Description

The invention relates to an on-board profile for mounting a window sill, in particular an outer sill, wherein the on-board profile has an angle section with a first leg and a second leg attachable to the masonry of a soffit, wherein the first leg on its upper side at least one support designed as a projection for the sill has, and wherein at the top of the first leg at least one, extending along this sealing lip is arranged, which protrudes normal to the plane defined by the first leg plane over the at least one support, and wherein the legs of a first plastic and the sealing lip The invention also relates to a kit for thermally insulated installation of a sill in a provided for a window wall breakthrough of a building, the kit a left and a right side profile of the aforementioned Ar t.

Such, also called on-board profile board profile is off AT 004 959 U1 known. It has an angle made of hard PVC angle profile having a first and a second leg, which are connected to each other in an L-shape. The first leg is narrower than the second leg and is mounted for mounting the sill on an inclined surface of a Dämmkeils, which is arranged at the bottom of a wall breakthrough for a window that the inclined surface from the window to the building outside drops. The insulating wedge consists of a heat-insulating material and is intended to thermally insulate a windowsill to be mounted on the insulating wedge against the building wall. The second leg is arranged so that it faces a window sill.

To support the sill, the first leg on its upper side on two web-shaped supports, which are parallel to each other and parallel to the second leg. The supports are configured as projections which project upwards in relation to a surface region of the first leg located between them. In a depression formed between the supports is an insert arranged, which has a plurality of parallel to each other and parallel to the second leg extending sealing lips made of a second plastic, which is softer than the first plastic When the sill rests on the supports, the sealing lip comes to rest on the underside of the sill.

From practice also a generic extruded profile is known, which has an angle profile made of aluminum. The angle profile has an L-shaped cross-section with a first and a second leg arranged at right angles thereto, which is welded to a longitudinal edge of the first leg. The first leg is wider than the second leg and is mounted for mounting the sill on an inclined surface of a Dämmkeils, which is arranged at the bottom of a wall breakthrough for a window that the inclined surface from the window to the building outside drops. The insulating wedge consists of a heat-insulating material and is intended to thermally insulate an aluminum window sill to be mounted on the insulating wedge against the building wall. The second leg is arranged so that it faces the masonry of the soffit, which is arranged on the side of the wall breakthrough on which the connection profile is mounted on the Dämmkeil. At its front end facing the window sill, the on-board profile has an end wall which is screwed onto the window sill during assembly of the on-board profile. The end wall is arranged at right angles to the plane of the second leg. The end wall is integrally connected to the second leg and welded to the front end of the first leg.

To support the sill, the first leg has on its upper side a plurality of web-shaped supports which run parallel to one another and parallel to the second leg. The supports are designed as projections which project upwards relative to a laterally adjacent surface region of the first leg. Adjacent supports have mutually facing side walls, in each of which a parallel to the longitudinal axis of the board profile groove is recessed. In the grooves, a rubber sealing lip is used, which projects beyond the supports normal to the plane defined by the first leg. When the window sill rests on the supports, the sealing lip comes to rest on the underside of the sill. Between the sealing lip and the second leg, a channel is formed under the windowsill, through the rainwater, which, for example, when they occur come from driving rain on the soffit under the windowsill, can run to the remote from the window floor front end of the board profile. In general, the board profile is installed so that it protrudes with its front end over the outer surface of the building wall. The supernatant measure (drip edge distance) is chosen so that rainwater and / or contaminants therein, such as dust, pollen or the like, which flow off via the on-board profile, do not come into contact with the building wall.

Since the metalworking tools required for cutting the on-board profiles to the required length are usually not available on the construction site, the on-board profiles made of aluminum are usually delivered to the construction site by the supplier in a predetermined length. Then they are mounted there by mechanics on the window sill.

However, due to manufacturing tolerances that may occur during the construction of the building, it may happen that the board profiles are shorter or longer than the length required to achieve a correct projection size, in which case it may happen that the front end of the board profile is not or not protrudes far enough beyond the outer surface of the building wall, so that over the board profile rainwater flowing out of contact with the building wall and where it can cause contamination, such as dark streaks.

