Description

The The invention relates to a holder for fixing at least two adjacent glass panes on a building-side construction element, wherein the holder by means of a carrier displaced and lockable is fastened to the construction element and at least two branch off from the support, each having connected to a glass plate arms.

In the DE 195 19 526 A1 For example, there is described a fixture for mounting glass panels in buildings having a hemisphere surface. In this case, located within an outer part of the hemisphere surface with which a bearing head cooperates with a complementary surface, which is clamped via an inner part relative to the outer part. In this case, the bracing and thus the adjustment of the individual holder is performed prior to assembly of the glass sheet. After installation, the glass pane is fixed within the inner part via a screw, in conjunction with an outer bearing plate. In this holder, no tolerance compensation in the axial direction is possible. Such is given only on the substructure, so that can not be done from the outer side only a fixing of the glass, but it is so that an adjustment is difficult to achieve by other auxiliary personnel in the interior.

A similarly constructed holder for mounting a plate discloses the DE 44 00 979 A1 , Also in this construction, a hemisphere has been used for axial adjustment and thus for tolerance compensation, so that at least translationally a displacement is given.

An attachment assembly for attaching glass plates to a cantilever in conjunction with a substructure for building facades. will be in the DE 44 45 724 A1 played. In this case, a bracket is present on an elongated fastening bolt laterally, which allows the attachment of glass panes. In this construction, only the possibility is given to compensate for angular errors.

A glass pane holder, especially for canopies, is the DE 195 28 489 A1 refer to. In this glass pane holder axial compensation in the form of a threaded sleeve with a bolt which is welded to a substructure, possible. In order to be able to compensate for angular errors, there is a spherical cap connection at the end of the glass pane holder. A disadvantage is the installation in this glass pane holder, as a default setting, in particular with regard to a definition of angles, before installation is not possible.

A generic device describes the DE 297 06 757 U1 , The known device for holding glass sheets has a support which is fixed by means of a screw connection to a construction element designed as a support tube. To compensate for building tolerances a material and costly longitudinal groove is provided within the support tube into which the screw engages slidably and lockable. The holder has two outgoing from the support leg with end reinforcements, which are penetrated by retaining bolts, to each of which one of two adjacent glass panes is connected. The connection of the glass panes is designed such that - using an eccentric sleeve in the region of the bore in the glass pane - a tolerance compensation only in the plane of the glass pane is possible. The angular position of adjacent glass panes to each other is thus rigidly set by the course and the shape of the retaining leg, so that a balance of building tolerances in the extent required in practice, especially in facade construction, is not possible.

Multi-arm mounting systems for glass panels reveal the DE 198 39 419 A1 , the DE 196 23 797 A1 , the DE 693 08 288 T2 and the EP 0 784 129 A1 , wherein the free end of the arms is in each case angled parallel to the course of the plane of the glass sheet, resulting in a large diameter of the holder.

From the DE 199 58 622 C1 and the DE 197 40 878 A1 Furthermore clamping fittings for the clamping of glass panes are known whose formation allows a tolerance compensation with respect to the hole in the glass pane.

The object of the invention is to further develop the state of the art to the effect that a holder is provided on which several adjacent glass panes can be fastened stress-free. It should be possible in particular the attachment of diagonally extending glass panes, ie both angle changes and changes in length should be able to be compensated. In addition to a balance of building tolerances and an individual adaptation to different gradients of facades to be realized. Furthermore, the assembly effort is reduced and the required effort when replacing any damaged glass panes are reduced. Finally, a small-building holder is sought, ie the for the Connection of two adjacent glass panes required diameter of the holder should be minimized.

Is solved the object by the features of claim 1. The dependent claims give a further embodiment of the inventive concept again.

