TITLE

DISPOSABLE VENTILATED FORMWORK WITH FACING PANELS

DESCRIPTION

The present patent relates to modular disposable formworks that can be assembled, and in particular it concerns a new disposable modular formwork with facing panels with ventilated external panel.

Disposable formworks used to make walls or partitions in concrete in general are known.

Full-height disposable formworks are known, comprising two facing walls made of expanded material, with vertical reinforcing rods embedded within the walls themselves and transverse reinforcing rods that hold the walls together, to counteract the thrust on the walls themselves during the casting of concrete.

These formworks must be installed already assembled, with considerable storage, transport and handling problems.

Modular disposable formworks are also known, each module comprising a pair of facing panels of modular dimensions, where said panels are joined together by means of spacers fixed between the panels under construction.

Disposable modular formworks are also known, each module comprising a pair of facing panels of modular dimensions, with spacers that can be positioned directly on site.

The panels of said known modular disposable formworks are generally made of insulating material, typically of expanded material.

Disposable formworks are known consisting of two facing walls in insulating material of vegetable origin, such as for example wood cement, mineralized wood fibers.

Disposable modular formworks with facing panels are known comprising spacers for joining said panels and inserts for the insertion of said spacers, said inserts being incorporated into the thickness of said panels. Each insert includes a seat for the insertion of the engagement edge of a spacer, said seat comprising at least two housings at different depths with respect to the surface of the panel.

Thanks to said double housing, it is possible to assemble the same spacer in different ways, creating, with the same spacer, formworks with different overall thicknesses.

Each of said panels comprises elements for connection with overlying or underlying panels.

Said connection elements are present on the upper and lower edges of the panels and comprise for example two rows of protrusions and recesses, arranged alternately and staggered on the two edges.

Said protrusions and recesses are for example V-shaped, with the vertex oriented towards the outside of the panel and sides oriented towards the parallel row, and where the ends of said sides of said protrusions and recesses touch or are close to each other.

Said protrusions and recesses thus shaped confer not only the advantage of effectively assembling two superimposed panels, but also that of preventing the escape of the concrete between two superimposed panels during casting.

The subject of the present invention is a new type of disposable modular formwork with facing panels with a ventilated external panel.

The aim of the present invention is to provide a disposable formwork with high insulating power and at the same time with improved thermal behavior, particularly in the summer period, thanks to the ventilated external panel, ie the panel suitable for forming the external side of the wall.

Using the new disposable formwork it is possible to create structures with excellent thermal insulation, thermal inertia, acoustic insulation and mechanical resistance characteristics.

Another important object of the present invention is to contain construction and management costs on site.

Another object of the present invention is that of being able to be made in separate parts, which can be assembled on site, in whole or in part.

Another purpose of the present invention is to be able to store, transport and handle the separated parts with limited overall dimensions.

Another purpose is to allow total flexibility of use, since the new formwork is completely modular, thus allowing to create assembled formworks by varying the thickness of the external panel and / or of the internal panel, according to the project requirements, and also allowing the '' application or installation of any coating on the external surface of each panel.

These and other direct and complementary purposes are achieved by the new disposable modular formwork with facing panels, for the construction of reinforced concrete structures, comprising a pair of facing panels and in any case connected to each other, for example by means of spacers, where one of said panels comprises one or more cavities or ventilation channels obtained in the thickness of the panel itself, in any case arranged in a direction substantially parallel to the major faces of the panel and suitable for forming a ventilated wall.

Said panel with integrated ventilation channels, or ventilated panel, is adapted to substantially form the outer side of the wall to be made.

In the preferred solution, said external ventilated panel comprises a plurality of said ventilation channels, preferably all arranged parallel to each other and oriented for example parallel to the lateral sides of the panel, i.e. vertically once installed, or parallel to the upper and lower edges, that is horizontally once installed, or generally inclined.

This network of ventilation channels ensures ventilation inside the outer panel of the formwork, in order to dehumidify the structure and therefore to improve the insulation efficiency.

Said panels are conveniently made of insulating material, for example ESP, high density sintered expanded polyester.

In the preferred solution, said two facing panels are connected to each other by means of spacers, made of plastic and / or metal material, bound to the panels themselves.

For example, said spacers comprise tie rods with shaped edges embedded directly in the thickness of the panels, or said edges are constrained by inserts or guides, preferably of the multi-section type, or each equipped with two housings at different depths with respect to the surface of the panel, in order to assemble the formworks obtaining different overall thicknesses, also obtained in various ways by combining internal and external panels of different thickness.

