Description
METHOD OF ASSEMBLING FACING PANELS WITH A DOUBLE-GLAZING- TYPE STRUCTURE
TECHNICAL FIELDS
The present invention relates to a method of assembling facing panels with a double-glazing-type structure.
More specifically, the present invention relates to a method of assembling facing panels, with a double- glazing-type structure, for making doors and windows for ships and/or for facing building facades, to which the following description refers purely by way of example.
BACKGROUND ART As is known, facing panels with a double-glazing- type structure for facing building facades comprise two rectangular glass sheets glued to opposite sides of a spacer frame to form an air-filled gap between the glass sheets; and a peripheral frame made of plastic or metal and glued firmly to the glass sheets with silicone glue.
More specifically, the spacer frame shape is roughly the same, but slightly smaller, as the rectangular shape of the peripheral edge of the glass sheets, so that, once
glued to the spacer frame, the glass sheets form with it a rectangular flat body having a lateral, peripheral, square-section groove extending seamlessly about the whole perimeter of the flat body and bounded laterally by the projecting lateral edges of the two glass sheets.
The peripheral frame comprises four straight sections, with a complex cross section, which are fixed end to end to one another to form the four sides of a rectangle. Each section obviously rests on a corresponding lateral edge of the flat body, to cover the relative peripheral groove portion, and is secured firmly to the two glass sheets and the spacer frame with silicone glue injected inside the peripheral groove of the flat body. To prevent detachment of either one of the glass sheets from the peripheral frame as a result of accidental breakage of the other sheet and/or deterioration of the silicone glue, each of the four sections of the peripheral frame has a tab or projecting rib which projects from the main body of the section and firmly engages the peripheral groove of the flat body to interfere mechanically with the edge of the flat body formed by the two glass sheets and the spacer frame. Obviously, the tab or projecting rib is also secured firmly to the two glass sheets and the spacer frame by filling the peripheral groove of the flat body completely with silicone glue.
Because of the tab or projecting rib on each of the
four sections of the peripheral frame, facing panels of the above type are assembled using a method comprising the steps of :
- placing two rectangular glass sheets on opposite sides of a rectangular spacer frame to form a flat body having a double-glazing-type structure, and a lateral peripheral groove extending seamlessly about the whole perimeter of the flat body and bounded laterally by the projecting lateral edges of the two glass sheets; - pressing the two glass sheets against the spacer frame;
- applying a chemical product or "primer" manually to the surface of each of the four sections to ensure optimum adhesion of the silicone glue to the surface of the section;
- fitting the four sections of the peripheral frame of the panel separately to the four sides of the flat body, so that the tab or projecting rib of each section engages the peripheral groove of the flat body; - fixing the ends of the four sections of the peripheral frame of the panel rigidly to one another to form a rigid structure; and
- injecting a suitable amount of silicone glue into the peripheral groove of the flat body to secure the four sections of the peripheral frame of the panel firmly to the flat body defined by the two glass sheets and the spacer frame .
Obviously, applying "primer" and the presence of the
tabs or projecting ribs on the sections make painstaking work of assembling the peripheral frame to the flat body- defined by the two glass sheets and the spacer frame. Each of the four sections of the peripheral frame of the panel, in fact, must be fitted to the corresponding side of the flat body separately from the others , by moving the section in a direction coplanar with the lying plane of the flat body and the peripheral groove of the flat body, and making sure the respective tab or projecting rib is also kept perfectly coplanar with said lying plane to permit correct insertion of the tab or projecting rib inside the peripheral groove.
As stated, the ends of the four sections of the peripheral frame of the panel must be fixed later, either just before or just after injecting the silicone glue into the peripheral groove of the flat body.
In addition to the above problems, fitting the four sections to the four sides of the central flat body calls for constant supervision by a skilled worker, and cannot be done fully automatically, with all the drawbacks this entails in terms of manufacturing cost and time, chemical surface pollution caused by overhandling the component parts, and quality control.
DISCLOSURE OF INVENTION It is an object of the present invention to eliminate the above drawbacks of currently used methods of assembling facing panels with a double-glazing-type structure for facing building facades and similar.
