Definitions

  • the invention relates to a holding structure for insulating glass panes, in particular for space-forming glazing such as conservatories, pavilions and the like. They are usually made of multiple-pane insulating glass and include a steel construction that is designed as unobtrusively as possible in order to impair the "airy" and light-flooded impression of the glass structure as little as possible.
  • the DE 2010 015 999 U1 relates to an arrangement with a roof glazing supported by beams, this and the side walls being made of glass panes and in which the beams are supported by vertical supports.
  • the supporting beams each consist of strip-shaped laminated glass plates consisting of several glass panes, with the connection between a support and a beam being made by correspondingly shaped metal parts, which are placed between two glass panes in a section of a glass pane lying between them or by further metal parts between the two glass panes , an insulating glass panel forming the roof glazing and/or a side wall, are attached and glued to them.
  • the mechanical connection between two glass plates is created by the relevant metal parts.
  • the viability of this arrangement is limited.
  • the DE10 2013 217 600 A1 relates to a glass facade with an internal support structure, which comprises at least one support element and at least two glass facade elements, the glass facade elements being connected to the at least one support element on at least one fastening edge.
  • the support element has two wings, each of which engages in laterally open intermediate spaces between the glass panes, the support element and the glass facade elements being designed in such a way that the support element is essentially completely surrounded by the glass facade elements in a plane perpendicular to its longitudinal extent. In the absence of anchoring of the support element to a support structure beyond the glass panes, it should only serve to connect the glass panes to one another, but otherwise be largely insignificant in terms of statics.
  • the object of the invention is therefore to specify an all-glass construction for conservatories, pavilions or the like made of insulating glass panes which has a high load-bearing capacity and whose steel construction is nevertheless visually as inconspicuous as possible.
  • the holding structure comprises a steel profile that can be mounted on an abutment and at least two insulating glass panes with an edge bond at their edges, with a butt joint between the insulating glass panes, with the steel profile acting as an anchor or at least as a partial section of an anchor in the butt joint and parallel to the edges and engages with at least one section in the edge bond of an insulating glass pane and has coupling points for the connection to the abutment, with which it is either flush with the glass panes on the abutment or extends out of the butt joint of the glass panes.
  • an anchor In construction, an anchor is a component that, due to its tensile strength, connects different and usually dissimilar components to one another.
  • insulating glass panes of a glass front can be anchored to an independent building as an abutment made of steel or reinforced concrete.
  • wind pressure and suction forces can act on vertically positioned insulating glass panes, which the anchor must absorb and transfer to the abutment in order to ensure the stability of the glass front of a conservatory, for example.
  • the construction according to the invention is therefore based on an abutment such as a building exterior wall or a steel construction, to which it and in particular the steel profile is connected. It therefore does not represent a statically completely independent all-glass construction.
  • the individual panes of your multiple-pane insulating glazing consist of individual panes with an edge bond on which the individual panes are glued and sealed together airtight to form an evacuated or gas-filled space between the panes.
  • the edge bond primarily forms a narrow end face of an insulating glass pane.
  • spacers are glued in between the individual panes in order to ensure not only a defined distance but also a peripheral sealing of the space between the panes.
  • Insulating glass panes lying next to one another meet at the butt joints, so that the edge seal of a first insulating glass pane comes to lie parallel next to the edge seal of a second insulating glass pane.
  • a butt joint can basically occur between two insulating glass panes that are largely in one plane. In contrast to a scale joint, the insulating glass panes do not overlap at such a joint.
  • One Butt joints can also occur between two insulating glass panes that are at an angle to one another. At the corner of a building, the angle is regularly 90°, but can deviate from this both in the direction of higher values and in the opposite direction. According to the invention, the insulating glass panes overlap at one corner only on the front side of one insulating glass pane.
  • the steel profile runs essentially in the area of the butt joint, so that it is arranged between the two insulating glass panes of a butt joint and thus runs parallel to the edges of the insulating glass panes.
  • This alone allows the steel profile to be arranged in a very unobtrusive manner.
