Abstract

The large-area glazing with transparent profiles is esp. suitable for installation in part of wholly glass walls which are mainly of opaque glass. Each basic element comprises two glass panes, or panels at a set distance apart, with a spacer frame mounted between them, and connected to them by means of a sealing and adhesive mass. One of the two glass panels, at least, is fitted with lateral length extensions for effective connection to other basic elements in the glass wall. The length extensions may be fitted on different sides on opposite surfaces, so that two glass panels of equal size are mutually displaced sideways, with the spacer frame set between mutually covering areas of panel; or they may be on the same side, with two panels of different sizes.

Description

Large-area profile glazing made of transparent glass The invention relates to large-area profile glazing made of clear glass, preferably for partial installation in intermediate areas made of opaque profile glass All-glass walls.

Large-area all-glass walls where the glass surface does not come through intermediate support elements or rungs is interrupted, but where the entire surface consists entirely of glass, are known. Such large-scale Glazings are produced by using profiled glass, nc-irnlich, usually U-shaped profile glass, which in contrast to flat glass has considerable strength properties, is arranged in such a way that each of the legs forming the U are directed towards one another and one above the other lie, then laterally adjoining, further basic elements with their legs the legs of the first basic elements each engage behind, so that one in itself closed glass surface is created.

The disadvantage of such glass surfaces, however, is that this is necessary for the structure required profile glass is opaque, i.e. such a glass has due to its Structure has such a strong scatter that it is not possible to look through and there is only one permeability for strongly diffusely scattered light.

On the other hand, it is of course known to use transparent glass For certain purposes, however, it is necessary to use it in usual Way to arrange rungs when certain size dimensions are exceeded, i.e. that The basic element is getting smaller and it is not possible to create a continuous all-glass window build up.

In addition, there is also a need for those made of opaque, as spacious all-glass walls made of profiled glass reveal the view Arranging areas or spots to remove the feeling of being locked in will. These transparent areas in a built-up, consisting of profile glass However, all-glass walls must and should be adapted to the building structure of the all-glass wall also manage without support elements and rungs. The difficulty here is, however, that clear profile glass is not or just under can be produced at great expense at great expense.

The invention is therefore based on the object of a large-area profile glazing to create from transparent glass or such large-area glazing areas made of clear glass available as part of opaque All-glass walls can be used.

To solve this problem, the invention is based on large-area profile glazing made of transparent glass and, according to the invention, consists in that per basic element two glass plates maintaining a mutual, predeterminable distance are provided are that a spacer frame is arranged between the glass plates and with the glass plates is connected via a sealant / adhesive and that on at least one glass plate one-piece lateral longitudinal extensions are arranged for effective connection with further basic elements of the all-glass wall.

The invention therefore makes it possible to use large-area glazing either to insert intermediate areas, which are made of transparent profiled glass are, preferably insulating glass, so that it is possible to use a profile glass, to divide the opaque all-glass wall into visible areas through which the view can be seen without Difficulties can get out.

On the other hand, it is also possible to use large-area profile glazing made entirely of transparent glass, with load-bearing Bars can be dispensed with and the large area glazing is still sufficient Has strength.

The invention is only used in opaque Profile glass to build in transparent intermediate areas in existing all-glass walls, then A basic element can also be assumed that consists of two spaced apart held glass plates with an inner frame and only lateral Has longitudinal extensions that correspond to the adjacent areas of the opaque Profile glass basic elements come into operative connection.

If you want large-area glazing made entirely of transparent glass, then preferably U-shaped profiled basic elements are used, which also consist of transparent glass, but where the lateral longitudinal extensions legs are still attached, so that an engaging behind associated legs laterally adjoining basic elements is possible. By known connection techniques you then come to an all-glass wall that is completely transparent.

Only intermediate areas with opaque large-area glazing made of transparent glass, then it is particularly advantageous if a such a viewing zone at the same time combined with ventilation elements whd, so that through these parts to be opened can also be seen through.

Between the two glass plates of each basic element is a Spacer frame basically any material used, but this preferably consists of Metal profile strips.

Optionally, plastic can also be used, it is also possible build the frame from flat longitudinal strips of glass.

The legs attached to the lateral extensions of the glass plates can be made of glass or preferably of metal, it is further preferred here if the legs are part of an angle profile, the other area is flat the longitudinal extensions are attached and, if necessary, with a suitable adhesive is connected to this.

Further refinements of the invention are the subject of the subclaims and laid down in these.

