Abstract
Abstract A sectional nog structure for fastening a covering element to a foamed plastic slab (5, 6, 35, 39, 49, 54) comprises at least one insert (2, 3), flush-insertable in the slab (5, 6, 35, 39, 49, 54) and associated with a tierod (4), having a base (10) accessible from the outside of the slab and constituting respective means for fastening to the slab (5, 6, 35, 39, 49, 54) the chosen covering element. Advantageously, this sectional nog structure allows to manufacture composite and modular construction elements, such as for example lost formworks and panels incorporating at least one foamed plastic slab and being able to support any covering element.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
150 words
A construction assembly for manufacturing walls for buildings, comprising: a pair of plastic slabs spaced by at least one sectional nog for fastening a covering element to at least one of said plastic slabs, said nog comprising: at least a pair of opposite inserts, made of a heat-insulating material, mutually connected at a predetermined distance by at least one tierod having a substantially smooth outer surface and flush-insertable in said pair of plastic slabs; adjusting means for adjustably engaging at least one of said inserts on one end of said tierod, so as to axially regulate the position of said at least one insert within said at least one plastic slab; and cover fastening means for fastening a cover projecting from said at least one of said inserts, said cover fastening means being accessible from an outside surface of said at least one plastic slab for fastening said covering element.
Claim 2
Dependent Claim
150 words
A construction assembly for manufacturing walls for buildings, comprising: a pair of plastic slabs spaced by at least one sectional nog for fastening a covering element to at least one of said plastic slabs, said nog comprising: at least a pair of opposite inserts, made of a heat-insulating material, mutually connected at a predetermined distance by at least one tierod having a substantially smooth outer surface and flush-insertable in said pair of plastic slabs; adjusting means for adjustably engaging at least one of said inserts on one end of said tierod, so as to axially regulate the position of said at least one insert within said at least one plastic slab; and cover fastening means for fastening a cover projecting from said at least one of said inserts, said cover fastening means being accessible from an outside surface of said at least one plastic slab for fastening said covering element.