  • a section of the steel profile engages in the edge seal of an insulating glass pane in order to hold it from its narrow front side. Unlike gripping around the edge of the insulating glass pane, the engagement of the steel profile in the edge seal represents a quasi "invisible" holding device for the insulating glass pane.
  • the steel profile and its section engaging in the edge seal are "hidden" in the butt joint or in the edge seal.
  • the invention thus uses the edge seal of the insulating glass pane, which is required anyway, in addition to its attachment to the steel profile. In contrast to a screw connection in the edge seal perpendicular to the plane of the pane, no time-consuming drilling through a glass pane is required. Rather, the invention offers the possibility of both a linear and a punctiform mounting of the insulating glass pane on the edge bond. It can thus be adapted to different loads with little design effort, for example by varying the distances between the sections in the case of a punctiform mounting or by varying the length of the sections in the case of a linear mounting.
  • the steel profile according to the invention finally offers cuts or coupling points, usually at its longitudinal ends, with which it connects, for example, flush with the glass panes on the abutment or extends out of the butt joint of the glass panes.
  • the steel profile can form a ring beam or at least a section of a ring beam.
  • the ring anchor is a ring-shaped, closed component made of steel that prevents the insulated glass panes that have been wrapped around or connected from falling apart by absorbing a thrust that is introduced into the insulating glass panes perpendicular to their plane of extension. If the ring anchor is made up of individual sections, the connections between the sections must be able to absorb sufficient tensile stress.
  • the ring anchor can Assemble the steel profile and an abutment to which the steel profile connects.
  • the abutment can itself consist of a steel structure or a concrete structure which is steel reinforced. In any case, the abutment complements the steel profile - not necessarily in geometric terms, but at least in static terms - to form a ring.
  • the cross-section of the steel profile should be dimensioned as slim as possible.
  • the steel profile - especially in the case of an out-of-round ring anchor - cannot be buckling-resistant enough to be able to absorb horizontal forces, especially on longer, flat glass fronts.
  • the steel profile can therefore have at least one coupling section for connecting a tension element orthogonal to its direction of extension.
  • the tension element can support the steel profile on the abutment or brace it against the abutment.
  • the tension element can also provide support or bracing on an opposite steel profile as a section of the same ring anchor.
  • the coupling section is not located at the ends of the steel profile, but in its course beyond or outside of its ends in order to support the steel profile in a central area.
  • Several coupling sections are also conceivable and useful. Because the use of a tension element shortens a significant free support length of the steel profile and the steel profile can thus absorb greater horizontal loads than its cross section or its area moment of inertia alone would allow, longer facades made of insulating glass panes can be constructed if tension elements are used.
  • the steel profile can form a tie rod from an anchor head and an anchor shaft.
  • the anchor head is the section of the steel profile that is held in the edge bond of the insulating glass pane.
  • the anchor shank is formed by a coupling section of the steel profile running transversely thereto, which enables connection to a tension element.
  • the anchor shank thus offers a fastening surface for fastening the tension element, so that it can transfer forces to an abutment orthogonally to the direction in which the steel profile extends.
  • the orientation of the anchor shaft itself is of secondary importance as long as the tension element can be attached to it in the force transmission direction of the anchor.
  • the section of the steel profile that engages in the edge seal must always be permanently fastened there. It can be wedged, wedged, latched or otherwise in the edge seal to be attached. According to a further advantageous embodiment of the invention, the section of the steel profile is glued in the edge seal. As a result, a sufficiently permanent attachment can be achieved, which can be carried out on site at a reasonable cost without the use of additional construction means and without taking into account narrow tolerances. Silicone adhesives in 2-component technology, for example, are known as suitable adhesives.
  • the low demands on tolerances between the sections of the steel profile on the one hand and the edge bond of the insulating glass pane on the other hand enable the components of the holding structure according to the invention to be manufactured at low cost.
  • the edge bond has a receiving pocket in which the section of the steel profile is or is glued. It can represent a separate component that is introduced into the edge seal, or it can be formed in the spacer of the edge profile.