In the following, the structure and mode of operation of Embodiments of the invention explained in detail. Show: Figure 1 shows a first, particularly simply constructed basic element, in conjunction with laterally adjoining further profile elements to form a large all-glass wall Figure 2 shows another embodiment of a basic element with side legs attached to the larger glass plate, preferably for the construction of larger all-glass surfaces made of clear glass and also clarifies the basic structure of a basic element more precisely, FIG. 3 shows the basic element of FIG. 2 in a section along the line 3-3 of Figure 1, Figure 4 shows a section along the line 4-4 of Figure 1 in an enlarged Representation, FIG. 5 shows the same section as FIG. 4 of a preferred embodiment of the spacer frame, Figure 6 shows an enlarged view in section Longitudinal strips that form the spacer frame and are preferably made of metal, FIGS. 7a, 7b show possibilities, as at point A of FIG. 2 in an enlarged manner Representation of the longitudinal strips of the spacing frame are arranged, Figure 8 shows the installation of the embodiment shown in Figure 2 of the transparent base element in an all-glass wall made of U-profile glass and Figure 9 shows the use of the basic element above and below in U-shaped holders of the window frame.

In Figure 1 is a first embodiment of a basic element generally provided with the reference number 1 and consists of a first lower Glass plate 2 and an upper glass plate 3. The dimensions of the glass plates 2 and 3 are essentially the same, but the glass plates are used to build the basic element so shifted against each other that laterally in each case longitudinal extensions 2a and 2b which, as parts of the respective glass plates 2 and 3, are integral with them are and one of the two glass plates 2 and 3 and a frame placed in between 5 formed box profile on both sides and on opposite surfaces, such as shown in Figure 1, protrude. These longitudinal extensions 2a and 2b are used for connection with further, laterally attached basic elements for the construction of a large-area all-glass wall, the further basic elements can be known per se and suitable Wise composite U-profiles made of opaque profile glass, shown in Figure 1 are provided overall with the reference numeral 8, but it is also possible to to attach a basic element 1 made of transparent glass laterally identical basic elements, in this case it is advisable to use the outer edge areas of the longitudinal extensions 2a and 2b to attach legs 7a and 7b extending at right angles thereto, so that there is also a further reaching of adjoining U-profile areas laterally Basic elements is achieved. In Figure 1, the attached legs 7a and 7b are in The dash-dotted line shows the simplest form of a basic element from transparent In any case, glass consists of those that are offset from one another Glass plates 2 and 3, which are transparent, from a spacer frame 5 with which they are connected, are kept at a distance and as a result of the offset lateral longitudinal extensions exhibit.

The connection of this simplest basic element with the adjacent ones Basic elements either of the same type or, in this case preferred, of opaque Profiled glass 8 can be done by filling in suitable sealing material 10 in each case to adjacent surface areas of the basic element 1 and lateral profile glass elements 8, an adhesive or other suitable connection can also be made in the area 11 be, in each of which one leg 12 of the Profilglasele edge to the side Longitudinal extensions 2a and 2b of the basic element 1 abuts. Are not scheduled Leg 7a provided, then the lateral longitudinal extension 2a or 2b of the Basic element already immediately behind the rear edge of the leg 12 of the The next element 8 ends, as indicated in FIG. 1 by the dashed line at 13.

The structure will now be described in detail with the aid of the illustration in FIG of a basic element explained, the basic element 1 shown in FIG differs from the basic element of FIG. 1 than the lateral longitudinal extensions 2a and 2b, as also more clearly taken from the sectional view in FIG can be located on the same side of the surface, but otherwise the structure essentially the same as in Figure 1, particularly as regards the arrangement of the spacer frame 5 concerns. The basic element shown in FIG 1 'therefore exists from a smaller glass plate 2 ', which is lower in the drawing, and an upper one larger glass plate 3 ', here are the relative dimensions of the two glass plates so concerned that the upper plate 3 'the lower plate with the same height dimensions in the lateral direction protrudes in equal parts and in this way the lateral ones Form lancing extensions 2a and 2b.

The diagrammatic representation of FIG. 2 also clearly shows how the basic elements 1 or 1 r are used, they are installed as in the Plane shown diagrammatically, the base element 1 'standing, as in FIG Sectional representation of Figure 9 shown, above and below of the U-shaped Il-aging of the window frame is detected. The sides of the basic element then each butt to laterally attached further (3 round elements either of the same type or to opaque profile glass basic elements 8 according to the representation of Figure 1. The The basic element shown in FIG. 2 also has the longitudinal extensions 2a and 2b attached legs 7a and 7h.

Between the two, the basic element essentially forming and from a transparent glass material consisting of plate 2, 2 'and 3, 3' is the rectangular one Spacer frame 5 arranged.

In the illustrated embodiments, there is this spacer frame from metallic longitudinal strips 4 cut in a corresponding manner Thickness, which, as shown in FIGS. 7a or 7b, is either butted together and are connected, or can be arranged so that they are only along one touch linienförmiqen edge area and in this way formed free Raunl a suitable supplementary element 6 to complete the box profile is introduced.

