Description

The invention relates to a support structure for insulating glass panes in particular for space-forming glazings such as conservatories, pavilions and the like. They are usually constructed of multi-pane insulating glass and comprise a steel construction that is as restrained as possible in order to minimize the "airy" and light-flooded impression of the glass structure.

The DE 2010 015 999 U1 relates to an arrangement with a roof-supported roof glazing, this and the side walls are made of glass panes and in which the support of vertical supports are held. The supporting beams each consist of strip-shaped, consisting of several glass panes laminated glass plates, wherein the connection between each support and a support by correspondingly shaped metal parts, which between two glass panes in a section of an intervening glass or by other metal parts between the two glass panes , An insulating glass plate forming the roof glazing and / or a side wall, are attached and glued to these. By the relevant metal parts, the mechanical connection of two glass plates is generated. However, the carrying capacity of this arrangement is limited.

The DE10 2013 217 600 A1 relates to a glass facade with internal support structure comprising at least one support element and at least two glass façade elements, wherein the glass façade elements are connected at at least one fastening edge with the at least one support element. The carrier element has two wings which are respectively engaged in laterally open spaces between the glass panes, wherein the carrier element and the glass facade elements are configured such that the carrier element is substantially completely enclosed by the glass facade elements in a plane perpendicular to its longitudinal extent. In the absence of anchoring the carrier element to a supporting structure beyond the glass panes, it should only serve to connect the glass panes with each other, but otherwise be largely insignificant statically.

The object of the invention is therefore to provide an all-glass construction for conservatories, pavilions or the like made of insulating glass panes, which has a high load capacity and the steel structure is still optically unobtrusive.

This object is achieved with a support structure according to claim 1. According to the invention, the support structure comprises a steel profile which can be mounted on an abutment and at least two insulating glass panes with an edge seal at their edges, with a butt joint between the insulating glass panes, the steel profile acting as an armature or at least as a partial section of an armature extends in the butt joint and parallel to the edges and engages with at least a portion in the edge bond of an insulating glass pane. An anchor in the construction industry is to be understood as a component which, due to its tensile strength, connects different and as a rule non-similar components to one another. For example, insulating glass panes of a glass front can be anchored to an independent building as an abutment made of steel or reinforced concrete. For example, wind pressure and suction forces acting on vertical insulating glass panes can be absorbed by the armature and removed at the abutment in order to ensure the stability of the glass front of, for example, a conservatory.

The construction according to the invention thus starts from an abutment such as a building exterior wall or a steel structure, to which it and in particular the steel profile adjoins. Thus, it does not represent a statically completely independent all-glass construction. The individual panes of their multi-pane insulating glazings consist of individual panes with an edge composite to which the individual panes are adhesively sealed and sealed airtight to form an evacuated or gas-filled space between the panes. Above all, the edge seal forms a narrow end face of an insulating glass pane. There spacers are glued between the individual panes, in addition to a defined distance to provide for a peripheral sealing of the space between the panes. Adjacent insulating glass meet each other at the butt joints, so that the edge bond of a first insulating glass pane comes to lie parallel to the edge seal of a second insulating glass pane. A butt joint can basically occur between two insulating glass panes, which lie largely in one plane. Unlike a scale impact, the insulating glass do not overlap on such a joint. A butt joint can also occur between two insulating glass panes, which are at an angle to each other. At a corner of the building, the angle is regularly 90 °, but it can differ both in the direction of higher values and in the opposite direction. At one corner, the insulating glass panes according to the invention overlap only on the front side of an insulating glass pane.

