Abstract:
The invention relates to a facade and/or a roof comprising a metal framework. Preferably, the case bays of said metal framework can be provided with insulating glass panes. The vertical member profiles and the cross member profiles comprise sealing grooves ( 5, 6, 9 ) for sealing strips ( 10, 13, 13.1 ) on which said insulating glass panes ( 102 ) can be supported. The bottoms of said sealing grooves ( 5 ) for the sealing strips ( 10 ) and, preferably, the bottoms of the receiving grooves ( 8 ) for the leakage water of the cross member profiles ( 2 ) rest on the sealing grooves ( 6, 9 ) of the sealing strips ( 13, 13.1 ) of the vertical member profiles ( 1 ). The single-part or multi-part sealing strips ( 13, 13.1 ) of the vertical profiles are higher than the searing strips ( 10 ) of the cross member profiles in such a way that the sealing strips ( 10, 13, 13.1 ) of the cross member profiles and the vertical member profiles occlude in a common plane. Said facade and/or roof is characterised in that at least one of the sealing strips ( 10, 13, 13.1 ) of the cross member profiles ( 1 ) and/or the vertical member profiles ( 2 ) comprises at least one drainage channel, preferably a condensate channel ( 11, 18 ).

Description:
BACKGROUND OF THE INVENTION 
     The invention relates to a facade and/or roof and a sealing strip. 
     In spite of improved thermal insulation of glass panes and panels for facades constructed from cross members and vertical members and well as for roof window structures and verandas, the collection and diversion of condensate in the marginal regions of the panes is still of particular importance. 
     In particular, when the sloped roof areas or facades are inclined towards the horizontal, the condensate must be collected and drained in the lower region of the inclined area. The horizontal and sloped cross member profiles are primarily affected by the draining and/or dripping condensate. 
     The German patent DE 34 19 538 describes a facade and a roof embodied in a metal-glass structure, wherein the vertical and cross member profiles each have condensate water channels arranged on both sides of the marginal edges. 
     The planes of the condensate water channels are arranged such that, when the cross member profile is connected to the vertical member profile, the channel bottom of the condensate channel of the cross member profile is supported on the boundary wall of the condensate channel of the vertical member, whereby the condensate is transferred from the cross member profile to the vertical member profile and then discharged at a suitable location by the condensate channel of the vertical member. As a result of the overlap, the condensate channel of the vertical member profile extends unrestricted to the bottom area or to a drainage region of a roof. 
     This construction has proven to be non-optimal, because the cross member and vertical member profiles have to be designed with a greater width than technically required for the glass support, since the corresponding condensate channels also have to form a partially open channel beyond the glass support region, as viewed in the vertical direction. 
     This represents a increased material consumption for the profile and a more visible surface, which then increases the coating costs. In addition, wider profiles are inconsistent with the architectural quest for smaller profiles. 
     Moreover, the cross member profile has to be notched in order to overlap the condensate water channel of the cross member on the vertical member, which places a particular burden on the processor and significantly adds to the cost. 
     SUMMARY OF THE INVENTION 
     It is therefore an object of the invention to provide a structurally simple and reliable condensate collection and discharge system, so that the overall widths of the metallic vertical member profile and of the metallic cross member profile are identical. 
     The invention solves this object by a facade and/or roof with a metal framework having frame areas which can preferably be provided with insulating class panes, wherein the framework has vertical member profiles and cross member profiles which are oriented perpendicular to the vertical member profiles, the vertical member profiles and cross member profiles include sealing grooves for sealing strips on which the insulating glass panes can be supported, the vertical member profiles and cross member profiles further include receiving channels for leakage water, the bottoms of the sealing grooves for the sealing strips and preferably the bottoms of the receiving channels for the leakage water of the cross member profiles are positioned on the sealing grooves of the sealing strips of the vertical member profiles, and the one-part or multi-part sealing strips of the vertical member profiles have a greater overall height than the sealing strips of the cross member profiles, so that the sealing strips of the cross member and vertical member profiles terminate in a common plane, wherein at least one or more sealing strips of the cross member profiles and/or of the vertical member profiles has/have at least one drainage channel, preferably a condensate channel. 
