Description

 Windowsill, as well as tail, for it

The invention relates to a window sill for covering a parapet below a pus- ter or a door, as described in claim 1.

DE 20 2009 007 660 Ul describes a profile of a window sill fastening for a Parapetabdeckelement, which in the direction of its longitudinal extent distanced S timenden and a bottom and a side facing away from it has top. At least one end part is connected to the Parapetabdeckelement in the region of a front end. The profile is designed substantially U-shaped profile towards Parapetabdeckelement out and has approximately parallel to the Parapetabdeckelement extending aligned and in the vertical direction with respect to the longitudinal extent of the Parapetabdeckeiements spaced from each other arranged first and second leg, which are interconnected via a base web. On the side of the underside of Parapetabdeckeiements adjacent arranged second leg at its end remote from the base web a projecting towards the bottom of Parapetabdeckeiements first supporting web is arranged. On this support bar a sealing profile is attached. From DE 90 07 058 Ul is a windowsill with a window, such as

Aluminum, made known, which is set in the masonry formed by the masonry window and fixed with its back on the window frame. At the side edges of the window sheet a respectively formed in Querschnit U-shaped Bordstück is arranged. This piece of board has a vertical side wall and parallel to the window plate extending angled overlap webs. Furthermore, in the end of the window sheet a

Protective sleeve made of metal, preferably made of aluminum, which viewed in Embauzustand includes a Bodenwandungssteg, a vertically upwardly angled Seitenwandungssteg, a parallel to the Bodenwandungssteg running aligned guide web and angled away from the Bodenwandungssteg end of the Bodenwandungsstegs vertically upwardly angled support web. To form the termination unit, the protective sleeve is pushed or pushed over from the side over the piece of board, so that the side wall is arranged to form an expansion joint at a lateral distance from the side wall web of the protective sleeve. The guide bar is located either form-fitting on the Überde- or at a small distance above the latter. On the inside can be applied to the Seitenwandungssteg a soft elastic, preferably foamed plastic tape, which is suitably as thick as the intended expansion joint. The protective sleeve is fastened with its Seitenwandungssteg and Bodenwandungssteg the masonry, this being done by means of a silicone sealant or the plaster commonly used. The width of the expansion joint was based on the expected! Motion play of the window pane. The length of the protective sleeve is dimensioned such that it grips the window reveal and projects beyond the masonry towards the front. In this training could not be achieved in all cases a sufficient tightness in the end of the windowsill.

DE 93 05 776 Ul describes a window sill with a cover part and side profile parts for holding the cover part. At least two legs are present at the lateral profile part, wherein on at least one of these two legs a bulge is provided, which is arranged at a distance from the web of this profile part and directed towards the other leg of these two legs out. Thus, the holder of the cover part and a possible length compensation of the same in the profile part is made possible. Again, not all applications, a sufficient tightness of the windowsill is again achieved.

The present invention has for its object to provide a sill, which allows a change in length of the Parapetabdeckelements relative to a held on the building wall tail, while a perfect seal the sill towards the building wall is achieved. In addition, but also an end piece to be created, which can be easily and securely attached to a building wall and held there. Furthermore, but also a method for assembling a sill to cover a parapet below a window or a door can be specified, with which before the installation of the sill on the window or door a related, a secure seal enabling assembly can be created.

An object of the invention is achieved in that the second leg of the end piece arranged adjacently to the underside of the parapet cover element projects beyond the end part in the direction of the longitudinal extension of the parapet cover element with a section, and the sealing element in the section of the second leg of the part projecting beyond the end part End piece is arranged and is arranged extending between the underside of Parapetabdeckelements and the second leg, wherein the sealing element connected to both the underside of the Parapetabdeckelements and the second leg of the tail, in particular glued, is.

