Description

The invention is in the field of cladding for roof or facade construction with the help of glass components.

Roof or facade cladding based on glass components are used in modern architecture in many different applications to use daylight to illuminate spaces in buildings as much as possible. Furthermore, the use of large-scale roof / facade cladding of glass components allows a comprehensive view of people in rooms to the outside. It is known to use large-scale glass components for the covering of glass surfaces. In this case, glass components, which are arranged adjacent to each other in the direction of the inclination of a roof / facade surface, partially overlapping, so that the overlap covers transverse to the direction of inclination of the roof / facade surface extending horizontal joints. The overlap is intended to ensure that running on the roof surfaces water does not get between the glass components, but flows directly from the overlapping edge of an upper glass component directly to the surfaces of each adjacent glass components in the direction of inclination. However, such an overlapping arrangement of the glass components along the direction of the roof pitch has the result that adjacent glass components in the direction transverse to the roof pitch laterally abut each other so that between adjacent edges of the glass components in the direction of the roof pitch results in a non-overlapped joint. To seal this joint area against the ingress of water either non-transparent sealing elements are used, for example, elastic sealing lips with a cover strip, or permanently elastic sealing materials that are either directly exposed to the running water or covered again with the help of strips.

The document DE 198 59 888 C2 relates to an arrangement for fixing insulating glass panes with a holding element, an insulating glass pane and a supporting structure. The insulating glass pane has an upper and a lower disk component, wherein opposite edge portions of the components are formed projecting.

From the document DE 83 03 123 U1 is a laminated glass with a supernatant known. Projecting edge portions of the disc are arranged on opposite side edges.

The document DE 297 12 253 U1 discloses a sealing member for sealing glass sheets arranged on a support structure according to a principle of Verschindelungsprinzip. The sealing element is arranged in the region of side surfaces of the glass panes and has a drip edge profile.

The document DE 644 761 A discloses a glazing having a plurality of glass sheets stacked on the width and height edges. The corners of glass plates abutting one another are bevelled.

Starting from the document DE 198 59 888 C2 It is an object of the invention to provide an improved glass component and a glass panel with an arrangement of several glass components for roof or facade construction, which facilitate the sealing of glass roofs or facades to water, with the greatest possible glass transparency is to be maintained.

This object is achieved by a glass component according to the independent claim 1 and a glass panel for a roof or a facade according to the independent claim 8.

In the glass component according to the invention for the roof or façade construction, an upper disk component is arranged above a lower disk component, wherein on the upper disk component along two adjacent side edges in each case an overhanging edge portion is formed, which projects beyond the lower disk component, and the protruding edge portions in a respective corner region, which is adjacent to a side edge without protruding edge portion, are chamfered. The so designed glass component allows the construction of a roof or a cladding of glass, in the non-overlapping joints between side edges of adjacent glass components, d. H. Joints that are to close the space below the roof or behind the facade to the outside environment and are not overlapped by glass, are avoided. When using the glass component according to the invention thus significantly reduces or eliminates the effort to seal not glass overlapping joints. The entire roof / façade surface can be formed in this way with joints of the same joint quality.

By means of an arrangement of a plurality of glass components embodied in this manner, a glass cladding for a roof or a façade can be provided, wherein a common corner region of one of the plurality of glass components formed by the protruding edge portions forms a joint between adjacent edges in the chamfered corner regions of two others overlaps the multiple glass components. The beveled corner areas therefore allow on the one hand the contiguous arrangement of the several glass components and on the other hand, the glass joint overlap.

The glass component can be designed according to an embodiment of the invention preferably so that in the respective corner region a non-beveled portion of the protruding edge portion is formed. In this way, a complete covering of a joint formed under the projecting edge portion between two adjacent in the same plane glass components when using the glass component is ensured together with other glass components. The formation of the joint is usually necessary in order to prevent adjacent side edges of glass components abut each other in roof or facade construction, which would lead to damage of the glass components. In addition, a gap thus formed allows movement of the glass components. The intended joint can be at least partially filled with the aid of a sealing material.