  • the material of the receiving pocket on the one hand and the material of the section on the steel profile on the other allow the definition of suitable adhesive partners to which the adhesive can be matched.
  • the arrangement of the receiving pocket can allow its material to be matched to the adhesive independently of the remaining material of the edge composite.
  • the possibly separate receiving pocket can be attached to the edge seal in the factory and thus with high quality, durability and reliability.
  • the arrangement of a receiving pocket in the edge bond offers the possibility of defining the dimensions of an adhesive joint between the receiving pocket on the one hand and the section of the steel profile on the other hand, in particular in accordance with the static requirements.
  • the same receiving pocket can always be formed or used, which means that the same or repeatable conditions can be achieved when gluing even with different dimensions of insulating glass panes or their edge seal. This means that the bonding can be of high quality, especially if it is done on site.
  • a required or desired adhesive thickness can also be set and the adhesive joint can be calculated more reliably.
  • the receiving pocket can be designed as a U-profile glued into the edge seal. It thus forms a defined interface in the insulating glass pane for integrating the section of the steel profile, which can be configured linearly or at points or loaded.
  • the U-profile can, for example be made of aluminum or plastic, which means that it can be produced with little effort and integrated into the edge seal of the insulating glass pane using known technologies.
  • a section of the steel profile is integrated into the insulating glass pane or into its edge seal.
  • the section of the steel profile can engage in the edge bond linearly, for example with a profile leg, or selectively.
  • the section can be designed as a lug which is formed on the steel profile. It can be welded on separately there or cut out of the steel profile. In this way, it defines a selective fastening of the steel profile, which can have a linear effect due to a large number of brackets lying next to one another.
  • a punctiform attachment can be advantageous with regard to the production of the bond, because it can offer shorter adhesive joints, a smaller adhesive surface and thus the advantage of less effort. It can also be structurally sufficient, for example by engaging in the edge seal of an insulating glass pane at only two points.
  • the inventive engagement of the steel profile in the edge seal of the insulating glass pane essentially transmits forces in a direction perpendicular to the insulating glass pane held, mostly wind pressure and wind suction forces.
  • the steel profile can also be held or fastened in the butt joint between the insulating glass panes.
  • the mount can be linear or point-by-point, for example by blocking or gluing.
  • a suitable force transmission possibly over the largest possible area, can be achieved, in particular of compressive forces between the insulating glass panes on the one hand and the steel profile on the other.
  • the bracket can lead to a low surface pressure in the area of the edge bond of the insulating glass panes.
  • a punctiform attachment can reduce the costs for the gluing and its effort, achieve ventilation or drainage between the glue points and thus avoid condensation.
  • the steel profile can be statically better utilized by being subjected to at least one other direction of force, namely in one of the two remaining spatial directions perpendicular to the plane of the insulating glass slide, in whose edge bond the section of the steel profile engages.
  • the steel profile itself can or only needs to be (closed) between the insulating glass panes. With the load-bearing blocking of the steel profile and the gluing of its section in an edge bond, an articulated and non-positive connection of two insulating glass panes can be achieved achieve. As a result, the adhesive joints of the bond are only loaded by normal stresses and shear stresses in the joint axis, which benefits their durability.
  • the cross-sectional shape of the steel profile can advantageously be adapted to the respective installation situation, so that the steel profile remains visually as inconspicuous as possible.
  • it can have a tubular cross-section or a T or double-T profile, the stem or the transverse T-leg of which can be suitably cut out to form tabs.
  • an angle profile for example an L-shaped steel profile with two legs can be used, at least one leg of which is held between the insulating glass panes.
  • the leg can protrude between the insulating glass panes so that it is quasi clamped between them—usually in a blocking—by an upper insulating glass pane resting on it and it resting on an end face of a lower insulating glass pane.
  • At least one tab described above can be formed projecting at right angles on it.