According to the invention, the steel profile runs essentially in the region 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. Already this allows the steel profile optically very restrained order. In addition, the steel profile engages with a section in the edge bond of an insulating glass to keep it from its narrow end face. Other than encompassing the insulating glass pane at its edge, the engagement of the steel profile in the edge bond represents a quasi "invisible" holding device of the insulating glass. The steel profile and its engaging in the edge compound section are "hidden" as it were in the butt joint or in the edge bond. Thus, the invention uses the already required edge bond of the insulating glass in addition to their attachment to the steel profile. Unlike a screw connection in the edge bond perpendicular to the window plane, no elaborate drilling through of a glass pane is required. Rather, the invention offers the possibility of both a linear and a selective retention of the insulating glass pane on the edge bond. Thus, it can be adapted to different loads with little design effort, for example by varying the distances of the sections in a punctual mount or by varying the length of the sections in a linear mount. Finally, for the connection to an abutment, the steel profile offers cutting or coupling points, as a rule at its longitudinal ends, with which it, for example, connects flush with the glass panes on the abutment or extends out of the butt joint of the glass panes.

According to an advantageous embodiment of the invention, the steel profile may form a ring anchor or at least a portion of a ring anchor. The ring anchor is an annularly closed component made of steel, which prevents falling apart of the converted or connected insulating glass panes by receiving a introduced into the insulating glass panes perpendicular to their plane of extension. If the ring anchor composed of individual sections, so the connections of the sections must be able to absorb sufficient tensile stress each other. In this respect, the ring anchor can be composed of the steel profile and an abutment, followed by the steel profile. The abutment can in turn in a steel structure or in a concrete structure which is steel-reinforced. In any case, the abutment complements the steel profile - not necessarily in geometric, but at least in static terms - to a ring.

In order to be as inconspicuous as possible, the cross section of the steel profile should be as slim as possible. Then, however, the steel profile - especially in a non-circular ring anchor - not be kink stiff enough to intercept horizontal forces, especially on longer flat glass fronts can. According to an advantageous embodiment of the invention, the steel profile can therefore have at least one coupling section for connecting a tension element orthogonal to its extension direction. The tension element can support the steel profile on the abutment or clamp it against the abutment. Alternatively, the tension element can also produce a support or tension on an opposite steel profile as part of the same ring anchor. The coupling portion is not located at the ends of the steel profile, but in the course beyond and beyond its ends to support the steel profile in a central region. Also several coupling sections are conceivable and useful. Because shortened by using a tension element a significant free support length of the steel profile and the steel profile can accommodate greater horizontal loads than its cross-section or its area moment of inertia alone allow the use of tension elements longer facades of insulating glass can build.

After an alternative to the ring anchor embodiment of the invention, the steel profile can form a tie rod of an anchor head and an anchor shaft. As an anchor head is the section of the steel profile to be understood, which is held in the edge bond of the insulating glass pane. The armature shaft forms a transverse thereto coupling portion of the steel profile, which allows a connection to a tension element. The anchor shaft thus provides a mounting surface for attachment of the tension element, so that it can ablate forces orthogonal to the extension direction of the steel profile on an abutment. In this case, the orientation of the armature shaft itself is of minor importance, as long as the tension element can be attached thereto in the power transmission direction of the armature.

The section of the steel profile, which engages in the edge bond, there is always to be permanently attached. It can be wedged, padded, locked or otherwise secured in the edge bond. According to a further advantageous embodiment of the invention, the portion of the steel profile is glued in the edge bond. This can be a sufficiently durable Attachment that can be made on site with a reasonable effort without the use of additional design means and without consideration of tight tolerances. As suitable adhesives, for example, silicone adhesives in 2-component technology are known. 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 allow cost-effective production of the components of the support structure according to the invention.

According to a further advantageous embodiment of the invention, the edge seal on a receiving pocket, in which the portion of the steel profile is glued or is. It may represent a separate component which is introduced into the edge bond, or 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 hand allow the definition of suitable adhesive partners, to which the adhesive can be tailored. Conversely, the arrangement of the receiving pocket allow a vote of their material regardless of the remaining material of the edge seal on the adhesive. The attachment of possibly separate receiving pocket on the edge bond can be done at the factory and thus with high quality, durability and reliability. In addition, the arrangement of a receiving pocket in the edge assembly 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 according to the static requirements. In addition, regardless of the dimensions of the edge composite always the same receiving pocket can be formed or used, which can be the same or repeatable conditions in the bonding he aimed at different dimensions of insulating glass panes or their edge compound. As a result, the bonding, in particular if it takes place on site, can be produced with high quality. Finally, a required or desired adhesive thickness can be set and the glue joint can be calculated more reliably.

