impalcature

Impalcature is a temporary framework used in construction, maintenance, and repair work to provide access to elevated areas and to support workers, tools, and materials. It is designed to be assembled, disassembled, and repositioned as the project advances, and its primary goal is to improve safety and efficiency when working at height. Impalcature can take several forms, but all share the common function of creating a stable working platform above ground level.

Most impalcatura consists of vertical uprights (standards), horizontal ledgers and transoms, diagonal braces for stability, and platforms or planks. Base support devices such as base plates or mudsills help distribute weight, while ties or anchors secure the structure to the building or a supporting scaffold to prevent tipping. Guardrails, toeboards, and proper access ladders are commonly included to protect workers.

Common configurations include supported scaffolds, which rest on the ground or structure; suspended scaffolds that hang from overhead supports; and rolling or mobile towers that can be moved on site. Materials range from steel and aluminum to wood planks for platforms. Safety and compliance requirements, including load ratings, regular inspections, and training, are enforced in many jurisdictions by standards such as OSHA regulations in the United States or EN 12811 in Europe.
