Description

SPECIFICATION Structural glazing The invention relates to a structural glazing comprising insulating glazing sealed onto facade profiles, the own weight ofthe glazing being taken up via support profiles.
In the method of construction known technically as "structural glazing" a glazing is secured without a frame on two or four sides to facade profiles, such as facade uprights and facade horizontal members. The glazing consists of a pane oran insulating glazing of two or more panes and is sealed directly onto the facade elements, the sealing not only performing sealing functions but also fulfilling static functions, such as for example the transmission of wind loads (wind pressure and wind suction), and to some extent also bearing the own weight of the glazing.
The sealing is carried out in particularwith a one-component ortwo-component silicone rubber.
To take upthe own weight of large glass areas or heavy insulating glazing, at the lower edge ofthe glazing support profiles are anchored forexampleto afacade horizontal member or crossbeam along a width of about 10 cm and at a distance of 10 cm from the vertical edges of the glazing. These known supportprofilesorsectionsconsistofmetal and ass result cold bridges are formed which impairthe insulating effect of the glazing and of the facade elements.
The invention is based on the problem offurther developing structural glazing so that such cold bridges are avoided.
This problem is solved according to the invention in that between the facade profiles and the support profiles a thermal separation is provided. In particular the support profiles or sections consist of high-strength thermally insulating or poorly thermally conducting plastic. By providing support profiles formed in this manner heat transport from the interior to the facade structure and thus to the outer air and in the converse direction is prevented.
According to a preferred em bodiment the support profiles are made L-shaped and suspended with a vertical leg in undercuts on the cross profiles. On the support profiles support blocks are disposed so that the glazings are mounted at two points to avoid constraining forces.
The support profiles consist preferably of polyamide or polyester and are reinforced with glass fibres.
According to a further preferred embodiment the support profiles consist of at least two plastic strips anchored with a longitudinal edge in grooves to facade profiles and the other longitudinal edges of the plasticstrips are anchored in a plastic or metal profile. In this manner with the cooperation of the facade profiles a thermally insulating composite profile isformed.
The support profiles are preferably disposed encircling the edge of the glazing and connected to each other at the corners. This gives a supportframe forthe glazing which is invisible from the outside and due to the connection at the corner regions has the necessary rigidity.
In afurtherdevelopmentofthe invention on the outer side of the metal profile a rib is formed which serves to supportthe outer pane or plate of a step glazing. The plastic strips likewise consist preferably of glassfibre-reinforced polyamide or polyester.
Examples of embodiment invention will be explained hereinafter in detail with the aid of the drawings, wherein: Figure 7 is a vertical section through a region of structural insulating glazing with a first embodiment of a support profile, Figure 2 is a vertical section through a region of structural glazing with a second embodiment of a support profile, Figure 3 is a first embodiment of a step glazing in vertical section, Figure4is a second embodiment of a step glazing in vertical section, Figure 5 is a further embodiment of a step glazing in vertical section, and Figure6isan embodimentsimilartothe embodiment of Figure 1.
Figure 1 shows a crossbeam or horizontal member 50 of a facade structure to which insulating glazing 52 and 54 is secured without a frame. Between the crossbeam 50 and the glazing 52 and 54 respectively spacing profiles 56 and 58 of silicone are disposed.
At the outer sides ofthe spacing profiles the insulating glazing 52 and 54 is supported via loadbearing sealings 60 and 62 on the facade elements. Panes or plates 64 and 66 of the glazing 52 are held in spaced relationship via a spacer 68 of plastic or metal. The pane or plate 66 is secured via a supporting seal 70 to the pane 64. The glazing 54 is formed analogously to the glazing 52from two panes, a spacer and a loadbearing seal.
Integrallyformed at the front side of the crossbeam 50 is an undercut groove 72 in which a vertical leg 74 of a support profile 76 is suspended.
The support profile 76 engages with a horizontal leg 78 beneath the glazing 52 in orderto supportthe latter via support blocks 80. Between the lower side ofthe leg 78 and the upper side of the glazing 54an intermediatelayer82forexampleofPEfoam is disposed. The space between the spacing profiles 56 and 58 as well as the support blocks 80 and the intermediate layer82 is filled by means of fillings 84 and 86. The support profile 76 consists preferably of a glassfibre-reinforced polyamide or polyester.
Flush with the front sides of the glazing 52 and 54 is a weather seal 88 which covers the support profiles 76, the support blocks 80 and the intermediate layer 82.
The support profiles 76, as in the embodiment of Figure 1, are about 10 cm long and arranged at a distance of about 10 cm from the vertical edges of the glazing 52 and 54.