According to a further advantageous embodiment of the invention, the receiving pocket can be formed as a glued into the edge seal U-profile. Thus, it forms a defined interface in the insulating glass pane for the integration of the section of the steel profile, which may be formed or loaded both linearly and selectively. The U-profile may be formed, for example, of aluminum or plastic, which means it with low Produce effort and integrate into the edge bond of the insulating glass with known technologies.

According to the invention, the steel profile binds with a section in the insulating glass pane or in its edge bond. In principle, the section of the steel profile can intervene linearly, for example with a profile limb, or selectively in the edge bond. According to a further advantageous embodiment of the invention, the portion may be formed as a tab which is integrally formed on the steel profile. It can be welded separately there or cut out of the steel profile. Thus, it defines a selective attachment of the steel profile, which can act linearly by a plurality of adjacent tabs. A point attachment can be advantageous in terms of the production of the bond, because it can provide shorter adhesive joints, a smaller adhesive surface and thus the advantage of a lower cost. It can also be structurally sufficient, for example, by engaging in only two places in the edge bond of an insulating glass pane.

The inventive engagement of the steel profile in the edge bond of the insulating glass transmits substantially forces in a direction perpendicular to the held insulating glass pane, usually Winddruck- and -sogkräfte. According to a further advantageous embodiment of the invention, the steel profile can be additionally held or fastened in the butt joint between the insulating glass panes. The holder can be linear or punctiform, for example, by a Verklotzen or gluing. As a result, a suitable, if possible, large-area power transmission, in particular of compressive forces between the insulating glass panes on the one hand, and the steel profile, on the other hand, can be achieved. With pressure forces, the holder can thus lead to a low surface pressure in the region of the edge seal of the insulating glass panes. A selective fixing can reduce the costs for the bond and its effort, achieve aeration or drainage between the adhesive points and thus avoid condensation. In any case, the steel profile can be better utilized statically by being acted upon in at least one other direction of force, namely in one of the two remaining spatial directions perpendicular to the plane of the insulating glass sliding, engages in the edge bond of the section of the steel profile. The steel profile itself can or only needs to be blocked (closed) between the insulating glass panes. With the supporting blockage of the steel profile and the bonding of its section in a marginal composite, an articulated and non-positive connection of two insulating glass slides can be achieved. As a result, the adhesive joints of the bond are exclusively through Normal stresses and shear stresses in the joint axis loaded, which benefits their durability.

The cross-sectional shape of the steel profile can be advantageously adapted to the particular installation situation, so that the steel profile remains optically unobtrusive. It may, for example, have a tube cross-section or a T or double T-profile, the stem or its transversely extending T-legs may be suitably cut out to form tabs. According to a further advantageous embodiment of the invention, an angle profile, for example, an L-shaped steel profile with two legs are used, whose at least one leg is held between the insulating glass panes. For this purpose, the leg can protrude between the insulating glass panes, so that it is quasi clamped between them - usually in a blockage - by an upper insulating glass on it and he rests on a front side of a lower insulating glass pane. At least one tab described above can be integrally formed at right angles. With an angular or L-shaped cross section, the steel profile provides a sufficiently rigid cross-section, which is at the same time space-saving and optically relatively inconspicuous. In a building corner, especially in a gap between a glass roof and a vertical glass wall, it can be integrated almost invisibly.

According to a further advantageous embodiment of the invention, two insulating glass panes can meet at a butt joint, wherein at least one of the insulating glass panes has a glass projection of a single glass pane on its edge facing the other insulating glass pane. The narrow end face of the insulating glass pane can thus have a (step) fold. Advantageously, the glass projection can be formed on an outer side of the facade formed from them. The glass supernatant can cover a narrow longitudinal space in the region of the butt joint, in which the steel profile, its blocking and gluing and the like can be housed and thus optically concealed. From an outside, this can give the impression of a wider edge bond. From the inside constructive interfaces to the steel profile can offer, such as drawstrings or push rods for connection or support on an abutment. A glass supernatant on both sides can allow a symmetrical formation of the butt joint, which optically offer particular in the case of insulating glass panes lying in the same plane. In insulating glass panes, which are at an angle to each other, and uneven Falzausbildungen the two adjacent insulating glass panes may offer. So can when forming a eaves of the glass supernatant of the roof glazing forming insulating glass cover not only the front of the vertical glass wall forming slide, but still survive on them.

