Description

The present invention relates to a facade and / or light roof construction for buildings according to the preamble of claim 1.

From the AT 398 796 a glass holder for an insulating glass element for glass facades of buildings is known which has laterally projecting retaining pins, which are each inserted into a groove on an insulating glass pane. The glass holder further has a fastening strip which can be inserted into a screw groove of the facade profile. For a mounting of the glass holder, a passage for a screw is provided, which can be screwed into a screw groove on the profile to fix the glass holder and the surface elements, in particular insulating glass discs by clamping to a seal. In this prior art glass holder is disadvantageous that it is relatively difficult to assemble. Because during assembly of the strip-shaped projection must be threaded into the screw groove and in addition the lateral retaining pins are inserted respectively into the grooves on the insulating glass pane. This is usually done by angling the glass holder when the surface elements, in particular insulating glass panes are suspended only loosely. However, this procedure is relatively complicated and it is not possible to subsequently mount a glass holder with fixed surface elements, in particular insulating glass, which has retaining pins on both sides.

The DE 37 14 629 discloses a facade in which a holder is provided which can be fixed via a screw on a profile. The holder includes laterally projecting arms which engage in grooves on a spacer between two discs.

Also the US4799344 reveals a similar facade.

It is therefore an object of the present invention to further develop the facade and / or roof construction of claim 1 such that the glass holder for mounting insulating glass elements to profiles is easy to assemble, preferably also a subsequent installation with specified insulating glass elements should be possible.

This object is achieved with a glass holder with the features of claim 1. Thereafter, the glass holder has on the side facing the profile on a substantially flat contact surface, which can be applied to the end edges of the grooves of the profile. Preferably, a strip-shaped projection is provided on the underside of the glass holder, which is in particular slightly inserted into the screw groove for centering the glass holder.

If the glass holder on the side facing the profile has a substantially flat bottom, which is attachable to attach the glass holder on the screw groove, the glass holder can be easier to assemble, as no web in the screw and at the same time a lateral support arm in the groove of an insulating glass must be inserted. Rather, the glass holder can be placed from above on the screw and only needs to be attached laterally with the support arm in a corresponding groove of the insulating glass. Especially if only one holder arm is provided on the glass holder, this threading process can be carried out relatively easily.

Since on the underside of the glass holder further comprises a strip-shaped projection is provided for centering the glass holder in particular slightly (this means just so far that the centering takes place, in particular less than 2 mm, for example 0.5 mm) can be inserted into the screw groove, It further simplifies assembly by automatically aligning the glass holder over the neck when tightened. Preferably, in addition to the approach side insertion bevels are provided, so that in an eventual inclination before tightening takes place centering in the desired position.

Preferably, the glass holder is further rotatably disposed at the end edges of the screw groove to bring the at least one lateral support arm into engagement with the groove in the insulating glass element.

Due to the rotatable design of the glass holder, this can be easily mounted, since the glass holder can be placed on the screw groove of the profile, wherein the or the support arms are aligned parallel to the screw, and then positioned over a 90 ° rotation of the glass holder so that the or the support arms engage in the grooves of the insulating glass elements.

The position of the insulating glass elements and the profile can already be fixed for subsequent installation and the glass holder can be easily mounted even in confined spaces. The glass holder can be produced with a comparatively small size, which also leads to cost savings.

According to the invention, two grooves are provided in the bearing surface into which the end edges of the screw groove can be inserted when positioning the at least one lateral holding arm in the groove of the insulating glass element. Through such grooves an assembly aid is given, which indicate to the fitter the correct orientation of the lateral holding arms or in the grooves, as during the rotational movement, a slight locking of the glass holder takes place. For such a mounting aid, it is also sufficient if instead of the grooves only a central projection is provided on the glass holder, which engages in the screw groove, as soon as the strip-shaped projection is aligned parallel to the screw groove. The provision of grooves in the contact surface has the advantage that over-rotation of the glass holder becomes more difficult, in particular when the end edges of the screw groove can be inserted into the grooves substantially in a form-fitting manner.