Said panels further comprise elements for connection with corresponding superimposed panels.

For example, said elements for the connection comprise protrusions and recesses obtained on the upper and lower edges of the panels, in alternate and staggered positions on the two opposite edges, to allow the interlocking of two superimposed panels.

The characteristics of the new formwork will be better clarified by the following description with reference to the drawing tables, attached as a non-limiting example.

Figure 1 shows in plan an example of the new formwork (C) with facing modular panels (PI, P2).

Figure la-a shows a section of the external panel (P2) of the formwork (C), i.e. of the panel (P2) suitable for forming the external side of the structure, drawn according to the section line a-a in figure 1.

Figure 2a shows in plan an example of the new formwork (C) with panels (PI, P2) bound together by means of spacers (D) comprising shaped edges (DI) directly embedded in the thickness of the panels (PI, P2).

Figure 2b shows in plan an example of the new formwork (C) with reliefs (R) and recesses (S) on the opposite upper and lower edges (Pu, Pd) of the panels (PI, P2), for the connection with panels ( PI, P2) superimposed.

The new formwork (C) comprises two modular panels (PI, P2) adapted to be placed facing each other and substantially parallel and connected to each other, preferably by means of spacers (D), for example of the type shown in Figure 2a.

Said spacers are able to be fastened to said panels (PI, P2), for example with edges (DI) embedded directly in the thickness of the panels PI, P2).

Alternatively, said edges (D1) are able to be constrained by insertion into corresponding inserts (S) incorporated in the thickness of the panels (PI, P2), visible in figure 1.

Each insert (S) comprises for example a seat (SI) open on the surface (Pi) of the panel (PI, P2) facing the facing panel (P2, PI), and where said seat (SI) of said insert (S) it includes at least two housings (S2, S3) at different depths inside the panel (PI, P2). By installing the spacer (D) in one or the other of said housings (S2, S3) of the two facing panels (PI, P2), a formwork (C) of different thickness is thus obtained.

Each of said panels (PI, P2) further comprises, on the upper and / or lower edges (Pu, Pd), elements for connection with the overlying and underlying panels (PI, P2). Said elements comprise, for example, walls, reliefs and / or corresponding depressions, suitable for making the joint or alignment between two superimposed panels, also preventing the escape of concrete.

In a possible embodiment, schematized in figure 2, said elements for the connection comprise two or more parallel longitudinal rows of reliefs (R) and recesses (S) alternating for example in a checkerboard pattern, arranged inverted and staggered on the two edges (Pu, Pd ) opposite, as schematized in figure 2b.

In the solution of Figure 1, for example, said protrusions (K1) and recesses (K2) are V-shaped, with vertex (K3) oriented towards F and sternum of the panel (PI, P2) and sides (K4) oriented towards parallel row.

The external panel (P2), that is the panel (P2) suitable for forming the external side of the wall to be made, comprises one or more cavities or ventilation channels (W) obtained in the thickness of the panel (P2) itself and suitable for creating a ventilated wall.

In the preferred solution, schematized in figures 1 and la, said external ventilated panel (P2) comprises a plurality of said ventilation channels (W), preferably all arranged parallel to each other and oriented parallel to the lateral sides (Pf) of the panel (P2) , i.e. vertically once they have been installed.

Said channels (W) are pass-through, i.e. they have openings (Wl) on the upper (Pu) and lower (Pd) opposite edges of the panel (P2) to allow ventilation of the wall.

Said openings (Wl) are obtained in corresponding modular positions on said edges (Pu, Pd), for the exact correspondence with the openings (/ wl) of the ventilation channels (W) of the superimposed panels (P2).

In figure 1 and la, said channels (W) are for example full height, ie said openings (Wl) are formed on the upper and lower edges (Pu, Pd) of the panel (P2).

In a possible alternative solution, not shown in the figures, said ventilation channels (W) are oriented orthogonally to the lateral sides (Pf) of the panel (P2) and are full length, i.e. said openings (Wl) are obtained on said lateral sides (Pf) opposites of the panel (P2).

In a possible alternative solution, not shown in the figures, said ventilation channels (W) are oriented generally inclined with respect to the lateral sides (Pf) of the panel (P2).

These are the schematic modalities sufficient for the skilled person to realize the invention, consequently, in concrete application there may be variations without prejudice to the substance of the innovative concept.

Therefore, with reference to the above description and the attached tables, the following claims are expressed.
