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 facing away from the building front of the post and transom elements 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, if possible, ventilation of the facade should be made 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
  • Rule structure made of metal when excited, for example by vibrations of the panels, has good transmission properties for sound waves, i.e. only low structure-borne sound absorption.
  • FIG. 1 is a top view of a section of a facade with the panel removed and part of the sealing arrangement
  • FIG. 2 shows an enlarged part of the sealing arrangement in the crossing area of the supporting structure
  • FIG. 4 shows a cross section in this area
  • FIG. 5 shows a longitudinal section in this area
  • FIG. 8 shows a one-way valve for use in the invention
  • FIG. 9 shows the one-way valve according to FIG. 8 in a view from below
  • FIG. 11 shows the fastening element according to FIG. 10 in a side view.
  • 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 support structure is provided, which is composed of vertically extending post elements and horizontally extending transom elements, facade elements being fastened to the support structure.
  • a building-side support structure is provided, which is composed of vertically extending post elements and horizontally extending transom elements, facade elements being fastened to the support 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 are essentially adapted to the cross section of the grooves 8 and the transverse legs outwardly facing lips 12 and 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 as a whole.
  • 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 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.

Abstract

L'invention décrit des dispositifs isolants pour façades qui, tout en étant faciles à fabriquer et à monter, assurent une isolation fiable contre les influences de l'environnement telles qu'intempéries et bruit. Selon un mode de réalisation, un dispositif intérieur d'isolation (3) est composé d'un joint plat (5) pouvant être fixé à l'ossature, sur lequel peuvent être installés des châssis isolants (6, 7) classiques. Les jointures entre les éléments (20, 21) du joint (5) peuvent être étanchéifiées par des pièces isolantes (18) collées sur lesquelles les châssis (6, 7) peuvent coulisser. Dans un dispositif extérieur d'isolation (24), qui peut avoir la même structure, sont prévus des clapets anti-retour (29) pour évacuer l'eau et l'air mais également pour empêcher la pénétration d'influences de l'environnement. Les extrémités d'un raccord à vis (25) exposées aux influences de l'environnement et les extrémités dudit raccord à vis introduites dans l'ossature sont séparées par une couche d'isolation thermique (38) placée entre des éléments contigus (36, 37) du raccord à vis (25), ces éléments (36, 37) étant solidaires en rotation et liés axialement de façon inamovible.
