<p>A form piece has a 'U'-shaped section. It serves as a prefab component for wall construction, which can be manufactured in industrial premises. It is made by deforming a slab, or strip section, of hydraulic or non-hydraulic fibre-reinforced material, not yet hard set. It is insertable in rails let into a floor slab and connectab-e connectable to similar prefab components with the aid of form profiles. Its open sides may be sealed by a slab of cement or plaster material, with firm adhesion. This permits variable and economical building, with easy adaptation to a grid plan and other local requirements.</p> |
