Definitions

  • the invention relates to a metal profile for reinforcing plastic hollow profiles, plastic hollow profiles reinforced by such metal profiles and frames, in particular window frames and door frames, which are at least partially made from such reinforced plastic hollow profiles.
  • Hollow plastic profiles are used in particular in the field of building construction for the production of frame elements, in particular window frames and door frames.
  • Such plastic Hollow profiles are characterized in economic terms by being particularly inexpensive and in technical terms by good thermal characteristics, especially by low thermal conductivity, and by weathering and corrosion resistance superior to other materials.
  • plastic hollow profiles are disadvantageous in terms of their low bending rigidity and torsional rigidity.
  • the invention has for its object to provide a metal profile for the more effective reinforcement of hollow plastic profiles, that is, a metal profile that has improved bending stiffness and torsional rigidity and transfers this strength improved to the hollow plastic profile, one by one to insert inserted metal profile reinforced plastic hollow profile with improved stiffness characteristics and finally to create a frame element which, by using the stiffened plastic hollow profiles with one-sided suspension, has an improved torsional stiffness transversely to the frame plane and an improved bending stiffness in the plane of the frame plane.
  • the invention provides a metal profile which has the features mentioned in the characterizing part of patent claim 1.
  • the plastic hollow profile reinforced by such an inserted metal profile is characterized according to the invention in that the plastic hollow profile rests on the inside with at least one smooth, flat and unprofiled inner wall surface on at least one corrugated outer wall surface of the inserted metal profile.
  • the frame, in particular window frame or door frame, of the invention is characterized in that it contains a metal profile which reinforces the hollow plastic profile and in particular contains a reinforced hollow plastic profile with the features described above.
  • the metal profile can contain the stiffening bead running parallel to the longitudinal axis either only in one longitudinal wall of the profile or in several longitudinal walls or finally also in all longitudinal walls of the profile.
  • each longitudinal wall that is, based on the cross section of the profile, each leg of the profile, can have one or more such stiffening beads. If only one stiffening bead is formed in a wall, this stiffening bead does not have to be arranged in the middle of the height or width of the longitudinal wall, but can, for example, also run relatively close to an edge which is formed by this longitudinal wall.
  • stiffening beads running parallel to one another and parallel to the longitudinal axis of the metal profile are preferably designed such that they have the same cross-section to their longitudinal direction result in moderate corrugation of the longitudinal wall of the metal profile.
  • This corrugation can either extend over the entire width of the longitudinal wall or alternatively can remain limited to a partial region of such a longitudinal wall, so that the respective longitudinal wall has plane, strip-shaped wall regions in addition to a corrugated wall region extending over the entire axial length of the metal profile.
  • An improvement in the bending stiffness of the metal profile can already be achieved in the formation of only relatively flat beads.
  • the worst case is that only one flat bead is arranged in the middle of the longitudinal wall, based on its width, in a longitudinal wall of the metal profile.
  • An improvement in the bending stiffness that can be achieved with such a flat bead is achieved in that the flat bead is moved out of the center of the wall surface towards an edge.
  • the flat corrugation does little to improve the bending stiffness of the metal profile and practically nothing to improve the torsional stiffness of the metal profile. Much better results are achieved with relatively deep beads.
  • the metal profile therefore preferably has a clear depth of the stiffening bead or stiffening beads which is at least four times, preferably at least six times the material thickness of the metal profile.
  • “Clear depth” is understood to mean the distance from the outer surface of the wall of the metal profile adjacent to the bead to the lowest point of the base of the bead.
  • Such deep stiffening beads have significant advantages over the flat stiffening beads.
  • the deep corrugations result in a better bending stiffness and in particular a torsional stiffness of the metal profile. They effect for the metal profile a certain elasticity perpendicular to the longitudinal direction of the stiffening beads, whereby a particularly good connection of the metal profile to the hollow plastic profile is obtained. As a result, it is possible in particular to work with thinner material thicknesses than with a metal profile with a flat bead.
  • the deep stiffening beads are preferably designed such that they have a clear opening width to the outside, ie a clear distance from an outer bead edge to the opposite outer bead edge, which is at least equal to the clear depth of the stiffening bead. Furthermore, at least two of the deep stiffening beads are preferably formed side by side in at least one longitudinal wall of the metal profile in such a way that the two deep stiffening beads running side by side result in a continuous corrugation of the longitudinal wall.