The prior art board profiles also have the disadvantage that the sealing lips must be used during assembly between the grooves provided on the supports. This is associated with an increased time and effort.

It is therefore an object to provide an on-board profile and a kit of the type mentioned, which are inexpensive to produce in which the on-board profile and can be tailored in a simple manner in the required length on a construction site.

According to the invention this object is achieved in an on-board profile of the type mentioned in that the first plastic is integral with the second plastic composites.

Advantageously, this makes it possible to tailor the on-board profile on a construction site with a knife, pliers, edging shears, saw or the like to the required length. As a result, the installer, who may be a painter or a plasterer, for example, adjust the length of the board profile on site to the respective extent of the wall breakthrough. This ensures that the on-board profile is always mounted with the correct projection to the outer surface of the building wall or a heat insulation applied thereto. Since the board profile is made of plastic, it allows a heat bridge-free installation of the windowsill. During mounting, the on-board profile is preferably adhesively attached to the soffit, to the window sash and / or to an insulating wedge located below the on-board profile. By this measure, thermal bridges, as e.g. can occur when bolted to the window sill board profiles are avoided. After the on-board profile has been mounted on the left and right reveal of the wall breakthrough, the window sill can be inserted between the on-board profiles. It can be slid on the supports.

The on-board profile according to the invention is preferably designed as an extrusion profile. It can be produced inexpensively by coextrusion, ie by bringing together different plastic melts , SK adhesives and then extruding the merged melts through a profiled nozzle.

It is advantageous if the first plastic is a thermosetting plastic and the second plastic is a thermoplastic elastomer. Due to the thermosetting plastic, a stable support of the sill is made possible, for example, on a Dämmkeil. The thermoplastic elastomer allows a good seal of the board profile against the underside of the windowsill.

Preferably, the sealing lip is spaced from the second leg. When installed, a channel is then formed between the sealing lip and the second leg, can be removed through the rainwater, which flows, for example, in driving rain on the soffit and passes under the windowsill, to the front edge of the windowsill.

In an expedient embodiment of the invention, the sealing lip is web or strip-shaped and extends in a plane which is inclined relative to a plane defined by the second leg vertical plane. If the sill is inserted into the on-board profile, the sealing lip can then tilt in a defined direction to the side. It is pressed elastically to the underside of the windowsill. Due to its web-shaped or strip-shaped configuration, the sealing lip can be produced by co-extrusion together with the angle profile.

In a preferred embodiment of the invention, the at least one support web-shaped or strip-shaped and extends parallel to the second leg. The support then allows a uniform, linear support of the sill. In addition, it can be molded directly to this during the extrusion of the angle profile.

In an advantageous embodiment of the invention, the support has at least one side facing the second leg and / or side facing away from the second leg, which has at least one projection, wherein at a front end of the angle profile, an end wall is arranged in a normal to that of the extends second plane spanned plane, and wherein the end wall has at least one of the support facing, projecting connecting element, which is positively connected to the at least one projection. This makes it possible to produce the angle profile in the extrusion process and then easily connect the end wall with the angle profile, in which this is plugged with the connecting element to the corresponding end face of the angle profile, that the connecting element engages under the supernatant of the support.

It is advantageous if the support is designed in a normal to a plane defined by the first leg first plane and normal to the second leg spanned vertical plane cross-sectional plane is substantially L- or T-shaped, with an integrally formed on the first leg first leg portion and a transverse arranged thereon, the projection forming the second leg portion, by a along the first leg extending clearance or along the first leg extending groove of the latter is spaced. This results in a compact and stable support, which can be formed in the extrusion of the angle profile of this.

The angle profile may have at least two spaced apart transversely to the longitudinal extent of the first leg bearing, which are facing each other with their projections, wherein the end wall has at least one lug-shaped connecting element which engages under the two supernatants of Auflagerpaars. The end wall is then even better connected to the angle profile.

