    专利说明:

    The subject matter of the invention is a preassembled, insulated window sill system according to claim 1.
    Window sills form the lower end of window and door openings and extend over the entire cross section of the upper edge of the underlying wall area outside the window in which the window or door is installed. Window sills are therefore extremely exposed to the weather, in particular driving rain that hits a house wall, and serve to drain the rainwater, which also runs down from the window, over the face of the wall. Originally, such window sills in wooden houses were made of one board. In stone buildings, the window sills are usually made of natural or artificial stone. Stone window sills have a high resistance to both water and pollution and therefore represent a valuable part of a building facade.
    Although window sills made of stone and the like are weatherproof, they direct the cold from the outside into the interior of buildings, especially in the cold season. As a result, they no longer meet the newer prescribed high insulation values, as they represent extreme thermal bridges.
    As a replacement for these weather-resistant window sills, the window sills have been replaced by cover and ledge plates for some time, which are placed on the lower reveal of the window. The relatively thin cover plates made of steel or aluminum are supported by boards made of wood, plastic panels or, if need be, the external insulation of the highly insulated house walls made of foam panels. A cold bridge between the cover sheet outside the window, which has high conductivity, and the window or the wall can be prevented by inserted sealing strips or a putty joint.
    [0005] Window sills constructed in this way are installed after the construction work has been completed and the windows and the facade insulation and/or the plaster have been installed. This means that the craftsmen have to prepare the lower edge of the reveal for the attachment or the covering of this area with a cover plate and then let the cover plate into the reveal. Since the dimensional accuracy varies greatly on construction sites, this means that the cover plates and their substructure must be individually adapted for each window. This causes costs.
    In order to simplify this work, it is also known, e.g. from EP 3 121 359, to fasten lateral plaster plates on the lower reveal area, on which a cover plate can then be placed. The cleaning sheets or borders have a substantially horizontal supporting area on which the cover sheets can be placed with play, so that width inaccuracies can be accommodated and an individually tailored cover sheet is not necessary for each window. With this measure, the weather protection with regard to rainwater drainage from the windows can be created in a relatively simple manner. Nevertheless, the substructure for the plaster borders and the cover plate in the window opening must first be created on site and adapted to the prescribed insulation regulations. As a result, individual preparations for the installation of the window sill are necessary for each window opening, which are usually not carried out by the window sill supplier. Individually assembled elements that comply with the insulation regulations are complex to create and require a high level of expertise and precise work on the part of the fitter in order to avoid the formation of thermal bridges and leaks.
    An object of the present invention is to create a window sill system which can be installed by the fitter in window reveals without any special prior knowledge of insulation and water tightness.
    Another object of the invention is to design the window sill system in such a way that it can be manufactured to measure, but not with great precision, and can later be adapted and installed on the construction site.
    Another object of the invention is the prevention and drainage of accumulated rainwater and condensation under the cover plate.
    [0010] This object is achieved by a window sill system according to the features of patent claim 1. Advantageous configurations are described in the dependent claims.
    It is particularly possible through the choice of suitable, factory-connected elements not only to meet or exceed the current or latest knowledge of the insulation regulations, but also to increase the durability and weather resistance against driving rain, condensation and the like. Due to the fact that the window sills are manufactured in the factory, high quality can be achieved without being dependent on the weather and using factory-installed assembly equipment and assembly methods. In this way, the window sill systems can be produced cost-effectively and precisely.
    The combination of two plaster borders, the cover plate and the plaster borders and the cover plate bearing rigid foam support plate simplify the installation of the window sill system on site and several steps can be carried out in the production already in the factory. The front edge of the support plate facing away from the window projects beyond the underlying insulation or the facade cladding or the facade plaster by, for example, 10 mm to 25 mm. As a result, condensation below the cover plate and possibly from a leaking putty joint of the water that has entered between the cover plate and window is routed over the front side of the facade or the external insulation and consequently cannot soil the latter.
    The lugs formed on the connection surfaces of the plaster borders protect the laterally exposed sheet metal edges of the cover plate, so that no complex corner coverings of the cover plates are necessary.
    The attachment of plaster borders in recesses on the support plate allow the exact positioning of the latter with respect to the surface of the support plate to form a second water-bearing surface.
    The rear edges of the plaster borders and the cover plate are angled upwards and form the basis or a side surface for a putty joint.
    Beads or strips of adhesive, which connect the cover plate to the support plate, run in the line of fall, i.e. essentially at right angles or at least at an acute angle, and form a second water-carrying plane under the cover plate. The second water-bearing level prevents rainwater and condensation from penetrating the façade system.
    The invention will be explained in more detail using an illustrated exemplary embodiment. It shows: Figure 1 a vertical section through an insulated wall with a window opening, Figure 2 a horizontal section through the wall and the window opening above the window sill, Figure 3 a perspective view of a cover plate, placed between two plaster borders and arranged on a supporting plate, Figure 4 a perspective view of a support plate and the plaster border before being placed on the support plate, and FIG. 5 a vertical cross-section according to FIG. 1 with a support plate projecting beyond the external insulation.
