The intermediate wall portion is partially or completely overhanged. An independent claim is also included for a window plate mold part with a space inner side.

Description

The invention relates to a wall structure with a window opening and a window sill molding arranged on the window opening according to the preamble of claim 1.

Such window sill moldings are used at window openings to create a defined support area for the window frame and so faster fix the window frame exactly aligned in the masonry opening. The window sill molding is hereby usually a prefabricated component.

For example, a window sill part is known after the EP 1 788 182 A1 , which is fixed in the window opening, for example by means of plaster. The disadvantage here is that a careful preparation of the masonry opening for a proper installation and adjustment of the window sill part is required. Furthermore, it is disadvantageous that the use of such a window sill part already has to be taken into account in the planning of the shell, since the window sill molding used in the masonry opening reduces the space available in the masonry opening for the window frame. If the original window size were to be retained, the shell opening would have to be enlarged in order to be able to use the window sill part in the masonry opening.

Furthermore, it is known to support window sill moldings by means of these supporting struts, wherein two or more struts are mounted load-bearing in the masonry opening, namely on the window sill, ie the top of Support wall at the masonry opening. The struts thus extend on the one hand at least over a considerable part of the depth of the window sill, on the other hand support the window sill molding. The struts consist of two mutually telescoping rails, one of which is attached to the upper side of the window sill and the other on the underside of the windowsill profile. However, this arrangement is very complex, since the telescopic rails for load transfer must be made very stable. In particular, this structure also requires careful preparation of the masonry opening in order to be able to attach the struts and thus the window sill profile with sufficient accuracy to the wall. In addition, the space available for the window frame within the masonry opening space is also limited by the window sill molding, so that even here the use of the sill molding is already taken into account in the shell construction planning. Furthermore, the thermal insulation of the wall structure in the area of the struts is difficult.

The invention has for its object to provide a wall structure with sill molding in which without great planning effort or changes in the shell, the sill molding is used, the sill molding is easy to install and can be easily integrated into the wall structure. Furthermore, the invention has for its object to provide a corresponding window sill molding.

The invention is achieved by a wall structure with window molding according to claim 1 or by a window sill molding according to claim 19.

Thus, according to the invention, the window sill molding (also called "molding" for short) is arranged in front of the supporting wall, wherein the window sill molding is adapted for such an arrangement and load-bearing by means of a fastening means on the Fixed support wall and so overhangs the outside of the support wall superior partition wall area at least partially or completely. The insulating intermediate wall region, ie the insulating layer or insulating layer in this case has a lower load capacity than the support wall and is preferably the bulkhead immediately pre-set. The arrangement and attachment of the window sill molding on the outside of the support wall window sill profile can be attached as attachment component to the outer shell of the support wall, whereby a particularly careful preparation of the masonry opening is unnecessary, also because the outside of the support wall is usually sufficiently flat to a simple adjustment to allow the window sill molding and thus the window to be mounted to the masonry out. The assembly work of the window sill molding and the window is thereby substantially facilitated. Furthermore, the window sill molding can be positioned so that its use in the shell planning with respect to the window size to be used no longer needs to be considered separately, which is an additional advantage. The molded part can be attached to the supporting wall in such a way that its body practically no longer restricts the masonry opening. It may be arranged ≥ 25-50% or ≥ 75% -90% or preferably at least almost 100% of the body height below the window sill. On the other hand, the attachment of the molding to the support wall is thereby simplified, since no longer as conventional complex vertical anchors must be introduced into the window sill of the support wall, so that the longitudinal extension of these anchors parallel to the load transfer of acting on the sill molding gravity of the window, so vertically extending, are arranged and the anchors must then be dimensioned accordingly. The wall structure according to the invention or that in this window sill molding to be used thus allow easy and quick attachment and also a flexible Use on shell construction without additional planning measures. At most, therefore, here is the wall of the thermal insulation layer superior to reduce slightly in height, but this is feasible without problems, since the thermal barrier coating is not designed load-bearing. The window sill molding according to the invention is thus also particularly easy to integrate into a wall structure with thermal insulation.

The term "load-bearing" with respect to the support wall is understood here that this takes the load of the window (preferably completely absorbs) and safely removes into the load-bearing structure or is part of the load-bearing structure. Preferably, the supporting wall also absorbs the roof load. With regard to the fastening means, "load-bearing" means that the load of the window is transmitted predominantly (≥50% or ≥75%) or preferably completely into the supporting wall.