Preferably, the screw channel in the glass holder has a receptacle for a head of a screw, which is arranged below the groove of the glass holder. Thereby, the screw can be sunk during assembly to leave the groove free, so that the glass holder can be grasped and rotated by a tool for mounting. The screw head does not hinder this process because it is located in the receptacle below the groove. After mounting the glass holder, the groove can then be used to insert a gasket.

The groove is therefore preferably undercut, so that a sealing foot can be fixed in the groove.

If a retaining arm is provided on opposite sides of the glass holder and the glass holder is formed symmetrically along a median plane parallel to the groove of the glass holder, incorrect assembly is avoided since both retaining arms can be equally screwed into the respective groove of an insulating glass element. With two retaining arms, insulating glass elements can be fixed on opposite sides of the glass holder, while a glass holder having only one holding arm is provided on the edge of an insulating glass element on a facade construction.

A façade construction with insulating glass elements is also provided which, at least in sections, each have a groove at the edge and are fastened to profiles via a plurality of glass holders according to the invention. Adjacent to the glass holders, an insulating strip is arranged in the screw groove on the profile, so that a high thermal insulation is achieved in the region of the profile.

Preferably, the glass holder and the insulating strip have approximately the same height and there is a seal with a sealing foot in the groove of the glass holder and adjacent thereto in a groove an insulating set. As a result, the seal can be fixed circumferentially around an insulating glass element and the seal can be set with high accuracy, wherein the contact pressure of the sealing lip is sufficient for a seal. The usual in the prior art filling the gap between two insulating glass elements with silicone or other filling material can therefore be omitted, since the attachment of the seal in the insulating strip and the glass holder provides adequate sealing and insulation.

If a continuous groove for fixing a seal is provided on the side facing away from the profile of the top of the glass holder, the support structure can be sealed in a simple manner. Preferably, the groove is on the glass holder formed undercut, so that a sealing foot can be pulled into the groove. For a particularly good thermal insulation, an insulating strip can additionally be provided adjacent to the glass holder in the screw groove, in which a groove is provided on the side facing away from the profile, into which a continuous seal can be inserted, which then on the insulating strip and the glass holder is fixed. This support of the seal makes it possible to dispense with a subsequent filling of the gap between two surface elements with silicone. Because the seal is consistently supported so that corresponding sealing lips with a certain bias to the end faces of opposing surface elements can be applied, so that no additional sealing is required.

Preferably, the glass holder via two screws on the profile can be fixed, so that the glass holder is held against rotation on the profile. The heads of the screws can be arranged sunk substantially below the groove in the glass holder, so that the functionality of the groove, for example, to receive the seal is maintained.

For receiving particularly large loads, the transition between the at least one holding arm and a side wall of the glass holder is rounded, preferably with a radius of more than 5 to 10 mm.

According to an independently viewable variant, a holding arm of the glass holder which can be inserted into a groove of an insulating glass pane, viewed in the axial direction of the profile is formed curved. As a result, the support arm can be inserted at an angle into the groove, and the insulating glass pane can be mounted at the appropriate angle to the profile or to an adjacent insulating glass pane. If both sides of the profile of the support arm of a glass holder is curved in each case, the surface elements can be arranged at the desired angle to each other, for example in a corner region with 90 °. As a result, they can also be used in so-called structural glazing constructions, in which fasteners do not have the outer pane of the insulating glass pane protrude. Due to the curvature on the support arm of the glass holder can also be used for different angles, namely, when the curved end portion is shortened so that only a portion of the curvature is present, so that the insulating glass is attached at a different angle relative to the profile. As a result, only one glass holder needs to be kept ready for different angles.

According to a preferred embodiment, the at least one retaining arm has a central section extending parallel to the bottom section and an end section curved towards the profile. If the curved portion of the support arm would immediately extend from a contact surface on the profile to one side, there could be too limited space for the attachment means on the profile, since the surface elements should be received with a certain play in the lateral direction. The rectilinear central section thus bridges the necessary lateral distance between attachment of the glass holder and engagement in the groove of the insulating glass pane.

