Definitions

  • the present invention relates to a glazing panel.
  • the present invention relates to a glazing panel comprising at least two parallel outer glazing panes spaced apart from one another by means of a spacer frame structure and wherein one glazing pane surface of each outer glazing pane is a bonded glazing pane surface which is bonded to a lateral side of the spacer frame structure.
  • the window frame supports and bears the glazing panel and is providing the structural strength needed in order to restrict deformations of the window and to withstand loads exerted on the window, such as wind loads, loads exerted during opening and closing or wrong manipulation of the window by a person and so on.
  • the glazing panel or insulating glazing is considered as being a transparent plate which just completes the window and which is not fulfilling any structural function such as a bearing, a supporting or a load taking function.
  • window frame is forming a non-transparent part of the window with relatively important dimensions compared to the total window surface, so that incident light is partly obstructed.
  • the existing windows are also rather inefficient thermal insulators, since the window frame is usually a rather weak thermal insulator, at least compared to the double glazing panels.
  • glazing panels are also used to construct a so-called curtain wall, which have a higher transparency ratio than the traditional windows.
  • thermoforming panel with a very high structural strength which is able to withstand loads similar to the loads usually applied on a known window, without the need of an outer window frame or supporting structure.
  • the present invention relates to a glazing panel comprising at least two parallel outer glazing panes spaced apart from one another by means of a spacer frame structure, one glazing pane surface of each outer glazing pane being a bonded glazing pane surface which is bonded to a lateral side of the spacer frame structure, wherein said lateral sides of the spacer frame structure are provided with a protrusion which supports the corresponding bonded glazing pane surface, a slot being left adjacent to the protrusion between the concerned lateral side of the spacer frame structure and the concerned bonded glazing pane surface, the slot being at least partly filled with an adhesive material.
  • a big advantage of such a glazing panel according to the invention is that its spacer frame structure has an adapted shape which enables the realization of a glazing panel which is extremely strong and which can be used as a structural building component rather than as a decorative element without any load bearing function.
  • the protrusions at both lateral sides of the spacer frame structure provide in the necessary support for the outer glazing panes, while at the same time a limited deformation of the outer glazing panes or a pivoting movement around the concerned protrusion is still possible in the space available in the adjacent slots, at least if an adhesive material is applied, which is not too stiff and therefore suitable for this purpose.
  • glass has a very high strength and stiffness, these interesting physical characteristics being completely neglected for load bearing functions in the present known glazing panels.
  • a glazing panel according to the invention can be mounted without using any additional outer window frame or other supporting structure and has therefore a lot of advantages such as maximal transparency and as a consequence maximal sun light penetration, a very high thermal insulation, visual uniformity between fixed glazing panels and panels that can be opened and closed, as well as visual uniformity between glazing panels used at varying positions in a building, as for example in a front side, a roof or an inside wall and so on.
  • a preferred embodiment of a glazing panel according to the invention is a self-supporting glazing panel, having sufficient structural strength for bearing at least the weight of the glazing panes of the glazing panel as well as for supporting a wind load of 1600 Pa applied perpendicular to a surface of one of the outer glazing panes, without the need of an outer supporting sash frame for supporting the glazing panel.
  • a glazing panel or window that withstands a wind load of about 1600 Pa is suitable for being applied in normal situations on buildings which are subjected to normal wind loads, such as glazing panels for buildings in cities at a height below certain heights.
  • the spacer frame structure has an outer border which fits within the outer border of the outer glazing pane with the largest dimensions.
  • Such an embodiment of a glazing panel according to the invention provides maximum transparency and is actually a real structural glazing panel that does not need any outer structural or load bearing support.
  • the present invention also relates to an assembly of a multitude of glazing panels according to the invention wherein adjacent glazing panels are connected to one another by connecting spacer structure frames of adjacent glazing panels, in order to form an assembly which behaves as a single, self-supporting structural glazing panel and this without the need of enclosing the outer borders of the glazing panels in an additional outer supporting frame.