Preferably, the window sill molding is located directly on the outside of the support wall, at most except for a thin intermediate layer between the molding and support wall, which preferably has a thickness of ≤ 3-5 mm or ≤ 0.5-1 mm, preferably ≤ 0.02-0 , 05 mm, such as a slide. Preferably, such an intermediate layer is not provided.

The in the layer structure of the wall of the supporting wall on the outside superior intermediate wall area in the form of insulating layer or insulating layer is preferably placed immediately before the supporting wall. The insulating layer is preferably flat or full surface on the supporting wall. The insulating layer can be fastened to the supporting wall, preferably in such a way that ≥ 50-75% or preferably ≥ 85-95% of the intrinsic weight of the insulating layer is absorbed by the supporting wall or at least received by the fastening means acting therebetween (usually dowels or gluing) can (even if possibly a certain load transfer can still take place in other wall areas). The insulating layer thus provides as well as the supporting wall a Layer or layer of the wall structure and thus preferably extends with respect to the respective wall at least substantially over the same area as the support wall, possibly up to minor component adjustments, building connections eg in the range of masonry openings, balconies or the like. The term "insulating layer" is hereby generally understood to mean the heat-insulating area between the supporting wall and the facing shell (which forms the outer area of the wall structure). The term "insulating layer" denotes a concrete layer of thermal insulation material such as mineral wool, polystyrene or the like.

The insulating layer, which is at least partially overhanged by the window molding, can consist at least predominantly (ie for ≥ 50-75% by weight or ≥ 85-95% by weight or at least practically completely) of a conventional insulating material, such as mineral wool, Fiberboard, such as fiberboard and in particular foam boards, in particular polystyrene panels. The superior wall area may be self-supporting, so that it is only to be fastened to the supporting wall, for example by gluing and / or pegging.

The insulating material may have a thermal conductivity λ _R of ≦ 0.15 W / mK, preferably of ≦ 0.08-0.1 W / mK, particularly preferably of ≦ 0.05-0.06 W / mK, for example also in the range from 0.035 to 0.04 W / mK.

The thickness of the insulating layer can be ≥ 2-3cm, preferably in the range of 5-30cm or larger, usually in the range of 10-25cm or 10-20cm.

Preferably, according to the invention, the window sill molding largely overhangs the thermal barrier coating in its depth, for example by ≥ 50-75% of the depth of the thermal barrier coating (extension from the inside to the outside) or ≥ 85-95% of its depth, preferably practically completely, the window sill molding If appropriate, it can also protrude outward beyond the intermediate wall area or the thermal barrier coating, if appropriate, and can also be formed on the outside up to the weatherproof cladding or outer shell or a subarea thereof, although this is usually not necessary. By the molding, which preferably overhangs the insulating layer on the window, as far as possible, the top of the insulating layer is mechanically protected, for example, in further construction measures. The window sill molding in particular can be flush with the insulation layer on the outside.

The window sill molding has a body which has an attachable to the support wall and / or or fixable on this side surface (in installation position "back"), as well as a space outside side surface ("front") and a top and bottom, further on the body is preferably provided on the upper side of this projecting support area for a window frame. The support area can be designed as a rib projecting upwards from the carcass with optionally structured upper side. The molded part is then fastened or fastened to the supporting wall in such a way that the support region for the window frame is arranged projecting on the outside in relation to the supporting wall. The window frame can thus be arranged particularly advantageously by using the molding according to the invention of the support wall at least partially or completely pre-set. Here, the window frame with its back rest against the support wall. As a result, the window frame can be arranged partially or preferably completely with its cross-section within the insulation layer provided upstream of the supporting wall, which is particularly advantageous from a thermal-insulation point of view.

In general, the window frame can be fastened load-bearing independently of the window sill molding with additional fastening elements on the support wall. Regardless of this, however, the molding is together with its bearing wall side Attachment preferably designed such that it is completely load-bearing with respect to the window to be mounted, that is set so on the support wall, that the entire window weight can be absorbed by the molding. The horizontally oriented mounting base makes window installation much easier.

In this case, the window sill molding is particularly preferably fastened exclusively load-bearingly on the supporting wall and not load-bearing on the insulating wall provided on the outside of the supporting wall. The insulating layer does not have to take over a load-bearing function.

In general, the fastening element for fixing the window sill molding of a supporting wall may extend outside the space up to at least the support region for the window frame or may preferably fully support it. Preferably, the fastening elements have a length such that they are overhanged on the outside of the space from the wall region which is superior to the supporting wall, so that no thermal bridges are created to the outside.

