Definitions

  • the invention relates to a reinforced by an axially inserted metal profile plastic hollow profile of the type mentioned in the preamble of claims 1 and 2 and a frame made from such a hollow profile, in particular window or door frame.
  • Hollow plastic profiles of the type in question are used in particular in the field of building construction for the production of frame elements, especially for window frames including window sashes and door frames including frame sashes for folded doors.
  • Such hollow plastic profiles are economically notable for their low cost and technically for good thermal characteristics, in particular due to their low thermal conductivity and weather resistance superior to that of other materials resistance and corrosion resistance.
  • hollow plastic profiles are disadvantageous in terms of their low bending stiffness and torsional stiffness, even when they are stiffened by inserted metal profiles. This applies in particular to the multi-chamber profiles in use today, in which the outer chambers of the hollow plastic profile serve for thermal insulation and as a result the volume and effectiveness of the overall assembly, which is intended for the insertion of the stiffening iron, loses. This forces an improvement in the effectiveness of the stiffening of the combination profile which can be achieved by drawing in the metal profile.
  • the effectiveness of the stiffening is basically two. Factors essentially determined, namely by the rigidity of the metal profile drawn into the chamber of the plastic hollow profile to be stiffened and by an improved frictional connection between the metal profile and the plastic hollow profile.
  • the rigidity of the metal profile reinforcing the plastic hollow profile can be improved by appropriate shaping, for example by pulling in stiffening beads (see DE 80 30 522 U 1).
  • the frictional connection between the stiffening metal profile can be improved in that the metal profile and the profile of the chamber to be reinforced in the plastic hollow profile, into which the metal profile is inserted, in it rer dimensioning are coordinated so that a frictional connection is made between the metal profile and the chamber to form an all-round fit.
  • This frictional engagement can be improved in that the metal profile is slightly resiliently biased against the inner wall of the chamber of the hollow plastic profile to be reinforced.
  • the procedure is such that with a coaxial position of the metal profile in the hollow plastic profile, the outer wall of the metal profile with a nominal size all around to the inner wall of the chamber of the hollow plastic profile, also based on the nominal size, has an air gap of 1.5 to 2 mm and so dimensioned metal profile on one of its main surfaces from outside through the plastic hollow profile with self-tapping screws the plastic hollow profile or the inner wall of the reinforced chamber is screwed.
  • these non-positive screws are shown in the axial direction at intervals of approximately 30 to 50 cm.
  • the hollow plastic profile is bent until a three-point support on the hollow plastic profile is reached, namely on the load side in the center and on the side opposite the load, i.e. on the two opposite outer end faces . It has been shown in practice that these acting forces are so great that the frictional connection caused by the screwing on the outer edges is largely eliminated by creeping or cold flow of the plastic.
  • the bending deformations that occur in practice as a result of these bending processes due to inserted metal profiles of reinforced plastic hollow profiles may well be in the range of around 1 mm and thus give rise to disturbances.
  • the invention has for its object to improve a reinforced by an axially inserted metal profile cross-sectionally closed hollow plastic profile of the type described in that the conclusion between the inserted metal profile and the hollow plastic profile to improve the bending stiffness of the reinforced composite profile in is improved in a way that can be realized in the context of the practical industrial manufacture of such composite profiles.
  • a window sash with a screwed reinforcing metal profile taken at random from the current production, with a screw spacing of 300 mm and one Using a hydraulic ram and a support plate simulated wind pressure of 0.9 kN / m 2, a maximum external lifting of the inner wall of the reinforced chamber of the hollow plastic profile from the outer wall surface of the reinforcing metal profile of 0.99 mm, made possible by cold flow of the plastic (PVC), was measured. Under identical test conditions, an identical hollow plastic profile, into which a reinforcing iron, precisely manufactured with an oversize in the micrometer range, is hammered in, forming a profile separation gap with a width of only 0.53 mm.
  • a saddled reinforcing metal profile according to the invention which has been manufactured in such a way that it has the same air as the profile taken out of production, namely 1.6 mm all around, based on the coaxial position, shows under the same test conditions and down to the saddle rail identical molded and made of the same material hollow plastic profile also a profile gap of just under 0.55 mm.
  • the saddled profile can be easily inserted into the chamber of the hollow plastic profile to be reinforced even under industrial production conditions.
  • tolerance-related dimensional deviations can be compensated for in a resilient manner without a noticeable increase in the insertion forces.
  • the nominal dimension of the Profile handle that is, the dimensions of the Axialsteges and Axialschienen
  • low undersize is also at greater tolerance-related deviations of I always striche conclusive form composite ensures that the metal profile can no longer be inserted for actual dimensions in the range of the lower tolerance range limit.
