Description

The invention relates to a glass facade with glass panels according to the preamble of claim 1, wherein the glass panels are held by a carrier on a building and form a building exterior wall or protective outside of a building exterior wall, the glass panels vertical glass panel rows seen in front view overlap each other in the manner of roof tiles or shingles, but do not touch each other directly.

Such on the building exterior wall patch glass facades serve on the one hand a thermal insulation, on the other hand also to protect against weathering and other mechanical damage. Thus, the heating costs can be reduced, but also the maintenance costs, the building exterior wall only rarely, if ever repainted or even new plastered.

The DE 10307866 A1 discloses a generic glass facade of frameless laid and scaly overlapping glass panels, disk holders are provided with support surfaces, on each of which rests the lower edge of an upper glass panel. The disc holders have projecting and projecting from the building substructure support rods which pass through holes in the upper corners of the lower glass panels, the lower glass panel is secured against displacement in the axial direction of the rod, and at the from the building substructure facing away from carrying parts are releasably secured, which have the support surface for the lower edge of the upper glass sheet.

The EP 1136632 B1 discloses a generic glass facade made of glass panels, which are successively arranged in a scale overlapping from top to bottom along the facade. Furthermore, a double and a quadruple holder for the storage of two or four glass panels are disclosed.

Disadvantage of the aforementioned generic glass facades of glass panels is that only vertically stacked glass panels overlap and protect from rain, but horizontally juxtaposed glass panels a certain Distance from each other must take, since the support structure made of steel or aluminum are exposed to thermal expansions and thus the glass panels are damaged when they are set without impact and shock.

The DE 203 04 988 U1 shows a glass component, which is suitable in combination with other glass components to cover a roof or a facade surface. The glass components used each consist of an upper and a lower disc, with an intermediate space between them. The upper pane of each glass component has a wing-like overlapping area on two sides, which makes it possible to overlap an underlying glass component in the horizontal direction and another element in the vertical direction.

However, this means that it is not possible to overlap four adjoining glass components, but in this case always one element - starting from a corner of the facade - must cover two further elements, which in turn each overlap two further glass elements with their lateral overlapping wings.

The glass components are also very heavy due to the sandwich structure and require a stable and therefore costly mounting and anchoring to the building.

Another disadvantage is that the linear bearing, the load (wind pressure, snow, etc.) over the entire edge, i. over the entire length is delivered to the underlying element.

The object of the present invention is therefore to further develop a generic glass façade of glass panels in such a way that the impermeability to weathering is substantially improved without the glass façade becoming substantially more expensive.

To achieve the object serve the features of claim 1. Further developments are the subject of the dependent claims.

It is essential that the overshoot, i. Overlapping of the glass panels takes place in both the horizontal and vertical direction, wherein the edges in the corner of four adjacent glass panels overlap each other and these edges are held in the corner of the glass panels in a single carrier. The advantage is that there are no more vertical joints and thus the rain impermeability is substantially improved, as well as the protection against dirt particles and mechanical damage of possibly located underneath the building exterior wall or in the building objects (such as vehicles in a garage). In addition, this construction is very cost-effective, since four breakpoints or support must be present per glass panel anyway, which then need only vary in the present invention at a distance to the building exterior wall or to a building support element.

Here, the scaling of the horizontal rows of glass sheets, as well as those of the vertical rows of glass sheets, can be made oblique at a defined constant angle of e.g. 5 ° (from left to right sloping or ascending), or the horizontal glass panel rows can be arranged without skew on two, three or four different planes parallel spaced from each other or to the building exterior wall or to an imaginary vertical.

Irrespective of whether the glass sheets run obliquely or parallel to the outer wall of the building or to the imaginary vertical, it is preferred if the scaling or overlapping takes place in such a way that the vertical and horizontal glass sheets alternately overlap or interlock. It is therefore at two mutually adjacent vertical glass panel rows first a first glass sheet of the first vertical glass sheet row over a first glass sheet of the second vertical glass sheet row. Below this first glass panel of the second vertical row of glass panels lies the second glass panel of the first vertical row of glass panels. Below this second glass panel of the first vertical row of glass panels is then the second glass panel of the second vertical row of glass panels. Of course, the analog reverse arrangement case may be provided.

The glass panels of the horizontal rows of glass panels can increase from left to right or from right to left. However, the glass panels of the vertical rows of glass panels always rise from top to bottom - or in other words, the glass panels of the vertical rows of glass panels always fall from bottom to top, reliably transporting rainwater to the ground rather than to the building's exterior wall or building Interior is derived.

