Description

The present invention relates to a sole bench receiving system. The invention further relates to a building facade and a building, each containing this base bench mounting system. In addition, the invention relates to the use of the bench seat receiving system for the production of window or door openings. Finally, the invention relates to a composite thermal insulation system for the insulation of external facades, comprising the base bench mounting system.

The document DE 20 2014 008 247 U1 discloses a sealing device for sealing a window frame in the lower region of a wall opening, the sealing device having first, second and third sealing surfaces which are designed to seal against an underside, an outside and a longitudinal edge side of the window frame with the interposition of at least one seal. In this way, the problem of sealing a window frame in the lower corner area of a wall opening with predictable sealing success should be resolved consistently and permanently. In this case, the bench support section can be offset in a step-like manner with respect to the support section in order to accommodate a stone or aluminum window sill which runs in under the window frame and is overlapped by it. According to the DE 20 2014 008 247 U1 a stone window sill run in smoothly under the window frame, while an aluminum window sill generally has a holding rib on the inside end that can be held in a first or second groove in a window frame profile on the underside. Here, the step section can connect on the inside to a support section and form a support surface for an inside window sill. Furthermore, the DE 20 2014 008 247 U1 that a bench support section can connect to the outside of the support section and laterally to a first side section in the transverse direction. According to the DE 20 2014 008 247 U1 the top-side contact surface of the bench support section can be offset in a stepped manner downward from the first sealing surface of the support section, so that a window sill to be arranged on the bench support section is partially covered by the window frame when the Window frame is sealed against three sealing surfaces as intended. The contact surface has to fall off to the outside so that water can drain off to the outside. Water damage to building facades can still be observed relatively frequently in the area of window and door openings. This is partly due to the fact that there is currently no inherently watertight connection between the window and the windowsill. Rain and condensate water can be found in the area of window and door connections, and in particular in the area of window and floor sills, where it is possible to penetrate the masonry or plaster layers via joints or support or collection surfaces. In addition to a visual impairment, this is often accompanied by damage to the building fabric and a reduction in the insulation properties.

By using thermal insulation composite systems to insulate exterior facades, constructive special paths often have to be followed in order to install window sills in such a way that the penetration of moisture can be prevented. This also applies in particular to the integration of window or base sills in external facades which are subsequently provided with a thermal insulation composite system.

Water damage in the area of window openings can also be caused by the fact that moisture, for example in the event of driving rain, can get into the frame profile via the space between the window pane and the seal. If no suitable drain openings are provided, the accumulating amount of liquid often escapes along side profile openings. Regardless of how the water escapes from the profile frame, this regularly leads to water damage to the masonry or the building facade.

The mounting systems known from the prior art for the installation of window or sole banks also harbor the risk of water ingress via joints. So-called water can also occur. This harbors the risk of frost damage in particular. The sole bank is therefore regularly used as protection against the ingress of water.

It has been shown that the measures known from the prior art for the tight installation of sole banks have weak points, for example lead to inadequate coverage of the endangered areas. The systems known from the prior art consequently provide entry points for rainwater even when all construction measures are carried out correctly.

The present invention was therefore based on the object of providing a system with which the occurrence of water damage in the area of window sills can be effectively prevented and which can be installed simply and reliably.

The invention solves this problem with a sole bench receiving system which contains at least the features of claim 1. Accordingly, a sole bench receiving system has been found, comprising a sole bench receiving unit comprising a front side, a rear side and an upper side as well as a first lateral boundary of the upper side and optionally a, in particular opposite, second lateral boundary of the upper side. When the sole bench receiving unit is used in a generic manner, this upper side has a drain surface which is inclined downwards in the direction from the rear to the front or is formed therefrom. The sole bench receiving system according to the invention further comprises a first sole bench guide in the area of the first lateral boundary of the upper side and optionally a second sole bench guide in the area of the second lateral border of the upper side, and a support area for a profile frame, in particular window or door frame, which is located on the rear side Connects the top of the sole bank receiving unit. According to a first embodiment variant, the sole bench receiving system according to the invention further comprises at least one first waterproof layer comprising a rear edge, in particular in the form of a film, on or on the top of the sole bench receiving unit and at least in sections, in particular over the entire area, on or on the support area. According to a second embodiment variant, the sole bench receiving system according to the invention comprises at least one second waterproof layer comprising a rear edge, in particular in the form of a film, on or on the top of the sole bench receiving unit and at least one further waterproof layer (third waterproof layer) comprising a front edge, in particular in the form a film, at least in sections on or on the support area, which forms an overlap area with the second watertight layer in such a way that when the sole bank receiving system is used in a generic manner, the rear edge of the second watertight layer below the front edge of the third watertight layer, in particular sealingly with it connected, exists. According to a third embodiment variant, the sole bench receiving system according to the invention comprises at least a fourth watertight layer, in particular film, comprising a rear edge with a first section on or on the top of the sole bench receiving unit and a subsequent second section arranged and designed for, in particular adhering, attachment a profile frame. The sole bench receiving unit comprises, for example, or represents such a parapet parapet, such as window parapet. The sole bench receiving system according to the invention preferably represents a window ledge receiving system.

