Description

Field of the invention

The invention relates to a building facade with a framework (also called framework) from posts and bars.

Background of the invention

Building facades are becoming increasingly important in contemporary architecture, both in public as well as private buildings. They are for example in DE 198 30 087 C2, DE 34 19 538 C2, DE 195 16 778 A1 and DE 890 19 78 U1.

The stand or framework formed by vertical posts and horizontal bars may in the manner of a truss a over several floors extending building wall or even completely or partially form a roof. In through the posts and bars formed openings is usually used glass. The system supplier provides posts and bars and other accessories, which are regularly custom-made in the customer's workshop brought and mounted on the site, it may happen that the Parts are also brought to the intended dimensions and installed on site.

Builders and architects strive for the aesthetic effect of a building facade of the mentioned type usually very slim posts and bars on, so the facade Overall makes a slight impression and the front almost completely like glass acts. Windows pose a particular problem with regard to these goals, as they, as in the State of the art, in the overall aesthetic effect of the facade slightly disturbing can. A window is understood to mean an opening (turning and / or tilting) window. Be in the art for the building facade of posts and bars windows provided, this is usually the homogeneity of the facade in a disturbing way interrupted.

The demand for a possible graceful framework of posts and bars including the window is the demand for the highest possible stability of the entire Systems contrary.

As material for the frameworks of posts and bars and the space provided for this purpose Windows are particularly aluminum or steel and wood into consideration (apart from Glass panes, gaskets, plastic etc.). These materials are known in the art used, with aluminum preferably on the outside and wood preferably inside is used. On the outside, in particular, the high weather resistance of Aluminum and inside the aesthetic and haptic properties of wood to advantage.

In view of these objectives, the state of the art already knows the combination of aluminum / wood. However, the prior art systems suffer from shortcomings with regard to the above requirements.

Object of the invention

The invention is based on the object, a building facade of the type mentioned to be designed so that they meet high aesthetic requirements with good stability Slimming and homogeneity are the same, simple and inexpensive to manufacture and on site is easily buildable.

Brief description of the invention

According to the invention, these goals are achieved in that the window a sash made of wood, which is optionally provided on the outside with a metal cover, and that the sash in the closed state of the window on the outside substantially is covered by a fixed to the post or bar frame made of metal. Preferably, the cover is made so that the sash outside "invisible" or at least almost "invisible".

The metal is preferably aluminum, in special cases, stainless steel and / or copper and / or bronze.

Although the state of the art knows window sash made of wood, but he looks to Creation of a continuous interior wood surface, as regularly by the architects is sought, before that also attached to the post or bar parts made of wood, which is visible to a viewer from inside the building. In the state of Technology was also biased in the idea that both the frame of the casement as well as the counterpart on the post or bolt should be made of wood, so that the Fittings for opening the window (ie turning and / or tilting) on both sides in wooden grooves to run.

According to the invention, however, forms a frame of metal, in particular aluminum, without wood, the counterpart to the window sash attached to posts or bars. The sash So in the closed state of the window beats against such a wood-free Frame and conceals this.

The frame of the window sash is preferably close to the post or the bar pulled, i. between the sash of the window made of wood and the post or bar (At the vertical parts of the window frame it is the post and at the horizontal parts of the window frame it is the bolt) so only a relatively deep shadow gap of a few millimeters in height or width, so that, seen from the inside, no metal parts, in particular of the frame, are visible. If necessary, on the room side a Lamination, especially wood, a wood veneer, or decorative foil are applied. are The wooden posts and latches are also created inside the building for the beholder Overall, a completely homogeneous and aesthetically pleasing wooden construction.

In this way, a construction can be achieved for the viewer as out of only consisting of two components appears. Although the construction of a frame, a sash and a post includes only two of these components for the viewer visible, namely the frame and the post or bolt on the outside and the Wing frame and the post or bar inside. Overall, also a construction achieved compared to known facade constructions, fewer steps, levels, Surfaces and components, which also less attack areas for weather-related Influences are achieved.

Conversely, on the outside, a slim and uniform aluminum construction without "disturbing" wood or seal parts. The construction according to the invention of one of Wooden parts exempted frame makes it possible to make it so narrow that it is opposite the posts and bars do not form foreign bodies in the facade. It is possible, to achieve high stability of the facade including the window constructions and Nevertheless, the visible from the outside width of the frame of a window of the width of Essentially adjust posts and bars so that, for example, in the exterior 50 mm wide frame and about 50 mm wide posts or bars parallel with a very narrow recessed joint in between, for example, 20 mm wide.

The preferably made mainly of aluminum frame has an inner part on, which is connected to the outer part of the frame by thermally insulating partitions is.

With the construction according to the invention can commercially available fittings, for example Plastic windows known fittings, are used.