The advantage resulting from the features of claim 1 lies in the fact that in the area of the underside of the Parapetabdeckelements and fixed in the building wall end piece a separate trough-shaped or trough-shaped drain can be created, which through the seal a safe discharge of water over its longitudinal extent allows. This can drain in the corner between the cover and the final part entering water in the specially sealed channel below the Parapetabdeckelements and does not get into the building wall. As a result of the additionally protruding section of the further leg of the end piece protruding beyond the Abschiussteii, even when water enters between the Parapetabde- ckelemeni and the final part of this can be removed in the specially created and sealed channel over the entire Parapettiefe. Thus, not only a sufficient longitudinal movement of the Parapetabdeckelements within the end pieces is achieved in this section of the sill, but also prevents an unwanted entry of water towards the building wall secured. The two-sided bonding of the sealing element also has the advantage that an even more secure seal between the sealing element and the respective surfaces facing the sealing element can be achieved. In addition, however, sufficient retention of the end piece on the Parapetabdeckelement can also be achieved for the duration of the assembly. By providing the support web, additional channeling can be created in the region of the underside of the parapet cover element and the limb of the end piece. In addition, however, it can also be achieved a sufficient protection of the sealing element during installation and the intended use of the sill.

A further advantage is an embodiment according to claim 2, since a bilateral, even better protection for the arranged in this receiving channel sealing element is achieved.

By, the training according to claim 3, it is possible not only to achieve a secure protection of the sealing element between the supporting webs, but also a simple Ferti- allow the tail in an extrusion or extrusion process. By an additional concern of the support bar on the underside of the Parapetabdeckelements still too high compression of the sealing element and thus damage thereof can be prevented.

According to another Ausfiihrangsvariante according to claim 4 be a possible adhesion of the Dichtelemenis at the height or thickness of the channel limiting surfaces also an additional Versteilmöglichkeit the Parapetabdeckelements relative to the tail allows, without causing damage to the Dichtelemenis to or the supporting webs can come.

Also advantageous is a development according to claim 5, as a secure seal between the legs of the tail and the underside of the Parapetabdeckelements can be achieved even in different applications and installation situations. However, slightly varying height distances can also be bridged without impairing the tightness of the channel.

Through the development according to claim 6 ensures that thereby exposed in this area, sharp edges are avoided. In addition, a directed removal of water can also be achieved by this bridge. The bridge can so also as so-called

Drip nose be designated, which is arranged or formed over the longitudinal extension of the first leg.

As a result of the construction according to claim 7, at least one predetermined breaking point can be formed within the leg in a simple manner in the region of the individual indentations so as to facilitate separating out of sections of the leg for the arrangement of guide rails.

Also advantageous is a design according to claim 8, since this already a certain directed discharge of water in the corner region of the Parapetabdeckelements can be achieved. In addition, as well as a stiffening of the Parapetabdeckelements can be achieved in its end portion and still made a sufficient adjustment of the unit from Parapetabdeckeiement and final part relative to the tail. According to an embodiment as described in claim 9, a direct contact of the Parapetabdeckelements or arranged thereon end part of the base web of the tail can be prevented so in this area. With appropriate training and choice of material of the damping element but this can also exercise a certain sealing function.

In this case, an embodiment according to claim 10 proves advantageous, since a secure seal and cover starting from the Parapetabdeckelement towards the window can be achieved. In addition, an unhindered arrangement of the end piece is made possible up to the immediate area of the window or its frame. Furthermore, it can also be done with a secure discharge of water from the window facing longitudinal portion of the Parapetabdeckelements. Another advantage is an embodiment according to claim 11, as in the respective corner area a passage of water, starting from the windowsill, towards the building wall, can be secured secured.

However, the further object of the invention can also be solved independently by the features of claim 12. The advantages resulting from the combination of features of this claim are that thereby an end piece for receiving a Parapetabdeckelements can be created, which are already held sufficiently strong and stable on the building wall and secured at the beginning of installation of the sill over the additional fastening device on the outside can. In addition, however, so that starting from the Parapetabdeckelement applied to the tail pull-out forces can be removed directly to the masonry or the building wall, whereby the same can be achieved in the installed state of the tail a permanent support. By means of this fixed arrangement of the end piece via its own associated fastening device, however, cracking of the external plaster in the immediate vicinity of the end piece can also be avoided over a very long period of use.

In. The training according to claim 13 can thus be a simple removal of tensile forces, starting from the Parapetabdeckelement over the tail towards the building wall transmitted be gene. By this directly opposite arrangement of the fastening device with respect to the Parapetabdeckelements but so the construction and the introduction of moments can be avoided on the tail. As a result, a directional transmission of forces occurring, starting from the Parapetabdeckelement over the tail to the fastening device and further achieved on the building wall.