Preferably, grooves are provided on the curved end portion of the support arm for marking an angle of curvature. As a result, at the construction site, the glass holder can be easily adapted to the desired angle for fixing the insulating glass pane, wherein optionally the holding arm is cut along a groove. In this case, the curved end portion may be formed wavy in cross-section and form a trough a mark for separating an unneeded part of the end portion and a wave crest form a linear contact surface for the wall of the groove an insulating glass pane. Such a wave crest also has the advantage that a certain tolerance compensation can take place, for example when the insulating glass pane is slightly pivoted or moved as a result of pressure or heat loads. The spherical sections of the wave crests cause a line-shaped surface to bear against the wall of a groove of the insulating glass pane in order to compensate for small tolerances.

For a simple attachment of the glass holder, a protruding centering projection for insertion into a screw groove on the profile is provided on the bottom portion. This results in a precise positioning of the glass holder on the profile.

If the bottom portion is strip-shaped and can then be fastened by means of two screws on the profile, a security against rotation of the glass holder is achieved, and it can be removed high loads.

Preferably, the glass holder has a hollow chamber in which the heads of screws for fixing the glass holder are receivable. Thereby, the holding arm can connect to the top of the hollow chamber, so that outwardly a flat surface is formed, which is particularly well suited for the attachment of filling material, in particular because the filling material can also be just positioned and does not curl.

According to the invention, a support structure for angularly arranged surface elements is provided with a corresponding glass holder. The curvature of the glass holder may be formed such that adjacent surface elements, for example, at an angle between 90 and 160 ° can be fixed. Preferably then the grooves are held on the profile for receiving a seal via a web on the profile, which can be changed by a bend, the orientation of the groove on the profile. This eliminates high storage costs for different profiles and glass holder, since with one and the same glass holder or profile different angles of the surface elements can be realized to each other.

According to a further variant adjacent to the glass holder in each case an insulating strip is mounted in the Schraubnut, in which on the side facing away from the profile side a groove is provided in which an over the glass holder and the insulating strip extending continuous seal between the adjacent surface elements is fixed. The arrangement of a seal eliminates the need to Gap between the surface elements to be filled with silicone, since the seal is supported at least on the insulating strip and sufficient clamping forces can be provided to seal the gap via sealing lips or elastic sealing strips, even if a significant burden of weathering occurs. By supporting the seal on the insulating strip sagging, which could lead to leaks, safely avoided.

Preferably, the seal on opposite sides of sealing lips, each of which bears resiliently against a front edge of the insulating glass pane. The sealing lips can ensure a secure seal even in extreme weather conditions. In this case, the sealing lips may be bent in the direction away from the profile, so that when pulling the seal, the sealing lips are automatically aligned in the prestressed position.

According to a further embodiment of the invention, a continuous groove for fixing a seal is provided on the top of the glass holder facing away from the profile. Thereby, the seal can be defined throughout in the groove of the insulating strip and the groove of the glass holder, so that a substantially uninterrupted support of the seal is given. The groove in the glass holder is preferably aligned with the groove of the insulating strip.

For a simple installation of the seal, the groove is formed undercut on the glass holder and the insulating strip, so that a retraction of the seal without tools is possible. When the sealing foot is arranged with play to the bottom of the respective groove, the sealing foot can also be pressed slightly over the later mounting position when retracting the seal, so that the gasket is not accidentally stopped, for example, because the gasket foot too early on the ground the groove is present. Preferably, the groove bottom and the sealing foot are V-shaped, whereby a simple mounting and centering is achieved.

According to a further embodiment, the seal on opposite sides on first sealing lips and second sealing lips, which rest in each case on a front edge of an insulating glass pane. Preferably, the first arranged on the side facing away from the profile side sealing lips are longer than the second sealing lips, so that the second sealing lips represent only a kind of security, for example, when the first sealing lips are damaged. The longer sealing lips also form the appearance of a silicone-sealed gap also, which has the advantage that both types of sealing can be used side by side.

