Description

The present invention relates to a window installation element. A window installation element is intended to be integrated into a wall.

Usually, window and door elements, which consist of a frame and usually a sash element that can be moved relative to the frame, are only inserted into the brick window and door openings after the shell has been erected. The window maker must therefore, as soon as the shell is erected, first measure the brick window and door openings, then the windows and doors are made to measure and finally the window maker must insert the windows and doors into the brick window and door openings and fasten them in such a way that that no thermal bridges are formed.

This method has a number of disadvantages.

The exact dimensions of the brick window and door openings often do not exactly match the dimensions planned by the architect. It is not uncommon for the window openings to differ by a few millimeters or even centimeters, even though the architect has planned a number of identical windows. In the case of made-to-measure production, each individual window must therefore be created with different dimensions, and it is also necessary to clearly label the windows so that the correct window is used in every brick window opening. The same also applies to doors.

The window manufacturer also has to work on the construction site several times. In addition, the production of the windows or doors only after the bricked window and door openings have been measured leads to a construction delay.

Finally, the avoidance of thermal bridges when installing the window or door requires special attention, which can only be guaranteed by specially trained specialists.

Frames have therefore already been proposed which are already "walled in" when the shell is erected, so that these frames determine the exact size of the window or door opening. A measurement is then no longer necessary. In addition, the associated window elements can already be manufactured, since the dimensions of the frame have already been determined before the shell is erected. The window elements can then be fixed in the frame in a further step as soon as it is integrated into the masonry. Such a system is in the DE 8027442 U1 described.

However, the frame described has not caught on because there is a risk that transverse forces will be applied when walling in, so that the cross bars and the reveal parts are no longer exactly at right angles to one another and both the fastening of the frame in the walled opening and the installation of the window element in the frame requires specially trained personnel. For example, the frame must be held until the surrounding masonry is erected so that the frame can be screwed to the masonry.

In the DE 10 2018 121 776 A1 a frame with an upper and a lower crossbar and two reveal parts has therefore already been proposed, in which the reveal parts each connect the lower crossbar to the upper crossbar. To stabilize the frame, a third cross bar is provided to absorb the lateral forces. However, this frame is quite expensive.

Proceeding from the prior art described, it is therefore the object of the present invention to specify a solution which at least partially avoids the disadvantages mentioned.

This object is achieved according to the invention by a window installation element with a window or door element and two side reveal parts, the window or door element having a frame with two side frame parts, an upper frame part and a lower frame part and a filling arranged within the frame, such as a windowpane, has. The two side reveal parts are connected to the frame and the window installation element has an upper, a lower, two side and an inner and an outer surface, the lower frame part forming at least a portion of the lower surface.

Such a window installation element thus consists of the finished window, on the sides of which a lateral soffit part is already attached. This window installation element according to the invention can now be placed, for example, as a whole on the building site on the wall or the floor and then bricked in in the next step. The Indian DE 10 2018 121 776 A1 The third cross bar described can be omitted since the forces are absorbed by the existing window. In addition, other elements that include the window below or above can also be dispensed with, which reduces and simplifies the price and the manageability of the window installation element.

However, it is also possible to brick up the window reveals first and then insert the window installation element into the window opening from above. The window installation element can also be inserted into an existing window opening from the outside or from the inside.

The frame can, for example, surround a window pane. However, other fillings, such as opaque fillings, are also conceivable.

The window installation element is thus placed with the lower frame part of the window frame on the wall or on the floor.

In a preferred embodiment, the lateral reveal parts also each form a section of the lower surface of the window installation element, the lower surface section formed by the lower frame part and the two lower surface sections formed by the lateral reveal parts preferably being arranged in a common plane. In other words, both the side jamb parts and the lower frame part are on the masonry when the window installation element is placed on the wall. The window installation element can then simply be walled in. The presence of the window manufacturer on the construction site is not required at all.

The window is held in its corresponding horizontal position by the lateral reveal parts and the formation of thermal bridges on the lateral reveal parts is prevented. It may also be necessary to insulate the window installation element at least on its lower frame part and possibly also on the upper frame part, which, however, also does not require the presence of the window fitter.