     Unlike the state-of-the-art, at least one of the sealing strips of the cross member profiles and/or the vertical member profiles includes at least one drainage channel, preferably a condensate channel. 
     Preferably, the condensate channel is formed as one piece of the sealing strip in a cost-effective manner without adversely affecting the installation. This embodiment of the invention thus obviates the need for, installing an additional element, although the invention can be modified by adding useful elements recited in the dependent claims. 
     It has proven to be particularly advantageous, if the condensate channel of the cross member profile extends directly or indirectly to the glass support area of the vertical member profile and is designed to drain into channels of the vertical member profile. This arrangement advantageously retains the conventional drainage techniques, while at the same time reducing the number of components. 
     According to a separate modified embodiment, the invention solves the object also by a sealing strip for cross member and vertical member profiles, in particular glass support sealing strip for a facade and/or a roof, wherein at least one or several sealing strips of the cross member profile and/or the vertical member profile have a drainage channel which is formed as one piece on the glass support area of the seal, in particular for condensate, and preferably has a substantially rectangular U-shaped cross-section. 
     Since the condensate channels are now unexpectedly no longer associated with a metal profiles, but in a simple and cost-effective manner with the sealing strips, it is possible to flexibly adapt to different installation situations, in particular where the facade transitions into inclined and horizontal regions—i.e., transitions info roof window regions or where excessive generation of condensate is expected. The shape of the sealing strip according to the invention makes it possible to reliably discharge large quantities of condensate. 
     The condensate channel of the sealing strip is constructed at right angles, which is visually pleasing and functional, and preferably dimensioned according to the subject matter of the additional dependent claims, so that it has a particular advantageous relationship to the other sealing strips of the vertical member profiles. 
     With the sealing strip of the invention, the same profile combination can be used in the vertical section of the facade and in the horizontal roof window section. 
     The seal which consists of elastic material can be easily processed using a knife and scissors and ensure a high degree of leak tightness, without placing an excessive burden on the installer. 
     The condensate channel on the sealing strip of the cross member compensates optically the height differences of the seals relative to the vertical member. 
     The finished length of the seals need not be overly exact, since a small excess length of the seals is elastically compensated by compression over the entire length. The joints between seals and between the corner and/or end pieces are elastically sealed even more robustly by a slight excess length of the seals of preferably 1-2%. 
     In particular, only one sealing strip may be required for a cross member with a condensate channel of horizontal cross member profiles with straight sloped surfaces. This seal has to be installed on the surface of the cross member profile towards the upwardly sloped area and is typically sufficient for collecting and diverting the condensate. Glass panes with a low R-value and fill plates and/or roof constructions with a relatively small slope may require that the frame areas along the circumference or at least on three sides are provided with condensate collecting channels. 
     The sealing strip with the condensate channel can be applied wherever condensate generation is expected, in particular on the underside of inclined glass planes and fill plates, where the condensate drains towards the cross member profile. 
     Additional components, which form the subject matter of additional dependent claims, can be used to provide a tight sealing plane and glass support in a simple manner. 
     Additional embodiments of the invention are recited in the dependent claims.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     FIG. 1 shows a part of a facade embodied in a metal glass structure with a metal framework of vertical member profiles  1  and cross member profiles  2  which are oriented at an angle and are installed on the vertical member profile  1 . 
     The end faces of the vertical member profile  1  and the cross member profile  2  each have a center rib  100  which is configured for securing cover plates  101 . These cover plates  101  hold inserts, such as plates, for example insulating glass panes  102 . 
     The end faces of the cross member profile  2  are notched in such a way that the profile wall  3  which faces the insulating glass pane and forms the bottom for the leakage water channel  4  and the sealing groove  5 , is supported on the installed state of the sealing groove  6  of the vertical member profile  1 . 
     The sealing groove  6  of the vertical member profile  1  is located—when viewed from the building side of the facade—above a cavity  7 . The sealing groove  6  and the cavity  7  together delimit the leakage water channel  8  of the vertical member profile  1 . 