According to the present invention, there is provided a method of assembling facing panels for facing building facades, as claimed in Claim 1 and preferably, though not necessarily, in any one of the following Claims depending directly or indirectly on Claim 1. BRIEF DESCRIPTION OF THE DRAWINGS
A non-limiting embodiment of the present invention will be described by way of example with reference to the accompanying drawings, in which: Figure 1 shows a section, with parts in section and parts removed for clarity, of a facing panel, with a double-glazing-type structure, produced using an assembly method in accordance with the teachings of the present invention; Figures 2 to 6 show schematics of steps in the method, according to the teachings of the present invention, of assembling facing panels with a double- glazing-type structure.
BEST MODE FOR CARRYING OUT THE INVENTION Number 1 in Figure 1 indicates as a whole a facing panel, wi-th a double-glazing-type structure, specially designed for facing building faςades and/or for making doors and windows, railings, self-supporting windows and similar for ships. Panel 1 substantially comprises a preferably, though not necessarily, rectangular panel or central flat body 2 having a double-glazing-type structure and a preferably, though not necessarily, square-section lateral peripheral
groove 2a extending seamlessly about the whole perimeter of flat body 2 and coplanar with the lying plane P of flat body 2 ; and a peripheral frame 3 extending about the whole peripheral edge of flat body 2, at peripheral groove 2a, and fixed firmly and irremovably to flat body 2 with structural silicone glue 4, or similar, applied along the whole of, and completely filling, peripheral groove 2a.
More specifically, flat body 2, with a double- glazing-type structure, comprises a central spacer frame 5 made of metal, plastic or other rigid material, and coplanar with lying plane P of flat body 2; and two lateral sheets 6 and 7 of glass, plastic, marble, metal or other rigid material, which are placed, parallel and facing each other, on spacer frame 5, on opposite sides of lying plane P, to form peripheral groove 2a on the outside of spacer frame 5, and, on the inside of spacer frame 5, a closed central cavity filled with air or other inert gas for insulating purposes. In other words, spacer frame 5 negatively reproduces the shape of the perimeter of flat body 2 at the bottom of peripheral groove 2a,- while sheets 6 and 7 extend parallel to lying plane P of flat body 2, and are designed to project beyond the outer lateral side of spacer frame 5 by a predetermined length 1$, I7 along the whole perimeter of spacer 5, so as to laterally define peripheral groove 2a.
In addition, the glass sheet 6 eventually facing
outwards of the building - hereinafter also called the outer sheet 6 - is designed to exactly reproduce the shape of the peripheral edge of flat body 2; while the glass sheet 7 eventually facing inwards of the building - hereinafter also called the inner sheet 7 - is designed so that its peripheral edge projects beyond the outer lateral side of spacer frame 5 by a length I7 smaller than length Ie of outer sheet 6.
With reference to Figure 1, peripheral frame 3 comprises a number of straight and/or curved sections 8, which have complex cross sections, are preferably, though not necessarily, formed in one piece, are made of metal, plastic or other rigid material, and are fixed end to end to one another to form a rigid supporting frame 8 lying in a plane parallel to lying plane P of flat body 2, and which, once assembled, is designed to fit onto, and cover the whole peripheral edge of, inner sheet 7.
More specifically, peripheral frame 3 comprises a number of sections 8 which, once fixed end to end to one another, form a rigid supporting frame 8 having an inner annular flange 8a, which projects from the main body of and towards the centre of the supporting frame, and, with the interposition of soft-rubber peripheral seals, rests on the surface of the exposed face 7a of inner sheet 7 - i.e. the surface of the face of inner sheet 7 eventually facing inwards of the building - so as to keep the front surface 8b of rigid supporting frame 8 - i.e. the surface of the supporting frame facing inwards of peripheral
groove 2a and eventually directly contacting structural glue 4 filling peripheral groove 2a - at a predetermined minimum distance d - preferably, though not necessarily, of 5 to 20 millimetres - from the surface of outer sheet 6.
In addition, the front surface 8b of rigid supporting frame 8 facing inwards of peripheral groove 2a is surface treated electrochemically to alter the surface structure of the material of sections 8 by means of a cold plasma jet (i.e. ionized gas at a temperature below 3000C and preferably, though not necessarily, ranging between 200C and 1000C) to improve adhesion of structural glue 4 to sections 8 of peripheral frame 3.
In the example shown, front surface 8b of rigid supporting frame 8 is surface treated using a cold plasma jet of air and/or silane gas (SiH4) , though gaseous mixtures of other compositions may obviously also be employed.
