Abstract
Abstract In the construction arrangement of building composite double or multiple walls, two or more load-bearing walls are built together by means of panels which are prefabricated of concrete or other strong hardenable material and of noncorrodible molds of various shapes that can be combined in various ways and which remain integrated in the final construction assembly. All the elements of the construction are of such size and weight that can be easily handled by two laborers without the need of special or heavy equipment. The separation between walls is pre-determinable in accordance with the specifications of the construction and the space between walls is fillable with any material suited to the purpose of the construction, which remains fireproof regardless the material used as filler. The composite walls can be fabricated with capability for bearing permanent overloads.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
163 words
An improved composite wall comprising the combination of: a first generally flat vertical wall formed of a plurality of first planar panels arranged with the panel edges fitted together along horizontal edges; a second general flat vertical wall formed of a plurality of second planar panels arranged with the panel edges fitted together along horizontal edges; said first and second walls being horizontally spaced from each other forming an aperture therebetween for receiving insulation; a pair of one piece vertical elongated columns arranged in parallel and spaced from one another forming an aperture between facing column sides; vertical elongated outwardly opening channels positioned on opposite faces of each of said columns and positioned for receiving end edges of a plurality of the planar panels which comprise said first and second walls; said apertures between said first and second walls and between said columns combining to form a continuous aperture extending along said walls and columns; and vertically spaced connecting members attaching columns together.
Claim 2
Dependent Claim