Basically, steel profiles of different quality can be used in the manner described above. According to a further advantageous embodiment of the invention, a stainless steel profile is used, because this can achieve a high resistance to moisture and in particular to condensation. Unlike painted steel profiles, the paint layer of which can not be repaired faulty and with reasonable effort, stainless steel is so far maintenance-free.

The anchor according to the invention can in particular serve to receive horizontal loads on an upper edge of the wall glazing. In a direction pointing towards the abutment wall glazing can be supported, for example, to absorb wind pressure forces on the roof glazing, in contrast, in the opposite direction, so in wind suction forces, it holds the anchor. According to a further advantageous embodiment of the invention can therefore at least partially serve a steel cable as an anchor. Because in the load direction described above occur essentially tensile forces that must be transferred to an abutment. Their derivation via the anchor can take over at least sections of a steel cable, which offers a further constructive and creative variant.

FIG. 1 shows a 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 on both sides of the narrow sides of the steel frame construction 1 attached glassware 2 together. The steel frame construction 1 represents an abutment on which the all-glass structures 2 constructed according to the invention are shot. In joints 50 between the roof glazing 10 and the wall glazing 12 each has a horizontally arranged, lying U-shaped frame or ring anchor 14 of an angle steel profile. The ring anchor 14 is connected at its two ends directly and in between additionally via two tie rods 40 to the steel frame construction 1 of the pavilion. Horizontal loads on the roof glazing 10 such as wind pressure, snow and dead weight loads are removed in the area of the all-glass extensions 2 on three sides by the vertical wall glazing 12 arranged underneath. The wall glazings 12 of the all-glass extensions 2 are for wind suction and wind pressure along their lower horizontal edge in a clamping construction not further explained and along its upper horizontal edge on the butt joint 50 in the Figures 2 . 3 Lugs 143 described in more detail of the ring anchor 14 and stored on a blockage. The roof glazing 10 is connected in the horizontal direction via a blockage with the ring anchor 14 and assumes a stiffening function of the U-shaped frame of the ring anchor 14 in the horizontal direction.

FIG. 2 Its roof glazing 10 is designed as a pent roof, which meets at the butt joint 50 on the wall glazing 12 and projects there with a projection 16 on the so-called high wall of the pitch roof. Both the roof glazing 10 and the wall glazing 12 consist of insulating glass slides or multi-pane insulating glass. The roof glazing 10 is viewed from outside to inside of a 10 mm thick disc 101 made of toughened safety glass (ESG), a subsequent space between panes 102 of 12 mm, 8 mm thick tempered glass pane 103, a subsequent space between the panes 104 also 12 mm and a Laminated laminated safety glass pack consisting of two partially bonded discs 105, 106 glued together, each with a thickness of 10 mm, together. The space between the panes 102, 104 seals in each case a marginal composite 107 which extends circumferentially between the glass panes 101 and 103 or 103 and 105 surrounding it and has a conventional width of at least 6 mm. Each edge assembly 107 is composed of a spacer 108 made of aluminum, which fixes a bonding and sealing 109 of a two-component silicone elastomer between the adjacent glass sheets 101, 103 and 103, 105 fixed and airtight. A suitable adhesive is available, for example, under the name Dow Corning ^o 993.

The roof glazing 10 has on the ridge side an end face 110, on which the edge composites 107 and the disks 103, 105 and 106 are flush with each other. Only the tempered glass pane 101 projects beyond the end face 110 with the projection 16 by 87 mm and thus gives a ridge-side edge region 11 of the roof glazing 10 a fold.

