Definitions

  • the present invention relates generally to a composite construction for fixed and movable surface elements, such as windows, doors, panels and facade elements, as well as the fixed or movable surface elements themselves obtainable thereby.
  • composite profiles and composite profile frame systems are known from the state of the art. They are preferably made of metal or a metal alloy and can be exposed to adverse weather conditions and strong temperature fluctuations between their inside and outside. A large temperature difference between the outside of the profile frame system, i.e. the side located outside the building, and the inside of the profile frame system generally proves to be problematic from a thermal engineering perspective. To prevent thermal bridging, such composite profile systems usually connect two metallic frame profiles (inner and outer profiles) using one or more less thermally conductive plastic insulating strips, also called separating strips, to achieve thermal separation or decoupling between the inside and outside.
  • connection between the two frame profiles and the separating webs must, of course, simultaneously meet other structural requirements, such as loads due to tension or compression, shear, bending and torsion, as well as aesthetic requirements, the problem of the so-called bimetallic effect arises with increasing size due to the above-described thermal separation within the connection while simultaneously maintaining a force-fit connection.
  • the bimetallic effect occurs when two materials with different thermal expansion coefficients are connected and deformation occurs due to the different expansion.
  • Such difficulties due to repeated large temperature differences mainly occur in surface elements in external walls. This deformation occurs, for example, in winter between the interior and exterior air, and in summer when solar radiation causes the temperature of the exterior profile to rise.
  • FR 3 099 199 A1 shows a composite construction according to the preamble of claim 1.
  • An object of the present invention is to provide a composite profile system for windows, doors and facade elements, especially for movable elements with large dimensions, which reliably prevents the bimetallic effect and thus largely prevents deformation, warping and generally the malfunctions caused thereby in terms of sealing, opening/closing and/or locking.
  • a composite construction for fixed and movable surface elements such as windows, doors, panels and facade elements, in particular movable Surface elements
  • the composite construction comprises a surface filling, in particular a multiple glazing or a composite panel, with a plurality of first composite profiles as a frame, wherein the first composite profiles each have an outer profile, an inner profile and one or more first separating webs connecting the outer profile and inner profile, wherein the connection of the outer profile and the inner profile is equipped without any sliding in the longitudinal direction (e.g. by means of separating webs which are free of sliding or attached without any sliding).
  • the outer profile is attached to an outer side of the edge region of the filling in the longitudinal direction in a first longitudinal section of at most 5% of the length of the outer profile in a shear-resistant manner to the filling, but without shear over the remaining length, e.g. the first longitudinal section represents between 0.1 and 4%, in particular between 1 and 3% of the length of the outer profile (at room temperature).
  • the shear-resistant region can be located at any point along the length/longitudinal direction of the outer profile, it is preferably located at one end or in an end region of the outer profile in order to direct the temperature-induced expansion in one direction, wherein the end region extends at most over a distance of at most 10% of the length of the outer profile.
  • this is preferably the lower end or the lower end region.
  • this shear-resistant region can be provided at/in the left or right end/end region.
  • the inner profile is attached to the filling in a shear-resistant manner against an inner side of an edge region of the filling in the longitudinal direction in a second longitudinal section of at least the length of the first longitudinal section.
  • the frequently required size/height also means that the composite profile on the handle side is subjected to very strong stress, mainly when closing due to central pulling.
  • the shear-resistant second length section can make up at least 25%, preferably at least 40% or more than 60% of the length of the inner profile (at room temperature) or even the entire length of the inner profile. If the entire length is not equipped with a shear-free design, the shear-resistant second length section is advantageously divided into several shear-resistant partial length sections, but over essentially the entire Distributed along the length of the inner profile. This enhanced shear-resistant design of the inner profile toward the filling simultaneously achieves even greater stability of the frame, particularly in terms of tensile strength perpendicular to the profile and parallel to the plane of the filling.
  • inside and outside are to be understood in such a way that “inside” is the side on which the smallest temperature fluctuations are expected over the period of use, whereas the term “outside” refers to the side opposite the surface of the surface element, i.e. the side subject to the greatest temperature differences.