In a further preferred embodiment, the two side soffit parts are fastened with the aid of screws or nails which pass through the side soffit parts into the frame extend, connected to the frame. This allows for a simpler assembly that is also essentially invisible. In the prior art, the window is subsequently installed in the wall opening or in the frame, so that the corresponding fastening elements, such as screws or nails, have to reach into the masonry from the inside of the frame. Alternatively or in combination with this, the side reveal parts can also be glued to the window frame. By providing the window installation element according to the invention, the side soffit parts can be conveniently connected to the window frame by the corresponding fastening elements being knocked or screwed into the frame from the outside through the side soffit parts. After walling in the window installation element, the fastening elements can no longer be seen.

In a preferred embodiment, the side reveal parts consist of a heat-insulating element. Any material with thermal conductivity class WLS 050 or lower can be used as the thermal insulation material. In particular, typical insulating materials such as EPS, XPS, mineral wool, rock wool or organic or inorganic polymer are suitable.

In a further preferred embodiment, the side reveal parts each have a stop rib which projects in the direction of the window frame and against which the side frame parts rest.

This stop rib facilitates the installation of the side reveal parts, since these are now placed against the side frame parts in such a way that the side frame parts also rest against the stop rib, which allows the window frame to move in the direction of the inner or outer surface, depending on the position of the stop rib is positioned, limited. In this position, the side reveal part can be attached to the window frame.

In a further preferred embodiment it is provided that at least one lifting element is provided, which is fastened or can be fastened to a lateral reveal part. In this case, two lifting elements are preferably provided, which are each fastened or can be fastened to a lateral soffit part. These lifting elements can, for example, be correspondingly screwed-on eyelets, with the help of which the entire window element can be suspended from a crane in order to be able to easily position the window element in the right place.

In a further preferred embodiment it is provided that a reinforcement profile is introduced into the lateral reveal parts, which preferably extends over the entire Length of the side soffit part extends. The reinforcement profile ensures additional stability and is preferably made of a metal, particularly preferably of steel. In any case, the reinforcement profile should have a higher flexural strength than the side reveal parts into which the reinforcement profile is incorporated.

In a preferred embodiment, the reinforcement profile is arranged on the side of the lateral reveal part facing away from the frame. Furthermore, it is provided that if a lifting element is present, the lifting element is fastened or can be fastened to the reinforcing profile.

In a further preferred embodiment it is provided that the upper frame part forms at least one section of the upper surface and the side reveal parts each form a section of the upper surface, with preferably the section of the upper surface formed by the upper frame part and the two side reveal parts formed portions of the top surface are arranged in a common plane.

Alternatively, a likewise preferred embodiment provides that a box for a darkening and/or shading system is provided above the upper frame part, which forms at least a section of the upper surface and the side reveal parts each form a section of the upper surface, with preferably the portion of the top surface formed by the box and the two portions of the top surface formed by the side jamb members are located in a common plane.

In a further preferred embodiment it is provided that the lateral reveal parts have a compression insert which consists of a material which has a lower compression modulus than the material from which the lateral reveal parts are made, the compression insert being in contact with the lateral frame part in such a way that that the compression insert is arranged between the side reveal part and the side frame part. During a day or during a year, the temperatures that the window frame is exposed to vary significantly. As a rule, the window frame has the highest coefficient of expansion of the components of the window installation element. If the sun shines directly on the window, especially in summer, this leads to a deformation of the window frame. Since the upper and lower frames mainly expand in the horizontal direction, this causes the side frames to be outwardly deformed at the positions where they are connected to the upper and lower frames, respectively.

The compression insert is intended to absorb the corresponding forces exerted in particular by the upper and lower frame parts on the side frame parts and thereby also on the side soffit parts and to allow a certain degree of deformation of the frame part.

For this purpose, the side reveal part can have a recess in which the compression insert is arranged. The depth of the recess preferably corresponds approximately to the thickness of the compression insert, so that the compression insert is received flush in the recess.

