Description

 Building with facade and facade

The invention relates to a building with a facade according to the preamble of claim 1.

Such buildings are known per se in a variety of configurations.

A particular problem is the placement of functional elements in particular - but not only - the building system technology in such buildings.

The solution to this problem is the object of the invention.

The invention solves this problem by the subject matter of claim 1. It also provides the object also solving the subject of claim 25th

Advantageous embodiments can be found in the dependent claims.

By the subject matter of claim 1 is achieved, the functional elements for the system engineering directly between the facade and at least one or more actual outer - are defined by the outer sides of the floor ceilings - levels of the building. "Direct" means, in particular, that no further façade plane, for example a double façade, is arranged between the functional elements and the floor slabs, which would make the construction more expensive.

The installable functional elements include in particular those of building systems engineering (in particular electrics, ventilation, heating, cooling), but also sun protection devices such as blinds and shutters. The functional elements are particularly advantageously designed and arranged in the receiving space such that they adjoin the storey ceilings flush upwards and downwards.

The flush arrangement of the functional elements virtually in "extension" to the floor slabs between the façade and the floor slabs creates a maximally transparent exterior view, in particular if glass panels are used as area elements between the floor slabs.These optics are not provided by ventilation boxes, parapets or otherwise Because there is no parapet for the system technology, the system technology and other functional elements are no longer visible from the outside, and the room area in front of the façade increases.

In the facade can as surface elements and opening elements such. As sliding window, tilt-turn, turn or folding windows, are integrated.

The advantageous functional integration also opens up new design possibilities for the overall view of the façade.

In addition to insulating glass panes, which offer the advantage of maximum transparency, it is advantageous to use so-called solar panels in the facade, since the line periphery for the solar systems (water / power lines) can be optimally coupled with the functional elements.

Almost ideal, therefore, the arrangement of functional elements for the solar façades in the receiving spaces possible (decentralized system technology, solar energy). The buildings according to the invention with the spaced facades can thus also contribute to a high energy efficiency through a decentralized system technology, wherein the system technology does not reduce the usable surfaces for the solar façade. There are also clear assembly advantages, since first the plant engineering and then the facade or both can be mounted together.

In summary, this creates a highly integrated façade system that also offers the possibility of reducing investment and operating costs.

Although curtain walls which are located directly or at a small distance in front of the outer levels of a building, which are generally formed by the closing surfaces of the floor slabs and parapets, are known per se from the prior art. Curtain facades are used e.g. mounted at a certain distance to these levels in order to arrange insulation material between the facade and the building. The distance of the curtain wall increases slightly z. For example, in ventilated facades, where in addition to the thermal insulation, such as mineral wool, rooms are provided that allow an exchange of air.

The decisive factor here, however, is that the thermal insulation level of the façade according to the prior art is located directly in front of the outer levels of the building or slightly in front of it, so that there is no space for accommodating functional elements of the installation technology.

Also known are so-called double façades, which in addition to a curtain facade have a second shell, which has a greater distance from the heat insulation layer forming facade. For example, this distance can be so great that it can be walked on. Double façades are used for temperature control (heat recovery - cooling). Thus, it is also known to arrange functional components for the air conditioning of the building between the facade forming the thermal insulation layer and the outer shell. Here, however, a double façade is required, which increases the investment costs. The invention avoids this additional expense by the direct arrangement of the functional elements in the receiving space in connection to the outside of the floor slabs before preferably only a single closed facade level. The Plant technology is thus "inside" the building spaces, which simplifies the accessibility for maintenance and the like.

However, all the well-known buildings with functional elements for the plant engineering façades have in common that the thermal insulation level is in direct proximity to the actual outer levels of the building and that they do not meet the desire for high transparency of the buildings.

In contrast, the invention takes a clear step further, since it uses the receiving space specified particularly advantageously in the subclaims directly for accommodating the functional elements, thereby improving the overall appearance of the building.

The invention will be described in more detail below with reference to the drawing with reference to an exemplary embodiment. It shows:

Figure 1 shows a detail of a multi-storey building shown schematically; and FIG. 2 shows a detail section of a building ceiling with a facade.

Figure 1 shows symbolically a section of a multi-storey building 17 with at least two or more floors or floors 18, 19, which are separated by floor slabs, consisting of a concrete floor 1, 2 and possibly a floor 12 and / or a ceiling panel (the latter not shown here) exist.

