Definitions

  • the invention relates to a sealing arrangement for facades with a building-side support structure made of vertically extending post elements and horizontally extending transom elements and with flat panels which are attached to the front of the post and transom elements facing away from the building via respective sealing frames.
  • Building facades are increasingly being constructed as metal-glass structures.
  • these metal-glass facades have a metal frame, in which individual flat facade elements, such as glass windows and the areas between them, glass, but also metal, natural stone, artificial stone and plastic elements are used.
  • these facade elements are collectively referred to as panels. This is also because comparable constructions can also be achieved using wooden scaffolding and wooden panels.
  • solar collectors can also be used in such supporting structures.
  • the supporting structures consist in the usual way of vertically extending post elements and horizontally extending locking elements which form the cross bracing of the post elements with one another. According to the prior art, not only wooden supporting structures are known, but also those made of steel and aluminum. Hollow sections have also been used.
  • sealing frames which are applied to the front of the building, facing away from the post and transom elements, and on which the panels are then placed and connected to the supporting structure under pressure against the sealing frame.
  • the sealing frames are made from commercially available sealing elements by first cutting them to length and gluing them together. This is usually done at the factory and not on a construction site, since it can be assumed that a large number of sealing frames are required for a building.
  • the sealing frames must be attached to the supporting structure. The insertion into grooves in the supporting structure is conventional, but the production of supporting structures with grooves requires considerable effort.
  • Retrofitting of grooves is, for example, for steel support structures or not possible from hollow profiles. With supporting structures made of aluminum and wood, this is associated with considerable effort. In addition, even with careful manufacture of the sealing frame, it cannot be ensured that water pressed on by wind forces cannot nevertheless pass through.
  • the building facade is also subject to numerous other environmental influences, in particular wind forces, temperature, but also environmental noise. Furthermore, ventilation of the facade should be made possible where possible, which on the one hand protects the building itself and on the other hand prevents weather-dependent disadvantages in the cavity between the panels and the building. This is all the more so since the temperature conduction is of considerable importance for metal support structures. Wind forces are able to push water through even very small openings, which is definitely disadvantageous. After all, sound transmissions from outside the building or from the facade are extremely disruptive during construction work into the interior of the building and, if possible, to be prevented. It should be noted that the support structure, which is usually made of metal, has good transmission properties for sound waves when excited, for example by vibrations of the panels, i.e. only low structure-borne sound absorption.
  • Buildings of building construction in full skeleton construction are well known. Buildings where a facade is hung are also common. Both types of structures have in common that a building-side supporting structure is provided, which is composed of vertically extending post elements and horizontally extending locking elements, facade elements being attached to the supporting structure.
  • a building-side supporting structure is provided, which is composed of vertically extending post elements and horizontally extending locking elements, facade elements being attached to the supporting structure.
  • Such elements can be called panels. As is known, these panels are fixed to the supporting structure, but if possible they can be detachably attached.
  • FIG. 7 shows a horizontal extending locking element 1 in section and two insulating glazings as panels 2.
  • FIG. 10 also shows a supporting structure element, which, as shown, can either be a locking element 1 but also an unillustrated post element.
  • a grid-like arrangement is formed.
  • An arrangement is provided in which the individual panels, such as the insulating glazing 2, are to be firmly but releasably connected to the elements of the supporting structure such as the locking element 1 in a manner known per se.
  • this takes place in that a sealing arrangement 3 is provided between the edge of the insulating glazing 2 (as an example of a panel) and an edge-side support area of the locking element 1 as part of the supporting structure and both elements 1 and 2 are shown below as an example Means are pressed against each other.
  • the grid-like arrangement can be seen from FIG. 1.
  • a flat gasket 5 is initially applied over the entire surface of the front faces 4 of the various elements of the supporting structure that point away from the building, in the edge areas of which conventional sealing frames 6 and 7 are used for adjacent panels.
  • the flat seal 5 has, on the edge side, approximately dovetail-shaped grooves 8 in cross-section, wherein lips 9 can be provided in the bottom portion thereof.
  • the sealing frames 6, 7 are approximately T-shaped in section, the longitudinal legs 10 being essentially adapted to the cross-section of the grooves 8 and the transverse legs having lips 12 pointing outwards and cavities 13 extending through the entire sealing frame.
  • Lips 14 are likewise provided on at least one of the inwardly facing surfaces of the transverse leg 11, specifically on the side lying on the outside of the frame.
  • the flat seals 5 are first firmly attached to the front sides 4.
  • a type of attachment is described in more detail below.
  • the attachment can also be done by gluing.
  • the sealing frames 6 and 7 are then pressed into the grooves 8 of the flat seal 5 by inserting their longitudinal legs 10. Due to the inherent elasticity of the various sealing elements, in particular also the section 15 adjacent to the edge next to the grooves 8, the insertion of the sealing frames 6, 7 is possible without great difficulty.
  • the sealing frames 6, 7 themselves are usually already made from extruded material at the factory or in the factory, the corresponding joints being welded, glued or vulcanized to one another.
  • the flat gasket 5 can contain inserts made of heat-insulating and / or sound-absorbing and / or reinforcing material, glass fibers or carbon fibers being suitable for the latter, for example.
  • a cork insert 16 which is inserted in the section between the two grooves 8 of the flat gasket 5, is possible, for example, as the heat and sound-insulating material.
  • a completely embedded cork insert 16 is shown.
  • the rear side of the flat gasket as shown schematically in FIG. 7, can also be open, that is to say expose the insert 16 there and lie directly against the associated elements of the supporting structure, the locking element 1 in FIG. 7 .
  • Other materials are also conceivable, for example plastics such as polystyrene and the like, but also mixtures thereof. It is useful, however, that this insert 16 is already inserted in the flat gasket 5 at the factory.