In FIG. 1 a facade construction 1 is shown in which insulating glass elements 3 are fixed to a profile 2 as surface elements. This facade construction 1 can be used both in the area of an exterior wall as well as in roof glazing. The insulating glass elements 3 are in the edge region on seals 4, which are arranged in grooves 5 of the profiles 2.

Between the grooves 5, a screw groove 6 is provided which is formed of two opposing webs, on which corrugations are provided on the inside. The Schraubnut 6 serves in addition to the inclusion of fastening means for receiving an insulating strip 7, which has a directed towards the outside groove 70. The Schraubnut 6 also serves to define a glass holder 9 according to the invention and can also be used to provide cover shells not shown here, which can hold the insulating glass elements 3 on the outside.

The insulating glass elements 3 have on the outside a circumferential groove 8 in the edge region, which is integrally formed on a spacer profile, the between two glass panes is positioned at the edge. The spacer profile with the groove 8 is held over filling material between the glass sheets.

On the glass holder 9 laterally projecting support arms 13 are formed, in which case two support arms 13 per glass holder 9 are provided. It is also possible to form only one holding arm 13. The width 11 of the glass holder 9 or the holding arms 13 is smaller than the distance 12 between two insulating glass elements 3. In the glass holder 9, a screw 22 for carrying a screw 10 is provided so that the glass holder 9 can be fixed in the Schraubnut 6 of the profile 2 ,

For assembly, the glass holder 9 is first equipped in the position marked A with a screw 26, wherein a screw head 26 is inserted into a receptacle in the glass holder 9. The glass holder 9 can thus be gripped on a groove 16 by a tool and inserted into the gap between two insulating glass elements 3 (position B).

As soon as a contact surface 14 of the glass holder 9 rests on the end edges of the screw groove 6, the glass holder 9 is rotated by about 90 °, so that the holding arms 13 each engage in a groove 8 of an insulating glass element 3. Subsequently, the screw 10 is completely screwed into the screw groove 6 in order to fix the glass holder 9 and thus the insulating glass elements 3 to the profile 2.

In FIG. 2 the glass holder 9 is shown in the mounted position. The glass holder 9 rests with a contact surface 14 on the front edge of the screw groove 6. The retaining arms 13 engage in the groove 8 of the insulating glass elements 3, so that they are pressed with a certain contact pressure against the seals 4 to be held on the profile 2.

To the outside, a seal 15 is provided, which engages with its foot in a groove 16 of the glass holder 9. The seal 16 has sealing lips 27, which are pressed with a certain bias against the end faces of the insulating glass elements 3 and ensure adequate sealing. The seal 15 is held with the seal base adjacent to the glass holder 9 in the groove 70 in the insulating strip 7, so that the seal 15 is held securely throughout and ensures adequate sealing. It is not necessary to additionally fill the rear area of the seal with silicone.

In FIG. 3 the glass holder 9 according to the invention is shown in section. The glass holder 9 has a contact surface 14, in which two grooves 17 are recessed. The grooves 17 have approximately a width according to the two end edges of the screw groove 6, so that the screw groove 6 can be inserted into the grooves 17 substantially positive fit. The grooves 17 serve as an assembly aid, so that upon rotation of the glass holder 9, the correct alignment of the glass holder 9 is audible or palpable by a slight click. It is also possible to provide only a central projection instead of the guide grooves 17, which engages in the screw groove 6.

The glass holder 9 has two holding arms 13, each comprising a thinner web 18 and a crowned end 19. The spherical end 19 has the advantage that a defined contact surface of the support arm is provided in the groove 8 of the insulating glass elements 3. Furthermore, the insulating glass elements 3 can perform slight movements in the mounted position, or by considerable wind loads. Then the insulating glass element 3 can be moved around the crowned end 19 slightly.

