Definitions

  • the invention relates to a steel support profile for a facade and a set of support profiles with associated inner sealing strips.
  • Façade profiles made of steel are usually produced in technology by cold forming, especially roll forming and folding. Due to the degree of strain hardening of steel, especially tenitic stainless steels, there are already very high strength values in the semi-finished product.
  • the walls delimiting the screw channel are mostly formed by a doubling of material.
  • the roll-formed sheet steel is folded over by 180° at the free ends of the U-shaped screw channel. This strong forming increases the already comparatively high strength of the sheet steel used, particularly in these areas, so that it is difficult for standard steel or stainless steel screws to penetrate satisfactorily into a screw channel formed in this way. In some cases, deformation of the screw thread can also occur, so that only low extraction forces and low stripping torques are achieved.
  • the pamphlet EP 0 955 420 B1 proposes the provision of a separate screw channel profile, which is directly connected to the support profile of the facade profile. This component can already be firmly connected to the support profile during production of the facade profile, preferably by welding. In this way, no components or the like that have to be handled separately are necessary.
  • the basic idea of the publication EP 0 955 420 B1 is therefore to use a material for the screw channel that is softer than the materials usually used for the facade profiles.
  • the basic profile is preferably a hollow profile closed on the longitudinal sides, which can be formed in one operation from a flat sheet metal, with the two sides of the metal sheet forming the basic profile colliding and merging into the screw channel lying outside the basic profile, with the transition between the basic profile and the screw channel there is an area where two sheet metal surfaces meet directly, preferably run parallel for a distance, form the bottom of the groove of the screw channel at the end and then diverge towards the end and the U-shaped or trough-shaped screw channel consists of adjacent, but spaced and in particular single-layer surfaces form.
  • the ends of the metal sheet or the cut edges of the metal sheet, which then form the ends are therefore spaced apart and are therefore connected directly to one another at least continuously over the entire length of the profile.
  • individual connecting bridges for stabilizing the profile can lie within the scope of the invention.
  • the fastening elements for guiding an inner seal are arranged at a predetermined, fixed distance from one another or on both sides of the screw channel at a predetermined, fixed distance from a lateral outer contour of the support profile.
  • fastening elements are advantageously designed as fastening recesses and/or fastening projections.
  • connection between the two sheet metal sides forming the screw channel is particularly advantageously designed as a welded connection. Even more advantageously, the welded connection in the groove base is implemented at points, continuously or in sections.
  • this connection can also be designed as an adhesive connection or by form-fitting deformation of partial areas of the sheet metal in the area between the base profile and the groove base.
  • the connection in the area of the groove base can have at least one sheet metal tab that is guided through two sheet metal layers and bent over to produce a form-fitting connection.
  • One embodiment provides that the guide of the inner seal is arranged at a fixed distance from the central axis of the support profile or at a fixed distance from the lateral outer contour of the support profile.
  • the inner seal is preferably designed in one piece.
  • the inner seal is preferably designed as an inner sealing strip which extends over the screw channel.
  • the inner seal is also preferably designed to be divisible or multi-part.
  • the invention also relates to a set of support profiles for a facade, with at least one support profile being designed as described above.
  • the set of support profiles made of steel for a facade with associated inner sealing strips comprises different support profiles according to the invention, each of which has a different face width facing the outside of the facade in the installed position, and different inner sealing strips, each of the different inner sealing strips being matched to one of the different support profiles, and one essentially has the visible width of the support profile corresponding width.
  • the outer seal guide of the inner seal is always in the same place, regardless of the visible width of the support profile. Different visible widths are realized by different widths of the support width of the inner seal.
  • identical sealing concept can also be used for steel or aluminum add-on constructions, as they are already known on the market.
  • the screw channel is not limited by a double wall, as was previously the case when producing one-piece steel profiles with a screw channel.
  • the advantages of the solution are that the wall is more stable than the double wall, is easier to manufacture and, as a result, the overall costs are reduced.
  • the two layers of sheet metal are preferably connected to one another in the transition between the hollow base profile and the screw channel, so that an undesired spreading of the sides of the screw channel, in particular when screwing in a facade screw, is avoided.