At the front side or outside to the floor slabs 1 and 2, a front wall 3 forming the outer front of the building is arranged. According to the invention, this facade 3 forms at least part of at least one outer wall or else the entire outer shell of the building 1, which thermally closes the building in its area in the manner of a closed surface to the outside. Apart from the facade, the building itself may be a building of any intended use, for example an office building.

The facade 3 is preferably formed from a rung of profiles. These profiles may be formed as Metallprofϊle, especially as aluminum or steel profiles. The lattice work preferably has bolt profiles 4 and post profiles 5, between which insulating glass panes 6 are arranged as surface elements. Panels, solar panels, such as thermal or photovoltaic collectors, and functional elements, such as sliding windows, can also be used as surface elements.

The facade 3 is preferably arranged wholly or in any case in partial areas spaced from the outer surface, which is predetermined by the outer end faces of the floor slabs.

In this way, a receiving space 20 is formed between the facade and the outer end faces of the floor slabs, which accommodates functional elements of at least one building system technology 7 as a functional space.

It is particularly advantageous if the facade 3 as a whole on its entire surface or at least more than 60%, preferably more than 80% of its surface spaced from the end faces of the floor slabs 1, 2 is arranged. It is essential that not only recesses are formed in the floor slabs 1, 2, but that a large-volume receiving space 20 over a substantial area of the facade is formed, which really take a large part of the building equipment, especially in extension of the front sides of the floor slabs 1, 2 so that a real gain in transparency, especially when used on office buildings with transparent surface elements.

FIG. 2 shows a detail section of a building ceiling 1 with the facade 3, wherein the facade 3 is so spaced from the floor slab 1 that between the floor Schossdecke 1 and the facade 3 twice functional elements at least the system technology 7 and 8, are arranged.

1 with one of the concrete ceilings of the building is characterized, which has an arbitrary width 13 in the horizontal plane and defines vertically on its outer end side an outer plane X of the building.

On the concrete floor 1 is an elevated floor 12, so that the entire floor ceiling here by way of example a vertical thickness - here referred to as height H - of about 400 mm. Instead of or in addition to a raised floor 12, a suspended ceiling can be arranged below the floor ceiling.

Almost flush with the top 15 and the bottom 16 of the entire floor ceiling closes the receiving space 20, which has a horizontal width 14 and a height H. In the room are functional elements, e.g. for the systems engineering, added. In addition, the receiving space 20 receives a Geschosentrennung 11 and insulating material 10.

By a flush arrangement a maximum transparency of the building is achieved (see also Figure 1). Preferably, none of the functional elements are higher than the height H of the floor slab, so that the review is not hindered.

The functional elements preferably include ventilation devices for air conditioning of the rooms and associated air ducts (baffles, flaps, filters). Since these ele- ments of the system technology 7 and 8 (in particular ventilation units for ventilation, heating and cooling) usually record a width of, for example, 400 mm, it is advantageous if the width of the receiving space, ie the distance between the facade 3 and the End faces of the floor slabs 1, 2 is preferably 400 mm or more. Between the systems 7 and 8, which can be coupled together, there is a plate-like partition 11, which acts soundproofing and meets fire safety requirements. The storey separation can also be arranged above or below the installation techniques 7, 8.

Front side to the functional elements of the system technology 7 and 8, opposite the floor slab 1, can e.g. an insulating layer 10 are arranged for thermal insulation. Following this are e.g. the bar profiles 4, which form the rung of the facade with the surface elements 3.

The functional elements may also include sun protection elements, such as blinds and shutters, which can be arranged within the width 14 in front of the system technology 7 and 8 in the sun protection chamber 9 (not shown here).

As surface elements fixed fields (insulating glass panes) or Öffhungselemente, such. As sliding or folding windows are used. It is also possible and particularly advantageous, e.g. Solar panels (both photovoltaic as well as Thermie), as the entire line periphery - especially water pipes for heating or electricity for ventilation fans or heat exchangers - can be coupled directly to the Angegentechnik 7 and 8.

A building with the width 14, which forms the functional space according to the invention between the actual outer level of the building and the facade, can be designed, for example, between 200 and 800 mm. In a particular embodiment, the width 14 is approximately 550 mm. Preferably, minimum widths of 500-700 mm are preferred. Further advantageous minimum dimensions are 200 mm, 300 mm, 400 mm, 500 mm or even 600 mm. REFERENCE NUMBER