In an expedient embodiment of the invention, the angle section at least two web or strip-shaped supports, which are parallel to the second leg and arranged at different distances to this, wherein between these supports at least two sealing lips are arranged, which are also parallel to the second leg run and are arranged at different distances to this. Due to the multiple existing sealing lip, the on-board profile can be better sealed against the windowsill. Between the web-shaped supports, the sealing lips are protected against mechanical damage.

In a preferred embodiment of the invention, the second limb has a predetermined bending line arranged parallel to the first limb and spaced therefrom and the free edge of the second limb, along which a free edge region of the second limb relative to a partial region arranged between the desired bending line and the first limb of the second leg is bendable to the first leg, preferably by about 90 °. The angle profile can then be converted by pivoting the free edge region of the second leg to the desired bending line in a simple manner in a profile with C-shaped or U-shaped cross-section. The sill can then be used with one of the soffit of the masonry facing side edge region between the first leg and the angled free edge of the second leg. The free edge of the second leg is preferably narrower than the first leg.

With regard to the kit of the aforementioned type, the above-mentioned object is achieved in that the kit a left and a right side profile according to one of claims 1 to 10, the sill and an attachable under this Dämmkeil that the board profiles are designed such that the sill is installed between them when the second leg of the board profiles facing the masonry of the window reveal and the first leg of the Dämmkeil are that the kit has a left and a right soffit plate of a heat-insulating material, and that the soffit plates each have at least one finished, possibly paintable or coatable with a top coat surface. With the help of such a kit, a wall opening of a building in which a window is arranged to be heat-insulated in a simple manner and without cement.

It is advantageous if the kit has a window with a window sill, on the left and / or right edge outside a first widening profile is arranged, and / or if at the bottom of the window sill below a second widening profile is arranged. The at least one broadening profile is then arranged after the installation of the window between this and the building wall in the wall opening in a straight extension of the reveal panel or in a straight extension of the insulating wedge and / or the windowsill. Thus, even when using a low-cost, commercial window sufficient space for the installation of the reveal plates, the Dämmkeils and / or the windowsill available. It is even possible to provide a natural or artificial stone slab as a window sill.

It is advantageous if the kit has at least two connection profiles, which are at least partially configured as U-profiles, which are attachable to an in use position the frame facing edge region of the reveal plates and / or the Dämmkeils, wherein the connection profiles two by a U-cross bar with each other have connected U-legs, and wherein the U-transverse web is coated on its side facing away from the U-legs back with a seal extending along the connection profile. The connection profiles allow a tight connection of the soffit plates to the window sill. In addition, the reveal plates can be mounted faster to the building. As a seal, a sealing tape or a bond can be provided.

a representation similar Fig. 14 , but in addition to the insulating wedge two board profiles are mounted between which an outside window sill can be inserted.

A kit for the thermally insulated installation of a sill 1 in a wall opening on which a window 2 is arranged, has a left side profile 3 and a right side profile, which receive the sill 1 between them. Each on-board profile 3 has in each case an angle section with a first leg 4 and a second leg 5, which is arranged approximately perpendicular to the plane spanned by the first leg 4 in a plane spanned normal to the longitudinal axis of the first leg 4. The left side profile 3 is designed in mirror image to the right side profile.

In the installed state, the first leg 4 lies with its underside flat against a slope 6 of a Dämmkeils 7 ( Fig. 2 ), which is arranged at the lower end of the wall opening and extends in the horizontal direction parallel to the plane defined by the wall opening or the window 2 plane. The Dämmkeil 7 lies with its underside on the wall breakthrough delimiting masonry and an externally applied to the masonry thermal insulation layer on the plane in which extends the top of the Dämmkeils 7, has a predetermined by the wedge angle α of the insulating wedge 7 gradient from the Window 2 to the front edge of the Dämmkeils 7 drops out. The wedge angle α or the gradient is preferably at least 5 °.

At its edge having the lower wall thickness, the insulating wedge has a groove into which a first piercing profile 8 engages. If necessary, the male profile 8 may be secured in the groove with adhesive or adhesive tapes.

