSTRACT:
A guardrail system and method comprises utilizing at least one through-hole of a poured concrete wall of a structure to affix a stanchion to the wall inside a bay of the structure. The stanchion allows for a guardrail to be conveniently and securely positioned within the bay without damage to the structure and without covering an edge of the structure. A fastener inserts through the through-hole which is preferably a pre-existing tie-hole resulting from formation of the wall. In one optional aspect a guardrail stanchion includes a base segment having at least two slots for receiving fasteners which insert through two tie-holes of the wall, and at least one side segment having at least one adjustment port, the side segment extending generally perpendicular to the base segment. A pair of stanchions may be affixed to opposing walls within the bay, and guardrails affixed thereto and spanning across the bay. The system may also include a cable system having a cable operate as a guardrail to be tightened by utilizing a stanchion in accordance with the invention.
