ABSTRACT:
A concrete form construction unit includes a plurality of like length sections telescopically arranged. The unit is made from lightweight but rigid material, preferably aluminum, for convenience in storage and manual handling and has sections preferably of approximately ten feet in length for telescopic extension to substantial selected lengths. Multiple units can be arranged in self-aligning telescopic connection for indefinite lengths and sections can be used individually, if needed. The sections are of a C or channel shape design with suitable fastening devices for bracing and for securing the unit to a supporting surface and against relative movement of the telescopically extended section.
