Definitions

  • the invention relates to a thermally insulated metal profile, preferably for windows, doors or facade elements, with spaced apart profile elements of a frame profile being connected to one another by at least two insulating bars, the insulating bars having two terminal connecting strips for connecting the insulating bar with grooves in the profile elements and at least one profile bar section between have the terminal connection strips, each insulating web having at least two receptacles directed towards the other insulating web and the two insulating webs being positively connected to one another by means of at least two bridge webs which are arranged in the receptacles, as well as bridge webs for use in such a thermally insulated metal profile.
  • Thermally insulated metal profiles especially for windows, doors or facade elements, have been known for a long time in a wide variety of designs.
  • the preferred use of insulating bars made of plastic is, for example, that which goes back to the applicant DE 10 2011 117 170 A1 known.
  • the insulating webs used have a cross-section that is essentially the same over their entire surface. It is also already known to reinforce the insulating webs, especially in the fastening area, in order to ensure a secure hold of the fastening elements used.
  • Insulated window and door profiles made of aluminum usually consist of an inner and outer half-shell made of aluminum, which are connected to each other in a shear-resistant manner (usually, occasionally in case of casement profiles also in a shear-soft manner) using plastic insulating bars.
  • the composite zone is also the most important area for thermal insulation, which means that you actually want to prevent thermal bridges and material accumulations made of poorly insulating materials such as metal.
  • the insulating webs are provided on one side with thin webs or "fins", which protrude vertically from the insulating webs into the interior of the composite profile.
  • this type of construction is disadvantageous with regard to the transport and storage of such insulating bars, as they are difficult to stack and lead to a smaller pallet content.
  • the sometimes relatively long fins are also not contour-stable under pressure when transported on pallets.
  • Such a design also leads to an undesirably high number of items of insulating bars, the base body of which can be identical, but which differ due to different lengths of the fins.
  • a generic thermally insulated metal profile is from the EP 3 447 229 A1 known.
  • two aluminum half-shell elements are connected to one another in a form-fitting manner by means of two insulating webs arranged at the ends.
  • these two insulating bars are connected to each other using two bridge bars.
  • the insulating webs have corresponding receptacles and the bridge webs have corresponding widenings at their ends. The ends of the bridge bars are clipped into the corresponding receptacles of the insulating bars.
  • the clip connection comes loose, for example, if there are dimensional deviations in the mounts (points) in the aluminum half-shells. Or alternatively, in the case of positive and non-positive fit, the insulating bars are deformed so that other recordings (functional areas) of the insulating bars are impaired or no longer function at all.
  • connection is too loose, for example in the case of a vertical coating in which the profile is suspended vertically, the bridge webs would slip out and disrupt or even interrupt the coating process. Furthermore, during the transport or processing of the profiles into windows, doors or facades by sawing, drilling, milling, slipping might also occur, which would also disrupt or interrupt this processing process.
  • the invention is therefore based on the object of achieving an improvement in both the manufacturability and the processability of the thermally insulated metal profiles in question.
  • a thermally insulated metal profile and bridge webs intended for this should be created, which can compensate for the existing and not entirely avoidable tolerances and, on the other hand, the contradictory requirement that a hold is created after the connection has been made, which prevents slipping due to the bridge web's own weight during transport the profiles or their further processing is reliably prevented.
  • This task is achieved in an insulating web with the features of the preamble of claim 1 in that the receptacles on one insulating web are designed as fixed bearings and on the other insulating web as floating bearings. This ensures that tolerances occurring in the manufacturing process can be reliably compensated for without weakening the overall stability of the composite profile.
  • the terminal strips within the fixed bearing have a groove into which an adhesive cord is inserted.
  • profile-side connecting strips of the insulating webs can preferably also have a groove for receiving the adhesive cords.
  • each insulating web has a hollow chamber profile section at the ends of its profile bar section, which is arranged in front of the terminal connection strips and is connected in one piece to them and to the profile bar section.
  • the cross section of such a hollow chamber in the insulating web has the shape of an 'eye' and enables the optimal combination of mechanical properties (stability, rigidity and force introduction) and thermal properties (thermal insulation).
  • each insulating web has a centrally arranged reinforcing section, which is intended to serve in particular to accommodate fastening elements, to simplify the insertion of fastening screws and also to provide better lateral guidance and increased stability.
  • the reinforcing sections are preferably formed in one piece with the insulating webs.
  • the receptacles of the insulating webs are designed as receiving grooves and the bridge webs have terminal strips on their longitudinal edges that correspond to the receiving grooves.
  • An alternative embodiment of the invention provides that the receptacles are designed as terminal strips and that the bridge webs have receiving grooves on their longitudinal edges that correspond to the terminal strips.
  • At least one of the cavities formed by the two profile elements and the insulating webs and bridge webs arranged between them can also be filled with a heat-insulating material.
  • the invention also relates to bridge webs for use in a thermally insulated metal profile described in more detail above, preferably a window, a door or a facade, with two profile elements arranged in parallel and with at least two insulating webs connecting the profile elements, the bridge webs being designed according to the invention as follows:
  • Plastic can be used as the material for the bridge webs, which can also be a glass fiber reinforced plastic (GRP) or a carbon fiber reinforced plastic (KFK).
  • GRP glass fiber reinforced plastic
  • KFK carbon fiber reinforced plastic
  • the bridge web can be covered with a very thin aluminum foil on at least one of its surfaces.
