Abstract
An anchorage assembly (100) is interconnected between a support structure (90) and a safety line (160, 161). The anchorage assembly (100) routes the safety line (160, 161) about a comer and accommodates passage of a slotted coupling device movably mounted on the safety line (160, 161).
Claims20
A method of routing an intermediate portion of a safety line about a corner on a support structure while accommodating passage of a slotted coupling member along the safety line, comprising the steps of:
- disposing at least two energy absorbers between the support structure and a first curved plate;
- securing the first curved plate to the support structure;
- disposing at least two energy absorbers between the first curved plate and a second curved plate;
- securing the second curved plate to the first curved plate;
- securing at least three line supporting brackets to the second curved plate;
- securing the safety line to the brackets;
- and
- securing the coupling member to the safety line.
An anchorage assembly for routing an intermediate portion of a safety line about a corner of a support structure while accommodating passage of a coupling device, comprising:
- a first curved plate having a convex side and a concave side;
- an energy absorber disposed adjacent the concave side proximate each end of the first curved plate;
- an energy absorber disposed adjacent the convex side proximate each end of the first curved plate;
- a second curved plate having a convex side and a concave side, wherein the concave side of the second curved plate is arranged to face the convex side of the first curved plate, and the second curved plate is bolted to the first curved plate;
- and
- a plurality of line supporting brackets anchored relative to the second curved plate, wherein the brackets are relatively more rigid than the energy absorbers.
In combination, a support structure having a corner, a horizontal safety line supported by at least three brackets, and an anchorage assembly interconnected between the brackets and the support structure, the improvement comprising:
- at least one plate configured to curve about the corner of the support structure with a first end of the plate extending in a first direction and a second end of the plate extending in a discrete, second direction, wherein a first one of the brackets is supported proximate the first end of the plate, and a second one of the brackets is supported proximate the second end of the plate, and a third one of the brackets is supported proximate an intermediate portion of the plate;
- and
- a first energy absorber secured between the support structure and the first end of the plate, and a second energy absorber secured between the support structure and the second end of the plate.
An anchorage system for routing a horizontal safety line about a corner on a support structure, comprising:
- a first curved plate having a concave side and a convex side;
- a second curved plate having a concave side and a convex side;
- a third curved plate having a concave side and a convex side;
- first energy absorbers disposed adjacent the concave side of the first curved plate;
- first fasteners having respective leading ends inserted through the first curved plate and through respective first energy absorbers;
- second energy absorbers disposed between the convex side of the first curved plate and the concave side of the second curved plate;
- second fasteners extending through respective second energy absorbers, and interconnected between the first curved plate and the second curved plate;
- third fasteners interconnected between the second curved plate and the third curved plate;
- and
- line supporting brackets secured to the third curved plate by respective third fasteners.
