Stiffening device of a rectilinear element in the expanded polystyrene for the embodiment of the flaps

摘要

The device has a T-shaped cross-section rod (4) embedded in fittings of a mortise (1a) formed in thickness and on a part of length of an expanded polystyrene rectilinear element i.e. post (1), where the mortise receives slats (3). The fittings are constituted of a groove (1b) formed in a median part and in bottom of the mortise. The groove receives a vertical branch (4a) of the rod. The rod rigidifies the rectilinear element that forms a side of a framework of a leaf in the form of a shutter.