The fastening means for the window sill molding is preferably designed such that this on the one hand supports the window sill molding load-bearing, on the other hand is arranged with a holding area between the supporting wall and the insulating layer. The fastening means can thus be fixed to the outside of the support wall. The fastening means may be formed in particular as an angle profile. This is on the one hand a simple and secure fixing of the molded part and thus also allows the window arranged on this, on the other hand, not a space within the window opening is taken by the fastener. Furthermore, the fastening means is covered on the outside by the intermediate wall region, so that heat bridges do not form to the outside, which is of essential importance for the thermal insulation wall construction in the region of the masonry opening. According to another preferred embodiment, the window sill molding with its rear side surface on the outside of the support wall may optionally be additionally glued. The bonding can be load-bearing, possibly also in addition to the above-described fasteners. Thus, the fastening means for the molding also extend completely within the area between the outside of the intermediate wall region and the support wall, spaced from the outside of the insulating layer, ie set back inwards.

Optionally, the fastening means can also be designed in the form of the window sill molding substantially horizontally penetrating fasteners such as screws / dowels.

Particularly preferably, the window sill molding is made of a thermally insulating material such as polystyrene foam, so that this also serves as a thermal insulation element in relation to the support wall. The molding may in this case consist of a material which has a thermal conductivity of ≦ 0.15 W / mK, preferably ≦ 0.1 to 0.12 W / mK, more preferably ≦ 0.06 to 0.08 W / mK, without further also in the range of 0.035 to 0.04 W / mK, as typical for thermal insulation materials. As a result, there is also a good insulation of the supporting wall in the region of the molded part. By using the molding according to the invention thus a wall structure is possible, which on the one hand allows a simple load-carrying attachment of the window, on the other hand, a thermally advantageous embodiment of the wall structure, especially in ventilated facade. The thermal insulation effect of the window sill molding may at least approximately correspond to that of the insulation layer, for example with a deviation of ± ≦ 30-50 of the same, preferably ± ≦ 10-20 thereof. The window sill molding can be a preferably internal reinforcements, for example, in the form of the molding passing through reinforcing struts or hollow sections, V or U profiles or other suitable profiles, etc., whereby even with heavy windows, the molding in its volume may consist of a preferably heat-insulating plastic.

The window sill molding may be attached to the support wall such that the top of the interior side directed portion of the window sill molding at least substantially flush with the window sill. Other components between the molding and the supporting wall in relation to the layer structure of the wall from the inside of the room to the outside of the room, are then not required. In addition, this allows the molding to be aligned in a simple manner relative to the support wall and thus also the desired position of the associated window can be determined. It is understood that this alignment of the molding on the support wall can be done exactly flush, or possibly taking into account adhesive or leveling layers. The height offset to the window sill should, if possible, not exceed ± 1-2 cm, preferably ≤ ± 3-5 mm or more preferably ≤ ± 1-2 mm. Preferably, the molding does not project upwardly above the window sill.

Preferably, an area of the window sill molding and the window sill cross-cover member is provided, for example in the form of a plate-shaped cover element, whereby the transition between the support wall and molding is covered. The cover element may be formed in the simplest case as a flat cover plate. The molding may in this case the interior facing side facing having a paragraph whose height is adapted to the thickness of the cover element, so that the laid on the lower, preferably horizontal, region of the paragraph cover element flush with the upper edge of the paragraph of the molding, optionally taking into account a adhesive layer. The cover element can in this case be dimensioned or cut to length, so that this flush with the inside of the room flush with the back of the support wall. This can be done on simple Way the masonry opening for receiving a window and a room inside windowsill are prepared, with few components and little effort. In particular, the cover element can be arranged on the shoulder of the molded part in such a way that it abuts the end face with the window sill molding, optionally a groove can also remain between the components. The contact surfaces of the window sill molding and cover plate preferably extend vertically in the mounting arrangement, but the abutment surfaces can also be configured and adapted to one another, for example in the form of multi-step shoulders, in the form of a retaining groove with a retaining projection on the two components mentioned to avoid a radially inwardly directed change in position of the cover element or the like. Optionally, the cover element may also have a collar on the inside, which overlaps, for example, the upper edge of the support wall on the inside, in order to give a clean finish, or which rests on the parapet. The collar is used to easily receive the windowsill.

Instead of a paragraph on the inside of the room in the window sill molding and the rauminnen- and space outside top can have a different level, so that the cover element can extend to the support area of the molding. The upper side of the cover element can then have at least substantially the same level as the outer space-side surface of the molded part. However, the aforementioned variant is more advantageous, since the body can be made more stable at the contact area for the window.