     In the exemplary embodiment shown on the right-hand side of the vertical member profile  1  in FIG. 1, the sealing groove  6  of the vertical member profile  1  can also be formed so as to be open towards the bottom, so that the sealing groove  6  extends into the region of the cavity  7  and the sealing groove  6  is combined with the cavity  7  to a sealing groove  9  which combines a function of the sealing groove and the cavity. 
     The sealing strip  10  with the actual glass support region  10   a  and the sealing foot  10   b  of the cross member profile  2  advantageously includes a condensate channel  11  which is formed on the glass support region  10   a  as one-piece and has preferably a rectangular shape. 
     The channel wall of the condensate channel  11  facing the sealing element of the sealing strip  10  sealingly contacts the outer surface of the cross member profile  2 . The underside of the channel bottom  2  is aligned or flush with the underside of the profile wall  3 . In principle, the condensate channel  11  can have other shapes, for example a round cross-section, although a rectangular shape is preferred because of the advantageous visual effects and stability. It is important that the channel cross-section is dimensioned so as to support a sufficiently large water discharge and provide adequate rigidity. Particularly advantageous is also the one-piece construction of the sealing strip  10 . Various multi-piece constructions of the sealing strip are also feasible. 
     The sealing strip  10  extends into the region of sealing strip  13  of the vertical member  1  where it contacts an end sealing element  14  to which the glass support seal  13  of the vertical member  1  is connected or formed. 
     The end sealing element  14  has an extension  15  to the sealing strip  10  of the cross member profile  2 , which corresponds to the condensate channel  11  and encompasses the condensate channel  11  on the side and from below, thereby supporting and aligning the condensate channel  11 . 
     The end sealing element  14  includes a condensate channel which faces the cross member profile and terminates in the alignment region of the sealing strip  13  in a closed hollow channel, from which a drain  16  extends downwardly, penetrating the channel bottom  17  of the sealing groove  6  and terminating in the cavity  7 . Alternatively, the drain  16  extends into the sealing groove  9  which is open towards the bottom. In this case, the drain  16  in the end sealing element  14  may be omitted, so that only a drain opening is provided in the sealing element of the end sealing element  14 . 
     The facade structure depicted in FIG. 1 with the novel seal provides a cost-effective condensate drainage system of simple construction which operates reliably and separately from the leakage water drainage of the leakage water channels  4  and  8 . 
     FIG. 2 shows a facade structure, wherein the vertical member and cross member profile  1 ,  2  are identical to that of FIG.  1 . In addition to FIG. 1, however, the sealing strip  21  of the vertical member profile  1  also includes a condensate channel  18  which is formed directly on the glass support region of the sealing strip, which is once more encompassed and supported by an extension  19  of an end sealing element  20 . 
     The end sealing element  20  includes a kind of foot, which engages with and is formfittingly secured in both the sealing groove  5  of the cross member profile and the sealing groove  6 ,  9  of the vertical member. 
     The end sealing element  20  furthermore includes a channel which is flush with the condensate channel  11  and lengthens the condensate channel and extends through the leg of the end sealing element which is flush with the sealing strip  21 . 
     In this way, the leakage water channel  8  of the vertical member is directly connected with the condensate drainage system, i.e., the condensate is discharged directly into the leakage water drainage system. 
     The end sealing element  20  can include a drain extension  22  towards the leakage water channel  8 . 
     According to FIG. 2, the drainage system for the condensate and the leakage water are no longer separate, but combined into an all-inclusive system. 
     This makes it also possible to reduce the air exchange between the leakage water channel  8  and the condensate channel  11 ,  18  to a minimum. For this purpose, a fibrous filter insert  25  (see above) is inserted in the channel that connects the condensate channels with the leakage water channel  8  of the vertical member. The filter insert  25  impedes air exchange, but also diverts the accumulating condensate to the leakage water drain through adhesion and through the capillary action of the filter material. 
     The two different drainage systems of FIGS. 1 and 2, meaning the combined or separate drains, as well as the arrangement of a condensate channel  18  on the sealing strip  21  can be interchangeably employed in various ways. 