  • the infill of the composite construction can be any known type of suitable flat material, e.g., a sandwich panel or multiple glazing.
  • the aforementioned edge area can be the outer edge of the infill itself.
  • the edge area is preferably an additionally attached surround, e.g., in the form of a U-profile made of suitable plastic, which is optionally placed on the edge area of the multiple glazing and preferably glued in place.
  • Such a surround can be attached during the manufacture of the multiple glazing and thus also reliably protects the glazing from damage during transport to the installation site.
  • a shear-resistant connection can be achieved using suitable means and methods, e.g., by screwing, gluing, form-fitting, etc. It is preferably created using one or more shear-resistant supports, with the shear strength advantageously being achieved by the force and/or form-fitting of an appropriately shaped tongue on the shear-resistant support in a groove in the edge area of the panel.
  • a particularly suitable shear-resistant feature is a toothed arrangement of the appropriately shaped tongue. If a form-fitting arrangement is (additionally) desired, the edge area of the panel and/or the groove can have a corresponding counter-toothing arrangement.
  • a shearless or sliding connection is preferably made by means of one or more shearless brackets spaced apart in the longitudinal direction of the composite profile, wherein the connection of the shearless bracket to the filling is made, for example, by a guide in a groove of the edge area of the filling.
  • the sliding spring of the thrustless mount usually has a rounded cross-section.
  • a shear-resistant connection of the outer and inner profiles in the shear-resistant area can also be made simultaneously by a shear-resistant block attached to both profiles.
  • the invention further relates to a fixed or movable surface element, such as a window, a door, a panel or a facade element, in particular a movable surface element, comprising at least one composite construction as described above.
  • a fixed or movable surface element such as a window, a door, a panel or a facade element, in particular a movable surface element, comprising at least one composite construction as described above.
  • such a composite construction is fixedly or movably mounted in or on a composite frame, wherein the composite frame comprises a plurality of second composite profiles, wherein the second composite profiles each have an outer shell, an inner shell and one or more second separating webs connecting the outer shell and inner shell.
  • the invention relates to movable surface elements such as, for example, a sliding element in a composite frame, wherein the sliding element has multiple glazing as a filling and wherein a number of rollers are arranged on the underside of the profile construction in a manner distributed along the length so that, in use, the sliding element is moved by guiding the rollers on a guide rail mounted on the lower part of the composite frame.
  • movable surface elements such as, for example, a sliding element in a composite frame, wherein the sliding element has multiple glazing as a filling and wherein a number of rollers are arranged on the underside of the profile construction in a manner distributed along the length so that, in use, the sliding element is moved by guiding the rollers on a guide rail mounted on the lower part of the composite frame.
  • the first separating webs, the second separating webs, the shear-resistant block and/or the enclosure are preferably made of a material selected from the group consisting of polyamide; polyolefin, e.g., polypropylene; polyester, e.g., polyethylene terephthalate or polybutylene terephthalate; acrylonitrile butadiene styrene; polyvinyl chloride or mixtures or combinations thereof; if required or desired, the material is fiber-reinforced, e.g., glass fiber-reinforced.
  • the Figures 1 and 2 illustrate the bimetal effect that can occur with conventional sliding elements 20 (state of the art), e.g. in the case of a glazed sliding door, whereby the problem is caused by high Temperature differences between the outside and inside and larger dimensions of the sliding elements 20 are increased.
  • the Fig. 2a shows on the left a cross-section and on the right a longitudinal section through (or a plan view of) a conventional composite profile of a sliding element 20 at approximately the same temperatures on the inside and outside, in this case the vertical composite profile 20 towards the opening side of the sliding element.
  • the composite profile 20 firmly/positively connects an outer profile 21 to an inner profile 22 via one or more insulating webs 23 designed as thermal separation, wherein the inner and outer profiles 21, 22 are usually made of metal, e.g. aluminum, and the insulating webs 23 are formed from a plastic material, possibly (glass) fiber reinforced, e.g.
