Definitions

  • the invention relates to a lightweight metal plate in Shape of a cusp plate made of a compression molded Bump plate and one on the end faces of the bump flat sheet metal bonded.
  • Lightweight metal panels come in different shapes, especially as hollow shelves and as bump panels known.
  • Hollow compartment panels and cusp panels consist of outer cover plates and arranged in between Spacers of various types. In such Depending on the load, lightweight panels work one way outer cover plate as tension belt and the other as Compression chord.
  • Such lightweight boards have compared to massive plates with the same basis weight a higher Flexural and buckling stiffness. They are therefore considered load-bearing components for walkable floor slabs or Road slabs, but also used for walls.
  • Known hollow shelves made of aluminum or steel consist of outer cover plates and arranged in between as spacers, only in one Continuous webs running in the direction of the Cover plates are firmly connected.
  • aluminum cover plates and webs are in one piece extruded.
  • With a hollow shelf made of steel the webs of trapezoidal sheets folded in a zigzag shape formed, which are welded to the cover plates.
  • bump plates made of steel or aluminum are characterized by that they consist exclusively of two interconnected Cover plates exist, of which at least one plate as Bump plate is formed.
  • This bump sheet can be on the hump end faces of a similar hump plate or connected with a flat sheet.
  • the advantage of such a bump plate is that it has the same buckling stiffness in all directions.
  • the ratio of weight to is unfavorable Bending stiffness or buckling stiffness (see also DE 19503166A).
  • the invention has for its object a Lightweight metal plate in the form of a cusp plate create a good with a low basis weight Flexural rigidity in the x and y direction of the plate plane and has good buckling stiffness.
  • the material-specific advantages of aluminum and steel exploited to get a lightweight board compared to their basis weight conventional lightweight panels only made of steel or only made of aluminum has improved bending stiffness and Has stiffness.
  • the lightweight board is loaded from the side of the flat sheet is for resistance against buckling the moment of inertia of the Flat sheet decisive. The moment of inertia is over the higher, the thicker the flat sheet is dimensioned.
  • the use of a flat sheet made of aluminum advantageous because it has the same basis weight much thicker than a flat sheet made of steel can be dimensioned.
  • the Bump distance in the lightweight panels according to the invention compared to cusp plates exclusively made of steel be about 6 times bigger, forming an overall larger area moment of inertia to stiffen the Tension belt leads.
  • less material is made from the Sheet steel pressed out to form the humps and the Number and area of the necessary connection points will be kept comparatively low. Because of this minor Area share of the cusps in the total area of the Bump plate is the tensile strength of the Bump plates are not compared to flat plates significantly impaired.
  • the steel hump plate is subjected to tensile stress and steel a lot compared to aluminum has a higher modulus of elasticity is also a higher one Buckling stiffness of the lightweight board according to the invention in Compared to an existing one only as aluminum Lightweight board guaranteed. Because of the good Deformability and the high modulus of elasticity of steel also pressing the humps is no problem. Through the special combination of different materials Aluminum and steel on the hump end faces is also ensures that without affecting the Material properties of the flat sheet and the bump sheet stay stiff and firmly connected in the long run.
  • connection between steel and Aluminum can continue in various ways be improved. According to an embodiment of the invention it is envisaged that the steel hump plate on its Connection side is galvanized. This also makes the prevents so-called crevice corrosion. Alternatively or in addition, the connection can also be form-fitting. In particular, the positive connection of the connection of in Engaging parallel grooves and ribs of the Sheets are formed.
  • the bumps a trapezoidal cross section and are longer than wide.
  • the lightweight board can be the cavity between the Sheets filled with a dimensionally stable filling material his. These are preferably foam materials or Hollow body with plastic binding.
  • a steel sheet thickness greater than 1.3 / 3 d Al can also be used to produce fanning out of rectangular frame constructions. In this case, in the case of elongated cusps, the longitudinal axis of the cusps should run in the direction of the smaller frame distance.
  • the ratio of the connected area (cusp face) to the total area should be 5 - 13%.
  • the mutual distance a of the humps at half height should be 8 - 12 times the distance of the sheets h.
  • the invention also relates to a method for producing a lightweight board according to claim 1.
  • a method for producing a lightweight board according to claim 1 is in accordance with the invention characterized in that the steel Bump plate and / or aluminum Flat sheet limited locally to that on the Cusp face surfaces to be joined surface area activated by heating with laser radiation, but not are melted and in this state both sheets be connected to each other by pressure.
  • the Connection under pressure is preferably made by Roll joining, as is known per se (DE 19 502 140 C1), but in particular the subject of an older German Patent application is (DE 19640612C1).
  • a Form-locking connection through plastic deformation of the Flat sheets made of aluminum can be achieved.
  • the Flat aluminum sheet in the cusp ribs to be embossed which is in the flat sheet Push.
  • the lightweight construction panel shown in FIG. 1 consists of a steel hump plate 1 with a multiplicity of elongated humps 2, oval in plan and trapezoidal in cross section, and a flat plate 3 made of aluminum.
  • the hump plate 1 is preferably galvanized on its side facing the flat plate 3.
  • the positive connection is brought about by the intermeshing of ribs and grooves of the hump end faces and the flat plate 3, the outer side of the flat plate 3 facing away from the hump plate 1 being flat.
  • the cusp ends have a length D x and a width D y .
  • the distances between the centers of adjacent cusps in the direction of the x-axis are l x and in the direction of the y-axis l y .
  • the distance between adjacent bumps 2 at half the bump height in the direction of the y-axis is a.
  • the bump sheet 1 has a thickness d St
  • the flat sheet 3 has a thickness d Al .
  • the cavity height between the two sheets 1.3 is h.
  • the flat sheet 3 made of aluminum is considerably thicker than the bump sheet 1 made of steel in order to be able to cope with the operational stresses.
  • Such a lightweight board is usually loaded so that the thicker flat sheet 3 made of aluminum acts as a compression belt and the thinner hump sheet 1 made of steel acts as a tension belt.
  • the lightweight board is manufactured in such a way that the molded bump plate 1 of a rolling stage is supplied, as shown in Figures 2 and 3.
  • the surfaces of the flat end faces of the bumps 2 with a laser beam 5 activated. It must not melt or even to evaporation on the surface, such as the Zinc coating, come.
  • Lasers can be gas lasers or solid state lasers, because of that high power, especially diode lasers, used.
