Definitions

  • the invention relates to a facade profile according to the preamble of claim 1.
  • facade profiles For the attachment of facades on the outside of buildings, a variety of facade profiles are usually used, which are used on the one hand as a continuous, vertical post and on the other hand as a transom attached between the posts. In this way, a grid-like support structure is built, to which plate-shaped elements are attached to form the facade surface.
  • the plate-shaped elements for example glass panes, are usually fastened by largely strip-shaped fastening elements which run parallel to them on the outside in the area of the posts and transoms and are fastened to them by means of fastening screws.
  • fastening screws To attach the fastening profiles by means of numerous fastening screws, at least one screw channel, seen in cross section, is usually formed in the facade profiles.
  • a stainless steel facade profile with at least one screw channel is described in DE 197 52 620.
  • the use of stainless or austenitic stainless steel for facade profiles is advantageous.
  • austenitic stainless steel is generally permitted as stainless steel. In the Federal Republic of Germany, this is done as part of a general building inspectorate approval.
  • the dominant manufacturing process for facade profiles is cold forming, especially roll forming and folding.
  • the basic material is usually 1-2 mm thick sheet metal. These material thicknesses are achieved by cold rolling. Due to the pronounced degree of strain hardening of austenitic stainless steels, very high strength values are already available in the semi-finished product (tensile strength, but above all proof strength and hardness).
  • the walls delimiting the screw channel are usually formed by a double material.
  • the roll-formed stainless steel sheet is turned over by 180 ° at the free ends of the U-shaped screw channel.
  • This strong reshaping increases the already comparatively high strength of the stainless steel sheet used, particularly in these areas, so that it is difficult to screw commercially available stainless steel screws into a screw channel designed in this way.
  • deformation of the screw thread occurs, so that only low extraction forces and low overtorques are achieved.
  • DE 296 03 707 describes a metal facade, in particular for conservatories, in which the glass panes are installed in this way should be ensured that the pane is not stretched and tends to break. Therefore, the weight of the glass panes or metal plates used should be optimally introduced into the metal facade.
  • one or more glass supports are provided on the fastening channel, which support the glass panes.
  • the weight of the glass panes can be introduced into the metal facade via the glass supports.
  • the screw channel in technology is usually made of a particularly solid material or with a particularly large material accumulation. There is only a line contact between the screw and the screw channel, over which, in addition to the total wind load on the facade panels, even still the load must be absorbed by the facade panels themselves. Therefore, a particularly high-strength material has always been used in the area of the screw channel in the prior art.
  • the invention has for its object to provide a facade profile made of steel, which can be designed with as little effort as possible that it meets the requirements both in terms of the stability of the profile and the stability of the screw channel, while at the same time an easy and safe screwing of fastening screws in the screw channel is permitted.
  • the facade profile according to the invention is characterized in that the screw channel is also made of a steel material, preferably stainless steel.
  • the screw channel is provided on a separate component that is directly connected to the supporting profile of the facade profile. This component can already be firmly connected to the support profile during the manufacture of the facade profile, preferably by welding. No components or the like that are to be handled separately are necessary.
  • connection steel-steel for example by welding can be easily manufactured. Furthermore, there is no fear of impairment of the corrosion resistance.
  • the steel material of the screw channel has a lower strength than the profile material.
  • the basic idea of the invention is to use, at least for the screw channel, a stainless steel material which is different from the materials usually used for the facade profiles.
  • a stainless steel material which is different from the materials usually used for the facade profiles.
  • For the support profile a comparatively thin-walled, extremely hard austenitic stainless steel can be used in the usual way due to the given requirements with regard to the formability, the detailed contouring and for economic reasons.
  • a softer steel material than the material of the support profile is used for the component provided separately for this purpose, which has the screw channel. This avoids deformation of the screw thread, and this enables sufficient pull-out forces and sufficient overtorque.
  • the stainless steel material of the screw channel it is preferred for the stainless steel material of the screw channel that it has a lower initial strength and / or a lower degree of cold rolling and / or a lower degree of work hardening, which can be achieved, for example, by the choice of a suitable alloy .
  • a lower degree of cold rolling can be achieved, for example, by choosing a thicker wall thickness for the area of the screw channel, so that the stainless steel sheet used for forming the screw channel is deformed to a lesser extent during roll forming, and one compared to the usual 1 to 2 mm thick stainless steel sheet sets less solidification.
  • the use of hot-rolled stainless steel for the area of the screw channel is also advantageous, since the deformation of such stainless steel results in a hardening that does not reach a level at which the screwing in of fastening screws and their secure mounting is impaired.
  • each with the Support profile are welded.
  • the screw channel can be formed in a simple manner from the materials described with the specified properties.
  • a U-profile can be used, for example, in a groove-like recess formed in the support profile and welded to the edge abutting the groove.
  • two free legs on the support profile with a gap between them, into which a U-profile forming the screw channel is inserted, which is connected to the ends of the two free legs by welding.
  • a largely W-shaped profile can be placed on two free legs of the support profile, which results from a U-shaped profile in that each of the two free legs of a U-shaped profile has further legs parallel to the free legs and extend outside of it back to the level of the connecting portion between the two free legs.
