Definitions

  • such panels consist of a metal support frame, into which is mounted a glass sheet or pane and, more precisely, a double-sheet pane with an intermediate insulating cham­ber. Nevertheless, when using such panels, at least part of the frame profile shows up along the contour of the pane, thereby forming an inte­grating element of the overall aesthetic appearance of the building wall.
  • the metal frame supporting this double-sheet pane has a two-stepped profile, the contour of the inside sheet being glued onto the innermost step and the contour of the outside sheet being glued onto the outermost step; the outside sheet is moreover dimensioned so that the support frame appears fully masked from the external side.
  • the glueing is carried out by means of a silicone adhesive.
  • the metal support frame is formed starting from a section having an outwardly facing channel groove. Into this groove there is housed, and retained by mechanical means, a glass strip, onto which is glued the edge of the single- or double-sheet pane by means of a silicone adhesive.
  • the object of the present invention is a process for the cons­truction of glass wall panels, fundamentally based on the glueing techni­que, which is apt to simplify and speed up said construction, which can be used with automatic systems on a vast scale and, above all, which pro­vides for the highest guarantees of length and reliability throughout lifetime.
  • said superfi­cial covering layer is formed by melting of metal obtained by plasma spray.
  • said superficial covering layer is formed of a material having a chemical af­finity with the silicone adhesive, and particularly by melting of a vi­treous enamel layer.
  • Figure 2 shows (always on a very enlarged scale) a glass panel length obtained according to the fundamental characteristic of the pre­sent invention: the metal section 2 is actually provided - over at least its front adhesion surface - with a covering layer consisting of a vitre­ous enamel or of a melted metal obtained by plasma spray.
  • the technology of applying a surface covering layer of vitreous enamel has been known for a long time and it consists in remelting a frit over the metal surface. If the metal is iron, the remelting is done at a relatively high temperature, for instance up to 1000°C; whereas, if an aluminium section is involved, care will be taken to use a low-melting frit, whereby the remelting can be carried out at about 500°C. Since, as said, these technologies are known, it is not deemed necessary to descri­be them in detail.
  • said enamel covering layer has always been applied merely as a surface finishing and/or protection element for the underlying metallic material (especially in sanitary apparatuses), but it has never been used - according to the fundamental teaching of the present invention - to produce a surface apt to guarantee a reliable adhesion for a silicone layer.
  • Figure 2 clearly shows how the enamel layer P is apt to fill the cited microcavities and ends up by leveling the surface of the metal sec­tion and making it homogeneous.
  • the resulting surface P′ contacting the silicone is therefore smooth and uniform, and is apt to guarantee a per­fect and continuous adhesion of the silicone layer, comparable to the ad­hesion on the opposite glass surface of the pane L.
  • the same effect of the enamel layer can be obtained - according to the invention - by applying a covering formed of a metallic layer by means of the plasma-spray technique; this consists in the continuous melting of metallic powders through a voltaic arc immersed into an envi­ronment controlled by inert gas. According to this technique, the melted microparticles are cast onto the surface of the support metal section, onto which they thus settle by melting. This melted metal layer can reach a thickness of a few millimeter tens. Since also this technology is known - though from more recent times - it is not deemed necessary to describe it in further detail.
  • the technique of the present invention is used for mounting a glass panel directly onto its support structure.
  • the structure con­sists of a base metal frame 1 - for instance an iron or aluminium frame - which is shaped and sized according to the construction requirements of the glass wall.
  • a base metal frame 1 for instance an iron or aluminium frame - which is shaped and sized according to the construction requirements of the glass wall.
  • the fixing is done by known means, for instance by tripping engagement or by screws or the like.
  • a gasket 5 - prefe­rably an extruded reinforced silicone gasket - onto which is rested the pane 3. Since said gasket projects above the level of the section 2, bet­ween this latter and the inner surface of the pane 3 there is a free spa­ce into which is injected the silicone adhesive S by means of a spray nozzle U.
  • an additional advantage of the process according to the present invention lies in the fact that the spray nozzle has a free access into the space between the pane 3 and the section 2, whereby this space can be filled with silicone under visual control and in ideal conditions to guarantee a perfect filling.
  • Said section comprises an essentially L-shaped portion 6a-6b, to which there is associated an essentially T-shaped portion 6c-6d: the portion 6a is used for a mechanical anchorage onto the frame 1, for instance by means of a screw 7; the portion 6b is used to support, in lateral projection, the T-shaped portion of the section 6; the portion 6c is used to support, in projection towards the front of the glass wall, the top transversal portion 6d of the T; and this portion 6d is used for supporting directly the pane 4, which is fixed thereon by glueing (see figure 6).
  • the shaped section 6 is provided - at least onto the surface of its portion 6d supporting the pane 4 - with an enamel or melted metal covering layer, according to the fundamental characteristic of the present invention.
  • the configuration is such that, between the facing surfaces of the portion 6d and of the pane 4 there is a free space - similar to the previously described space between the section 2 and the pane 3 - into which it is possible to inject the silicone adhesive layer S, under per­fect visual control, by means of a spray nozzle U.
  • the silicone adhesive is applied to an extent sufficient to fill the whole space between the portion 6d of the section 6 and the pane 4, up to pressing against the silicone gasket 8 which joins the two panes 3 and 4 and which defines the intermediate insulating chamber. This evi­dently guarantees a supplementary anchorage.