It is also possible an embodiment according to claim 14, since this no additional components must be provided and depending on the needs and installation situation directly when moving the windowsill, the fastening device in the form of at least one pivotable from the tail or foldable tab can be formed.

Finally, however, a training, as described in claim 1.5, possible, as a result, an easy-to-produce tail can be created with a part of the fastening device. Depending on the fastening situation, the corresponding fastening element can be inserted into the guide arrangement for forming the fastening device and subsequently connected to the building wall.

The object of the invention can, however, independently of this also be solved by a method for assembling a window sill for covering a parapet according to the features indicated in claim 16. The advantages resulting from the combination of features of this claim are that so before assembly of the entire sill a related and also held together structural unit can be created in which not only a length compensation of Parapetabdeckelements due to temperature fluctuations unhindered but also an intrusion moisture in the building wall in the area of the entire windowsill, secured can be avoided. By providing the support bar and the adjacently arranged sealing element so a further drainage channel is created below the Parapetabdeckelements over which especially in the rear corner penetrating moisture secured without penetration of the same can be dissipated into the building wall to the outside. As a result of the bonding, in particular the gluing of the sealing element both with the end part projecting beyond the part section of the web and the underside of the Parapet cover element, a relative pre-positioning of the end piece on the Parapet cover element can be achieved. This is because, where appropriate, when assembling an expansion joint for the temperature-related changes in length of Parapetabdeckelements is to be formed. Subsequent to this pre-assembly or assembly of the window sill so this unit formed can then be arranged and fixed to the frame part of the window or the door. The marginal mounting of the sill in the area of their front ends can then be done via the tail with the load-bearing building wall.

However, it is also an approach according to the feature specified in claim 17 advantageous, since a more precise alignment of the tail with respect to the end part or the front end in parallel alignment is made possible. By the subsequent removal of the Di stanze] .ementes before M ontage of the windowsill so the expansion of the Parapetabdeckelements can be substantially facilitated due to the temperature fluctuations.

Finally, however, a procedure according to the features indicated in recital 18 is expedient, since dami an even safer Abddichtung the corner of the windowsill is achieved in the rear corner region. This prevents the penetration of moisture into the building wall even in driving rain connected with higher wind speeds.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

By way of introduction, it should be noted that in the variously described embodiments, identical parts are provided with the same reference symbols or the same component designations. in which the disclosures contained in the entire description can be applied mutatis mutandis to the same parts with the same reference numerals or the same component designations. Also, the position information selected in the description, such as top, bottom, side, etc. are based on the directly described and illustrated figure and are to be transferred to a new position analogously to the new situation.

1 to 3 is an example of a window area with a window 1 with a window frame 2 (window), optionally guide rails 3 for a sunshade 4 or fly screen, and with a window outside 5 arranged window sill, which in the area by a first Parapet 6 limited building opening between in the direction of a window width from each other spacers covering, shown. In this case, the window 1, in particular its frame 2 indicated by dash-dotted lines only greatly simplified. The window sill 5 is arranged here below the window 1 in the region of an outer side of a building wall 7. Another sill 8 (inner window sill) covers another building formed by another parapet 9 protruding below the window 1 on the inside of the building wall 7.

The building wall 7 has, according to the embodiment shown a masonry 10 and arranged on the outside of the masonry 10 thermal insulation 1 1. The thermal insulation 11 is formed by a full thermal insulation (thermal insulation composite system), glued in the insulation boards on the outer wall and then plastered their remote from the outer wall surface thin. On the other hand, it is also possible that the thermal insulation 11 is formed by a mounted on the outer wall thermal protection. The window 1 can be attached via mounting bracket 12 on Mauenverk 10. But it would also be possible to make the building wall 7 by a wooden wall, a timber bolt construction or other materials and construction methods.

