Abstract

arrangement for mounting a window sill and for installation in window reveals as well as for sealing the substructure from penetrating moisture, characterized by an integral formed window pan (8), which on the substructure (3) can be placed on the side as well as flushed with the window reveal or the plaster is and for receiving the sill (8) in the direction of the facade side open on one side.

Description

The The invention relates to an arrangement for receiving a sill and for installation in window reveals and for sealing the substructure from penetrating moisture.

Around when installing windows a good seal of the substructure on the outside in particular to reach down rainwater or driving rain, Various more or less complex procedures have been developed. The optical termination of the substructure, d. H. the top edge the masonry crown, or roughing shell, usually forms a windowsill.

The Windowsill on the facade side has several tasks to perform and Can be made of any moisture-resistant materials, such as natural or Artificial stone, plastic, metal or wood. Have window sills on the one hand an architectural function and on the other hand the task of running down from the window water over a drip edge in front of the Derive facade. The other function of the windowsill is the permanent one and perfect seal against the Substructure, so that it can not be moistened. That would also heat losses, or permanent damage the substructure, especially in wooden structures result.

If building to be built on site in a conventional mono-lithic way, there are sufficient and high-quality opportunities to the desired Seal to ensure. However, a problem here too Here are the different materials used here, where especially their behavior is problematic with temperature changes. So can used sealants become brittle over time, or you can detach from the ground or it can Cracks occur, allowing moisture to penetrate.

at the assembly of precast buildings in Holztafelbauart or with other wall elements, however, arise even more problems.

On the one hand here is the effort to deliver the prefabricated walls pre-assembled to the highest degree, So z. B. with pre-assembled windows, on the other hand the demand for the most complete utilization the transport volume. This means that it is not possible that Window completely including vorzumontieren the required sill, because they survive too far would. Furthermore could the windowsills also easily damaged during transport or during assembly.

consequently the sills are becoming the usual way later mounted, at the same time the necessary seal to the substructure must be made.

For this purpose it is possible to glue an air-tightness layer made of a film or a panel material to the window frame, or to integrate a panel material on the window. 1 (Prior art) shows a seal with a foil 1 , which under formation of a gutter 2 with lateral drainage possibility on the substructure 3 rests on the finally a windowsill 4 is mounted.

2 (Prior art) schematically shows a similar construction in which the on the substructure 3 resting foil 1 with drainage joints 5 combined. The problem is in any case the lateral seal. It also has joints 6 in the wooden frame construction 7 through the foil 1 to be covered with.

at the subsequent Installation of window sills, z. As aluminum or plastic, or natural or Artificial stone, the already completed window reveal must be subsequently damaged, around the window sill laterally sealing in the plaster or in the construction integrate. This is simply because the sill is around certain extent wider must be as the window pane. That requires a considerable extra Installation effort.

To the Sealing joints becomes common swellable and at the same time permanently elastic sealants or elastic Joint seals in the form of profiles between wooden soffit and window frame used.

Is solved the object underlying the invention in an arrangement of the type mentioned by an integrally formed window pan, which can be placed on the substructure as well as laterally in the window reveal or the plaster is einsteckbar and the recording of the windowsill is designed to be open on one side in the direction of the facade side.

The Window sump has a base plate for resting on the substructure and lateral molded wall angles for sealing in the window reveal or in a plaster layer, the depth of the window pan maximum the depth of the substructure corresponds and wherein the window sill with the outside flush with the substructure concludes.

The Window sill is made up completely a plastic, so that thermal bridges avoided can be.

In addition is provide the base plate with a stiffener.

In In a variant of the invention, the bottom plate contains a honeycomb construction to their stiffening and sound insulation on. This will be the transmission safely prevented by raindrops dripping sounds.

In a continuation According to the invention, the window sill is preassembled on a window frame.

Finally is the window sill with the window frame positively and non-positively connected.

The Window sill is still air and waterproof with the window frame or a plaster layer connected.

to air-tight and watertight connection is located between window sill and window frame a labyrinth seal.

In Another embodiment of the invention is the window frame with the window sill in the window reveal in a prefabricated wall section preassembled.

Farther is the windowsill in the window sill without further seals glued into the window pan or otherwise secured, wherein the windowsill is particularly leaky mounted.

The Invention will be explained in more detail below using an exemplary embodiment. In the associated Drawings show:

1 : (Prior art) a sill with a seal with a film with lateral drainage for water;

2 : (Prior art) is a schematic representation of a similar construction in which the resting on the substructure film is combined with drainage joints; and

3 : A section of an inventive arrangement for receiving a windowsill and for installation in window reveals.

According to 3 is a window pan according to the invention 8th provided for installation in a window reveal, which is a bottom plate 9 to rest on a substructure 3 as well as lateral molded wall angles 10 for sealing in the window reveal or in a plaster layer. The depth of the window sill 8th corresponds at most to the depth of the substructure 3 , The window sill 8th closes with the outside of the substructure 3 flush off.

To avoid thermal bridges, there is the window sill 8th completely made of a plastic. In addition, the bottom plate of the window sill 8th with a stiffening in the form of a honeycomb construction 11 , which simultaneously serves the sound insulation, provided. In this way, the transmission of raindrops dripping sounds is prevented safely and without any special effort.

The upper surface of the bottom plate 9 serves to accommodate the windowsill 4 , Like from the 1 . 2 is visible, it must be installed in the installed state to the outside with a slope of 5 °, so that a sufficient drainage is ensured. How on 3 it also has the bottom plate 9 a slope to the outside, so that the windowsill mounted on it 4 has the same slope.

The window pan according to the invention 8th is on a window frame 12 preassembled. This can be done by positive and non-positive connection. The particular advantage of this construction is that the windows are either complete with the window sill 8th pre-assembled to the customer can be delivered. Alternatively, there is also a problem, the window sill 8th Delivered separately and only at the mounting location on the window frame 12 to fix.

The Window sill is still air and waterproof with the window frame or a plaster layer connected.

For the airtight and watertight connection between window sill and window frame is a labyrinth seal 13 provided, in addition a rubber molded gasket 14 can be provided.

The construction according to the invention allows the window frame 12 with the pre-assembled window sill 8th in the window reveal factory pre-assemble in a prefabricated wall and the desired windowsill 4 subsequently installed at the installation site without any special effort. Additional sealing measures in the area of the windowsill 4 , such as the use of slides, omitted.

The commercial windowsill 4 can be glued or otherwise secured without further seals in the window sill, the sill 4 especially leaking is mounted. Here, a full-surface bonding is neither necessary nor useful, so if necessary between windowsill 4 and window sill 8th penetrating water can drain quickly.

The inventive arrangement guarantees a complete and permanent sealing of the substructure.

3 also shows a standard window frame 12 with a window inserted 15 with double glazing 16 ,