  • FIG. 7 to 10 shows a different method to carry out the process of the invention, according to which the glass panel is not applied directly onto its support structure, but onto a rim frame which is then mechanically fixed onto said support structure.
  • This arrangement has the double advantage of facilitating transport of the glass panels, separately from their respective support structures, and of allowing fast replacement of an eventually damaged glass panel.
  • the rim frame 9 has an overall L-shaped section, wherein the base of the L defines a first adhesion surface 9′ and the top of the L has a widened portion which defines a second adhe­sion surface 9 ⁇ . Both surfaces 9′ and 9 ⁇ are treated with the process of the invention and are thus provided with a vitreous enamel or a melted metal adhesive covering layer.
  • the rim frame 9 is also provided with a seat into which is fit­ted a gasket 10, preferably an extruded reinforced silicone gasket, onto which is rested a double-sheet pane 3, 4, fully similar to that shown in figures 3 to 6.
  • a gasket 10 preferably an extruded reinforced silicone gasket
  • the silicone adhesive layer S is injected with a nozzle U at a pressure suf­ficient for the adhesive to fill the whole space between the frame 9 and the facing surfaces of the panes 3, 4, and of the gasket 8 interposed therebetween (see figure 8).
  • the glass panel can be mounted onto a support structure 11 by suit­able mechanical means, for instance by a tightening screw or bolt 12, as shown in figures 9 and 10.
  • Figure 11 shows part of a glass wall comprising, on one hand, a main support structure for the glass panels, consisting of sections 11, 11′, and on the other hand, a plurality of rim frames, consisting of sec­tions 12, onto each of which is fixed by glueing a pane 13.
  • the pane 13 is a single-sheet pane, glued onto the side 12a of the rim frame by means of a silicone adhesive layer 14 and with the in­terposition of a spacing gasket 15.
  • screw dowels 16 preferably comprise a socket screwing head 16a, while the opposite end 16b thereof forms an anchor pin emerging into a space delimited by two ribs 12c formed in the rim frame.
  • the rim frame 12 is mounted on the support structure (as indica­ted in continuous lines on the right of fig. 11, and in dashed lines on the left of the same figure) by positioning its side 12b next to the side 11b of the section 11 of said support structure, which is in turn perpen­dicular to the pane.
  • Each dowel 16 is screwed, by means of a suitable spanner 17, until its end or pin 16b engages into a cavity of anchorage formed between two ribs 11c of the side 11b of the section 11.
  • the spanner 17 is operated by acting from the inside of the glass wall into the free space between two posts of the section 11 defining the window span.
  • a protective sealing gasket 18 is applied onto the side 12b of the section 12.
  • Another gasket 19 is applied onto the post 11 of the support structure.
  • the heretofore described arrangement can also be inverted when having to mount the glass panel in correspondence of an area of the glass wall provided with a bulkhead P, having an even partial closing function, for instance the function of a breast. In this case, it would in fact be impossible to operate the spanner 17 from the inside.
  • the threaded hole into which screws the dowel 16 is formed on the side 11b of the section 11′ of the structure supporting the glass wall - as shown on the right of fig. 11 in correspondence of the cavity formed between the two ribs 11c.
  • the do­wel 16 can thus be screwed from the outside of the glass wall, as indi­cated by the position of the spanner 17′.
  • the screwing action allows the tip 16c of the dowel 16 to engage into the cavity formed between the ribs 12c of the section 12, thereby firmly fixing the rim frame onto the sup­port structure of the glass wall.
  • a double-sheet pane 20, 21, is adopted - of the special type already described with reference to the embodiment of figures 3 to 6 - wherein the contour of the outside pane 20 has larger dimensions than that of the inside pane 21.
  • Such a double pane requires the use of a rim frame 22 formed of substantially Z-shaped sec­tions: each section has in fact two sides 22a, 22b, parallel to the glass wall, onto which are glued the panes 20 and 21 respectively, and one side 22c perpendicular to the glass wall, which joins the sides 22a, 22b, and which is used to anchor the rim frame onto the support structure by means of the dowels 16, as previously seen.
  • Figure 12 shows, on the left, the anchorage of the rim frame 22 onto a section 23 of the support structure, being in this case the sec­tion of a window or door frame in a closed position.
  • This section has in turn one side 23a perpendicular to the glass wall and thus parallel to the side 22c.
  • the dowels 16 are screwed into suitable threaded holes pro­vided on said side 23a of the section 23, and their head 16b engages into the groove-shaped cavity 22d provided on the side 22c.
  • the constructive variants according to figu­res 7 to 10, and particularly figures 11 and 12, allow to obtain the fol­lowing additional advantages in respect of known technology: - at the initial stage, the mounting of the glass wall merely involves the construction of the support structure comprising the sections (11, 11′) which, being at this stage free from other structures, are light and can easily and rapidly be fixed onto the building skeleton; - the mounting of the single- or double-sheet pane is done in the facto­ry, onto a light rim frame which is easy to handle, and thus in the best working conditions; - this easy handling allows to transport and mount the glass panels onto their support structure without any particular difficulties; - this easy mounting allows furthermore a fast replacement of any damaged panels.