  • each of the profiles 21, 22, as well as the separating web 23, has a length L in the longitudinal direction x.
  • the outer profile 21 expands by an additional length ⁇ x in the longitudinal direction x.
  • the composite profile 20 bulges outwards due to the so-called bimetallic effect.
  • the extent of the bulge ⁇ y in the transverse direction can lead to the sliding element hitting the side part of the profile frame 10, as shown in Fig.
  • Fig. 1a consequently shows a conventional closed sliding element 20 (with double glazing as filling 29) in its frame 10 with small temperature gradients (or no temperature difference) between the outer profile 21 and inner profile 22 of the composite profile of the sliding element 20.
  • Both profiles 21, 22 have parts that can serve as handles 25, 26 for operating the sliding element.
  • both profiles 21, 22 are rigidly/positively connected by one or more separating webs 23, e.g. by rolling up or forming a collar, etc. These separating webs 23 enable the thermal insulation function of the composite profile 20 because they act as a thermal break and thus greatly reduce heat transfer by conduction from the inside to the outside or from the outside to the inside.
  • the frame 10, within which the sliding element 20 can move, is constructed in principle similarly as a composite profile with an outer frame part 11 and an inner frame part 12, which are thermally separated and non-positively connected by one or more separating webs 13.
  • the frame has a U-shaped cross-section facing the sliding element, in which the outer region of the composite profile of the sliding element 20 is located when closed.
  • the wind- and heat-sealing function can be supplemented by additional aids 17, 18, such as brush, felt, or rubber seals.
  • Fig. 1b shows the situation in the case of a large temperature difference between the outer and inner profiles 21, 22: T outside > T inside .
  • the same reference numerals indicate the same elements as in Fig. 1a .
  • the cross section here again for example at half height of the sliding element 20, shows that the outwardly curved part of the sliding element 20 can no longer be easily guided into the U-shaped cross section of the frame 10 (see highlighted point in the Fig. 1b ). In other words, the sliding element 20 will hit the frame with its outer profile 21 and possibly damage it or even prevent the complete closing of the Prevent sliding element 20.
  • Locking (with locking means not shown here) of the sliding element 20 would therefore possibly even be impossible in this case, as long as the temperature difference between the outer and inner profiles 21, 22 is above a certain value. It may be necessary to wait until this temperature difference has decreased sufficiently, i.e. until ⁇ y has decreased sufficiently, that the outer profile 21 of the sliding element 20 can be moved back into the U-shaped cross-section of the frame 10. However, damage that has already occurred to the frame 10 or to the composite profile of the sliding element 20 cannot be reversed by this.
  • FIG. 3 An embodiment of the invention is shown using the example of a sliding element 200 in a frame 100 in cross section, wherein the cross section is located, for example, approximately halfway up the frame 100.
  • the frame (second composite profile) 100 is formed by an outer shell 111 and an inner shell 112, which are rigidly/positively connected by one or more separating webs 113.
  • the frame 100 forms a U-shaped cross-section for accommodating the outer edge of the sliding element 200 in the closed state.
  • wind and heat-sealing aids 117, 118 such as flexible sealing lips, are provided for sealing in the closed state.
  • the U-shaped cross-section is preferably provided with a lining plastic profile 115, which is connected to the elements of the frame 100, e.g., by push-on or clip connections.
  • This lining plastic profile 115 can additionally serve as a stop for the sliding element 200. In such cases, it may be appropriate to provide the side of the lining plastic profile 115 facing the sliding element with a shock-absorbing lining 116, e.g., a flexible rubber or foam insert. It may also be appropriate to provide (spring-loaded) support for the lining plastic profile 115 against the separating web 113 located behind it.
  • a shock-absorbing lining 116 e.g., a flexible rubber or foam insert. It may also be appropriate to provide (spring-loaded) support for the lining plastic profile 115 against the separating web 113 located behind it.
