The invention consists of a glass wall which is suitable for use as a window within buildings or wholly or partly as an external skin.

Glass walls have been a part of construction for many years. Architectural tastes play a role here, but above all technical functions. This includes, above all, the entry of light into buildings, the free view through partition walls in buildings or at least a high level of light permeability within buildings, as well as a view to the outside.

Such arrangements, often referred to as functional glazing, are currently gaining additional importance in the generation of passive solar energy and/or in noise protection.

Well-known examples of the use of glass walls can be found in simple designs in greenhouses. Similar arrangements of glass walls, but mainly insulated, are becoming increasingly important as winter garden-like parts of residential buildings and office buildings.

The redesign of entire city districts often includes glass structures as shopping arcades, shops and offices in buildings with predominantly commercial use.

The glass walls of such buildings usually consist of supporting structures into which single panes or double glazing are inserted, which are manufactured according to the generally known methods using spacers and an edge sealing system that is as vapor-tight as possible. Flat and curved glazing is used.

There are government minimum requirements for this, e.g. in the Thermal Insulation Ordinance of February 24, 1982.

A disadvantage of such a glass wall is often the inhomogeneous structure of the wall. Furthermore, special profile constructions are required! which must comply with the installation regulations for the glazing of multi-pane insulating glass from the manufacturers in the currently valid versions, so that the glass parts in the wall are not damaged by the transfer of forces, especially in the case of twisting due to external loads such as wind pressure, snow loads or locally high temperature differences.

For this reason, profile-free glazing systems have been developed in the USA, in which panes are glued to the supporting structures over a large area and thus incorporated into the static bond, similar to what happens with automotive glazing (structural glazing). However, the usual insulating glass is not ideal for this due to its multi-layered structure. For example, the gas volume hermetically enclosed in the pane wheel causes deformation of the panes due to pressure differences (inside/outside) and stresses on the outer bond when there are fluctuations in air pressure and temperature. This phenomenon, known as the insulating glass effect, also limits the depth of the air gap, which is actually desirable for insulation. The glass folds that are common in this type of gasification tend to be more or less prone to water ingress, exacerbated by differences in expansion.

This results in consequential damage, both for the insulating glass and for the supporting structure. In all known cases, the supporting structures, regardless of the material they are made of, are exposed to moisture attack, as only the inside of the insulating glazing remains free of condensation due to the drying agents stored in it, while leaky glass folds endanger the edge bond of the panes and thus the service life of the insulation.

The invention is based on the object of eliminating the above-mentioned disadvantages and of creating a uniform powder-shelled glass wall which is suitable for combining static, sound and heat insulating properties in a condensate-preventing arrangement.

This goal is achieved by including the supporting structures as completely as possible in the zone of condensate-free air or gas volumes.

The glass wall is constructed from a supporting structure of hollow profiles, onto which glass panes are preferably glued on the inner and outer surfaces. In this arrangement, the inner and outer surfaces are almost completely covered by glass panes, apart from small assembly or expansion joints, which are sealed with water vapor-barrier putties or adhesives.

The hollow profiles of the supporting structure serve as supply and discharge lines for conditioned air or conditioned gases between the panes, i.e. gaseous media whose dew point and/or temperature are optimally adapted to the desired target. Conditioning is carried out by suitable units that are connected to the supply and discharge lines in the hollow profiles of the supporting structure.

The term "conditioning" was chosen because the glass wall according to the invention with its enlarged gaps between the panes also allows the use of gas compositions that were previously not common, for example gases that increase the greenhouse effect desired here. A preferred embodiment of the invention is characterized in claims and 3.

Drawing 1 shows a perspective view of a double-skin glass wall, which is suitable for winter gardens or projecting building sections, for example.

A supporting structure made up of the cross beams (3) and the longitudinal beams (4) and (5) lying between flat or curved glass panes (1) and (2) forms a unit that is permanently bonded to the contact surfaces of the panes. Part of the profiles serves as a supply or exhaust air (gas) line for supplying the gaps with conditioned air (gas). In the drawing, the ascending profiles (4) are assumed to be supply lines and the profiles (5) as return lines, although other combinations may also be advantageous in certain cases. The profiles (4) and (5) should be supplied via terminal supply lines not shown here. In this way, additional cooled air (gas) can be fed into the upper connections, which counteracts heat build-up in the event of strong solar radiation.

In the profiles (4) and (5) channels (6) are indicated, from

with openings leading into the spaces between the panes.

The expansion joints (7) are elastically sealed to be water-repellent.

A range of special profiles available on the market are available to choose from, particularly those with thermal insulation between the outside and inside, which is not referred to in the drawing.

In this example, GiAS is assumed to be tempered flat glass on the outside and laminated safety glass on the inside, but other types of glass such as ornamental glass, filter glass or even wired glass may be more appropriate in individual cases. Decorative bars can be glued on and/or inserted if desired.
Drawing 2 shows a cross-section of an all-glass corner as an example.

The glass wall constructed according to the invention is also particularly cost-effective to manufacture due to its simple arrangement and easy assembly. The larger gaps possible compared to standard Taolier glazing allow for high insulation values.

Combinations of different glass thicknesses easily lead to sound insulation, especially in conjunction with suitable acoustic and thermally insulating profiles. The mechanically favorable large-area bonding allows in many cases light load-bearing structures, especially since the supply and discharge channels for conditioned air or gases allow complete pressure equalization in the event of air pressure and/or temperature fluctuations.