Facing the space outside, the body of the window sill molding can protrude beyond the support area for the window frame, preferably with an at least substantially horizontally extending top, which preferably has an angle of ≦ 5 ° or ≦ 2-3 ° with respect to the Horizontal, whereby the sill molding is particularly suitable for placement on a ventilated facade. The region of the body of the molding projecting outwards relative to the supporting area for the window frame can be in the range from 5 to 100 mm, for example in the range from 10 to 50 mm or in the range from 20 to 40 mm, corresponding to the respective requirements of the wall structure. The support area for the window frame is placed outside the room wall outside the supporting wall. The support area for the window frame is placed outside the room wall outside the supporting wall. The support area is arranged at the level of the thermal insulation composite system.

The body of the window sill molding preferably has parting marks which are arranged at intervals in the longitudinal direction (in the installation position, depth extension) of the molding, in particular on the side facing the interior of the chamber, preferably from the window support region to the back of the body. The separation marks may be arranged in a uniform grid over the mold part length. The separating markings can be designed as pure graphic markings or as cuts in the body, which extend over part of its thickness and can be designed as predetermined breaking points or prefabricated area of separating cuts. The separating markings may be arranged in pairs opposite one another, for example on both side faces of the shaped part, the connecting line of opposite markings (or correspondingly long separating markings) running parallel to the extension of the window contact region. By means of these separating markings, a shortening of the body in order to adapt to the thickness of the intermediate wall region is substantially facilitated.

On the outside of the thermal barrier coating or heat insulating layer, the wall structure preferably has an outer shell, which is a weatherproof covering of the wall structure. The outer shell may directly adjoin the thermal barrier coating or be offended by this in the direction of the depth of the wall structure, for example by an air layer or an intermediate layer of a building material, such as a film, a spacer or the like.

The wall structure according to the invention is according to one embodiment particularly preferred part of a ventilated facade with outside weatherproof cover such as a Verklinkerung, stand with outer skin or the like.

The rear ventilation area between window sill profile and outside of the weatherproof covering can be covered by a window sill or the like. The window sill molding according to the invention is particularly adapted as part of the wall structure of a ventilated facade and can be used particularly advantageously for this purpose. On the one hand, this is particularly adapted to the arrangement and attachment in the area between the supporting wall and weather protection panel, on the other hand, this can be particularly easily fitted into the thermal insulation layer of the facade.

According to an alternative embodiment, the wall construction according to the invention is particularly preferably part of a thermal insulation composite system. Here, an outside weather protection cover can be arranged directly on the thermal barrier coating, for example in the form of a plaster layer or other outer skin. The outer skin may be attached to the thermal barrier coating, in particular the outer skin bearing. For example, the outer skin may be adhesively attached to the heat-insulating layer, for example by adhesive bonding, of which a plaster layer sprayed onto the thermal-insulating layer or otherwise applied is included.

Generally, the window sill molding is preferably at least partially or completely covered on the outside by the outer shell of the wall structure.

The support layer may generally account for 25-75% of the strength of the wall structure, or 35-65% or preferably 40-60% of the thickness of the wall structure. Regardless or in combination therewith, the thermal barrier coating may account for 75-25% of the strength of the wall structure, or 65-35% or preferably 60-40% of the thickness of the wall structure. This applies in the context of the invention, in particular in a thermal insulation composite system, as described above.

The invention further comprises a window sill molding, as it results in relation to the wall structure described above, in particular with associated fastener.

It is understood that instead of the window opening in general, a wall opening can be provided and instead of the window used and a flap or other corresponding part of a closure of a wall opening.

a modification of the window sill molding according to Fig. 1 with cover element.

The Figures 1 and 2 show in relation to the invention a window support area with window sill molding 10 in the mounted state ( Fig. 1 ) or with molding in non-pasted initial state ( Fig. 3 ). The wall structure 1 here has a supporting wall 2 with the space outside-side front side 2a and the inside back side 2b. The supporting wall 2 is in Layer structure of the wall outside adjacent to an insulating layer (hereinafter also called insulating layer) 3 pre-set, which is designed here compared to the support wall for a lower load, more precisely here has virtually no load-bearing effect. In particular, the insulating layer consists of conventional insulating materials such as polystyrene plates, etc., the insulating layer material may have a thermal conductivity of about 0.04 W / mK. The insulating layer 3 covers the supporting wall 2 on the outside at least substantially completely. The insulating layer 3 may be connected in a conventional manner with the support wall 2, for example by gluing, pegging or the like.