  • Such a connection can preferably be achieved by continuous or discontinuous welding, preferably by laser welding.
  • Another way of connecting the two surfaces in the lower area of the screw channel can also be done by punching through both sheets with simultaneous flanging of the punched sheet metal lugs on one side or alternately on both sides, so that both sheet metal sides meet fastened or hooked together.
  • Such a measure can be carried out with the appropriate tool in the context of roll forming or also when folding.
  • a form-fitting deformation such as riveting or screwing between the two sheet metal sides forming the screw channel, in the area between the base profile and the screw channel, can also be produced, for example as part of a roll deformation or edging in the joint area of the sheet metal avoids the two sides of the profile separating, particularly in the area of the screw channel.
  • a one-piece inner sealing strip which is designed in such a way that it extends over the screw channel and preferably rests against it.
  • the inner seal is preferably designed to be divisible, so that it can be easily notched out in the overlapping area between mullions and transoms in order to produce overlapping joints.
  • the screw channel on the support profile is trough-shaped or U-shaped with parallel side walls.
  • the surfaces of the side walls of the screw channel can advantageously have a weld in a curved region of the side walls produced by rolling deformation.
  • the contour of the screw channel on the support profile can project beyond the fastening elements for guiding the inner seal outwards, ie in the direction of the inner seal.
  • the contour of the screw channel can advantageously be designed in such a way that it is open on one side in order to be able to make a screw connection at any point in the screw channel.
  • a particularly favorable way of producing the support profile is to form it from sheet steel by roll forming.
  • All support profiles are formed in one piece from sheet metal, preferably stainless steel sheet metal, with roll forming preferably being used.
  • the two ends of the one-piece profile are formed into a screw channel 10, with a welded connection 11 being present in the groove base 11 of the screw channel, which can be implemented at certain points, continuously or in sections.
  • the embodiments according to figures 1 , 2 and 3 differ in the shape of a fastening element arranged at a fixed distance from the axis of symmetry 12 of the support profile.
  • This fastening element is arranged at a distance X, regardless of the visible width of the support profile, which is between 50 and 80 mm in the present exemplary embodiments.
  • This fastening element can either be a projection 13, as shown in figure 2 is shown, or a recess 14, which, as in the embodiment figure 1 directly on both sides to the shape of the screw channel can connect or, as in the embodiment after figure 3 is designed as a depression 15, which is arranged at a defined distance from the screw channel.
  • Both the fastening projections 13, also called (fastening) approaches, and the depressions 14 and 15 are each located symmetrically to the central axis 12 on both sides of the screw channel.
  • the inner seals 3 are each formed in such a way that they have fastening lugs 16 which engage in the fastening grooves, or have a recess 17 into which a fastening lug 13 in the embodiment according to figure 2 intervenes.
  • the in the Figures 4 to 6 illustrated embodiments have a design of the steel support profile, in which the in the Figures 4 to 6 dimension y shown is kept constant regardless of the face width of the support profile.
  • the seal guide has a constant dimension based on the outer contour of the support profile.
  • the seal can be guided in the form of depressions 14, 15 designed symmetrically to the central axis 12, or alternatively fastening projections 13 according to the embodiment figure 5 be designed.
  • the distance y is 10.5 mm, but this only represents an exemplary embodiment.
  • the distances x and y in the Figures 1 to 6 can of course deviate from the specified values.
  • FIG. 7 to 11 illustrated embodiments show the other elements in section through a facade construction.
  • These are an insulating glass unit 6 as Example of filling elements that can also be designed in a different way, a dam body 5 in the glazing rebate area, which is dimensioned such that it touches the one-piece inner sealing strip 3 and extends to a pressure profile 7 on the outside of the facade.
  • the facade screw is denoted by the reference number 8 and is covered by a cover profile 9 on the outside of the facade.
  • All of the illustrated embodiments have in common that the guide of the inner seal is arranged either at a fixed distance x from the central axis 12 of the support profile or at a fixed distance y from the lateral outer contour of the support profile.
  • These inner sealing strips can also be used with other facade types of a facade system or facade attachment system, for example with different wood-aluminium facades or steel-aluminium facades, which can also be offered in different face widths.
