Abstract

The invention relates to construction elements (10) for decorative and stylistic designs or embellishments of buildings, said elements comprising wood-plastic composite materials (WPC).

Description

components

The invention relates to components for the decorative and stylish design or beautification of buildings.

Such components or stylistic elements have long been known and are available in various shapes and designs. So far these are made of stones, for example granite or marble, concrete and sometimes also to a small extent made of wood.

These components also serve the decorative and stylish design or embellishment of facade surfaces and find their particular use in the border of windows, doors and components.

However, these components described above are extremely expensive to manufacture and can be produced only with great effort. In addition, they are very heavy and can therefore be processed only with difficulty. For all these reasons, these components described above are therefore extremely expensive not only in the production but also in the processing. The invention is therefore based on the object to provide components of the type mentioned, which are extremely inexpensive to produce, have low weights and can be mounted extremely easily.

This object is achieved by components of the type mentioned above, when they are made of wood-plastic composite materials. However, in general, the abbreviation of the English name Wood Plastic Composites, in short WPC, has become common in Germany and will be used in the following.

These components made of WPC include window sills, window frames, door frames, base plates, sill profiles, columns, skirting boards, decorative profiles, wall coverings, design elements and decorative parapets.

In general, WPC consists of different proportions of wood, plastics and additives and can therefore be produced and processed by means of thermoplastic molding processes due to the proportion of plastics.

Among others, extrusion, injection molding, rotational casting, pressing or thermoforming are the above mentioned molding processes.

The particular advantage of WPC is the low cost of raw materials, the significant weight reduction compared to conventional components as well as the design possibilities and environmental aspects, since they can be produced with "waste products". Components are particularly advantageous if they are window sills, window walls or door frames, which can be placed or the facade can be attached at an angle. It is meant with attachable that complete the window walls and the door frames with the facade. By contrast, it is meant at an angle that on the one hand the surface of the wall opening and on the other hand a small part of the facade are covered with these window walls or door frames.

Due to the material and also because of the low weight, it is of particular advantage that they can be fastened by gluing, screwing, welding or by clipping on corresponding counterparts.

According to one embodiment of the invention, it is provided that the door frames or window walls are provided with grooves for receiving seals. As a result, it can be reliably prevented that water can occur between the masonry and the component, which then can have the known undesired effects.

If the windows or doors equipped with these components are provided with shutters and / or insect screens, then it is particularly advantageous if the door frames or window walls are provided with first and second recesses for receiving and guiding shutters and / or insect screens. As a result, subsequent working out of these corresponding grooves is unnecessary. Also, this eliminates attaching appropriate mostly U-shaped guide rails to these components for this purpose just mentioned. A further facilitation and time-saving attachment of these components is given when the seals are pre-compressed bands.

According to one embodiment of the invention, it is provided that the door frames or window walls are provided with an insulating layer, which are arranged in the assembled state between the window walls and the masonry.

In order to satisfy all tastes of the buyer if possible, it is advantageous if at least the surfaces visible in the assembled state are coated with lacquer, or have a coextruded color mixture. Also films are applicable with appropriate technology as surface and weather protection.

Furthermore, for the same reason, it is advantageous if at least the surfaces visible in the mounted state are provided with a cover which can be glued or clipped on.

It may be advantageous if the cover made of metal and / or plastic.

A further embodiment of the invention provides that the door frames or window walls are provided with window frames which can either be attached to the components or can also be integrally formed therewith. As a result, the assembly time for the components and windows is reduced even more, since the frame can then be fastened simultaneously with the components. Depending on the need, it is still possible to provide the frame with corresponding internal reinforcements.

A development of the invention provides that in two-leaf windows or doors, a T-piece is connected to the frame or integrally formed therewith.

Again, it is possible that the tee has an internal reinforcement.

Another particularly advantageous embodiment provides that the wings of the windows or doors are made of hollow plastic composite materials (WPC).

It is also possible that also the glazing beads of the windows or doors as above consist of wood-plastic composites (WPC).

Further features and advantages of the invention will become apparent from the following description of several embodiments and from the figures to which reference is made. Show it:

Fig.l is a perspective view of a window trim or a Türumrahmung; A perspective view of a window robe with

Windowsill; 3 shows seven side views of various window garments or door frames; 4 shows a sectional plan view of a complete window or a complete door with angularly enclosing window garments or door frames;

FIG. 10 shows a representation similar to FIG. 9, wherein the design of the component is chosen such that it is formed flush with the casement for the water drainage;

Figure 11 is a similar to Figure 6 representation with an additional layer of insulation between the masonry and pointing to the frame limb of the angled window garment or the angular door frame; and

12a and b show a sectioned top view of a double-leaf door or double-winged window with the frame integrally formed on the angle pieces and with a T-piece made of the same material and an enlarged detail.

Various exemplary embodiments of components 10 will now be described with reference to FIGS. 1 to 12. These

Components 10 serve as style elements for facade construction and serve the decorative and stylish design or

Beautification of the corresponding facade surfaces.

Unless otherwise stated, like reference numerals refer to like objects, at least similar items.

Although only door frames 16 or window frames 14, partially with window sills 12, are shown in the figures, these components 10 can also be base plates, simprofiles, columns, skirting boards, ornamental profiles, wall coverings, design elements or decorative postiles.