  • the sliding element 200 is also an example of a glazed sliding door, e.g. with triple glazing as filling 290.
  • the Composite profile of the sliding element 200 has an outer profile 221 and an inner profile 222, which are connected by one or more separating webs 213.
  • separating webs are provided here which are either firmly connected to only one of the two outer and inner profiles 221, 222 and are held on the other profile via a sliding profile, or, as in Fig. 3 as an example, which are two (or more) parts, with one part being rigidly/positively connected to one of the two profiles and a second part being connected to the other profile, but these two parts are joined together so that they slide in the longitudinal direction of the profiles.
  • shearless separating webs By means of these, in themselves known, so-called shearless separating webs, a certain differential expansion between the outer and inner profiles 221, 222 is in principle possible.
  • the use of such shearless separating webs in the connecting profiles of the sliding element frame not only results in a general reduction in the flexural rigidity of the connecting profiles, but also in the outer and inner profiles in each of the connecting profiles being able to move differently in the longitudinal direction x, as a result of which the sliding element frame can warp completely or partially.
  • the filling 290 of the sliding element 200 e.g. a triple glazing as in Fig. 3 shown, provided with a frame 261 and on the other hand, the inner profile 222 is connected to the frame 261 in a shear-resistant manner on a second length section SF2 (here as an example the sum of the four shown partial length sections SF2 i , ie SF2 a + SF2 b + SF2 c + SF2 d ) of length L, but the outer profile 221 is only connected to the frame 261 in a shear-resistant manner at one point, the first partial section SF1, particularly preferably at one end or an end region E of length L.

  • both profiles 221, 222 are again in the same position. to each other and to the filling 290.
  • the same principle applies to a vertical profile opposite the filling 290, which can therefore only expand in this direction. This ensures that the shear stress of the bimetallic effect has the same effect on both sides of the sliding element and that shearing of the sliding element frame does not occur.
  • the horizontal composite profiles at the top and bottom edges of the sliding element can also be equipped in the same way, with the shear-resistant point (end area) on the outer profile preferably being located on the opening side.

  • a (partially) shear-free connection of the enclosed filling can be achieved by simply guiding it within a suitable boundary; however, movement transverse to the shear direction must then be largely prevented by other means, e.g., by locating the enclosed filling within a U-shaped cross-section of the composite profiles. In practice, however, such a "loose" connection would often be inadequate.

  • the shear-free connection by the shear-free brackets 241 between the outer profile 221 and the enclosure (not shown) of the filling prevents the bimetallic effect from occurring.
  • the outer profile 221 can expand in the longitudinal direction ( ⁇ x) without affecting the connection: the shear-free brackets 241 can move freely with respect to the enclosure in the longitudinal direction with the outer profile 221, regardless of any expansion of the enclosure, but due to the bottom shear-resistant bracket 242 on the outer profile 221, they can only move in the direction (see arrows in Fig. 4b ) at the top (Top).
  • the position of the non-sliding brackets 241 therefore changes progressively by a distance that increases with the temperature difference and the distance from the non-sliding bracket 242. If the non-sliding bracket 242 of the outer profile is located at the lower end, as is the case here, and the relative movement of the furthest non-sliding bracket consequently approaches the linear expansion ⁇ x caused by the temperature difference without the assembly being subjected to warping, the sliding element 200 can be opened and closed easily and reliably, even with large temperature differences between the outer and inner profiles.
  • Fig. 5 a section similar Fig. 4b , with a different/additional shear-resistant connection of the construction, whereby the cross-section shown on the left, in contrast to Fig. 4b bottom (bottom) through the sliding element.
  • a shear-resistant block 280 can also be provided, which is fixed to both outer and inner profiles 221, 222, e.g. by means of suitable fastening means 281, such as screws, and thus reliably directs the expansion of the outer profile 221 in one direction (e.g. upwards) in the event of large temperature differences.
  • this shear-resistant block 280 is preferably made of plastic, e.g. like the (glass) fiber-reinforced polymers and poly blends commonly used for dividers.