The support wall 2 is part of a ventilated facade according to the embodiment, so that in the usual structural design in front of the insulation level, an air gap 4 for ventilation and a weather protection panel 5, for example as clinker facade, is set. The support wall 2 limits a window opening or masonry opening in general. According to another preferred embodiment, the wall structure is designed as a thermal insulation composite system, wherein the outer skin of the wall structure is disposed directly on the thermal barrier coating, for example in the form of a pointed or scratched plaster (not shown).

At the window opening, a window sill molding 10 is provided, which has a front side 11 (directed outside the room) and a rear side 12 (room inside aligned) and a bottom 13 and a top 14 has. At the top 14, a support portion 15 is provided for a window frame 50, which projects from the body 16 of the window sill molding 10 upwards. The top of the support portion 15 may be profiled to be adapted to the contact surface of a window frame. The window sill molding 10 is according to the invention attached to the front side 2a of the support wall 2 load-bearing, including as Fixing element 17 may be provided one or more angles, which are on the one hand the sill mold part 10 supportively fixed to this, on the other hand with the other leg 17b on the outer side 2a of the support wall 2. The attachment is in this case designed such that the window sill molding the patch on this window can carry alone, without the window is fixed by means of other fasteners on the supporting wall or other facilities. Optionally, however, the window sill molding at least at the endmontierten window only take over a part of the load of the attached window, with additional load transfer can be done via other load transfer devices, for example, transfer the load in the supporting wall, for example by additional retaining tabs, angle elements or the like.

The fastening element 17 extends in this case to the support area 15 for the window or beyond this, which can apply in general. The window sill molding is in this case - if necessary, except for the fastening means 17 - integrally formed, which can generally apply and is preferred. The one-piece design relates in particular to the cross-sectional structure of the window sill molding. The window sill molding can extend integrally over the entire length of the window opening or be pushed along by other (otherwise preferably identical) window sill moldings, so that therefore have the tailored moldings of a length that results from a certain utilization of foam blocks.

According to the embodiment, the window sill molding is exclusively load-bearing on the support wall 2 and not load-bearing arranged on the superior thermal barrier coating 3. The fastening element 17 can by means not shown screws or other means on the one hand on the window sill molding 10 be attached, so that the two components are secured against each other against displacement and supported, and also be secured against displacement and load-bearing on the support wall 2.

The fastening means 17 is shielded from the insulating layer and the window sill molding 10 to the outside or to the weatherproof cover 5. This applies in particular to the load-bearing region of the fastening means 17, in this case the leg 17b, which is load-bearing towards the supporting wall 2. However, the fastening element 17, in this case the leg 17a, is spaced apart from the front side 3a of the insulating layer 3 arranged on the outside of the space outside. As a result, thermal bridges to the outside are minimized.

Alternatively or additionally, the window sill molding 10 may also be connected by an adhesive layer 18 to the front side 2a of the support wall 2, wherein this adhesive layer 18 may be completely load-bearing by itself in relation to the window 50 attached to the support region 15. Fig. 2 shows another possible - albeit less preferred - mounting option, wherein the sill molding 10 is supported by fastening elements 19 in the form of bolts load-bearing on the support wall 2 and the fasteners 19 extend substantially horizontally and enforce the window sill molding.

The window sill molding 10 has such a horizontal extent that the front side 11 of the window sill molding 10 terminates at least substantially flush with the front side 3 a of the insulation layer or insulation layer 3. The underside 13 of the molding 10 is located on the top of the wall portion 3. To facilitate a cutting and adaptation to the wall portion 3 are according to Fig. 3 on the original mold part 10a release marks 10b, possibly in the form of incisions or prefabricated predetermined breaking points or merely in the form of optical markings provided. Optionally, the window sill molding 10 also more or less, preferably only slightly, protrude beyond the superior insulation layer 3 to the outside. The window sill molding 10 thereby projects over the supernatant insulating layer 3, which can abut directly on the underside 13 of the window sill molding to avoid an air gap and to provide optimum thermal insulation.