In the following, however, only window walls 14 or door frames 16 will be described without acting with respect to the other components 10.

Fig.l and 2 show two basic shapes for window walls 14 and Türumrahmungen 16, wherein in Fig.2 also in addition a sill 12 is shown, which is also to count the above-mentioned components 10.

As already indicated above, the components 10 serve for the decorative and stylish design or beautification of buildings. All components 10 have in common that they consist of wood-plastic composite materials, which in the following to be referred to simply as WPC (Wood-Plastic-Composite), since this term WPC has become established.

Due to the proportion of plastic, it is possible that these components 10 can be manufactured and processed by means of thermoplastic molding processes.

These shaping processes may be extrusion, coextrusion for different colorations, for example, injection molding, rotational casting, compression molding or thermoforming. These thermoforming processes can be used, for example, for the horseshoe-shaped building elements 10 shown in FIG. 3 shortly before complete curing in order to ensure this horseshoe-shaped form.

The rest of the description refers to components 10, the sills 12, window walls 14 and Türumrahmungen 16 are. In this case, a distinction is once made roughly between window casings 14 or door frames 16 which can be placed on the facade 18 and can be placed in the mutually facing surfaces of the wall opening and also surround the facade 18 at an angle.

These components 10 or window frames 14 or door frames 16 can either be glued to the corresponding location of the facade 18 and the masonry 36, so screwed, welded or clipped onto corresponding counterparts 20. 5, a counterpart 20 is indicated.

Both FIGS. 4 and 5 have in common that the corresponding components 10 furthermore have no grooves or the like, 5, the counterpart 20. However, as shown in Figure 6, the window walls 14 and door frames 16 may be provided with grooves 22, in which on the masonry 36 and on the facade 18 attached you - intervene lines or bands 24. Of course, these grooves 22 are aligned in the installed state in the direction of the masonry 36 and the facade 18.

On the side facing a frame 40, FIG. 6 shows the window dressing 14 or the door frame 16 with a first recess 26 for receiving a roller shutter 30 and a second recess 28 for receiving an insect screen 32.

The window frame 14 shown in FIG. 6 or the illustrated door frame 16 is attached to the masonry and additionally has a roller shutter 30 and insect screen 32 in the corresponding first and second recesses 26 and 28, is illustrated particularly clearly in FIG.

Of course, it is not necessary that both a shutter 30 and an insect screen 32 must be present. This is only the choice of the customer.

As can be seen in particular from FIG. 12b, the seals can be pre-compressed strips 24, which have a web 52 facing the masonry 36. By removing this web 52, the seal can then expand and thus seal the component 10 or the window covering 14 or the door frame 16.

Another way of sealing is shown in Fig.11. Here, the window garment 14 or the Türum- Framing 16 provided on the side facing the opening side of the masonry 36 side with an insulating layer 34. This insulating layer 34 forms a coating on the corresponding surface of the component 10 in order to seal off and / or insulate the masonry 36.

Although not apparent in the figures, it is possible that at least the surfaces visible in the assembled state are coated with lacquer. It is also possible by means of coextrusion to provide a color mixture at the corresponding desired locations. But it is also possible to apply with appropriate techniques films as surface and weather protection.

A further possibility of protection of the free surface of the component 10 is given by the fact that at least the surfaces visible in the assembled state are provided with a cover 38, this cover 38 either being glued or clipped on.

Preferably, this cover 38 is made of metal and / or plastic.

Previously, the window walls 14 and door frames 16 were used only as an exclusive ornament.

In FIGS. 9, 10 and 12, however, a further variant can be seen, in which the window covering 14 or the door frame 16 is extended so far that a part of it forms the frame 40 '.

In this case, this frame 40 'may be connected either to the rest of the component 10, preferably this is Frame 40 'but integrally connected to this device 10 and therefore consists of the same material, namely WPC.

As can be seen from FIGS. 9, 10 and 12, a series of seals or corresponding grooves 24 are provided in the region of the frame 40 'made of WPC in order to securely seal the frame relative to a wing 48.

Basically, in Fig.10 substantially the same image is shown as in Figure 9, wherein, however, the frame is formed flush with the outer surface of the wing 48 to ensure a safe water flow. The remaining components are identical to those of FIG.

FIG. 12 a shows a sectional plan view of a window or door 44.

Again, the frame 40 'integrally formed with the window walls 14 and the Türumrahmungen 16.

In addition, since these are double-leafed windows or doors 44, a so-called T-piece 46 is still present in the center, which in this particular case likewise consists of the same WPC material as the others in FIG This figure shown window walls 14 and Türumrahmungen 16.

Furthermore, the frame 40 'and the T-piece 46 are provided with corresponding internal reinforcements 42, which may well have different shapes, as clearly shown in Fig.12a. Another possibility of the design, which is not shown in the figures, however, is that the wings 48 of the windows or doors 44 are made of WPC. It is then also possible to produce the glazing beads 50 also of this material. This ensures a uniform, visually pleasing image.

According to the invention it is therefore possible to produce the previously extremely expensive and laborious to install components much cheaper and also much easier to install. Furthermore, of course, this also makes it possible to inexpensively retrofit wall openings which have no components 10.