     The sealing strip  10  with the condensate channel  11  for the cross member profile  2  should be arranged on sloped surfaces at least on the topside of the cross member profile. This seal can also be placed on both sides of the cross member profile if the roof surfaces or the facades have a smaller slope. The same applies to facades where condensate accumulated on the topside of cross member profiles can be collected and drained through the condensate channel. 
     The construction and function of the facade drainage system will now be described in more detail with reference to the additional drawings. 
     FIG. 3 shows a top view of a profile crossing point between, vertical member  1  and cross member  2 . The sealing strip  21  with the integrated condensate channel  18  is disposed on the vertical member  1 . The sealing strips  10 ,  21  are connected via the end sealing element  20 . The condensate channels  11 ,  18  are surrounded and supported by the extensions  15 ,  19 , which also provide a sealing function. In addition, correspondingly larger adhesive surfaces suitable for connecting the seals with the end sealing element are obtained. 
     FIG. 3 shows the separate drainage of leakage water into the space  9  and the cavity  7  under the sealing strip  21 . Also visible is the drainage channel  23  which extends beyond the condensate channel  11  to the end sealing element  20  and to the drain  16 . 
     FIG. 4 shows, unlike FIG. 3, also is sealing strip, or in this case a glass support seal  13 , for the vertical member  1 , however here without a condensate channel. 
     FIG. 5 shows a top view of a facade of the type depicted in FIG.  2 . The drainage channel  24 , which is aligned with the condensate channel  11  and terminates in the leakage water channel  8  of the vertical member  1 , is clearly visible in this top view of a profile crossing point This drainage channel is filled with a filter insert  25  which essentially prevents air exchange between the leakage water channels  8 , also referred to as joint spaces, and the condensate channels, also referred to as interior spaces. Only the condensate is diverted through adhesion on the fibers and capillary action in the channels formed by the fibers. 
     FIG. 6 corresponds essentially to the structure of FIG. 1, except that the sealing strip  13  is implemented without a condensate channel and drainage is achieved—as in FIG.  5 —via the drainage channel  24  and the installed filter insert  25 . 
     According to FIG. 7, only the sealing strip  13  has to be inserted into the vertical member  1 . The sealing strip  10  with the condensate channel  11  contacts an end sealing element  26  which extends the cross member seal  10  into the region of the vertical member profile  1 . The end sealing element  26  engages with a foot section in the sealing groove  5  of the cross member profile wherein it is affixed together with the seal  10 . The width of the end sealing element  26  corresponds to the total width of the sealing strip  10 , including the condensate channel  11 , so that the end face of the seal  13  can be sealingly urged against the outside of the end sealing element  26 . In extension of the condensate channel  11 , the end sealing element  26  includes a drainage channel  27 , before which a condensate channel  11  can be connected. The drainage channel  27  terminates in a drain  16  which directs the condensate into the space  9  or the cavity  7  of the vertical member, separate from the leakage water. 
     FIG. 8 shows, like FIG. 7, the crossing point of a vertical member profile  1  with the cross member profile  2 . Shown is an end sealing element  28  which is provided in the overlap region between the cross member profile and the vertical member and which has a drainage channel  27  that terminates in the drainage channel  8  or in the joint of the vertical member profile. This end sealing element  26  is particularly suited for cross member profiles that are joined at an angle, since the end sealing element  26  can be cut to the joining angle of the profiles. 
     The surface of the end sealing element  26  facing the sealing strip  13  is smooth and can be sealingly attached to the glass support seal  13 . The drainage channel  27  is provided with the filter insert  25 , as previously shown in FIGS. 5 and 6. 
     FIGS. 9 and 10 further show that the end sealing element  26  is mainly intended for the crossing points where the cross member profile  2  abuts the vertical member profile at an angle. For this purpose, the end sealing element is configured to be correspondingly longer than for a square joint, so that it can be easily adapted to different configurations. 
     FIG. 9 shows the aforementioned angled joint between the cross member profile and the vertical member profile and therefore corresponds to the aforedescribed FIG.  7 . Only the end sealing element  26  and the sealing strip  13  are matched to the joining angle of the profiles. 