  • the steel profile offers a sufficiently rigid cross-section that is space-saving and relatively unobtrusive at the same time. In a corner of a building, particularly in a joint between a glass roof and a vertical glass wall, it can be incorporated almost invisibly.
  • two insulating glass panes can meet at a butt joint, with at least one of the insulating glass panes having a glass overhang of a single glass pane on its edge facing the other insulating glass pane.
  • the narrow face of the insulating glass pane can therefore have a (step) fold.
  • the glass overhang can be formed on an outside of the facade formed from them.
  • the glass overhang can cover a narrow longitudinal space in the area of the butt joint, in which the steel profile, its blocking and gluing and the like can be accommodated and thus optically concealed. From an outside, this can give the impression of a wider edge seal.
  • Structural interfaces to the steel profile can be provided from the inside, such as tie rods or pressure rods for connection or support to an abutment.
  • a glass overhang on both sides can enable a symmetrical design of the butt joint, which is optically particularly attractive for insulating glass panes that lie in the same plane.
  • the glass overhang of the insulating glass pane forming the roof glazing can not only cover the end face of the slide forming the vertical glass wall, but also protrude beyond it.
  • steel profiles of different quality can be used in the manner described above.
  • a rustproof steel profile is used, because this allows a high resistance to moisture and in particular to condensation water to be achieved.
  • stainless steel is maintenance-free in this respect.
  • the anchor according to the invention can be used in particular to absorb horizontal loads on an upper edge of the wall glazing.
  • the wall glazing can be supported on the roof glazing, for example to absorb wind pressure forces, while in the opposite direction, i.e. in the case of wind suction forces, it is held by the anchor.
  • a steel cable can therefore serve as an anchor in sections. Because in the load direction described above, essentially tensile forces occur that have to be transferred to an abutment.
  • a steel cable can be used in sections to divert it via the anchor, which offers another constructive and creative variant.
  • figure 1 shows a basic spatial sketch of a glass pavilion with a length of 8.6 m, a width of 5.8 m and a height of 4.2 m. It consists of a glazed steel frame construction 1 and two all-glass extensions 2 attached on both sides to the narrow sides of the steel frame construction 1.
  • the steel frame construction 1 represents an abutment to which the all-glass structures 2 constructed according to the invention are attached.
  • the ring anchor 14 is connected at both of its ends directly and additionally via two tension rods 40 in between to the steel frame structure 1 of the pavilion.
  • Horizontal loads on the roof glazing 10 such as wind pressure, snow and dead weight loads are carried in the area of the all-glass extensions 2 on three sides by the vertical wall glazing 12 arranged underneath. Solasten assumes a load-bearing bonding of the roof glazing panes 10 on the ring anchor 14.
  • the wall glazing 12 of the all-glass extensions 2 are for wind suction and wind pressure loads along their lower horizontal edge in a clamp construction, not explained in detail, and along their upper horizontal edge at the butt joint 50 over in the figures 2 , 3 tabs 143 described in more detail of the ring anchor 14 or stored on a blocking.
  • the roof glazing 10 is connected to the ring anchor 14 in the horizontal direction via a block and assumes a stiffening function of the U-shaped frame of the ring anchor 14 in the horizontal direction.
  • FIG 2 shows a section through a butt joint 50 of a roof-wall construction of an all-glass extension 2.
  • Its roof glazing 10 is designed as a pent roof, which meets the wall glazing 12 at the butt joint 50 and protrudes there with a projection 16 over the so-called high wall of the pent roof.
  • Both the roof glazing 10 and the wall glazing 12 consist of insulating glass panes or multiple-pane insulating glass.
  • the roof glazing 10 consists of a 10 mm thick pane 101 made of toughened safety glass (ESG), an adjoining pane space 102 of 12 mm, an 8 mm thick ESG pane 103, a subsequent pane space 104 also of 12 mm and a Pane package made of laminated safety glass made up of two partially toughened panes 105, 106 glued together, each with a thickness of 10 mm.
  • the gaps between the panes 102, 104 are each sealed on the circumference between the glass panes 101 and 103 or 103 and 105 that border them and have a peripheral edge seal 107 with a conventional width of at least 6 mm.