  • a secure seal in the sealing joint can be achieved in the manner shown in FIGS. 3 to 5.
  • a dividing line 17 is shown in broken lines in FIG. 3, specifically there as a symmetrical, essentially dovetail-shaped representation.
  • a step-like overlap (not shown) or oblique overlap (also not shown) can also be provided.
  • an additional securing and sealing in the area of the dividing line 17 is advantageous. This is achieved by a sealing patch 18 completely glued in this area, specifically in the area between the two grooves 8 of the flat seal 5 via the dividing line 17.
  • the sealing patch 18 expediently contains flats 19 which run out all the way around the edge, as they do for example, in the case of repair stains for the repair of holes in bicycle tubes.
  • the flats 19 expediently extend very close to the grooves 8, in any case to the extent that after subsequent insertion of the sealing frames 6, 7, the lips 14 come to rest on these flats 19. This ensures that after the panels have been attached, even with an inaccurate cut or inaccurate arrangement of the various elements of the flat seal 5 in the region of the dividing line 17, the sealing effect is ensured, even if, for example, water is present under high wind pressure.
  • Fig. 1 shows this in supervision.
  • these crossing elements 21 can, for example, carry central reinforcing elements 22 which simplify their attachment.
  • they correspond to the longitudinal elements 20 and in particular have the cross section according to FIG. 6.
  • the panels for example the insulating glazing 2 are placed and pressed in a conventional manner in a fixed or detachable connection against the elements of the supporting structure with the sealing arrangement 3 being interposed. At no point is there a risk of a gap in the sealing arrangement 3, so that the ingress of water can be reliably prevented. Sound and / or thermal insulation can be achieved by means of the insert 16 mentioned.
  • FIG. 7 shows, in the manner already explained, a locking element 1 with a flat gasket 5 attached and sealing frames 6 and 7 inserted therein.
  • Insulating glazing 2 is placed there as panels.
  • the various sealing arrangements have not only elasticity towards and away from the building, but also in the direction transverse to it, without the sealing effect being lost.
  • a one-way valve 29 can be provided in the outer sealing arrangement 24, which valve allows water and / or air to escape from the space 28 to the outside, but prevents the entry of air from the outside.
  • the corresponding frame-shaped sealing element 27 has a plastic tube 30 on the vertically lower side of the outer sealing arrangement 24, on the outside of which, with regard to the building and the space 28, a tab 31 is partially attached and It is provided in part loosely that the closed state is predetermined in the normal state, taking advantage of the inherent elasticity, the flap 31 being deflected outwards at a certain pressure from the space 28, for example by heated and expanding air or by water, so that the valve opens , when the wind is blowing, the plastic tube 30 is closed by the tab 31.
  • a substantially rectangular tab 31 is provided. However, this can correspond to the cross section of the plastic tube 30 also have a different geometric shape.
  • One-way valves of this type are generally known, for example in bellows or
  • the screw connection 25 can now be a heat-conducting or, which is more disadvantageous, a cold-conducting bridge.
  • a bolt head 32 is provided outside the facade in the area of the strip 23.
  • the screw connection 25 penetrates both the strip 23 and the space 28 and the two sealing arrangements 3 and 24 and, as can be seen in particular from FIG. 10, enters the supporting structure, here the locking element 1.
  • a certain sealing effect in the area of the sealing arrangements 3 and 24 can indeed be achieved in that the corresponding opening for the passage of the screw connection 25 is made somewhat smaller than the diameter of the screw connection 25, so that there is an elastic contact, but the cold-conducting bridge is thereby not interrupted.
  • the screw connection is formed in two parts, namely on the one hand by a first part 33 used in the fastening of the internal sealing arrangement 3 and screwed into the supporting structure with an end threaded bore 34 and a second external bolt part 35 containing the bolt head 32 that after placing the bar 23 passes through it and is screwed into the threaded bore 34 of the first part 33.
  • the cold bridge remains.
  • the first part 33 of the screw connection 25 is formed in several parts.
  • a first element 36 and a second element 37 have mutually complementary spatial separating surfaces such that, as can be seen in FIGS. 10 and 11, in the assembled state, in which the axes lie on a common axis, which is also the common axis of the screw connection 25, the two elements 36 and 37 cannot be separated from one another in the axial direction, but can be guided apart or into one another in at least one direction perpendicular to the axis.
  • the parting plane can have a dovetail shape as shown in FIG. 10. It is also necessary that a non-rotatable connection is achieved for technical reasons.
  • the actual design and dimensioning of the first part 33 of the screw connection 25 and its two elements 36 and 37 is determined exclusively by static requirements. In the area of these dividing surfaces is advantageous for Interruption of the cold bridge, a corresponding thermal insulation layer 38 is introduced.
  • the two elements 36, 37 and the heat insulation layer 38 are firmly connected like an adhesive bond.
  • the advantage here is that the first part 33 of the screw connection 25 can be completely manufactured in the factory.
  • the panels such as the insulating glazing 2 are then attached and, by means of the strips 23 and the associated sealing arrangement 24, pressed against one another and against the elements of the supporting structure such that the bolt part 35 as the second part of the screw connection 25 into the associated threaded bore 40 of the first part 33 or whose first element 36 is screwed in.
  • sealing elements 26 and 27 of the outer sealing arrangement 24 also have cavities such as the cavities 13 of the inner sealing arrangement 3 or the sealing frame 6 and 7, as well as lips to improve the sealing effect.
  • the external sealing arrangement 24 can also have inlays like the internal sealing arrangement 3.
  • a sealing arrangement made up of simple elements which can be easily installed and nevertheless achieves a high sealing effect against environmental influences, in particular weather and sound influences.