At the first Einsteckprofil 8, a first tissue flap 9 is fixed, which at an angle of about 90 ° from the plane which faces away from the slope 6 Underside of the insulating wedge 7 is clamped, projects downwards. When installing the Dämmkeils 7 in the wall opening of the first tissue flap 9 is plastered in a non-illustrated in the drawing mortar layer, which is applied after installation of the thermal barrier coating on the masonry outside of the thermal barrier coating.

The second leg 5 of each board profile 3 is in the installed state, each with its back facing an associated reveal of the masonry, namely the second leg 5 of the left profile 3 of the left soffit and the second leg 5 of the right profile of the right soffit. The on-board profiles 3 are preferably fixed with the aid of adhesive on the insulating wedge 7, on the reveal of the masonry and / or the window sill during assembly.

As in 3 and 4 is particularly well recognizable, the first leg 4 on its upper side more, each formed as a projection supports 10, 11 for the sill 1 on the supports 10, 11 are web or strip-shaped and parallel to the second leg 5. In this case extend the supports 10, 11 each in a plane which is inclined relative to the plane defined by the second leg 5 plane. At their free ends, the supports 10, 11 each have an approximately parallel to the plane defined by the first leg plane arranged support surface for the sill 1

The supports 10, 11 are arranged at different distances from the second leg 5 and spaced laterally from each other by gaps. In each case two supports 10, 11 are assigned in pairs to each other and inclined to each other with their free edges. In this case, a first support 10 is inclined relative to the plane defined by the second leg 5 plane to the right and a second support 11 relative to this plane to the left.

At the top of the first leg 4, moreover, a plurality of sealing lips 12 are arranged, which protrude beyond the supports 10, 11 normal to the plane defined by the first leg 4 (FIG. Fig. 3 ). The legs 4, 5 and the supports 10, 11 are made of a thermosetting plastic and the sealing lip of a thermoplastic material, which is softer than the thermosetting plastic Both plastics are integrally connected. This can be achieved be that the on-board profile 3 is produced as an extrusion profile and the two plastics are integrally connected by merging of different plastic melts and subsequent extrusion through a profile nozzle.

In Fig. 1 and 3 It can be seen that the sealing lips 12 are each laterally spaced from the second leg 5 and from each other. The sealing lips 12 are arranged in a free space located between the bearing pairs and spaced from each other by interspaces and from the supports 10, 11 of these bearing pairs.

The sealing lips 12 are each web-shaped or strip-shaped and extend in a plane which is inclined relative to the plane defined by the second leg 4 plane. As in Fig. 4 can be seen, deform the sealing lips 12 under load with the windowsill 1 and then elastically on the underside of the sill 1 on. It can clearly be seen that the sealing lips 12 are arranged with their free ends in the amount of the bearing surfaces of the supports 10, 11, when the sill 1 flat on the supports 10, 11 rests.

At a mounting position facing the window sill front end of the angle section, an end wall 1 3 is arranged, which extends in a plane which is normal to the plane defined by the second leg 5 plane. The plane in which the end wall 13 extends encloses, with the plane spanned by the first leg, an angle which is greater than 90 ° about the wedge angle α of the insulating wedge. As a result, the end wall 1 3 comes with its rear side facing away from the first leg 4 flat on the window sill to the plant, when the on-board profile is installed in the wall opening.

The end wall 13 has at its lower edge adjacent to the first leg 4 two lug-shaped connecting elements 14, which extend parallel to each other and to the plane defined by the first leg 4 plane. The connecting elements 14 engage in a form-fitting manner between the paired supports 10, 11. The supports 10, 11 each overlap with an overhang caused by the lateral inclination of the supports 10, 11, an edge region of the connecting element 14. During assembly of the Board profiles, the end wall 13 is positioned on the front side of the angle profile, that the connecting elements 14 facing the between the pairwise facing supports 10, 11 spaces. Thereafter, the end wall 13 and the end face of the angle profile are moved toward each other until the end wall 1 3 comes to rest on the end face of the angle profile. The connecting elements 14 are then held in a form-fitting manner between supports 10, 11 and the first leg 4 of the board profile.