Of course, the strip strips forming the spacer frame 5 can be used 4 also consist of a plastic material or any other suitable material Material; However, it is b <-preferred that the longitudinal strips 4 themselves as hollow profiles are formed from metal in such a way that an internal cavity is provided is in which a moisture sorbent material such as a dehumidifying salt is arranged; molecular sieves can also be provided in a known manner.

Peim construction can be done so that the longitudinal strips 4 on one of the glass 1) slats, expediently in the exemplary embodiment in FIG the larger glass plate 3 ', initially with the interposition of an adhesive material or a sealing compound, for example also an adhesive tape, and with this Glass plate 3 'are connected, the longitudinal strips running in the transverse direction to the outer edge a predetermined one for the formation of the longitudinal extensions 2a, 2b Keep your distance. The longitudinal strips running in the longitudinal direction of the base element 1, 1 ′ 4 on the inside flush with the glass edge, or a small distance behind be set off inside. The same applies to those on the spacer frame subsequently to be applied, the same size or smaller glass plate 2 ', with only a flush finish or a slight interior depression on all four rare results.

If 5 longitudinal strips 4 are used to build the spacer frame, which, seen by themselves, have a rectangular cross-section, as shown in FIG 4 is shown in more detail, then it is expedient that these form the spacer frame 5 Strip 4 opposite all outer edges of the covering and thus covering Maintain a slight distance between the glass plates, i.e. that on each side of the Spacer frame 5 from the strip 4 as the base part and the slightly protruding Glass edges are formed trough-shaped troughs, like the cross-sectional view of the FIG. 4 shows in which a suitable sealing and / or adhesive compound is filled will.

Depending on the type and structure of the adhesive or sealing material used is the distance from the strips to the outer glass edges and thus to measure the channel-like depression. In this way you achieve an absolute tight connection and a flush finish, so that the entire basic element then the appearance of a parallelepiped with glass surfaces on the largest surfaces of the lateral ones Has elongations.

As FIGS. 4 and 5 show, it is expedient in the construction proceeded so that the immediately adjacent areas of strips and Glass are also provided with an adhesive material 15, for example from a double-sided, strip-shaped material, so that a certain Strength of the basic element 1, 1 'can be achieved; the final structure and the basic element then reaches its final strength through this on all sides Sealing or adhesive material 14 entered into the channel-shaped depression, in this case For example, a thiocol-based sealant may be used will.

For the final structure of the basic element 1 'according to Figure 2 or 3, it is then still necessary to add side legs 7a and 7b that are flush are attached to the protruding Länaserstreckungen 2a, 2b of the upper plate 3 ' and extend in the general direction onto the counter plate 2 '. The attachment the legs 7a, 7b can be made with any adhesive suitable for this purpose, which is able to combine the base plate with the glass material of the base plate 3 'to connect in the joint; the legs consist of a suitable metal, for example an aluminum alloy or the like, then a suitable glass-metal adhesive is expediently used used, metal as the material for the legs is preferred because when Transport reduces the risk of breakage, which is to be feared with glass legs were. In addition, these legs give, in addition to being used for construction about a transparent all-glass wall are required, the basic element 1 'additional Strength and rigidity, especially against twisting.

The height of the legs 7a, 7b is the thickness of the material used Glass plates and, if applicable, the thickness of the adhesive layer used is less, This means that the base elements joined to one another at the side are flush and form a uniform Form front without protruding part elements.

The juxtaposition and assembly of the individual basic elements for the construction of larger glass wall areas then takes place as shown in Figure 1 or 8, i.e. a transparent all-glass wall is formed, for example, by a sequence alternately inverted basic elements 1 ', which are located with their associated legs reach behind in the Way that the leg of the to a base element laterally attached, further basic element with its free. Transverse edge on the inner surface of the respectively assigned glass plate rests and in this way engages behind the leg attached directly to this glass plate. The other one The basic elements can then be assembled to form an all-glass wall in such a way that this each leg engaging behind each other immediately by a correspondingly Applied suitable glue with the larger glass plate of the other Basic element can be connected, the gaps can be either be kept so close -or. with other places, the outstanding longitudinal expansions can be so short - that the legs lie close together in flat contact reach behind and on their transverse surfaces with one another by means of suitable sealing agents are connected over a large area, but it is also possible to keep larger distances and in this a suitable insulating material, such as Styrofoam, Poresta or another Ilarz foam or some other air-conditioned t1ateria]. enter and then each the spaces left open, i.e. the spaces between the outer ones adjoining edges each of the glass plate. 2 and the glass plate 3 through the application of a sealing compound or other suitable sealing material To seal, an adhesive based on silicone is particularly suitable here. This has already been discussed in a similar manner in connection with FIG. The lower areas of the composite all-glass walls consisting of basic elements are, as already mentioned earlier and shown in Figure 9, in the U-shaped anyway Profilhalterunqen 16 held the window frame, so that there is a further seal unnecessary.

