Pane holder in all-glass facades

The invention relates to a shuttering with a plurality of interconnected light weight Verschalungselementen for casting in particular walls or similar construction elements, each shuttering element being substantially tubular, thin-walled, is self-supporting and preferably flexible and wherein the shuttering elements are formed with openings, which in at least two, lying in (imaginary) planes, are arranged at an angle to each other offset element areas, which planes extend transversely to the longitudinal direction of each shuttering element.

The casting of, for example, foundations, load-bearing walls, walls, paths or Lanes or ceilings or Roofs of concrete or similar hardening filling materials with the help of shuttering elements in the form of wooden frames or Cladding is cumbersome and time consuming. Such formwork frames are heavy and unwieldy; they must be transported by crane vehicles and require binders, the necessary operations requiring the transportation, erection, removal, lubrication and storage of the frames.

Similarly, finished brick blocks and elements require extensive factory processing, costly transportation, laborious erection and intensive after-treatment.

The prior art can also be found in the following references: NO-46 428 C, DE-2 213 358 A1, DE-1 684 357 A, US-2 184 714 A, DE-C2-3 234 489, DE-A1- 3,727,956, WO-A1-82 / 04088, DE-A-1 812 590, DE-C2-3 003 446, SE-206 538 and FR-A-1 603 005.

The No-46 428 C refers to piling elements, which consist of hollow, connectable sections. In general, as a result of the formation of the connecting means of these known ramming elements, the ram elements when used as a shuttering only for casting of spaced columns or Piles are used; On the other hand, it is not possible to cast a continuous wall or or to allow reinforcement using horizontally and / or diagonally extending reinforcing bars. From this patent, however, it is known per se to use between adjacent portions or elements cooperating connecting means, which can be brought into a tight engagement with each other.

DE-2 213 358 A1 relates to a flexible, reinforced formwork wall which is not self-supporting but must be used in combination with suitable wood walls arranged at the ends and thus have substantially the same disadvantages as wood formwork frames.

DE-1 684 357 A relates to a flexible, reinforced and non-self-supporting shuttering wall which is divided into interconnectable sections which can be connected together by means of connecting means which can be brought into firm engagement with each other. This known shuttering system does not permit the casting of continuous walls and further prevents the arrangement of intersecting reinforcing bars.

US-2 184 714 A does not relate to formwork but refers to pre-reinforced concrete elements. In the use of such concrete elements or blocks for construction purposes, tie bars are used to hold adjacent concrete blocks in position in the finished structure.

The known structure according to DE-C2-3 234 489 and that of the above NO-46 428 C are similar to each other in many ways. In the embodiments shown, such a construction is not suitable for use as a shuttering.

DE-A1-3 727 956 discloses Veschalungselemente lightweight (weight) concrete, which are designed for bonding together. In many ways, these known and yet elongate elements correspond to the well-known above-mentioned concrete blocks.

WO-A1-82 / 04088 discloses methods of making constructions and includes remaining casing for casting concrete. The formwork elements are not self-supporting and the erected formwork structure is in practice a conventional, thick-walled formwork, which requires, inter alia, the use of ordinary binders.

DE-A-1 812 590 discloses components in which the entire formwork structure requires elements of different and different shapes. These differently shaped elements are held together by chucks, requiring the use of a very large number of loose parts.

DE-C2-3 003 446 relates to shuttering elements of the above-described block type and suffers from the same disadvantages.

In SE-206 538 there are disclosed hollow structural panels which have neither interconnected cavities defined by adjacent panels nor projecting interengaging connecting means for locking the relevant type.

The present invention has for its object to provide an accident-resistant disc holder while maintaining a good elongation compensation, in which the outer panes of a facade are sufficiently secured even at the highest changing wind loads against falling, without the attachment visually disturb the overall appearance of the all-glass facade.

This object is achieved by a disc holder of the type mentioned in the present invention that each of the two opposing, running on the length of the associated disc edge paragraphs a gap between the discs is assigned a holder, the fold extends substantially parallel to the disc plane and transverse to Disk plane is narrower than the height of the receiving outer shoulder pulley.

The fact that the holder leaves a gap between the discs, strains can be compensated. Rattling of the discs is prevented because the fold of the holder is parallel to the disc plane. Characterized in that the fold of the holder is narrower in cross-section than the height of the heights record heels of the outer panes, the remaining gap from the façade outside can be suitably covered.

