Definitions

  • the invention relates to a cassette-shaped wall panel made of sheet steel for a curtain wall on a building, which can be fixed together with other similar wall panels by means of rear fastening means on a substructure held on a wall of the building.
  • Cassette-shaped wall panels and curtain walls on buildings made with them have been known in practice for several decades and have also proven themselves. They are made from generally rectangular, flat blanks of aluminum sheet with rectangular notches at the corners. The edges of the cassette-shaped wall panel are produced by bending the edge areas of the blanks in the width of the notches on bending machines. The resulting corners are single-ply due to the notches, but have cut edges that extend to the bending edges and thus practically to the visible surface of the wall panel. The desired inherent and torsional stiffness of such wall panels can be adjusted via the sheet thickness.
  • Sheet steel curtain walls have been known for decades, but they are regularly out composed of large-format longitudinally profiled sheets, which are protected against corrosion by a coating on their surface, in particular a zinc layer. With such large-format panels, the problem of corrosion at the few cut edges can still be tolerated or controlled by suitable measures. In the case of galvanized steel sheets, there is a certain protection against corrosion due to the so-called long-distance protection effect of the zinc. On the other hand, curtain walls made of cassette-shaped wall panels made of sheet steel based on the model of cassette-shaped wall panels made of aluminum sheet appear unsuitable because of the many cut edges that practically reach to the visible side of the wall panel. If one tried to protect the cut edges against corrosion by means of suitable measures, this would increase the manufacturing costs compared to aluminum wall panels in such a way that they would no longer be competitive. Another negative aspect is the comparatively high specific weight of sheet steel.
  • the invention has for its object to provide a cassette-shaped wall panel for a curtain wall on a building that the highest demands Dimensional accuracy and surface quality on the visible side are sufficient in the long term.
  • the latter includes that there must be no corrosion problems on the visible side.
  • the wall panel that meets these requirements should not be more expensive in terms of production costs than a conventional wall panel made of aluminum sheet.
  • the wall panel which is formed from a flat sheet steel blank using the external high-pressure forming process, meets the highest standards of dimensional accuracy because its shape is not created by bending the edges, but by external high-pressure forming. That is why curtain walls with such a precise joint pattern can also be made from such wall panels. Since the shaping is carried out by external high pressure forming, it is ensured that the later visible side is treated extremely gently up to the area of the bending edges and corners during the forming process. In addition, there are no open edges at the corners that would be susceptible to corrosion. Open, corrosion-prone cut edges are only in the rear area, which is hidden from the viewer. If a remote protection effect of the usually provided Zinc coating is not sufficient for corrosion protection, but the cutting edge can also be dip-coated.
  • the closed corners of the cassette contribute to the wall panels having a very high degree of inherent and torsional rigidity.
  • a wall panel made of aluminum sheet with comparable inherent rigidity should have a sheet thickness that is three times thicker.
  • a wall panel made of sheet steel does not have to be heavier than a wall panel made of aluminum.
  • the wall panel according to the invention is therefore a serious competitor to the wall panel made of aluminum, which has previously been predominantly used in practice.
  • the wall panel according to the invention made of sheet steel has a significantly higher surface quality. It is even possible to give the visible side a desired structure by using an appropriate structure for the stamp used in external high pressure forming.
  • At least two opposing shelves have outward-facing flanges on their edges facing away from the bending edges. These flanges can primarily serve as parts of the attachment to the substructure.
  • the shelves can also have hangers as fastening means. They are then preferably designed as shaped cutouts in the shelves for suspension bolts or clasps of the substructure.
  • the invention further relates to a curtain wall made of wall panels of the type described. In the case of a curtain wall, the wall panels are fastened to the substructure with overlapping flanges and with the formation of joints. At the intersection of joints of adjacent wall panels, an intersection element covering the intersection area, for example an injection molded or otherwise shaped part, can be used. The crossing element is attached to the substructure and / or the wall panels. Notches can be provided here so that the material of the flanges does not become too bulky in the crossing area.
