DISCARDABLE FORMWORK FOR COLUMNS

摘要

The formwork is comprised of a tubular core or body based on a plurality of polystyrene pieces (3-7) fixed to each other by means of adhesive at their union edges (5); the tubular core is internally coated with a plastic sheet (1) or rigid plates (11, 11') made of wood which has been plastified on their internal face or made of rigid plastic material and fixed to each other at their internal face by means of adhesive strips forming an impervious barrier; on the external side, said assembly is complemented by a lattice support consisting of a glass fiber mesh (6-18) which has been wound helically around the tubular core (3-7) and fixed to the latter by means of adhesive (7-19) so that said mesh confers to the assembly the required mechanical strength. Optionally, it is possible to set on the mesh envelope (6) a self-adhesive sealing strip (8) forming a decorative element and a publicity support for the formwork.