     FIG. 10 is a top view of an angled joint between a cross member and a vertical member, while corresponding in all other aspects to the description of FIG.  8 . Only the end sealing element  28  and the sealing strip  13  of the vertical member are configured to match the crossing angles. 
     FIG. 11 is a perspective exploded view of the structure of a connection between a cross member and a vertical member of a facade. The cross member profile  2  overlaps the vertical member profile  1  in the region of the sealing groove. The difference in height is compensated by the different heights of the seal  10  and the seal  13 ,  13 . 1 . This difference in height is also compensated by the end sealing element  14 . Shown is an end sealing element  14  and a sealing strip which does not include the condensate channel  18  depicted in FIG.  2 . The end sealing element  14  is clearly visible. The legs of the end sealing element included in the joining region with the respective sealing strip  10 ,  13  centering cams  29 ,  30 ,  31  which cooperate and engage with corresponding cavities in the glass support profiles, thereby fixing the position of the components relative to each other. The cams simultaneously increase the size of the contact surfaces, enabling the components to be joined later with an adhesive. 
     The drain  16  or the drainage extension  22  with the drainage channel  27  that is closed by a filter insert  25  can be arranged either on the end sealing element  14  or on the end sealing element  20 . 
     FIG. 12 also shows a perspective exploded view of a crossing point of a facade with cross members and vertical members. This Figure shows the end sealing element  26  which also has a centering cam  29  that cooperates with a cavity of the glass support profile  10 . The glass support profile  13  is elastically supported on the outer surface of the end sealing element  26 . 
     For separately draining the condensate, the end sealing element  26  can be provided with the drain  16  or, if the leakage water is added, with the drainage channel  27  and the filter insert  25 . 
     FIG. 13 shows the end sealing element  14 , representative also of the end sealing element  20  which has been described in detail above. Instead of the drainage channel  27  and the illustrated sealing insert  25 , the end sealing element is to be provided with the drain  16  for separate condensate drainage. 
     The same applies also to FIG. 14 which shows the end sealing element  26 . 
     Instead of using corner sealing elements or end sealing elements, the sealing strip  10  including the condensate channel  11  can extend into the overlap region of cross member  2  and vertical member  1  (not shown here). The sealing strip  13  of the vertical member profile is then extended to the outside of the condensate channel  11  under pretension, wherein an adapter element is inserted in the condensate channel  11  in the region of the sealing strip  13  which compensates, on one hand, the difference in overall height to the glass support and closes the condensate channel  11 , so that the condensate can be diverted through a stamped opening in the channel bottom of the condensate channel  11  to the space  9  under the sealing strip  13  or into the chamber  7 . 
     The adapter element can also form a channel in which a filter insert  25  is the arranged which effects drainage into the joint and/or the leakage water channel  8 . 
     In particular in the last described embodiment, but also in the embodiments depicted in FIGS. 7,  8 ,  9 ,  10 ,  12  and  14 , which all include the end sealing element  26 , the height difference between the cross member profile and the vertical member profile to the glass support plane can also be compensated by a two-piece seal  13  on the vertical member (see FIG.  18 ). Contemplated is here a combination of an aluminum base strip and a corresponding sealing strip  10  without a condensate channel. 
     The structure of the sealing strips, and in particular the sealing strips that have an attached or integrally formed drainage channel, will now be described in detail. 
     FIG. 15 shows an enlarged cross-sectional view of the sealing strip  10 , wherein the plane X of the sealing strip  10  is supported on the two upper edges of the sealing groove  5  and the sealing strip  10  is held by the sealing foot formfittingly in the cross member profile  2 . A rib  10   c , which is formed directly on the side of the glass support region  10   a  and has essentially the height of the glass support region  10   a , is connected to the sealing structure. The exemplary sealing structure corresponds essentially to the conventional glass support region  10   a  with a sealing foot  10   b  integrally formed for engagement in the sealing groove  5 , which (not shown here) can also be hingedly connected via a type of film hinge, so that the glass support region can be relatively easily separated from the foot region in the overlap region with the vertical member profile. The condensate channel  11  which is open to the insulating glass pane but is otherwise rectangular and has a substantially U-shape, is formed on the stable rib  10   c , which encompasses the outer lateral edge of the sealing groove  5 . The condensate channel  11  is formed by the channel walls  12 ,  200  and the channel bottom  130  and is supported on the cross member profile  2  with the side  12  facing the cross member profile  2 . The plane Y of the channel wall  12  oriented towards the sealing structure hence forms also the lateral attachment and contact plane on the cross member profile  2 . 