  • the axial rails are preferably designed with axially extending sliding ribs, the height of which is preferably only a fraction of a millimeter.
  • Such guide ribs can also be provided on the inner wall of the chamber of the hollow plastic profile to be reinforced, but naturally have a profile height there which can be in the millimeter range.
  • slide ribs are optionally also formed, however, with a profile height in the range of a fraction of a millimeter also on the inner wall.
  • this metal profile can be designed in a manner known per se and customary with its outer contour complementary to the inner contour of the chamber of the hollow plastic profile to be reinforced, can resiliently abut the inner walls of the reinforced chamber of the hollow plastic profile or can finally with stiffening and / or be resilient axial beads.
  • a major advantage of the saddling of the metal profile is, however, that the metal profile saddled in this way no longer has to rest on all walls of the chamber to be reinforced in order to bring about a satisfactory reinforcement of the hollow plastic profile.
  • This refolding is preferably carried out in such a way that the two walls of the double walls produced by bending back the profiled sheet do not touch each other, but maintain a distance of the order of about 1 to 10 material thicknesses, so that despite the considerable stiffening in the wall plane for the overall profile transverse to it Wall level a certain spring elasticity can be maintained in a very desirable manner.
  • the saddling of the metal profile on one or more axial webs within a chamber of the hollow plastic profile can be realized in several ways.
  • a single T-shaped axial web, which extends through the axial slot of the metal profile so to speak, is sufficient for the form-fitting fixing of the areas of the metal profile lying on both sides of the axial slot against the corresponding inner wall of the chamber.
  • a largely flat surface Contact of the metal profile with two preferably adjacent and in particular corner internal walls of the chamber are sufficient to sufficiently stabilize the reinforced plastic hollow profile as a whole.
  • the axial web of the hollow plastic profile can in principle be provided on any inner wall of the corresponding chamber of the hollow plastic profile, it is possible to make its one-piece connection to the inner wall of the chamber dependent on the intended use and the expected load characteristics. If, for example, the load that is to be taken into account decisively through a laminated glass system is to be taken into account, it is advantageous to provide the axial web on the inner wall of the corresponding chamber of the hollow plastic profile that is approximately perpendicular to the action of force.
  • Stabilizing the inserted metal profile with respect to two inner walls has the advantage on the one hand of transferring and equalizing the decisive forces acting on the hollow plastic profile and on the other hand brings a considerable reduction in material and costs compared to a metal profile that follows the complete inner contour of a chamber.
  • the aim is to have a multiple positive connection in the area of the axial web, e.g. if possible to achieve a triple form fit.
  • a stiffening bead of the normally double-walled metal profile is therefore advantageously shaped such that it reaches at least one positive engagement in the groove of the T-shaped axial web.
  • the other positive connections between the axial web or the inner wall of the chamber and the metal hollow profile are preferably designed so that they result in a different direction of force connection than already existing positive connections.
  • Another type of interlocking connection between a reinforcing metal profile and the inner wall of a chamber is produced, for example, by one or more axial webs on an inner wall of the chamber, one or more preferably arranged symmetrically axial webs on the diametrically opposite inner wall of the chamber.
  • the metal profile should be essentially with appropriate play follow the inner contour of the chamber towards the inner wall.
  • the axial slit of the metal profile is exposed here, which means that it is not engaged by the axial webs. Rather, the approximately complementary bead contour of the metal profile in the region of the axial webs experiences a spring-like contact through the legs of the metal profile that are movable relative to one another and adjoin the axial slot of the metal profile.
  • the profiles of the type described here are preferably used for the construction of windows and doors, both of sticks and of sashes and frames of different types.
  • the reinforced composite profile 1 shown schematically in cross section in FIG. 1 consists of a hollow plastic profile 2, in which the reinforcement is brought about by an axially inserted metal profile 3.
  • the chamber 4, into which the metal profile 3 is inserted, is surrounded by further outer chambers 5 which serve for heat insulation and other purposes which are not of interest here in the given context.
  • the chamber 4 of the hollow plastic profile 2 to be reinforced has, apart from a recess 6 of no interest here, essentially a rectangular cross section.
  • the metal profile 3 is designed with its outer contour complementary to three of the four inner wall surfaces of the chamber 4, namely in the illustration of FIG. 1 complementary to the upper inner wall 7, the left inner wall 8 and the right inner wall 9 of the chamber 4.