  • the bridge web preferably has roll-formed ends for connection to the insulating webs.
  • the base material aluminum itself ensures a high level of reflection on its surfaces, so that additional foil is not necessary.
  • the terminal strips of the bridge web have elements in the contact area with the receptacles of the insulating webs to increase the frictional resistance in the longitudinal direction of the bridge webs.
  • the ends of the bridge webs inserted into the receptacles of the insulating webs can be "clamped" in their final position, so that the bridge webs are reliably prevented from slipping out.
  • the elements for increasing the frictional resistance are preferably designed as tabs which extend in the longitudinal direction of the bridge webs and can generate the desired frictional resistance by bending accordingly.
  • the elements to increase the frictional resistance may be designed as punctual embossing, particularly in the case of bridge webs made of metal.
  • the number of elements to increase the frictional resistance is variable and can be tailored to the respective area of application. In this way, optimal coordination of the structural parts to be connected to one another can be achieved with little effort.
  • Fig. 1 shows a profile composite combination of a heat-insulated profile 1 known from the prior art, having an inner shell 2 and an outer shell 3 made of an aluminum profile and two insulating webs 4 and 4 ', which connect the two profile elements 2 and 3 by pushing them into one another at a predetermined distance.
  • the two insulating webs 4 and 4 ' are connected to one another via two bridge webs 5 according to the invention.
  • both insulating webs 4 and 4 'each have two receptacles 6 and 6' into which the bridge webs 5 can be inserted.
  • the profile elements 2 and 3 have grooves 2a, 2b and 3a, 3b on their surfaces facing one another.
  • 3a, 3b have corresponding connection strips 7, which widen like a foot towards their end and each have a centrally arranged (unspecified) groove there.
  • Adhesive cords (not shown) can be inserted into the grooves shown to make further assembly easier.
  • the hot melt adhesive used can be activated by heating after being pushed into one another.
  • the aluminum half-shells 2, 3 with the insulating webs 4,4 ' can also be rolled into a composite profile.
  • connection strip 7 is divided into two wall elements 9 and 10 or 9 'and 10', each with reduced wall thickness.
  • the wall elements 9, 10 and 9 ', 10' merge into a straight central profile bar section, which is designated by the reference number 11 for the insulating web 4 and with the reference number 11' for the insulating web 4'.
  • the profile bar section 11 and the hollow chamber sections 9 are aligned and form a common outer plane 12.
  • the profile bar section 11' has an outer plane 12' over its length, which can serve as a stop for further profile elements or functional components .
  • a centering groove 13 extends in the middle to facilitate drilling for fastening the profile 1 to the masonry or for fastening other components such as a lock, striking plate or the like.
  • Fig. 2A shows an embodiment with insulating webs 4a and 4a', the receptacles 6a and 6a' of which are designed as receiving grooves.
  • the insulating webs 4a and 4a' each have a clamping web, which is surrounded by receiving grooves 6a and 6a' on the longitudinal edges of the bridge web 5a.
  • the receptacle 6a forms the fixed bearing on the insulating web 44 through a positive and non-positive connection with the bridge web 5a.
  • the receiving groove 6a' on the opposite side of the bridge web 5a is made deeper and thus forms the desired floating bearing on the insulating web 4a'.
  • both surfaces of the bridge web 5a shown have planking with a thin aluminum foil 14.
  • FIGs 2A and 2B show shots on the insulating webs 4a and 4b, whereby the connection to the bridge webs 5a and 5b in the area of the fixed bearing is made in addition to the positive connection via an adhesive connection with an adhesive cord 15 known for insulating webs.
  • an adhesive cord 15 known for insulating webs.
  • Fig. 2C the two receptacles 6c and 6c' of the insulating webs 4c and 4c' are identical.
  • the ends of the longitudinal edges of the plastic bridge web 5c used are angled in this exemplary embodiment.
  • the smaller angle of the angled end 16 in the fixed bearing of the insulating web 4c leads to a positive fit and the 90 ° bend of the end 16 'leads to play in the floating bearing of the insulating web 4c'.
  • Fig. 2D shows a modified design with insulating webs 4d and 4d', in which the receptacles 6d and 6d' are used to accommodate the longitudinal edges of the bridge web shown there 5d are designed like a rail.
  • the ends 16 and 16 'of the plastic bridge web 5d shown are T-beam shaped.
  • the end 16 in the receptacle 6d is arranged in a form-fitting manner in the receptacle 6d to form the fixed bearing.
  • the end 16' of the bridge web 5d is again contained with a play in the floating bearing of the insulating web 4d'.
  • Fig. 3 shows a composite profile 1 according to the invention with two aluminum profile half-shells 2 and 3, in the insulating webs 4d and 4d 'analogous to the training in Fig. 2D , are inserted.
  • the necessary small play can be achieved by appropriately machining the bridge webs with a variably adjustable control of the frictional resistance before or during insertion into the receptacles of the insulating bars.
  • the bridge webs 5d some of which still protrude from the receptacles, have elements in the contact area with the receptacles 6d' of the insulating web 4d' to increase the frictional resistance in the longitudinal direction of the bridge webs 5d.
  • these elements are designed as tabs 17, which are connected on one side to the (in the Fig. 3 upper) end 16 'of the bridge webs 5d are aligned, namely in the insertion direction and against the insertion direction, as in Fig. 3 can be seen, are bent upwards slightly in order to achieve a jamming to increase the frictional resistance when inserted.