1, the window sill 5 (outer window sill) arranged on the outside of the building wall 7 is shown, which, depending on the design, can also be formed from a plurality of individual components. In the present exemplary embodiment, the window sill 5 comprises a profile-shaped parapet cover element 13, which has front ends 14 which are distanced from each other in the direction of its longitudinal extension and an underside 15 and an upper side 16 facing away from it. Furthermore, the window sill 5 comprises at least one end part 17, which is connected to the Parapetabdeckelement 13 in the region of one of the front ends 14, and at least one end piece 18, which is designed to be substantially U-shaped profile towards the Parapetabdeckelement 13 out. The Parapetabdeckelement 13 may be formed of a metallic material, which, depending on the training this has a particular Z-shaped cross-section. In most cases, aluminum materials, aluminum alloys or other metal alloys, or even plastics are used here, which are usually also weather-resistant within certain limits. A corresponding external coating in the form of paints, powder coatings or the like known from the prior art is usually also provided. Thus, the Parapetabdeckelement 13 here has a Parapet 6 of the building projection covering cover 19, an upwardly projecting from this and the window frame 2 or a window frame Anschiusssteg 20 and directed by this nac below and on the building wall 7 projecting eaves 21.

If the closing part 17 is likewise arranged or positioned at at least one of the front ends 14 of the parapet covering element 13, this or together with the parapet covering element 1.3 forms an approximately shell-shaped or trough-shaped component towards the building wall 7.

In most cases, there is still an embedding of the sill 5, 8, in particular of its cover 19 in an unspecified potting. This may be a foamable adhesive, a mortar bed, in particular a mortar containing insulating material, or other bonding agents.

The at least one end piece 18 is designed to be substantially U-shaped in profile towards the parapet cover element 1.3 and extends at least over a partial length of the depth of the Parapet cover element 13. Furthermore, the end piece 18 is aligned approximately parallel to the package cover element 13 and oriented in the vertical direction with respect to the longitudinal extension of Parapetabdeckelements 13 spaced from each other arranged first and second legs 22, 23, which are interconnected via a base web 24. In Fig. 3, the sill 5 is shown in one of its end portions without the building wall 7, in which sill 5 on Parapetabdeckelement 13, in particular the cover 19, the end portion 17 is arranged thereon and optionally also held thereon. In this case, the closing part 17 together with the Parapetabdeckelement 13 in the region of its front end 14 in one of the two legs 22, 23 and the base web 24 unlimited Innenrauni 25 of the tail 18 is added.

In order to be able to absorb a longitudinal expansion of the Parapetabdeckelements 13 together with the attached thereto end part 17 with a change in length in the direction of its longitudinal extent, an expansion joint 27 is formed between the end part 17 and the end part 17 facing inner surface 26 of the base web 24 of the end piece 18. This expansion joint 27 is preferably provided on both sides of the Parapetabdeckelements 13 and is to be dimensioned so that depending on the material properties of Parapetabdeckelements associated change in length can be done with a change in temperature without collision.

The terminating part 17 can be designed differently and has an approximately L-shaped cross-section in the exemplary embodiment shown here. Thus, a first leg portion 28 is aligned approximately parallel to the base web 24 of the tail 18. A second leg portion 29 has a substantially parallel with respect to the Parapetabdeckelements 13 aligned course. The two leg portions 28, 29 close as seen in cross section at an angle of 90 ° to each other.

In a known manner, the end part 17 has a holding device 30, which serves to receive the front end 14 of the Parapetabdeckelements 13. So here is the holding device 30 as a groove or slot-shaped receptacle in the corner inside between the two leg portions 28, 29 is formed. Between the second, further leg part 29 of the end part 17 and the underside 15 of the Parapetabdeckelements 13 a channel 31 is formed by a double-cranked design of the leg portion 29. This channel 31 is used inter alia for the removal of liquids, in particular rainwater, as this is to be discharged from the connecting web 20 of the cover 19 toward the eaves web 21. This channel 31 is to extend at least to the outside of the building wall 7, but preferably beyond this, so as to allow a free drainage or drainage of rainwater without this directly on the outside of the building wall. 7 runs along. This training is well known and will therefore not be discussed further.

Furthermore, it can still be seen here that a damping element 32 can be arranged or provided in the expansion joint 27 formed between the base web 24 of the end piece 18 and the end part 17, in particular its first leg part 28. The damping element 32 shown here in a simplified manner bridges the gap between the base web 24 and the first leg part 28 that forms the expansion joint 27. In this case, however, the damping element 32 can also additionally assume a sealing function. In this case, this element may be referred to as a damping and / or sealing element. In any case, the damping element 32 in a sufficiently large temperature range, such as this in the usual application, for example, between -40 ° C and -70 ° C up to + 80 ° C and more, be used. In this large temperature range, the material for forming the damping element 32 elastic properties, optionally with a sufficient restoring force, so as always to completely bridge the expansion joint 27 between the base 24 and the first Schenkekeil 28 of the end part 17.