As in Fig. 1 and 3 to 5 can be seen, the second leg 5 a plurality of parallel to the first leg 4 arranged, spaced therefrom and the free edge 15 of the second leg 5 predetermined bending lines 16, which are each formed by a notch. Along the predetermined bending lines 16 of the free edge 15 of the second leg 5 is in each case relative to a arranged between the predetermined bending line 16 and the first leg 4 portion of the second leg 5 on the first leg 4 is bent to. As in Fig. 7 can be seen, the on-board profile 3 at angled second leg 5 has an approximately C-shaped cross section, wherein the first leg 4 is wider than the angled edge 15 and with its second leg 5 facing away from the edge laterally beyond the edge 15. The vertical distance between the plane in which the support surfaces for the supports 10, 11 are arranged, and the edge 15 corresponds to the thickness of the sill 1 or is slightly larger than this, so that the sill 1 in the assembly between the first leg. 4 and the edge 15 can be inserted.

The kit also has a left and a right Fertiglaibung 17 with a reveal plate 18 made of a heat-insulating foam on their facing away in the mounting position of the soffit of the masonry front reveal the soffit panels 18 each have a finished surface 19. This need not be edited after installation. The surface 19 has a rough structure and can be coated and / or painted with a top coat adhering thereto if necessary. At its front edge facing away from the window sill, the reveal plate 18 has a groove 20 into which a second insertion profile 21 engages. If necessary, the second male profile 21 may be secured with adhesive in the groove 20.

In Fig. 10 It can be seen that the insulating wedge 7 laterally adjoins the reveal plate 18 and that during installation on a groove located between Dämmkeil 7 and reveal plate 18 a sealing track 22 is applied, which seals the reveal plate 18 against the Dämmkeil 7.

At the second insertion profile 21, a second tissue flap 23 is fixed, which protrudes at an angle of about 90 ° from the spanned by the reveal plate 18 level. When installing the reveal panel 18, the second tissue flap 23 is plastered into the mortar layer, which is applied to the exterior of the thermal insulation layer after assembly of the thermal barrier coating on the masonry and overlapped with the surface fabric of the facade insulation.

In Fig. 11 It can be seen that the kit also has a window 2 with a window stock 24, on the left and / or right edge outside a first widening profile 25 (FIG. Fig. 12 ) is arranged. This ensures that outside of the widening profile 25 of the required for the installation of the reveal plate 18 Baurum is present. On the underside of the window sill 24, a second widening profile 26 is provided, the outer surface of which is covered by the insulating wedge.

The kit also has three connection profiles 27, which are configured in sections as U-profiles, which are attachable to a in use position the window frame 24 facing edge region of the reveal plates 18 or the window frame 24 facing edge region of the insulating wedge 7. The connection profiles 27 each have two interconnected by a U-cross bar 28 U-legs 29, between which the windowstock 24 facing edge region of the reveal plate 18 and the Dämmkeils 7 can be introduced. The U-transverse web is coated on its rear side facing away from the U-legs and on its front side in each case with a seal 30, 31 which extends in the longitudinal direction of the connecting profile 27 without interruption. In Fig. 13 is still recognizable that the side of the configured as a U-section portion of the connection profile 27, a cover leg 32 is arranged, which is arranged in the plane defined by the U-crossbar plane or substantially parallel thereto. As in Fig. 14 it is recognizable Covering the cover leg 32 in the assembled position, the outer edge of the window stock 24th

In Fig. 15 It can be seen that after installation of the on-board profiles 3, the window sill 1 can be inserted between the on-board profiles 3. The installation of the system ensures the tight connection of the facade insulation or plaster system already during the construction phase. Ingress of water into the insulation or plaster system, the masonry, the timber stand construction or the multi-shell masonry is prevented before any window sill 1 is installed.

Furthermore, the sill 1 can be easily replaced, repaired or changed at any time.