Figure 2 showsthesecuring of glazing 140 and 142 to a horizontal member or crossbeam 144 of a facade structure. At the front side of the crossbeam 144 a support profile 146 is secured which consists oftwo thermally insulating plastic strips 148 and 150 and a metal strip 152. The plastic strips 148 and 150 are anchored with thickened longitudinal edges 149 and 151 in undercut grooves 153 and 155 respectively on the crossbeam 144. At the opposite likewise thickened longitudinal edges of the plastic strips 148 and 150 the metal strip 152 is anchored and comprises for this purpose undercut grooves at the inner side. The support profile is covered with a weather seal 154. The securing ofthe glazing 140 is via a loadbearing sealing 156 and the glazing 142 is secured via a loadbearing sealing 158.The glazing 140 consists of two glass panes or plates 160 and 162 which are spaced via a spacer 164 of plastic or metal.
The pane 162 is connected via a loadbearing sealing 166to the pane 160. The glazing 142 is made analogously to the pane 140. Between the glazing 140 and 142 and the crossbeam 144 spacing profiles 168 and 170 are provided. The glazing 140 rests on support blocks 172 of plastic which lie on the support profile 146. Between the glazing 142 and the support profile 146 an intermediate layer 174 of PE foam is disposed.
Figure 3 shows a section through a crossbeam 180 of a facade structure to which glazing 182 and 184 is secured via loadbearing seals 186 and 188. The glazing 182 consists oftwo glass panes 190 and 192 which are connected via a spacer 194 of metal or plastic and a loadbearing seal 196. The glazing 192 is constructed as step glazing, i.e. the glass plate 190 is ofgreater dimensions than the plate 192 so that it projects beyond said plate 192 atthe edges. Atthe front side ofthe crossbeam 180 undercut grooves 198 and 200 are formed into which thickened longitudinal edges ofthermally insulating plastic strips 202 and 204 are anchored. The outwardly directed edges of the plastic strips 202 and 204 are anchored in undercut grooves of a metal strip 206.
The support profile 208 formed from the plastic strips 202 and 204 and the metal profile 206 serves to take up at least part of the own weight of the glazing 182 and furthermore to secure the pane 190 orthe front pane of the glazing 184 by means of a loadbearing sealing 210 and 212 respectively. The pane 192 of the glazing 182 rests on support blocks 214which are disposed in the region of the ends of the support profile 208. Between the lower side ofthe support profile 208 and the upper edge ofthe inner pane ofthe glazing 184 and the loadbearing sealings an intermediate layer 216 is provided and preferably consists of PE foam. The loadbearing sealings 210 and 212 are spaced apartvia an intermediate layer 218.The space between the lower edge of the pane 190 and the upper edge ofthe front pane ofthe glazing 184 is sealed by means of a weather seal 220.
The embodiment shown in Figure 4 corresponds substantiallyto that of Figure 3 with the difference that at the front side of the metal strip 206' ofthe support profile 208' a rib 222 is formed which serves to take uptheweightofthefront pane 190' via support blocks 224. Beneath support rib 222 an intermediate layer 226 is disposed. The space between the pane 190' and the front pane of the glazing 184 is sealed by means of a weather seal 220'.
As in the embodiment of Figure 2the support profiles ofthe embodiments of Figures 3 and 4 are preferablyformed asclosedframeatthefrontsides of crossbeams and uprights in order to provide the necessary rig idity when the glazing rests on the lowerframe strips. In the embodiments according to Figures 3 and 4 an optimum securing ofthe glazing to the facade elements is achieved because both panes of the glazing are connected independently via loadbearing seals to the facade elements and support profiles.
Figure 5 shows an embodiment of an insulating glazing 232 supported via a support profile 230 corresponding substantiallyto the embodiment of Figure 4. There are differences intheform ofthe support rib 234 which is longerthan the support rib 222 and is arranged flush with the outer side of the glazing, and in the arrangement of spacing profiles 236 and 238 between the inner pane 240 of the glazing 232 and the outer side of the facade profile 242 and between the outer pane 244 of the glazing 232 and the profile strip 246 which is connected via insulating strips 248 and 250 to the facade profile 242.
Figure 6 shows an embodiment ofstructural glazing 262 and 264 disposed on a facade profile 260, the glazing 262 being supported via a support profile 266 which consists of a poorlythermallyconductive plastic. The support profile 266 is ofT-shaped cross-section and is inserted in a C-shaped groove at the front side of the facade profile 260.
Thefrontface of the longitudinal leg 278 ofthe support profile 266 runs flush with the front face of the glazing 262 and 264. Between the facade profile 260 and the glazing 262 and 264 in addition to loadbearing seals 270 and 272 spacing profiles 274 and 276 are provided. The glazing 262 and 264 and the securing thereof to the facade profile 260 and the support profile 266 is otherwise analogous to the embodiment of Figure 1.
