PERMANENT INSULATING FORMWORK WITH JOINING FRAMES
A permanent insulating formwork is made by piling up rows of insulating panels (2a, 2b) and placing junction frames (1) in between two stacked rows. The joining frame (1) is rectangular and comprises vertical wings (16e, 16e', 16i, 16i', 17a, 17a', 17b, 17b') on the periphery thereof. The outer surfaces of the panels rest against the inner surfaces (25e, 25i) of the wings in order to keep the distance between panels constant. The invention can be used in the construction of building walls made of concrete.