  • the metal profile 3 essentially the shape of a downwardly open U-profile, which stands with the edges of its side legs on the lower fourth inner wall 10 of the chamber 4 of the hollow plastic profile 2.
  • This metal profile 3, which is essentially designed as a U-profile, is formed as a self-contained hollow chamber profile by bending the profile sheet back to form double-wall structures 11, 12 and 13, 14.
  • the lower rebend regions 15, 16 of the metal profile 3 are at least substantially arcuate in cross section, so that a skid is formed which, when the metal profile 3 is inserted into a chamber 4 with an actual undersize, the metal profile 3 on the lower inner wall surface 10 of the chamber 4 there is hardly any frictional resistance to the insertion.
  • the hollow-chamber metal profile 3 has an axial slot 17 on its upper side which is completely continuous which engages positively through an axial web 18 which is integrally formed on the hollow plastic profile 2 on the upper inner wall 7 of the chamber 4.
  • the form-fittingly engaging in the slot 17 of the metal profile 3 axial web 18 has a likewise axially continuous groove 19 which is dimensioned such that the axial web is hardly noticeably resiliently deformable transversely.
  • At least essentially T-shaped axial rails 20, 21 are integrally formed, which engage the metal profile 3 on both sides of the axial slot 17 in the metal profile 3 in a form-fitting manner.
  • the axial rails 20, 21 are at least so wide in the transverse direction that they ensure a good and reliable positive connection to the metal profile 3 that is engaged behind.
  • the metal profile 3 also lies flush against the upper inner wall 7 of the chamber 4 of the hollow plastic profile 2 in these recessed areas 22, 23.
  • the flange-like axial rails 20, 21 each have an axial rib 24, 25 on their outer edges, which are only a fraction of a millimeter high, project in the direction of the engaging portions 22, 23 of the metal profile 3 and primarily serve the purpose of axially inserting the To reduce metal profile 3 in the chamber 4 occurring frictional resistances.
  • Corresponding axial ribs are preferably also formed on the opposite inner wall surface 7 of the chamber 4 in a manner not shown in FIG. 1.
  • the metal profile 3 also has a non-flattened stiffening bead 26 which runs parallel to the longitudinal axis of the metal profile and extends over the entire axial length of the metal profile 3.
  • the hollow plastic profile 2 is made of PVC, while the metal profile 3 is made of galvanized sheet steel.
  • the plastic hollow profile according to FIG. 2 corresponds in fragments to the plastic hollow profile according to FIG. 1.
  • a metal profile 3 changed from FIG. 1 is inserted into the chamber 4, which provides a further, and therefore triple, form fit between the axial web 18 and the metal profile 3 allowed.
  • a stiffening bead 30 is provided in the inner profile wall of the double wall structure 13 'and 14', but it projects into the groove 19 formed in the axial web 18.
  • the stiffening bead 30 rests on the left U-leg of the groove 19.
  • the left-hand positive connection in the groove 19 therefore makes it possible, in addition to the positive connections already existing between the axial rails 20 and 21 and the areas 22 and 23, to better absorb horizontally directed forces and the resulting bending stresses of the plastic profile.
  • This further positive locking is therefore primarily perpendicular to that mainly for the equalization of vertically acting force components provided form-fitting connection aligned at the areas 22 and 23.
  • an axial web 35 or 34 is formed both on an upper inner wall 31 and on a diametrically opposite lower inner wall 32. These axial webs 35 and 34 are at a relatively small distance from the vertical inner wall 33, an undercut 36 being formed in this intermediate space.
  • the metal profile 3 used in this case has a single-walled hollow profile with an axial slot 17 ', which is provided in the example on the right side of the chamber and runs, so to speak, into the plane of the drawing.
  • the legs 47 and 48 of the metal profile 3 adjoining the axial slot 17 can therefore perform a type of spring movement in the direction of the width of the axial section 17 '.
  • the metal profile has rounded, U-shaped beads 38. In the example, these beads 38 projecting further into the interior of the chamber 4 form, with the axial webs 34 and 35, two form-fitting engagement areas between the hollow plastic profile and the metal profile. In addition to this, there is a further positive connection in the area of the undercut 36, which adjoins the corresponding axial web 34 or 35, and the approximately vertical wall area of the metal profile 3.
  • the metal profile 3 is kept with a slight undersize, if possible, so that a force-fitting narrowing of the axial slot 17 'with subsequent spreading movement of the legs 47 and 48 is sufficient for inserting the entire metal profile 3.
  • both vertical and horizontal forces are equalized by the reinforcing metal profile to such an extent that the plastic hollow profile can be lifted off the metal profile due to deflections only in the aforementioned permissible relation range.
