Abstract
Abstract A building element for the production of internal and external walls, parapets, fences, sheathings, and the like includes two flat boards joined by bars, and tongue elements. The dimensions of the elements are coordinated to permit many different ways of assemblage of the flat boards in order to form prefabricated building elements which are designed for specific purposes.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
253 words
A building assembly for the production of dismountable internal and external walls, fences, parapets, sheathings, and the like; said building element comprising: two elongate parallelly extending flat boards of the same size; at least two plates extending transversely of and fixed to said two flat boards to space said two flat boards from each other to form an entity; each said plate having first and second opposite edge surfaces fixed to respective of said flat boards; each said plate having a third edge surface at a first position spaced by a first given distance from first longitudinal edges of said two flat boards; each said plate having a fourth edge surface, opposite to said third edge surface, at a second position spaced by a second given distance from second longitudinal edges of said two flat boards; each said plate being formed of a single element between said respective first and second positions; said first given distance being equal to said second given distance; a tongue element insertable between said two flat boards in a position to contact one of said third and fourth edge surfaces of each of said plates, the breadth of said tongue element being equal to twice said first given distance and equal to twice said second given distance; and the distance between the end surfaces of said two flat boards and the surfaces of said plates parallel and adjacent to said end surfaces of said two flat boards being equal to one half the breadth of said tongue element.