In a preferred embodiment of the invention can be provided that a lower surface of the upper disc member and an upper surface of the lower disc member are adhesively bonded to each other by means of an adhesive surface. As a result, a so-called single-disc design of the glass component is created, which can be produced with little effort. The adhesive may be, for example, an adhesive film.

Suitably, an embodiment of the invention provide that along a peripheral edge a sealing profile for sealing a gap formed between the upper and the lower disc member is arranged, so that an insulating glass component is formed. However, such an insulating glass component, the production of which can be more expensive compared to the single-disc design, however, ensures a thermal insulation of the space on the inside of the glass component from the external environment. The sealing profile preferably seals the interspace so that the interspace can be provided with a suitable gas filling in order to further improve the insulating properties.

An expedient development of the invention may provide that on the glass component, a receiving member for receiving a portion of a support element for a point-like support is provided. A punctiform support of the glass component ensures that the largest possible part of the glass component is available for the desired daylight incidence or the desired view to the outside.

An expedient development of the invention provides that the receiving member is mounted in an opening in the lower disc member, wherein the opening is sealed fluid-tight. In this way, the mounted receiving member remains independent of external weather conditions, since it is shielded to the outside by the upper disc member.

A simple mounting of the support device for the glass component is achieved in a preferred development of the invention in that the receiving part has an internally threaded portion for screwing in the portion of the support member.

The glass cladding for roof or façade construction with an arrangement of several glass components can preferably be further developed in that the one glass component and the other two glass components each have a quadrangular basic shape and a direction of inclination of the arrangement with the plurality of glass components in the direction of a diagonal of one Glass element is formed, which extends from a corner point in which the side edges of a glass component without protruding edge portion of each other, to an opposite corner point, in which the side edges of the one glass component with projecting edge portion abut each other. In this way it is ensured that water, which flows in the direction of the roof or facade slope, does not flow into the joint between the adjacent edges in the chamfered corner regions of the two other glass components, but always flows away from this joint.

An even greater unimpeded incidence of light through the glass panel of the glass components is achieved in a preferred embodiment of the invention in that the glass components of the arrangement of several glass components are each supported by means of a point support.

The limiting effect of the point support on the extent of daylight by the glass components and the extent of the review by the glass roof or glass facade cladding is reduced in an expedient embodiment of the invention in that the point support is supported by a plurality of adjacent glass components on a common support member. The support member may be formed between the glass panel and a structure for the roof or the facade as a spacer.

Advantageously, it can be provided that with the aid of the arrangement of a plurality of glass components, a curved roof or facade cladding is formed with a substantially rounded outer surface. This allows the use of the glass panel for roof or facade constructions in which curved sections are provided.

Appropriately, an embodiment of the invention provide that in the arrangement of several glass components along the bottom of the protruding edge portion of the plurality of glass components each have a sealing element is arranged. This prevents the ingress of water under the overlap and into the joints, and the joints are thermally insulated.

For easy formation of a sufficient interlocking coupling between the plurality of glass components, a preferred embodiment of the invention provide that a recess for receiving a coupling member is provided on the sealing element. The coupling component is in this case attached to another glass component. By receiving the coupling component in the recess on the sealing element, two glass components are positively connected to each other.

In order to avoid the dripping of condensation on the inside of a roof or a facade when using the glass components for the glass panel, is provided in an expedient development of the invention that at the side edges without protruding edge portion of the plurality of glass components each have a collecting element for collecting condensation is arranged. In this way, condensed water, which forms in abutting areas between adjacent glass components or on the underside of a glass component, are collected in the collecting element, so that it can subsequently evaporate.

In an advantageous embodiment of the invention it is provided that the arrangement of several glass components of the glass panel is supported by means of a frame construction, run in the support frame sections along the side edges of the plurality of glass components. As a result, the daylight incidence is hindered by the glass components only to the least extent possible by the support structure.