The rotatable glass holder 9 has centrally a receiving groove 16 which is provided with a V-shaped bottom 20 which is formed corresponding to the foot of the seal 15. The V-shaped groove 16 has lateral undercuts 21 for the positive retention of the seal 15. The glass holder 9 is constructed so that the position of the groove 16 has approximately the same height as the groove 70 of the insulating strip 7. As a result, the seal 15 retains a continuous support surface. Furthermore, lateral groove walls 24 are also provided on the glass holder 9, which contributes to a secure hold of the seal 15.

In the glass holder 9, a screw channel 22 is also centrally provided, which has a small strip-shaped projection 23 in the end region on the side facing the profile 2, which clamps the fastening means, such as the screw 10, so that they can not be lost during assembly , The screw 22 also has a receptacle for a head 26 of the screw 10, so that it can be arranged concealed below the groove 16. For this purpose, the screw 22 is provided in the upper area with an enlarged opening, wherein the head 26 of the screw 10 is supported on bevels 25 in the screw 22. The function groove 16 is not affected by the recessed arrangement of the screw head 26.

The rotatable glass holder 9 may be made of metal or other suitable material. In the illustrated embodiment, the glass holder 9 is provided with two holding arms 13. For the edge-side attachment of an insulating glass element 3, a glass holder 9 is sufficient, which has only one holder arm 13.

An in FIG. 4 Supporting structure 101 shown comprises a profile 102 on which a plurality of surface elements 103 are fixed. The surface elements 103 are clamped in the edge region of a seal 104, which are retracted into a groove 105 of the profile 102. The metal, for example aluminum or steel profile 102 further comprises a screw groove 106, in which an insulating strip 107 is inserted. However, the insulating strip 107 is not formed continuously, but at intervals has interruptions, so that a glass holder 109 can be attached to the screw 106.

The glass holder 109 has one or two laterally projecting holder arms 113, which are each inserted into a groove 8 arranged on the edge side on the surface elements 103.

As in FIG. 5 can be seen, the attachment of the glass holder 109 via a screw 124 which is screwed into the screw 106 of the profile 102. At the side facing away from the profile 102, a groove 170 is formed both on the insulating strip 107 and a groove 116 on the glass holder 109, which are arranged approximately at the same height and receive a seal 115. The seal 115 is held continuously in the grooves 170 and 116 and has sealing lips 127 which abut against end faces of the surface elements, in particular insulating glass panes 13 and ensure adequate sealing. Due to the continuous support of the seal 115, it is no longer necessary to additionally fill the gap between the surface elements, in particular insulating glass panes 103, with silicone.

A glass holder 109 is in the FIGS. 6 and 7 shown. The glass holder 109 has a substantially flat bottom 114, on which a strip-shaped projection 117 is provided for centering in the screw 106. On the strip-shaped projection 117 lateral slopes 112 are arranged as Zentrierungshilfe. As a result, the insulating glass pane 103 together with the glass holders 109 can easily be placed on the profile 102.

The glass holder 109 further includes a lateral support arm 113 which is formed of a thinner web 118 and a spherical head 120. Due to the thickened head 120, which comes into contact with the groove 108 in the insulating glass pane 103, a slight inclination of the surface elements 103 can be achieved up to a maximum of 10 °, without adversely affecting the holding function of the glass holder 109. It can also be slight curves of the support structure to be built with this glass holder 109.

For a particularly large force transfer, the transition between the support arm 113 and a side wall of the glass holder 109 is rounded at 119. The radius is preferably chosen larger than 5 or 10 mm, so that loads can be transferred well over the rounded area.

The glass holder has two holes 111 into which screws 124 can be screwed to fix the glass holder 109 to the profile 102. The

Screws 124 can be received sunk in the glass holder 109, wherein the bore 111 is widened below the groove 116 by a slope 123 (countersink) and the head of the screw 124 is received substantially below the groove 116.

The groove 116 of the glass holder 109 is formed in the bottom portion V-shaped and has inclined wall elements 122, which are formed according to the inclination of the sealing foot of the seal 115. Between the seal base and the slope 122 some play is provided so that the seal 115 can be better fed into the groove 116. On opposite side walls 110 of the groove 116 projections 121 are further provided so that the groove 116 is formed undercut and the seal 115 can hold permanently.