With reference to Figure 2, facing panel 1 as described above is assembled by first placing outer sheet 6 and inner sheet 7 on opposite sides of spacer frame 5 to form a flat body 2 having a double-glazing type structure and a lateral peripheral groove 2a extending seamlessly about the whole perimeter of flat body 2 and defined laterally by the projecting lateral edges of outer sheet 6 and inner sheet 7; and then pressing outer sheet 6 and inner sheet 7 on spacer frame 5 to keep the whole compact.
With reference to Figures 3 and 4, before fitting peripheral frame 3 to flat body 2, assembly of panel 1 comprises fixing sections 8 of peripheral frame 3, separately from flat body 2 , end to end to one another (Figure 3) to form a rigid supporting frame 8 designed to fit onto, and cover the whole peripheral edge of, sheet
7; and then spraying with a cold plasma jet of preferably, though not necessarily, air and/or silane gas
(SiH4) - i.e. ionized gas at a temperature below 3000C and preferably, though not necessarily, ranging between 2O0C and 1000C - the front surface 8b of rigid supporting frame 8 of peripheral frame 3, which, inside peripheral groove 2a, is eventually positioned facing outer sheet 6 and spacer frame 5, and directly contacting the structural glue 4 injected into peripheral groove 2a (Figure 4) .
With reference to Figure 5, once front surface 8b of peripheral frame 3 is sprayed with the cold plasma jet of preferably, though not necessarily, air and/or silane gas, assembly of panel 1 comprises fitting the treated peripheral frame 3 to the peripheral edge of inner sheet I1 by positioning the whole of peripheral frame 3 facing inner flat sheet 7, on the opposite side to outer sheet 6, and then moving the whole of peripheral frame 3 towards inner sheet 7 in a direction w substantially perpendicular to lying plane P of flat body 2, so that inner annular flange 8a of peripheral frame 3 rests on the exposed face 7a of inner sheet 7, and front surface
8b of peripheral frame 3 is positioned at distance d from the surface of outer sheet 6 inside peripheral groove 2a. With reference to Figure 6, once inner annular flange 8a of peripheral frame 3 is positioned resting on the exposed face 7a of inner sheet 7, assembly of panel 1 comprises injecting structural glue 4 into, and completely filling, peripheral groove 2a of flat body 2. Subsequent drying or polymerization of structural glue 4 inside peripheral groove 2a of flat body 2 provides for simultaneously gluing outer sheet 6, spacer frame 5, inner sheet 7, and peripheral frame 3 firmly and irremovably to one another, so that panel 1 is ready for use.
The above method of assembling facing panel 1 has numerous advantages . When cold plasma sprayed, the front surface 8b of peripheral frame 3 eventually directly contacting structural glue 4 undergoes alterations at molecular level, which enormously improve stable adhesion of structural glue 4 to sections 8 of peripheral frame 3, regardless of the material the sections are made of. More specifically, adhesion of structural glue 4 to the surface of peripheral frame 3 is so improved as to make complete detachment of sheets 6 and 7 from peripheral frame 3 impossible, even in the event of complete breakage of either of sheets 6, 7, thus totally eliminating the need, on peripheral frame 3, for a tab or projecting rib engaging peripheral groove 2a of the central flat body 2.
Cold plasma spraying also eliminates the need for - in fact, renders counterproductive - subsequent "primer" coating, thus drastically reducing pollution associated with the production of facing panels with a double- glazing-type structure, and at the same time improving working conditions by eliminating the handling of toxic chemicals .
Eliminating "primer" coating and the projecting rib of the peripheral frame of the panel obviously greatly simplifies the structure and assembly of peripheral frame 3, and fitting it to flat body 2. Completely assembling peripheral frame 3 before it is fitted to flat body 2 means this stage in the method can also be fully automated, thus greatly reducing the manufacturing cost of building facade facing panels .
Clearly, changes may be made to the method as described and illustrated herein without, however, departing from the scope of the present invention.
For example, in a different embodiment, peripheral frame 3 may comprise a single annular member made of metal, plastic or other rigid material, performing the function of a rigid supporting frame, and sized to fit onto, and cover the whole peripheral edge of, inner sheet 7. In which case, before fitting peripheral frame 3 to flat body 2, assembly of panel 1 comprises spraying with a cold plasma jet (i.e. ionized gas at a temperature below 3000C and preferably, though not necessarily,
ranging between 2O0C and 1000C) the front surface 8b of peripheral frame 3 - or, rather, of the rigid annular member - which, inside peripheral groove 2a, is eventually positioned facing outer sheet 6 and contacting the structural glue 4 injected into peripheral groove 2a (Figure 4) .