Since, as already stated, the greatest horizontally acting forces on the side frame parts only occur in the area in which the side frame parts are in contact with the upper or lower frame part, in one embodiment each side reveal part can also have at least two compression inserts , which are arranged spaced from each other, wherein preferably one compression insert intersects an imaginary line along which the upper frame part extends and the other compression insert intersects an imaginary line along which the lower frame part extends. As a result, a corresponding compression insert is provided exactly at the points where the greatest forces occur, in which the frame can expand.

Further advantages, features and application possibilities become clear based on the following description of preferred embodiments and the associated figures. Show it:

In figure 1 a first embodiment of the window installation element according to the invention is shown in a perspective view. This window installation element has a window element 1 and two lateral reveal parts 2 . The window element 1 has two lateral frame parts 3, of which in the figure 1 only one can be seen because the other is covered by the side reveal part 2. The frame also has an upper frame part 4 and a lower frame part 5. The upper frame part 4, the lower frame part 5 and the two side frame parts 3 enclose a filling 6, which can be a pane of glass, for example. In principle, however, other materials can also be used here.

The two side jamb parts 2 are connected to the frame. This in figure 1 The window assembly shown has a top surface, a bottom surface, two side surfaces, and an inside and outside surface. The lateral soffit parts 2 completely cover the lateral frame parts 3 on their outward-facing side. In the embodiment shown, the lower frame part thus forms at least a portion of the lower surface. In other words, no further element is provided below the frame. The window installation element can be delivered to the construction site as such and simply placed on a wall or cast floor. In the next step, the window installation element is walled in or cast in. The presence of the window manufacturer on the construction site is therefore usually not necessary. This significantly reduces costs.

At the in the figure 1 In the embodiment shown, the side reveal parts also each form a section of the lower surface, the sections of the lower surface formed by the side reveal parts 2 and the section of the lower surface formed by the lower frame part 5 being arranged in a common plane. The entire window installation element is therefore flat on its underside and can be placed directly on the masonry without the use of appropriate compensating blocks.

The upper surface of the window installation element is also formed in the same way in this embodiment. Here too the surface is formed by both the upper frame part 4 and the side reveal parts 2, the upper surface also being flat.

The side reveal parts 2 can already be connected to the side frame parts 3 by the window manufacturer. For example, they can be screwed to the frame parts or get nailed. The fastening can be done from the outside, ie through the outer surfaces of the side reveal parts 2 . The attachment is then no longer visible when installed. The side reveal parts are made entirely or almost entirely of a heat-insulating material such as polystyrene.

The side jamb parts 2 can be made in a width that corresponds to the width of the masonry. In this case, the window installation element also closes with its inner surface and its outer surface with the masonry. It is also possible to dimension the width of the side reveal parts 2 in such a way that they protrude inwards or outwards with the planned inner or outer plaster thickness over the masonry and therefore form a plaster edge. In addition, the window installation element can be easily packed and safely transported, since the larger width of the side reveal parts 2 in relation to the window element 1 protects both the frame and the filling 6 against unwanted damage.

In figure 2 a perspective view of a lateral soffit part 2 is shown. The side reveal part 2 has a stop rib 7 projecting in the direction of the window frame. On the one hand, this stop rib 7 helps to position the lateral reveal parts 2 relative to the lateral frame part 3 before they are connected to one another and, on the other hand, ensures that as soon as the window installation element is walled in, the window has greater stability within the window opening.

For the installation of the side reveal parts 2, these are placed on the side frame parts 3 in such a way that the side frame part rests against the stop rib 7 both on its edge facing the side reveal part 2 and on the edge facing the outside of the window installation element.

On the side of the lateral soffit part 2 facing away from the frame, a lifting element 8 is provided, which in the example shown consists of a metal eyelet and a corresponding fastening plate with which the lifting element can be screwed to the lateral soffit part.

Such a lifting element 8 is provided on both side reveal parts 2, so that the window installation element as a whole, ie in the figure 1 configuration shown, can be lifted using a crane and transported to the appropriate location.