The invention thus combines the very good thermal and aesthetic properties a substantially wooden existing window sash with the likewise Good thermal and general technical characteristics (stability with small dimensions, processing, design, e.g. by powder coating and / or Veneer) of the aluminum frame.

Manufacturing technology, the solution according to the invention has particular advantages:

The system supplier only needs to supply relatively few components that can be delivered on site, i. in usually in the workshop, easily cut to the required size, sawn, can be pre-assembled and mounted on the construction site in a simple way to the facade.

The system manufacturer delivers finished goods to the consumer or middleman Surface. There is no need to produce wood profiles on site. Thus sinks in total, both the manufacturer and the customer (middleman; supplier) as also at the end user's storage costs.

Processing technology does not require on-site vulcanization for seals. This represents a significant advantage of the present invention because only vulcanization With high technical complexity is possible, so not for example on a construction site can be performed, but z. B. already made by the system supplier in advance must become.

The invention also allows the front plane of the glass panes in the windows of the facade to tune to the front plane of the glass panes in the openings, so in total over the entire façade the front glass fronts lie in one level. This is included Appearance of reflections in a facade a not to be underestimated aesthetic advantage. Overall, a very high proportion of glass is achieved on the facade.

Also, the construction according to the invention allows the front surfaces of the frame and the front surfaces of the cover profiles, which cover the mullions and transoms on the outside, lie substantially in one plane, which is also the overall aesthetic appearance significantly enhances the facade.

Another manufacturing advantage of the invention is that the system encoder only three frames are to produce, namely a frame substantially of aluminum (with optionally thermal dividers made of plastic), a window sash Wood and optionally a metal cover (preferably of aluminum) for the outside of the sash.

The window construction according to the invention allows a large number of design options, In particular, the exterior aluminum colors can also be used in the Interior of the facade or the window are adopted.

Another embodiment of the invention provides that one between the metal cover arranged on the sash and the glass of the window seal in a plane parallel to the glass has a much smaller width than the metal cover. hereby creates an aesthetically pleasing image from the outside even when the window is open without disturbing rubber seals or rubber flaps or the like.

Another preferred embodiment of the invention provides that at least one of two thermal dividers, which are provided on the frame, mostly in the direction extends parallel to the glass sheet plane. This is at high thermal separation effect achieved a very small overall depth of the posts or bars attached parts.

Another preferred embodiment of the invention provides that seals on the sash with different thicknesses can be mounted to glass panes of different To build strength.

In this case, a special manufacturing advantage can be achieved in that the said seals have a thickness greater than 1.5 mm, preferably greater than 2 mm. This allows easy on-site processing by miter cutting, thereby in the window corners, the seals are easily mounted in a good sealing manner. In the the corners of adjacent, converging seals press by cutting and oversize the miter cut. Furthermore, in the windows according to the invention no vulcanization of the gasket corners necessary.

The above-explained embodiment of the thermal separation webs of the frame such that a majority of the mass of the divider extends parallel to the window plane allows at the same time the advantage of a stop surface for a seal on the sash at the thermal Form the divider in a simple and stable way.

Another preferred embodiment of the invention provides that between the frame and the post or latch adapter seals are mountable for the different Strengths can be specified, so different glass thicknesses can be used.

Description of preferred embodiments

According to Figure 1, a building facade 10 with bottom 12 and roof 14 of a stud work from posts 16 and bars 18. Between the vertical posts 16 and the horizontal Latches 18 thus arise openings, for example rectangular or square Openings. Depending on the construction, other rectangular or polygonal shapes can also be used arise. In the remaining free openings are glass panes in a conventional manner assembled. However, these glass panes do not allow opening the facade. To open the Facade windows 20 are installed in selected compartments between the posts and bars. FIG. 1 schematically shows four square windows 20 and two smaller windows 20 '.

The enlarged detail A shown in Figure 2 of Figure 1 shows that a frame 24, which essentially covers a still to be described window sash and the firmly connected to posts 16 or latch 18, the same view width plus. The joint 22nd like the posts and bars. The posts and bars are front of deck shells which define the optical appearance widths of posts and bars and are described in more detail below. Between post or bar and frame 24th is a recessed joint 22 of significantly smaller width than the frame or bar or Post. The invention described in more detail below allows the width of the frame to reduce to 50 mm or less. The width of the posts 16 and Bar 18 covering cover shells can be reduced to the same degree, the Width of the joint 22 can be reduced to 20 mm or less, for example.

Details of the construction that makes this possible are shown in more detail in Figures 3 to 5. In the figures, the same components are provided with the same reference numerals.

Figure 4 shows the window sash as it is movable by itself, while Figure 5 the window sash of Figure 4 together with the bolt or post and it fastened components shows. FIG. 5 is a section according to the line B-B of FIG. 3 and 2, thus including a bolt 18. One cut in the horizontal direction at another The location of the window that includes a post 16 looks essentially the same.