With the feature a) of claim 1, the attachment of the holder optimized on the construction element, d. H. the widened education of the attachment piece guaranteed a good investment of the holder on the construction element, in addition by feature b), d. H. by the assignment of the oblong holes on fastening piece a tolerance compensation between the attachment piece and the construction element given, d. H. with reference to the generic state of Technique may be based on the requirement of a channel-like longitudinal groove on a be omitted as a support tube design element. The according to feature c) from the carrier at an acute angle branching arms and their parallel to the central longitudinal axis The angle of the holder leads to a small diameter of the holder and thus to a cost-effective design. It is the holder in particular for the connection of substantially in a plane running facade panels applicable. Feature d), d. H. on or in the end areas each arm arranged device ensures the required Tolerance compensation in the area of the connection of the individual glass pane or Facade plate to the respective arm of the holder.

In Embodiment of the invention can the arms to achieve a higher stability be connected to each other by a bridge.

Around in a conventional manner, the glass sheets punctiform over a fixing the hole in the glass panes to the holder, is for the end portions of the arms provided a particular embodiment. This embodiment arranged in the end region is characterized by a hole arranged in the end, in which an end piece interchangeable is inserted, which by means of a connecting element via a connector can be clamped with an adjustable abutment. Here is thus realized an adjustability in the form of a head, which is also the Attachment from diagonally extending glass sheets permits. Such an adjustable head can change both angles as well as length changes compensate. In addition to a tolerance compensation can thus also an individual Adaptation to different gradients of facades realized become.

Around To realize a universally adjustable head is located in the end area the possibility a tail to use, which is interchangeable. Simultaneously with the tail is an adjustable with an abutment and a connector fixed and adjustable bearing proposed by means of a connecting element, which the tail reaches through, can be fixed. Alternative types of fastening, such as B. a threaded connection can also be selected. To the largest possible To realize adjustable range, the invention proposes that domes in the form of a hemispherical head with a pan, the one complementary Has shape, find use. So is an adjustability in given in all directions. At the same time, there is also a tolerance compensation present, in the axial direction, for optimal adaptation to reach the glass panes to be fixed.

at the chosen one execution can thus be a pre-setting realized without mounting the glass which are especially big ones Benefits when it comes to larger facades. After this the angular position and the height the outdoor camp By default, the glass is placed on the arm. A further adjustment in all degrees of freedom is now also on patch Glass panes possible. Only after the adjustability is completed, by means of a connecting element, the glass with the adjustable Head connected. Due to the chosen execution it is also possible z. As in a defect of the previously mounted glass, this easy to exchange, without the settings regarding the Inclination of the support and the length compensation need to be corrected.

Next play in the axial direction, the invention also offers the possibility due to the inside of the tail existing adjustment properties, namely an all-round game of the connecting element opposite the penetrated holes, z. B. Errors in the form of incorrectly executed holes, to balance within the glass pane.

Of the Holder according to the invention can z. B. made of stainless steel, brass or light metal be. Preferably, such a holder is inexpensive as a casting manufacture.

The The invention is based on a possible schematic illustrated embodiment closer in the figures explained.

It demonstrate:

1 : A holder in a front view with unilaterally cut arm.

2 : A holder after 1 in the side view.

3 : A holder after 1 attached to a substructure.

4 : A holder after 1 in the plan view.

5 : A partial excerpt from the 1 - the area of attachment of a glass pane.

A holder 1 who has a first arm 2 and a second arm 3 has, in the middle area by a web 9 connected together and at the same time within a fastening piece 4 converge is the 3 refer to. Suggestion is the 3 beyond that, a construction element 5 , z. B. in the form of a steel tube, indicated, to which the holder 1 with corresponding screw elements, which are not shown, through slots 6 can be fastened in a suitable form. From the 2 is the holder 1 can be seen in the side view, which is clear that the attachment piece 4 in the form of a support plate, as well as the 4 plays, is executed.

The in the embodiment (see in particular 1 and 3 ) shown holder 1 indicates that the arms 2 and 3 from a middle line 7 out, and thus from the area of the attachment piece 4 , take an oblique course. The forming angle between the arms 2 and 3 Can be designed differently according to the requirements, so that larger or smaller angles can be performed. Moreover, it is possible besides the arms shown in the embodiment 2 and 3 to choose such an arrangement, in which more arms on the attachment piece 4 are formed positive and positive. By such a measure in particular polygonal facades can be realized with different glass elements.