It has been found to be advantageous if the damping element 32 is not arranged over the entire longitudinal extent of the expansion joint 27. This is because such a longitudinal extension of the Parapetabdeckelements 13 is made possible without it must come to an elastic deformation of the damping element 32 over its entire longitudinal extent. As a result, the introduction of force during expansion is reduced and thus prevents a relative displacement of the end piece 18 with respect to the building wall, which could possibly lead to an unwanted cracking. Thus, for example, the damping element 32 can be provided only in the front immediate field of view, which then bridges the expansion joint 27 to the extent that an insight and thus an otherwise remaining dark gap is avoided. Thus, the damping element 32 is only ready or partially arranged within the expansion joint 27. It can also be seen here that the second leg 23 of the end piece 18 arranged adjacent to the underside 15 of the parapet cover element 13 projects beyond the end part 17, in particular its second leg part 29, in the direction of the longitudinal extension of the parapet cover element 13. In this case, that portion of the second leg 23, which on the End part 17 on the side facing away from the base web 24 side protrudes hereinafter referred to as a section or subsection. Furthermore, between the underside 15 of the Parapetabdeckelements 13 and the final part 17, in particular its leg portion 29 superior portion of the second leg 23 of the end piece 18 a between them erstre- ckendes Dichtelemen 33 is arranged. With this sealing element 33 it is achieved that in the area of the underside 15 of the Parapetabdeckelements 13 and arranged thereon end portion 17, a further channel 34 is formed, which extends at least over the depth nerstreckung of the end piece 18 on the Parapettiefe of Parepets 6. In order to achieve a defined channel height of the channel 34 between the underside 15 of the Parapetabdeckelements 13 and the leg 23, the end piece 18 at its end remote from the base web 24 end of the second leg 23 in the direction of the bottom 15 of the Parapetabdeckelements 13 projecting, first support web 35 have. The piece web 35 is preferably aligned parallel to the longitudinal extension of the end piece 18 and extends beyond the depth of the parapet 6 below the Parapetabdeckelements 13. The sealing element 33 is then arranged in that the second leg portion 29 of the end portion 17 superior portion of the second leg 23 of the end piece 18 and bridges the formed gap or channel 34 in the direction of its height and thus in a vertical direction with respect to the underside 15. Thus, in this area outside the closure part 17, in particular its further leg 23, the channel 34 is sealed in its longitudinal extension and thus in the direction of the parapet depth.

Furthermore, it is possible for the end piece 18 to have on its second limb 23 a further support web 36 projecting in the direction of the underside 15 of the parapet cover element 13. This further supporting web 36 is likewise arranged in the section of the second limb 23 projecting beyond the terminating part 17, in particular its further limb part 29, but arranged at a distance from the end thereof. The further support web 36 is indicated in dashed lines.

The sealing element 33 is then accommodated in the case between the two support webs 35, 36 Aufnahmeu in this case. To the U-shaped end piece 18 as To be able to form the profile part, the first support web 35 and / or the second web piece 36 is parallel to the base 24 of the tail 18 aligned.

When forming the window sill 5, the end piece 18 serves to be held and fastened fixedly to the building wall 7. In this case, the end piece 18 may also extend into the building wall 7 and so at least partially or partially absorbed by this. In this case, a fixed support of the end piece 18 is given relative to the building belt 7. In order to allow for temperature differences and the associated changes in length of the Parapetabdeckelements 13 together with the optionally arranged thereon or held end part 17, a floating receptacle or storage thereof within the interior 25 of the end piece 18 is provided. A vertical height in the vertical direction with respect to the underside 15 of the support webs 35, 36 serves to arrange the parapet cover element 13, in particular its cover part 19, so far away from the leg 23 that a free movement of the end part 17, in particular of its leg parts 28 , 29 relative to the two legs 22, 23 is possible. In this case, the support webs 35, 36 take over or support the Parapetabdeckelements 13 on the other leg 23 of the end piece 18. This is the or the support webs 35, 36 on the underside 15 of Parapetabdeckelements 13 at.