The glass holder 109 shown is preferably made of metal or other suitable material. In the embodiment shown, only one support arm 113 is provided. It is also possible to provide on the opposite side also a holding arm 113 to attach two surface elements 103 with the glass holder 109.

In Fig. 8 a support structure 201 is shown in the form of an outer wall or roof glazing, which is designed as a so-called structural glazing construction, which has no visible attachment parts outside. The supporting structure 201 comprises a profile 202 and surface elements, in particular insulating glass panes 203, which has an outer glass pane 233 with an edge region projecting beyond an inner glass pane 234. Between the glass sheets 233 and 234, a spacer 230 is provided, on which a groove 232 is arranged. The groove 232 comprises planar aligned groove walls 231 which are used to fix the insulating glass pane 203.

The surface elements 203 abut with the inner glass pane 234 on a seal 204, which are retracted in a groove 205 of the profile 202. The grooves 205 are connected via a web 225 with the profile 202, which is bent relative to the profile 202 according to the orientation of the insulating glass 203.

On the profile 202, a screw groove 206 is further provided for receiving insulating strips and fastening means, wherein the glass holder 207 according to the invention is also fixed to the screw groove 206. For this purpose, one or more screws 20 are provided, which fix the glass holder 207 clamped on the profile 202 via a screw head 221.

Between a gap 208 between adjacent outer glass panes 233, a sprayable joint seal 209 is provided. So that this joint seal 209 can not enter the glass fold, a so-called prefiller 210 is inserted between the glass holder 207 and the joint seal 20 9.

At the in Fig. 8 embodiment shown, the surface elements 203 are arranged at an angle of 90 °. The glass holder 207 has in each case a holding arm 211 with a curved end section 223, which is inserted into the groove 232 at the end in each case. Relative to a plane of the screw channel, the insulating glass pane 203 is mounted over the glass holder 207 at an angle of 45 °, wherein surface elements 203 are attached to both sides of the screw groove 206.

As in Fig. 9 As shown, the same glass holder 207 can also be used to secure surface elements 203 at a different angle to a profile 202. The curved end portion 223 has been shortened in this embodiment, so that only a part of the end portion engages in the groove 232 of the insulating glass pane 203. Accordingly, the outer glass pane 233 of the insulating glass pane 203 protrudes only slightly beyond the inner glass pane 234, and the groove 205 is aligned over the web 225 at a different angle. The two adjacent surface elements 203 are arranged at an angle of 160 °. It is also possible to have the surface elements 302 in any other one Angle over the glass holder 207 adjacent to each other on a profile 202 set.

As in Fig. 10 can be seen, the glass holder 207 includes a bottom portion 212, on which a strip-shaped protruding centering projection 213 is formed. The spigot 213 is inserted into the screw groove 206 and ensures correct positioning of the glass holder 207 on the profile 202, wherein the side walls of the spigot 213 may be slightly oblique to ensure a positive or clamping down the screw groove 206.

The glass holder 207 further includes a hollow chamber 214, which serves to receive the heads 221 of the screws 220, so that the heads 221 do not project beyond the glass holder 207. At a top 219 of the hollow chamber 214, a central portion 222 of the support arm 211 connects, which is flat and extends perpendicular to the median plane of the screw 206. At this central portion 222, the curved end portion 223 connects.

The curved end portion 223 is wave-shaped and includes a plurality of troughs 216 or grooves and wave crests 217 bulging outwardly. The troughs 216 form marking aids which indicate which angle is reached from a central plane through the curved end section 223. In the illustrated embodiment, an angle of 45 ° is included over the last crest 217, so that this last crest 217 is suitable for attachment to a 90 ° corner. Should adjacent surface elements, in particular insulating glass panes 203, however, be mounted at a smaller angle, then the curved end section 223 can be correspondingly shortened, whereby a certain tolerance compensation can take place due to the bulbous configuration of the wave crests 217 and in a certain area a linear contact surface of a wave crest 217 the wall 231 of the groove 232 of the insulating glass pane 203 is given. By marking the individual Angular ranges avoid assembly errors, and glass holder 207 can be easily shortened on site.