  • the hollow plastic profiles reinforced with such metal profiles have an inner profile which is closed in cross-section and which has at least one completely flat and level non-profiled inner wall surface which bears against at least one corrugated wall of the metal profile, preferably against the corrugated metal profile wall provided with a deep double bead.
  • the hollow plastic profile, into which the metal profile provided with the deep beads is inserted or knocked in does not engage in any way in these beads, at least in the area in which the deep beads of the metal profile are formed.
  • This mechanical prestressing of the deeply corrugated metal profile in the hollow plastic profile can be brought about in that the metal profile is designed with a slight oversize in the relaxed state and is hammered into the hollow profile with little resilient deformation and / or that a cold metal profile is inserted into a uniformly heated hollow plastic profile and the result is obtained Insert structure is then cooled to room temperature. As a result, the plastic hollow profile is thermally shrunk onto the metal profile. In any case, a composite profile is achieved in this way, which cannot be achieved by positive engagement between a reinforcing metal profile and a complementarily hollow plastic profile.
  • This bond can be improved by exciting and fixing, in particular self-tapping metal screws, which are screwed from the outside through the plastic hollow profile into at least one wall of at least one stiffening bead.
  • the axis of the screw can run both in the direction of the depth of the bead, so that the screw passes through the sole of the bead, and also lie perpendicular to this direction, so that the screw passes through one or both side walls of the bead.
  • Frames made from such reinforced plastic hollow profiles for building construction are characterized by improved rigidity both in the case of forces acting transversely to the frame surface, for example wind forces, and in the case of forces which act in the plane of the frame, for example with regard to forces caused by the weight of the frame with one-sided suspension.
  • the metal profile which is open in cross section, essentially has the shape of a C profile.
  • the stiffening beads 4, 5 are not arranged in the middle of the longitudinal walls 2, 3, but in the region of the profile edges 6, 7, which the longitudinal surfaces 2 and 3 with the two longitudinal surfaces connecting longitudinal surface 8 form.
  • Two deep stiffening beads 9 and 10 are formed in the longitudinal surface 8, the depth of which is seven times the material thickness, that is to say the wall thickness of the metal profile.
  • the deep stiffening beads 9 and 10 are arranged in relation to one another in such a way that they form a uniform corrugation of the longitudinal surface 8.
  • the inner legs 11 and 12 of the metal profile 1 do not run at right angles to the longitudinal walls 2 and 3, but each enclose an angle of somewhat greater than 90 ° with these longitudinal walls. When such a metal profile is hammered into a rectangular plastic hollow profile, these side legs are slightly resiliently deformed, so that the metal profile sits in the plastic hollow profile under prestress. It should be noted that the illustration shown in FIG. 1 has not been exaggerated to scale, but rather for the sake of better visibility.
  • a second embodiment of a metal profile 1 ' is shown in FIG. 2, namely inserted into a hollow plastic profile 13.
  • the hollow plastic profile 13 for example a window frame profile, is only indicated in the cutout, since the overall design of such a hollow plastic profile is not the subject of the present application and Expert is familiar anyway.
  • the hollow plastic profile 13 has a cavity 14 which is enclosed by four perfectly flat inner wall surfaces 17 which are at right angles to one another.
  • the hollow profile 13 is thermally shrunk onto the metal profile 1 '.
  • the side legs or longitudinal walls 2 'and 3' of the metal profile 1 ' have no stiffening beads.
  • the inner legs 11 'and 12' of the metal profile 1 ' are arranged exactly at right angles to the longitudinal walls 2' and 3 '.
  • the longitudinal wall 8 'of the metal profile 1' has two deep stiffening beads 9, 10, each of which has a clear depth of approximately eight times the material thickness and a clear opening width of approximately 15 times the material thickness.
  • the beads 9 and 10 open to or on the completely flat inner wall surface 15 of the cavity 14 of the plastic hollow profile 13. No projections are formed on this inner wall surface 15 which engage in the beads 9 or 10.
  • the bond between the metal profile 1 'and the plastic hollow profile 13 is defined by a Metallschrau - be 16 amplifies.