  • Such an assembly according to the invention is very suitable for realizing curtain walls or other building structures in a very simple way, the glazing panels being capable of withstanding the loads without the need of other load bearing elements or with just a minimal amount or very light outer frame structures, such as profiles or joint structures for making the assembly wind and rain tight etc...
  • the invention provides therefore also in a complete new way of building with glazing panels, wherein the strength of the glass is used to a maximum.
  • the assembly 1 of glazing panels according to the invention represented in figure 1 comprises four glazing panels 2 according to the invention and is an application wherein the glazing panels 2 are used for realizing a window in an opening 3 of a building 4.
  • such a glazing panel 2 comprises two parallel outer glazing panes 5 and 6 spaced apart from one another by means of a spacer frame structure 7.
  • a glazing panel 2 in accordance with the invention has additionally intermediate glazing panes 8 or intermediate transparent panes made of a synthetic material.
  • three glazing panels i.e. glazing panels 9, 10 and 11, are fixed glazing panels, while the remaining glazing panel 12 is a glazing panel that can be opened and closed.
  • Glazing panel 12 is therefore hinge mounted by means of hinges 13 on the adjacent fixed glazing panel 10, while it is supported in the closed status against locking points 14 at a border 15 of the other adjacent glazing panel 11.
  • Neighbouring fixed glazing panels 9 and 10 are interconnected at discrete positions which are distant from one another by means of coupling elements 17, which are directly attached to the spacer frame structures 7 of the concerned glazing panels 9 and 10.
  • the complete assembly 1 of glazing panels 2 is in this case surrounded by a framework 18, which is mounted in the opening 3 between the assembly 1 of glazing panels 2 and the building 4, each of the glazing panels 9, 10 and 11 being connected to this framework 18 by means of similar coupling elements 19 at discrete positions which are distant from one another.
  • the framework 18 itself is fixed in the building structure 4 by means of anchors 20, such as concrete anchors 20 or the like.
  • the framework 18 is however nothing like a window frame known according to the state of the art for supporting and bearing a known glazing pane.
  • the hardware consisting of hinges 13, locking points 14 and the window handle 16 are also directly and exclusively mounted on the concerned spacer frame structures 7 for supporting and bearing the hinged glazing panel 12 in the neighbouring glazing panels 10 and 11 of the assembly 1.
  • the spacer frame structure 7 and the bond of this spacer frame structure 7 with the outer glazing panes 5 and 6 and possible intermediate panes 8 is designed in such a way that the glazing panels 2 have enough structural strength in order to withstand the loads, such as the load due to the weight of the glazing panes 5 and 6, wind load, loads of neighbouring panels and so on, without the need of enclosing the outer glazing panes 5 and 6 between two profiled parts of a window frame, as is the case with the known window designs.
  • the framework 18 can therefore be a very lightweight frame which has no particular structural strength and must be considered in this case as a simple aid for installing the assembly 1 of glazing panes 2 into the opening 3 in the building 4, which opening 3 can for example be an opening 3 of an unfinished building 4 having edges with a lot of irregularities.
  • the glazing panels 9 and 12 in accordance with the invention are essentially only bearing their own weight and loads on their own surface and are for this reason indicated as being self-supporting glazing panels 9 and 12.
  • glazing panel 10 is bearing at one edge 21 adjacent glazing panel 12 by means of hinges 13 and will be indicated as being a load bearing glazing panel 12, whereas glazing panel 11 is only partly bearing load from the neighbouring hinged glazing panel 12 and is therefore indicated as being a semi-load bearing glazing panel 11.
  • FIG. 2 illustrates another assembly 1 of glazing panels 2 according to the invention, this time in a vertical curtain wall 22 application, wherein no framework 18 is used at all, adjacent glazing panels 2 being interconnected at their vertical edges 23 by means of elongated coupling elements 24 which act again directly on the corresponding spacer frame structures 7 of the concerned glazing panels 22.
  • the glazing panels 22 have according to the invention again a sufficient intrinsic structural strength and load bearing capacity to withstand the loads on the curtain wall 22.