The wave-shaped design of the curved end portion 223 offers, in addition to the linear load transfer, the further advantage that length expansions of the insulating glass pane 203 can be easily compensated, since the wave-shaped bearing surfaces have only low frictional resistance.

As in Fig. 11 As shown, the glass holder 207 includes two openings 218 in the upper area into which screws 220 can be inserted. Corresponding smaller diameter holes are provided in the bottom portion 212 of the glass holder 207. The glass holder 207 thus has an outer flat bearing surface, since the heads 221 of the screws are recessed in the hollow chamber 214 and thus the prefiller 210 can be placed well on the glass holder 207.

The glass holder 207 shown can preferably be extruded from metal, for example aluminum, and then cut to the desired length. Other materials can be used for the production.

In the embodiment shown, the curvature at the end portion 223 is circular. It is also possible to provide a curvature with different radii on the glass holder 27.

An in Fig. 12 shown further support structure 301 for a structural glazing construction comprises a profile 302, are fixed to the surface elements 303. On the profile 302, seals 304 are drawn into grooves 305, against which the surface elements, in particular insulating glass panes 303, bear in a clamping manner. For fastening the surface elements, in particular insulating glass panes 303, the profile 302 has a screw groove 306, are fixed to the glass holder 310 and an insulating strip 307. The glass holders 310 have one or two laterally projecting support arms 311, which are provided in a groove 309 of an insulating glass pane 303 intervene. The groove 309 is arranged on a spacer 308 between two glass panes of the insulating glass pane 303 and may optionally extend over the entire length or only over a partial area.

For the mounting of the glass holder 310 screws 312 are provided, which are screwed by a screw in the glass holder 310 in the screw 306 on the profile 302. Further, a groove 313 is provided on each glass holder 310, which serves in the assembled state for fixing a seal, which extends along the insulating strip 307 and the glass holder 301. During assembly, however, the groove 313 can also be used for the engagement of a clamping device of a tool.

How out Fig. 12 can be seen, the glass holder 310 is first aligned so that the support arms 311 parallel to the screw groove 306 and can be inserted between a gap 314 of two surface elements 303. Then, the glass holder 310 is rotated by 90 °, so that the holding arms 311 engage in the groove 309. Subsequently, the glass holder 310 is fixed via the screw 312. The surface elements 303 are held circumferentially over several glass holders 310 on profiles 302.

For assembly, a tool is used, as in Fig. 13 is shown schematically. The tool comprises a handle 320 which has an opening 322 on the side remote from the profile 302. On the side facing the profile 302, a clamping device 321 is provided which protrudes from the handle 320. For assembly, a screw 312 is first inserted into a passage in the tool, and then the glass holder 310 is prefixed to the clamp 321 by clamping. Then, the tool is inserted together with the glass holder 310 in the gap 314 between the surface elements 303 and rotated over the handle 320 by 90 °. In this case, an abutment flange 325 arranged on the handle bears against the surface elements 303. The rotation of the handle 320 is clearly visible through the strip-shaped design of the handle. Then, by means of the bushing arranged in the tool, the screw 312 is replaced by means not shown Screwdrivers set. On the handle 320, the abutment flange 325 is formed on the underside. The clamping device 321 is positioned on a tubular portion 326 and thus protrudes from the handle 320 for insertion between two surface elements 303.

As in Fig. 14 As can be seen, the bushing comprises a first cylindrical portion 322 with a larger diameter, a frusto-conical portion 323 and a second cylindrical portion 324 with a smaller diameter. The frusto-conical portion 323 serves as a guide, so that the fastening bolt 312 and / or a screwdriver can be inserted more easily into the section 322 and then automatically aligned during insertion.

In the illustrated embodiment, the bushing includes a screw head receptacle 330 and a smaller diameter cylindrical portion 329 than the adjacent regions. As a result, a screw 312 can be held in the receptacle 330 between the tool and the glass holder 310 without it being possible to lose it by mistake. The tapered cylindrical portion 329 prevents the screw 312 from slipping through the tool.

