Description

The present invention relates to a method for making a constructional sandwich panel for high strength wall and covering assemblies.
Vertical dividing panels and horizontal covering panels, for use in the civil, industrial, ship, railroad fields and the like, comprising a pair of plate-like elements coupled in a parallel relationship with one another are already known.
The connection of said plate-like elements is carried out by arranging between the two plate-like elements a further construction element, usually made of an undulated sheet metal material.
This sheet metal material, in particular, has a surface extending through the overall surface of the plate-like elements and has a substantially sinusoidal profile cross-section, i. e. a cross-section profile including a plurality of cascade arranged peak and valley portions.
The sinusoidal surface element is contact engaged with the plate-like element surfaces and is adhesively bound to said surfaces, by using, for example, glue or adhesive materials.
This construction method, while has been found very unexpensive, has, Showever, the disadvantage 0:i; 2o ooo0 2 that the sinusoidal surface element provides a small contact area for contacting the plate-like elements at each peak and valley of its waved or undulated profile.
This small contact area prevents the thus assembled panel from having a long duration or useful operating life.
Likewise, the provision of curved surfaces contacting the surfaces of the platelike elements of the panel, causes the assembled panel to have a comparatively poor mechanical strength.
The document FR-A-1024889 discloses a constructional sandwich panel including a corrupted sheet element, or fretted element, made by rotary shaping rollers.
SUMMARY OF THE INVENTION Accordingly, the aim of the present invention is to provide a method for making a constructional sandwich panel for use in civil, industrial, ship, railroad fields and the like, which has a very high mechanical strength.
According to one aspect of the present invention, the above aim is achieved by the present invention, which provides a method for easily making a very high mechanical strength panel, for vertical dividing and horizontal covering assemblies, as well as for walls for supporting finishing elements, such as marble elements, laminated elements, tiles, fabric coverings, linoleum coverings or the like, according to claim 1.
2) The panel can comprise two plate-like elements, coupled to one another in a substantially eo o:"f r oe^ *ee •Hl parallel relationship, as well as a fretted element, arranged between said two plate-like elements for connecting said plate-like elements by gluing the parallel surfaces thereof.
The mentioned constructional panel, in particular, can be made with different thicknesses, depending on the construction of the punch element for making the fretted element, and depending on the used materials for forming both the plate-like element and the fretted element.
The method comprises a gluing step which can be performed by a simple cold stacking operation, or by a hot gluing operation performed in a press type of oven, including two metal sliding belts driven by driving rollers.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following disclosure reference will be made to some preferred embodiments of the present invention which have been illustrated as a not limitative example of several possible variations of the invention.
Figure i, in particular, shows a constructional panel, generally indicated by the reference number 1, comprising a first plate-like element 2 and a second plate-like element 4.
Said plate-like elements can be made of an aluminium material, or of a black or galvanized metal sheet elements, as well as of stainless steel elements, laminated elements or any other suitable alloy element.
Said plate-like elements are coupled to one another with a substantially parallel relationship, a fretted element 3 made of aluminium, black or galvanized sheet metal, stainless steel, laminated materials or alloyed materials being arranged and glued between said plate-like elements.
In this connection it should be pointed out that, for inventive purposes, the term "fretted element" is intended for indicating an element, for example made of a sheet metal material which, through its cross section, presents a profile or contour including a plurality of horizontal portions, corresponding to peaks and valleys of said profile, and joined by a plurality of portions angled with respect to said horizontal portion, so as to form a series of trapezium patterns.
The fretted element 3 is applied, by its horizontal surfaces, to contact the platelike elements 2 and 4, in order to connect said plate-like elements by glue.
More specifically, the plate-like elements 2 and 4 are glued to the fretted element 3 by a glue which would depend on the elements to be bound.
Figure 2 illustrates a modified embodiment of the present invention, in which the constructional panel 1 is provided moreover with a melamine laminate material platelike element Actually, said laminated element can be directly glued to said fretted element, or it can be glued to one of the plate-like elements, depending on the mechanical strength properties to be achieved in the finished panel.
The constructional sandwich panels made by the method according to the ooooo3 present invention can also be connected to one another, according to any desired connecting angle, depending on the constructional or finishing requirements to be achieved.
20 Furthermore, the constructional panels can also be finished by applying on their perimetrical 2 ooo WO 01/09455 PCT/IT99/00249 8 edge portions a profiled element in order to conceal the fretted pattern, to provide a finished flat surface.
A first type of the mentioned connection patterns of said panels is shown in figure 3, where a pair of constructional panels have been connected along the same connecting line by a first profile or section member 6.
A second type of connection for connecting said panels comprises a right angle type of coupling, obtained by using a second profile 7.