The rise and fall of the glass panels of the vertical and horizontal rows of glass sheets is achieved by carriers of different depths, these supports preferably being depth-adjustable, i. are formed in the direction of the building exterior wall or the building interior.

The distance in the depth between two adjacent glass sheets is about 5 to 15 mm, typically 10 mm. The overlap area in the height and width between two adjacent glass panels is about 0 to 60 mm, typically 20 mm.

Preferably, a single support for each corner of four different glass panels adjacent to each other, wherein all four corners of each glass sheet are held in a carrier. However, louder individual carriers can be provided for each corner of the glass panels.

In the following the invention will be explained in more detail by way of example with reference to drawings, from which emerge further features and advantages of the invention.

• Figur 1: Seitenansicht im Querschnitt durch die Fassadenmitte im Bereich der Träger;
• Figur 2: Draufsicht auf die Fassade nach Figur 1 im Querschnitt im Bereich der untersten Träger;
• Figur 3: Frontansicht auf die Fassade nach Figuren 1 und 2;
• Figur 4: Draufsicht auf die Fassade nach Figur 1 im Querschnitt im Bereich des mittleren Vierfach-Trägers ohne äußere Träger.

It shows

• FIG. 1 : Side view in cross section through the facade center in the area of the carrier;
• FIG. 2 : Top view on the facade behind FIG. 1 in cross-section in the area of the lowest support;
• FIG. 3 : Front view on the facade after FIGS. 1 and 2 ;
• FIG. 4 : Top view on the facade behind FIG. 1 in cross-section in the region of the middle quadruple support without outer support.

The figures show a glass facade 1 with four glass panels 2-5, which are connected by means of carriers 6-14 with a building exterior wall 15. Of course, the glass facade 1 may also form the building exterior wall itself and be fixed on another building support structure (not shown) via supports 6-14.

The four glass panels 2-5 of the glass facade 1 are arranged such that they occupy a depth distance 21, 23 of about 10 mm to each other and two in the height direction 19 extending, mutually adjacent, vertical glass panel rows 16 and two in the width direction 20 extending, to each other form adjacent, horizontal glass panel rows 17, which according to the invention in the direction of depth 18 overlap or overlap both vertically and horizontally. Thus, each vertical, as well as horizontally adjacent glass panels 2-5 are overlapped or overlapped by an overlap 22, 24 of about 20 mm, but they do not touch each other directly, but the depth distance 21, 23 of about 10 mm to each other comply.

In FIG. 4 it can be seen in the region of the middle holder 7 that the coverage of the vertical glass panel rows 16 has priority over the coverage of the horizontal glass panel rows 17, so that the upper left glass panel 2 is on top, further down in the depth direction 18 then the right upper glass sheet 4 follows, followed by the lower left glass sheet 3, followed by the lower right glass sheet 5, which each hold a depth distance 23 of about 10 mm in the depth direction 18 and do not touch each other directly. Of course, the order of the glass panels can also be analogously reversed (seen in the depth direction 18): 4, 2, 5, 3, instead of 2, 4, 3, 5.

Of course, in another embodiment of the invention, it is also possible that the overlap of the horizontal glass sheet rows 17 takes precedence over the overlap of the vertical glass sheet rows 16, then the order of the glass sheets would be (seen in the depth direction 18): 2, 3 , 4, 5 or, conversely, conversely 4, 5, 2, 3.

The stratification or overlap is therefore almost arbitrary, but the two vertically upper glass sheets 2, 4 are always seen in the direction of depth 18 (ie in the direction away from the building) the vertically lower glass sheets 3, 5, so that rainwater not behind the glass sheets 2- 5, but before it runs to the bottom.

It goes without saying that the number of glass sheets 2-5 can also be 6, 8, 10, 12 or more, but the previously explained principle of layering or overlapping is always maintained or even can vary within a glass facade 1 ,

The Figures 1-3 It can be seen that the outer edges of individual glass sheets 2-5 are held by single beams 9, 11 and 12, 14, the edges of two adjacent glass sheets 2-5 via horizontal double beams 6, 8 and depth double Carrier 10, 13, and the edges of four adjacent glass sheets 2-5 on the quadruple support 7th

All carriers 6-14 are adjustable in the depth direction 18 in that they are formed by different angles, which are connected to each other via fasteners 26 which engage in slots 25 in one of the opposite angles of the carrier 6-14.
