ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to building construction and more particularly to the construction of building walls, both inside and outside ones.
The invention is concerned with formworks for building walls, as well as with multi-layer panels for realizing such formworks, and with a method for building walls.
The invention is preferably applicable, but not limited to, (load) bearing walls, by using disposable formworks elements, formed as multi-layer panels that are dry-assembled.
BACKGROUND ART
The known methods of constructing walls in building and civil engineering works require a large amount of labour, particularly in the finishing stage. On the other hand prefab constructions have rigid design and require an assembling apparatus that is not always available in medium and small building yards.
OBJECT OF THE INVENTION
It is an object of the present invention to provide improved formwork elements and a method of constructing building walls by using such formwork elements that involves a labour saving by reducing as much as possible the carpentry costs and the wall-finishing costs, while at the same time allowing the design and constructive flexibility deriving by the use of bricks.
These objects are accomplished through a formwork, a multi-layer panel and a method for building a wall as claimed in claims

,

and
9
, respectively. Further advantageous features of the invention are recited in the dependent claims.
DISCLOSURE OF THE INVENTION
According to a first aspect the invention consists of a formwork for building walls by using basic multi-layer elements to be manufactured at a factory that are finally incorporated in the concrete pouring, such elements forming the inside and outside facings and being firmly secured to the building skeleton with the associated safety advantages in respect of seismic events.
Such formwork is formed by a plurality of pairs of facing panels connected together so as to form an internal space between them, with pairs of facing panels arranged in superimposed rows, and the panels of each pair being connected to each others by braces of adjustable length. Both the braces and the panels are left in the wall formed after a cementitious material poured in said inside space has set.
According to a second aspect, the invention consists in a multi-layer panel for building walls comprising two or more layers of material, one of which is adapted to form the facing of the finished wall, and the other is formed by a slab or sheet of a rigid insulating material, with a plurality of interposed spacing members or ribs connecting the two layers so as to define channels therebetween.
According to a third aspect, the invention consists of a method for building walls by using such formwork elements.