The wall glazing 12 is also made of multi-pane insulating glass, which viewed from outside to inside of a 12 mm thick tempered glass pane 121, a subsequent space between the panes 122 of 14 mm thickness, an 8 mm thick toughened glass pane 123, another disc space 124 of 18 mm and a laminated safety glass of two glued together, each 12 mm thick tempered glass panes 125, 126 composed. The interpane spaces 122, 124 are also maintained by edge bonds 127 made between the disks 121 and 123 or 123 and 125. They also consist of spacers 128 described in more detail above and a bond and seal 129.

The insulating glass pane 12 has a front side 130 on the first side, on which the disks 123, 125, 126 and the edge connections 127 are flush. Only the toughened glass pane 121 protrudes vertically beyond the end face 130 with a protrusion of 61 mm, so that the wall glazing 12 also terminates at its upper edge 13 in a fold.

The building inner edge bond 127 of the wall glazing 12 also has on the end face 130 a U-shaped receiving pocket 131 made of anodized aluminum, which is open towards the end face 130. It is embedded in the non-load-bearing bond 129 of the edge bond 127, which is at least 12 mm wider than the edge bond 107.

The roof glazing 10 and the wall glazing 12 are at an angle of slightly less than 90 ° to each other, wherein the end face 110 of the roof glazing 10 lies in the fold or over the end face 130 and there approximately aligned with the space between the panes 124. The supernatant 16 of the roof glazing 10 is therefore not only on the front side 130, but also on the supernatant 18 of the toughened glass pane 121 over. The roof glazing 10 and the Wall glazing 12 include with their folds and between the supernatants 16, 18 and the end faces 110, 130 an approximately L-shaped space which is closed by an adhesive joint 20 on the outside and by an adhesive joint 22 on the inside airtight and watertight.

In the L-shaped space extends an isosceles L-shaped ring anchor 14 made of stainless steel with a vertical leg 141 and a horizontally extending leg 142. On its horizontal leg 142 vertically projecting tabs 143 are welded on the underside, which engage in the receiving pockets 131 and attached there by means of a bond 24. They represent a mechanical safeguard, in particular against wind suction. In each individual insulating glass pane of the wall glazing 12, which is held on the ring anchor 14, engage two tabs 143 in the edge seal 127 a. The horizontal leg 142 is padded between the end face 130 and the underside of the roof glazing 10 and glued to the above-mentioned adhesive of a two-component silicone elastomer. For this purpose, about 200 mm long plastic strips 26 made of polyoxymethylene (POM) respectively between the horizontal leg 142 on the one hand and the underside of the roof glazing 10 and the end face 130 on the toughened glass panes 125, 126 on the other hand wedged and glued there additionally supporting. In principle, the same way the vertical leg 141 is held against the roof glazing 10 by a plastic strip 28 between the end face 110 and the vertical leg 141 is clogged and glued. The plastic strips 26, 28 are in this case attached only in those sections of the vertical leg 141, in which a tab 143 is disposed on the horizontal leg 142.

Finally, the supernatants 16, 18 carry on their respective inner side a cold foam insulation 30 and 32, which expire on the adhesive joint 20 out on a purely illustrative reasons undeformed round profile 34 made of polyurethane (PUR).

The ring anchor 14 extends within the glass structure horizontal and U-shaped, includes the roof glazing 10 and is attached to the free ends of its U-legs to an abutment, not shown. Together with the roof glazing 10 of the ring anchor 14 forms an immovable stiffening level. The cut according to FIG. 2 passes through one of its U-legs. FIG. 3 shows a section in the region of his transverse leg, in the area of a curb of the pent roof. Basically, here are largely the same construction elements and their corresponding arrangement to each other, the Roof glazing 10 and the wall glazing 12 on the verge at an angle of 90 ° meet. In obvious difference to the design according to FIG. 2 is in FIG. 3 the projection 161 of the roof glazing 10 made shorter so that it is flush with an outer side of the wall glazing 12. In addition, a tie rod 40 is attached to the horizontal leg 142 of the ring anchor 14, which connects horizontally and thus in its extension to the horizontal leg 142 and extends to an abutment, not shown.

