This object is achieved according to the invention by a glass facade component according to claim 1. preferred Embodiments are given in the dependent claims.

The glass façade component according to the invention comprises a planar glass element comprising an inner side and an outer side arranged opposite to the inner side and comprising at least one glass plate. The glass element is intended to be fastened with its edge region to a support structure. This can be done, for example, by screwing the glass façade component to the support structure in a known manner by means of holding devices, or by fastening the glass façade component along the circumference to the support structure by means of a holding profile and a sealant or adhesive.

Furthermore, the glass façade component comprises a protective device which protects against solar radiation and / or other weather-related effects, wherein at least one retaining element is embedded in a passage in the glass element and the protective device is fastened to the retaining element.

According to the invention, it is therefore no longer necessary to provide a special supporting structure or construction for the protective device on the building or on the facade. The protective device is carried by the glass element. In addition, the planning of the facade is simplified and at the same time the construction process is shortened, since no scaffolding for the installation of the protection device must be provided. In addition, the function of the Storenvorrichtung already at the ready manufactured glass facade component and not only after installation on the building.

In particular, the glass element, in plan view of the inner and the outer side, on a substantially rectangular shape. Preferably, the protective device is designed so that the entire rectangular surface of the glass element can be covered with it. This allows easy planning and a correspondingly rational construction of the facade.

A further preferred embodiment relates to a glass facade component, in which a respective holding element is arranged in the corner regions of the glass element. This allows a particularly stable attachment of the protection device on the glass element.

The point mount allows a particularly secure and relatively simple attachment of the protection device on the glass element.

In a further preferred embodiment, the point holder comprises a spacer which extends through the passage and which is covered on the inside and on the outside with a cover plate extending over the edge of the passage. The cover plates seal the passage preferably by means of an annular disc-shaped sealing ring. Optionally, one of the cover plates is integrally formed on the spacer. Such a training of Point holder prevents the ingress of dirt and water into the passage. Next so the cover plates are non-slip fixed to the glass element or the spacer. Preferably, the cover plates are made of metal, more preferably made of aluminum. The spacer is preferably made of plastic, more preferably of a plastic with a low thermal conductivity.

According to the invention, the glass element comprises at least two glass plates arranged congruently one above the other. This makes it possible to obtain a glass element or a glass facade component with good insulation properties.

A further preferred embodiment relates to a glass façade component comprising two adjacent glass plates which, together with a sealing element arranged between the glass plates and enclosing the passage and a spacer strip arranged between the glass plates in the edge region of the glass element, bound an at least preferably approximately evacuated cavity. This can be present as a vacuum, which optimizes the insulation properties.

In particular, the sealing element comprises an annular body which on the one hand serves as a spacer between the glass plates and on the other hand supports the glass plates with respect to the clamping effect of the retaining element.

According to a further preferred embodiment, the protective device comprises a blind device with a blind box, a retractable therein and a blinds Store management. The Storenvorrichtung allows the blinds, which z. B. may be in the form of a lamellar or a Stoffstorens, adjust as needed or to collect in the stork box.

In particular, the blind box is attached to at least two retaining elements. As a result, a very good stability can be achieved, which is particularly important when the Storenvorrichtung or the Storenkasten is exposed to a relatively large stress, such as wind or precipitation.

Another embodiment relates to a glass facade component with a Storenführung comprising two side guides, each leading to a further holding element and are secured thereto. Thus, even when the store is extended, it can be prevented from vibrating, for example as a result of wind or precipitation, and thereby being destroyed.

In particular, the blind device or the blind box is attached to the outside of the glass element. An arrangement of the Storenvorrichtung on the outside of the glass element has particular energy advantages, since in the space between the extended Store (slats or panels) and the facade (building envelope) air circulation by convection arises, which cools the components accordingly and for an approximately constant temperature the facade ensures. Thus, the cooling costs can be reduced in the corresponding building. Continue to protect extended Slats or fabric gates the glass elements from damage by precipitation, such as hail.

In a particularly preferred embodiment, the holding element has a channel leading from the inside to the outside. This channel is used especially when the blind device is arranged on the outside of the glass element.

The inner diameter of the annular body 72 corresponds at least to the diameter of the passage 54 in the glass element 16. The sealing element 70 or the annular body 72 serves - together with the arranged in the edge region of the glass element 16 between the glass plates 18, 18 'and in the Fig.s 1 to 3 shown spacer bar 20 - to limit an at least almost evacuated cavity 74 between the two glass plates 18, 18 '. Further, the annular body 72 serves to support the glass plates 18, 18 'relative to the clamping action generated by the cover plates 59 and the spacer 56. For the purpose of weight reduction, the annular body 72 is preferably formed with a rectangular cross-section and an inner space 76, similar to a box girder or a hollow profile. On the passage 54 facing side of the annular body 72 is a sealing material, preferably a sealing joint 78th arranged. The annular body 72 is preferably made of plastic.

How farther Fig. 5 It can be seen that the glass plate 18 'adjoining the outer side 14 has a greater thickness than the glass plate 18 adjoining the inner side 12. This is due to the fact that the glass plate 18' adjoining the outer side 14 also bears the wind pressure in addition to the stress due to a vacuum is exposed.

In the bores 58, 62 56 O-ring seals 80 may be disposed between the cover plates 59 and the spacer. These O-ring seals 80 prevent ingress of dirt and water into the passage 54.

Fig. 6 also shows an alternative Ausührungsform of the holding member 36 and the point holder 52. In this embodiment, the holding member 36 has a channel 82 which leads from the inner side 12 of the glass element 16 to the outer side 14 of the glass element 16. The channel 82 passes through the cover plates 59 and the spacer 56 therethrough. On the outer side 14 of the glass element 16 arranged cover plate 59, a further mounting bracket 34 'can be seen. This retaining bracket 34 'is attached to the cover plate 59 and carries the blind box 28 and the Storenkastenhaube 48th

In the channel 82, for example, a cable 86 is arranged, which extends from the inner side 12 to the outer side 14 and which serves for electrical control and / or supply of an electric motor of the Storenvorrichtung 24 or the lamella 40 or Storenbahn 42. It is next conceivable, in the channel, a drive element which extends from the inner side 12 to the outer side 14, in particular a drive shaft, to be arranged for the Storenvorrichtung 24. In both cases, this is particularly advantageous if the protective device 26 is arranged on the outer side 14 of the glass element 16.

In Fig. 6 three glass plates 18, 18 ', 18 ", which are spaced apart from one another, are shown, wherein the glass plate 18 adjoining the outside 14 has the greatest thickness for the reasons mentioned above The glass plates 18, 18', 18" are likewise each provided with a ring body 72, 72 'spaced apart.