  • glazing panels 2 of the assembly 1 are mutually coupled or that glazing panels 2 of the assembly 2 are coupled to a framework 18, a building structure 4 or the like by means of one more coupling elements 17, 19 or 24, which are attached directly onto the spacer frame structure 7 of the concerned glazing panels 2 and which prevent a movement of the glazing panel 2 in a direction AA' perpendicular to the glazing panes 5 or 6, while allowing small movements in other directions in order to accommodate dilatation of the glazing panels 2 due to temperature change.
  • FIG. 3 is a cross-sectional view through a first embodiment of a glazing panel 2 according to invention, which has all the basic characteristics necessary in order to obtain the aforementioned structural strength of the glazing panel 2.
  • Each outer glazing pane 5 and 6 has two glazing pane surfaces 25 and 26.
  • a pair of outside glazing pane surfaces 25 of the glazing panes 5 or 6 forms essentially the outside of the glazing panel 2, the outer glazing pane surfaces 25 being in contact with the outer environment.
  • a pair of inside glazing pane surfaces 26 of the glazing panes 5 and 6 forms essentially the inside of the glazing panel 2.
  • the inside glazing pane surfaces 26 are bonded glazing pane surfaces 26, since they are each bonded to one of the lateral sides 29 of the spacer frame structure 7.
  • said lateral sides 29 of the spacer frame structure 7 are furthermore provided with a protrusion 30, which supports the corresponding bonded glazing pane surface 29.
  • a slot 31 is left between the concerned lateral side 29 of the spacer frame structure 7 and the concerned bonded glazing pane surface 26.

  • the spacer frame structure 7 has an outer border 33 surrounding the glazing panel 2 and which fits within the outer border 32 of both outer glazing panes 5 and 6.
  • the slots 31 are completely filled with an adhesive material 34.
  • the bonded glazing pane surfaces 26 are bonded to the corresponding lateral side 29 of the spacer frame structure 7 in a region in the vicinity of their circumference or outer border 32.
  • the bonded glazing pane surfaces 26 are supported on a corresponding protrusion 30 of the spacer frame structure 7 at an inward area of said region, which inward area is at some distance from the adjacent outer border 32 of the concerned bonded glazing pane surface 26.
  • the spacer frame structure 7 is in this embodiment also composed of a single spacer frame 35 and can be fabricated of a metal such as aluminum, steel or whatever other metal.
  • spacer frames 35 of a glazing panel 2 in accordance with the invention are fabricated from glass-fiber reinforced polyester or glass-fiber reinforced polyurethane.

  • a glazing panel 2 according to the invention represented in figure 12 is quite similar, but has all kinds of hook shaped edges 39 formed by outer flanks 45 and intermediate flank 50, a crumple zone 46 being also provided in the form of a central part 47 of the bottom 44 which is offset with respect to the outer parts for the bottom.
  • the spacer frame structure 7 in the glazing panel 2 of figure 12 has also a rather limited rigidity against forces applied in the lateral direction, so that also a lateral flexibility is present in this embodiment of figure 12 , allowing small lateral movements of the outer glazing panes 5 and 6 towards one another or away from one another, as is illustrated in figure 12 by means of dash lines.
  • the spacer frame structure 7 has in the examples of figures 11 and 12 an outer border 33 which fits within the outer border 32 of the outer glazing pane 5 with the largest dimensions.
  • Figures 13 and 14 illustrate in perspective view how a spacer frame structure 7 as well as a glazing panel 2 according to the invention are assembled.
  • the structural spacer frame 7 consists of rectilinear parts 54 which are connected to one another in corners by means of inserts 55 which are slid in the groove 37 forming the attachment means 37 and which are further bonded by means of an adhesive material 34 to the rectilinear parts 54.
  • the present invention is by no means limited to glazing panels 2 or assemblies 1 of such glazing panels 2 according to the invention described as examples and illustrated in the drawings, but such glazing panels 2 or assemblies 1 of such glazing panels 2 according to the invention can be realised in all kinds of variants, without departing from the scope of the invention.
