Abstract:
A light-weight, cost-effective walk-through frame that facilitates movement from one scaffold section to another by a scaffolding worker is disclosed. The frame includes a plurality of substantially vertical support members, each having a bottom end and a top end; a truss structure connected to the support members; and a plurality of angled support members, each of the angled support members having a bottom end and a top end, the angled support members diverging from their top ends to their bottom ends such that each of the angled support member top ends are connected near a central region of the truss structure and each of the angled support member bottom ends are connected near the bottom ends of the plurality of substantially vertical support member bottom ends. The frame can be used in a scaffold, ensuring that the scaffold is suitable for use on projects of significant height. “Walk-through” can be facilitated through the use of a chevron-type configuration. From a project management standpoint, the system results in increased labor savings due, at least in part, to relative ease of set-up.