The poor 2 . 3 have at their free ends an end portion 8th auf, in the embodiment of the 1 and 3 designed so that the end portion parallel to the central axis 7 is trained.

In the end areas 8th the poor 2 and 3 are tails 11 arranged, which are designed interchangeable. The end pieces are attached 11 z. Via connections 24 , The tail 11 serves as a device to the glass panes to be connected 19 tension free on the arms 2 . 3 to fix. Since in large facade constructions especially large tolerances can occur, it is important that the device for fixing the glass sheets allows tolerance compensation in all degrees of freedom. In addition, the device is constructed so that a different position of the glass sheets to adjacent glass sheets on a holder 1 is possible. This is achieved by the end areas 8th (Head) are pivoting and rotating, so different angles of the glass panes 19 to realize each other.

The tail 11 has a cylindrical projection which fits into a bore 10 that are in the end area 8th is immersed. The cylindrical neck of the opposite region of the tail 11 is bell-shaped, so that on the outer contour a spherical shape 22 is available. Because of the tail 11 a cavity 23 also has a spherical course at the end of the cavity 25 , Thus, the spherical gradients 22 and 25 arranged parallel to each other. In the workpiece axis (center line) of the end piece 11 there is a hole 21 so that the spherical gradients 22 and 25 are broken.

Adapted to the spherical shape 22 interacts with this an abutment 12 together, which has a complementary configuration of an inner surface. Thus, here on the principle of ball and pan, the workpieces (tail 11 and counter bearing 12 ) joined together. It becomes clear that when moving the counter bearing 12 different positions can be taken here. Within the counter bearing 12 there is also a hole 30 , which is larger than the hole 21 in the tail 11 , Above the anvil 12 is a connector 13 arranged on a flat outer surface of the anvil 12 , which is opposite the spherical pan, is attached. The connection piece 13 is designed as a round turned part and has a stepped bore in its axis 29 on. The larger diameter of the stepped bore 29 serves to a head of a connecting element 28 take. The connecting element 28 penetrates with its threaded shaft thus the stepped bore 29 , the underlying hole 30 of the counter bearing 12 and at the same time the bore 21 of the tail 11 , The end of the threaded shaft of the connecting element 28 thus protrudes into the cavity 23 of the tail 11 into it. On the end of the threaded shaft of the connecting element 28 becomes a clamping piece 26 that is an internal thread 27 has screwed. This clamp 26 is shaped so that it has a complementary outer contour that leads to the spherical inner course 25 of the tail 11 fits. All drillings 29 . 21 . 20 and 30 are dimensionally so attuned that they penetrate the connecting element 28 with great all-round play this holes can pass through. By this kind of Attachment is next to an adjustment in the adjustment 32 also an adjustment in the adjustment directions 33 possible. This means that at a stationary tail 11 the outer area, in particular with the counter bearing 12 and the fitting 13 , is designed pivotally.

By using a balancing ring 16 on one at the connector 13 located external thread 15 can be screwed, is an adjustment in the direction of adjustment 34 possible. The external thread 15 is located on a cylindrical area 14 of the connection piece 13 ,

To protect the glass 19 there is a glass protection 18 on the collar 17 of the balancing ring 16 , During assembly, thus, the glass pane 19 on the glass protection 18 be placed on it and it can with adjusted glass adjustment and thus a balance of Tole rances or the mounting conditions in all adjustment directions 32 . 33 and 34 be made. Only when the glass 19 is aligned, another glass protection 31 inserted and over a closure 21 a fastening of the glass pane 19 achieved by the fact that the shutter 21 with the compensation ring 16 is positively and positively connected.

The above description shows that in addition to the interchangeability of the end pieces 11 an adjustability in all degrees of freedom and thus adjustment directions 32 . 33 and 34 even with the glass pane on 19 can be realized. Because of the holder 1 at least two arms 2 . 3 may be attached to a holder 1 Also at least two different glass panes are attached.