As can be seen, in this way one achieves a pleasing appearance an all-glass wall assembled from several basic elements, as in Figure 8 shown, if desired, also the entire lower base part 17 of the respective Legs and the protruding longitudinal extensions of the respective glass plate formed Cavity into which the leg of the other base element then protrudes, with a suitable flat material is designed, which has an attractive structure and arc can be such that the different stratification in this area if if you look at the all-glass walls, it is covered. This stratification comes from that each associated leg of the adjoining base element and possibly inserted between insulating pieces made of rigid foam and the like.

According to an advantageous embodiment, which is shown in the figure 5 are made of metal or other suitable material existing strips 4 'for the construction of the spacer frame 5 have a cross-sectional shape on, the longitudinal edges associated with the glass walls, as seen in FIG can be set down to a predetermined height, so that a free lowered Cavity 18 is formed between the strips and the glass plates. The Stripes are then placed between the glass plates 2 and 3 during the construction of the spacer frame The upper outer surface 19 of the strip is shown to be flush with the outer edge The glass plate closes off so that not one over the entire width of the gap the glass plates running indentation is created, which is filled with i) sealing compound must be, but the f) sealing compound then only needs to be in the resulting Cavities 18 to be entered on both sides to ensure safe To achieve connection of the spacer frame and the associated glass plates 2 and 3. This saves a considerable amount of the not cheap sealing / adhesive material and at the same time possibly achieves a more pleasing appearance insofar as the metal surface that remains free is visible. This, the cavities 18 between The sealing compound 20 filling the strip and the glass plates can also be used in substantially Thinner layers can be added between the areas where the not deposited Edge areas of the strips butt directly against the glass and then form the already mentioned area 15, but optionally a double-sided adhesive, suitable tape can be arranged, as already mentioned above.

In a built-up embodiment, the height of the spacing was between the two glass plates 35 mm and is therefore made of the usual profile glass walls adapted to opaque glass; the thickness of the strips 4, 4 'can be trough-shaped lowered construction of the spacer frame be about 4 mm - this is at the same time the thickness that zvfecksamigerweise for direct contact between strips and Glass wall is maintained -; with the last discussed construction of the spacer frame 5 therefore results in a total height of the strips 4 'of about 8 mm, thereby at same width of contact of strip 4 'and glass of 4 mm for sufficient Depth of also about 4 mm for the introduction of the adhesive 20 into the offset Area to worry.

The absolute size of the basic element depends on the respective Requirements; the height can be up to 3 m and more amount to the Width can be dimensioned so that sufficient strength even with very strong ones external forces acting on the all-glass edge, for example higher during storms the speed, be maintained.

It has already been mentioned earlier that the strips 4, 4 'for the spacer frame 5 are designed as a hollow profile, so that a Dehumidifier salt can be arranged. So that this dehumidifier salt is on the hollow formed by the spacer frame and the covering glass plates 2 and 3 Space can have an impact on drilling holes in the profile of the strip at given intervals be provided; according to an advantageous embodiment shown in FIG is, however, the profile can also be formed so that it is in its inner location an overlap 21, in the area of which the overlapping material parts do not lie completely next to each other or only do this at intervals, for example if there a corrugation is provided, so that also here the Fntfeuchtersalz with the The hollow space formed and the air enclosed there in direct connection stands.

It goes without saying that as glass for the glass plates 2 and 3 and optionally any transparent glass can also be used for the legs 7a, 7b can, for example, safety glass in the form of laminated glass, also tinted in color Glasses or sun protection glasses in various thicknesses, with a suitable one Material vapor-coated glass, in particular gold-vaporized glass.

If, according to the illustration in FIG. 8, the transparent one is made one or more basic elements formed large-area profile glazing in all-glass walls built in from opaque profile glass, then it is not necessary that the Basic element made of transparent glass also has the same thickness as the profile glass, there in the top and bottom running U-Profiltrciger 16 of the window frame filler panels or shims can be used in the area of the basic elements, so that there is also a tight fit.

Finally, there is another advantageous exemplary embodiment still in the fact that the laterally attached legs 7, 7a to form the U-profile not necessarily to be set in the joint with the lower, larger glass plate need, for example, the right side of the cross-sectional view of the Figure 3 shows; the legs can also have an angle profile, one and usually shorter legs 22 of the angle profile flat on the longitudinal extensions 2a placed on the larger plate and using a suitable adhesive or in is otherwise connected to this.

This is shown on the left-hand side of FIG. One attains on In this way, a considerably greater strength in terms of the connection of leg 7a with the larger plate 3 ', on the other hand in this case needs the lower base part of the longitudinal extensions of the glass plate 2 and the legs formed cavity not, as explained above, with a suitable flat Material can be interpreted, as this task is then carried out by the flat-lying leg of the angle profile is adopted.
