ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a building glass facade of a building comprising a plurality of glass elements covering at least a portion of a building, at least one of said glass elements comprising a glass pane.
The invention further relates to a clamping arrangement in a facade for holding a glass pane on a facade.
More particularly, the invention relates to a glass pane clamping arrangement for clamping a building glass pane in a facade to a building
2. Background Information
The German Patent No. 195 19 527 A which relates to a device of the type briefly described above, in which a carrier element is connected with the holding device that is provided at the facade of the building, and the carrier element is supported at clamp elements provided at the interior of the building. Support of the carrier element is by way of a bearing portion or head portion of the carrier element, which head portion is journalled in the receiving portion or chamber of the clamp element so as to elastically yield when considered in the longitudinal axial direction of the carrier element, whereby the head portion is additionally journalled in the receiving portion such that it can accommodate lateral play, to thereby allow shifting of the carrier element or, respectively, its head portion, parallel to the plane of the glass pane upon this being impacted by pressure of wind. The elastic yielding of the head portion is afforded by spring washers or a permanently elastic material, the arrangement of which in the bearing chamber continuously effects a reset force on the carrier element or, respectively, the glass pane in the sense of a positioning of the carrier element orthogonally to the glass pane, and this, in the final analysis, causes introduction of stresses into the glass pane. Furthermore, larger tolerances between the holes in the glass pane and the point of connection at the building-side holding device can not be balanced.
German Patent No. 44 00 979 A1 also relates to a device as briefly described above. In this there is described that the clamp element (bearing seat) has, at its mantle surface directed towards the holder, a spherical surface at which is supported a compensation member which, in turn, is configured with a complementing spherical portion. The clamp element has a through bore for receiving therein the clamp screw which connects the clamp elements, and there is also provided a holding screw which passes through a spacer and the compensating member and reaches into the clamp element. This known assembly allows the adjustment of tolerances due to its configuration between the bore in a glass pane and a sub-structure (holder), however, no support of the glass pane in the manner of a resilient elastic support at the holder upon installation is provided for in this reference.
A similar installation is described in German Patent No. 44 45 724 A1, in which the clamp element that is located at the interior of the building has a spherical surface at its surface directed towards the holder, and disposed at this spherical surface is connected a drag or swing bearing of a fastening part of its complementing surface, whereby the swing bearing is held with lateral play in an encasing nut. Upon assembly, again, in this prior art reference no provision is made to permit a relative movement of the pane with respect to the fastening part. Furthermore, European Patent No. 0 784 129 A1 makes known a support of a fastening screw at a holder in which a plate which forms part of the holder is fixed between two planar-convex, lens-shaped elements which are in direct contact with their planar surfaces at the plate, whereby one of the lens-shaped elements with its convex surface is in contact at a clamp element positioned at the inside of the building and the other lens-shaped element is in contact with a nut which receives the fastening screw.
The fastening of highly sensitive glass panes, for example, in conjunction with silicon dice panes, or silicon panes, for the photovoltaic current generation, the known fastening systems do not meet the required demands. Already upon low wind pressures or, respectively, minor deformations due to conduction of heat, the silicon elements break, which is tantamount to the loss of the purpose of the glass plate or pane.
OBJECT OF THE INVENTION
An object of the invention resides in a building glass facade of a building having a provision of a fastening assembly as briefly mentioned in the introduction herein which, for one, permits an adaptation free of tension of the fastening assembly under consideration of even large tolerances of configuration during assembly thereof, and that, as well, upon assembly, there exists a sufficient elasticity between the fastening assembly and the glass pane, and the fastening assembly is capable of being able to absorb wind pressures or stresses due to heat without introduction of tension into the glass pane.
SUMMARY OF THE INVENTION
This object can be achieved with a building glass facade of a building comprising a plurality of glass elements covering at least a portion of a building, at least one of said elements comprising a glass pane, said facade comprising: at least one glass pane; said at least one glass pane comprising a first surface, a second surface, and a hole connecting said first and second surfaces; a clamping arrangement; said clamping arrangement being disposed through said hole; said clamping arrangement including a first clamp device at said first side of said glass pane and a second clamp device at said second side of said glass pane; said clamping arrangement being configured and disposed to secure said glass pane in clamped attitude; a first angle adjustment arrangement; said first angle adjustment arrangement being configured and disposed to adjust an angle of said clamping arrangement; said first angle adjustment arrangement comprising a pivot joint arrangement configured to permit substantially multi-directional pivotal movement of said second clamp device to adjust and hold the position of said glass pane securely relative to a building; said clamping arrangement being supported on said second side of said glass pane by said first pivot joint arrangement; and a second angle adjustment arrangement; said second angle adjustment arrangement being configured and disposed to adjust another angle of said clamping arrangement; said second angle adjustment arrangement being connected in tandem with said first angle adjustment arrangement to adjust for irregularities in said at least one glass pane and for irregularities in said building to thus hold the glass pane firmly in a facade of said building; said second angle adjustment arrangement comprising a pivot joint arrangement configured to permit substantially multi-directional movement of at least a portion of said first angle adjustment arrangement relative to a building to thus adjust for irregularities of said at least one glass pane and for irregularities in said building and to thus firmly hold the position of said glass pane relative to said building.
Claim
1
teaches that an interior clamp element or device has a conical or spherical surface that is provided by a permanently elastic spring member which is disposed on that glass side which is facing away from the glass pane, and against this conical or spherical surface can be set with pre-stressing a complementing or mating surface of the interior or mantle of a bell-shaped housing, whereby between the bell-shaped housing and a securement screw on one hand and a securement screw and the holding device on the other hand, there are provided pivot joints that include rigidity control, in other words, that can be locked in place or position.
The invention further teaches that wind pressure and thermal stresses are absorbed by the elastic support of the bell-shaped housing at the interior clamp element, because also after a concluded assembly there can be achieved a relative movement of the two components with respect to one another, but without the i