    In the sectional view running perpendicularly to the facade surface according to FIG. 1, reference numeral 1 designates a window sill system. The window sill system 1 is arranged in front of a window 3 and is arranged on the outer insulation 5 or an outer shell of a wall 7 in the example shown. The wall 7 can be made of concrete, brick or another building material. The outer insulation 5 can be constructed from an organic material such as foam, wool or rock wool and the like. There is no direct connection between the uninsulated or poorly insulating wall 7, which extends to the lower edge of the window 3, and the window sill system. The contact or transition area may comprise a joint of putty, sealing tape or similar material which prevents the ingress of water between the window sill system and the wall 7.
    The window sill system 1 comprises two plaster shelves 9, each with a lateral end surface 11, which is intended to rest against the vertically running lateral reveal 13 of the window opening and a horizontally running support surface 15, on the upper side of which grooves and grooves run preferably parallel to the end surface 11 / or ribs 17 can be formed. The rear end of the rectangular or strip-shaped plaster board 9 is angled upwards and forms a sealing area 19 on the window side for a putty joint to the wall 7. The sealing area 19 abuts the end surface 11 at right angles and is connected to it in a liquid-tight manner, e.g. welded.
    The upper edge of the end surface 11 includes an angled portion 21 which runs parallel to and above the wing 15. The angled section 21 can form the lower end of the plaster. The angled section 21 preferably does not extend completely from the rear end of the closing surface 11 to the front end. In other words, the closing surface 11 projects beyond the angled section 21 at the front and preferably continues inclined at an acute angle. A nose 23 protruding downwards is formed on the closing surface 11 and comes to lie at a distance a from the front face of the outer insulation.
    On the two wings 15 on plaster borders 9 a cover or ledge plate 25 is placed. This rests on the ribs 17, if any. The cover plate 25 has an angled area 27 on the back, i.e. in the area of the window 3; on its front side, the cover plate 25 is also angled and has a substantially longer or higher leg region 29 directed downwards, on the lower edge of which a drip nose 31 can be formed.
    Below the cover plate 25, a support plate 33 is arranged, which is intended to rest on the upper edge of the outer insulation 5. The distance between the cover plate 25 and the support plate 33 makes it possible, for example, to drain condensation on the underside of the cover plate 25, or any water penetrating from the rear in the sealing area, beyond the support plate 33 into the drip nose 31.
    In a preferred embodiment of the window sill system, the support plate 33 projects beyond the structure of the wall underneath, such as external insulation or wall cladding, by an amount of 10 mm to 25 mm. The protruding area can extend over the entire thickness of the support plate 33 or only the upper area of the support plate 33 below the cover plate 25, so that a common front surface is created between the wedge-shaped substructure of the wall and the protruding support plate 33, on which plaster can be applied, for example or a facade made of wood fiber cement or sheet metal can be applied and the connection between the support plate 33 and the substructure is thereby covered and protected from the weather. In other words, the width B of the support plate (33) is larger than the width b of the outer insulation and protrudes accordingly.
    A suitable distance a between the underside of the cover plate 25 and the surface of the support plate 33 can be maintained by strip-like in the fall line of the inclined to the horizontal cover plate 25 formed ribs or strips 34. The ribs 34 can be designed to be self-adhesive as an adhesive.
    The rear facade-side end of the support plate 33 can be sealed with a sealing strip 35 on the one hand with respect to the outer insulation 5 and on the other hand the wall 7 . Driving rain, which penetrates between the angled area 27 and a cement joint 37 , is also diverted through the space acting as the second water-carrying level from the height c above the support plate 33 .
    In a preferred embodiment of the window sill system, a recess 39 corresponding to the width of the bearing surface 15 of the plaster border 9 is embedded in the surface of the support plate 33 in the area in which the plaster borders 9 come to rest. The plaster border 9 is consequently guided laterally after it has been inserted into the recess 39 and the ribs 17 protrude beyond the surface of the support plate 33 by a maximum of the amount b. This ensures that there is always a distance b between the cover and ledge sheet metal 25 and the surface of the support plate 33 and as a result any condensation water or water that has penetrated at the putty joint 37 can flow off via the drip nose 31 .
    Temperature-related changes in the length of the cover and ledge plate 25, which can amount to several millimeters depending on the color and length of the cover and ledge plate 25, are compensated for by the dilatation possibilities of the two ends of the cover and ledge plate 25 on the two wings 15 on the plaster board 9 recorded.
    The two plaster borders 9 are preferably firmly connected to the support plate 33 and are delivered as a preassembled unit to the construction site after the windows have been installed in the window reveals there.