In these connections, the laminated element if provided, can be arranged inside the right angle or outside thereof.
The profile 7 is provided with angled portions 16 and 17 allowing panels to be engaged therein for forming the right angle.
A third type of panel connection comprises an obtuse angle panel connection, made by using a third profile 8.
In this connections too, the laminated element 5, if provided, can be arranged inside the obtuse angle or outside thereof.
The profile 8 is provided with angled portions 18 and 19 allowing panels to be engaged therein according to a desired obtuse angle, as shown in Figures 5-6.
A further connection pattern for angle connecting said panels, provides to use a plastic material 20, to be applied at the outer corner of said angle, so as to mutually connect said panels, upon curing said plastic material, as shown in Figure 7.
WO 01/09455 PCT/1T99/00249 9 The angle of Figure 7 (the inner angle exposed to the view) is obtained by vertically cutting the outer plate-like element, and then bending the constructional panel by providing an opening outside of the panel, while assuring the continuity of the inner plate-like element.
Then, a plastic material 20 is applied, which, at the end of the process, will provide the obtained angle with high strength properties.
Figure 16 shows the outer angle obtained by milling the inner plate-like element while holding the continuity of the outer plate-like element, with a subsequent bending and casting of the plastic material in order to provide an angle having the above disclosed features.
Figure 8 illustrates an angled pattern comprising a constructional panel, generally indicated by the reference number 30, which, by milling the inner plate-like element and bending it, but without casting any plastic materials, but merely putting in an adjoining relationship the milled elements, will provide a curved element including an uninterrupted outer plate.
Figure 9 illustrates another embodiment of the constructional panel according to the present invention, which comprises a further fretted element 3' and a further plate-like element to provide the panel with a large thickness and a greater strength.
Likewise, Figure 17 illustrates another embodiment of the subject constructional panel, including a further fretted element perpendicular to the first fretted element 3, as well as a further plate-like element separated by a plate-like element 84.
Figure 14 is a perspective view illustrating a constructional panel having the constructional or structural skin thereof, formed by the plate-like elements 2 and 4, only on a side thereof, so as to allow the panel to be easily bent.
In this case, consequently, the fretted element 3 will be glued to the plate-like element 4.
Figure 15 is a perspective view of a constructional panel, according to a preferred embodiment of the invention, to which an outer bent profile 80 has been connected.
Figure 18 is a cross-sectional view of a constructional panel having different size flat portions, to allow said panel to be bent according to small bending radii, as clearly shown in Figure 19.
Finally, during the making of the subject constructional sandwich panels, it would be moreover possible to embed profiles or section members, or materials allowing the panel to be used without the need of re-contouring it.
The panel 1 made by the method according to the present invention has very long duration properties, since the plate-like elements are glued by exploiting the ooooi S surfaces of the fretted element parallel to said plate-like elements.
Thus, a very broad gluing surface, and, consequently, a greater stability and life of the panels, will be obtained.
2 In addition, the provision of flat surfaces contacting the plate-like elements of the panel will 11 provide said panel with very high strength properties.
The inventive method, in particular, comprises a first step of forming the fretted element 3, by beating a sheet metal element by a beating tool 42, having a mated configuration or shape.
In particular, with reference to Figure 10, the fretted element is unwound from a roll 40 and fed, in a flat form 41, to the tool 42 which will perform a plurality of subsequent beating operations on the flat sheet metal element 41, to deform it according to the fretted contour or profile 43.
Finally, the fretted element is wound on the roll 44.
This method is fully automatized, the aligning and feeding operations included.
In particular, the flat profile 41 is deformed by the beating tool 42, comprising a first element, having a fretted profile portion 50, and a second element, also provided with a fretted profile portion 51, mating, within set tolerances, the mentioned fretted profile portion 50 of the first element.
By using the disclosed beating tool 42, the fretted profile 43 can be easily made by simple beating operations.
The constructional panel can be made with different thicknesses, depending on the beating or punching tool 42.
*29*
*S
WO 01/09455 PCT/IT99/00249 12 A punching or beating tool having a configuration different from that of the tool shown in Figure 11 is shown in Figure 13.
The method comprises, moreover, a second glueing step in which the plate-like elements 2 and 4 are glued on the fretted element 3.
In this connection it should be apparent that the method can be changed depending on the used material or glue; in particular, it can be carried by simple cold pressing operations on a stacked arrangement, whereas, in a second case, it can be carried out by hot glueing and pressing operations performed in a tunnel including two metal belts entrained by driving rollers, as well as a pressing device on the top portion of the tunnel.
The motorized or driven roller belt can be driven in opposite directions.