  • two U-profiles formed next to one another and connected to one another by the connecting section are obtained, which are plugged onto two free legs formed on the support profile in such a way that the respective free leg extends between the two legs of the U-profiles described.
  • Fig. 1 can be seen in the sectional view of the facade profile 10 according to the invention, which consists of the actual support profile 12 and the screw channel 14 formed thereon.
  • the support profile 12 is roll-formed from a stainless steel sheet, so that there is an overall closed shape.
  • the support profile 12 shown only partially in the drawing extends into the area below FIG. 1, so that a hollow profile with a square or rectangular cross section is formed overall.
  • the support profile 12 as open, U-shaped profile, designed as a T or double T profile.
  • a screw channel 14 is formed, which according to the invention is made of a different, softer material than the support profile 12.
  • the screw channel is formed by two strips or strips 16 made of flat material, which are largely perpendicular to the end face. These are fastened in parallel to one another by welds 18 on the end face of the support profile 12, so that a fastening screw can be screwed in between the strips 16 in such a way that their threads come into engagement with the surfaces of the strips 16 facing one another.
  • the material of the strips 16 is sufficiently soft by the measures described above, so that, for example, commercially available fastening screws made of stainless steel, which, if necessary, can additionally be diffusion-hardened, can penetrate with their thread into the material of the strips 16, so that they are secure in the Screw channel are anchored.
  • the screw channel 14 is formed instead of the two strips 16 by a U-shaped profile 20, which in the exemplary embodiment shown is firmly connected to the support profile 12 on both sides by foot welds 18 on the outside.
  • a suitable steel material can be selected for the U-profile 20 forming the screw channel 14, regardless of the material of the support profile 12, which does not impair the fixing of the screws.
  • FIG. 3 An alternative fastening option for the U-profile 20 is shown in a top view in FIG. 3.
  • this has a plurality of recesses 24, which in this case are largely rectangular, viewed in plan view.
  • welding spots 18 can be formed in the area of the recesses 24 in the middle leg 22 and do not have to be created on the outside of the U-profile 20, as is the case in the exemplary embodiment in FIG. 2.
  • the welds 18 can be carried out at any edges of the recesses 24 which extend through to the front surface of the support profile.
  • FIG 4 shows a further embodiment of the facade profile 10 according to the invention, in which the screw channel 14 is formed by two angle profiles 26, which are largely L-shaped. These two angle profiles 26 are arranged mirror-symmetrically to one another, so that respective first legs are spaced apart from one another and extend parallel to one another and form the screw channel 14. The respective second legs extend away from each other and are attached to the support profile 12 by welds 18.
  • FIG. 5 shows an alternative type of attachment to the support profile 12 for such an embodiment with two angle profiles 26.
  • the angle profiles 26 Similar to the U-profile 20 shown in FIG. 3, the angle profiles 26 have a plurality of recesses 24 which are designed as incisions on the legs of the angle profiles 26 pointing away from one another. Because the welding spots 18 with the support profile 12 can be formed closer to the screw channel 14 at the recesses 24, this modification can also achieve that the fastening points in the form of the welding spots 18 are loaded by lower moments. At the same time, the areas remaining between the recesses 24 ensure sufficient stability against the outward pivoting of the angle profiles 26 when the Fixing screws in the screw channel 14 formed between the profiles 26.
  • the support profile 12 is provided on its end face with a groove-shaped or channel-shaped depression 28 which has flanks which run largely perpendicular to the end face and can be easily formed during the roll forming of the support profile 12.
  • the U-profile 20 made of a suitable other material can be inserted with a precise fit and connected to the supporting profile 12 by welds 18.
  • Fig. 7 shows a similar measure for positioning a U-profile 20 forming the screw channel 14.
  • the support profile 12 is not designed as a closed hollow profile, but is provided on its end face with an opening through two free, largely perpendicular to Front leg 30 is limited.
  • the U-profile 20 is inserted into the gap or the space between these legs 30 and connected to the support profile 12 by welds 18.
  • the weld seams 18 are provided in contact with the free ends of the legs 30 and against the respective outside of the legs of the U-profile 20.
  • the legs 30 are made shorter, so that they are connected to the legs of the U-profile 20 at a point along the longitudinal extent of the legs 20 similar to the embodiment of FIG. 6.
  • FIG. 8 shows a further embodiment of the facade profile 10, in which a largely W-shaped profile is used to form the screw channel 14, the W profile 32 appearing as an inverted W as shown in FIG. 8.
  • the profile 32 results from the in Fig. 7 shown U-profile 20 to a certain extent that parallel to the two legs of the U-profile 20 are provided outside the two legs and parallel to these further legs 34, which together with the free legs of the U-profile, from which was thought to define an intermediate space into which the respective leg 30 of the support profile 12 extends.
  • the W profile 32 is fastened by welding at the ends of the two legs 34.
  • the profile 32 forming the screw channel 14 is not only in a lateral direction with respect to the support profile 12 (ie from left to right) 8, but also in the depth direction, ie from top to bottom according to FIG. 8).
  • the profile 32 can also be thermoformed so that the strength existing before the deformation is restored.