  • External high-pressure forming is a technique for producing shells that has been known for decades (DE 12 40 801, EP 1 063 028 B1), but the practical development of cassette-shaped wall panels is suitable for Aluminum has been practiced for decades, ignoring this technology, although attempts have long been made to bring a competitor steel sheet product to the tried and tested cassette-shaped aluminum wall panels.
  • the use of the known method for the production of cassette-shaped wall panels made of sheet steel not only leads to very dimensionally accurate wall panels but also, because of the comparatively high shelves, to dimensionally stable and torsionally rigid wall panels, as otherwise can be made from sheet steel and certainly not from aluminum.
  • the side with the later visible side is already treated gently by exposure to the active medium, it can be further protected by covering it with a protective layer during high-pressure forming.
  • the flange-like strip adjoining the shelves is cut, punched and / or bent up. Then also shaped cuts can be made as hangers.
  • Fig. 2 is a cassette-shaped wall panel
  • Fig. 3 shows the curtain wall of FIG. 1 in
  • FIG. 4 shows the curtain wall according to FIG. 1 in vertical section along line B-B of FIG. 1,
  • FIG. 5 is a detail of the facade of FIG. 1 in an enlarged detail in supervision
  • Fig. 6 shows a device for external high pressure forming in a schematic representation during the stretching of a blank from sheet steel
  • FIG. 7 shows the device according to FIG. 6 in a schematic representation during the high pressure forming of the sheet metal blank to form a cassette-shaped wall panel
  • Fig. 8 is a wall panel in perspective in the cutout in the corner area.
  • the curtain facade shown in FIG. 1 in detail and in view consists of a large number of identical and uniformly shaped cassette-shaped wall panels 1 made of surface-finished steel sheet and a substructure that supports the wall panels 1.
  • the substructure is attached to a wall of a building, not shown. It is not absolutely necessary within the scope of the invention that all wall panels 1 have the same format. Instead of rectangular wall panels 1 shown in the drawing, square or other polygonal wall panels can also be used.
  • a closed curtain wall with dimensionally accurate narrow joints can also be made from hexagonal or octagonal wall panels.
  • Width 200 to 2000 mm
  • each wall panel is cassette-shaped. It arises from the external high pressure forming of a flat sheet metal blank. After the external high-pressure forming, it has a central, planed or structured area 3 with adjoining angled shelves 4, 5, 6, 7. The opposite shelves 5, 7 have a greater height than the shelves 4,6, which, however, carry flanges 8, 9 which are angled outwards.
  • the edges between the central area 3 and the rims 4,5,6,7 are slightly rounded.
  • the seamless corners formed between the shelves 4,5,6,7 are also rounded and have a much larger radius of curvature than the rounded edges. The proportions of the rounded edges and corners can be seen from the scale representation of FIG.
  • the flanges 8, 9 of adjacent wall panels 1 overlap one another.
  • the Wall panels 1 are arranged to form narrow joints from one another.
  • a cross element 23, for example a cast or otherwise shaped element 23, is fastened to each crossing point, which is fastened to one another with screws or rivets 24, 25 overlapping flanges 8.9 is attached.
  • the position of the cross elements 23 is raised, flush or set back relative to the visible side.
  • a wall panel 1 is produced by external high-pressure forming.
  • a flat blank made of sheet steel with a surface finish at least on its later visible side is brought into a forming machine and is clamped on its circumferential edge in a liquid-tight manner at least on the underside.
  • an active medium is introduced into the lower space, which pre-stretches the area of the blank that is not clamped.
  • an upper, shaping punch is moved against the sheet metal blank, the counter pressure being maintained by the active medium acting on the other side.
  • the shape of the stamp determines the shape of the workpiece. With a corresponding surface structuring of the stamp, various structuring can also be produced on the visible side, which then push through the sheet. The result is a cassette-shaped part that is only on its edge needs to be trimmed and folded in order to maintain the shape of the wall panels 1 according to FIG. 2.