If a single disc field is to be enclosed on all four sides by disc bumpers, it is expedient that the heels circulate on all four marginal edges of a disc field. The holder may be formed integrally on the edge length of each disc field continuously. Preferably, however, it consists of several on the edge length of each disc array spaced apart sections.

Preferably, the holder is resilient, so that any strains within a mounting gap of two adjacent disc fields can be easily collected. The holder may be made of a metal, or more suitably of a poorly heat-conductive material, in particular if the all-glass facade is to be designed wärmeisoiierend.

Preferably, the gaps of the holders receiving gaps between adjacent disc fields are closed on the outside by a cap or od with a sealing compound. Like. Covered. This is easily possible in the construction according to the invention, because after arranging the brackets in the paragraphs still enough space remains to cover the gap formed by the paragraph from the outside or fill.

Preferably, each disk array consists of a multi-layered laminated glass pane and the heels capture one or more of the façade exterior facing layers of the laminated glass pane. Laminated glass is known to be characterized by a high strength, because the individual layers of a composite disk package are bonded to each other over the entire surface and not as in the known insulating glass units, an adhesive bond only in the range of spacers or other brackets is effective.

Alternatively, each disc field can also consist of a single-layer, commercially available disc. In this case, the paragraph detects a façade outside facing partial cross-section.

In a preferred development of the invention, it is proposed that each pane panel consists of at least two spaced-apart individual panes comprising insulating glass unit, wherein the outer pane is a paragraph having laminated glass or single-layer disk. As a result, the invention can be used equally in insulated all-glass facades.

The invention is explained in more detail below with reference to various embodiments in conjunction with the drawing.

In the drawing, FIG. 1 a front view of a section of Ganzgiasfassade with several disc fields, Fig. 2 a cross section along the line ll-ll in Fig. 1 in the field of an extruded metal post profile and with holders consisting of sections, Fig. 3 a cross section corresponding to FIG. 2, but with a modified post support structure, Fig. 4 a cross section corresponding to FIG. 2 with support profiles running through the length of the disc edges, FIG. 5 a cross section corresponding to FIG. 4, in which the gap between two disc fields is filled with a rubber profile, Fig. 6 a cross section corresponding to FIG. 5, but with a modified, consisting of short pieces holding part, Fig. 7 a cross section corresponding to FIG. 6 with a support member passing through the edge length of the disk panels, FIG. 8th a cross section through a facade construction in which the Scheibenfeid consists only of a single multilayer laminated glass and Fig. 9 a cross section similar to FIG. 8, in which instead of a laminated glass pane, a commercially available single-layer glass pane is used.

The all-glass facade cutout shown in FIG. 1 has individual pane panels 1, 2, 3 which are arranged side by side and one above the other within the overall field in a common plane and fastened to a facade support structure 6 on their rear side. The facade support structure consists essentially of individual post profiles 5 and auxiliary profiles 6,7,8. Instead of the metal ones

AT 404 274 B

Post profiles 5 can find any other Befestigungsigunsarten for the support structure application, for.

B. steel frames 9 or a wooden frame 10, as is apparent from Figure 3.

Each disk array has peripheral edges 11 and an outer disk 12, 13 which according to the invention is stepped in cross-section at least at one of its circumferential edges 11. The paragraphs are labeled 14, 15 in the illustrated examples. The individual disc fields have at least two spaced apart from the outer plates 12, 13 individual discs 16,17 which form the inner facing the facade support structure facing slices and which together with the outer panes comprise an insulating glass unit. The outer plates 12, 13 and the inner discs 16, 17 are known to be glued together by spacers 18.

However, an all-glass facade construction according to the invention need not necessarily consist of insulating glass units, but it is also possible to allow the inner disks 16, 17 to fall away, as can be seen in FIGS. 8 and 9. In this case, the outer plates 12, 13 consist of a preferably multilayer laminated glass pane (Fig. 8) known to allow high mechanical stresses. Instead of a laminated glass pane, a commercially available single pane (FIG. 9), provided that it has a sufficiently high strength and other material properties, which allows processing of the (Jmfangskanten for the formation of paragraphs 14, 15, without there is a risk of disk fractures in a subsequent mechanical loading of the peripheral edges in a finished assembled disc field , It is important that the paragraphs 14, 15 are each arranged on the outer side of each outer pane, so that on the inside projections 19, 20 remain behind which can be engaged behind by a holder 21 and additionally mechanically stressed. The paragraphs are provided at the two mutually parallel vertical marginal edges 11 of each disc field when laterally coupled to a central disc array further disc fields. If, on the other hand, a single disc field is enclosed by adjacent disc fields all around, as shown in FIG. 1 shown, the paragraphs on all four edges to run around. The arrangement of the paragraphs is chosen so that the distance between the two adjacent projections 19, 20 of each frame field is less than the distance between the paragraphs 14, 15 having cross-sectional edge regions, so that in the gap 22 thus formed is sufficient space to the Receive brackets 21 and to arrange.