Figure 4 shows the casement 26 of the window with a handle 28. The outside of the window is in Figure 4 so left. A metal cover 30 is on the outside of the Casement 26 in floating storage by means of rotary connector 36 or mounting clips assembled. The glass pane in the window sash is so through the wing-aluminum profile stuck to the wood. In this meadow is different thermal expansion coefficient the materials wood and aluminum by the sliding bearing of the aluminum profile Taken into account. A seal 34 seals a glass pane 32 of the window. As shown in the figure, the metal cover 30 is made of aluminum and the gasket 34 of a suitable sealing material, for example a rubber material or like. As shown in FIG. 4, the front side of the front panel of the metal cover is visible 30 a substantially greater width than the outside front surface 34b of the seal 34. An inclined surface 34a of the seal 34 extends to the glass pane 32. As usual, acts it is at the glass pane 32 to a double pane. On wing frame 26 is a seal 38 fixed in a groove and another seal 40 at the room-side end of the Sash. In a modification of this embodiment would also embodiments with Dreischeibenisolierglas, a Dämmpaneel o. Ä. Possible.

A groove 42 serves to receive a suitable fitting (not described here). The visible for a viewer from inside the building inside 44 of the sash 26 is a wood surface because the sash 26 is mainly made of a wood body 46 is formed.

Figure 5 shows the sash 26 of the window in cooperation with the components which belong to the fixed parts of the building facade, so in particular the bolt 18 or Post 16 and the attached front-side components. The borderline between the movable window sash 26 and the stationary components is thus through the seals 34, 38 and 40 marked. As mentioned above, a section looks through casements and posts as well as the section of Figure 5.

On the bolt 18, a mounting rail 48 is attached made of aluminum. The outside covers one Cover shell 50 made of aluminum, the components between this cover shell and the mounting rail 48 off. A known as such clamping profile 52 made of aluminum is provided with a Screw (not shown), which is screwed into a screw 56, against the mounting rail 48 pulled. In this case, a spacer 58 between elastic seals clamped, which are marked in Figure 5 by cross-hatching.

According to Figure 5, the frame 24 is provided with dividers 60, 62 made of plastic, the a thermal separation between the outer parts of the frame 24 and an inner part 64 effect of the frame. The dividers 60, 62 cause a distance between the outer part of the frame 24 and the said inner part in the direction perpendicular to the window plane, wherein the divider 60 close to the window sash 26 characterized in the thermal separation effect is enhanced that much of the mass of this divider extends parallel to the window plane. This will cause the thermal stretch at the same time small depth increased.

As Figure 5 shows, the wood body 46 of the sash 26 is far in the direction of the bolt 18 pulled. The same applies to the post 16. Thus remains between sash 26 and bar 18 (or post 16) only a very narrow and deep shadow gap 68 such that from the inside only the inside 44 of the wood body and the inside of the bolt 18 (or post 16) can be seen, both in the illustrated embodiment Wood, preferably similar wood. In the illustrated embodiment, the shadow gap 68 only 5 mm wide and clearly more than 5 mm deep, so that overall a harmonious and homely wood effect arises on the inside.

A seal 70 seals the glass pane 32 in the sash 26. For the seal 70 Different thicknesses are provided so that glass panels 32 of different thickness can be used.

Figure 5 further shows the groove 42 described above in the wood body 46 opposite one further groove 72 in the existing aluminum part 64 of the frame. The two Grooves 42, 72 serve to receive fitting parts (not shown).

Furthermore, FIG. 5 shows a vertically raised edge 74 on the aluminum inner part 64 of the frame, which serves as a water barrier, so that any penetrating water in the Recess 24a of the frame remains and can not penetrate inward to the wood.

A formed on the divider 60 wall surface 60a extends parallel to the window plane and serves as a seal stop for the opposite seal 38 on the casement 26th

Next, Figure 5 shows an adapter seal 76, the strength of which is variable, so different adapter seals 76 are selected with different strengths can be installed to 32 different thickness glass panes. The same applies to the glazing gaskets 78.

The variable seals 70 and the combination of the variable seals 76, 78 allow a variety of glass thicknesses.

On site, at the customer, no longitudinal machining of the wood parts is required, as well no vulcanization.

Due to the described construction of sash and the post or bar To be fastened components, it is possible that the system manufacturer in a simple way lengths for the aluminum bezel 24, the aluminum cover 30 and the wood body 46 the sash 26 provides. On site, these parts can then easily Conditions are measured and cut and assembled accordingly. Of the mounted frame is insensitive to stagnant water, however, inside becomes a full real wood look allows. Is used in a modification of the in Figure 5 illustrated embodiment, the wooden body 46 of the sash 26 not so far As shown drawn on the latch 18 (or the post 16), it is also possible to be at the Outside the sash frame to attach a wooden panel, which then has a larger shadow gap 68 largely covers.