     The sealing structure and/or the glass support region  10   a  have—and seen from the plane X, i.e., the top edge of the sealing groove  5 —a height “a”, whereas the leakage water channel that extends from the plane X to the bottom edge of the channel bottom  130  has the dimension “b”. The effective overall height “H” of the sealing strip  13  for the vertical member profile  1  is composed of the height of the glass support region and the dimension “b” of the leakage water channel, i.e., the sum “a+b”. 
     The dimensions a and b are selected such that the channel bottom  130  of the leakage water channel is positioned on the top edges of the sealing groove  6  of the vertical member profiles. In addition, the channel wall  200  is perpendicular to the channel bottom  130  and in a particular embodiment forms a part of the contact surface for the sealing strip  13 . 
     In an advantageous embodiment, the height h of the channel wall  200  is equal to the dimension “b” of the condensate channel  11 . 
     FIGS. 16 to  18  enable a comparison of the overall dimensions of the different seals. FIG. 16 shows the sealing strip  10  for the cross member profile  2 , FIG. 17 shows the sealing strip  13  for the vertical member profile, and FIG. 18 shows a combined sealing unit  13 . 1  for the vertical member profile. FIGS. 16 to  18  are laid out next to each other to clearly indicate that the glass support profile  10  for the cross member profiles including the condensate channel  11  has the same overall height as the vertical member seals according to FIGS. 16 and 17. 
     Accordingly: H=a+b. 
     According to FIG. 18, the sealing strip or the sealing strip  13 . 1  are formed as two pieces, i.e., the sealing strip includes a sealing strip  21  made of a sealing material and a joint reduction profile  220  which is typically made of the same material as the cross member profile and the vertical member profile, i.e. possibly or preferably fabricated of aluminum. 
     The joint reduction profile  220  has a height b which in a particularly advantageous embodiment of the channel wall  200  corresponds to the height of the seal  10 . 
     The sealing strip  21  into this configuration can extend to the channel rib or bottom of the sealing strip  10 , wherein the sealing foot of the sealing strip  21  is removed in the overlap region with the condensate channel  11 . The corresponding drainage channel is filled by the filter insert  25  or closed by a sealing element. This ensures that the condensate water is drained into the leakage water channel  8  or the cavity underneath the sealing strip  7 ,  9  of the vertical member profile. 
     FIG. 19 shows a section of the sealing strip  10 , wherein a shaped sealing element  23  can be inserted into the end sections of the sealing strip  10  in the region of the condensate channel  11 . This shaped sealing element  23  extends the condensate channel to the upper sealing surface of the sealing strip  10  and also terminates flush with the channel wall  20 , so that the sealing strip of the vertical member profile forms a smooth contact surface for an end seal in the overlap region between the cross member profile  2  and the vertical member profile  1 . In the present example, the sealing strip  10  is extended, to the overlap region of the profiles, without the need for additional corner sealing elements or end sealing elements. 
     The shaped sealing element  23  leaves a channel open so that a stamped opening in the bottom of the condensate water channel  11  is accessible for draining the condensate. 
     Unlike the shaped sealing element shown in FIG. 19, the shaped sealing element  240  of FIG. 20 includes a continuous channel so that the condensate can be directed into the leakage water reservoir of the cross member profile. The filter insert  25  made of a synthetic PA filter medium can be inserted into this open channel. 
     FIG. 21 shows again a facade crossing point or crossing region. The sealing strip  10  is once more extended into the overlap region, so that the condensate channel is supported on the sealing groove of the vertical member profile. 
     The shaped sealing element  23 ,  240  forms the closed support surface, so that the sealing strip  13  can sealingly contact the sealing strip  10  and/or the condensate channel  11 .
