Definitions

• the invention relates to a facade system for the cladding of a building according to the preamble of claim 1.
• Such a facade system is known from DE 196 06 906. It essentially consists of a substructure made of posts and transversely arranged transoms. Both elements are made from a hollow profile.
• the filling elements - here laminated glass panes - are arranged in the metal frame formed by mullions and transoms. The conclusion towards the outside is formed by retaining strips which are connected to the metal frame with corresponding fastening screws. To seal the system are in the longitudinal grooves of the post, the
• Bolts and the retaining strips are molded on the inside and outside accordingly.
• the self-drilling fastening screw is inserted as far as possible into a guide and pressure spacer system. After attaching an electric screwdriver, the fastening screw is turned so that it is with a specially trained
• the drill bit is screwed into the nose-shaped profile of the post or the transom.
• This facade system allows simple and therefore quick assembly of the filling elements on the substructure; However, for reasons of strength, it is only suitable for profiles in which penetration of the fastening screw is possible.
• DE 38 23 939 discloses a fastening solution for filling elements on the substructure, in which separate threaded bolts are used. Filling elements are fastened to a hollow profile shown in FIG. 1 via a holding strip. There are threaded bolts on the mullions and transoms shot or welded onto which metal bolts are screwed. The metal bolts have a screw-on area, a conical intermediate area and an area for screwing in fastening screws for the retaining strip.
• Threaded bolts for fastening the filler elements can be used as a hollow profile for conveying fluids. There are no problems with leaks. Furthermore, the substructure is not specifically tailored to a specific facade system. It is therefore inexpensive to manufacture. The flat mounting surface on the outside of the frame also allows the structure to be veneered flexibly. A major disadvantage of this facade system, however, is its complex assembly. As practice has shown, the protruding threaded bolts cannot be attached to the metal frame in true-to-size alignment under construction site conditions. The operator of the fastening device - for example a welding device - can only fix the threaded bolts on the substructure in orthogonal alignment at equidistant intervals with considerable effort. In a workshop assembly the threaded bolt solution the problem arises that the "fixed projecting threaded bolt easily bend or in particular during transport to the construction site as a result of transverse impact load can break away.
• the clamping groove is used to accommodate clamping elements, the clamping foot of which spreads when a spreader sleeve is inserted and thus passes under the beveled flanks of the clamping groove, so that a clamping attachment is produced.
• a holding element for receiving fastening screws for the filling elements is attached. It is with this
• Facade system therefore requires a variety of elements, the use of which increases the assembly effort.
• DE 295 00 286 discloses a facade system which also uses a hollow profile as a substructure, which also has a fastening groove is provided.
• the fastening groove serves as a screw groove section with a groove neck area narrowed with respect to the groove base, in which a fastening screw engages directly on the groove neck area.
• the two facade systems described above are based on the use of specially profiled hollow profiles, which are quite complex to manufacture compared to standard profiles.
• the invention has for its object to provide a facade system that can be flexibly mounted on any substructure made of metal easily and at the same time functional.
• the invention includes the technical teaching that a separate professional rail attached to a substructure is provided for fastening the retaining strips.
• the profile of the profile rail has a screw groove section which interacts directly with fastening screws and at least one further holding section located next to the screw groove section and fixing an inner sealing element.
• the solution according to the invention has the advantage that the facade system can be used by using a separate profile rail on any substructure made of metal, which has a neutral - ie not specially profiled - contact surface.
• the profile rail can be used universally and can be attached, for example, to a metal substructure consisting of T-beams, rectangular profiles or round profiles.
• the facade system is therefore largely independent of the substructure and can be designed flexibly. Since the profile rail specifies both the screw-in points for the fastening screws and the fixing points for the inner sealing elements in the sense of functional integration, assembly errors due to non-compliance with. Assembly dimensions on the construction site excluded. Because the fastening screws directly, i.e. without the use of additional means with the screw groove section - 4 -
• the profile rail is preferably attached to a flat end face of the metal substructure running in the facade plane.
• the outward-facing surface of the metal substructure is used for this. It is also conceivable to attach the profile rail to the flank sides of a metal substructure.
• the profile rail is curved on its base surface facing the metal substructure.
• contact is made with a flat substructure made of metal solely through a line-like support in the bilateral edge area of the bottom surface of the profile rail.
• This design avoids the accumulation of condensation water between the profile rail and the metal substructure and thus allows ventilation, which as a result prevents crevice corrosion in the fastening area between the metal substructure and the professional rail.
• any corrosion protection agent that may be used is thereby made possible to spread in this area.
• the profile rail preferably has two holding sections for the inner sealing element, which are formed by an acute-angled inclination of the two side edges of the profile rail.
• the use of the side edges of the profile rail for holding purposes for the inner sealing element - which could otherwise be pushed out of its desired position under load - is particularly effective. Due to the acute-angled inclination of the side edges, the inner sealing element is pressed underneath them and thus firmly and reliably fixed.

• Profile rail is made from a steel band and is profiled by forming. It can therefore be produced efficiently.