The brackets 21 each consist of individual profile strips 23, each of which has an outer bevel 24 which is narrower in cross-section than the height of the heel 14, 15 and the projections 19, 20 of the outer plates 12, 13 engages behind. The folds 24 are located at the ends of a central web of the profile strip 23, which extends transversely to the longitudinal plane of each disc array and rests against the peripheral edges. At their folds 24 opposite ends of the central webs have the brackets 21 each have a groove 25 bounding profile webs 26, 27, which serve to receive and attach the auxiliary profiles 6, 7 and extending substantially parallel to the disk plane. The profiled strips 23 may be designed as continuous strips running around the edges of the discs (FIGS. 2, 3, 4, 5, 7) but also consisting of a plurality of short pieces (FIGS. 6, 8, 9) arranged at a distance from one another on the disc frame edges. The short pieces are shown in dashed lines in the figure cross sections. The profile strips 23 may be integrally formed either with the U-profiles 26, 27 (Fig. 4, Fig. 5) or as a separate profile lengths with the U-profiles 26, 27 z. B. screwed, welded or connected in any other way (Fig. 2, 3, 8, 9).

Instead of the described design of the brackets 21, these can also be modified in the form, as shown in Figures 6 and 7. The brackets 28 shown there each consist of a cross-sectionally integral profile bridge with two equally long resilient legs 29, at their outer free ends are folds 30 which correspond to the folds 24 in the above-described first examples. In the base of the profile bridge 28 is a bore through which a screw 31 passes, which is bolted directly to the support structure 4. The profile bridges can also run on the edge lengths of the disc fields (Fig. 7) or as short pieces (Fig. 6) may be formed. As material for the brackets 21 and 28 used depending on the application metal or a poorly thermally conductive material, eg. B. Plastic.

For assembly, the individual disc fields are first assembled, d. h "tailored and the outer plates 12, 13 with the inner discs 16, 17 glued together via the spacers 18. Subsequently, the brackets 21 are placed on the edge region of each Scheibenfeides that the center webs 23 perpendicular to the disk longitudinal plane, while the folds 24 - the projections 19, 20 of the facade inside facing inner laminated glass layers 12 ', 13 * of the outer disks 12, 13 closely behind. In the example of FIG. 9 The inner laminated glass layers 12 ', 13' correspond to the inner cross-sectional areas 12, 13 of the single pane.

AT 404 274 Β

The fixation of the brackets 21 takes place by the respectively the disc 16 or 17 facing USchenkel 26 and 27 of the holder with the inner discs 16 and 17 are additionally glued at 32.

In this way, the respective outer disks 12, 13 and the inner disks 16, 17 of each

Disc field between the folds 24, 30 and the profile webs 26, 27 included and additionally glued, so that an absolutely solid composite is given for each disc field.

In the modified example according to FIGS. 6 and 7, in which profile bridges 28 are used as the mounting, the mounting takes place in a similar manner. There are also two individual disc fields initially set apart by a distance, then the profile bridge 28 is inserted so that the bends 30, the projections 19, 20 engage behind and finally made the final locking of the disc fields on the support structure 4 via the screw 31 and splice 32 , The respectively provided on the inside of the inner panes 16, 17 U-profile corresponds substantially to the legs 26, 27 having profile sections of the holder 21 in the example of Figures 2 to 5. These profile sections are also on the inner panes by adhesive layers 32 o. The like. attached and thus cause additional stabilization of the overall composite of the facade.

Finally, the gaps 22 formed in each case between two disk fields are produced, for example, by a cover tape 33 (FIG. 2) closed and sealed after the final assembly and all other remaining outer Sichtspalte with a silicone compound. The fact that the distance gap 22 is sealed from the outside and the folds of the brackets are thus not visible, the construction according to the invention from the outside a pleasing view. Of course, instead of the silicone composition, any suitable material can be used to fill in the gap, such. B. also a cap 33 '(Fig. 5) made of rubber or the like. The mounting of the disc panels in the examples of Figures 8 and 9 is carried out accordingly, since in these examples, only the inner panes 16, 17 are omitted with the spacers 18, which are common in conventional insulating glass units.