In order to increase the stability of the lateral reveal parts 2, the lateral reveal part 2 has two undercut grooves 10 on its side facing away from the frame, into which a reinforcing profile 9, which is made of metal in the example shown, is inserted.

The lifting element is then connected to the reinforcing profile 9. The reinforcement profile 9 also has corresponding undercut grooves 10, which are used for the assembly of other components, such as wall anchors, which project laterally and are integrated into the masonry.

The side reveal part 2 also has a groove on the side facing the frame, in which a guide rail 11 is accommodated. The guide rail is used to hold a roller shutter or a venetian blind system.

In figure 3 an alternative embodiment of the invention is shown. This differs from the figures 1 and 2 shown embodiments essentially in that the guide rail 11 was dispensed with and instead of the lifting element 8 ceiling anchors 12 are provided on the side reveal parts 2. These ceiling anchors 12 are intended to engage in the lintel boarding to be arranged above the window or the overlying ceiling boarding, so that after the cast lintel or the poured ceiling has hardened, the ceiling anchors remain in the concrete and give the window installation element additional stability.

In the Figures 3 to 5 there are shown perspective views and an exploded view of a third embodiment of the invention. The same reference numbers were used for the same components. In the following, therefore, only the differences between the third embodiment and the two previously described embodiments will be discussed.

The window element 1 has remained unchanged compared to the previous embodiments. Here, however, the window installation element also has a box for a darkening and/or shading system, which is designed as a roller shutter box 13 . This roller shutter box 13 is arranged above the upper frame part 4 . This box can also be screwed to the side reveal parts 14 . In this embodiment, the side reveal parts 14 protrude upwards over the upper frame part of the frame, so that they form a receiving space for the roller shutter box 13 .

As in particular in figure 4 can be seen, the upper surface of the window installation element is now formed on the one hand by the roller shutter box 13 and on the other hand by the upper edge surfaces of the side jamb parts 14. Again, the upper surface is planar, ie the portions of the side jamb members 14 forming the upper surface of the window fitting and the portions of the roller shutter box 13 forming the upper surface of the window fitting lie in a common plane.

The lateral reveal parts 2 also have a stop rib 7 which, however, no longer extends over the entire length of the lateral reveal part 14, but only has a length which corresponds to the height of the window element 1. As a result, the stop rib 7 forms a bearing surface 15 on which the roller shutter box 13 can be placed.

In figure 6 Another embodiment of the invention is shown in an exploded view.

This differs essentially in that the side reveal parts 17 each have a compression insert 16 . The compression pads 16 are more resilient than the material from which the side sill panels 17 are made. The consequence of this is that any thermal expansion of the window element 1 that may occur is also possible when the window installation element is in the installed state. in the in figure 6 In the embodiment shown, the compression insert extends over the entire length of the side reveal part 17, so that the side frame parts rest completely on the compression insert.

In this embodiment, however, care must be taken to ensure that the connecting screws are not tightened too much when attaching the lateral reveal parts 17 to the frame, so that the compression insert 16 is not already compressed when the window installation element is installed, so that this further compression is no longer available.

In figure 7 another embodiment of the invention is shown. The side reveal part 18 now has a plurality of compression inserts 16 which are separated from one another by corresponding stop surfaces 19 . The compression inserts 16 are arranged where the greatest extent of the window element is to be expected. In the illustrated embodiment, the frame has not only the already described upper and lower frame parts 4, 5 and the side frame parts 3, but also a fighter 20, which is arranged approximately in the middle between the upper frame part 4 and the lower frame part 5 in the embodiment shown.

When the window element heats up, eg due to intense solar radiation, horizontal expansion occurs essentially in the areas in which the upper frame part 4, the lower frame part 5 and the fighter 20 are connected to the lateral frame parts 3. The compression inserts 16 are now arranged in these areas so that they allow the lateral frame parts 3 to bend. This embodiment also has the advantage that during assembly there is no risk of the compression insert 16 already being compressed too much, since the lateral frame parts 3 rest on the stop surfaces 19 . The screwing is then best done in the area of the stop surfaces 19 and not in the area of the compression inserts 16.