Thus, the ring armature 14 extends completely within the 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 also horizontally supported by the parallel to its U-legs extending tension rods 40. The ring anchor 14 and its abutment consequently frame the roof glazing 10 completely. It is thus stored horizontally immovable and can be used to stiffen the conservatory.

The ring anchor 14 are vertical loads of wind pressure, snow and dead weight, which act on the roof glazing 10, on the verklotzen with the strips 26 and glued horizontal leg 142 on the underlying discs 125, 126 of the wall glazing 12 from. Wind suction loads on the roof glazing 10 are transferred by gluing the roof glazing 10 in the area of the blocking with the ring anchor 14 to those.

Horizontal forces acting on the wall glazing 12, also receives the ring anchor 14: both wind suction and wind pressure loads on the wall glazing 12 reach over the inner edge bond 127 of the wall glazing 12, the receiving pocket 131 arranged there and the flap 143 glued therein ring beam. Wind pressure forces the ring anchor 14 passes on the bar 28 on the roof glazing 10, which is supported on the abutment. Wind pull forces, however, transmits the ring anchor 14 either via the tie rods 40 or via its parallel thereto U-legs directly on the abutment, not shown.

Neither from an outside of the conservatory or its illustrated building edges nor from its inside can be seen from the ring anchor 14. Because of the opaque edge bond 127, 107 of the roof glazing 10 and the wall glazing 12th creates a "black frame", which in relation to the entire glass surface of the roof glazing 10 and the wall glazing 12 narrow and therefore inconspicuous precipitates. Due to the meeting of the end faces 110, 130 and the supernatants 16, 18 at the butt joint 50 of the roof glazing 10 and the wall glazing 12, he obscures a barely recognizable space for the viewer, within which the ring anchor 14 is housed. As a result, the edge of the building at the meeting of the roof glazing 10 and the wall glazing 12 obtains a still slender and airy design without steel components being immediately recognizable. With the hardly obstructed passage of light, the conservatory gives the impression of being made entirely of glass.

The FIGS. 4 (Horizontal section) and 5 (vertical section) show a further embodiment of the invention with reference to a vertically extending butt joint 60 between two insulating glass packages of vertical wall glazing 12. The structure of the Isolierglasscheibenpakete corresponds to that according to FIGS. 1 and 2 , By way of derogation, two perfectly 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 are each two edge bonds 127 opposite each other, namely two outer at the height of the disc spaces 122, at the height in the butt joint 60 also a round profile 34 is arranged. In the inner edge joints 127 at the level of the space between the panes 124, a receiving pocket 131 is inserted in the manner described above, which fixes in a bond 129 a strip-shaped tab 145 as the anchor head of a T-shaped steel profile 144, which is welded to a plate-shaped armature shaft 146. The armature shaft 146 protrudes approximately halfway into the butt joint 60 between the two end faces 130 and protrudes from the butt joint 60 in the direction of an interior. There it forms a coupling portion for a pull rod 40 which is attached to an anchor body 150 at an abutment, for. B. on a steel plate which is anchored in a concrete wall.

The second embodiment according to the FIGS. 4 and 5 thus relates to a tie rod from an anchor head, which represent the tabs 145 welded to the armature shaft 146, and the armature shaft 146, which enables a frictional connection of the tension rod 40 as a tension member. With the steel profile 144 as a ring anchor, the vertical wall glazing 12 can be reliably supported in the horizontal direction on an abutment. In comparable Way could be with the steel profile 144 form a U-shaped ring anchor in a horizontal butt joint.

As the foregoing constructions described in detail are exemplary embodiments, they may be modified in a conventional manner to a wide extent by those skilled in the art without departing from the scope of the invention. In particular, the concrete embodiments of the ring anchor can be made in other cross sections than in the described here. Likewise, the folds of the roof and wall glazing can be configured in another form, if this is necessary for design reasons or designerischen reasons. Furthermore, the use of the indefinite article "a" or "an" does not exclude that the features in question may also be present several times or more than once.