In this way, a total of the window sill molding 10 can be attached to the support wall 2 in a particularly simple manner, without also limiting the width of the window opening and thus limit the size of the window to be used. Furthermore, as a result, the window sill molding can be integrated into the thermal barrier coating and partially or preferably completely overhang it. The wall construction is here in combination with a ventilated facade 5, e.g. a Verklinkerung or thermal insulation (ETICS) realized with plaster. As a result, the window can be arranged in a simple manner within the thermal barrier coating of the wall structure, which is advantageous in terms of building physics. The window sill molding 10 also covers the insulating layer on the upper side and thus protects it against possible damage caused by the action of force from above, for example when inserting the window. Furthermore, for the arrangement of the window sill molding according to the invention on the support wall, only the superior insulation layer 3 must be dimensioned with sufficient height to attach the sill molding 10 to the support wall 2 can. However, this is easy because the thermal insulation material can be easily dimensioned according to the respective requirements.

The window sill molding 10 has on the space inside region 21 a shoulder 22, so that the molding surface 23, which is arranged inside the room to the shoulder 22, at the same height as the window sill 2c of the support wall 2 is arranged (optionally, there may be a slight height offset here , preferably less than the 1- to 2 times the thickness of the cover element described below, or less than 0.5 to 0.25 times the thickness thereof, which may generally be considered within the scope of the invention). Furthermore, a cover element 24 is provided, for example in the form of a cover plate whose thickness of the height h of the paragraph 21 at least substantially corresponds and whose length is such that it abuts with a narrow side 24a on the shoulder 22 of the molding 10, on the other with the space inside edge 2d of the support wall 2 can complete. The entire section in the region of the window sill, starting from the front side 3 a of the insulating layer to the back side 2 b of the supporting wall, is thus covered by the molded part 10 and the cover plate 24 towards the masonry opening. The ledge 22 is formed and positioned relative to the support wall such that the cover member placed on the lower horizontal leg 22a and the window sill is disposed horizontally. The space outside area 14a of the top 14 of the molding 10 extends horizontally in the installed state thereof. The outside area 14a of the molding surface is here arranged at the same height as the space inside surface area 14b (above the shoulder 22).

The molded part 10 and the cover plate 24 are made independently of each other of a plastic material, preferably of the same material, here a thermal insulation material such as polystyrene, mineral fiber or other insulating materials. The material has a thermal conductivity value of ≤ 0.06 W / mK.

According to Fig. 3 the window sill molding 10 further comprises a reinforcement 30, which is optional, for example in the form of a metal or plastic profile, for example made of PVC or PE. The reinforcement may be a hollow profile, for example an extruded profile. The reinforcement can within the cavity of the same stiffeners, z. B. in the form of partitions. The reinforcement 30 engages under the Supporting area 15 for the window, so that a part or the entire transverse extent of the support area 15 (ie the space inside space-outside extension thereof) is attacked or supported by the reinforcement. The fastening means 17 for the molded part 10 is formed such that it extends over a part or the entire transverse extent of the reinforcement (room inside-room outside), whereby the window sill molding can also absorb very high loads and wear over its attachment in the support wall. The reinforcement adjacent to the underside of the molding, so that it is seated with a portion 30a thereof directly on the fastener 17 and load-bearing supported by this. This embodiment can apply to all embodiments of the invention.

According to a further modification can after Fig. 4 the body 16 of the window sill molding 40 room inside also have a shoulder 41 which is spaced from the back of the body or the abutment surface of the molding on the support wall. In mounting arrangement of the molding, a step 42 is further formed to the window sill, which projects beyond the window sill. The step 42 preferably has at least approximately the same height h as the heel 41. The cover element 45, here as a cover plate, here also has a step 46 or other height transition, here forming an overhanging region 47, which on the top of the Level 42 of the molding 40 can be placed. The end portion 47 of the cover element is supported in the assembled state on the top of the window sill. The tops 48, 49 of the heel 41 and the cover member 45 are here again at a height, thus forming a preferably horizontal support surface for another component such as a windowsill. By moving the cover element in the direction of the arrow, ie to the back 2b of the support wall 2, the position of the cover element can be adapted to the window sill width without separation of a part of the cover element is required. It then remains a channel between paragraph 41 and end face 45 a, yet is provided by the surface portions 48, 49 a stable support for a sill o. The like.

It is understood that this modification can be combined with the other embodiments according to the invention in each case. Although the masonry opening is slightly narrowed by the step 42. However, the load-bearing area of the body of the window sill molding is also connected to the front of the support wall, so that the constriction is very small. The height of the step 42 and / or the heel 41 is preferably ≤ 3-4 cm or ≤ 1-2 cm. The height of the step 42 and / or the heel 41 is preferably ≦ 25-33% of the height of the abutment region of the molding body to the support wall, more preferably ≤ 15-20% or ≤ 5-10% thereof.