  • Each edge composite 107 is composed of a spacer 108 made of aluminum, the gluing and sealing 109 made of a two-component silicone elastomer between the adjacent glass panes 101, 103 or 103, 105 fixed and airtight.
  • a suitable adhesive is available under the name Dow Corning® 993, for example.
  • the roof glazing 10 has an end face 110 on the ridge side, on which the edge assemblies 107 and the panes 103, 105 and 106 terminate flush with one another. Only the toughened safety glass pane 101 projects beyond the end face 110 with the overhang 16 by 87 mm and thus gives a ridge-side edge region 11 of the roof glazing 10 a rebate.
  • the wall glazing 12 also consists of multi-pane insulating glass, which, viewed from the outside inwards, consists of a 12 mm thick ESG pane 121, an adjoining pane space 122 of 14 mm thickness, an 8 mm thick ESG pane 123, another pane space 124 of 18 mm and a laminated safety glass pane made of two glued together ESG panes 125, 126, each 12 mm thick.
  • the spaces between the panes 122, 124 are also maintained by edge bonds 127 made between the panes 121 and 123 and 123 and 125, respectively. They are also composed of spacers 128, described in more detail above, and an adhesive bond and seal 129.
  • the insulating glass pane 12 has an end face 130 on the ridge side, on which the panes 123, 125, 126 and the edge assemblies 127 terminate flush. Only the toughened safety glass pane 121 protrudes perpendicularly beyond the end face 130 by 61 mm, so that the wall glazing 12 also runs out at its upper edge 13 in a rebate.
  • the edge bond 127 of the wall glazing 12 on the inside of the building also has on the end face 130 a receiving pocket 131 made of anodised aluminum which is U-shaped in cross section and which is open towards the end face 130 . It is embedded in the non-load-bearing adhesive 129 of the edge seal 127, which is at least 12 mm wider than the edge seal 107.
  • the roof glazing 10 and the wall glazing 12 are at an angle of slightly less than 90° to one another, with the end face 110 of the roof glazing 10 lying in the rebate or over the end face 130 and there being approximately aligned with the space 124 between the panes.
  • the supernatant 16 of the roof glazing 10 is therefore not only on the end face 130, but also over the overhang 18 of the toughened safety glass pane 121.
  • the roof glazing 10 and the wall glazing 12 enclose an approximately L-shaped space with their folds and between the projections 16, 18 and the end faces 110, 130, which is sealed airtight and watertight on the outside by an adhesive joint 20 and on the inside by an adhesive joint 22 .
  • Two tabs 143 engage in the edge seal 127 of each individual insulating glass pane of the wall glazing 12, which is held on the ring anchor 14.

  • the vertical leg 141 is held in relation to the roof glazing 10 in the same way, in that a plastic strip 28 is wedged and glued between the end face 110 and the vertical leg 141 .
  • the plastic strips 26, 28 are only attached to those sections of the vertical leg 141 in which a tab 143 is arranged on the horizontal leg 142.
  • the projections 16, 18 carry cold foam insulation 30 and 32 on their respective insides, which run out towards the adhesive joint 20 to a round profile 34 made of polyurethane (PUR) that is undeformed only for drawing reasons.
  • PUR polyurethane
  • the annular anchor 14 runs horizontally and in a U-shape within the glass structure, encompasses the roof glazing 10 and is fastened to an abutment, not shown, at the free ends of its U-legs. Together with the roof glazing 10, the ring anchor 14 forms an immovable bracing plane.
  • the cut according to figure 2 runs through one of its U-legs.
  • figure 3 shows a section in the area of its transverse leg, namely in the area of a verge of the pent roof. Basically, here are largely the same Structural elements and their corresponding arrangement to one another, with the roof glazing 10 and the wall glazing 12 meeting at the verge at an angle of 90°.
  • the overhang 161 of the roof glazing 10 is made shorter, so that it ends flush with an outside of the wall glazing 12 .