In an expedient refinement, it is provided that the sole bench receiving system according to the invention also contains a sole bench profile which, in the transition from the upper side to the front side of the sole bench support unit, lies against a section of the upper side and the front side, in particular flush. With the aid of such a bank profile, it is also possible to ensure in a particularly effective manner that liquid accumulating on the upper side runs off, it also being possible for this liquid not to run directly along the building facade, but at a distance therefrom.

Furthermore, it can be provided in an advantageous embodiment that the sole bank profile comprises a first and a second leg, the first Leg abuts at least in sections on the top side and the second leg at least in sections abuts the front of the sole bank receiving unit.

Such a bench seat receiving system is also preferred, in which a section adjoins the first leg of the bench bench profile, which protrudes beyond the section lying on the front side and in particular comprises a drip nose. This configuration allows a particularly safe drainage or drainage of water without deposits or color changes on the outer facade.

In the case of the second embodiment variant of the sole bench receiving system according to the invention, it can be provided in an expedient embodiment that the third waterproof layer extends into the region of the inclined surface of the upper side. The overlap with the second watertight layer or the overlap area of the second and third watertight layer can be present on the inclined surface of the top side or on the support area or in the transition area from the inclined surface of the top side and the support area. The support area is generally oriented essentially horizontally, but can also, in particular only slightly, be inclined downwards in the direction of the front side.

Particularly suitable sole bench mounting systems according to the invention are also distinguished by the fact that the first sole bench guide comprises a first sole bench guide profile, in particular sole bench guide plug-on profile, and / or that the second sole bench guide comprises a second sole bench guide profile, in particular sole bench guide insert profile. As a result, coatings, for example plaster coatings, can be brought up to the bottom bench guide in a particularly pragmatic and reliable manner.

Furthermore, it can be provided that the first or the second waterproof layer covers the top extension of the sole bank profile, at least in sections, in particular completely. The complete cover ensures that water at any time cannot penetrate into the building structure.

In a further expedient embodiment, the sole bench receiving system according to the invention further comprises a first reveal in the area of the first lateral boundary of the Top of the sole bench receiving unit and / or a second reveal in the area of the second lateral boundary of the top of the sole bench receiving unit.

In the sense of the present invention, in a further embodiment, the sole bench receiving system also includes a sole bench designed and designed to be attachable, in particular reversibly, in the first and second sole bench guides. For example, a sole bank can be a window sill. It regularly represents the lower end of a window or door opening. Suitable base or window sills can be made of stone, composite material, metal or the like.

The sole bank can be connected to the sole bank receiving unit, for example, by means of so-called adhesive beads which are attached to the top of the sole bench receiving unit or the waterproof layer thereon. In this way, the sole bench does not come into direct contact with the sole bench receiving system according to the invention. For the adhesive beads, for example, adhesive compositions based on acrylic resins or based on polyurethanes can be used. As a rule, a large number of adhesive beads are attached to each bank of the sole. These usually run in the direction from the rear to the front of the sole bench receiving unit and can, for example, have an average lateral distance from one another in the range from 10 to 30 cm. Since the adhesive beads are not arranged essentially continuously parallel to the front side of the sole bench receiving unit, but rather run in the direction from the rear to the front side of the sole bench receiving unit, water that is produced can easily reach the front side via the inclined surface of the upper side between adjacent adhesive beads and there, preferably via a sole bank profile, drain. With the help of the adhesive beads, a distance between the underside of the sole bench and the waterproof layer in the range of, for example, 5 mm to 20 mm can easily be set. Often the material used for the adhesive beads is one that has a certain elasticity. So it can happen that with an adhesive bead with a height of about 10 mm after laying the sole bank, the distance between the underside of the sole bank and the upper side of the sole bank receiving unit is in the range of 5 to 8 mm. The sole banks that can be attached to the top of the sole bench receiving unit with the aid of the adhesive beads can be mounted in the inventive sole bench receiving system in such a way that there is no direct contact with the first and / or the second sole bench guide comes about. This also helps to prevent moisture damage.

With the sole bench receiving system according to the invention, it is possible to create a construction which is set up and designed such that the sole bench predominantly has no contact with the upper side or the first or the second waterproof layer and particularly preferably no contact at all with the upper side or the first or the second waterproof layer.

With the sole bench mounting system according to the invention, such embodiments are also detected which furthermore have a profile frame, in particular window frame, with a lower profile frame edge which is present at least in regions above the first or third waterproof layer. In this case, those systems are preferred in which the profile frame, in particular the lower edge of the profile frame, is designed and set up in order to direct water present in the profile frame to the first or the third watertight layer. This is achieved, for example, by the fact that the lower edge of the profile frame has outlet openings on the underside or lateral outlet openings. The above-mentioned embodiment is particularly useful for plastic windows, i.e. in the case of windows or doors containing glass panes embedded therein, for example patio or balcony doors, which are based on a plastic profile. Because here in heavy rain, e.g. Driving rain, moisture get past the seal into the hollow profile frame. With the aid of the sole bench receiving system according to the invention, this moisture can be removed safely and in a targeted manner without damage to moisture or water occurring.