In Fig. 15 the tool is shown in side view, in particular, the clamping device 321 is clearly visible. The clamping device 321 has wedge-shaped inclined to each other extending side surfaces 328, which extend at an acute angle α, preferably between 1 and 10 °. The side surfaces 328 may be roughened to allow the glass holder 310 or other object to be clamped well.

In FIGS. 16 and 17 the tool is again shown in perspective. The clamping device 321 is formed from two projections attached to the tubular portion 326, which can then engage in a groove 313 of the glass holder 310 or in a recess on an object. The handle 320 is as Hollow profile formed and has receptacles 327 on which spacers or other molding devices can be mounted.

In the illustrated embodiment, the tool is made of plastic, which may also be transparent, so that the object to be mounted remains visible. It is also possible to use other materials for the tool.

Furthermore, the tool and method of assembly has been explained in more detail with reference to the definition of surface elements 303 on a profile 302 for structural glazing constructions. However, the tool can also be used universally for mounting other objects.

An in FIG. 18 Supporting structure 401 shown comprises a profile 402 on which a plurality of surface elements, in particular insulating glass panes 403 are fixed. The surface elements 403 are fixed in the edge region by clamping on a seal 404, which are drawn into a groove 405 of the profile 402. The metal, such as aluminum or steel profile 402 further includes a screw 406 into which an insulating strip 407 is inserted. However, the insulating strip 407 is not formed continuously, but at intervals has interruptions, so that a glass holder 409 can be attached to the screw 406.

The glass holder 409 has one or two laterally projecting holder arms 413, which are each inserted into a groove 408 arranged on the edge side on the surface elements 403. The insulating glass pane 403 comprises an inner glass pane 430 and an outer glass pane 431, between which a spacer 432 is arranged, on which the groove 408 for receiving the holding arms 413 of the glass holder 409 are integrally formed.

As in FIG. 19 can be seen, the attachment of the glass holder 409 via a screw 424, which is screwed into the screw groove 406 of the profile 402. At the side facing away from the profile 402, a groove 470 is formed both on the insulating strip 407 and a groove 416 formed on the glass holder 409, which are arranged approximately at the same height in alignment and receive a seal 415. The gasket 415 is held continuously in the grooves 470 and 416 and has outwardly bent sealing lips 427 which abut against end faces of the outer glass pane 431 of the surface elements 403 and ensure adequate sealing. By the resilient engagement of the sealing lips 427 and tolerances in the width of the gap between adjacent surface elements can be compensated. Due to the continuous support of the seal 415, it is no longer necessary to additionally fill the gap between the surface elements 403 with silicone.

The glass holder 409 has holes into which screws 424 can be screwed for fixing to the profile 402. The screws 424 can be received sunk in the glass holder 409, wherein the head of the screw 424 is arranged sunk substantially below the groove 416.

The groove 416 of the glass holder 409 is formed in the bottom portion V-shaped and has inclined wall elements, which are formed according to the inclination of the sealing foot of the gasket 415. Between the seal base and the slope some play is provided so that the seal 415 can be better fed into the groove 416. On opposite side walls of the groove 416 further inwardly directed projections are provided so that the groove 416 is formed undercut and the seal 415 can hold permanently.

In FIG. 20 the seal 415 is shown in cross-section. The seal 415 comprises on opposite sides first sealing lips 427 and on the side facing the profile 402 shorter second sealing lips 419, which also bear against the front edge of an insulating glass pane 403.

The gasket 415 further includes a compressible gasket leg 418 having laterally protruding projections 417 which provide a secure fit in an undercut groove 416 and 470, respectively. In the area of the sealing foot 418, a hollow chamber 421 is provided, so that the sealing foot 418 easily compress and feed into grooves 416 and 470. On the side facing outward, the seal 415 is arched in a visually appealing manner, so that together with the sealing lips 427 results in an outer W-shaped contour.