  • a tie rod 40 is attached to the horizontal leg 142 of the ring anchor 14, which adjoins the horizontal leg 142 horizontally and thus in its extension and extends to an abutment, not shown.
  • the ring anchor 14 thus runs completely inside the butt joint 50 between the roof glazing 10 and the wall glazing 12. It is connected at its free ends to the abutment, not shown, and is also supported horizontally by the tension rods 40 running parallel to its U-legs.
  • the annular anchor 14 and its abutment consequently completely frame the roof glazing 10 on the peripheral side. It is thus mounted so that it cannot be moved horizontally and can therefore be used to stiffen the conservatory.
  • the annular anchor 14 transfers vertical loads from wind pressure, snow and its own weight, which act on the roof glazing 10, via the horizontal leg 142, which is blocked and glued to the strips 26, onto the panes 125, 126 of the wall glazing 12 arranged underneath. Wind suction loads on the roof glazing 10 are transferred to the ring beam 14 by the gluing of the roof glazing 10 in the area of the blocking.
  • both wind suction and wind pressure loads on the wall glazing 12 reach the inner edge bond 127 of the wall glazing 12, the receiving pocket 131 arranged there and the tab 143 glued therein ring anchor.
  • the ring anchor 14 forwards wind pressure forces via the strip 28 to the roof glazing 10, which is supported on the abutment. Wind forces, on the other hand, are transmitted directly to the abutment, not shown, by the ring anchor 14 either via the tension rods 40 or via its U-legs running parallel thereto.
  • the ring anchor 14 can be seen neither from an outside of the conservatory or its illustrated building edges nor from its inside. Because through the opaque Edge bond 127, 107 of the roof glazing 10 and the wall glazing 12 creates a "black frame" which is narrow and therefore inconspicuous in relation to the entire glass surface of the roof glazing 10 and the wall glazing 12. The meeting of the end faces 110, 130 and the overhangs 16, 18 at the butt joint 50 of the roof glazing 10 and the wall glazing 12 cover a barely recognizable space for the viewer, within which the ring anchor 14 is housed. As a result, the edge of the building where the roof glazing 10 and the wall glazing 12 meet is given a design that nevertheless appears slim and airy, without steel components being immediately recognizable. With the hardly impeded passage of light, the conservatory gives the impression of being made entirely of glass.
  • the figures 4 (Horizontal section) and 5 (vertical section) show a further embodiment of the invention using a vertically running butt joint 60 between two sets of insulating glass panes of a vertical wall glazing 12.
  • the structure of the sets of insulating glass panes corresponds to that according to FIG figures 1 and 2 .
  • two completely flat end faces 130 meet in the butt joint 60 , which are closed on the outside by an adhesive joint 20 and on the inside by an adhesive joint 22 .
  • In the butt joint 60 there are two edge bonds 127 opposite each other, namely two outer ones at the height of the pane spaces 122, at the height of which in the butt joint 60 a round profile 34 is also arranged.
  • a receiving pocket 131 is introduced in the manner described above, which in a bond 129 fastens a strip-shaped tab 145 as the anchor head of a T-shaped steel profile 144, which is welded to a plate-shaped anchor shaft 146.
  • the anchor shaft 146 protrudes approximately halfway into the butt joint 60 between the two end faces 130 and otherwise projects out of the butt joint 60 in the direction of an interior space.
  • There it forms a coupling section for a tie rod 40 which is attached to an anchor body 150 on an abutment, z. B. on a steel plate that is anchored in a concrete wall.
  • the second embodiment according to figures 4 and 5 consequently relates to a tie rod consisting of an anchor head, which is represented by the tabs 145 welded to the anchor shaft 146, and the anchor shaft 146, which enables a non-positive connection of the tension rod 40 as a tension element.
  • the vertical wall glazing can be achieved with the steel profile 144 as a ring beam 12 reliably supported in the horizontal direction on an abutment.
  • a U-shaped ring anchor could be formed in a horizontal butt joint with the steel profile 144.