The sealing element 33 is arranged with respect to the or the support webs 35, 36 such that it is arranged at a lateral distance with respect to at least one of the support webs 35, 36. The sealing element 33 serves to seal the distance between the underside 15 of the Parapetabdeckelements 13 and the leg 23 in the direction of the Parapettiefe sealing. In this case, a variety of known from the prior art training and materials for the formation of the sealing element 33 find application. Thus, the sealing element 33 may be formed from a precompressed sealing strip. This precompressed sealing tape can also be referred to as so-called Kompriband, stop tape or joint tape, which is a foam sealing tape based on polyurethane. An additional impregnation can also be applied or incorporated onto and / or into the foam sealing tape. Such a band has the properties that it slowly expands after insertion into a joint or a gap and seals against the bridging edges or surfaces to be bridged. Furthermore, it is possible that the sealing element 33, if this is formed from the previously described, pre-compressed sealing strip, both with the bottom 15 of the Parapetabde- ckelements 13 and the second leg 23 of the end piece 18 is connected, in particular glued. Through this connection, a secure contact and support as well as a very good seal is achieved in the connection area of the Parapetabdeckelements 13 and the leg 23. Due to the additional elastic properties of the material for forming the density element 33, this can absorb the relative displacement of the Parapetabdeckelements 13 with respect to the fixed, further leg 23 of the end piece 18, without this being damaged. In order to be able to carry out these relative displacements, which take place predominantly in the longitudinal extent of the Parapetabdeckelements 13, the above-described lateral distancing of the density element 33 from the support or legs 35, 36 is favorable. The sealing function remains unaffected and maintained. However, it would also be possible to form or provide the sealing element 33 with at least one or more sealing lips, which either abuts against the underside 15 of the parapet covering element 13 or on the leg 23 of the end piece 18. Thus, in turn, the corresponding relative displacement of Parapetabdeckelements 13 can be made with respect to the fixed end piece 18, without losing the sealing function is lost.

Furthermore, it is possible for the end piece 18 to have a web 37 protruding in the direction of the second leg 23 at its end remote from the base web 24 of the first leg 22. This is indicated in dashed lines and can represent, for example, a drip nose and optionally an additional reinforcement of the leg 22.

In order to enable a simple and comfortable arranging of guide rails 3, the end piece 18 can be attached to a Parapetabdeckelement 13 facing inside 38 of the first leg 22 with at least one in the direction of the longitudinal extent of the first leg 22 extending first notch 39 and at least one transverse thereto extending second notch 40 be provided. These two notches 39, 40 are indicated in the region of the first leg 22 by dashed lines and serve as a target -Bruchstellen so as to remove a part or a portion of the leg 22 of the tail 18 can be felt without doing sawing or Trennschleifvorgänge. It is thus possible, as seen in the longitudinal extent of the end piece 18 and thus in the direction of the parapet depth, to break off or separate corresponding sections depending on the width of the guide rail 3 to be received, as has been described, for example, in the Austrian patent application AT 508 271 A1.

As already described above, the Parapetabdeckelement 13 on the window 1 facing or zuwendbaren on the upstanding connecting web 20, which serves for fixing the Parapetabdeckelements 13 on the window 1 or its Blendralimen 2. It is advantageous if the connecting webs 20 projects beyond the first leg 22 of the end piece 18 to the side facing away from the second leg 23 side.

In order to achieve a perfect seal of the corner region, which is zuwendbar the window 1 or the door, can be arranged or provided in the one or more corners of the Parapetabdeckelements 13 and the end piece 18 each have an additional sealing element 41 which seals the corner outside , This additional, further Dichtelemen 41 is usually formed of a highly elastic, weather-resistant material or a combination of materials, soft in the corner outside of the connecting web 20 and the base web 24 sealingly applied, in particular glued. In the area of the underside 15 of the Parapetabdeckelements 13 there is a folding of subsections of the additional sealing element 41, wherein this has been shown simplified on the side facing away from the interior 25 side of the other leg 23 by a double layer of the additional sealing element 41.