The sole bench mounting system according to the invention also allows it to be integrated into thermal insulation composite systems or to be part of the same. Accordingly, in an expedient embodiment, the base bench receiving unit, the first reveal and / or the second reveal can comprise or represent an insulating material, preferably containing a plate or made of foamed insulating material or containing or made of fiber insulating material, in particular fiber insulating material. Furthermore, in a further preferred embodiment, the sole bank receiving unit, the first reveal and / or the second reveal, preferably an integral part of a composite thermal insulation system.

For example, foamed plastic materials with a density of 120 kg / m ³ or more can also be used for this.

In particular for the third embodiment variant of the sole bench receiving system according to the invention, it has proven to be advantageous to additionally set up a sealing closure for the at least partial receiving of the sole bench guide comprising a watertight layer with a first section and designed for contact with the first section of the first, second or fourth layer, one second section set up and designed to bear against the lateral boundary and a third section set up and laid out to bear against the second section of the fourth layer or to provide a profile frame. The sealing closure is preferably carried out essentially in one piece.

The object on which the invention is based is accordingly further achieved by a building facade or a building containing at least one sole bank receiving system according to the invention. The sole bench receiving system according to the invention is particularly suitable for the production of window or door openings.

Furthermore, the object is achieved by a sole bench guide unit, which is not part of the invention, comprising which can be oriented essentially horizontally when the sole bank guide unit is used in a generic manner and which has at least one groove, and b) a plaster extractor profile with an essentially L-shaped configuration corresponding to the L-shaped configuration of the sole bench guide comprising a first leg, which when the sole bank guide unit is used in a generic manner is essentially vertically orientable, and a second leg, which is essentially horizontally orientable when the generic type of sole bank guide unit is used and contains at least one spring for engaging in the at least one groove of the second leg for connecting the plaster extractor profile to the sole bench guide.

In a suitable embodiment, the sole bench guide unit is characterized in particular by the fact that the first leg of the sole bench guide has at least one groove and that the first leg of the plaster extractor profile has at least one tongue, designed and set up to engage in the at least one groove of the first leg to connect the Plaster deduction profile with the sole bench guide.

Accordingly, it is possible with the present invention to provide a sole bank receiving system with which window or sole banks can be installed without having to have any contact with the ETICS system or an ETICS coating. This is accompanied by the further advantage that material expansion occurring in the event of a change in temperature, whether in the ETICS system or in the case of the base banks, does not lead to damage and thus does not lead to an increase in the risk of moisture or water damage.

With the present invention, the window or sole bench assembly can be carried out both before and only after the application of a plaster coating, for example of the plaster and top plaster, which may also contain a fabric reinforcement. Accordingly, the base bench mounting system according to the invention is suitable for use in new buildings as well as for repair or refurbishment measures in existing buildings. With regard to effective thermal insulation, it is also advantageous here that the window and sole banks installed in this way can be completely decoupled from the composite thermal insulation system. This further reduces the risk of thermal bridges. This procedure also has process engineering advantages. Window and floor sills can also be exchanged or exchanged at a later date as desired, without damaging any existing thermal insulation composite system or a coating belonging to this system.

On this second leg 33 can, as in Figure 4 shown, a reinforcing fabric can be attached, which covers the front side 4 at least in regions. The reinforcing fabric of the sole bank profile 29 is usually embedded in a plastering during the cleaning work. Furthermore, the sole bank profile 29 has a section 35 which projects beyond the section 33 resting on the front side 4. The waterproof layer 20 also lies on this section. Water dripping from this section does not come into direct contact with the front 4.

Figure 5 shows a further development of the embodiment of the sole bench receiving system according to the invention Figure 4 . The sole bench guide 16 is inserted into the recess 44 and by means of adhesive, for example hybrid adhesive, with the side wall and over the first leg 48 has been connected to the waterproof layer 20. The sole bench guide profile 30 is connected, preferably by means of gluing, to the sole bench guide 16 or inserted therein. In the embodiment shown, the sole bench guide profile 30 is a sole bench guide clip-on profile. Such a sole bank guide profile can, as in Figure 5 shown can be used as a so-called plaster extraction profile 54. On the back of the horizontal leg 55 of the sole bench guide profile 30 there is a tongue (not shown) which fits into the groove 56 of the second leg 52 of the first sole bench guide 16 (see Figure 1 ) intervenes. A particularly strong connection can be obtained by providing the tongue and / or groove with an adhesive before joining them together. This in Figure 5 Shown bench guide profile 30 or plaster deduction profile 54 also has a reinforcing fabric 59, which, as in Figure 5 shown, can be in the form of a so-called diagonal reinforcement. In a preferred embodiment, this reinforcing fabric can already be connected at least in sections to the legs of the sole bench guide profile. The reinforcement fabric attached to the base rail guide profile can be embedded in, for example, a flush-mounted plaster during the plastering work. A sole bench, for example a window sill, can be introduced into the sole bench guide 16 in such a way that it does not come into contact with the first watertight layer 20 and the second watertight layer 26.

With the sole bench mounting systems according to the invention shown in the figures, a very effective structural sealing measure is provided in the area of windows and balcony doors.
